We examined the assumption that empathy, perceiving outgroup members as threat (i.e., perceived threat), self-esteem, feelings towards outgroups (e.g., feelings thermometer), and ingroup identification are mechanisms through which the relationship between attachment patterns and prejudice can be explained. Primed attachment security (vs. neutral prime), empathy, perceived threat, identification with Turkish identity and prejudice towards Syrian immigrants. Total number of 421 (19-76) Turkish citizens (323 female, 76.7%) with a mean age of 42.85 (SD= 12.65) participated. Participants were first attended to either secure or neutral priming conditions, answered felt-security questions as a manipulation check, and then they completed whole questionnaire. Felt-security levels were significantly higher for security priming group (t(419)= 11.816, p<.001) meaning that our priming manipulation activated secure attachment schemas successfully. Individuals in security priming condition indicated lower levels of perceived threat (M=3.23, SD= 1.26 ), in-group identification (M= 3.08, SD=1.01) and prejudice ( M=2.96, SD=.78) whereas they indicated higher levels of empathy (M= 3.61, SD =.41) and positive feelings towards Syrian Immigrants (M=5.14, SD= 2.39) when compared to their counterparts in neutral priming condition ( M= 3.55, SD= 1.20; M= 3.26, SD=1.05; M=3.51, SD= .51 and M= 4.61, SD= 2.43 respectively). We included, age, gender, education levels, income, satisfaction with life and exposure to Syrian immigrants as covariates. Priming, empathy, perceived threat, feelings towards outgroups and ingroup identification significantly predicted prejudice (R²= 0.61; F (12, 416) =52.54, p<.001)). Only age was a significant covariate. Perceiving Syrians as a threat (b =0.039, Cl[0.002, 0.810]) and feelings towards Syrian Immigrants ( b= 0.106, Cl[0.023, 0.193]) partially mediated the relationship between attachment security priming and prejudice towards Syrian immigrants. These findings suggest that enhancing felt security (e.g., by fostering attachment security) may lead to lower levels of perceived threat as well as more positive feelings toward outgroups and in-turn reduced prejudice.
