We conducted a longitudinal study of the meal-time behaviors of an infant to examine the development of object manipulation. At the age of 8 months, 27 days, this infant began to touch containers. Analysis 1 revealed different types of manipulation. Analysis 2 examined the manipulations involved in placing food or cutlery in containers and investigated the process of using manipulations in accordance with the different meanings of various containers. Upon reaching 10 months and 30 days of age, the infant began accidentally putting food into a container and playing with it both in containers and on the table. When the infant reached 1 year, 1 month, and 22 days of age, we began to observe a variety of ways in which containers were utilized, such as putting food in containers, returning food to the containers in which it had been served, placing cutlery into containers, moving food between containers, moving food on a plate, inserting and removing food from the mouth, taking and returning food, and placing food into the infant’s own dish.
