1. 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

2. Cebus cf. apella exhibits rapid acquisition of complex stimulus relations and emergent performance by exclusion
A "second generation" matching-to-sample procedure that minimizes past sources of artifacts involves (1) successive discrimination between sample stimuli, (2) stimulus displays ranging from four to 16 comparisons, (3) variable stimulus locations to avoid unwanted stimulus-location control, and (4) high accuracy levels (e.g., 90% correct on a 16-choice task i

3. Discrimination of complex visual stimuli in Cebus apella: identity matching with pictures
Do capuchin monkeys respond to photos as icons? Do they discriminate photos of capuchin monkeys' faces? Looking for answers to these questions we trained three capuchin monkeys in simple and conditional discrimination tasks and tested the discriminations when comparison stimuli were partially covered. Three capuchin monkeys experienced in simultaneous simple

4. Sucessive shifts of simple discrimination in infants / Discriminação simples com mudanças sucessivas na função dos estímulos em bebês
This study investigated with three infants, 10 to 14 months-old at the beginning of the experiment, the acquisition of successive shifts of simple discrimination (SSSD), considering that this repertoire can facilitate the identity matching-to-sample (IDMTS) learning, a potential prerequisite for the development of more complex symbolic repertoires. The task

5. Procedures to produce and identify stimulus control relations in identity matching-to-sample tasks with Cebus apella / Procedimentos para determinação e identificação de relações de controle em tarefas de IDMTS em Cebus apella
Obtaining Type S and Type R control relations in Identity MTS (IDMTS) tasks may make possible the development of an accurate observing repertoire towards all the stimuli (S+ and S-). In this work, a sequence of procedures was used to generate or identify possible stimulus control relations present in IDMTS training and tests. The purposes of the present work

6. 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

7. Effects of simple discrimination training on identity match-to-sample performance of an capuchin monkey (Cebus apella) / Efeito do treino de discriminações simples sobre o repertório de pareamento ao modelo por identidade de um macaco-prego (Cebus apella)
This paper reports an experiment training to verify the function of simple simultaneous discrimination training with pairs of stimuli on identity match-to-sample performance with the same stimuli. An infant capuchin monkey with experience with identity match-to-sample served as subject. It was investigated how much training with a Repeated Shift of Simple Di

8. Contribuições para o controle experimental na aprendizagem de discriminações por bebês.
The literature has emphasized the necessary investigation of the variables acting in conditional discrimination learning for infants in experimental and natural situations. Part of the challenge in reaching the research goals with this population lies in the difficulties of dealing with young children during experimental situations, controlling the presence

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. The establishment of stimulus control over pairs of graphically similar letters and syllables: A comparison among trial and error, fading and stimulus shaping / Uma comparação entre procedimentos de estabelecimento de controle de estímulos entre pares de letras com grafias semelhantes e no reconhecimento de sílabas: tentativa e erro, fading e shaping de estímulos
The purpose of this study was to compare 3 procedures to establish stimulus control between graphically similar letters. The participants were 12 non literate children, ages 2 to 6.The children were first exposed to an identity matching to sample test with letters. Then, they were randomly assigned to 1 of 3 simple discrimination training procedures: trial a

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
