Global enhancement of task‐irrelevant dimensions of attended objects
Experiments on the neural mechanisms of feature-based attention suggest that features are selected in parallel across the visual field (Treue & Trujillo, 1999). Moreover, feature-based attention spreads not only to the task-relevant feature in an unattended location, but also to a task-irrelevant …

What and where : a Bayesian inference theory of visual attention
… theoretical framework described in this thesis, attention is part of the inference process that solves the visual recognition problem of what is where. The theory proposes a computational role for attention and leads to a model that predicts some of its main properties at the level of …

Reinforcement Learning Describes the Computational and Neural Processes Underlying Flexible Learning of Values and Attentional Selection
Attention and learning are cognitive control processes that are closely related. This thesis investigates this inter-relatedness by using computational models to describe the mechanisms that are shared between these processes. Computational models describe the transformation of stimuli to …

Orientation-specific Control of Attention
… matched to a sought-for color captures attention involuntarily, thus violating either temporal or spatial control of attention. However, whether an irrelevant distractor that matches a sought-for orientation can capture attention is still unknown. A task of rapid serial visual …
