The use of a spoon for eating is one of the first tool-using skills acquired by most infants. The article provides a description and analysis of how the skill is built during the second year of life. A number of behavior categories were identified and measures were developed from a pilot study on a group of infants aged 10-58 months. Two groups of infants, aged 11 and 17 months, respectively, when the study began, were observed at monthly intervals over a 6-month period. Videotapes of mealtimes were subjected to detailed analysis that included extracting data on the following: hand use, grip pattern, visual monitoring, movements involved in the action, activities of the contralateral hand, spoon trajectory, temporal structure of the action, and so on. The emergence of competence was examined through comparisons within and between the groups. The acquisition of a tool-using skill is discussed in terms of the emergence of strategies to solve particular problems and the increasing consistency and reliability with which these are deployed.
