(Universidade Federal do Pará, 2011-04-01) SILVA, Ingrid Ferreira Soares da; FERREIRA, Eleonora Arnaud Pereira; http://lattes.cnpq.br/6600933695027723
Diabetes mellitus type 1 (DM1) is a chronic degenerative disease of major impact on the quality of life of children and adolescents. The DM1 affects predominantly children and young adults under 30 years of age with peak incidence from 10 to 14 years of age. As a chronic disease it involves changes in daily habits, and rule following becomes a key behavior to achieve such changes. This study aimed to examine factors that influenced the behavior of following the rules prescribed for the treatment of adolescents diagnosed with DM1. These rules relate specifically to the measurement of the blood glucose, the usage of the diet plan in choosing the menu and the application of insulin. The study included two adolescents aged 14 and 17 years, diagnosed with DM1, which had difficulties in controlling the disease according to medical evaluation. Also included as participants of this study were those responsible for each adolescent. The following survey instruments were used: 1) Set of interviews with the parents; 2) Inventory of parenting styles; 3) Questionnaire to evaluate the quality of life of adolescents with DM1; 4) Set of interviews with the adolescents; 5) Diabetes social support questionnaire – family version; and 6) Self monitoring forms for Treatment Compliance Behavior. The data collection was performed in the households of the adolescents. The procedure involved the following steps: 1) Selection of participants; 2) Individual interviews with the parents/guardians; 3) Individual interviews with the adolescents, including applications for inventory on their support network, characterization of the baseline behavior of measuring blood glucose, tracking diet plan, and insulin administration, interviews with positive feedback, and final interview. The results from the analysis of compliance behaviors and from the environmental factors reported by each participant throughout the research identified that the participant which emitted compliance behaviors appropriately had a good quality of life, a good level of knowledge about DM1, his parents owned a positive parenting style, perceived support provided by family, besides having a social condition satisfactory to meet the needs of the family. But the participant with a low compliance, although demonstrating a good quality of life, his parents were using a lot of negative practices, despite their parenting style being also positive, the family support perceived by the participant was inconsistent and his social status was insufficient to provide all the tools necessary for his treatment compliance. Thus, it was possible to analyze the factors that influence compliance to treatment, however further research should be conducted using a larger number of participants and also have a longitudinal character, with long-term monitoring to verify the effect of the variables described in the research along the lives of the participants.

