我们的目标是解决不同实验室先前实验之间的明显矛盾，使用双任务方法比较并发执行负荷对物品颜色或形状或其颜色形状组合的即时再认记忆的影响。两个实验的结果证实了先前的证据，即无关的注意负荷对特征记忆和特征绑定记忆的干扰是一样的。详细的分析表明，之前相互矛盾的证据来自于测量识别记忆的方式的局限性。本发现与早先的建议不一致，即特征绑定发生在多模式情节缓冲区Baddeley，(2000)内，并支持随后的描述，其中绑定在信息进入情节缓冲区Baddeley，Allen，&Hitch，(2011)之前自动发生。在方法论上，结果表明，不同的再认记忆绩效指标(A，d，校正再认)给出了主效应的趋同图景，但在检测交互作用方面不太一致。我们建议，在今后的研究中应考虑到测量识别可靠性的这一限制，以避免出现表面化而非真实化的复制问题。
We aimed to resolve an apparent contradiction between previous experiments from different laboratories, using dual-task methodology to compare effects of a concurrent executive load on immediate recognition memory for colours or shapes of items or their colourshape combinations. Results of two experiments confirmed previous evidence that an irrelevant attentional load interferes equally with memory for features and memory for feature bindings. Detailed analyses suggested that previous contradictory evidence arose from limitations in the way recognition memory was measured. The present findings are inconsistent with an earlier suggestion that feature binding takes place within a multimodal episodic buffer Baddeley, (2000) and support a subsequent account in which binding takes place automatically prior to information entering the episodic buffer Baddeley, Allen, & Hitch, (2011). Methodologically, the results suggest that different measures of recognition memory performance (A, d, corrected recognition) give a converging picture of main effects, but are less consistent in detecting interactions. We suggest that this limitation on the reliability of measuring recognition should be taken into account in future research so as to avoid problems of replication that turn out to be more apparent than real.
