Cognitive Differences In Parkinson’S Disease With Amyloid Positivity And Negativity, Kenya Luna
Cognitive Differences In Parkinson’S Disease With Amyloid Positivity And Negativity, Kenya Luna
Electronic Theses, Projects, and Dissertations
In Parkinson’s Disease (PD), research has shifted to investigate how biomarkers commonly seen in Alzheimer’s Disease (AD), such as amyloid beta (AB), may be associated with cognitive functioning in PD. AB is considered a reliable biomarker for AD pathology, however in PD there is a lacking biomarker that can accurately reflect severity of cognitive impairment. AD research has shown an association between low AB and cognitive decline, but the data in PD has mixed results. Most studies that analyze cognitive decline and biomarkers do not use a cutoff level and the few that do have a threshold vary greatly in …
The Effects Of Working Memory Capacity And Trait Anxiety On Visual Short-Term Memory Performance, Celene Gonzalez
The Effects Of Working Memory Capacity And Trait Anxiety On Visual Short-Term Memory Performance, Celene Gonzalez
Electronic Theses, Projects, and Dissertations
Anxiety is of importance within the field of cognition because it is often associated with adverse effects on attention, information processing, learning and memory (Eysenck, 1992, 2007). In existing literature, it has been reported that trait anxiety hinders cognitive performance (i.e., working memory capacity WMC). However, the relationship between trait anxiety and cognitive performance might be moderated by working memory capacity (WMC). For example, Owens (2014) reported that trait anxiety was negatively correlated with cognitive performance in the low WMC group and positively correlated to cognitive performance in the high WMC group. Although, past research on the working memory system …
Effects Of Bilingualism On Goal Representation And Maintenance, Amina Saadaoui
Effects Of Bilingualism On Goal Representation And Maintenance, Amina Saadaoui
Theses Digitization Project
The main focus of this study was to examine whether the bilingual advantage in cognitive control is due to the bilinguals' ability to represent and maintain goal information in working memory. Cognitive control, also referred to as executive control, is the ability to inhibit one cognitive task while executing another task.
