The relationship between temperament style and understanding of human goal-directed action in infants

Abstract

The purpose of this research was to investigate the relationship between temperament style and understanding of goal-directed action in 10–11-month-old infants. Infant social understanding was assessed using a looking-time measure similar to Woodward (1998). This method yielded two measures of infant social understanding; ‘decrement of attention’ (a measure of infant attention during habituation) and ‘novelty preference’ (an index of infants’ understanding of goal-directed behavior). Temperament style was provided by online parent report (IBQ; Rothbart, 1981). Infant shy/fearful temperament predicted decrement of attention scores. Novelty preference was also marginally related to shy temperament, but more strongly associated with low intensity pleasure, specifically enjoyment of physical contact with caregivers. Moreover, shy temperament continued to predict infant social understanding even when controlling for the effect of non-social intelligence (ASQ; Squires, et al., 2009). In our study, as in research with preschool-aged children (Wellman et al., 2011; Mink et al., 2014), shy, reticent temperament style is associated with social information processing, providing further evidence for continuity in individual differences in social cognition in early childhood.
