1. Blank-comparison matching-to-sample reveals a false positive symmetry test in a capuchin monkey
A positive symmetry test result was obtained with a capuchin monkey that had previously exhibited virtually errorless AB and BA arbitrary matching-to-sample (MTS) with different stimuli. The symmetry test (BA) followed the acquisition of a new AB relation. It seemed possible, however, that the positive result could have occurred through the exclusion of prev

2. Electrophysiological investigation of the functional overlap between semantic and equivalence relations
Recent research using the event-related potential (ERP) technique has shown that equivalence relations have properties similar to genuine semantic relations. This study aimed to advance electrophysiological investigations of the functional overlap between semantic and equivalence relations. The N400 component, an index of semantic processing, was used to mea

3. Overtraining increases the strength of equivalence relations
The present study investigated whether overtraining of the conditional discriminations that are the prerequisites of equivalence class formation strengthens the relations among stimuli in an equivalence class. Two groups of college students formed equivalence classes that consisted of faces that expressed emotions (A) and arbitrary stimuli (B, C, D, and E).

4. Restricted stimulus control in stimulus control shaping with a capuchin monkey
Teaching the first instances of arbitrary matching-to-sample to nonhumans can prove difficult and time consuming. Stimulus control relations may develop that differ from those intended by the experimenter-even when stimulus control shaping procedures are used. We present, in this study, efforts to identify sources of shaping program failure with a capuchin m

5. Efeito do ensino de palavras monossilábicas via treino de relações condicionais arbitrárias sobre o controle por unidades mínimas em leitura recombinativa / Effect of teaching monosyllabic words via arbitrary conditional relations on the minimal control units in recombinative reading
O procedimento de discriminação condicional Matching - to - Sample é utilizado em estudos que se propõem a investigar experimentalmente as relações envolvidas no ler e, mais especificamente, de verificar as possibilidades de emergência de novas relações a partir das que foram diretamente treinadas . No entanto, para uma leitura proficiente é necess

6. Condições que favorecem ou desfavorecem a aprendizagem relacional em crianças com histórico de fracasso escolar
The stimulus equivalence concept has been used by behavior analysts as an instrument to systematic verifications of new and complex repertories, offering an operational specification of symbolic behavior and distinguishing between two kinds of relational stimulus pairs: conditional relations and equivalence relations. The most often used procedure to verify

7. Investigação de propriedades quantitativas de relações simbólicas em quatro estudos experimentais envolvendo o paradigma de equivalência de estímulos
This work presents four experimental studies that evaluated transfer of functions from faces expressing emotions to arbitrary figures equivalent to them. The specific goals of each study can be articulated around a proposal to investigate quantitative properties of equivalence relations. Chapter 1 describes an experiment conducted to examine if the level of

8. Desempenhos emergentes e leitura funcional em crianças com transtornos do espectro autístico
People with autism display a number of marked deficits in communication, symbolic or imaginative activities, reciprocal social interaction and the presence of a pattern of restrict behavior. Follow-up studies indicate that people with autism show difficulties in learning relationships between stimulus through conventional interventions. The first study asses

9. Formação de classes de equivalência através de reforçamento específico em crianças com dificuldades de aprendizagem. / Equivalence class formation through specific reinforcement in children with learning difficulties
In Behavior Analysis, several studies have been carried out in order to understand how behavior can be productively controlled by arbitrarily related events, through equivalence class formation. The inclusion of reinforcer stimuli in the classes has been pointed as a possible facilitator of their formation. The present study aimed to evaluate the formation o

10. The establishment of errorless simple discrimination with letters and its rotations: the effects in identity and arbitrary matching / A promoção de discriminação simples, sem erro, de letras e suas inversões: seus efeitos em testes de matching de identidade e arbitrário
No presente trabalho um procedimento de discriminação simples simultânea sem erro - dica atrasada - entre pares de letras graficamente semelhantes e suas inversões. Testou-se também os possíveis efeitos do treino discriminativo em tentativas de emparelhamento de acordo com o modelo (matching to sample) de identidade e arbitrário em que as letras que p

11. Escolha de acordo com o modelo: relações emergentes entre estímulos arbitrários em indivíduos de diferentes condições de peso corpóreo / Matching-to-Sample: emerging relations between arbitrary stimuli in individuals of different conditions of body weight
The objective of this project was to investigate if the stimuli Equivalence model can describe part of the obesity problem related to the external control of stimuli. Six subjects, three with IMC<24.9Kg/m2 and three with IMC >24.9 were exposed twice to a same choice procedure in accordance with the model that utilized a set of non-food stimuli in the first s

12. Ensino de discriminações condicionais por imitação: efeitos de dois arranjos de apresentação de tentativas.
Imitation can be defined, in general terms, as the similarity of behavior between two organisms when the response topography of one, the imitator, is similar to nd controlled by the behavior of the other, the demonstrator. Along the years there has been a lot of controversies involving imitation`s conceptualizations and discussions on how it is produced and
