Infant responses and the physical environment

A longitudinal study of infants ( n =23) from 6 to 13 months was made to explore infants' responses to objects high on complexity and responsiveness compared to low-scored ones, and whether the high-scored objects were preferred. Further, it was explored to what extent individual differences of the infants represent a source of variation. The results showed that more than 50% of the total variance was accounted for by differences in object qualities, and about 25% by individual differences. High-scored objects were significantly more often preferred compared to low-scored ones irrespective of age.