Adultos e adolescentes autores de agressão sexual: características biopsicossociais e suas percepções sobre infância, adolescência e violência
(Universidade Federal do Pará, 2021-09-10) SILVEIRA, Víviam da Silva; REIS, Daniela Castro dos; http://lattes.cnpq.br/8805305887566391; https://orcid.org/0000-0002-9505-4516; CALVACANTE, Lília Iêda Chaves; http://lattes.cnpq.br/4743726124254735; https://orcid.org/0000-0003-3154-0651
Sexual violence encompasses all societies, and manifests itself in different ways in their different contexts. This phenomenon is present throughout the life trajectory of many children and adolescents, whether as victims or perpetrators of sexual aggression. With the purpose of investigating this phenomenon, this dissertation presents a research with an empirical-descriptive design and quantitative-qualitative data analysis. The research sought to investigate the perceptions of adults (+ 18 years old) and adolescents (12 to 18 years old) perpetrators of sexual aggression against children and adolescents about childhood, adolescence and sexual violence, relating them to the biopsychosocial characteristics that define the two age groups involved in the research. Therefore, two studies with similar methodological characteristics were carried out, thematically interconnected, but with individuals from two different age groups. Study I sought to investigate the relationship between perceptions of adult perpetrators of sexual assault against children and adolescents about childhood, adolescence and sexual violence and the biopsychosocial characteristics of this age group (+ 18 years), which includes men sentenced for crimes of sexual violence in units prisons. Ten (N=10) interviews conducted and transcribed between 2015 and 2016 were selected for content analysis by the Descending Hierarchical Classification (CHD) with the support of the Iramuteq Software. The results showed that 90% of these adults were over 30 years old; as for education, 50% did not complete elementary school; 10% attended incomplete high school and 30% managed to complete high school, of these participants only 10% had access to incomplete higher education. All participants experienced situations of violence throughout their life trajectories, and regarding the degree of severity of the sexual assault committed, 40% of the authors assumed the practice with hands on; 40% did not assume such aggression, and 20% of these declared that they do not remember the act for which they are serving their sentence. The perception of these adults about childhood, adolescence and sexual violence appears directly linked to the experiences of these participants in the different stages of their development, in addition to not disassociating this form of aggression from the use of physical force. Study II aimed to investigate the relationship between the perceptions of adolescents who perpetrate sexual aggression against children and adolescents about childhood, adolescence and sexual violence and the biopsychosocial characteristics of this age group (12 to 18 years old), which brings together adolescents who respond in court for an analogous offense to the rape of a vulnerable person and who were in compliance with a socio-educational measure. Four (N=4) participants were reached for content analysis of the interviews transcribed through the CHD of Iramuteq. The results showed that the adolescents were over 15 years old. In terms of education, 2 (50%) had not completed elementary school, 1 (25%) had not completed high school, and 1 (25%) had not completed this information. As for the violence suffered, it was observed that all participants experienced situations of violence. With regard to the degree of severity of the act performed, none of the participants assumed their practice in hands on. The perception of these adolescents about childhood, adolescence and sexual violence appears as a reflection of the construction of these categories throughout the life trajectory of these individuals, highlighting sexual violence linked to the use of physical force. Therefore, through the two studies, the hypothesis that there is a greater number of similarities than differences in the reports of these individuals (adults and adolescents) about the perceptions of sexual violence was taken into account. It is possible to point out the relationship between the biopsychosocial characteristics of the two age groups of perpetrators of sexual aggression, and particular ways of dealing with the experiences present in their life trajectories. It is possible to affirm that adolescent and adult authors, despite being in different groups, were probably socialized in very similar cultural and belief systems, which can influence and direct the construction of perceptions that are close to each other. However, adult authors tend to refer to violence as separate chapters in their life trajectory, and in the opposite direction, adolescents tend to show a direct relationship between sexual violence and issues experienced during their previous stages of development.

The group of deaf people in Brazil is considered significant. Deafness can lead to emotional disorders, among them anxiety. Thus, the aim of this study was to measure anxiety reported among deaf and hearing people, with application of the Visual Analogue Mood Scale (VAMS) standard and adapted to Brazilian sign language. The sample consisted of 62 participants were divided into hearing group (n = 31) and deaf group (n = 31) mean age of 31 (±7.53) and 31 (±7.69) years, respectively, of both sexes, paired for age, sex, income and education level . The application of VAMS were individually and data were analyzed for factors: anxiety, physical sedation, mental sedation, other feelings and the total index scale. The data was preceded by the application of the normality test (Kolmogorov-Smirnov) and equal variance test. For data that obeyed these tests, we used the Student t test to compare the factors of VAMS; between groups, between male and female, within groups and between groups; at different income levels, within the groups and between groups; in different years of study, within groups and between groups. When it was not possible to satisfy the criteria of normality and homogeneity of variance test was used non-parametric Mann-Whitney (U). It was adopted a significance level of p ≤ 0.05. We analyzed the correlation in the variables, income, education level and age with each of the scale factors, in the hearing group and the deaf group. The results showed statistically significant difference between groups in the index of physical sedation, being lower in deaf than in the hearing group. In the analysis between groups, hearing and deaf, distributed by sex, was expressed statistically significant in the factor other feelings, being higher in the deaf, both females and males in relation to the male hearing group. In the variables income and education level were statistically significant differences in the components of VAMS, anxiety, mental sedation and physical sedation, between and within groups. In the correlation analysis, the hearing group, positive correlation was found in the variable income and education level versus physical sedation and positive correlation in the variable age versus anxiety. In the deaf group was a positive correlation in the variable age versus physical sedation. We conclude that the use of scales to assess anxiety is important and valuable for field research, and VAMS adapted to Brazilian sign language was sensitive to evaluate anxiety in deaf, it facilitates the inclusion diagnosis of this specific population, which is sometimes sub diagnosed.

