Reduced Effects Of Social Feedback On Learning In Turner Syndrome

Turner Syndrome is a genetic condition caused by a complete or partial loss of one of the X chromosomes. This sex chromosome aneuploidy has a reported incidence of 1:1700-1:2000 female births and a wide-spread of manifestations. This study examined the impact of social and non-social feedback on learning in women with Turner Syndrome and a sex- and age-matched control group. Results indicated that social feedback led to a more explorative choice behavior in the control group, resulting in reduced learning compared to non-social feedback. No effects of social feedback on learning were found in Turner Syndrome, suggesting that women with Turner Syndrome may be less sensitive to social influences on reinforcement learning than the general population.
