Behavioral activation (BA) trains depressed clients to engage in more positive activities in order to increase their experience of pleasure and accomplishment, thereby reducing depression. Recent research suggested that BA might be as effective in treating depression as current leading treatments, such as cognitive-behavioral therapy (CBT) and antidepressant medication (Jacobson,...
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....
"Anosognosia" or lack of insight into one's own illness is not uncommon in central nervous system disease. Neurodegenerative diseases of the brain that cause dementia are often associated with anosognosia. A lot is known about anosognosia in Alzheimer's disease but relatively little is known about lack of insight into illness...
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...
The current research tested the principles of role congruity theory of prejudice, which states that prejudice arises from an incongruity between a group stereotype and social role characteristics (i.e., the attributes and behaviors prescribed by the social role), such that prejudice occurs when members of a group enter or attempt...
The aim of the present investigation was to examine the nature of individuals' parasocial relationships (one-sided attachments to media figures, Horton & Wohl, 1956). Five studies were designed to assess the prevalence and strength of individuals' attachments to their favorite television characters, manipulate exposure to the character or control targets,...
The representation and communication of spatial information is important to the functioning of children and adults in the physical world. Yet little research has included both areas in the same studies. This research program was designed to investigate both the communication and representation of spatial information within a developmental context....
Recent work exploring children's verb learning in the laboratory has generated some interesting contradictions. Some studies have found that children as old as 4 years old are unable to reliably map a novel verb to an action (e.g., Kersten & Smith, 2002; Imai, Haryu, & Okada, 2005), even though much...
Across all levels of education, persistent academic achievement gaps exist between students from higher and lower socioeconomic status (SES) backgrounds. Despite these daunting odds, many students from lower-SES backgrounds manage to maintain high levels of academic motivation and persist in the face of difficulty. One factor that has been shown...
This dissertation presents a program of research on cultural cognition of the natural world, involving long-term research with indigenous Ngöbe partner communities (Panama) and selected comparisons to Western samples (US). In two series of experiments focused on agency concepts, we show that cultural frameworks recruit distinct principles for inferring agency...
