The Effect Of Parent Interactions On Young Infants’ Visual Attention In An Object Manipulation Task., Nonah Marie Olesen Aug 2021

The Effect Of Parent Interactions On Young Infants’ Visual Attention In An Object Manipulation Task., Nonah Marie Olesen

Electronic Theses and Dissertations

The Sticky Mittens (SM) task, an object-manipulation task that facilitates typically developing pre-reaching infants’ learning through active experience with objects, is often utilized to understand how experience affects young infants’ learning about objects. SM experience has been shown to increase infants’ attention to objects, object engagement, and object exploration (Libertus & Needham, 2010; Needham, Barrett, & Peterman, 2002) and facilitates development of causal perception (Rakison & Krogh, 2012; Holt, 2016). Although the majority of SM studies have involved parents interacting naturally with their infants, few have focused on how those interactions affect infants’ learning and performance during or after SM. …


The Effects Of Monaural And Binaural Cues On Perceived Reverberation By Normal Hearing And Hearing-Impaired Listeners., Gregory Matthew Ellis Aug 2018

The Effects Of Monaural And Binaural Cues On Perceived Reverberation By Normal Hearing And Hearing-Impaired Listeners., Gregory Matthew Ellis

Electronic Theses and Dissertations

This dissertation is a quantitative and qualitative examination of how young normal hearing and young hearing-impaired listeners perceive reverberation. A primary complaint among hearing-impaired listeners is difficulty understanding speech in noisy or reverberant environments. This work was motivated by a desire to better understand reverberation perception and processing so that this knowledge might be used to improve outcomes for hearing-impaired listeners in these environments. This dissertation is written in six chapters. Chapter One is an introduction to the field and a review of the relevant literature. Chapter Two describes a motivating experiment from laboratory work completed before the dissertation. This …


Assessing The Relationship Between Talker Normalization And Spectral Contrast Effects In Speech Perception., Ashley Atri Assgari May 2018

Assessing The Relationship Between Talker Normalization And Spectral Contrast Effects In Speech Perception., Ashley Atri Assgari

Electronic Theses and Dissertations

Speech perception is influenced by context. This influence can help to alleviate issues that arise from the extreme acoustic variability of speech. Two examples of contextual influences are talker normalization and spectral contrast effects (SCEs). Talker normalization occurs when listeners hear different talkers causing speech perception to be slower and less accurate. SCEs occur when spectral characteristics change from context sentences to target vowels and speech perception is biased by that change. It has been demonstrated that SCEs are restrained when contexts are spoken by different talkers (Assgari & Stilp, 2015). However, what about hearing different talkers restrains these effects …


"Triggers": Systematic And Social Cues For Black College Student Racial Self-Consciousness And Rejection Sensitivity, Race-Based., Leanna T. Luney May 2018

"Triggers": Systematic And Social Cues For Black College Student Racial Self-Consciousness And Rejection Sensitivity, Race-Based., Leanna T. Luney

Electronic Theses and Dissertations

Scholars have examined black student well-being in varying ways including through the framing of race-based rejection sensitivity (Downey & Feldman, 1996; Mendoza-Denton, Downey, Purdie, Davis, & Pietrzak, 2002) and racial self-consciousness (Clark & Clark, 1939). Research shows that black students perform worse academically when they display high levels of race-based rejection sensitivity and racial self-conscious levels (Brannon & Taylor, 2015; Clark & Clark, 1939; Koehler & Skvoretz, 2010), and feelings of racial self-consciousness or rejection sensitivity stem from discriminatory and prejudicial experiences. However, research has not fully connected the broader context surrounding black students in college to their high levels …


Mechanisms Responsible For The Development Of Causal Perception In Infancy., Nicholas A. Holt Aug 2016

Mechanisms Responsible For The Development Of Causal Perception In Infancy., Nicholas A. Holt

Electronic Theses and Dissertations

The aim of the current dissertation was to investigate the mechanisms that contribute to the emergence of causal perception in infancy. Previous research suggests that the experience of self-produced causal action may be necessary to promote the development of causal perception (Rakison & Krogh, 2012). The goal of the current study was two-fold: (1) to further explore the roles of self-produced action, haptic, proprioceptive and visual information, and parental interaction on young infants’ understanding of causality. To assess the impact of these factors on infants’ causal learning, 4½-month-olds were randomly assigned to one four conditions. Three of the conditions (Active …
