其他摘要

PURPOSE: Conflict adaptation (CA) has been used to study the transfer of cognitive control across consecutive trials, in which the conflict effect is reduced when the previous trial also contains conflict with regards to stimulus-responses compatibility (SRC). Previous studies have found that cognitive control is modality-specific, such that the CA effect appears only when adjacent trials contain conflicts from the same modality, but is absent when the conflicts are from different modalities. However, the modality-specific effect may have been confounded by factors such as negative priming, feature integration and contingency learning. Therefore we investigated whether or not cognitive control could transfer across auditory and visual conflicts when the other factors were controlled.
METHODS: A modified audio-visual color-word Stroop task (Figure.1) was conducted, in which participants were asked to respond to a visual stimulus, with conflict coming from either the same or a different modality. The experimental sequences were pseudo-random, so that the task- relevant and irrelevant stimuli were never repeated in adjacent trials.
RESULTS: We conducted three-way repeated measures analyses of variance of Switch (same or different modalities) × Previous Congruency × Current Congruency and found marginal 3-way interaction. Further analyses revealed that the 2-way interaction between Previous Congruency and Current Congruency (CA effect) was only significant in the modality-repetition condition, but not in the modality-alternation condition.
CONCLUSIONS: The results supported that cognitive control served in a modality-specific fashion to resolve conflicts across visual and auditory modalities. Moreover, the modality-specific effect of cognitive control should be taken into account in theories of cognitive control.
