(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.

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.

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.

Aplicação de tentativas discretas por cuidadores para o ensino de habilidades verbais a crianças diagnosticadas com autismo
(Universidade Federal do Pará, 2015-08-25) SILVA, Álvaro Júnior Melo e; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024
The cases of Autism Spectrum Disorder (ASD) are characterized by persistent deficits in communication and social interaction in multiple contexts. The diagnosis of ASD also involves the presence of repetitive behavior and restricted interests. Considering the need of intervention and the lack of qualified professionals to implement intervention the purpose of this study was to verify the effects of parent-implemented teaching programs (VI) on the performance of children (VD). Participants included three children diagnosed with autism and their respective caregivers. Through a multiple probe design, the independent variable (IV) was selectively implemented on each of the teaching programs. Caregivers carried out the intervention at home and had their performance, and the performance of their children, was evaluated in sessions conducted in the room of the APRENDE Project/UFPA. Their performance was monitored during every session. Two or more programs were selected for each child. Participant 1 reached criterion for performance accuracy in the following programs: "Tact of Actions", "Mand with Autoclitic", and "Intraverbal of Personal Informations" after 7, 13, 19 sessions, respectively. Participant 2 needed 24 to 48 sessions and the Participant 3, 5 to 38 sessions to achieve accuracy in the programs. Data show that the intervention via caregiver, guided by a behavior analyst, can be effective and appropriate to the social-economic context of Brazil, characterized by lack of governm.

Aprendizagem observacional em crianças com autismo: efeitos do ensino de respostas de monitoramento via videomodelação
(Universidade Federal do Pará, 2015-07-22) BRASILIENSE, Izabel Cristina da Silva; SOUZA, Carlos Barbosa Alves de; http://lattes.cnpq.br/1264063598919201
Has been pointed that video-modeling seems to promote the observational learning in individuals with Autism, included verbal repertories. However individuals with Autism often exhibit difficulty to learn by observing the actions of others. One method to provide observational learning it is previous training of monitoring pair’s actions. Nevertheless, monitoring training studies has been accomplished in-vivo pairs, making them more expensive and committing experimental control. This study investigated the possibility of establishing monitoring response via video-modeling. Furthermore, investigated if observational learning of tacts and textual could emerge by acquisition of monitoring repertory. Two children with autism participated. Observational learning tests via video-modeling were performed. Then the tact monitoring training via videomodeling was implemented in three steps: (1) teaching of monitoring behavior; (2) attempt to the model’s responses and (3) attempt to the model’s response consequence, not knowing the objects’ tacts. Afterwards, tests for tacts and textual were conducted via video-modeling. Two children acquire monitoring repertory in four sessions, indicating that monitoring training via video-modeling can be an effective and economic alternative for monitoring training. The acquisition of monitoring repertory beneficed the acquisition of tact and textual via observational learning for one of the participants. It is discussed the potential effects of video-modeling to train precurrent behaviors necessary for observational learning and the necessity of continuing researchxii in this area for better comprehension of variables that influence the acquisition of observational learning.

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.

The Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) is a criteria-based assessment tool that can be used as a curriculum guide and repertoire development monitoring system for children with autism and other developmental disorders. The three levels of VB-MAPP were established from typical child development milestones derived primarily from studies with US or European children. Considering the socioeconomic and cultural differences that exist between the United States/Europe and Brazil, this study analyzed the adequacy of VB-MAPP functional levels for the evaluation of verbal, social and motor repertoires of a sample of 61 Brazilian children with typical development, living in Belém do Pará, of both sexes and aged between one and five years. The results showed that the functional levels proposed in the VB-MAPP were adequate to evaluate repertoires of a sample of Brazilian children with typical development, increasing the data on the external validity of the instrument. Based on these results it is suggested the relevance of the use of VB-MAPP in the Brazilian context.

