ABSTRACT

In two studies, we examined the influence of behavioral inhibition system (BIS) and need for closure (NFC) on information processing in decision making. We expected that BIS would regulate behavior in a decisional context and that this relationship would be mediated by epistemic motivation expressed by NFC. In addition, drawing on contradictory findings in the literature on anxiety, NFC, and information processing, we investigated the moderating role of decision rules. The results supported our predictions. BIS was strongly and positively related to NFC, and through NFC it was related to decision-making style. Moreover, decision task characteristics moderated the relationship between NFC and decision making. When a task did not offer a confident decision rule, high NFC participants prolonged the information search more than low NFC individuals. However, when a reliable strategy was suggested, high NFC participants behaved in line with it. These results are discussed within an uncertainty management framework.

Mentions: In both FW and DW rounds bivariate correlations between BIS and the number of opened boxes and NFC and the number of opened boxes were not significant. To test the simultaneous effects of BIS and NFC on information search, we used the PROCESS program (Hayes 2013). We tested mediation models separately for the FW and DW rounds. We controlled for the order of rounds, but it was not significant; thus, this variable was dropped from the analysis. In the analysis for the FW round we excluded one case that had a much stronger influence on the model parameters than other cases (as indicated by Cook’s distance, studentized residuals, and DFFIT).1 In line with our hypothesis, BIS had a significant and positive effect on NFC (b = 0.50, SE = 0.08, β = 0.51, p < 0.001). NFC had a positive effect on the number of opened boxes (b = 2.70, SE = 1.15, β = 0.25, p = 0.02). Neither the direct effect of BIS on the number of opened boxes (b = −1.04, SE = 1.12, β = −0.10, p = 0.357), nor the total effect (b = 0.31, SE = 0.98, β = 0.03, p = 0.757) were significant. The entire model was marginally significant [F(2, 111) = 2.83, p = 0.063, R2 = 0.05]. More importantly, the indirect effect of BIS on the number of opened boxes estimated with 20,000 bootstrapped samples was significant [b = 1.34, 95 % CI (0.23, 2.83)], which indicates that BIS was related to information search through its impact on NFC. The mediation model is presented in Fig. 1. There were no significant effects of NFC and BIS on the number of opened boxes in the DW round.Fig. 1
