GIDeCA – Gene by Environment Interactions on Decision Making in Children with different ADHD Symptoms
GIDeCA assesses biological and psychosocial family-related influences on the ability to delay rewards and on risky decision-making behavior in children with different ADHD symptoms.
Children with Attention Deficit Hyperactivity Disorder (ADHD) are known to be exceedingly impulsive. For instance, they prefer receiving a small gift immediately instead of waiting for a bigger gift they will receive later on. In addition, they decide in favor of options that offer a large gain but are unlikely to be reached, rather than voting for options with a high probability for a small gain.
Different gene variants correlate with a reduced ability to delay rewards and with risky decision making. Moreover, there is evidence that psychosocial and family-related aspects have an influence on the ability to delay a reward.
We assume that genetic as well as psychosocial and family-related factors correlate with the ability to delay rewards and risky decision-making. Furthermore, we assume that the effects of family-related risk factors are particularly significant in individuals with a particular genetic disposition.
200 children aged between eight and twelve years will take part in the study. They will be assessed thoroughly by psychologists. Furthermore, saliva samples will be obtained from the children for a molecular-genetic test and the parents and children will work on a task together. The ability to delay rewards and risky decision-making behavior will be assessed by means of playful and partly computer-based tasks the children generally enjoy.
