Are there anisotropies in covert and overt visual orienting?
(2010-09-01)Two recent studies suggest that Inhibition of Return (IOR) varies in magnitude as a function of target location for overt orienting tasks but not covert orienting tasks. Unfortunately, methodological differences between ... -
ATTENTION BIASES AND SOCIAL SKILLS IN YOUTH WITH ANXIETY
(2023-07-21)Background: While attentional biases towards negative stimuli have previously been linked to the development and maintenance of anxiety disorders, attentional biases in anxiety remain understudied using dynamic social ... -
DEVISING A MODIFIED FLANKER TASK TO OBTAIN EVENT RELATED BRAIN POTENTIALS FOR THE ASSESSMENT OF ATTENTION
(2014-08-21)Electrophysiological indices of attention provide insight into the neural processes underlying attention. These indices include the P300 and its sub-components, the P3a and P3b, which are event related potentials (ERPs) ... -
Exploring the Dissociations between Overt and Covert Mechanisms of Spatial Attention and Inhibition of Return
(2013-09-06)Prompted by oculomotor theories of attention, the present experiments explore the role of saccade activation in the generation of two cueing effects: exogenous capture (Experiment 1) and inhibition of return (IOR; Experiment ... -
Inhibition of Return for Endogenous Colour Cues
(2017-12-18)Inhibition of Return (IOR) is a phenomenon of attention where responses are slower toward a recently attended location, compared with novel locations. Recently, coloured signals have been used endogenously (MacInnes, Kruger ... -
INHIBITORY CONSEQUENCES OF GRASPING MOVEMENTS: IS GRASPING THE SAME AS REACHING?
(2016-08-22)Studies have shown that past actions can impact present and future actions. More specifically, inhibition of return (IOR) is a phenomenon in which participants respond slower to previously attended areas compared to novel ... -
Insight, Thinking, and the Nature of Self: On the Methods of Philosophy and what "I" Refers to
(2024-08-13)My thesis is on the methods of philosophy and the nature of the self. I look at both Eastern and Western philosophy to show the core methods of philosophy within each branch and how they apply their philosophical methods ... -
IS INTERFERENCE IN GRASPING PRODUCED WHEN COVERT ATTENTION IS DIRECTED TO NON-TARGET OBJECTS?
(2016-12-08)Previous literature has shown that when covert attention is directed to a non-target object while grasping a target fruit, the non-target’s size can influence the peak grip aperture for the target fruit (Castiello, 1996). ... -
On the inhibitory consequences of visuospatial orienting: Inhibition of return?
(2016-02-29)Responding is typically slowest toward (an “output” bias) or about (an “input” bias) targets presented at the location indicated by a spatially uninformative visual transient (a “cue”) when the onset asynchrony between the ... -
Psychometric Properties and Age-Related Effects of the Combined Attention Systems Test
(2023-04-25)Attention is a multifaceted cognitive process that is important for functioning in daily life. The study of attention commonly focuses on three networks: alerting, orienting, and executive control. Despite the rich literature ... -
The Role of Attention and Working Memory in Reading in Young Adults With a History of Reading Difficulties: Mechanisms and Treatment
(2022-08-12)University students with a history of reading difficulties (HRD) have ongoing reading and academic challenges. Understanding the mechanisms underlying these students’ reading difficulties and identifying ways to improve ... -
The Role of Attentional Control in Working Memory: Effects of Cognitive Load, Aging, and Stroke
(2015-01-16)Working memory is a limited capacity system that relies on attentional control mechanisms to filter out task irrelevant information for optimal performance (Broadbent, 1958). The aim of this dissertation was to investigate ...
