I am interested in human motivation.  One area of research concerns our desire to understand and control our surroundings, and how experiences with lack of control affect the way we think and act in subsequent situations.  A second area of interest concerns the difference between intrinsic and extrinsic motivational orientations toward activities.  Generally, how does doing something (e.g., playing a game, interacting with another person) as an end in itself versus doing that same thing as a means to an end affect our performance on that activity and our interest in engaging with the activity in the future?  Other motivational interests include the effects of the emotions and emotional expressions of regret and remorse as they affect the likelihood of future action and procrastination (inaction inertia), and reactions to moral transgressions (punishment desires, and the phenomenon of moral luck).

My current research interests are in two areas.  One is the psychology of anomalous or psi experiences - that is, experiences that are not readily explained within conventional scientific paradigms.  I am particularly fascinated by anomalous experiences that are transpersonal (i.e., one's consciousness seems to be located beyond the person, in another time and/or place); an example would be the past-life experience.  My second area of interest is in the psychology of death and dying - more specifically, how people in professions that deal on a regular basis with animal death (veterinarians, wildlife rehabilitators, animal shelter staff, etc.) cope with the stress of euthanasia in their practices.

My present research efforts are focused on studying children?s perceptions of gender norms. I am currently working on a series of studies evaluating what type of social pressure children experience and how this contributes to their conformity to gender roles. What I?ve found is that children who have perceptions that gender is important to other people (familiar people like parents, siblings, peers) are more likely to show gender-typed behavior, but only in contexts where gender is highlighted as important. Even subtle cues about situational importance of gender influence children. However, depending on what the activity is, boys and girls respond differently to subtle and explicit cues of the importance of gender.

My primary research interests focus on how cultural tendencies and situational cues to attend to self interact to shape the physiological, subjective, and expressive aspects of emotional responding in healthy and clinical populations.  My studies employ a multi-method approach (subjective reports, facial behavior, physiological responding) and focus on comparing emotional responding of European Americans and Asian Americans, groups with different cultural norms regarding expression of emotion. The literature on cultural differences in emotional responding suggests that individuals from Asian cultural contexts experience and show emotions less intensely than individuals from European American cultural contexts. These findings are consistent with accounts that suggest that mainstream American cultural norms encourage the open expression of emotions, and Asian cultural norms encourage the moderation of emotion.  Expanding on this literature, I propose two mechanisms mediating cultural differences in emotional responding: 1) attention to self cues, and 2) impaired capacity to engage with cultural norms (among individuals with Major Depressive Disorder).  In my research, I demonstrate that the pattern of cultural differences in emotional responding can be reversed among individuals attending to relational self cues and among depressed individuals.  These findings suggest that cultural influences on emotional responding are more nuanced than previously thought.

My lab group studies human memory and considers such issues as the mechanisms of veridical and distorted memory, how subjective experience affects memory, and memory disorders (resulting frontal brain damage, aging, and Alzheimer's disease).  An example of veridical and distorted memory research would entail comparing susceptibility to memory errors as a result of imagination or misleading questioning.  Subjective experience refers to such things as confidence in memory and qualitative judgments about memory.  Ongoing research questions include: (1) the interaction between subjective experiences during encoding and retrieval.  How does subjectivity direct encoding processes?  How accurate are we in predicting what we will later recall?  Do predictions at recall correspond to confidence at retrieval?  Can subjectivity be used to distinguish between veridical and false memories?  (2) Accessibility of contextual cues.  How do contextual cues (e.g. external and internal context) affect encoding and retrieval?  When is encoding of context impaired?  When is encoded context unavailable?  (3) Aging and memory. We are exploring age-related changes in memory in all of the above--in identifying mechanisms that underlie accurate and inaccurate recall, in investigating how subjectivity directs encoding and retrieval, and examining the accessibility and utilization of context. We use cognitive/behavioral and psychometric techniques to investigate these questions.  The research questions we address have direct applications to real-world problems, including eyewitness suggestibility, and memory changes as a function of normal and pathological aging.

