Cognitive Intra-Individual Variability: The Effects Of Affect In A Healthy Young Adult Sample, Tovah M.D. Cowan
Cognitive Intra-Individual Variability: The Effects Of Affect In A Healthy Young Adult Sample, Tovah M.D. Cowan
LSU Master's Theses
Cognition is foundational to our experience of the world, but also to how psychologists understand dysfunctions. Cognitive impairment is a feature of a variety of mental disorders, but traditional assessment measures have key limitations in prediction and classification. A proposed alternative is cognitive intraindividual variability (cIIV), which is suggested to measure cognitive control or neural inefficiencies, fluctuating within a task, or over short periods of time. cIIV has been shown to be more sensitive in classification for a variety of conditions than overall performance, including in affective disorders. Further, some research suggests that cIIV is related to self-report cognitive abilities, …
Inattentional Blindness And Auditory Attention: Effects Of Cognitive Load On Visual Awareness, Dillon James Cornett
Inattentional Blindness And Auditory Attention: Effects Of Cognitive Load On Visual Awareness, Dillon James Cornett
LSU Master's Theses
The current study investigated the effects of cognitive load, in the presence or absence of distractors, during a dynamic inattentional blindness (IB) task on IB rate. IB is a phenomenon where one fails to notice an unexpected object (UEO) or event (UEE) that is in full view while attention is occupied. In the present study, the presence of distractors was manipulated (present/absent) to investigate the effects of selective attention in inattentional blindness when inhibition of distractors is required or not required. Undergraduates at Louisiana State University completed a visual task while listening to music embedded with sine wave tones (low …
Apolipoprotein Status And Cognitive Functioning In Adulthood: Role Of Physical Health And Social Network Characteristics, Jennifer Lee Silva
Apolipoprotein Status And Cognitive Functioning In Adulthood: Role Of Physical Health And Social Network Characteristics, Jennifer Lee Silva
LSU Doctoral Dissertations
This study examined the relationships among cognitive function, physical health, social network characteristics, and apolipoprotein (APOE) genotype in participants from the Louisiana Healthy Aging Study. Prior literature has shown that the ε4 allele of APOE is associated with cognitive deficits (Wisdom, Callahan, & Hawkins, 2009). This study failed to find any relation between APOE genotype (ε4 carrier vs. non-carrier) and cognitive ability after controlling for age and education level. Tests for physical health mediation and social network moderation did not alter the ε4/cognition null results. This finding conflicts with prior research suggesting that physical activity and health modify the association …
