Research in cognitive and developmental psychology typically focuses on urban middle-class, European American populations. Although there has been a recent surge in psychological research that focuses on cultural variation (Cohen & Kitayam, 2007), little is known about the practices that support this variation. Knowledge about these practices is critical for...
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...
Most cognitive research on conceptual structure has studied undergraduate populations and either natural (biological) or artificial (experiment-specific) categories. This project investigates how people with extensive, rich knowledge about a complex real-world domain organize and use that knowledge. The research extends prior work on differences among types of experts within biological...
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...
Although anxiety and depression are clearly distinct from a phenomenological perspective, discriminating these constructs empirically has often been difficult (Clark & Watson, 1991). Both the tripartite model of psychopathology (Clark & Watson, 1991) and the cognitive content-specificity hypothesis (Beck, 1976; Beck & Clark, 1988) were forwarded in an effort to...
On average, homosexual people are more gender nonconforming than heterosexual people. They also show increased distress, possibly due to their stigmatized minority status. Not surprisingly, gender nonconformity and psychological distress may be related, particularly in homosexual men (e.g., Skidmore, Linsenmeier, & Bailey, 2006), although the mechanisms explaining this relationship have...
In the same way that a sculptor shapes a block of stone to reveal the ideal form within, one's relationship partner can help one to become more like one's ideal self (Drigotas, Rusbult, Wieselquist, & Whitton, 1999). This interpersonal process is called "the Michelangelo phenomenon." The current research examines whether...
A striking aspect of human cognition is our capacity for acquiring and using complex knowledge structures, from learning the rules of algebra, to understanding the causal workings of a combustion engine or the structure and processes of the U.S. Congress. These structured representations underlie our ability to generate new inferences,...
Child maltreatment and violence are two major public health concerns in the United States. The relationship between maltreatment and subsequent violent behavior, also referred to as the "cycle of violence", is not well understood. The present study examines whether a history of maltreatment predicts violent behavior in a sample of...