Análise da escolha individual na distribuição livre ideal: comparando diferenças e razões
(Universidade Federal do Pará, 2016-01-13) SILVA, Thaís Tavares da; TONNEAU, François Jacques; http://lattes.cnpq.br/2917023797307669
Optimal foraging theory, as a way of understanding foraging behavior, provides a foundation for the Ideal free distribution theory, which seeks to explain the choices of subjects under the condition of group competition. However, although many experiments have been performed to assess the Ideal Free Distribution (IFD), deviations have been observed in relation to the predictions of the IFD, both in other species and in humans. Sokolowski et al. (1999) have proposed an explanation for such deviations in terms of equalizing differences (nG-WG)-(nRWR) instead of ratios (WG/nG-WR/nR). Here we proposed an experiment in which individuals conducted their choices with a software that simulated the choices of subjects in a group. The software was developed in order to clarify the role of respective equations (ratioor difference-based) or choices strategies, fitting the data with a sigmoidal function. The dependent variable was the choice of every subject while being presented with artificial situations. The results showed that subjects performed their choices under the control of the two strategies, as well as others. This study brings relevant contributions to the study of individual choices, in addition to providing data that deserve to be analysed in more detail by future research.

The behavior determination debate lasts since Antiquity, usually based in dichotomic arguments. Actual tendency of behavior determination comprehension points out to an interacionist perspective, analyzing genetic, biological and environmental influences combined over behavior. Many empirical researches have been developed to identify which factors are responsible for a specific behavior. Considering impossible to make a complete study of human behavior determinants, it was chosen to focus into a specific padron the homosexual behavior. Since Antiquity until nowadays, homosexual behavior determinants have been debated. Besides, this subject concerns to a large amount of people and reflects in important social issues. The present study had the purpose of analyzing which are the empiric evidences about homosexual behavior determination, through three stages: (1) historic evolution of the behavior determination, with emphasis on the methodologies applied; (2) presentation and discussion of the main research strategies about homosexual behavior determination, with emphasis on the critical analysis of data; (3) discussion of research implications and possible empirical follow-up. A bibliographic search was conducted, identifying six main research strings: hormonal measures, hormonal effects, genetic, cerebral functioning, animal models and environmental effects. Each research methodology and results were critically analyzed. Then, politics influence over research and the ethical consequences of data release were discussed; as existing data were organized into a proposal to understand the phenomena. It is expected to have contributed to a general description of the actual stage of homosexual behavior determinants as to a critical perspective over methodologies applied.

Análise do efeito de histórias experimentais e de consequências relatadas na regra sobre o comportamento de seguir regras
(Universidade Federal do Pará, 2012-12-17) CARVALHO, Nayra Cristine Alves de; PARACAMPO, Carla Cristina Paiva; http://lattes.cnpq.br/9018003546303132
The present study aimed to compare the effects of the presentation of a rule that specifies small and immediate reinforce, with a rule that specifies large and delayed reinforce, manipulating the order of presentation of these rules, their presentation form (isolated or concurrently), the form of distribution of points obtained in the study and the time interval to exchange these points for money. 32 undergraduate participated in the research, divided equally into two experiments that differed only by the form of distribution of points earned and the time interval to exchange these points for money. Each experiment consisted of four conditions. It was used a matching-to-sample procedure; the task consisted in pointing to each one of the comparison stimuli in a given sequence. In both experiments, the Conditions 1 and 3 consisted of four experimental sessions. In Sessions 1 and 3, rules were presented separately and at the Sessions 2 and 4 concurrently. The Conditions 2 and 4 were composed of three sessions. In Sessions 1 and 3, rules were presented concurrently and in Session 2 separately. The order of presentation of the rules was manipulated in each condition. In Condition 1 the order of presentation was - RI / RIRA / RI / RIRA, in Condition 2 - RIRA / RI / RIRA, in Condition 3 - RA / RARI / RA / RARI and in Condition 4 - RARI / RA / RARI. In Experiment I, the delay was limited to distribution points during the session, following the rule RI produced points during the sessions and following the rule RA produced points only at the end of the session, the exchange points for money was at the end of research. In Experiment II, following RI and RA produced points during the sessions, but the exchange points for money for following RI would occur at the end of the research and for following RA, the exchange would occur a week later. In Experiment I , 15 of the 16 participants and in Experiment II 13 of the 16 participants followed the rule RA, independent of a prior history of reinforcement for following the rule RI and independently of the rule RI producing points immediately, exchanged for money at the end of research. The results of both experiments indicate that the control by the rule that described consequences of greater magnitude, but delayed (RA), prevailed over the control by the rule that described consequences of smaller magnitude, but immediate (IR), even when the exchange points obtained in the sessions for money was postponed for a week. These results suggest that the probability of occur following rules may depend, in part, on the type of consequence related in the rule, namely, of the formal properties of the rule, and not exclusively for reinforcement history for rulefollowing Behavior.

