最近使用波斯纳线索范式探索返回抑制的研究似乎表明，在检测和辨别任务中，非空间特征的重复对线索相关的促进性和抑制性后效的调节是不同的。由于线索与检测任务中的最终反应无关，但与辨别任务中的最终反应平行(不是正交的)，因此尚不清楚不同的结果模式是由决策的复杂性(检测与区分)还是由可能或可能不会从一个线索重复到另一个目标的特征的任务相关性造成的。在实验1(检测任务)和实验2(辨别任务)中，我们在前人工作的基础上复制了前面的模式：在检测任务中没有早期特征重复益处，但减少了特征不匹配试验的IOR；在辨别任务中，早期特征重复受益较大，但特征匹配对后期IOR没有影响。在实验3(辨别任务)中，我们采用了“正交线索”的方法：在被辨别的维度(形状)上，不存在从线索到目标可以重复或不重复的特征(颜色)。结果的模式与在检测任务中观察到的非常相似。这些结果表明，调节促进和抑制效应的不是任务，而是重复特征的任务关联性。这些发现大体上与定向感抑制后遗症的习惯化解释一致，但不排除其他机制的贡献。
Recent research using the Posner cuing paradigm to explore inhibition of return seems to suggest that repetition of a nonspatial feature modulates cue-related facilitatory and inhibitory aftereffects differently in detection and discrimination tasks. Because the cues were unrelated to the final response in the detection task but parallel to (not orthogonal with) the final response in the discrimination task, it is unclear whether the different patterns of results were caused by the complexity of the decision (detection vs. discrimination) or by the task relevance of the feature that might or might not repeat from cue to target. Using a paradigm modeled on previous work, in Experiment 1 (detection task) and 2 (discrimination task) we replicated the previous patterns: No early feature repetition benefit but reduced IOR for feature mismatch trials in the detection task; and large early feature repetition benefit but no effect of feature match upon the later IOR in the discrimination task. In Experiment 3 (discrimination task), we used an “orthogonal-cuing” method: the feature (color) that could repeat or not from cue to target wasnoton the dimension being discriminated (shape). The pattern of results was very similar to what is observed in detection tasks. These results demonstrate that it is not the task but the task relevance of the repeating feature that modulates facilitation and inhibition effects. The findings are generally consistent with a habituation account of the inhibitory aftereffects of orienting but do not rule out the contribution of other mechanisms.
