About Our Research
At the most fundamental level, the purpose of our research is to expand the scientific knowledge and understanding of Attention-Deficit/Hyperactivity Disorder (ADHD) in children. More specifically, our research efforts are focused on examining core deficits of the disorder, namely cognitive impairments in working memory. Ongoing projects in the lab currently involve using experimental methods to isolate components of working memory and examining their functional relationship to facets of the disorder (e.g. hyperactivity, academic achievement).

Prospective Students
Students with interests in working in association with the CLC-IV as graduate students are encouraged to contact Dr. Mark Rapport or his graduate students for questions or additional information. We look for students who are motivated to learn, who possess potential to excel in quantitative science and who desire to become researchers in field of clinical child psychology. Individuals who have been mentored by Dr. Rapport have gone on to hold academic positions at a host of top universities, as well becoming respected experts in their area. A sample listing of past CLC alumni is contained in the People section. For additional information about the University of Central Florida's clinical psychology program, application deadlines, etc., visit the psychology department's website at www.psych.ucf.edu.

Undergraduate Research Assistants
The CLC-IV accepts undergraduate students seeking to benefit from research experience who intended on applying to graduate school. Research assistant's (RA's) will obtain a broad array of skills and experiences from volunteering. Specifically, RA's can expect to gain experience involving the principles of behavioral observation while using the sophisticated Noldus electronic video observation system, advanced statistics, and chiid psychopathology, among others. We are proud to state that past RA's from the CLC have a remarkable 100% acceptance rate in gaining entry into a number of graduate programs, including several Ph.D. programs in clinical and school psychology. For a listing of past RA's and where they have gone, see the People webpage. At minimum, RA's are required to contribute 10 hours of assistance weekly for one year. Thus, sophomores and juniors are especially encouraged to apply. Other requirements for RA positions exist, and individuals expressing interest in applying should contact Dr. Mark Rapport.
