There is a certain condition that exists in modern Japan that plagues people’s lives and causes their world to come to a halt. Here, the mere thought of leaving their room is unthinkable, let alone going to school or working. They fill their time with games and other mindless entertainment,...
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...
Substance abuse is one of the most critical public health problems affecting juvenile detainees. Previous research suggests that a significant proportion of juvenile detainees with substance use disorders do not receive treatment prior to or during detention. Using data from the Northwestern Juvenile Project, a large-scale longitudinal study of juvenile...
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...
Background: More than 81 percent of African-American women are overweight or obese. In addition to being heavier than Whites, African-Americans have a harder time losing weight and are less likely to engage in physical activity. A growing body of literature suggests several barriers to physical activity that prevent African-American women...
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...
Despite its prevalence, cost, and association with high risk for negative outcomes, there is a lack of empirically-based procedures for effective treatment of dual diagnosis in adolescents. The present study attempts to address the need for research informing effective treatment of this population. Strengths have been found to predict positive...