Animal models have been a useful tool in the study and treatment of anxiety. Parametric studies are important to ensure these models validity since they help to identify witch parameters of the model are relevant to produce anxiety-like behaviors. The Plus-maze with Ramp is an anxiety model for fishes, adapted from the Elevated Plus-maze with Ramp. The present study consists of a parametric analysis of the zebrafish’s response in the Plus-Maze with Ramp, evaluating the effects of sex, ramp inclination, light level and arms width. Results showed that, regardless of any manipulation in the evaluated parameters, the animals preferred the flat arms instead of arms with ramp, that the light level of 700 lux increased the animal’s general exploratory behavior and that the ramp inclination of 34,43º increased the total number of entries in the flat arms. The plusmaze with Ramp seems to be a valid model for the study of anxiety in fish and the standard measures of the apparatus seems adequate.

Um análogo experimental de uma prática cultural: efeitos de um produto agregado contingente, mas não contíguo, sobre uma contigência de reforçamento entrelaçada
(Universidade Federal do Pará, 2010-04) LOPES, Eduardo Barbosa; TOURINHO, Emmanuel Zagury; http://lattes.cnpq.br/5960137946576592
According to Skinner’s causal model of selection by consequences, human behavior is a product of three levels of selection: phylogeny, ontogeny and culture. Empiric investigations of the third level just recently begun in behavior analysis. In the theoretic field, Glenn introduced the concept of Metacontingency to describe functional relations between interlocked reinforcement contingencies and an aggregated outcome responsible for the selection of the interlock. In laboratory, a pioneer work by Vichi, reproduced a metacontingency using a procedure adapted from experimental studies in sociology. Vichi suggests that the interlocking behaviors of a small group of people could be modified by the aggregated outcome produced by the interlock, in this way, characterizing a metacontingency. The present work is a replication of Vichi’s study, with the objective to verify if interlocked behavioral contingencies can in fact be selected by an aggregated outcome contingent to the behaviors of people of a small group microculture. The participants were eight undergraduate students, divided into two groups of four, who accomplished a group task. The task consisted in a problem to solve by choosing a cell in a matrix composed of 8 columns and 8 rows, containing positive and negative signs. On each trial, the participants chose one row and the experimenter chose one column. A positive sign in the intersection of the chosen row and column resulted in gains for the group; a negative sign resulted in losses. The column chosen by the experimenter was contingent to the way in which the gains were distributed by the group (equally or unequally) in the immediately anterior trial. In experimental condition A, the positive sign was contingent to an equal distribution of gains, and in the experimental condition B, the positive sign was contingent to an unequal distribution of gains. Group 1 presented 43% of correct choices (the participants distributed the gains accordingly to the experimental condition imposed), and the group 2 made 19% correct choices. These results showed that procedures which use contingent consequences (win or lose in a trial) without contiguity with the interlock, make it difficult to select such interlock. However, interlocked contingencies of reinforcement were selected by its aggregated outcome under variables not controlled in the experiment. This phenomenon can be characterized as an experimental analogous of a metacontingency. The procedure, possible improvements of the procedure and the complexity of the experimental task are discussed. Emergent superstitious rule patterns of behavior are also discussed.

Behavioral analysts have developed a number of methodologies, especially from the stimulus equivalence paradigm, to investigate reading skills in children with learning disabilities. However, few studies involving exclusion have proposed to investigate reading teaching in individuals with atypical development. When it comes to children with autism spectrum disorder (ASD), study has not been identified in the literature. Therefore, this research aims to investigate whether the exclusion procedure combined to CRMTS is effective to establish arbitrary relationships between figures and printed words for children with ASD; if the naming of printed words emerges after training; and finally, if the reading of new words occurs. The data indicate that the training involving the exclusion and CRMTS procedures were effective to establish arbitrary relations between figures and printed words with little exposure to errors and to generate the reading of the dissyllable words in the naming tests. However, the procedure was not sufficient to emerge the recombinative reading of the new words.

