Megan S. Dunlap
O-si-yo! Hello! I am a fifth year student in the Clinical Psychology program at Oklahoma State University. In 1997, I received my B.S. in special education at Northeastern State University in Tahlequah, Oklahoma. After working one year in a psychology research lab at the University of Oklahoma, I started graduate school at OSU.

As a member of Dr. Maureen Sullivan's Child Behavior Lab, I am involved in research examining various aspects of parent and child interactions and effective parental techniques. My master's thesis was a controlled laboratory study for which we utilized a detailed coding system to analyze mother and child interactions.

While at OSU, I have also been involved in research and clinical work at the Center on Child Abuse and Neglect (CCAN) in Oklahoma City. I have participated in a cognitive-behavioral group therapy program for children with sexual behavior problems and their caregivers, and am still working on several research projects examining components of that program.

Currently, my practicum positions include working at CCAN on a project examining effectiveness of an Indian Health Service training program for professionals serving adolescent sex offenders and also working with a psychologist from the Cherokee Nation at the Claremore Indian Hospital.

If you are interested in learning more about the psychology program at OSU or would like additional information about Dr. Sullivan's research lab, please feel free to email me your questions at dunlapmegan@hotmail.com.

Raegan B. Smith
I am a fifth year student who entered graduate school at OSU after completing a B.A. in Psychology at the University of Oklahoma in Norman. I am a recent addition to Dr. Sullivan's lab, as I completed my master's thesis under the supervison of Dr. Frank Collins. Since then, my research interests have shifted to child and parent-related issues. I am particularly interested in Parent-Child Interaction Therapy (PCIT), and I have spent a great deal of time performing cognitive assessments on children aged 3 months to 7 years in my practicum placement. My dissertation is planned to address questions about the relationship between parenting skills and cognitive competence, which emerged from my experience with PCIT and cognitive assesssment. I continue to work with Dr. Collins on a study in which the aim is to reduce environmental tobacco smoke exposure to infants discharged from the Neonatal Intensive Care Unit at Children's Hospital in Oklahoma City.

Laura A. Knight
I am a fourth year student in the Child Behavior Lab. My research interests include posttraumatic distress in children and the effects of parenting strategies on child behavior. My master's thesis examined children's long-term posttraumatic distress following the tornadoes of May 3, 1999 and the role of coping and attributions in the development and maintenance of posttraumatic distress. My thesis helped develop an ongoing interest attributions, which I will further explore with my dissertation. I plan to examine the effects of manipulating parents' attribution for young children's behavior on parental affect and response to behavior.

I earned my undergraduate degree in theatre from Roger Williams College (now University) in Bristol, Rhode Island. After graduation, I spent several years as an actress/waitress in Chicago before returning to school to earn a Master of Arts in Clinical Psychology from Roosevelt University. When not consumed with my graduate studies, I enjoy visiting with friends and spending quality time with my kittens.


Chuck Edgington
I am a third year graduate student in the Child Clinical Psychology program. I am the husband of an unstoppable woman and the proud father of two beautiful children. We enjoy going to the zoo, spending time at the park, and going for walks.

I graduated with a Bachelor of Science degree in Psychology from the University of Utah in June 1998. As an undergraduate I worked with Dr. Paul Florsheim on the Cross Ethnic Adolescent Parenthood Study. The focus of many of these studies involved the specific aspects of father-child interactions.

Since arriving at OSU I have been working with other graduate students in the lab on toddler studies examining mother-child interactions. My thesis project will examine child compliance to parental requests in response to specific parenting strategies (e.g. reasoning, nuturance). The study will include a sample of both mothers and fathers with their toddler age children, thus allowing for comparisons between mothers and fathers.


Tamara C. Wilburn
I am a second year student in the Clinical Psychology program at Oklahoma State University. I also completed my undergraduate education here at OSU, where I recieved a B.S. in Family Relations and Child Development and a B.A. in Psychology. My research interests include a variety of issues concerning children, such as behavior problems and the effects of trauma.

Outside of school I enjoy spending time with family and friends, reading, and playing with my dog Bailey. If you have any questions regarding OSU or the Psychology Department feel free to email me at wilbutc@okstate.edu.


Caleb W. Lack
I am a second year student in the Clinical Psychology program here at OSU. I graduated with an Honors Degree in Psychology from OSU in May 2001. My undergraduate research examined factors that were related to religious attitudes in college students, but my interests now lie in the area of children's reactions to natural disasters and other traumatic experiences. My master's thesis will be focusing on gathering data to see how seasonal change influences anxiety and distress levels in children in a diaster-prone area.

Outside of psychology, I enjoy spending time with my wife Emily (who is working on her Doctorate of Veterinary Medicine), reading comic books, and studying comparative mythology and religion.
