One's experience of shifting attention from the color to the smell to the act of picking a flower seems like a unitary process applied, at will, to one modality after another. Yet, the unique experience of sight vs smell vs movement might suggest that the neural mechanisms of attention have been selectively optimized to employ each modality to greatest advantage. Relevant experimental data can be difficult to compare across modalities due to design and methodological heterogeneity. Here we outline some of the issues related to this problem and suggest how experimental data can be obtained across modalities using more uniform …
A Psychometric Evaluation Of Computerized Attention Measures In Young Children With Neurofibromatosis Type 1, Sara Katharine Pardej
A Psychometric Evaluation Of Computerized Attention Measures In Young Children With Neurofibromatosis Type 1, Sara Katharine Pardej
Theses and Dissertations
Children with neurofibromatosis type 1 (NF1) often demonstrate difficulties with attention and executive functioning that can be evident even starting at a young age. Despite this consistent finding in the literature, there has been no research to determine which measures of attention are most suitable for use with children with NF1. Recently, there have been several computerized measures of attention and executive abilities that have become available to researchers and clinicians. This study explored the National Institute of Health Toolbox Flanker, Dimensional Change Card Sort, and List Sort Working Memory; Cogstate Identification; and Conners Kiddie Continuous Performance Test, second edition …
Attention Capture By Episodic Long-Term Memories: Evidence From Eye Movement Data, Allison Eleanor Nickel
Attention Capture By Episodic Long-Term Memories: Evidence From Eye Movement Data, Allison Eleanor Nickel
Theses and Dissertations
Successfully navigating the world on a moment-to-moment basis requires the interaction of multiple cognitive processes. Therefore, studies that examine when and how these fundamental processes interact can provide important insights into how we behave. Many studies indicate that long-term memory can facilitate search for a target object (e.g., contextual cueing), however, the ways in which long-term memory might capture attention and disrupt goal-directed behavior have not been well studied. In five experiments, questions about whether encoded objects might capture attention, even when they are task-irrelevant, were addressed. Each experiment began with an encoding phase, where participants were instructed to commit …
Neural Circuitry Underlying The Intrusion Of Task-Irrelevant Threat Into Working Memory In Anxiety, Daniel Stout
Neural Circuitry Underlying The Intrusion Of Task-Irrelevant Threat Into Working Memory In Anxiety, Daniel Stout
Theses and Dissertations
Dispositional anxiety is an important risk factor for the development of anxiety and other psychological disorders. Symptoms commonly expressed by highly anxious individuals include intrusive memories, uncertainty, and worry — all occurring in the absence of immediate threat. This raises the possibility that anxious individuals have difficulty governing threat’s access to working memory, the mental workspace where goal-related information is actively retained for guiding on-going behavior. Using functional magnetic resonance imaging (fMRI) while 81 subjects completed a well-validated working memory task, I show that threat-related and neutral distracters unnecessarily gain access to working memory, as evidenced by increased neural activity …
Facilitating Visual Selective Attention Via Monetary Reward: The Influence Of Feedback, Hedonic Capacity, And Lifetime Major Depressive Disorder, Lauren Elizabeth Taubitz
Facilitating Visual Selective Attention Via Monetary Reward: The Influence Of Feedback, Hedonic Capacity, And Lifetime Major Depressive Disorder, Lauren Elizabeth Taubitz
Theses and Dissertations
Recently, several researchers have demonstrated that reward enhances visual selective attention; however, no one has evaluated how individual differences in reward sensitivity or psychopathology involving disturbances in hedonic capacity (e.g., Major Depressive Disorder (MDD)) affect this process. In this investigation, a novel incentivized visual search task was developed to unite the literatures on reward facilitation of attention with the studies of individual differences in hedonic capacity and remitted MDD (rMDD). 161 undergraduates responded to self-report measures and completed standard and incentivized visual search tasks. In the standard task, subjects had to indicate if a letter F (target) was present or …
Relations Between Fine Motor Skill And Parental Report Of Attention In Young Children With Neurofibromatosis Type 1, Christy Casnar
Relations Between Fine Motor Skill And Parental Report Of Attention In Young Children With Neurofibromatosis Type 1, Christy Casnar
Theses and Dissertations
Neurofibromatosis type 1 (NF1) is one of the most common genetic disorders presenting in approximately 1 in 3,000 live births. NF1 is a highly variable condition with a large number of complications. A common complication is neuropsychological problems, including developmental delays and learning difficulties that affect as many as 60% of patients. Research has suggested the children with NF1 often have poorer fine motor skills and are at greater risk for attention difficulties than the general population. Furthermore, recent research is beginning to demonstrate a relationship between fine motor skills and attention in older children; however, very little research has …
