The Use Of Hemifield Eye-Patching For Modifying The Perceptual-Attentional Bias In Healthy Individuals, Randall L. Miller
The Use Of Hemifield Eye-Patching For Modifying The Perceptual-Attentional Bias In Healthy Individuals, Randall L. Miller
Seton Hall University Dissertations and Theses (ETDs)
Healthy individuals do not perceive the left and right sides of space equally, showing a leftward spatial bias on visuospatial tasks. This bias may be more attributed to a perceptual-attentional (PA) component than a motor-intentional (MI) component. While monocular eye patching alters this spatial bias via modification of PA but not MI, hemifield eye patches that occluded the left or right half of the visual field have been shown to be more effective at modifying spatial bias, but only in patients with spatial neglect. Furthermore, it is unclear whether hemifield patching affects PA, MI, or both. The goal of the …
Prism Adaptation Effects On The Attentional Window, Michelle C. Rosenthal
Prism Adaptation Effects On The Attentional Window, Michelle C. Rosenthal
Seton Hall University Dissertations and Theses (ETDs)
Prism adaptation, a visuomotor adaptation procedure that employs a lateral shift of the visual field, has been widely shown to affect lateral biases in the distribution of spatial attention in healthy individuals. The effects of prism adaptation on the size of the attentional window, the limited area of the visual field we attend to and extract information from without moving our eyes, are not fully elucidated. In this study, I investigated the effects of prism adaptation on the size of the attentional window in healthy young adults. This was accomplished via a useful field of view task, which measures the …
Selective Effects Of Selective Attention, Katherine Camille Moen
Selective Effects Of Selective Attention, Katherine Camille Moen
Seton Hall University Dissertations and Theses (ETDs)
Selective Attention is the process by which an individual attends to one stimulus while ignoring other distracting stimuli. Selective attention at encoding has been found to consistently impair memory performance. However, little research has found conclusive evidence as to the impact of selective attention during initial retrieval, and how that impacts retrieval on later tests, or the influence of the types of stimuli that participants are ignoring. The following series of experiments outline how selective attention impairs memory immediately and after a delay, during encoding and retrieval. Experiments 1-3 manipulated attention during retrieval. Experiment 1 found that selective attention during …
