Suggestions that females are more sociable than males, however, seem to have little or no solid empirical basis. Reviews of gender differences have not supported the existence of the following two (stereotype) gender differences that are often mentioned: proximity seeking (girls do not appear to pursue contact with others any more than boys do) or sensitivity to social situations (Stockard & Johnson, 1992). Although female children are often described as more likely to “attach” themselves to their parents, there is little empirical evidence of significant differences in attachment behaviors of boys and girls (Lewis, 1987).
