Correspondence Between Haptic And Visual Perception Of Stand-On-Ability: Do Hills Look As Steep As They Feel?, Jonathan Kenealy Doyon
Correspondence Between Haptic And Visual Perception Of Stand-On-Ability: Do Hills Look As Steep As They Feel?, Jonathan Kenealy Doyon
Master's Theses
Vision and haptics play a central role in perceiving environmental layout to guide action. Hajnal, Wagman, Doyon, and Clark (2016) demonstrated that visual perception of stand-on-ability is accurate compared to action capabilities, whereas haptic perception of stand-on-ability reliably underestimates action capabilities. This finding contradicts Gibson’s (1979) theory of equivalence in perceptual systems, which suggests that perception should be equivalent regardless of modality. Previous comparisons of visual and haptic perception tested the modalities in isolation. The current experiment directly compares visual to haptic perception of stand-on-ability by using one perceptual system to estimate the other. Observers viewed a surface set to …
Global/Local Processing In Incidental Perception Of Hierarchical Structure, Mark S. Mills
Global/Local Processing In Incidental Perception Of Hierarchical Structure, Mark S. Mills
Department of Psychology: Dissertations, Theses, and Student Research
The goal of the current thesis is to provide a framework for investigating and understanding visual processing of hierarchical structure (i.e., local parts nested in global wholes, such as trees nested in forests) under incidental processing conditions—that is, where processing of information at global and local levels is both uninformative (cannot aid task performance) and task-irrelevant (need not be processed to perform the task). To do so, a novel method combining two widely-used paradigms (spatial cueing and compound stimulus paradigms) is used for implicitly probing observers’ perceptual representations over the course of processing. This compound arrow cueing paradigm was used …
Parents And Teachers’ Perceptions And Clinical Diagnosis Of Autism Among White And Non-White Groups, Margaret Gopaul
Parents And Teachers’ Perceptions And Clinical Diagnosis Of Autism Among White And Non-White Groups, Margaret Gopaul
School of Psychology Publications
The pervasiveness of autism has significantly increased over the past 2 decades with the 2014 Center for Disease Control and Prevention report indicating 1 in 68 children are diagnosed with Autism Spectrum Disorder (ASD). Early intervention is recommended as the most effective treatment approach. Nevertheless, previous research has indicated that White children are diagnosed with ASD about 1.5 years earlier than are Non-White children. A current gap remains in literature regarding ASD and different racial groups, and evidence has been inconclusive regarding disparities in identifying and diagnosing ASD. To fill this gap, this study investigated the relationship between child race, …

The Effects Of Affective Arousal On Color Perception And Memory, Nicole Elizabeth Lang
The Effects Of Affective Arousal On Color Perception And Memory, Nicole Elizabeth Lang
Senior Projects Spring 2016
The link between affective arousal, color perception, and color memory was explored by inducing fear, sadness, or embarrassment in 158 participants who them completed a color perception and memory task. It was predicted that participants experiencing fear or embarrassment would more often correctly identify and remember red and green than a neutral condition whereas experiencing sadness would lead to less correct identification and memory for blue and yellow than neutral. There was only a marginally significant effect of fear on color memory for red. In the low arousal condition, there was an effect of fear on color memory for green …
