was still unable to discriminate the forms explicitly. Our results suggest that V1 can process some
visual information, without the patient’s awareness.

The development of physical aggression and its impact on children’s school adjustment in early
childhood were examined. 148 children aged 3 were followed up till age 6 via natural observation,
interview and teacher rating. Remarkable developmental changes in children’s physical aggression
existed, with the peak being at age 4 and 5.5 respectively. In general, children aged 3-6 showed
stable individual differences in aggression, but boys manifested more variability. Different
trajectories could be identified in the development of children’s aggression. Children having a
higher level of physical aggression at age 4 possessed more negative attitudes towards
kindergarten at age 6.

This study distinguished three subtypes of social withdrawal by behavioral observation and
respectively explored their stability and adaptability from early to middle childhood. Totally 149
children’s social withdrawn behaviors and problem behaviors were assessed by observations or
questionnaires when the subjects were four and seven years old. All the three subtypes of social
withdrawal reduced rapidly in the three years. Reticence and passive-withdrawal were moderately
stable, while active-withdrawal was unstable. Only reticence significantly and positively
correlated to internalizing problem at both times. None subtype of social withdrawal at age 4
could significantly predict three-year-later behavior problems.
4099.4 Religiosity and motivations for having premarital sex among adolescents from a
Moslem country, Jas Jaafar, Malaysia
The study attempts to investigate the nature of adolescents' sexual activities and the reasons
behind engaging in premarital sex. Two hundred Malay Muslim adolescents completed a survey
regarding attitudes toward premarital sex, religiosity and psychosocial motives in engaging in sex.
The results are consistent with past research that show that a low degree of religiosity leads to a
more permissive attitude about sex. Despite the domination of traditional and religious values in
Malaysia, the adolescents still very much engage in premarital sex. Enhancement and intimacy
motives emerged as the primary reasons for having sexual intercourse.
