title: The Turner syndrome: cognitive deficits, affective discrimination, and behavior problems.
abstract: Individuals with sex chromosomal anomalies are known to be at increased risk for learning problems and in some cases social or behavioral problems. Girls with an absent or structurally abnormal second sex chromosome (the Turner syndrome) have been found to have cognitive problem solving deficits and immature, inadequate social relationships. The present study attempted to link cognitive and social problems by assessing the girls' ability to process affective cues. 17 girls with karyotypes consistent with a diagnosis of Turner syndrome were compared to a group of 16 short-stature girls of comparable age, verbal intelligence scores, height, and family socioeconomic status on the Affective Discrimination Task, which required interpretation of affective intention from facial expression. The results revealed that the Turner syndrome girls were less accurate at inferring facial affect than the short-stature controls. Analyses revealed that the Turner syndrome girls performed more poorly on spatial, attentional, and short-term memory cognitive tasks and had more psychosocial problems than the short-stature controls. Ability to discriminate facial affect may be another area of cognitive weakness for girls with the Turner syndrome and may underlie the psychosocial problems found in this sample.