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 de um procedimento de aproximação sucessiva sobre a seleção de uma prática cultural complexa
(Universidade Federal do Pará, 2013-09-23) PAVANELLI, Sergio; TOURINHO, Emmanuel Zagury; http://lattes.cnpq.br/5960137946576592
The investigation of cultural selection has become more consistent theoretically and empirically in the Behavior Analysis especially after Sigrid S. Glenn proposed and developes the concept of metacontingencies. At the level reached by empirical investigations, a challenging issue relates to the complexity that cultural phenomena usually present. Cavalcanti (2012) evaluated the possibility of increasing the probability of complex interlocked behavioral contingencies (IBCs) by means of a successive approximation procedure (analogous to modeling operant response) involving a task of choosing rows of a matrix by group members. This study was conducted at the Laboratory of Social Behavior and Cultural Selection of this University (LACS / UFPA) and consisted of a replication with two microcultures, of Cavalcanti's first experiment with addition of the following changes in the procedure: a) introduction of generational change, b) steady order of choice by members of the lineages in the microculture and c) The use of two sets of criteria for the production of cultural consequence (one with each microculture). Study participants were undergraduate students from various courses, excluding psychology, distributed in two microcultures (A and B) consisting of 4 participants positioned in 4 different lines (L1, L2, L3 and L4). In each microculture 4 participants worked simultaneously sending individual responses (choice of lines in a 10x10 matrix) which produced individual consequences (exchangeable chips for money) every time the operant contingencies in place (choice of odd lines) were met. Regardless of operant contingencies was also the release of reinforcing cultural consequence in the form of figures stamped on a card which were exchanged for school items to make up a kit at the end of the experiment. The experimental session consisted of cycles of attempts (moves made by the microcultures) and generations of participants. Each generation corresponded equivalent to 20 cycles of trying. In each generation a new participant was inserted to replace the one with more time in the study. Substitutions made occurred within each specific strain. The general objective of the study was to evaluate the effects of the gradual increase in environmental complexity procedure (criteria required for the production of cultural consequences) on the "modeling" of cultural practices in the context of sucessive generations. For the two microcultures data suggest the efficacy of the procedure of gradual increase in environmental complexity in the production of complex IBCs and provide greater generality to the results found by Cavalcanti. However, the study provided no comparison of microcultures exposed of gradually increasing complexity with continued exposure of a microculture to the more complex environment. For this reason, it is clear that the procedure analogous to modeling was effective in producing complex IBCs, but not that it was more effective than the continuous exposure of a microculture, for the same number of cycles, to the more complex environment.

The literature on Behavior Analysis may contribute to the educational system, despite the little influence exerted in pedagogical practice. The performance of the students is functionally related to that of the teacher, making important the investment in professional training. The Lemov taxonomy cataloged teaching techniques based on the behaviors of teachers with students with excellent academic performance, presenting similarity with the behavioral perspective. The objective of this study was to evaluate the training of Lemov taxonomy techniques with four elementary school teachers. A pre and post-training record was made of the occurrences of the techniques in the classroom, and trained the techniques ‘No opt out’ and ‘Stretch it’, containing booklets and role-play with feedback, components of behavioral skills training. After intervention there were few occurrences of the trained techniques, but there was an increase in related techniques, indicating a partial effect on teachers’ behaviors. The need for in situ training, modeling and simplification of training criteria are discussed.

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.

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.

