Description: The aim of our study was to investigate whether social categorization would influence one’s decision to help others. The researchers hypothesized that the participants would be more likely to help if the victim is perceived as their in-groups. We performed a conceptual replication of Levine, et al. (2002) study by conducting a post-test only control group design to 46 Javanese female participants and randomly assigned them to control and experiment group. Participants in each group were asked to watch a robbery CCTV footage – a control group footage showed a Javanese female as a victim (N=23, M=29.6, SD=2.91), while participants in treatment group watched a footage whom the victim was a Chinese female (N=23, M=25.13, SD=5.6). After watching the video, participants filled out a questionnaire which asked; their subjective assessment of the dangerousness of the incident, their possible emotional responses, and their likelihood to interfere in the robbery incident. Bayesian Independent T-test was performed using JASP to test the hypothesis, and the posterior probability of the data provided a very strong support to the hypothesis (BF10=43.146). Our findings, therefore, showed that the hypothesis is 43 times more likely to be true compared to null hypothesis (no effect). Limitations, implications and future directions of our study are later discussed.
