On the adaptive flexibility of evaluative priming

If priming effects serve an adaptive function, they have to be both robust and flexible. In four experiments, we demonstrated regular evaluative-priming effects for relatively long stimulus-onset asynchronies, which can, however, be eliminated or reversed strategically. When participants responded to both primes and targets, rather than only to targets, the standard congruity effect disappeared. In Experiments 1a–1c, this result was regularly obtained, independently of the prime response (valence or gender classification) and the response mode (pronunciation or keystroke). In Experiment 2, we showed that once the default congruity effect was eliminated, strategic-priming effects reflected the statistical contingency between prime valence and target valence. Positive contingencies produced congruity, whereas negative contingencies produced equally strong incongruity effects. Altogether, these findings are consistent with an adaptive-cognitive perspective, which highlights the role of flexible strategic processes in working memory as opposed to fixed structures in semantic long-term memory or in the sensorimotor system.     

On the relations between distinct aspects of psychological distance: An ecological basis of construal-level theory

Construal-level theory's basic assumption of a positive relationship between psychological distance and abstractness of mental representations presupposes a unitary distance construct. Although prior research testifies to convergent influences of temporal, spatial, social and reality (probability) distance, there is no direct evidence for the integration function of all four major distance aspects assessed within the same study with reference to the same target objects. Does high (low) distance in any aspect imply high (low) distance in all other aspects, or are discounting effects (e.g., high temporal distance rendering high personal distance obsolete) sometimes apparent in negative correlations? In pursuing this question, we obtained strong and regular positive correlations between all four distance aspects, across judges and judgment targets, regardless of whether freely construed future episodes or really experienced past episodes were judged. Existing ecological correlations seem to account for the positive relationship between time, space, probability and temporal distance.     

"Cognitive Resources and Leadership Performance": A Rejoinder

I feel very honoured by the distinguished group of colleagues who consented to comment on my paper. All raised thought-provoking questions which merit a detailed reply. I only regret that the strict space limitation imposed by the editor restricts my response to points on which my paper was unclear, and to a few important substantive issues. It would have been very satisfying to explore the many constructive and highly intriguing insights contained in the commentators' contributions.     

Mood and the generation effect

Three experiments address the assumptions, derived from a dual-force model, that positive mood supports assimilative (knowledge-driven) processes whereas negative mood supports accommodative (stimulus-driven) functions, and that mood-selective recall (mood congruency) is mainly a matter of assimilation. The generation-effect paradigm was borrowed from memory research to test these assumptions. In Experiment 1, the theoretical variable, degree of assimilation, was operationalised by the ease with which stimulus meaning could be generated from word fragments. In Experiment 2, self-generated stimuli (assimilation) were compared to experimenter-provided stimuli (accommodation). As predicted, positive mood supported assimilation which in turn enhanced mood-congruent recall. In Experiment 3, retrieval mood rather than encoding mood was manipulated. In this situation, positive mood facilitated the recall of all self-generated information, whether congruent or not. The empirical results are generally consistent with the predictions derived from the dual-force framework.
