Adults' causal representations integrate information about predictive relations and the possibility of effective intervention; if one event reliably predicts another, adults can represent the possibility that acting to bring about the first event might generate the second. Here we show that although toddlers (mean age: 24 months) readily learn predictive relationships between physically connect...

A confirmatory factor analysis was used to examine the latent structure of inhibitory processes in day-care center children aged 24-32 months and in preschool children aged 36-48 months. The best fit to the data for the younger sample was a single undifferentiated inhibition factor model; in older ch...

Information on child-rearing attitudes and beliefs was obtained from mothers of the children. Chinese toddlers were significantly more inhibited than their Canadian counterparts. Inhibition was associated positively with mothers' punishment orientation and negatively with mother...
