This dissertation study is being conducted by Sandra Wieland, PhD Candidate at the University of Arizona, College of Nursing. This study will be recruiting both identical and fraternal female twin pairs between the ages of 25 and 64. The purpose of this research study is to examine the genetic influences on executive function and self-regulation of body weight.
Participation in this study includes 4 online questionnaires followed by an over-the-phone test of executive function. The online questionnaires are brief, and ask about your goals, your personality, and how your mood has been recently. You and your twin can help make an important contribution to understanding how our ability to plan, remember, and take control can influence our body weight.
What Is Executive Function?
Executive function is a set of mental processes that helps connect past experience with present action. People use it to perform activities such as planning, organizing, strategizing, paying attention to and remembering details, and managing time and space. If you have trouble with executive function, these things are more difficult to do.
