Does Working Memory Capacity Modulate The Relationship Between Intentional Mind-Wandering And Task Demand?, Stephen Ware

Electronic Theses, Projects, and Dissertations

Mind wandering (MW) is affected by multiple factors. Among those factors, the present study investigated the effects of working memory capacity on task demands on types of mind wandering. It was hypothesized that individuals with high working memory capacity (WMC) would show more intentional mind wandering in a low demanding task, and in this case, task performance would not be impaired. On the other hand, individuals with low working memory capacity would show more unintentional mind wandering in the high demand condition; therefore, task performance would be affected. Task demand was manipulated with verbal n-back tasks and WMC was measured …

Dual Mechanisms Of Cognitive Control: An Eye Tracking Study, Kyle Mobly

Electronic Theses, Projects, and Dissertations

The purpose of the present study was to attempt to provide an ocular signature for the dual mechanisms of cognitive control (proactivity and reactivity) by utilizing an eye tracker to record gaze patterns while participants were administered a modified version of the AX-CPT 40. Additionally, we sought to clarify whether context updating or maintenance was responsible for the higher Total Visit Duration (TVD) on the cue location during the ISI that was found in previous studies by providing both a short (1.5 seconds) and long (3 seconds) ISI length. This allowed us to disentangle context updating from maintenance by removing …

Body Image Role On Non-Suicidal Self-Injury, Maria Ceja, Stephani Aguiar-Vasquez

Electronic Theses, Projects, and Dissertations

This study explores the association between adolescents body image concerns and self-injurious behaviors among students enrolled in kindergarten through 12th grade. The study is exploratory in nature and uses a quantitative design. The study collected archival data from counseling services provided through alocal school district’s counseling program. More specifically, the archival data was retrieved from initial assessments gathered from students participating in the local school district’s counseling program. Additionally, this research is a call for action that seeks to examine and support the further development of programs geared towards students. This study seeks to expand on the research that guides …

The Effects Of Working Memory Capacity And Trait Anxiety On Visual Short-Term Memory Performance, Celene Gonzalez

Electronic Theses, Projects, and Dissertations

Anxiety is of importance within the field of cognition because it is often associated with adverse effects on attention, information processing, learning and memory (Eysenck, 1992, 2007). In existing literature, it has been reported that trait anxiety hinders cognitive performance (i.e., working memory capacity WMC). However, the relationship between trait anxiety and cognitive performance might be moderated by working memory capacity (WMC). For example, Owens (2014) reported that trait anxiety was negatively correlated with cognitive performance in the low WMC group and positively correlated to cognitive performance in the high WMC group. Although, past research on the working memory system …

Neurological Correlates Of The Dunning-Kruger Effect, Alana Lauren Muller

Electronic Theses, Projects, and Dissertations

The Dunning-Kruger Effect is a metacognitive phenomenon in which individuals who perform poorly on a task believe they performed well, whereas individuals who performed very well believe their performance was only average. To date, this effect has only been investigated in the context of performance on mathematical, logical, or lexical tasks, but has yet to be explored for its generalizability in episodic memory task performance. We used a novel method to elicit the Dunning-Kruger Effect via a memory test of item and source recognition confidence. Participants studied 4 lists of words and were asked to make a simple decision about …

Radio Dispatch Cognitive Abilities And Working Memory, David A. Buitron

Electronic Theses, Projects, and Dissertations

Public safety radio dispatchers incontrovertibly have to manage multiple tasks at any given time, from relaying lifesaving information to field units, to simultaneously overseeing several monitors and keeping up with the radio transmissions in a timely manner. Interestingly, however, the underlying cognitive abilities necessitated for performing such tasks have not been thoroughly investigated. To begin understanding the cognitive faculties that underlie dispatching tasks, we gauged cognitive ability measures relevant to dispatcher duties and introduced Working Memory Capacity (WMC) as underlying the differentiation on performance. The four general dispatcher cognitive factors identified by Peace Officer Standards and Training (POST) literature, were …

Toward A Two-Stage Model Of Free Categorization, Gregory J. Smith

Electronic Theses, Projects, and Dissertations

This research examines how comparison of objects underlies free categorization, an essential component of human cognition. Previous results using our binomial labeling task have shown that classification probabilities are affected in a graded manner as a function of similarity, i.e., the number of features shared by two objects. In a similarity rating task, people also rated objects sharing more features as more similar. However, the effect of matching features was approximately linear in the similarity task, but superadditive (exponential) in the labeling task. We hypothesize that this difference is due to the fact that people must select specific objects to …

Incarceration And Reintegration: How It Impacts Mental Health, April M. Marier, Alex Alfredo Reyes

Electronic Theses, Projects, and Dissertations

ABSTRACT

Background: Previous criminal justice policies have been non-effective leading to overpopulated prisons and unsuccessful reintegration. There is a lack of effective supportive and/or rehabilitative services resulting in high rates of recidivism and mental health implications. Objective: This study investigated the perceived impact that incarceration and reintegration with little to no supportive and/or rehabilitative services has on the mental health status of an individual. The emphasis was on participant perception and not on professional reports because of underreporting and lack of attention to mental health in the criminal justice system. Methods: Focus groups in the Inland Empire and Coachella Valley …