One of the most serious complications of diabetes mellitus (DM) is neuropathy that affects the skin sensitivity, causing decreased or even absent, facilitating the development of diabetic foot. Such complications can be reduced with adherence to treatment rules of foot care for diabetic patients. Therefore, this study aimed to evaluate the effects of rules, justifications for tracking and social reinforcement, and also compare the effects of a questionnaire (Questionnaire 2 - Q2) specifying the behavior of foot care with effect from another questionnaire ( Questionnaire 1 - Q1) without specifying such behaviors in six diabetic adults through the following instruments: Interview Script Initial Script Initial Questions, Observation Protocol feet, Questionnaire 2 - List of Behaviors Care Feet, Quiz 1 - Protocol Questions about Behavior Care Feet, Rules and Foot Care Rules with Additional Justifications for Foot Care. Seven meetings were held weekly, in which participants were exposed to procedure A (Baseline [Q2] - Q1 - Q2) and procedure B (Baseline [Q1] - Q2 - Q1) in Conditions 1 (social reinforcement), 2 (justification) and 3 (without social reinforcement / without justification). The results showed that half of the participants reported receiving no guidance foot care, four of the six had anatomical deformities in the feet, all had some aspect circulatory and dermatological, and only one participant wearing proper footwear. Terms of reported behaviors of foot care, it was found that participants exposed to Q2 (P11a, P21a and P31a) had a larger number of reports than participants exposed to Q1 (P12b, P22b and P32b). However, there is clear evidence in this study, treatment adherence. One fact that supports this assertion is the fact that the number of reported behaviors of foot care, participants presented P11a, P21a and P31a have decreased when these participants were exposed to Q1.

The present study was to develop a methodology for monitoring capacitating actions in a federal educational institution. The study was carried out at the Pro-rectory of Development and Management of Personnel with 26 technical-administrative public workers. We used the 360º type performance evaluation, in which the public worker performs self-evaluation and also is evaluated by different organizational actors. The procedure comprised: mapping the competences, establishing performance indicators, validating indicators, and implementation of the evaluation questionnaire. The results showed that the proposed methodology has adequate scale items that make possible an objective evaluation of the worker performance. Therefore, the new methodology was considered as a promising tool for the development of public workers and the process of competence decomposition was effective to create evaluation indicators.

The expectation of the cochlear implant (CI) user is recovering auditory sensitivity and understands spoken language. Considering the auditory rehabilitation as a prerequisite for the development of language skills, the aim of this study was to investigate the effect of training on the behavior of the listener to speaker in this group, check the emergence of relationships and the generalization to indirectly taught voice different frequency. Participated of the study three adults with profound, bilateral, neurosensory hearing, loss post-lingual, CI users, with time deprivation (TD) ranging from 5 months to 23 years. Data were collected with a computer with touch screen and application programming routines for the teaching and testing. The teaching program, with seven stages, had choice according to the model. Phase 1) Pre-train for habituation, the participant with auditory-visual tasks by fading out, 2) Pre-test naming and reading, to select 8 words for training, 3) Training of relations between dictated words and figures; 4) Training of relations between dictated words and written words; 5) Testing equivalence class, which were not directly taught; 6) generalization testing, with the dictated words, with an adult male voice; 7) Post-test of picture naming and word reading. Two of the three participants learned the tasks (Phases 3 and 4), and showed equivalence class (Phase 5) e generalization (Phase 6). All of the participants improved their ability of speaking after the study (Phase 7). The performance of the participant with 23 years of TD, which presented difficulties in oral language, was low, indicating further investigation of the variables due to flaw on the training, or to the IC operation, or inappropriate use of the device, etc. More studies are required to evaluate the potential of the procedure adopted for the auditory rehabilitation of CI users.

The acquisition of generalized discriminative relational repertoires represents a complex discriminative capability in the interaction on any species with its environment, having, for much time, being considered to be exclusively human. There are few researches on this capability in non-human primates in the auditory modality, and even less about their multimodal discriminatory repertoire, which characterizes much of the complex discriminative human behavior. This study investigated the possibility of a capuchin monkey (Cebus apella) to learn to respond appropriately to different acoustic stimuli by the use of a simple discrimination procedure. The subject was exposed to five pairs acoustic stimuli: each pair was always composed of one sound with a predominance of high frequencies and another of low frequencies; one of them with a function of positive stimulus (S +) and the other of negative stimulus (S-). The criteria adopted for the presentation of a new pair of stimuli was the achievement of a rate of response for the (S-) equal of inferior more than 25% of the rate for the (S +), for five consecutive sessions. The subject reached the criteria for all five pairs of stimuli. The effects of learning set and the physical properties of the stimuli are discussed, as well as procedural differences in regard to previous studies. These results suggest the possibility of using capuchin monkey as an animal model in research on complex discriminative repertoires.

