A significant amount of research has investigated the underlying neural mechanisms that enable the direction of attention throughout a search array. The biased competition model (Desimone & Duncan, 1995) proposes that an attentional template (the neural instantiation of the search target) is created when the target representation in visual working memory (VWM) is communicated to frontal regions which then bias early visual areas to attend to target features. Despite this, much of the current work focuses solely on the target representation in VWM, which is only one small part of the attentional template according to biased competition. Thus, I used …

Neural Dynamics Of Categorical Representations Used For Visual Search, Ashley Phelps
Electronic Theses and Dissertations, 2020-2023
Decades of visual attention research have predominantly used pictorial search paradigms that cue participants with the exact perceptual details of the target. However, in everyday life, people often search for categories rather than specific items (i.e., any pen rather than a specific pen). To study visual attention in a more realistic context, researchers can use categorical search paradigms that cue participants with text indicating the target category. In these instances, one must rely on long-term memory to retrieve categorical features of the target. Both experiments in this study were a reanalysis of experiments previously designed and collected by Schmidt and …