Associação de emissões vocais de macacos-prego (Cebus apella, Primate, Cebidae) a contextos comportamentais em cativeiro
(Universidade Federal do Pará, 2008) MARQUES, Karoline Luiza Sarges; SILVA, Maria Luisa da; http://lattes.cnpq.br/2101884291102108; GALVÃO, Olavo de Faria; http://lattes.cnpq.br/7483948147827075
The vocalization is an important form of communication in primates, because the majority of the species lives in dense forests, what makes difficult visual communication at a distance. The Cebus apella species presents a rich vocal repertoire contextualized to diverse behaviors, as feeding, foraging, predators avoidance, contact, copulation, and others. Aiming to elaborate a vocalization data base of sixteen Cebus apella captive subjects, we collected, at the Experimental School for Primates biotery of Federal University of Pará, vocalizations emitted in natural occurrences (agonism, contact) and in designed experiments (individual meal and alarm). The vocalizations were recorded, edited, and the sonograms were made and analysed. At least ten distinct vocal emissions, grouped in different contexts (feeding, alarm, agonism and contact) and the behaviors without vocalizations were mapped. Our data confirmed that Cebus apella species, own an extensive vocal repertoire, with different calls associated to particular behaviors, exhibit sexual differences in calls and sound unity combinations, in agreement with indications of the cerebral plasticity and the social complexity of the species.

This dissertation aimed to investigate the perception of mothers and grandmothers of children with characteristics of ADHD regarding their parental self efficacy and general self - efficacy and also the perception they present about the characteristics of their children. Its structure consists of two interdependent studies. The collection environment for both studies was the Center for Health Care of Women and Children (CASMUC-UFPA). In the first, the objective was to investigate the perception of self-efficacy of caregivers of children with ADHD characteristics, considering the subtype of the disorder and the children's total intelligence quotient. Twenty-four caregivers older than 18 years participated; self-reported as primary caregiver for children aged 6 to 12 years. The exploratory interview protocol was used; Parental Self efficacy scale; EAEG; SNAP IV; Wisc IV. The data from this study showed that the caregivers presented lower values of parental self-efficacy and self-efficacy related to general aspects of life. The lowest levels were linked to ADHD cases of the combined subtype. From the application of Wisc IV, it was observed that in both groups of caregivers, with low and high parental self-efficacy, the children presented Total Intelligence Quotient below the expected average for the age group. In the second study, the objective was to describe the perception of mothers and grandmothers about the characteristics of the child with traits of ADHD, as well as the relationship that these caregivers have with them and the perception about the role of being a caregiver. Participants were six mothers / grandmothers of children between 6 and 12 years old. The instruments and techniques used were an exploratory interview protocol and a focus group interview. Data were analyzed via SPSS- (version 20.0) and content analysis. The qualitative analysis of the data revealed in the discourse of the parents the following categories: 1) Perception of the first difficulties; 2) Perception about the child (positive perception and negative perception of behavior); 3) Perception about the parental partner (Collaborative Perception and Non-Collaborative Perception); 4) Perception of third parties about the child; 5) Assistance services; 6) Risk factors (social risks and spirituality); 7) Protection factors (Spirituality and Availability for care). It is hoped that the data presented in both studies will contribute to the investigation of the mental health of caregivers of children with mental disorders and will provide the basis for the creation of public policies that intervene in the psychological well-being of caregivers and children.

Autores de agressão sexual de crianças e adolescentes: experiências adversas na infância e fatores associados

