This longitudinal study was undertaken to examine the developmental progression of banging during the second half year of life. The second purpose was to determine if and when banging is used 'appropriately,' that is, as a function of object properties. Twenty infants were videotaped while presented with five pairs of objects, one pair at a time, for one minute each at monthly intervals. Object pairs were varied systematically along the hardness/sound potential dimension, to promote more or less banging. Results indicate that in some instances banging may go through a short period of indiscriminate use before it is applied appropriately, as with the cubes. In other instances, banging appears to be used selectively upon its emergence, as was the case with the dowel. Infants evidenced more banging of hard or rigid objects than of soft and flexible ones. An independent group of ten-month-olds exhibited the same discriminate banging, suggesting that the present findings may reflect developmental change rather than the effects of repeated testing / acase@tulane.edu
