Sequential modulation of distractor-interference produced by semantic generalization of stimulus features.

摘要: Sequential modulations of distractor-related interference (i.e., reduced congruency effect after incongruent as compared to congruent predecessor trials, a.k.a. Gratton effect) have been taken reflect conflict-induced attentional focusing. To dismiss an alternative interpretation based on integration and retrieval low-level features, it is important exert experimental control stimulus response feature sequences. This has achieved by considering only trials associated with complete changes. Furthermore, distractors from two different perceptual dimensions, such location shape, combined in the same experiment investigate question specificity vs. generality conflict adaptation. With this method sequence can be exerted, principle, without disregarding data repetition trials. However, may insufficient when distractor dimensions overlap semantically. In experiments we found evidence consistent assumption that semantic generalization between a presented at left-sided shape pointing left, yield between-dimension effect. These findings raise doubts about inferring generalized adaptation semantically related are used.