Studies that identify the different profiles of sex offenders against children and adolescents have been more explored in the literature, however, the investigation of their life trajectory remains less observed in the Brazilian population, mainly from the perspective of Bioecological Theory of Human Development. This study aimed to demonstrate possible relationships between Adverse Childhood Experiences (ACE) and personal and situational factors in the bioecology of the development of male sex offenders against children and adolescentes (n = 30), who were serving time in prison units located in the mesoregions of the state of Pará. To this aim, a system of categories was built based on the ACE-IQ Test instrument, which defines ACE as potentially traumatic experiences that become a source of chronic stress, with negative outcomes for development at later ages. The results were analyzed from two different stages: the first, quantitative, where the descriptors of the occurrence, frequency and typology of ACE were identified, and a second, quanti-qualitative, in which excerpts from the interviews with sex offenders were inserted into the Software IRAMUTEQ to perform simple and multivariate textual analysis. In this sample, 96.67% of sex offenders reported having experienced at least one subcategory of ACE, while more than half (60%) revealed four or more, with an average of 4.36. Physical abuse was the most reported ACE (70%), being mainly related to the figure of the mother, while the death and/or divorce of parents (56.67%) and substance abuse in the domestic context (53%, 33) were related to the father. About 40% of the participants reported experiences involving sexual abuse, whose reports specified characteristics such as age and bond with the possible perpetrator, while social violence appeared mainly in contexts of ecological transition from childhood to adolescence. It was observed that experiences of death and/or divorce of the parents, emotional neglect and domestic violence in the trajectory of sex offenders in this sample can increase the risk of experiencing sexual abuse in childhood. Participants with higher ACE scores abuse children more frequently and with less need of alcohol or other drugs use. The results reveal the existence of a relationship between the frequency and tipology of ACE and factors related to the commitment of sexual aggression, demonstrating that this is a variable to be considered in the investigation with sex offenders, since the effects of stress resulting from such experiences can manifest both in the short and long term, influencing the future adoption of sexually abusive behaviors. It is suggested that further studies may directly apply the ACE-IQ Test to larger samples, with the realization of a post-test to provide greater reliability to the collected reports.

Successive matching-to-sample (go/no-go) has been pointed out as an effective procedure to reduce stimulus control digressions in conditional relation training with non-humans. Other studies suggest the comparison between (symmetrical and non symetrical) conditional discrimination acquisition curves as a way to evaluate properties of equivalence relations. This study aimed to evaluate the potential of using both procedures above mentioned in evaluating the property of symmetry in four capuchin monkeys (Sapajus spp). Stimulus presentation, activation of devices, and response recording were automatically controlled by software. Subjects were maintained under conditions approved by IBAMA. By mean of an “ABAB” single subject design, the acquisition of symmetrical (A) and non-symmetrical (B) conditional discriminations were compared. In both Condition A and B, conditional relations A-B and B-A were simultaneously trained so that in every condition, four new arbitrary conditional discriminations (with new stimuli arbitrarily related) were presented. When symmetrical, positive combinations were A1-B1, A2 B2, B1-A1, and B2-A2, and negative combinations were A1 B2, A2 B1, B1 A2 and B2 A1. When non-symmetrical, positive combinations were A1 B1, A2 B2, B1 A2, and B2 A1, and negative combinations were A1 B2, A2 B1, B1 A1 e B2 A2. Two of the four subjects (Negão e Bongo) completed que acquisition of one (Bongo) or two (Negão) sets of conditional relations (Conditions A-symmetrical and B-non-symmetrical) for the evaluation of the viability of the procedure to verify the property of symmetry. Data demonstrate that the method here reported detected the presence of the property of symmetry in the conditional relations leraned by Negão and its absence in the conditional relations learned by Bongo. Data are inconclusive for the other two subjects. One detailed analysis of the performance of each subject and its measures is also presented.

