2.1. Participants

98 Chinese children from a primary school from Southwest area participated in the study. Their age was ranged from 12 to 21 (M = 16.21, SD = 1.93).

2.2. Experimental Design

Multi-factor design was used, with game type and gender as independent variables and aggression as dependent variable. 2 (Game Type: violent vs. non-violent) × 2 (Gender: boy vs. girl) repeated two measures analysis of variance (ANOVA) was conducted with game type and gender as between-group factor, and goal word as within-group factor.

3. Results

In this study, we thought the RT of aggressive words was longer than that of nonaggressive words (compared to participants playing nonviolent games). Thus, we assumed each participant had an aggressively priming score (APS), which was RT values by subtracting nonaggressive words from aggressive words and divide by 2, and examined whether significant difference of APS found in group type.

A two-way analysis of variance (ANOVA) was carried out to examine the main effect of goal word on children’ aggression. There was no significant main effect of game type [F (1, 94) = 0.81, P > 0.05]. But we found a significant Game Type × Gender Interaction [F (1, 94) = 7.31, P< 0.01; see Table 1].

Simple effect analysis showed the average APS of boys playing violent and nonviolent games was significant higher than that of boys playing nonviolent games [F (1, 94) = 6.50, P < 0.05], but no significant APS was found in girls [F (1, 94) = 1.62, P > 0.05]. The results can be seen in Table 2.

4. Discussion

The study selected Chinese children as participants, which was different from prior researches (Bushman, 1995). In addition, we used emotional Stroop task to explore the gender differences in effects of violent computer games on aggression among children. It was showed that no significant main effect of game type on aggression, but a significant Game Type × Gender interaction was found, particularly aggression was significantly activated by violent games only among boys, but not among girls.
