Abstract
Interacting with visual objects often leads to important events or outcomes that can be positive or negative and probable or improbable. Learning mechanisms in the brain enable us to associate both the value and the likelihood of such motivationally salient outcomes with the sensory events that precede them, so that, in future, we can better predict potential outcomes. In my presentation I will show how value learning can imbue visual stimuli or features with associations related to predictiveness and value and how each type of association may separately influence selective attention and visual working memory processes. Such studies show that mechanisms supporting motivation exert important influences on visual cognition.
