Two experiments ( ) explored the effects of evaluative conditioning on mature brands. Explicit attitudes for mature brands were unaffected by evaluative conditioning. Experiment 1 showed, however, that evaluative conditioning changed implicit attitudes toward Coke and Pepsi. This occurred only for participants who initially had no strong preference for either brand. Contingency awareness was not necessary to change implicit brand attitudes. Experiment 2 showed that brand choice was related to the altered implicit attitudes, but only when choice was made under cognitive load. Implications of these data for evaluative conditioning specifically, and for consumer research in general, are considered. (c) 2008 by JOURNAL OF CONSUMER RESEARCH, Inc..

Research has shown that mindfulness can positively affect peoples’ lives in a number of ways, including relying less on previously established associations. We focused on the impact of mindfulness on implicit age and racial bias as measured by implicit association tests (IATs). Participants listened to either a mindfulness or a control audio and then completed the race and age IATs. Mindfulness meditation caused an increase in state mindfulness and a decrease in implicit race and age bias. Analyses using the Quad Model showed that this reduction was due to weaker automatically activated associations on the IATs.

Three studies examined the relation between dispositional optimism and gambling. In Study 1, optimists were more likely than pessimists to have positive gambling expectations and report maintaining these expectations following losses. They also were more likely to indicate that winning money was a primary motivation for their gambling. Study 2 demonstrated that pessimists but not optimists reduce their betting and expectations after poor gaming performance. Study 3 replicated this effect using a more controlled experiment and showed that after losing, optimists report remembering more near wins than do pessimists. Thus, all three studies suggest that optimists, more than pessimists, maintain positive expectations and continue gambling after experiencing negative gaming outcomes. The authors suggest that despite optimism's many benefits, there are common situations in which the pessimistic tendency to disengage is beneficial.

We conducted a preregistered multilaboratory project ( k = 36; N = 3,531) to assess the size and robustness of ego-depletion effects using a novel replication method, termed the paradigmatic replication approach. Each laboratory implemented one of two procedures that was intended to manipulate self-control and tested performance on a subsequent measure of self-control. Confirmatory tests found a nonsignificant result ( d = 0.06). Confirmatory Bayesian meta-analyses using an informed-prior hypothesis (δ = 0.30, SD = 0.15) found that the data were 4 times more likely under the null than the alternative hypothesis. Hence, preregistered analyses did not find evidence for a depletion effect. Exploratory analyses on the full sample (i.e., ignoring exclusion criteria) found a statistically significant effect ( d = 0.08); Bayesian analyses showed that the data were about equally likely under the null and informed-prior hypotheses. Exploratory moderator tests suggested that the depletion effect was larger for participants who reported more fatigue but was not moderated by trait self-control, willpower beliefs, or action orientation.
