Kuhnert Lab
Director: Dr. Karl W. Kuhnert
Our lab's research centers on leadership and organizational development. Employing a variety of theoretical perspectives and research methods, we have examined personality, gender, and many other variables in conjunction with leadership. One stream of research our lab is engaged in uses constructive/developmental theory to show how leaders make sense of themselves and others. This research has revealed discernible patterns in how people make sense of their world and also how these patterns affect the way that people lead others. In general, we seek to demonstrate how leaders' individual characteristics and development can impact their performance as well as the organization within which they work.

Thomas Lab
Director: Dr. Kecia M. Thomas
Our lab works both in collaboration and as independent initiators of research projects in diversity scholarship, under the direction of Dr. Kecia M. Thomas. Given the rapid change in our nation's demography, we realize that diversity is no longer an option but an organizational reality. As diversity researchers, our lab has the unique opportunity to study a wide range of important workplace issues. We also work in conjunction with the Center for Research and Engagement in Diversity in an effort to collaborate with and learn from diversity scholars across our campus. Currently, we are examining the potential preference for Native African citizens over African American citizens when applying for acceptance and funding at a fictitious undergraduate university. Other projects examine the impact of sexual orientation/identity, racial identity, religious beliefs, and inter-racial relationships on important workplace outcomes (e.g., performance appraisals, likelihood to hire, willingness to partner/mentor, etc.). Through the RED foundation, our lab is actively involved with measuring and improving the climate for inclusion and diversity in applied organizational settings. We have had great success with the Terry College of Business here at UGA, Cincinnati Children's Hospital in Ohio, and we are looking forward to beginning/continuing a number of new projects that include the Department of Agriculture as well as UGA's Franklin College of Arts. As we continue our focus on diversity and inclusion, we hope to continue scholarship in an effort to promote equity, inclusion, social justice and excellence within our workplaces and communities.

Human Cognitive Processing Laboratory
Director: Dr. Richard L. Marsh
The Human Cognitive Processing Lab (HCPL) is collaborating with the Memory, Attention, and Individual Differences Lab (MAID) to investigate the role of individual differences in prospective memory. This research is examining both time-based and event-based prospective memory paradigms to determine if there is a single construct or cognitive process that is common to all prospective memory. Another goal of this research is to study whether individual differences in working memory capacity (and related measures) share similar processes with prospective memory. For example, does a latent prospective memory factor correlate with a latent working memory or general intelligence factor?
The HCPL has also started collaborating with researchers in the Cognitive and Clinical Neuroscience Laboratory to examine the neural correlates of time-based prospective memory.
When people attempt to generate new ideas, they use their past experience. Usually, this information aids in new idea generation but it also has the tendency to result in unconscious plagiarism of friends’ ideas and those of significant others. Our most recent work examines how the generation of new ideas is influenced by the group dynamics and the dyadic interaction between people which may influence the degree to which they come to believe older ideas are actually their own new ideas.
This work was recently discussed in the Boston Globe, read more.

Cognitive and Clinical Neuroscience Laboratory
Directors: Dr. Jennifer McDowell and Dr. Brett Clementz
There are a number of interesting, collaborative projects being conducted in the Clinical and Cognitive Neuroscience Laboratory co-directed by Drs. Brett Clementz and Jennifer McDowell. First is a study using electroencephalography (EEG) to compare brain responses across young, middle-aged, and older adults to determine the effects of aging on how sound is processed in the brain. Second is the evaluation of EEG data collected from twins in collaboration with the University of Minnesota Twin Family Study. By evaluating the similarities and differences in the electrical brain response in identical and fraternal twins, we can help determine the extent to which genetics determines brain activity. Third is a recently completed study using EEG and some specially developed visual stimuli to monitor the allocation of feature-based attention. Fourth, we are in the beginning stages of an exciting study that will optimize our ability to understand where in the brain, and in when in the time course of activity, specific events occur by integrating data from multiple neuroimaging methods: EEG, magnetoencephalography (MEG), and functional magnetic resonance imaging (fMRI). This multi-modal project is designed to test some specific questions about the role of prefrontal cortex in supporting an inhibitory eye movement task that is of interest to researchers as a potential endophenotype for schizophrenia. Finally, we are part of a collaborative team studying the effects of an exercise intervention program on the cognitive processes of overweight children. The aspect of the study conducted in our laboratory is the evaluation of how brain activity is changed (as assessed by fMRI) across time in the group of children who have received exercise training compared to a control group.

