Changes In Hemodynamic Response To Faces, Scenes, And Objects In A Visual Statistical Learning Task: An Fmri Analysis, Aaron T. Halvorsen

Honors Theses

Learning causes changes in brain activity and neural connections. Statistical learning is an implicit learning process that involves extracting regularities from the environment and finding patterns in stimuli based on their transitional probabilities. The following study describes an attempt to elucidate temporal changes in hemodynamic activity for three category-specific brain areas using functional magnetic resonance imaging (fMRI). Blood oxygen-level dependent signal (BOLD) responses were collected while subjects viewed faces, scenes, and objects with high and low transitional probabilities in an fMRI scanner. We expected brain activity to show a temporal shift in timing of activation when comparing BOLD signal responses …

Increasing The Frequency Of Tutors' Reinforcement Of Compliance Behaviors, Sruthi Rameshkumar

Honors Theses

Abstract

Compliance behaviors occurring prior to the delivery of an instruction, such as handing over preferred items, making eye contact, and folding hands in the ready position help prepare students for success in discrete-trial training (DTT) interventions. These behaviors are usually taught in early intervention with a continuous reinforcement schedule, but once they are mastered, they are rarely revisited or maintained. Without intermittent reinforcement of these behaviors, they are likely to decrease in frequency and may lead to the use of restrictive or intrusive methods to gain compliance during DTT sessions. The current study used a multiple-baseline across participants design …

Effects Of Diagnostic Labels On College Students' Perceptions Of Children With Autism Spectrum Disorder, Sarah Grace Cowell

Honors Theses

The Center for Disease Control reports current research that indicates 1 in every 68 children in the United States has the diagnostic label of Autism Spectrum Disorder. Research literature of the past 20 years has warned of the possible dangers of labels, such as Autism Spectrum Disorder, and the potentially negative impact these labels can have on an individual throughout a lifetime.

This project investigates college students' perceptions of the label Autism Spectrum Disorder in regard to a child's educational potential and later employment. College students viewed a four-minute video of a child in solitary play. One-half of the participants …
