The relationship between Executive Functions and Peer Rejection was explored. Thirty-Five students in an urban elementary school, (mean 10.7 years of age (sd=2.8), 34% male, and 88% African American) completed measures of executive functions: KABC-II Rover, The Wisconsin Card Sort and NEPSY-II Statue (below age 9) or The Iowa Gambling Task (age 9 and up). Classmates reported who was not a preferred play mate: a measure of rejection. Executive Functions were not significantly related to Rejection across the sample, but among the children with the lowest Executive Functions, The Wisconsin Card Sort was significantly negatively related to Rejection (-0.61, p = 0.04) suggesting poor Cognitive Flexibility may be a risk factor for Rejection. Performance on the Iowa Gambling Task was found to be positively correlated with Rejection (0.4, p = 0.008) suggesting that high impulse control may also be a risk factor for rejection among adolescents. This was consistent with a finding of a positive correlation between Office Discipline Referrals and popularity (0.4, p = 0.008) among the sample. Implications for practice are also discussed including the difficulty of managing behavior when bad behavior is related to popularity.
