1. Assessing restricted stimulus control in typically developing preschool children and bees (Melipona quadrifasciata)
This study established a simple simultaneous discrimination between a pair of two-element compound visual stimuli in children (Experiment 1) and bees (Melipona quadrifasciata, Experiment 2). The contingencies required discriminative control by the compound and the question was whether the accurate stimulus control reached at this level would hold for each in

2. Temporal control in chained fixed-ratio, fixed-interval schedules
Four rats were subjected to chained fixed-ratio (FR), fixed-interval (FI) schedules of reinforcement (chain FR 5 FI). A FR schedule at one lever produced a discriminative stimulus (i.e., light) associated with an FI schedule of primary reinforcement (water) at the second response lever. The FR schedule was kept constant, whereas the FI length was changed fro

3. Fixed-interval pause duration in chained fixed-ratio, fixed-interval schedules
Ten rats were submitted to chained fixed-ratio (FR), fixed-interval (FI) schedules of reinforcement. A FR schedule at one lever produced a discriminative stimulus associated with a FI 60-s schedule of primary reinforcement (water) at the second response lever. In Experiment 1, the FI schedule was kept constant while the FR requirement was changed from one to

4. Equivalência de estímulos em crianças portadoras da síndrome de apert / Stimulus equivalence in children with Apert Syndrome
The present study investigated the symbolic behaviors of patients with Apert Syndrome through the paradigm of stimulus equivalence, since it may provide a basis for understanding complex human behavior, such as symbolic behavior and language. It had been proposed three experiments which participants, aged between 16 and 21 years, were submitted to Experiment

5. Learning processes and the neural analysis of conditioning
Classical and operant conditioning principles, such as the behavioral discrepancy-derived assumption that reinforcement always selects antecedent stimulus and response relations, have been studied at the neural level, mainly by observing the strengthening of neuronal responses or synaptic connections. A review of the literature on the neural basis of behavio

6. Regra e criatividade no comportamentalismo radical de B.F. Skinner
Through a critical reading of Skinners works it was intended to clarify ambiguitiesconcerning scientific and philosophical communities regarding the concepts of rule and verbalstimulus. It was also sought an appropriate statement of creative behavior and thoughtconcepts according to Skinners Radical Behaviorism. This research had, therefore, a twofoldobjecti

7. Do antecedent conditions take part in metacontingencies? / Condições antecedentes participam de metacontingências?
A metacontingência é a unidade de análise no nível cultural proposta em analogia à tríplice contingência para explicar fenômenos sociais que envolvem a relação funcional entre contingências comportamentais entrelaçadas (CCE) e seu produto agregado e uma conseqüência cultural. Até o momento, as pesquisas experimentais investigaram o equivalente

8. Avaliação do tipo de resposta requerida e do procedimento de ensino no estabelecimento de controle de estímulos compostos
Several factors may influence behavior control by just one or all aspects of a multidimensional stimulus. The present study investigated the effects of the response required during discriminative training of compound stimuli. Six 4 years old kindergarten children participated. All children were exposed to 3 conditions of simple simultaneous discrimination tr

9. 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

10. Chronic stress and lives themes: a cognitive-behavioral purpose for conceptualization / Stress Crônico e temas de vida: uma proposta cognitivo-comportamental para conceitualização
The stress field has been studied so much where data have demonstrated that in average, more than half of the population of big cities present stress. Stress comes from inner factors (vulnerabilities) and outer ones (environment demands), however, when it is worked on the treatment area itself, it has been observed that some individuals present a sort of per

11. Resposta de observação e movimento dos olhos em uma situação de discriminação simples simultânea / Observing response and eye movement in a simultaneous simple discrimination situation
Previous studies draw attention to the importance of observing response to the discrimination establishment in differential reinforcement training. This research aims to analyze the observing response and eye movement in a simultaneous simple discrimination situation. Six adults participated. Images of Don Quixote screen painted by Pablo Picasso were used as

12. A participação de respostas de autodiscriminação em classes de estímulos equivalentes / Self-discriminated responses as members of equivalence stimulus classes
The purpose of this study was: (1) to establish the control of two (typing) responses as SD or conditional stimuli over a second response of choice between stimuli in a MTS task, (2) to verify if the typing responses became members of equivalent stimulus classes, and (3) if other stimuli of the equivalent classes would have discriminative functions similar t
