Working Memory Task Performance In Children With Sli: A Behavioral And Erp Study, Megan V. Mcveety Sep 2021

Working Memory Task Performance In Children With Sli: A Behavioral And Erp Study, Megan V. Mcveety

Dissertations, Theses, and Capstone Projects

In addition to language deficits, children with Specific Language Impairment often show deficits in tests of various aspects of working memory, including capacity, updating, and selective attention. The purpose of the present study is to examine the specific drivers of differences in working memory processing in 8–11 year-old children with and without SLI using behavioral and electrophysiological measures. Participants completed an n-back task with three working memory load conditions (0-back, 1-back, 2-back), with the addition of distractor trials at the 1-back and 2-back levels. The SLI group performed significantly less accurately across all task conditions. The children with SLI also …


The Effect Of A Mindfulness-Based Intervention On Attention And Cognitive Control As A Function Of Smartphone Notifications., Joshua D. Upshaw Jul 2021

The Effect Of A Mindfulness-Based Intervention On Attention And Cognitive Control As A Function Of Smartphone Notifications., Joshua D. Upshaw

Graduate Theses and Dissertations

Barriers to accessing mobile technology, particularly smartphones, have decreased substantially since the iPhone’s release in 2007, resulting in increased ownership and usage across all ages, genders, and races. Despite their ubiquity in our society, relatively little empirical work has investigated the influence of smartphones on our higher order executive functioning. Prior work has linked smartphone use with impaired cognitive control during cognitively demanding tasks, especially in heavier smartphone users. The goals of the current study were twofold. First, the study aimed to examine the effects of smartphone notifications on cognitive control and attention. And second, to determine the effects of …


Mental Fatigue: Examining Cognitive Performance And Driving Behavior In Young Adults, Abigail F. Helm Apr 2021

Mental Fatigue: Examining Cognitive Performance And Driving Behavior In Young Adults, Abigail F. Helm

Doctoral Dissertations

Mental fatigue causes an increase in task-based EEG theta and alpha power and a decrease in performance (for a review, see Tran et al., 2020). However, little is known about the emergence of mental fatigue in resting state EEG recordings and whether the progression of mental fatigue over time is influenced by individual differences. The current dissertation examined the utility of resting state EEG as a measure of mental fatigue by testing whether EEG power changed in young adults over the course of a cognitively demanding battery of tasks. The current dissertation also tested how this measure of mental fatigue …


When The Brain Plays A Game: Neural Responses To Visual Dynamics During Naturalistic Visual Tasks, Jason Ki Jan 2021

When The Brain Plays A Game: Neural Responses To Visual Dynamics During Naturalistic Visual Tasks, Jason Ki

Dissertations and Theses

Many day-to-day tasks involve processing of complex visual information in a continuous stream. While much of our knowledge on visual processing has been established from reductionist approaches in lab-controlled settings, very little is known about the processing of complex dynamic stimuli experienced in everyday scenarios. Traditional investigations employ event-related paradigms that involve presentation of simple stimuli at select locations in visual space and discrete moments in time. In contrast, visual stimuli in real-life are highly dynamic, spatially-heterogeneous, and semantically rich. Moreover, traditional experiments impose unnatural task constraints (e.g., inhibited saccades), thus, it is unclear whether theories developed under the reductionist …
