2. Behavioral, affective, and cognitive alterations induced by individual and combined environmental stressors in rats
Objective: To evaluate whether exposing rats to individual or combined environmental stressors triggers endophenotypes related to mood and anxiety disorders, and whether this effect depends on the nature of the behavior (i.e., innate or learned). Methods: We conducted a three-phase experimental protocol. In phase I (baseline), animals subjected to mixed sc

3. Correspondência fazer-dizer : variáveis de controle e condições de manutenção e generalização / Doing-saying correspondence: controlling variables and maintenance and generalization conditions.
The present proposal is based on the assumption that verbal responding is an operant behavior established and maintained by reinforcement contingencies. Study 1 evaluated the effects of three different correspondence training methods on the maintenance of eleven childrens accurate self-report. Doing consisted of reading aloud a written word presented on a co

4. 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. Efeitos de construção de história relativa aos estudos de variação e repetição
The variability produced from contingent reinforcement to change and / or repetition of responses has been investigated in behavior analysis. Despite the variability of behavior have made it the object of working study in operant literature, there are few studies which demonstrates the introduction of a baseline for evaluating the effects of manipulation of

8. Variação induzida por quebra da relação de contingência: efeitos de regras e da suspensão do reforçamento
The study of the selective function of reinforcement has been prevailing in studies about operant behavior and just recently in the behavioral variation, a condition without which the selective function of the reinforcement doesn t have as operating, it has started to be more studied experimental and conceptually. These studies are divided into studies about

9. Experimental analogous of social phenomena: the effects of the cultural consequences / Análogos experimentais de evolução cultural: o efeito das conseqüências culturais
To many behavior analysts, the concern about social phenomena has been subject of research and discussion. Some of these researchers have been devoted to intervention in the contents generated by these phenomena, while the other part dedicates to formulation of principles which describes the behavioral processes in a cultural level. This work fits in the sec

10. 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

11. Identificação de relações de metacontingências e macrocontingências, conforme os critérios propostos por Malott e Glenn (2006)
Often, the environment that has a behavioral function for us is the behavior of others (Glenn, 1991). This means that there is a similarity between the behavior s content of different individuals, characterizing a cultural practice (Glenn, 2004). The concepts of macrocontingência, and metacontingência characterize the contingencie s relation contained in t

12. Robotic architecture inpired from Behavior analysis / Arquitetura robótica inspirada na análise do comportamento
Sociable robots should be able to interact, to communicate, to understand and to relate with human beings in a natural way. There are several scientific and practical motivations for developing sociable robots as platform of researches, education and entertainment. However, although several sociable robots have already been developed with success, much work
