Cognitive Decline And Contact Sports: The Relationship Between P3 Amplitude And Sub-Concussive Head Impact, Elizabeth Kerman May 2023

Cognitive Decline And Contact Sports: The Relationship Between P3 Amplitude And Sub-Concussive Head Impact, Elizabeth Kerman

Undergraduate Honors Theses

The present study sought to explore the effect of repetitive sub-concussive head impacts on the P3 event-related potential (ERP) amplitude and measures of movement kinematics. University students participating in collision, contact, and non-contact sports at the club and varsity level completed a cued visuomotor adaptation task. Results indicated that participants who estimated experiencing four or more sub-concussive head impacts per week display a significantly reduced P3 amplitude across both normal and adaptive trials. Additionally, participants who estimated experiencing less than four sub-concussive head impacts per week displayed no significant changes in P300 amplitude between “switch” and “stay” trials. This research …


Examining Measures Of Eeg As Biomarkers For Autism Spectrum Disorder, Shuhan Liang May 2023

Examining Measures Of Eeg As Biomarkers For Autism Spectrum Disorder, Shuhan Liang

Undergraduate Honors Theses

A central aim of this study was to determine whether there are consistent differences in a variety of ERPs and/or resting state measures of EEG between children diagnosed with ASD and psychiatric controls. Additionally, we aimed to determine whether any of those differences would generalize to the neural correlates of continuous measures of autistic tendencies in the general population. We classified EEG data into three categories: basic sensory responses, cognitive/perceptual ERPs, and resting state measures. Our study indicated that basic sensory responses and cognitive/perceptual event-related potentials (ERPs) did not differentiate autistic individuals from controls. For resting-state measures, the high gamma …


Aggression In And Out Of The Surrounding Space, Marissa Incer May 2023

Aggression In And Out Of The Surrounding Space, Marissa Incer

Undergraduate Honors Theses

Social isolation is a type of punishment used to address misbehavior in individuals, such as children with time-outs and prisoners in solitary confinement. It was thought to be an effective method for teaching good behavior or alleviating tense situations. However, this type of punishment may worsen the punished individual’s aggression depending on the environment of isolation. The current study was divided into two experiments. In the first experiment, participants were isolated in a small (2x2 feet) or large (6x6 feet) space to observe if the space alone affected their aggression. In the second experiment, a frustration-inducing task was given to …


Investigating The Relationship Between N2pc And Rapid Saccadic Eye Movements, Kezhen Qi Apr 2023

Investigating The Relationship Between N2pc And Rapid Saccadic Eye Movements, Kezhen Qi

Undergraduate Honors Theses

In this study, we investigated the impact of temporal variability on the N2pc component during overt and covert visual search tasks, with a focus on potential differences in the efficiency of search strategies. Employing an eye tracker and a modified algorithm for saccade detection, our analysis considered the potential influence of eye tracker performance and data cleaning methods on the interpretation of results. Additionally, we adopted ERPimage analysis to enhance the rigor of our statistical examination. Our findings confirmed the temporal relationship between the N2pc and first saccade onset, with the N2pc occurring after the saccade. Furthermore, we identified a …
