Internal motivation to respond without prejudice and automatic egalitarian goal activation

Past research has shown that people who are motivated primarily by their internalized beliefs to respond without prejudice are less likely to show implicit forms of racial bias (e.g., Devine, P. G., Plant, E. A., Amodio, D. M., Harmon-Jones, E., & Vance, S. L. (2002). The regulation of explicit and implicit race bias: The role of motivations to respond without prejudice. Journal of Personality and Social Psychology, 82, 835-848). We tested the idea that such individuals inhibit implicit race bias by automatically activating egalitarian goals. Study 1 showed that participants high in internal motivation but low in external motivation (i.e., primary internal) displayed more egalitarianism, but only after they had been subliminally exposed to African American faces. Study 2 showed that primary internal motivation was associated with lower levels of automatic stereotype activation and this effect was mediated by egalitarian goal activation. These results provide converging evidence that the relationship between primary internal motivation and low levels of implicit bias stems from the activation of egalitarian goals. We discuss the implications of these findings for efforts to reduce cognitive and affective forms of implicit racial bias.     

Cultural differences in unrealistic optimism and pessimism: the role of egocentrism and direct versus indirect comparison measures

Recent research has raised questions regarding the consistency of unrealistic optimism and related self-enhancing tendencies, both within cultures and across cultures. The current study tested whether the method used to assess unrealistic optimism influenced cross-cultural patterns in the United States and Japan. The results showed that the direct method (a single comparison judgment between self and peers) produced similar patterns across cultures because of cognitive biases (e.g., egocentrism); specifically, participants were unrealistically optimistic about experiencing infrequent/negative events but pessimistic about experiencing frequent/ negative events. However, the indirect method (separate self- and peer judgments) produced different patterns across cultures because culturally specific motivational biases emerged using this method; specifically, the U.S. sample was more unrealistically optimistic than the Japanese sample. The authors discuss how these results might influence the interpretation of previous findings on culture and self-enhancement.     

The role of the dorsal striatum and dorsal hippocampus in probabilistic and deterministic odor discrimination tasks

Three experiments explored the contribution of the cortico-striatal system and the hippocampus system to the acquisition of solutions to simultaneous instrumental odor discriminations. Inactivation of the dorsal striatum after rats had reached criterion on a three problem probabilistic set of discriminations--A (80%) vs. B (20%), C (67%) vs. D (33%), E(67%) vs. F(33%)--impaired test performance and disrupted performance when the rats were tested with novel cue combinations (C vs. F and E vs. D), where control animals chose C and F. In contrast, inactivating the dorsal hippocampus enhanced performance on this task and on a deterministic discrimination A (100%) vs. B (0%). These results are consistent with the complementary learning systems view, which assumes that the cortico-striatal and hippocampal system capture information in parallel. How this information combines to influence task performance depends on the compatibility of the content captured by each system. These results suggest that the trial-specific information captured by the hippocampal system can be incompatible with the across-trial integration of trial outcomes captured by the cortico-striatal system.     

Is there a baby in the bathwater? Maybe: some methodological issues for the de novo protein synthesis hypothesis

The de novo protein synthesis hypothesis has a long history and will no doubt continue to influence research. Yet, the primary behavioral evidence for this claim continues to come from studies in which amnesia is produced by broad scale protein synthesis inhibitors such as anisomycin. What is remarkable is the uncritical acceptance of the idea that because anisomycin is a protein synthesis inhibitor then it must have produced amnesia because it prevented translation. Several viable alternative interpretations of such experiments are discussed here and it is concluded that there is nothing to be gained by the continued use of broad-scaled antibiotics to address this hypothesis. Moreover, this approach cannot answer two critical and related questions - why must new proteins be synthesized and what are they? A focus on specific proteins such as those synthesized locally and upregulate the translation of other proteins may be a promising approach to answering these questions.     

What's in it for Me? Motivational Differences between Farmers' Subsidised and Non‐Subsidised Conservation Practices

Through nature conservation practices, farmers can strongly enhance nature quality and biodiversity in rural areas. In this paper, the social psychological underpinnings of farmers' nature conservation practices are investigated using the Theory of Planned Behavior, to which the concepts of self‐identity and personal norms were added. A distinction is made between nature conservation practices done on a non‐subsidised basis and nature conservation practices for which farmers receive some form of remuneration from the Dutch government. Eighty‐five arable farmers participated in our survey. Results show that our model explains more variance in the intention to perform non‐subsidised than subsidised nature conservation practices. Also, the concepts of self‐identity and personal norms appear to be related to the intention to perform non‐subsidised, not subsidised conservation.
