Extensive research has been conducted linking stress to increased allostatic load and degradation of various organs over time. In the brain, the hippocampus appears to be particularly vulnerable. This deterioration is manifest clinically by impaired performance on tasks of declarative memory. The Social Readjustment Ratings Scale (SRRS) is an inventory of high intensity psychosocial stressors. This instrument has previously been used to help calculate risk of disease. Using measurements of stressful life events, it may be possible to similarly predict risk of cognitive impairment. To test this, the current study explored the cumulative effect of discreet psychosocial stressors that have …

Bilateral presentations of brief (250 ms), unmasked emotional and neutral stimuli were examined in two experiments with primarily female samples. Reaction time and accuracy data were used to measure perception of emotion and skin conductance response (SCR) was used to measure experience of emotion. Both words and pictures were used to account for hemispheric differences in language and visuospatial dominance. Response time was faster to emotional pictures than words. Reaction time and speeded accuracy data did not support right hemisphere hypothesis (RHH) or valence hypothesis (VH) in the expected manner. Data suggested emotion caused greater interference under speeded conditions in …
