1. A influência da recompensa e da experiência na discriminação visual simultânea em sagüi comum (Callithrix jacchus)
A aprendizagem discriminatória é analisada através de tarefas instrumentais nas quais o indivíduo é recompensado por escolher um item ao invés de outro. Desse modo, na discriminação visual simultânea de objetos o animal deve aprender que somente um dos objetos será recompensado. A discriminação visual simultânea é relativamente simples, e já f

2. 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

3. Dissociation Between the Effects of Damage to Perirhinal Cortex and Area TE
Perirhinal cortex and area TE are immediately adjacent to each other in the temporal lobe and reciprocally interconnected. These areas are thought to lie at the interface between visual perception and visual memory, but it has been unclear what their separate contributions might be. In three experiments, monkeys with bilateral lesions of the perirhinal corte

4. Visual habit formation in monkeys with neurotoxic lesions of the ventrocaudal neostriatum
Visual habit formation in monkeys, assessed by concurrent visual discrimination learning with 24-h intertrial intervals (ITI), was found earlier to be impaired by removal of the inferior temporal visual area (TE) but not by removal of either the medial temporal lobe or inferior prefrontal convexity, two of TE's major projection targets. To assess the ro
