1. Facial Emotion Recognition and Social Functioning in Children With and Without Attention-Deficit Hyperactivity Disorder Marissa Reynolds The Pennsylvania State University Thesis Advisor: Dr. Cynthia Huang-Pollock 192 participants ages 8-12 completed the Emotion Recognition Task INDEPENDENT VARIABLES:  ADHD or Control status (Hypothesis 1)  Gender (Hypothesis 2)  Age (Hypothesis 2)  Reaction time to and accuracy in identifying happy, sad, scared and angry faces from the Emotion Recognition Task (Hypothesis 3) DEPENDENT VARIABLES:  Reaction time to and accuracy in identifying happy, sad, scared and angry faces from the Emotion Recognition Task (Hypotheses 1 and 2)  Parent Social Skills Rating Scale – PSSRS (Hypothesis 3)  Teacher Peer Relations Scale – TPRS (Hypothesis 3) Testing Hypothesis 1 Testing Hypothesis 3 Introduction ADHD Issues with attention, hyperactivity and impulsivity Affects all areas of functioning and can persist into adulthood Symptom severity varies by age and gender Social Competence Strong predictor of prognosis for children with ADHD Difficulty with social cues & peer relations (ie. victimization) Facial Emotion Recognition More difficulty in identifying emotions, especially sadness & anger Currently unclear if emotion recognition deficits are related to social competence deficits Testing Hypothesis 2 ADHD (n=129)Control (n=63) MeasureM (SD) F POFA RT to happy faces 1542.16 (327.06)1417.14 (277.48)F(1,190) = 6.808, p = 0.010, η p 2 = 0.035 POFA RT to sad faces 1992.32 (501.67)1842.79 (329.91)F(1,190) = 4.304, p = 0.039, η p 2 = 0.022 POFA RT to scared faces 1956.88 (417.89)1853.20 (420.06)F(1,190) = 2.597, p = 0.109, η p 2 = 0.013 POFA RT to angry faces 1972.34 (458.03)1857.92 (448.29)F(1,190) = 2.678, p = 0.103, η p 2 = 0.014 POFA accuracy to happy faces 9.38 (1.01)9.76 (1.653)F(1,190) = 3.916, p = 0.049, η p 2 = 0.020 POFA accuracy to sad faces 6.98 (1.88)7.62 (1.73)F(1,190) = 5.219, p = 0.023, η p 2 = 0.027 POFA accuracy to scared faces 8.02 (1.70)8.37 (2.05)F(1,190) = 1.493, p = 0.223, η p 2 = 0.008 POFA accuracy to angry faces 7.44 (1.94)7.94 (1.46)F(1,190) = 3.207, p = 0.075, η p 2 = 0.017 Controls displayed significantly faster reaction times to and greater accuracy in identifying happy and sad faces. One Way ANOVA of POFA Measures by ADHD Status Note: POFA = Pictures of Facial Affect; RT = Reaction Time There were no significant results of gender. Younger children displayed slower reaction times to happy and sad faces.

Correlations between Participant’s Age and POFA Measures There were no significant results of emotion recognition measures upon ratings of social skills and peer relations.

Hypothesis 1 Significant differences for happy and sad faces, but not for scared and angry faces Previous research indicates that children with ADHD have less success in identifying sadness, fear and anger Future research should seek a consensus as to which particular facial emotions are difficult for children with ADHD to identify Hypothesis 2 Gender did not have a significant influence on facial emotion recognition The effects of age are most likely due to the tendency of younger children to experience more severe ADHD symptoms Future research should seek to determine if this is a common problem among younger children, the potential consequences, and the necessity of interventions Hypothesis 3 No significant correlations were found between measures of emotion recognition and parents’ and teachers’ ratings of social functioning and peer relations Does not replicate results of study by Kats-Gold, Besser, & Priel, 2007 Lack of consistency may be the result of differences in participant demographics Limitations Limited Generalizability – small sample size and lack of diversity Disgust and surprise were not measured Results cannot compare performance of children with ADHD on Emotion Recognition Task while on medication versus off medication Methods Hypotheses 1.There will be a main effect of ADHD status on measures of facial emotion recognition 2.Males and younger participants will have poorer performance on measures of facial emotion recognition than females and older participants 3.Poorer performance on measures of facial emotion recognition will be correlated with greater social functioning and peer relation issues Results ResultsResults Discussion