Following an injury to the brain or spinal cord, there are initiated a number of processes that cause further damage to the injured area.  The general process is called secondary pathology.  My research has focused on a specific aspect of secondary pathology that is mediated by immune cells that are recruited to the injury.  These immune cells produce molecule called quinolinic acid which is toxic to nerve cells.  My previous studies have investigated the time course of the accumulation of this molecule, the benefits on structure and function of blocking this accumulation, and the mechanism of damage to other CNS cells in a guinea pig model of spinal cord injury.  I would like to further this research by investigating the cognitive effects of quinolinic acid accumulation and blockade in a gerbil stroke model.

My research examines preschooler’s social behaviors and friendships.  Most research examining early friendships has focused on the positive aspects of these relationships (e.g., links to prosocial behavior, cognitive development, or improved school-readiness).  However, my research supports the existence of a darker side to early friendships by examining relational aggression.  Relationally aggressive behaviors are those intended to hurt or harm another's interpersonal relationships.  For example, excluding someone from an activity, gossiping about them, or giving them the "silent treatment." The use of these behaviors has been tied to several negative social-psychological adjustment indices in children and adolescents (e.g., peer rejection, reduced prosocial behavior, and depressive symptoms). Relational aggression has most commonly been studied in older children. However, my research demonstrates that preschool children use relational aggression.  Unexpectedly, children who are more relationally aggressive have more friends and choose friends who are similar to themselves in aggression levels.  Some children use relational aggression against their mutual friends, while other children do not.  Surprisingly, using relational aggression against a mutual friend during the preschool years is not associated with negative outcomes (as it is for older children).  My current focus is to gain a better understanding of why this is, including the processes that occur in relationally aggressive children’s friendships and the implications of these relationships for the transition to kindergarten.

My research has focused on perceptual learning for vision, particularly object-oriented depth perception as derived from multiple visual cues and influenced by haptic (touch) information. Using a multi-modal virtual reality environment to provide subjects with conflicting or ambiguous sensory information, I explore how sensory information is combined and the plasticity of visual percepts. A fascinating aspect of work in this field is an increased acceptance of the concept that humans must learn to see just as they must learn to walk and talk, and that visual perceptions are highly context-dependent and task-specific. My research interests also extend to related issues such as decision making with uncertainty, how information is processed and integrated in social situations, and probabilistic models of beliefs.

My research involves the role of cognitive control in long term memory.  Memory is often conceptualized as having opposing controlled and automatic processes.  For example, if you have just moved and someone asks for an address, you may start to give them your old address.  This would be an automatic component of memory.  However, you may catch yourself and then give out the new address.  This is an example of cognitive control overriding automatic processing. My research examines this basic idea in a number of different areas.  “Can you use cognitive control to suppress a memory?” and “Can you use cognitive control to resist misleading or erroneous information?” are two research questions that I have investigated recently.  I also use different populations and techniques to examine this question.  We currently use older adults and people with Alzheimer’s disease to examine how cognitive control changes.  Along with different populations, we also use neuropsychological testing and neuroscientific techniques like MRI to examine how the concept of cognitive control is linked to different biological systems.

My research involves using experimental neuroanatomy to reveal functional pathways in the brains of nonhuman primates and, most recently, magnetic resonance imaging (MRI) to reveal pathways in the human brain.  I have used sensitive pathway tracing techniques to delineate the connectional organization of the forebrain in nonhuman primates and have found connections that were not evident using older techniques.  I have a special interest in how cortical-subcortical pathways serve sensory processing and sensorimotor integration, and in how cortical pathways allow cognition and motor behavior to be influenced by emotion and motivation. I am studying pathways in rhesus monkeys that carry visual information from association areas to other cortical regions.  I have also begun a new line of research using MRI to reveal cortical pathways in the human brain that previously have been shown only in nonhuman primates.  I hope that this latter project will lead to greater understanding of how lesions in the human brain, e.g., from strokes, affect pathways that travel through the damaged brain regions.
