Age-Related Changes In Visual Spatial Performance, Samantha Farrell
Age-Related Changes In Visual Spatial Performance, Samantha Farrell
Seton Hall University Dissertations and Theses (ETDs)
Visual spatial skills allow individuals to understand the relationship between objects, people, and the environment for their everyday activities. Visual spatial abilities incorporate visual, motor, and cognitive components, each of which changes across the lifespan. The current study examined the effects of age-related changes and practice type on visual spatial performance. Participants between 40 and 79 years of age were asked to complete the Block Design Task (BDT) by using nine blocks to recreate various designs. Both accuracy and latency were measured to examine these changes. Task difficulty and practice type were varied and cognitive abilities were measured via MMSE …
Spatial Learning Deficit In The Hiv-1 Transgenic Rat: Discerning Place From Strategy Learning, Abigail Lashomb
Spatial Learning Deficit In The Hiv-1 Transgenic Rat: Discerning Place From Strategy Learning, Abigail Lashomb
Seton Hall University Dissertations and Theses (ETDs)
HIV -1 infection is associated with a constellation of cognitive and motor deficits collectively termed HIV associated dementia. With the onset of HAART treatment, these cognitive effects have become more mild, but also more prevalent. The lack of a proper animal model to study these cognitive effects of HIV has lead to the development of a new transgenic rat. This rat expresses the HIV -1 genome with functional tat and gp 120 viral proteins. These proteins are linked with direct neural toxicity as well as the induction of cytokines and other indirect means of neuronal damage. As part of the …
