Abstract

ABSTRACT Emotional reactions to unfamiliar objects and sensorimotor causality in infants The aim of the present study was to examine the relation between the development of sensorimotor causality and infants' emotional reactions to unfamiliar objects. Twenty-seven infants participated in five experimental sessions between the ages of 6 and 18 months. At each session, infants' visual fixations towards the objects were measured and their facial expressions of emotions were coded using max (Izard, 1983). In order to assess the development of sensorimotor causality, infants were also presented with a variety of cognitive tasks. A significant increase was observed in the duration of facial expressions of interest and of visual fixations towards the objects as infants reached Stages IV and V of sensorimotor causality. These changes in infants' reactions might be related to the transition from a magico-phenomenist notion of to a more objective notion.