UGA Infant Research Laboratory
Director: Dr. Janet E. Frick
The UGA Infant Research Lab (IRL) conducts studies on the development of visual attention and learning in young infants. Currently, the IRL is investigating how well babies, children, and adults can understand visual "cues", like arrows. We know that babies have their attention "cued" to look in particular ways by stimuli such as arrows or eyes. We are trying to better understand how this ability develops.
The IRL also is examining the development of face perception. This work involves investigating how infants identify faces and process facial expressions. Comparisons will be made among 6-month-olds, 9-month-olds, and adults.
A study is currently being wrapped up on the relationship between nutrition and visual development in young babies. We are interested in how certain nutritional factors in the mother's diet and in formula or breast milk may impact the baby’s ability to see very dimly lit stimuli. To study this, we are measuring "contrast sensitivity" in 4-6 month old babies. This work has been discussed in the Athens Banner-Herald.

Additionally, IRL has recently begun examining individual differences in how young children develop dual representation (i.e., understanding that a symbol object represents two aspects of that object) using scale models.

The Family Relationships in Late Life Laboratory (FRILL)
Director: Dr. Gail M. Williamson
The Family Relationships in Late Life (FRILL) project, in collaboration with the UGA Neuropsychology and Memory Assessment Laboratory, examines a wide range of issues, including physical and mental health, cognitive function, interpersonal relationships, and quality of care.

Currently, the FRILL lab is analyzing longitudinal data to assess whether caregiver attachment and caregiver-care recipient pre-illness relationship predict changes in caregiver mental health and quality of care provided. Findings will: (a) provide a working profile of caregivers at risk for psychological distress imposed by the caregiving role, and (b) identify care recipients at risk for poor quality of care. Additional longitudinal analyses are being conducted with the primary goals of: (a) identifying predictors of change in caregiver depression, and (b) investigating how changes in caregiver mental health status relate to changes in the quality of care provided to the care recipient. The lab is also completing a project investigating two particular factors that consistently have been shown to be related to caregiving outcomes: (a) quality of the pre-illness interpersonal relationship between caregiver and care recipient, and (b) caregiver perceptions of social support availability. Findings from these studies will assist clinicians and public health care professionals in targeting caregiving outcomes to improve the well-being of both caregivers and their care recipients.

A fourth project, on quality of elder care, is also near completion. Quality of informal elder care typically has been conceptualized as a unidimensional construct, ranging from poor (e.g., neglectful and/or abusive) to adequate. Data from the first FRILL project, however, suggests that quality of informal care may, in fact, be multidimensional (Dooley, Shaffer, Lance, & Williamson, 2007 – PDF attached). In this line of research, we provide evidence for the existence of three dimensions of quality of care: (a) potentially harmful behavior, (b) adequate care, and (c) exemplary care.

McDowell Laboratory
Directors: Dr. Jennifer McDowell
In 2006, the Coverdell Center for Biomedical and Health Sciences opened new doors for brain imaging research at the University of Georgia. This research-dedicated, state-of-the-art facility is a "laboratory without walls", architecturally designed to eliminate departmental boundaries and to encourage community learning. The facility is the home of BIRC, UGA’s Bio-Imaging Research Center, and is the proud host of a new 3-Tesla MRI system. Jennifer McDowell, a professor in the psychology and neuroscience departments, is involved in several studies using functional MRI. Her most recent research includes an investigation of the relationship between eye movement performance in undergraduate students and schizophrenia-related symptoms* and a study investigating how practice affects the neural substrates supporting eye movement performance in schizophrenia**. Dr. McDowell also collaborates with the Georgia Prevention institute in Augusta, Georgia. Their research on the effect of exercise on cognition in overweight children*** was nationally recognized last year in an article by USA today (http://www.usatoday.com/news/health/2007-10-29-exercise-brains_N.htm).

