  • Maintenance of Discriminative Function Across Successive and Simultaneous Procedures

    Open AccessIsabelli J Callejão Sabino, Pedro Henrique Carvalho et al.ARTICLEThe Psychological Record2026

    Although simultaneous and successive discrimination procedures are both effective in establishing stimulus control, their direct comparison often suffers from procedural asymmetries. In this study, 10 undergraduate students were trained in simple discrimination tasks using either a simultaneous or successive format and tested for the maintenance of discriminative function by switching procedures. Half of the participants started with one procedur…

  • Emergent Reading of Japanese Hiragana via Stimulus Equivalence

    Open AccessPriscila Crispillho Grisante, Saory Miyakawa Morais et al.ARTICLEThe Psychological Record2026

    This study evaluated an experimental procedure for establishing an emergent reading repertoire of Japanese Hiragana (a nonalphabetic script) using the stimulus equivalence paradigm within a single-subject descriptive design. Three native Portuguese speakers were exposed to a matching-to-sample (MTS) procedure to establish conditional discriminations between dictated syllables (A), Hiragana characters (B), and their corresponding Romanized represe…

  • Molecular Analysis of Conditional Discriminations

    Open AccessAdriana Regina Rubio, Gerson Yukio TomanariARTICLEThe Psychological Record2026

    Whether the acquisition of conditional relations occurs simultaneously or sequentially is often obscured by global accuracy measures. The present study analyzed the acquisition of conditional discriminations in humans using a molecular, trial-by-trial approach. Three undergraduate students were trained on 12 visual conditional relations, divided into two sets (AB and BC), using an arbitrary zero-delay matching-to-sample (MTS) procedure. Results s…

  • Tracking Stimulus Control in an Arbitrary Matching-to-Sample Task Followed by Equivalence-Class Formation

  • Eye movements along the establishment of functional stimuli classes

    Open AccessNicolau Kuckartz Pergher, Edson Massayuki Huziwara et al.ARTICLEJournal of the Experimental…2025References: 28

    The present study analyzed the eye movement patterns of five typically developed adults who were exposed to a series of simple discrimination training tasks with reversals in the contingencies of reinforcement that led to the formation of functional stimulus classes. Two studies were planned. In Study 1, two visual stimuli were used to carry out one training phase and three consecutive reversals. In Study 2, the phases were repeated but four‐stim…

  • Patterns of eye movement in matching-to-sample tasks

    Open AccessEdson Massayuki Huziwara, Deisy G De Souza et al.ARTICLEPsicologia Reflexão e Crítica2016Cited by: 1References: 19

    The present study evaluated whether during a matching-to-sample procedure (MTS), the time spent observing stimuli is related to the establishment of selection or rejection controlling relationships in human participants. It also evaluated whether different response topographies (i.e., participants using the keyboard or mouse) would influence the duration of eye fixations. Ten college students participated. The procedure established conditional re…

  • Equivalência de Estímulos e Ciúme

    Open AccessVerônica Bender Haydu, Larissa Botelho Gaça et al.ARTICLEPsicologia Reflexão e Crítica2015

    A formação de classes de estímulos equivalentes tem sido usada como modelo experimental para investigar uma série de fenômenos comportamentais, tais como o desenvolvimento de comportamento simbólico e a transferência de funções que os eventos ambientais adquirem por meio de relações condicionais. O objetivo deste estudo consistiu em analisar o efeito de estímulos com alto grau afetivo pré-experimentalmente constituído, na formação de classes de e…

  • Analyzing the Stimulus Control Acquisition in Simple Discrimination Tasks through Eye Movement

    Open AccessEdson Massayuki Huziwara, Marcelo José Machado Silva et al.ARTICLEPsicologia Reflexão e Crítica2015Cited by: 1

    In order to investigate whether simultaneous or successive presentation of stimuli is related to the duration of eye fixation (i.e., the time spent gazing a specific stimulus), this study described the eye movements of young adults in simultaneous and successive simple discrimination tasks. Using 12 landscape scenes as visual stimuli, three participants were exposed to a simple discrimination training with simultaneously presented stimuli (Si Pro…

  • The Psychology Postgraduate System in Brazil

    Open AccessAntônio Virgílio Bittencourt Bastos, Gerson Yukio Tomanari et al.ARTICLEPsicologia Reflexão e Crítica2015

    This text is a characterization of the Psychology Postgraduate System in Brazil, presenting indicators of its growth in recent years, of its current geographical distribution, of its research lines, and of the grades awarded in the last Triennial evaluation of 2013. This characterization underlies a set of reflections regarding the challenges for the area from the guidelines established by the National Postgraduate System Plan (PNPG) 2011-2020. T…

  • Efeitos da exposição a estímulos aversivos e apetitivos incontroláveis sobre o comportamento verbal em contingências de reforço positivo

    Open AccessTatiany Honório Porto, Maria Beatriz Barreto Do Carmo et al.ARTICLEEstudos de Psicologia (Campinas)2011

    Foram analisados efeitos de diferentes histórias de incontrolabilidade por perda ou ganho de pontos sobre o desempenho posterior de participantes humanos na construção de frases. Inicialmente, os participantes podiam ganhar ou perder pontos independentemente de qualquer característica da frase construída. Posteriormente, recebiam pontos por construir frases iniciadas apenas pelo pronome "ele". Os resultados mostram que a exposição à incontrolabil…

  • Estímulo discriminativo de extinção produzido por respostas de observação em pombos

    Open AccessGerson Yukio TomanariARTICLEPsicologia Reflexão e Crítica2011

    Pombos privados de comida foram expostos a tentativas que podiam terminar com ou sem a apresentação de comida independentemente de qualquer resposta. Durante uma tentativa, bicadas podiam mudar a cor do disco de resposta de branco para verde (S+) ou vermelho (S-) a depender do acionamento (ou não) do comedouro. Em linha de base, bicadas produziam ambas as cores em intervalos médios variáveis de 15 s. Em duas condições experimentais distintas, tan…

  • Pesquisando ao ensinar

    Open AccessGerson Yukio Tomanari, Anamélia Araújo de Carvalho et al.ARTICLEEstudos de Psicologia (Campinas)2007

    No contexto de ensino da análise experimental do comportamento, 53 graduandos foram expostos à tarefa informatizada de construir frases. Iniciou-se o experimento com linha de base, na ausência de contingência experimental. A seguir, os participantes, em dois diferentes grupos, podiam ganhar (vs. manter) ou manter (vs. perder) pontos, segundo contingências programadas de reforçamento positivo ou negativo, respectivamente, aplicadas ao uso de um pr…