Avaliação psicopedagógica de crianças em acolhimento institucional
(Universidade Federal do Pará, 2013-03-06) PINHEIRO, Marcilene Alves; MAGALHÃES, Celina Maria Colino; http://lattes.cnpq.br/1695449937472051; OLIVEIRA, Ana Irene Alves de; http://lattes.cnpq.br/8839751954613395
One of the great challenges of contemporary society is to address the issues surrounding the care of children and adolescents in institutions and the possible consequences of that period in their development. Current studies seek to look at the host institution as developmental context from the perspective Bioecological Human Development, in which not only focuses on the context, but the interactions that the developing person keeps to him. This study aimed to verify the applicability of the software Desenvolve ® on cognitive assessment of children aged five to seven years on condition of institutional care, discussing the possibility of environmental arrangements and materials that will promote a healthy development. The participants were 16 children, aged from five to seven years, welcomed a Belém’s public host institution. To gather sociodemographic data sheet used the Ficha de Caracterização da Criança, that is a form consists of 94 items divided into five categories: identification of the child, family structure, history of institutionalization, sociojurídica current situation and child health, which were extracted the variables age, sex, education, reason for the host, length of stay in residential care, and educational evaluation. The cognitive assessment was performed by software Desenvolve ® that trough 127 screen measures the performance on 19 cognitive skills, which were analyzed in two categories: percentage of hits and misses¸ and percentage yield in each cognitive skill. The results reveal that the universe of participants is composed mostly of boys (75%), aged five years, family neglect the main reason for the reception. It is noteworthy also that 50% of participants go through their first experience of institutional care, while others face their second and third experiments on schooling has been that all children have started their school activities and / or develop in host institution’s Room Service Educational, however, there is a grace period for the medical records of educational evaluation. In cognitive assessment, for the category of percentage of hits and misses, has hit percentage greater than the errors for all children aged seven years, since the category of percentage of income in each cognitive skill stand out as cognitive skills of low income: perception of letters and numbers, perception timeline, naming numbers, sense of time, sense and perception of numerical sequence sequence. From these results, we propose a plan of environmental strategies and materials to promote healthy development, consisting of 12 strategies that encompass both activities aimed at (re) organization of the physical environment and the teachers of the institution, and to direct stimulation cognitive skills of lower income. Through the indicators of this study can observe the applicability software Desenvolve® for the assessment of children in situations of institutional care and the importance of this kind of mapping for the development and implementation of strategies that will promote and ratify the host institution as context promoter of healthy development.

An important aspect of intervention for people with autism based on Applied Behavior Analysis is that procedures should be used to reduce errors while learning a repertoire, considering the effects that errors may have on the learning process. Some studies have investigated the effects of correction procedure that requires active student response after the repetition of a trial with error. Some intervention manuals recommend do not reinforce answers corrected in the correction procedure with active response to prevent the establishment dependence of prompt used for correction. This study investigated the effect of reinforcement in an active-response correction procedure during the tact training in four children with autism. In an intra-participant design an echoic to tact training was made (initial training with simultaneous echoic prompt and then with a 3 s. delayed prompt) with adapted alternating treatment - one condition with reinforcement after corrections and the other condition unreinforced. All participants needed less correction trials in condition with reinforcement than in unreinforced correction condition, and participant‘s performance was superior in training condition with reinforcement after correction in nine of the twelve stimulus sets used in the study. We discuss the effectiveness of the reinforcement after the correction procedure, the absence of reinforcement dependence in this procedure, and the applied implications of the results.

(Universidade Federal do Pará, 2017-06-23) SILVA, Oriana Comesanha e; SOUZA, Carlos Barbosa Alves de; http://lattes.cnpq.br/1264063598919201
The ABLA-R (Assessment of Basic Learning Abilities Revised) is a useful test for assessing the discriminative abilities of individuals with autism and other developmental disorders. The studies that evaluated the teaching of the application of the most recent version of the test presented opposite results: indicating the efficacy of the test self-instructional manual or the need for additional training components. Furthermore, these studies did not evaluate the effect of feedback in training, or the effect of training in to teach professionals to apply ABLA-R. This study evaluated the effect of three training components on ABLA-R teaching for six professionals that working with people with developmental disorders: ABLA-R self-instructional manual, video feedback and role-play. Using a multiple probe design between pairs of participants, the efficacy of each component was evaluated separately and the efficiency of different combinations of these three components was evaluated. No component when used as the first training resulted in an accurate application of ABLA-R. In turn, the three training sequences of the three components used in the study proved to be effective in establishing accurate performance in applying the test to a confederate and a child with developmental disorder. The combination of the self-instructional manual with the video feedback resulted in the best performances. The importance of feedback for ABLA-R application training and ways to integrate manual and feedback use into more efficient forms of the test application training were discussed.

B. F. Skinner e o uso do controle aversivo: um estudo histórico-conceitual
(Universidade Federal do Pará, 2012-03-12) MARTINS, Tatiana Evandro Monteiro; MAYER, Paulo César Morales; http://lattes.cnpq.br/5360949596306254; CARVALHO NETO, Marcus Bentes de; http://lattes.cnpq.br/7613198431695463
B.F. Skinner (1904-1990) is frequently cited as having a contrary position on the use of aversive control. However, in certain passages Skinner presents a more flexible opinion about the use of this type of behavioral control. The purpose of the present study was identifying and analyzing the passages where Skinner prescribes or warns about such use. A historical-conceptual study was conducted involving eight Skinner works (Skinner 1938/1991, 1948/1975, 1953/1989, 1968/1972, 1969/1980, 1971, 1974/2006, 1989), analyzed according to the following categories: 1) the definition of aversive control and concepts involved; 2) the positive aspects of aversive control and prescribing; and 3) the negative aspects of aversive control and prohibitions. It wasn’t possible to find a specific definition of aversive control and it was observed that at certain moments Skinner justifies the use of aversive control, but does not prescribe it in general.

