• Abstract

  Although praised for their rationality, humans often make poor decisions, even in simple situations. In the repeated binary choice experiment, an individual has to choose repeatedly between the same two alternatives, where a reward is assigned to one of them with fixed probability. The optimal strategy is to perseverate with choosing the alternative with the best expected return. Whereas …

• Abstract

  The initial theories on attentional capture mechanisms by an irrelevant stimulus proposes that a stimulus is able to capture attention in a purely automatic fashion, and that the critical factor determining this attentional capture is the stimulus salience. On the other hand, there are crescent evidence on the literature of the last two decades that, at least on some conditions, the physi…

• Abstract

  The nature of the spatial distribution of attention across the visual field is still a hotly debated topic. Mathematical modeling in this field, especially when temporal dynamics are included, is in an early stage. Yet, a more thorough knowledge of the spatiotemporal properties of attention is necessary to advance the understanding of its role in the flash-lag effect (FLE). The FLE is a v…

• Abstract

  The neural mechanisms of decision-making define the transition from sensory input and perceptual construction to those responsible for action selection and execution. In this project, sequences of repeated binary choices will be employed to investigate the role of distinct perceptual dimensions (spatial, chromatic, semantic or affective stimuli) in defining decision-making strategies empl…
