The hypothesis that irritability and contingency detection are negatively correlated was examined in thirty-one 6-month-old infants. Observation and maternal report-based assessments of irritability were correlated with both a criterion score and a continuous score of contingency detection. Results indicated that greater irritability in infants was associated with lower contingency detection scores. Discussion focuses on identifying processes by which the 2 constructs may be associated.
