Atenção temporal e análise da interferência da característica do estímulo na percepção

Attention is a phenomenon that allows the selection of relevant stimuli in order to prioritize them and improve their processing. This modulation could occur in any step of the process: in an early stage or in a late stage, more precisely, in a perceptive or motor stage. However, even with a rich literature about attention in time, there are still some divergences about how this modulation occurs. A hypothesis about it says that temporal attention would only be able to prepare the motor system to respond. The perceptual modulation would only occur when the temporal expectation is in combination with another expectation of a property with neuronal receptive field. In this situation, the receptive field's pre-activation is the explanation of how temporal attention would be capable to modulate perceptual process. The crucial objective was to test this hypothesis. In other words, it was to verify if the feature expectation of a stimulus (Gabor orientation) and its temporal expectancy interferes in perception quality. Two experiments were made: the first one tested the voluntary temporal expectation, and the second one tested the automatic temporal expectation. Our data shows that both Feature-based Attention and Temporal Attention improve the process of perception. Temporal expectation effects just occur in situations of competitive environment. Hypothesis verification was not conclusive, because of methodological problems
