1. Selección natural y condicionamiento de operantes: una crítica a la analogía de Fodor y Piattelli-Palmarini
ABSTRACTIn this paper I argue against the analogy between natural selection and operant conditioning that Fodor and Piattelli-Palmarini used to argue that the same arguments that discredit the behaviorist theory discredit the theory of natural selection. These theories are not independent either conceptually or historically and, therefore, it is unreasonable

2. Animal models of anxiety disorders and stress
Anxiety and stress-related disorders are severe psychiatric conditions that affect performance in daily tasks and represent a high cost to public health. The initial observation of Charles Darwin that animals and human beings share similar characteristics in the expression of emotion raise the possibility of studying the mechanisms of psychiatric disorders i

3. Discriminated conditioned suppression in rats
This experiment evaluated the effects of superimposing the Estes-Skinner Conditioned Emotional Response (CER) procedure on one of two components of a multiple schedule. The question was whether CER conditioning occurred under contextual control. The procedure had four experimental phases: (1) baseline of operant responding under a two-component multiple sche

4. Prenatal alcohol exposure did not affect impulsivity in rats that performed delay or probability discounting tasks
Individuals who fall under the spectrum of the Fetal Alcohol Syndrome have a higher prevalence of several cognitive disturbances, including a greater probability of being diagnosed with attention-deficit hyperactivity disorder (ADHD). Some of these effects, such as hyperactivity and attentional impairments, are already well established in the literature. The

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. Laboratórios de análise do comportamento no Brasil: percursos na UFMG na década de 1970
This work presents a historical narrative about the Behavior Analysis laboratories in Brazil, particularly those of Universidade Federal de Minas Gerais (UFMG). Due to Behavior Analysis impact on UFMG in the 70´s, the investigated period was from 1969 to 1981. The main object of this study was the operant conditioning chamber. The chamber, as a scientific i

7. Operant serial feature-positive conditional discrimination with composite features and different topography responses
In a serial feature-positive conditional discrimination procedure the properties of a target stimulus A are defined by the presence or not of a feature stimulus X preceding it. In the present experiment, composite features preceded targets associated with two different topography operant responses (right and left bar pressing); matching and non-matching-to-s

8. Influence of environmental enrichment in alcohol oral self-administration in rats / Efeito de enriquecimento ambiental na auto-administração oral de álcool em ratos
Esta pesquisa estuda a relação entre o ambiente em que ratos se desenvolvem e a auto-administração de etanol (ET) na idade adulta. Usualmente, a pesquisa comportamental com animais em laboratório utiliza sujeitos mantidos em isolamento em caixas individuasi (I). Uma das espécies mais usadas é o rato, um animal social que em habitat natural vive em col

9. The Concept of anxiety in Behavior analysis / O Conceito de ansiedade na análise do comportamento
Issues concerning to anxiety have been discussed in Psychology focusing several different aspects, but definitions of anxiety are far from consensual. The difficulty is due to several reasons, among which is the lack of a precise reference to behavioral relations. Divergence is also found in behavior-analytic literature. Some accounts stress the role of dire

10. Princípios de condicionamento à luz da análise neural do estímulo antecedente / Principles of conditioning in light of the neural analysis of the antecedent stimulus
A participação de estímulos e respostas em contingências não depende de sua origem interna ou externa. O ponto relevante é que a natureza funcional dos termos da contingência baseie-se em leis comportamentais. Nesse sentido, eventos neurais são também comportamentais, e assim podem permitir a observação de mecanismos básicos da aprendizagem. No p

11. Evaluation of the change in amplitude of the electromyographic potential of the quadriceps through the biofeedback effect using surface electromyography in patients with spinal cord injury / "Avaliação da alteração da amplitude do potencial aletromiográfico do quadríceps pelo efeito da retroalimentação por eletromiografia de superfície em pacientes com traumatismo raquimedular"
Electromyography biofeedback is a learning technique for voluntary control of physiological responses through operant conditioning. The electromyographic signals from the quadriceps muscles of two biofeedback series were compared using the Brucker method, with a 50-minute weekly session during four weeks and a three-month interval, in 20 patients with cervic

12. The Operant and the Classical in Conditioned Orientation of Drosophila melanogaster at the Flight Simulator
Ever since learning and memory have been studied experimentally, the relationship between operant and classical conditioning has been controversial. Operant conditioning is any form of conditioning that essentially depends on the animal's behavior. It relies on operant behavior. A motor output is called operant if it controls a sensory variable. The Drosophi
