The exploratory behaviors of 60 5-month-old girls and boys were observed as they played with three unfamiliar toys and one familiar toy of their own during a laboratory session. Infants were seated at a table on the lap of an assistant. Each toy was placed on the table and remained there for 2 min after the infant first touched it. Frequency and duration of visual fixation on the toy, hand contact with the toy, five categories of lateralization, and eight categories of handling behaviors were measured. On the whole, the exploratory behaviors of girls and boys were not markedly different. However, girls spent more time than boys did in simultaneous hand contact with and visual fixation on their own familiar toy, whereas boys made more frequent contact with the familiar toy without visual fixation. In addition, boys displayed, overall, more tapping behaviors, and girls, more pinching and object-displacement behaviors. Girls and boys did not differ in manual lateralization. Results are discussed in reference to infants' rate of development, motor activity level, and girls' and boys' reactions to novelty.
