In this study, we evaluated observers' ability to compare naturally shaped three-dimensional (3-D) objects, using their senses of vision and touch. In one experiment, the observers haptically manipulated 1 object and then indicated which of 12 visible objects possessed the same shape. In the second experiment, pairs of objects were presented, and the(More)
Adults with Down syndrome (DS) develop Alzheimer's disease (AD) neuropathology by 40 years of age. Synaptophysin (SYN) consistently declines with age and is further reduced with sporadic AD. Thus, we hypothesized that SYN would be reduced in DS with AD. The gene for synaptojanin-1 (SYNJ1), involved in synaptic vesicle recycling, is on chromosome 21. We(More)
To better understand individual differences in sensation seeking and its components, including boredom susceptibility and experience seeking, we examined brain responses of high and low sensation seekers during repeated visual experience. Individuals scoring in the top and bottom quartiles from a college-aged population on the Brief Sensation-Seeking Scale(More)
OF THESIS INVESTIGATING AGE-RELATED INHIBITORY DEFICITS IN SPATIAL WORKING MEMORY Age-related inhibitory effects were investigated during spatial memory performance. In Experiment 1, 15 young (M = 20 years) and 16 old adults (M = 70 years) completed two spatial tasks (i.e., Block Suppression Test, Corsi Block Tapping Test) that differed in need for(More)
Despite growing interest in self-care, few studies have explicitly examined the self-care practices of healthcare social workers. This exploratory study investigated self-care among practitioners (N = 138) in one southeastern state. Overall, data suggest that healthcare social workers only moderately engaged in self-care. Additionally, analyses revealed(More)
