Negative congruency effects: a test of the inhibition account.

Masked priming experiments occasionally revealed surprising effects: Participants responded slower for congruent compared to incongruent primes. This negative congruency effect (NCE) was ascribed to inhibition of prime-induced activation [Eimer, M., & Schlaghecken, F. (2003). Response faciliation and inhibition in subliminal priming. Biological Psychology, 64, 7-26.] that sets in if the prime activation is sufficiently strong. The current study tests this assumption by implementing manipulations designed to vary the amount of prime-induced activation in three experiments. In Experiments 1 and 3, NCEs were observed despite reduced prime-induced activation. Experiment 2 revealed no NCE with at least similar prime strength. Thus, the amount of prime activation did not predict whether or not NCEs occurred. The findings are discussed with regard to the inhibition account and the recently proposed account of mask-induced activation [cf. Lleras, A., & Enns, J. T. (2004). Negative compatibility or object updating? A cautionary tale of mask-dependent priming.

Effector-related sequence learning in a bimanual-bisequential serial reaction time task.

In a bimanual-bisequential version of the serial reaction time (SRT) task participants performed two uncorrelated key-press sequences simultaneously, one with fingers of the left hand and the other with fingers of the right hand. Participants responded to location-based imperative stimuli. When two such stimuli appeared in each trial, the results suggest independent learning of the two sequences and the occurrence of intermanual transfer. Following extended practice in Experiment 2, transfer of acquired sequence knowledge was not complete. Also in Experiment 2, when only one stimulus appeared in each trial specifying the responses for both hands so that there was no basis for separate stimulus-stimulus or separate response-effect learning, independent sequence learning was again evident, but there was no intermanual transfer at all. These findings suggest the existence of two mechanisms of sequence learning, one hand-related stimulus-based and the other motor-based, with only the former allowing for intermanual transfer.

The direction of affective priming as a function of trait anxiety when naming target words with regular and irregular pronunciation.

Results from an affective priming experiment confirm the previously reported influence of trait anxiety on the direction of affective priming in the naming task (Maier, Berner, & Pekrun, 2003): On trials in which extremely valenced primes appeared, positive affective priming reversed into negative affective priming with increasing levels of trait anxiety. Using valenced target words with irregular pronunciation did not have the expected effect of increasing the extent to which semantic processes play a role in naming, as affective priming effects were not stronger for irregular targets than for regular targets. This suggests the predominant operation of a whole-word nonsemantic pathway in reading aloud in German. Data from neutral priming trials hint at the possibility that negative affective priming in participants high in trait anxiety is due to inhibition of congruent targets.

Directionality of affective priming: effects of trait anxiety and activation level.

Among the most influential models of automatic affective processing is the spreading activation account (Fazio, Sanbonmatsu, Powell, & Kardes, 1986). However, investigations of this model by different research groups using the pronunciation task in an affective priming paradigm yielded contradictory results. Whereas one research group reported congruency effects, another obtained reversed priming effects (contrast effects), and still another found null effects. In Experiment 1, we were able to show an influence of trait anxiety on the direction of the affective priming effect. By using a multiple priming paradigm in Experiment 2, we were able to link the occurrence of reversed priming effects to increased levels of activation of affective representations. We propose that this relation might underlie the influence of trait anxiety on the direction of affective priming effects. Both experiments indicate that automatic evaluation in an affective network is substantially moderated by personality traits and activation level.
