13. Organização temporal em processos de condicionamento classico aversivo e na expressão da proteina Zenk no hipocampo de pombos (C. livia) / Temporal organization of classical aversive conditioning processes and expression of Zenk protein in the hippocampus of pigeons (C. livia)
Part of the knowledge about the mechanisms and neural basis of learning, memory and amnesia is based on the investigation of neural correlates of the behavior of non human animals in aversive situations. Moreover, many studies suggest that these behavioral processes are affected by the circadian timing system. The procedures of classical aversive conditionin

14. Procedimentos aversivos : divergências entre as recomendações de Skinner e de Sidman e de psicoterapeutas infantis
Questionings reffering to the recommendation of intervention procedures are not recent, especially when it is argued regarding aversive procedures. The study that is described at this article has as main objective to verify the divergences between the recommendations of intervention procedures from training books for parents, recommended for child behavioral

15. Variabilidade induzida e operante sob contingências de reforçamento negativo / Induced and operant variability under negative reinforcement contingences
A variabilidade comportamental pode ser induzida por reforçamento parcial ou extinção, assim como pode ser reforçada diferencialmente. O objetivo deste estudo foi verificar como a variabilidade comportamental pode ser influenciada por estímulos aversivos, tanto no processo de indução por reforçamento parcial e extinção, como no reforçamento negati

16. Effects of aversive contingencies on lying behavior: Cues and detection. / Efeitos de contingências aversivas sobre o comportamento de mentir: Sinais e detecção
As a subdomain in the study of deception, lie detection deals with the investigation of variables that control changes on the behavior of senders while they tell lies (deception cues), and with the conditions under which detectors are capable of correctly identifying such cues. The present study investigated the effect of punishment of lying on deception cue

17. Extinção operante como procedimento aversivo: avaliação de seus efeitos com o Labirinto em Cruz Elevado
O presente estudo avaliou os efeitos da extinção operante, como um procedimento aversivo, sobre o percentual do tempo de permanência nos braços abertos de ratos no Labirinto em Cruz Elevado (LCE). Três grupos de sujeitos foram inicialmente expostos a diferentes condições (esquema de reforçamento em razão fixa RFR; acoplado RAC; e alimento maciço RA

18. The effects of variable interval schedule on preference and liquid consumption by rats subjected to chronic mild stress / Efeitos do esquema de intervalo variável na preferência e no consumo de líquidos apresentados por ratos submetidos ao chronic mild stress
The Chronic Mild Stress (CMS) is an experimental animal model of depression induced by the exposure of rats to a set of moderate and uncontrollable aversive stimuli in a long and uninterrupted period of time. The purpose of this study was to investigate the relationship between performance in variable interval schedule of behavior and exposure to the protoco

19. Análise da interação entre mãe e a criança durante o atendimento odontológico
A subject of great interest in Psychology applied to Dentistry is the explanation of the children s uncooperative behavior toward the dentist. About 25% of children are uncooperative, which can be understood by the presence of aversive events in the dental context. Children can tolerate these events when they set repertoire of self-control and of following r

20. Análise de possíveis efeitos desejáveis do controle aversivo na aprendizagem de comportamento eficaz
In this study, the hypothesis that contingences of punishment and negative reinforcement which constitute the area called ?aversive control?, take part in the process of establishment and maintenance of important behaviors, which can increase the probability of an individual to deal better with the adversities of his environment; as well as to contribute wit

21. Análise do livro "Coerção e suas implicações". de M. Sidman, 1995
In the present study, the book ?Coercion and its fallout?, from Murray Sidman, had been analyzed. Sidman (1989/1995) was concerned about showing: (a) the frequency that coercion occurs, which is defined for him like the use of negative reinforcement and punishment contingencies, (b) the unlike coercion?s effects and (c) indicate the use of procedures based o

22. AVALIAÇÃO COMPORTAMENTAL E FARMACOLÓGICA DA RELAÇÃO ENTRE ANSIEDADE E PÂNICO EM MODELOS ANIMAIS / BEHAVIORAL AND PHARMACOLOGICAL EVALUATION BETWEEN ANXIETY AND PANIC IN ANIMALS MODELS
The dorsal portion of the periaqueductal gray (DPAG) is notably associated with defensive behavior and panic attacks in humans. Electrical or pharmacological stimulation of the DPAG induces aversive reactions such as running and jumping in rats. Our results indicate that animals exposed to contextual cues, that were previously associated with electrical foot

23. Investigação longitudinal dos efeitos de diferentes contingências com estímulos apetitivos e aversivos sobre o desamparo aprendido / Longitudinal research on the effects of different contingencies with appetitive and aversive stimuli upon learned helplessness
The learned helplessness hypothesis was put forward by Seligman &Maier in 1976 under the assumption of generality among all stimulus conditions, aversive or otherwise, and as an explanatory model of human depression. This proposition allowed for some experimental manipulations aimed at reversing the effect, using, among others things, positive reinforcement

24. Response dependent and response independent environmental changes: a study on the effects of contiguity versus contingency / Alterações ambientais dependentes e independentes da resposta: uma investigação dos efeitos de contigüidade versus contingência
The effects of presenting stimuli that are well established as reinforcers independently of responding have been studied under two different perspectives. On the first perspective, through a procedure called accidentally reinforcement, stimuli are presented non-contingently, resulting in the accidental selection of a response, an effect called superstition.