Discriminações auditivo-visuais e a emergência de tatos em crianças com Transtorno do Espectro Autista: uma replicação sistemática
(Universidade Federal do Pará, 2021-09-08) CARVALHO, Rhayssa Fernandes da Silva; SILVA, Flávia Teresa Neves; http://lattes.cnpq.br/9875105389453993; SOUZA, Carlos Barbosa Alves de; http://lattes.cnpq.br/1264063598919201
Establishing auditory-visual conditional discriminations is a key step in protocols for teaching children with Autism Spectrum Disorder (ASD). However, there is a variety of procedures that have been used for teaching this repertoire. Recently, Fisher et al. (2019) showed that procedure package (which included 'conditional only' discriminative training, use of echoic response as a differential observation response, identity-match prompt with progressive delay, and error correction) favored the learning of auditory-visual discriminations in four children with ASD, and the emergence of tacts of the visual stimuli for two of them. The present study performed a systematic replication of Fisher et al. (2019), removing initially the requirement for echoic responses from the procedure package, in order to evaluate the role of this component in the acquisition of auditory-visual discriminations and tacts in children with ASD. A multiple baseline across stimuli design was used. The results showed that echoic response requirement was necessary for the participants to learn most of the auditory-visual discriminations, and that two participants presented emergence of tacts to some of the visual stimuli. The procedure package efficiency on teaching listener responses, possible treatments interference effects, component analysis, and the role of echoic on the emergence of tacts are discussed.

Resurgence is the behavioral phenomenon of reappearance of a target response, previously extinguished, after devaluation of an alternative. Traditionally, the alternative response has its maintenance conditions changed by extinction procedures, however, little is known about the effects of using other devaluation procedures such as timeout, a form of negative punishment used in applied situations. The present work aimed to evaluate the effect of punishing the alternative response with timeout on the resurgence of the behavior. Two four-phase experiments were performed. Experiment 1: In Phase 1, a target response was reinforced in a 10 s VI. In Phase 2, the target response was extinguished while an alternative response began to produce reinforcers in a VI 10 s. In Phase 3, a timeout contingency (50 s) was superimposed on the reinforcement contingency in force. In Phase 4, both responses were extinguished. Experiment 2: phases 1, 2 and 4 were similar to those of Experiment 1, with the only difference being that the sessions started with a blackout period and had a reduced timein time from the end of phase 2. In phase 3, a timeout contingency (30 s) was superimposed on the alternative reinforcement. The results indicated that the timeout devalued the alternative option in both experiments and induced resurgence for all (Experiment 1) and the majority (Experiment 2) of the subjects. Possible variables that may have led to these results are discussed.

Efeito de consequências culturais de naturezas diferentes sobre um culturante
(Universidade Federal do Pará, 2018-01-05) PAIXÃO JUNIOR, Francisco Denilson; TOURINHO, Emmanuel Zagury; http://lattes.cnpq.br/5960137946576592
The concept of metacontingency describes functional relations between interlocking contingencies (with their aggregate products) and cultural contingencies. We call culturant the recurrent unit of interlocking behavioral contingencies and their aggregate products. For more than a decade ago, behavior analysts have been dedicated to make the experimental evaluation of metacontingency’s relations. Current studies verified that verbal cultural consequences correlated with non-verbal cultural consequences produce more rate of recurrence of culturants than just cultural consequences of one nature only. However, the differential effects of cultural consequences dependent of the changes in experimental condiction on a culturant are unknown. This study evaluated the differential effect of cultural consequences of different natures (correlated or not) on a target culturant from an experimental preparation that applied an analogous ABAB single-subject design in a task of choosing color lines in a matrix. The dates suggests that there are more favorable conditions for the selection and maintenance of culturants than others and that stereotyped patterns of choices emerge under conditions of high stability of culturant recurrence. This study also has light on possibilities of studies related to uncontrollable aversive conditions and their effects on culturante.
