The investigation of the relationship between behavioral variables such as videogame playing and aggression can be approached through either a quasi-experimental or a true experimental design. Both methodologies aim to uncover causal links, but they differ significantly in their structure and the strength of evidence they provide. For this study, an experimental design is preferable because it allows for more control over extraneous variables, thereby establishing a clearer causal relationship between the independent and dependent variables.

In developing this study, the independent variable would be the amount of time spent playing video games, while the dependent variable is the level of aggression exhibited by the participants. To operationalize these variables, the independent variable could be categorized into different levels—such as low, moderate, and high gaming duration—based on hours per week. The dependent variable would be measured through a validated aggression scale that captures physical and verbal aggression, ensuring reliable quantification of aggressive behaviors (Przybylski & Weinstein, 2019).

The hypotheses for this study are formulated as follows: the null hypothesis (H₀) posits that there is no effect of video game playing time on aggression levels; the alternative hypothesis (H₁) suggests that increased video game exposure is associated with higher aggression. Hypotheses in causal research typically fall into two categories: null hypotheses, which state that there is no effect or difference, and alternative hypotheses, which assert that there is an effect or difference. In this context, testing the hypotheses involves manipulating the independent variable—controlling the time spent playing video games—and observing subsequent changes in aggression, thus providing evidence for or against the cause-effect relationship.

The experimental method offers distinct advantages over a correlation design. Correlational studies can identify associations but cannot establish causality due to potential confounding variables and the inability to control the temporal sequence of events. Conversely, an experiment allows for the manipulation of the independent variable and the control of extraneous factors, enabling researchers to infer causality with greater confidence. Random assignment of participants to different levels of gaming exposure ensures that any differences in aggression are likely due to the manipulation rather than pre-existing differences. This control enhances internal validity and strengthens the evidence for a causal link.

Designing this study involves recruiting participants randomly from a target population, such as middle school children, to avoid selection bias. Participants would be assigned randomly to different groups—e.g., a control group with minimal gaming, and experimental groups with varying levels of gaming duration. These groups would then undergo intervention over a specified period, with consistent monitoring to ensure compliance. Pre- and post-intervention assessments of aggression using standardized scales would be conducted to measure changes attributable to the gaming exposure.

Furthermore, ethical considerations must be incorporated, ensuring informed consent, especially since minors are involved, and safeguarding their wellbeing. The study's validity could be bolstered by conducting follow-up assessments to examine the persistence of aggressive behaviors and to distinguish short-term effects from long-term implications. Employing a randomized controlled trial (RCT) structure maximizes the potential to draw valid causal inferences, providing valuable insights into the impact of video game exposure on aggression.
