1. Orientação Parental para Insônia Infantil em Irmãos Gêmeos: Um Relato de Caso
Resumo A intervenção comportamental, por meio da orientação parental, vem alcançando resultados positivos no manejo da insônia em crianças. Contudo, questiona-se a efetividade de tais intervenções em irmãos gêmeos, pelo fato de os pais partilharem os cuidados de duas crianças da mesma idade e nível de desenvolvimento. O objetivo deste estudo é

2. Behavior and illusions: a model to study superstition in a participant replacement experiment
Abstract The notion of superstitious behavior can provide a basic background for understanding such notions as illusions and beliefs. The present study investigated the social mechanism of the transmission of superstitious behavior in an experiment that utilized participant replacement. The sample was composed of a total of 38 participants. Participants perf

3. New frontiers in the study of memory mechanisms
We review recent work on three major lines of memory research: a) the possible role of the protein kinase M-zeta (PKMzeta) in memory persistence; b) the processes of “synaptic tagging and capture” in memory formation; c) the modulation of extinction learning, widely used in the psychotherapy of fear memories under the name of “exposure therapy”.

4. A participação de diferentes sistemas neuromodulatórios no hipocampo, núcleo basolateral da amígdala e córtex pré-frontal ventromedial na extinção de memórias aversivas
Extinction consists of the learned inhibition of retrieval of previously acquired memory. Many forms of learning are modulated by ¿-noradrenergic, D1-dopaminergic and H2-histaminergic receptors on ventromedial prefrontal cortex (vmPFC), basolateral amygdala (BLA) and dorsal hippocampus. Therefore, the aim of this work was investigated the modulation of aver

5. Antidepressivos modificam a extinção de uma memória aversiva em ratas
Treatment of major depression, posttraumatic stress disorder and other psychopathologies with antidepressants can be associated with improvement of the cognitive deficits related to these disorders. Although the mechanisms of these effects are not completely elucidated, alterations in extinction of aversive memories are believed to be present in these psycho

6. 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

7. Pharmacological effects and behavioral interventions on memory consolidation and reconsolidation
In this article, we will review some behavioral, pharmacological and neurochemical studies from our laboratory on mice, which might contribute to our understanding of the complex processes of memory consolidation and reconsolidation. We discuss the post-training (memory consolidation) and post-reactivation (memory reconsolidation) effects of icv infusions of

8. Aplicações de mecânica estatística a especiação simpátrica e inferência aproximativa / Applications of statistical mechanics to sympatric speciation and aproximative inference
This thesis presents applications of the framework of Statistical Mechanics to two independent problems. The first corresponds to a computational model for the evolution of Assortative Mating in the Sympatric Speciation process; and the second a learning algorithm built by means of a Bayesian Inference approach. In the biological problem each individual in a

9. 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

10. Expressão de zif-268 durante a aquisição, evocação e extinção de uma memória aversiva
In the behavioral paradigm of discriminative avoidance task, both short and long-term memories have been extensively investigated with behavioral and pharmacological approaches. The aim of the present study was to evaluate, using the abovementioned model, the hippocampal expression of zif-268 - a calcium-dependent immediate early gene involved with synaptic

11. Educação pelos ritos de iniciação: contribuição da tradição cultural ma-sena ao currículo formal das escolas de Moçambique
The goal of this Dissertation is to analyze Education in Mozambique in the view of the Ma-Sena ethnic rites of initiation concerning learning to be, learning to live together, learning to know, and learning to do in community; as well as the Ma-Senas valuable contribution towards building-up socio-cultural identities in Mozambique. This paper also hopes to c

12. 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
