Does Anodal Tdcs Over The Left Prefrontal Cortex Using The F3-Rso Montage Improve Cognitive Control?, Sydney Darling May 2021

Does Anodal Tdcs Over The Left Prefrontal Cortex Using The F3-Rso Montage Improve Cognitive Control?, Sydney Darling

Honors Scholar Theses

Cognitive control is the ability to focus on relevant stimuli while disregarding irrelevant stimuli and is thought to be supported by the prefrontal cortex (see Miller & Cohen, 2001). Transcranial Direct Current Stimulation (tDCS) is a noninvasive brain stimulation technique that modulates the activity of underlying cortex regions through an electric current provided by two or more electrodes on the scalp. This study looks to determine whether anodal tDCS over the left prefrontal cortex can be used to increase cognitive control in healthy participants. Using an F3-RSO montage in a mixed between and within subjects design (with sham vs. anodal …


Design, Programming, And User-Experience, Kaila G. Manca May 2015

Design, Programming, And User-Experience, Kaila G. Manca

Honors Scholar Theses

This thesis is a culmination of my individualized major in Human-Computer Interaction. As such, it showcases my knowledge of design, computer engineering, user-experience research, and puts into practice my background in psychology, com- munications, and neuroscience.

I provided full-service design and development for a web application to be used by the Digital Media and Design Department and their students.This process involved several iterations of user-experience research, testing, concepting, branding and strategy, ideation, and design. It lead to two products.

The first product is full-scale development and optimization of the web appli- cation.The web application adheres to best practices. It was …


Electrophysiological Changes In P200 Latency And Amplitude Of Jittered Orientation Visual Integration Task In Healthy Participants: A Multi-Block Design Eeg Study, Monika M. Rozynski, Chi-Ming Chen Apr 2015

Electrophysiological Changes In P200 Latency And Amplitude Of Jittered Orientation Visual Integration Task In Healthy Participants: A Multi-Block Design Eeg Study, Monika M. Rozynski, Chi-Ming Chen

Honors Scholar Theses

Visual integration, the ability to fuse environmental information such as light, color, shades, and motion to form a representation of a whole cohesive higher-order visual image, is impaired in persons with schizophrenia. Little is known how the P200 component, an event-related potential (ERP) in the parieto-occipital region, is affected in persons with schizophrenia while they perform visual integration tasks, when compared to healthy persons. This study administered Gabor contours that varied in high and low degrees of orientational jitter through the Jitter Orientation Visual Integration (JOVI) task to investigate visual integration by analyzing latency and amplitude of the P200 component. …


Electrophysiological Changes Of N100 Latency And Amplitude In Healthy Participants Performing The Jitter Orientated Visual Integration Task: A Multi-Block Design Study, Fariya Naz Apr 2015

Electrophysiological Changes Of N100 Latency And Amplitude In Healthy Participants Performing The Jitter Orientated Visual Integration Task: A Multi-Block Design Study, Fariya Naz

The present study investigated the differences in processing during visual integration in healthy adults. The visual N100 indexes early visual discrimination and in this case, was hypothesized to show differences in both latency and amplitude depending on the level of difficulty which corresponds to orientational jitter in a visual integration task. Four blocks with pseudo-random levels of jitter were presented to participants in the Jitter Oriented Visual Integration (JOVI) task. Results looking at the Oz channel showed significant reduction in amplitude in the visual N100 during the more difficult levels condition of the task. The multi-block design, originally expected to …
