This dissertation explores human coordination in rhythmic, verbal, and spatial activity, and how coordination in one of these modes may subsequently impact behavior in another mode. My research examines what effects non-conversational actions have on the alignment of spatial perspectives during conversation. I hope to clarify how data about non-linguistic...
The availability and importance of data is accelerating, and our visual system is a critical tool for understanding it. The research field of data visualization seeks design guidelines – often inspired by perceptual psychology – for more efficient visual data analysis. Data visualization can borrow phenomena, tasks, and methods of...
This dissertation examined gender differences in youth externalizing comorbidity via three studies. Study 1 was a meta-analytic review that provided the first robust estimate of gender differences in youth externalizing comorbidity. Studies 2 and 3 unpacked these gender differences at two levels of analysis: personality (Study 2 and 3) and...
Humans possess the ability to infer and track mental states, which allows for successful interaction in the social world. The collection of processes and representations that makes this possible is referred to as a theory-of-mind (ToM). A large body of work has examined how these abilities develop from infancy to...
Our visual system organizes lines, shapes, and colors into groups, objects, and scenes. This dissertation explores how these higher-level organizations arise, focusing on the contribution of feature-based attention, our ability to selectively enhance a color, shape, or orientation across our visual field. I will present evidence that feature-based attention enables...
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...
Reinforcement sensitivity theory (RST) has enormous potential to become a paradigmatic model of individual differences. However, while its foundations in experimental genetic and neurophysiological research on nonhuman animals are among the strongest in personality psychology, it has perhaps not gained the foothold within the field that it deserves. It is...
Prejudice based on a person’s low socioeconomic status (SES) has been largely understudied in social psychology. In my dissertation research, I argue that understanding a perceiver’s mental model of SES is crucial to explaining anti-poor prejudice. I borrow from work in anthropology to characterize two main mental models of SES—ascribed...
Background: Major Depressive Disorder (MDD) is a significant public health issue. Previous research on the pathophysiology of depression in adults has demonstrated abnormal neural processing associated with depression symptomatology including alterations in reward and aversion circuits. Loss aversion (LA), or the concept that individuals evaluate outcomes based on losses and...
