Students often change majors during college, and most workers change jobs throughout their careers. Yet the diverse opportunities for entering natural science, technology, engineering, and mathematics (STEM) fields are often overlooked during college and beyond. This dissertation therefore analyzed four large nationally representative datasets to characterize the pathways for joining...
Psychophysiological investigations of human sexuality have revealed more complexity than might be naively assumed. The sexual arousal patterns of heterosexual and homosexual men are relatively straightforward, with both groups showing substantial responses to erotic stimuli of their preferred sex and much smaller responses to their nonpreferred sex. Bisexual men, in...
Efficient and accurate processing of internally- and externally-generated information is enhanced by the presence of multisensory signals that can provide redundant information about percepts or events. However, efficient usage of multisensory signals requires implicit perceptual knowledge of the potential or likely relationships between signals encoded within each sensory modality. If...
Although chronic stress has been shown to be significantly associated with depression, this relationship has not received adequate attention, particularly in adolescent samples. One gap lies in the examination of whether particular domains of chronic interpersonal stress are uniquely related to risk for depression. Furthermore, the degree to which chronic...
The majority of research on voluntary visual attention has focused primarily on specific attentional processes. While we know much about individual attentional abilities such as shifting attention among spatial locations, tracking multiple objects and maintaining attention for specific targets, we know little about how these attentional processes relate to one...
The human brain shows great flexibility to adjust itself to dynamically ever-changing environment. Despite more than 100 years of cognitive brain research, the dynamical aspect of cognitive process has remained poorly understood compared to the static aspect of that. This dissertation concerns the dynamic character and functional significance of periodically...
The present studies aimed at developing a lie detection paradigm immune to countermeasures, while the theoretical issues of top-down influence of task requirement on subliminal semantic priming were investigated. In Experiment 1, subjects were presented supraliminal acquaintance and non-acquaintance names, which were subliminally primed by another acquaintance or non-acquaintance names....
Why would someone's judgments and choices disregard the consequences he or she cares about most? Considerable research appears to show that in many contexts, people show precisely this paradoxical tendency. Researchers interpret these results as showing that people sometimes make choices on the basis of moral factors -- factors that...
