The increasing aggressive behavior argues the researchers because of the violent video games that the children play. The authors conduct a meta analytic review of the exiting research literature on video games to show that violent video games exposure would result in physiological arousal and also aggression related thoughts. In the meta analytic review, researchers made use of literature from scholarly databases such as Psyc INFO. Relevancy criteria and coding frame criteria were both developed. Meta-analysis was done by means of Statistical Analysis system SAS and fixed and random effects models. In terms of aggressive behavior, it is noted that there is some form of associations in the results. The results indicate that when children are exposed to violent video games, then there are good chances that they would be involved in extreme levels of aggression.
The article of Anderson et al (2008) attempts to investigate whether the exposure to violent video games will result in increased physical aggression for youth. The authors objective here was to test for both the United States (where the violence is high) and Japan where the violence is relatively low. A primary research study is conducted here where three independent samples and 181 Japanese students (in the first run) and 1050 students (in the second run) were selected. The third sample was 364 students from the United States. The results suggest that the students who played a lot of violent games become more aggressive. Playing violent games is hence a significant risk factor.
These articles support one another. In the first study, many variables in relation to aggressive behavior were studied. It was found out that in the first study, the study is not quite specific. It was seen that different studies from different years and research focus was in fact selected. On the other hand, the second study is one that is a primary investigation. So the focus of investigation is more specific to a problem. It can be seen from the second study that primary investigation also supports the Meta analytic review.
These are two very different styles of research. The first article is a meta analytic review. It is the nature of the meta analytic review to make use of study materials that are pre-formed. These are studies that are conducted by other researchers and hence there is a chance that there could be some amount of bias in the study. On the other hand, the second research is a primary study and hence the author has applied the exact variables that they want to research on. I believe I would trust the primary study more than the secondary study, as the primary study is more current and hence the data would be more valid and pertinent for current researchers. On the other hand, the secondary study might not be current and data might not be reliable.
