Observations were made of infant caregivers in four child care centers to determine which stimulation acts (verbal and physical contacts) were provided for the infants and with what frequency of occurrence. It was hypothesized that walking infants would receive more stimulation acts than non-walkers. Nineteen caregivers were observed interacting with 29 infants between the ages of 6 months and 21 months. Each caregiver was observed for five 10-minute episodes at the child care center where he or she worked. The interactions between infants and caregivers were recorded and later coded into predefined categories of stimulation acts. A frequency distribution of the stimulation acts showed that language associated acts occurred most frequently. The amount of time caregivers spent in the provision of the acts is also included in the results. An analysis of variance showed there was no significant difference between the frequency of stimulation acts provided to walking and non-walking infants. (Author/RH)
