Neural Correlates Of Individuation And Subordinate-Level Categorization Of Other-Race Faces In Infancy, Kelly Roth
Neural Correlates Of Individuation And Subordinate-Level Categorization Of Other-Race Faces In Infancy, Kelly Roth
Doctoral Dissertations
Perceptual narrowing is a domain-general process in which infants move from a broad sensitivity to a wide range of stimuli to developing expertise within often experienced native stimuli (Maurer & Werker, 2014). One outcome of this is the own-race bias, characterized by an increasing difficulty in discriminating other-race faces with age and experience for those raised in a racially homogenous environment (Anzures, Quinn, Pascalis, Slater, Tanaka, & Lee, 2013). Recent theorists have proposed that this is due to a categorization-individuation process, wherein infants begin to categorize non-native stimuli, such as other-species’ faces, but individuate native stimuli, such as often-experienced human …
The Effects Of Aging On Attention In Associative Learning, Katie Wheeler
The Effects Of Aging On Attention In Associative Learning, Katie Wheeler
Masters Theses & Specialist Projects
In this study we investigated how aging affects attention to predictive and uncertain cues during associative learning. According to Mackintosh’s theory of predictiveness (1975), attention will be allocated to cues that most reliably predict an outcome. An opposing theory of uncertainty from Pearce and Hall (1980) suggest attention will be allocated to cues whose outcomes are uncertain. Although these theories are contradictory, both are well supported in the associative learning literature. There is evidence that young and older adults give more attention to cues that are predictive compared to nonpredictive cues (Mutter et al., 2019), and that young adults respond …
Differentiating Cognitive Deficits Between Adhd And In Utero Polysubstance Exposure, Dylan J. Seitz
Differentiating Cognitive Deficits Between Adhd And In Utero Polysubstance Exposure, Dylan J. Seitz
Doctor of Psychology (PsyD)
ADHD is the most prevalent psychiatric disorder in children, affecting their executive and overall well-being as a result (Barkley, 2014; Shaw, Gogtay, & Rapoport, 2010). A rampant increase in new diagnoses of ADHD suggests the potential for misdiagnosis. Stimulants are the first line of treatment and associated with a number of deleterious long-term consequences for those misdiagnosed (Urban & Gao, 2014a). This is of particular concern for children prenatally exposed to substances as in utero use acts on similar neural mechanisms impacted by ADHD – leaving the children vulnerable to misdiagnosis and contraindicated intervention (Derauf, Kekatpure, Neyzi, Lester, & Kosofsky, …
The Effects Of Pointing Gestures On Visual Attention, Samaria J. Hamilton
The Effects Of Pointing Gestures On Visual Attention, Samaria J. Hamilton
Honors College Theses
Visual attention is a process that involves concentrating on select features, such as sensory cues, within the complex environment. Sensory cues within the visual field capture and redirect our attention. Previous research on eye gaze revealed that direct gaze captures attention. In the present study, pointing gestures and motion cues were tested together in a visual search task to examine their effects on attention. Participants were instructed to identify a target letter presented on one of four hands. Initially, two hands displayed a pointing gesture while the other two displayed an open gesture. Next, a target letter appeared, one open …
