1. Desamparo aprendido e imunização em humanos: avaliação metodológica/conceitual e uma proposta experimental / Learned helplessness and immunization in humans: methodological/conceptual evaluation and an experimental proposal
The results of learned helplessness studies with humans have been inconsistent. This is probably due to the systematic contiguity between the end of the aversive stimulus and the immediately preceding response during the uncontrollability session, which mimics an accidental control condition. Three experiments were conducted to establish a procedure with ade

2. Comportamento verbalmente controlado: uma análise do efeito de operantes verbais autoclíticos sobre o comportamento de escolha / Verbally governed behavior: an analysis of the effects of autoclitic verbal operants upon choice behavior
The present study aimed to investigate the effect of verbal descriptions with or without autoclitic operants, upon the performance of adult participants in a choice task. To achieve it, a concurrent schedule design was planned, in which it was observed the preference pattern of each participant between the alternative of smaller and immediate reinforcement o

3. Olfactory Learning in Individually Assayed Drosophila Larvae
Insect and mammalian olfactory systems are strikingly similar. Therefore, Drosophila can be used as a simple model for olfaction and olfactory learning. The brain of adult Drosophila, however, is still complex. We therefore chose to work on the larva with its yet simpler but adult-like olfactory system and provide evidence for olfactory learning in indiv

4. Combined Antecedent Variables as Motivating operations within Functional Analyses
Functional analysis test conditions typically manipulate a single antecedent variable and an associated consequence to better isolate response–reinforcer relations. In some instances no problem behavior is observed, perhaps representing a false-negative finding. The present study evaluated one approach to assess potentially false-negative findings within f

5. A Test Of The Formal And Modern Theories Of Matching
The present study tested a formal, or purely mathematical, theory of matching, and a modern account derived by McDowell (1986) that incorporates deviations from strict matching—bias and sensitivity. Six humans pressed a lever for monetary reinforcers on five concurrent variable interval (VI) schedules of reinforcement. All schedules were presented during e
