Young children can sometimes acquire new vocabulary words—even property terms—through indirect learning (e.g. Carey & Bartlett, 1978). We explore two factors that contribute to this ability—perceptual alignment and linguistic contrast. We propose that spontaneous comparison processes lead children to notice key commonalities and differences that facilitate indirect property word learning....
Rhythmic fluctuations of electrical activity in the brain provide insights into the proposed mechanism by which we encode experiences and then maintain, forget, modify, and retrieve them. Yet there is still much to learn about how neural oscillations relate to memory function. The purpose of this research is to discover...
An important tenet in memory research is the dissociation between explicit and implicit memory systems in the brain. Whereas a robust literature exists on the consolidation of memories in the explicit domain, research on implicit memory consolidation is relatively understudied, particularly questions about what is being consolidated and the mechanisms...
Selective attention enables people to focus on a small number of objects, features, or events with good resolution. Sometimes attention may also be less selective and distributed across numerous items, which allows more information to be processed at a lower resolution. The degree to which attention is more or less...
This dissertation aims to address a gap in the literature regarding the effect of the achievement-focused student identity on prosocial values and behaviors, specifically among students who predominantly value prosociality. Largely, research on identity and motivation addresses academic outcomes and psychological well-being outcomes (Settles, Sellers, & Damas, 2002; Jaret &...
A failure to effectively regulate emotions elicited by a stressful life event contributes to symptoms of psychopathology. This regulatory failure may result from a deficit in executive control. For some individuals, executive control is impaired following stress exposure. Thus, for some individuals, when executive control is needed to regulate emotions...
Traditionally, research on perception and sensory systems has considered the senses as independent and modular functions that only converge after sufficient processing in unisensory areas. Recently, however, that view has been called into question with a number of demonstrations of multisensory interactions that may occur as early as primary cortex....
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...
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...
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....
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 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...
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...
"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...
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....
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,...
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...
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,...
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...
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...
