A Comparison Of Attentional Reserve Capacity Across Three Sensory Modalities, John Brill
A Comparison Of Attentional Reserve Capacity Across Three Sensory Modalities, John Brill
Electronic Theses and Dissertations
There are two theoretical approaches to the nature of attentional resources. One proposes a single, flexible pool of cognitive resources; the other poses there are multiple resources. This study was designed to systematically examine whether there is evidence for multiple resource theory using a counting task consisting of visual, auditory, and tactile signals using two experiments. The goal of the first experiment was the validation of a multi-modal secondary loading task. Thirty-two participants performed nine variations of a multi-modal counting task incorporating three modalities and three demand levels. Performance and subjective ratings of workload were measured for each of the …
The Relative Sensitivity Of An Olfactory Identification Deficit In Individuals With Schizotypal Personality Features, Vidyulata Kamath
The Relative Sensitivity Of An Olfactory Identification Deficit In Individuals With Schizotypal Personality Features, Vidyulata Kamath
Electronic Theses and Dissertations
Olfactory identification deficits have received recent attention as a potentially useful endophenotype for schizophrenia. Examination of this deficit in individuals with schizotypal personality features (SPF) offers an alternative approach to multiple confounds present when examining individuals with schizophrenia. The aim of the current study was to compare the relative sensitivity of performance on measures of olfaction identification and sustained attention to the presence of SPF. Twenty-six undergraduates were defined as having SPF based on scoring in the top 10% of the Abbreviated Schizotypal Personality Questionnaire (SPQ-B; mean age 19.6, SD = 1.1; 62% female). These individuals were compared to twenty-six …
