“…In the case of developmental psychology, evidence has suggested that even global aspects of normal child behaviors, such as temperament, systematically influence adult behavior (Thomas, Chess, & Birch, 1968). Similarly, more subtle, discrete child behaviors, such as vocalization (Gewirtz & Boyd, 1977), crying (Murray, 1979), smiling (Bates, 1976), activity level (Stevens-Long, 1973), aggression (Faggot, 1984), and speech (Bohannon & Marquis, 1977), have systematically influenced childadult behavior.…”
