Ten-year-olds' free time activities -- as well as whom they spend their free time with -- are linked to gender development, academic interests, school grades and self esteem at age 12, a Penn State study shows.
In addition, the study suggests that time spent in same-sex activities may advantage boys but disadvantage girls during middle school.
"The amount of time girls spent with other females predicted declines in qualities such as sensitivity and kindness as well as declines in self esteem but time with males, particularly male peers, predicted increases in such qualities among boys," says Susan McHale, professor of human development and family studies and leader of the study.
The study is detailed in a paper, "Links Between Sex-typed Time Use in Middle Childhood and Gender Development in Early Adolescence," published in the September issue of the journal Developmental Psychology. McHale's coauthors are Ji-Yeon Kim, graduate student; Shawn Whiteman, graduate student; and Ann C. Crouter, professor of human development and family studies.
The researchers collected data from 103 girls and 97 boys over two years. At the start of the study, each child was about 10 years old, the firstborn in their family and had at least one younger sibling. Each year, the researchers conducted home interviews with the children and their parents followed, during the next two to three weeks, with seven evening telephone interviews.
During the calls, the children were asked how much time they spent in 26 free-time activities. The researchers then classified the activities as masculine or feminine depending on whether girls or boys favored them. The researchers do not suggest that activities are sex-typed in any absolute sense, only that the classification represents the worldview of the children in the study.
The children's interest ratings led to 11 activities classified as feminine (read books or magazines, write letters, stories or poems, art activities, knitting, sewing, crocheting or other handicrafts, play a musical instrument, dance, gymnastics, swim, play with pets/animals, gardening, play with dolls/stuffed animals) and five activities classified as masculine (sports, hunting and fishing, building with blocks, Legos or models, play with toy vehicles and play with action figures).
