Numerous studies of forest fragmentation have found a negative relationship between density of Peromyscus leucopus and forest fragment size. This relationship may be caused by both more food, and more cover from predation in smaller fragments, which have more structurally complex understory vegetation than larger fragments. However, we do not know the extent to which the proximity of understory vegetation affects selection of nesting sites within fragments. We hypothesized that nest boxes in highly vegetated areas would be utilized more often by P. leucopus than nest boxes in sparsely vegetated areas.
High-stake decisions are based on neuropsychological test data, such as diagnosis of specific learning disabilities and mental retardation. Thus, it is crucial to understand how anxiety and stress affect test scores on the most popular and current IQ measure, Wechsler Adult Intelligence Scale – Fourth Edition (WAIS-IV). Previous studies have shown negative effects of self-reported anxiety on performance on various cognitive tasks; however, these studies either used a single measure of anxiety or tested a limited number of subtests from previous versions of the WAIS. The current study sought to examine the relationship of anxiety (as determined by self-report data), stress (as determined by physiological data), and performance on the WAIS-IV.
