“…Naturalistic observations of children's emotional expressivity are quite inconsistent in their conclusions concerning gender differences, again possibly due to a failure to study situational context systematically The context in which emotional expressions have been observed varies widely from study to study Cender differences in newborn and infant emotional expression have been studied m the presence of siblings and mothers (Jacobs & Moss, 1976, Malatesta & Haviland, 1982, Moss, 1967, in the process of separating from mothers, with and without a barrier (Fiering & Lewis, 1979, Coldberg & Lewis, 1969, Jacklin, Maccoby, & Dick, 1973, Robson, Pederson, & Moss, 1969, Skann, 1977, Trause, 1977, Van Lieshout, 1975, in the presence of unfamiliar adults (Kagan 1978, Lewis & Weinraub, 1979, and in the absence of any interpersonal or cognitive interactions (Feldman, Brody, & Miller, 1980, Osofsky & O'Connell, 1977, Phillips, King, & DuBois, 1978, Yang & Moss, 1978, Zeskind & Lester, 1978 Cender differences m preschoolers' emotional expressions have been studied in the context of interactions with peers (Camras, 1977, Landreth, 1941 and parents (Golding, 1982) As previously noted, differences m the situational context may help to account for the wide vanations in results concerning gender differences in emotional expressiveness For example, Landreth (1941) found that in an observational study of a preschool, girls cried more frequently as a result of accidental injury than did boys, whereas boys cried more frequently as a result of interactions with objects or conflicts with adults Many studies of gender differences m infant emotional expressiveness are studies of temperament, that is, the infants' reactive tendencies to external and internal stimulation Cognitive developmental theorists hypothesize that gender differences in temperament should influence and be influenced by the quality of mother-infant interactions, which would in turn differentially affect the emotional development of each sex Some reviews of infant temperament research indicate no evidence for any gender differences (Rothbart & Derryberry, 1981), vet Haviland and Malatesta (1981) review several studies which in...…”
