Assessment of Attention Network Function in Multiple Sclerosis
(2021-07-12)Cognitive deficits are highly prevalent in multiple sclerosis (MS). Impaired cognitive functions, such as attention abilities, can be among the most limiting changes in individuals rated as having low neurologic disability. ... -
THE COGNITIVE CONSEQUENCES OF FORGETTING: AN INVESTIGATION OF IOR IN ITEM-METHOD DIRECTED FORGETTING
(2015-04-20)This dissertation investigated the occurrence of an increased magnitude of inhibition of return (IOR) after Forget (F) compared to Remember (R) memory instructions using a directed forgetting cueing paradigm. In such a ... -
Developing and validating a combined attention systems test
(2018-08-31)Modern research on the phenomena of attention has motivated an increasingly nuanced view of its subsystems and their relations. However, popular tools for the measurement thereof are limited in their design in ways that ... -
The effects of dual n-back training on the components of working memory and fluid intelligence: An individual differences approach
(2013-08-23)Measures of working memory capacity are associated with performance on a variety of cognitive tasks. A number of recent studies have provided evidence that training working memory can lead to improvements in fluid intelligence ... -
EXPLORING THE ROLE OF ATTENTIONAL WITHDRAWAL IN ITEM-METHOD DIRECTED FORGETTING THROUGH VISUAL SEARCH
(2023-04-04)We embedded a serial and pop-out visual search into the study phase of an item-method directed forgetting paradigm to assess attentional availability following instructions to remember (R) or forget (F). Study words were ... -
INHIBITIONS OF RETURN: TWO INHIBITORY ORIENTING BIASES
(2021-08-17)Inhibition of return (IOR) is an inhibitory aftereffect of visuospatial orienting, typically resulting in slower responses to targets presented in an area that has been recently attended. This thesis begins by briefly ... -
Investigating Performance Under Two Forms of Temporal Cueing
(2020-08-18)Temporal attention is the focusing of cognitive resources to an interval in time to prepare a response and improve perception. Recently, it has been shown that there are two independent forms of temporal attention: one ... -
Investigating The Influence Of Attentiveness On Motor Imagery Performance
(2023-11-15)Although much research has focused on motor imagery, the mental rehearsal of movement, little has examined the influence cognitive deficits have on its performance. Recent findings have shown that motor imagery is ... -
IT’S ABOUT TIME: CONVERGING METHODS FOR DISTINGUISHING THE INFLUENCE OF ENDOGENOUS AND EXOGENOUS MODES WITHIN THE TEMPORAL DOMAIN OF ATTENTION
(2024-08-28)Endogenous (volitional) and exogenous (reflexive) modes of temporal attention are independent and differently impact performance (Lawrence and Klein, 2013; McCormick, Redden, Lawrence, & Klein, 2018). Despite this, these ... -
Mechanisms of inhibition of return: Brain, behavior, and computational modeling
(2013-04-12)Inhibition of return (IOR) is a cognitive phenomenon whereby reaction times (RTs) are slower to cued relative to uncued targets at cue-target onset asynchronies (CTOAs) greater than approximately 300 ms. One important ... -
A Neurophysiological Study of the Impact of Mind Wandering During Online Lectures
(2019-08-15)Lecture-format Massive Open Online Courses (MOOCs) were once thought to have the potential to permanently change higher education, though they did not live up to their original hype. Among the many posited reasons for this ... -
The Parallel Encoding of Actions Within a Sequential Grasping Task: Strategic, Motor, or Perceptual Interference Effects
(2022-11-18)Every day we are constantly performing consecutive grasping actions to complete our desired goals. Although we have a good scientific understanding about how the brain programs one grasping action towards a single object, ... -
Perceptual and Motor IOR: Components or Flavours?
(2011-05-02)The most common evidence for inhibition of return (IOR) is the robust finding of increased response times to targets that appear at previously cued locations following a cue-target interval exceeding ~ 300 ms. In a ... -
The Role of Attention in Walking in Parkinson's Disease
(2019-08-29)Parkinson’s disease affects both cognitive and motor function. The purpose of this study was to look at the role of attention and walking in people with Parkinson’s disease (n = 15) as compared to a healthy, matched control ... -
There is a Missing-Phoneme Effect in Aural Prose Comprehension
(SAGE, 2016-05-06)When participants search for a target letter while reading, they make more omissions if the target letter is embedded in frequent function words than in less frequent content words. This phenomenon, called the missing-letter ... -
What a Simple Letter-Detection Task Can Tell Us About Cognitive Processes in Reading
(Psychological Science, 2016)Understanding reading is a central issue for psychology, with major societal implications. Over the past five decades, a simple letter-detection task has been used as a window on the psycholinguistic processes involved ...
