"Object Based Attention in Visual Word Processing"
… on whether words are treated like visual objects by the human attentional system. Previous research has shown an attentional phenomenon that is associated specifically with objects: this is known as “object based attention” (e.g. Egly, Driver & Rafal, 1994). This is where drawing a …

Perceptual organization and its influence upon attention
… process lies in the construction of objects. By breaking down our sensory input into objects the mind provides a basis upon which it can begin to scaffold our understanding of the world. This thesis therefore explores the basic stages at which the visual system organizes our sensory …

Saccadic decision-making in dynamic real-world scenes
… to analyze how specific aspects of visual attention shape this decision-making process under natural conditions. This thesis investigates what visual attention operates on in complex scenes, how its underlying perceptual units are formed, and what guides visual exploration behavior, …

The benefits of getting horizontal
… vision is to better understand the mechanisms of attention. This is often accomplished by using models of attention to predict how the placement of stimuli on a computer screen will affect task difficulty. However, recent research has shown there are asymmetries in visual sensitivity across …

Flexibility in object-based selection
A well established finding in the field of visual attention is that attention tends to operate in an object-based manner (i.e., all features of attended objects, including task-irrelevant ones, tend to be co-selected, e.g., O’Craven et al.). However, recent evidence suggests that object-based …

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 …
