Erratum 4. Results

In this study, we use RT to aggressive words as a dependent variable. A three-way analysis of variance (ANOVAs) was performed to examine the main effect of stimuli type on aggression. As expected, the significant main effect of stimuli type was found after violent stimuli exposure [F (1,176) = 21.87, P < 0.001; see Table 1], and that participants who exposed to violent stiumuli displayed higher AAS than those who exposed to nonviolent stimuli. Further, a significant stimuli type × gender interaction was found [F (1, 176) = 20.58, P < 0.001], and further simple effect analysis indicated that AAS of males was significantly smaller when exposing to violent stimuli than when exposing to non-violent stimuli [F (1, 176) = 79.02, P < 0.01], but no significant difference for AAS offemales [F (1, 176) = 0.01, P > 0.05; see Table 2)]. However, no significant movie type × aggressive personality interaction was found [F (2, 176) = 1.05, P > 0.05; see Table 1].

 5. Discussion 5.1. Violent Stimuli Exposure Could Significantly Elevate Aggression

Overall, we found that violent stimuli significantly activated aggression among undergraduates. This result supported our first hypothesis, and it was correspo- ndent with the previous study [11]. Some experts assumed contextual factors were responsible for aggressive behavior after viewing violent movies [2].

5.3. Violent Stimuli Exposure Did Not Induce Significant Differences in Aggressive Personality

In this study, there was no significant difference in aggressive personality after viewing violent stimuli. This result was not in agreement with hypothesis 3. In the process of adaptability on campus, aggressive paersonality might not the real reason to cause students show more aggression. Hence, educators can ignore the aggressive personality of students after viewing violent stimuli. The aggressive personality might not be a necessary individual factor to impact levels of aggression among Chinese undergraduates after exposing to violent pictures.