Caracterização do chamado de alarme de Dasyprocta sp. e Cuniculus paca (Rodentia, Caviomorpha) em cativeiro
(Universidade Federal do Pará, 2015-03-31) SILVA, João Gabriel Souza; SILVA, Maria Luisa da; http://lattes.cnpq.br/2101884291102108
The social mammal present complex and sophisticate vocal behavior, they are able to send and receive precise information about the environment and the interactions of the group. The order Rodentia, the biggest among mammals, has species that developed wide vocal repertoire in order to intermediate both interspecific and intraspecific relationships. During threatening context, some rodents emit specific vocalizations classified as alarm calls, these calls allow the perception of the threat and the possibility of subsequent reaction such as fight or scape. These reactions in the context of threat provide to these rodent species an effective defense against predation. In this context, we described and compared the acoustic parameter of the alarm call of the agouti (Dasyprocta sp.) and the lowland paca (Cuniculus paca) using the sonographic analysis of their vocalizations recorded in captivity. We realized the register of the agonistic calls of 16 individuals of Dasyprocta sp. and 6 individuals of C. paca in the vivarium placed in the Federal University of Para in a total of 85 minutes of recording. We recorded alarm calls during the social interactions that happened in their respective cages. The bioacoustics analysis of the 539 alarm calls of the agouti demonstrate that the frequency bandwidth varies from 224 to 978 Hz and the duration is 898 ms. The 95 alarm calls of the lowland paca analyzed presented frequency bandwidth that varied from 340 to 1280 Hz, the mean of the call’s duration was 1967 ms. The sound characteristics of these so called indicated that there is a predominance of lower frequencies of the acoustic signal of the two species, but the pacas can reach high and low frequencies much larger than the agoutis, and issue of longer duration signals. The principal components analysis (PCA) revealed that the alarm calls of both species are differentiated primarily by the maximum duration and frequency of the beeps.

The present study investigated personal characteristics, environmental and behavioral factors that may enable or impede/prevent the social interaction of children with ASD with their peers. Were analyzed the benefits of music education context as a promoter of this interaction. To organize the issuance of these forms of behavior, were elaborated the "Protocol observation of behaviors of children with Autism Spectrum Disorder (ASD) with their peers". The study investigated two children, male, diagnosed with ASD, of the Garden I, of the regular schools of the city of Belém/PA. The children were six and five years old, respectively, and were matriculated in percussion’ classes in Music’s School from Belem/PA. Three sessions were analyzed at regular school environment (during recreation), lasting 20 min each; and 8 sessions in the context of music education (lessons percussion), 30 minutes each. The results showed that the behaviors among children with ASD and their peers occurred in both contexts occurred in both contexts, however reaching higher frequency in the context free (regular school / recreation). As to the benefits of music education, The participant 1 (6 years), whose profile was marked by the acceptance of physical contact, and a search for persons, obtained the increase of functional initiative's behaviors and decreased of non-functional's responses. Observed it was also the occurrence of functional initiatives through repetitive behaviors, indicating that this peculiarity could do helping the child to approach and interact with peers. Already the participating 2 (5 years), with a profile marked by touch, emotional expression appropriate to the context, and social reciprocity (though occasionally), we observed a strong influence of the adult in the child's behavior. This influence was positive (to reduce the emission of non-functional behaviors) and negative (when had the high assist disregarding the child's strengths and hindering its interaction with peers). We conclude that given the low frequency of such behaviors, we cannot say that the changes are related exclusively to this environment, but only to the contiguity of the possibilities represented by the profile of the child and openness of each context for the expression and stimulation of these capabilities, as well as for the provision of tools to permit the seizure or reinforce behaviors conducive to social interaction.