Bernstein Laboratory
Director: Dr. Irwin Bernstein

Yerkes Field Station – Wilson Lab
Desiree Sharpe, a graduate student in Dr. Bernstein’s laboratory, is currently working on a couple of projects with Dr. Mark Wilson at Yerkes National Primate Research Center of Emory University. The research in the Wilson lab predicts that in subordinate female rhesus monkeys, reproductive deficits are due to an attenuation of gonadotropin secretion by an upregulation of CRH, a consequential phenomenon following natural exposure to chronic psychosocial stress. The model used in this project also focuses on the impact of polymorphisms in the gene that encodes the serotonin reuptake transporter (SERT), as short promoter length variant in the SERT gene is associated with increased vulnerability to stressors in humans and rhesus macaques.
Zoo Atlanta & Gorilla Haven
Tori Vratanina and Desiree Sharpe initiated a project working with gorillas at both Zoo Atlanta and Gorilla Haven. The primary contact person at Zoo Atlanta is Dr. Tara Stoinski. Gorilla Haven was founded by Jane and Steuart Dewar and is a natural habitat sanctuary located in Morganton, GA. This research has a cognitive focus, addressing whether gorillas are able to correctly maximize a food reward when given a choice of two symbolic quantities represented by tokens of varying value.

Crystal Laboratory
Director: Dr. Jonathan Crystal
In the Crystal lab we are actively exploring several facets of animal cognition, specifically the ways in which internal mechanisms shape the learning of behavioral repertoires. Animals have been shown to possess an intrinsic episodic-like memory sense called "What-Where-When" memory. Using an eight arm radial maze, we are investigating the temporal mechanisms of what-where-when memory.
We are also evaluating whether or not a rodent is able to assess their own knowledge. This ability, called metacognition, has historically been a dividing line that separates human cognitive abilities from other animals. Presently we are evaluating a metacognition paradigm in rodents that has been designed to test for metacognitve control processes. Here is a link to a recent article in Newsweek that showcases some of this research, http://www.newsweek.com/id/35401
The lab is also actively investigating the role of temporal perception using operant condition. Currently we are investigating the role Dopamine plays in memory retrieval when the subjects possess memories for two distinctive intervals of time that are cued by the same stimulus.
We are also exploring ideas for an interdepartmental collaboration with the Human Cognitive Processing Laboratory. We will be investigating the differences and similarities in prospective memory in human and rodent subjects.

Holmes Laboratory
Director: Dr. Phillip Holmes
Researchers in the laboratory of Dr. Phil Holmes are interested in understanding how the brain protects itself from damage caused by excess physiological activity, and how exercise enhances this protective mechanism. It is the excess activity, or neural hyperexcitability, that is responsible for much of the brain damage caused by epilepsy, stress, trauma, stroke, and neurodegenerative diseases.
The laboratory of Dr. Holmes, in collaboration with the laboratory of Dr. Rod Dishman in Kinesiology, seeks to understand the role of the neuropeptide galanin and its receptors in the mitigation of excitotoxic damage, and how voluntary wheel running may enhance this effect. Techniques include in situ hybridization histochemistry and receptor autoradiography, observation of in vivo glutamate activity by means of a voltammetric system, intracranial electroencephalographic measurements, seizure analysis, as well as histological techniques.

Primate Cognition and Behavior Laboratory
Director: Dorothy M. Fragaszy
Brian Stone is working on a project involving capuchin monkeys' and chimpanzees' ability to point to objects using a laser pointer. This project investigates these species' use of pointing in goal-directed behavior. To compare capuchins and chimpanzees in this study, Brian collaborates with researchers at the Language Research Center of Georgia State University.
 
Jessi Crast is investigating social learning in capuchin monkeys, specifically in the areas of visual attention and social facilitation. A collaboration with researchers at the Language Research Center of Georgia State University is underway to look at social influence on skill acquisition of a foraging task in social groups of capuchins.
Freya Liu studies the nut-cracking behavior in wild capuchin monkeys in Boa Vista, Piaui, Brazil. Her recent work explores how the monkeys explore properties of the tools. Another project focuses on the development of nut-cracking in young monkeys.
Erin Colbert-White is studying quantity discrimination in capuchin monkeys in collaboration with researchers at the National Research Council in Rome, Italy. She is looking at discrete quantity judgment between 1, 3, and 5 and the extent to which they're able to sum pairs of quantities. In addition, in collaboration with researchers at the University of California at Riverside and the University of Georgia's Institute of Artificial Intelligence, Erin is working on the use of language by an African Grey parrot to regulate and maintain a social relationship with her care-taker, Betty Jean Craige, using both facultative and social features of language. A recent press article discussed Erin's research: http://onlineathens.com/stories/101208/liv_342183948.shtml
