O Programa de Pós-Graduação em Teoria e Pesquisa do Comportamento (PPGTPC), que integra o Núcleo de Teoria e Pesquisa do Comportamento(NTPC) da Universidade Federal do Pará (UFPA), iniciou suas atividades em 1987 com o curso de Mestrado Acadêmico em Psicologia: Teoria e Pesquisa do Comportamento. O curso de Doutorado passou a ser oferecido a partir do ano 2000.

The objective of this study was to teach to three young adult capuchins, one male and two females, experimentaly naïve, conditional identity matching-to-sample (IDMTS) with four choices, identifying and producing Type S stimulus control topographies which may be favorable for stimulus-class formation. Behavioral persistence was analysed based on stimulus control topography coherence, behavioral momentum theories and on the studies conducted in the Experimental School for Primates. Participants were trained to touch stimuli projected in a computer touchscreen in an experimental chamber and were exposed to a procedure of: 1) Four-choice simple-simultaneous discrimination and shifts of discrimination procedure, with every other trial presenting only the S+, simulating the format of matchingto-sample; 2) IDMTS training with four samples and two or three choices, and the S+ in trial n was not presented as S- in trial n+1; 3) IDMTS training with four choices. Persistent responding in the simple discrimination shift training by M21 was eliminated when the former S+ n was not presented when a new stimulus became S+. The structural similarity between the simple discrimination and IDMTS sessions was not efficient to establish samplecontrolled responding. Subjects M18 and M21 eventually reach IDMTS performance; M20 received additional training with random ratio requirement for the response to the sample and is presenting gradual performance improvement.

Um programa de intervenção para o estabelecimento de escolha condicional por identidade ao modelo em um macaco-prego (Cebus apella)

The present study aimed to provide an adult male Capuchin-monkey with behavioral prerequisites for consistent performance in conditional identity matching-to-sample (IDMTS) tasks. The subject had problems in performing IDMTS probably due to adventitious development, during previous training of repeated reversals of simple discrimination, of stimulus control topographies incoherent with those needed for accurate performance in these tasks. The subject was presented with a remedial program designed to specifically develop appropriate topography of stimulus selection, and control for the relevant features of IDMTS tasks. The subject showed accurate conditional IDMTS performance with two stimulus sets after exposure to a non-conditional IDMTS procedure, in which there is no conflict in the control exerted by the stimuli serving as comparisons. Novel stimuli were presented in generalization tests, but no evidence of identity matching transfer was found. Explicit IDMTS training was then carried out with those stimuli, beginning with non-conditional IDMTS. When accuracy was again attained in conditional IDMTS, a new stimulus pair was substituted for the old, with no evidence of IDMTS transfer. Results suggest that the remedial program is effective in developing relational control by the sample stimulus. Some conditions for obtaining IDMTS transfer to new stimulus are discussed.
