“…These group comparisons, however, may be confounded by the co-occurrence of more than one developmental trajectory representing both positive and negative change. For example, many children may be 'outgrowing' normative antisocial behaviours during this developmental period (Tremblay et al, 1999), at the same time that novel and more enduring problems are emerging in other children.…”

“…The few studies that have focused on physically aggressive behaviors during infancy and toddlerhood show that occasional use of aggression is common among preschool children (Dionne, Tremblay, Boivin, Laplante, & Pérusse, 2003;Goodenough, 1931;Tremblay et al, 1999;Tremblay et al, 2004). Moreover, two recent studies on the development of PA or conduct problems from toddlerhood to middle childhood support the possibility that aggression in kindergarten reflects the continuation of a behavior pattern that began in the preschool years.…”

The objectives of the study were to model the developmental trajectories of physical aggression (PA) from toddlerhood to pre-adolescence and to identify risk factors that distinguish typical (normative) from atypical developmental patterns. Ten cohorts of approximately 1,000 children (n = 10,658) drawn form a nationally representative (Canadian) sample were followed over 6 years. Using a group-based trajectory approach, we identified three groups of children with distinct developmental trajectories between 2 and 11 years of age. One third of the children (31.1%) followed a low desisting trajectory, reflected in infrequent use of PA in toddlerhood and virtually no PA by pre-adolescence. The majority of children (52.2%) followed a moderate desisting trajectory, reflected in occasional use of PA in toddlerhood and infrequent use by pre-adolescence. One sixth of the children (16.6%) followed a high stable trajectory of PA. Multivariate logistic regression indicated that children in the high PA trajectory group were more likely to be boys (OR: 1.67; CI: 1.5-1.87), from low income families (OR: 1.4; CI; 1.27-1.67), from families where the mother had not completed high school (OR: 1.20; CI: 1.05-1.38) and who reported using hostile/ineffective parenting strategies (OR: 1.16; CI: 1.14-1.18). In sum, the results indicate that the typical developmental pattern of PA was one of occasional and declining use over time. However, about one sixth of children, mostly boys from disadvantaged families, exhibited an atypical developmental pattern reflected in more frequent and stable use of PA. The results suggest that most children learned relatively well to inhibit PA by the end of childhood and that a minority failed to do so. Family risks traditionally found to be associated with antisocial behaviors during adolescence appear to interfere with the socialization of PA during early and middle childhood.

“…For instance, in one of the earliest account of infants' social interactions, Bridges (1933) documented the occurrence of "aggressive attacks" involving biting, hair-pulling and hitting at around 14-15 months of age (see also Brownlee & Bakeman, 1981;Bronson, 1981;Bühler, 1931Bühler, , 1935Dunn & Munn, 1985;Eckerman, Whatley & Kutz, 1975;Goodenough, 1931;Shirley, 1933). More recently, based on mothers' retrospective reports, Tremblay et al (1999) estimated the age of onset of some physically aggressive behaviors among children who manifested the behaviors in question at 17 months of age. The rate of onset was the steepest between 11 and 14-15 months of age, and appeared to level off thereafter.…”

“…Much of our knowledge on gender differences in aggressive behavior during infancy comes from small-scale studies that relied on nonprobability samples. Some studies have found that more boys than girls manifest aggressive behavior before two years of age (e.g., Fagot & Hagan, 1985;Hay, Castle & Davies, 2000;Tremblay et al, 1999), whereas others have found no gender differences (e.g., Hay, Castle & Davies, 2000;Holmberg, 1980;Shaw, Keenan & Vondra, 1994;Tremblay et al, 1999). To our knowledge, there are only three epidemiological surveys of physically aggressive behaviors in boys and girls under two years of age: the University of California Control Study (Macfarlane, Allen & Honzik, 1954), the 1956 Child Health Survey (Heinstein, 1969;Hornberger, Bowman, Greenblatt & Corsa, 1960), and the Québec Longitudinal Study of Child Development (Jetté & Des Groseilliers, 2000;Jetté, 2002;Plante, Courtemanche & Des Groseilliers, 2002).…”

There has been much controversy over the past decades on the origins of gender differences in children's aggressive behavior. A widely held view is that gender differences emerge sometime after 2 years of age and increase in magnitude thereafter because of gender-differentiated socialization practices. The objective of this study was to test for (a) gender differences in the prevalence of physical aggression in the general population of 17-month-old children and (b) change in the magnitude of these differences between 17 and 29 months of age. Contrary to the differential socialization hypothesis, the results showed substantial gender differences in the prevalence of physical aggression at 17 months of age, with 5% of boys but only 1% of girls manifesting physically aggressive behaviors on a frequent basis. The results suggest that there is no change in the magnitude of these differences between 17 and 29 months of age.
