Transdiagnostic Multimodal Neural Correlates Of Psychosis Dimensions, Dov Bernard Lerman-Sinkoff
Transdiagnostic Multimodal Neural Correlates Of Psychosis Dimensions, Dov Bernard Lerman-Sinkoff
McKelvey School of Engineering Theses & Dissertations
Psychosis refers to a debilitating set of symptoms that impacts individuals, their communities, and society at large. Current psychiatric nosology treats psychosis as a categorical construct. However, recent evidence suggests that a dimensional approach that cuts across extant nosological boundaries may more accurately represent the underlying phenomena contributing to dysfunction in psychosis. One putative domain of transdiagnostic variation is cognitive control, a construct that refers to the set of functions that enable and support goal-directed behavior and regulation of one’s thoughts and actions. Previous analyses in both healthy individuals and individuals with psychosis have led to a number of findings …
Executive Abilities And Academic Achievement In Children With Sickle Cell Disease, Erika Wesonga
Executive Abilities And Academic Achievement In Children With Sickle Cell Disease, Erika Wesonga
Arts & Sciences Electronic Theses and Dissertations
Academic achievement is crucial to a child’s psychosocial and occupational success (Davaoudzadeh et al., 2015; Margari et al., 2013). In children with sickle cell disease (SCD), a genetic disorder resulting in abnormal hemoglobin and significant neurologic sequelae, poor academic achievement is common (e.g. Wang et al., 2001). Studies of typically-developing children have revealed links between academic achievement and neuropsychological abilities, particularly higher-order executive abilities that are mediated primarily by frontal brain regions (Altemeier et al., 2006; Bull & Scerri, 2001). In children with SCD, there is a wealth of evidence that executive abilities are impaired (Berkelhammer et al., 2007), but …
The Effect Of Retrieval Practice On Vocabulary Learning For Children Who Are Deaf Or Hard Of Hearing, Casey Krauss Reimer
The Effect Of Retrieval Practice On Vocabulary Learning For Children Who Are Deaf Or Hard Of Hearing, Casey Krauss Reimer
Arts & Sciences Electronic Theses and Dissertations
The goal of the current study was to determine if students who are deaf or hard of hearing (d/hh) would learn more new vocabulary words through the use of retrieval practice than repeated exposure (repeated study). No studies to date have used this cognitive strategy—retrieval practice—with children who are d/hh. Previous studies have shown that children with hearing loss struggle with learning vocabulary words. This deficit can negatively affect language development, reading outcomes, and overall academic success. Few studies have investigated specific interventions to address the poor vocabulary development for children with hearing loss. The current study investigated retrieval practice …
Prospective Memory Impairment In Parkinson Disease Without Dementia: Cognitive Mechanisms And Intervention, Erin R. Foster
Prospective Memory Impairment In Parkinson Disease Without Dementia: Cognitive Mechanisms And Intervention, Erin R. Foster
Arts & Sciences Electronic Theses and Dissertations
Cognitive impairment among non-demented individuals with Parkinson disease (PD) produces significant disability, reduced quality of life, and restricted participation. This dissertation will cover PD-related impairment in prospective memory, or the ability to remember to execute delayed intentions at the appropriate moment in the future. Prospective memory impairment in PD is increasingly recognized as a functionally and clinically relevant problem and viable target for cognitive intervention. To lay the groundwork for the development of effective interventions for prospective memory in PD, this dissertation examines the cognitive mechanisms underlying prospective memory impairment in PD and the potential of training in a targeted …
