我们探讨是否可以观察到整体效应的非面部对象在新手作为一个结果的任务上下文。我们测量上下文引起的一致性效应的新对象（Greebles）在一个顺序匹配的选择性注意任务（复合任务）。当格式在研究被封锁，一致性效应观察到研究错位，但不研究对齐，条件（实验1）。然而，一致性效应观察到在所有条件下，当研究格式是随机的（实验2），揭示了存在某些试验类型（研究错位）在实验中可以诱导一致性效应。在一个双重任务中，Greebles的一致性效应诱导的试验中，一张脸是第一次编码，只有当它是对齐的（实验3）。因此，一致性效应可以通过在整个实验规模或单个试验中操作的上下文来诱导。使用复合任务来衡量整体处理的影响进行了讨论。
We explore whether holistic-like effects can be observed for non-face objects in novices as a result of the task context. We measure contextually-induced congruency effects for novel objects (Greebles) in a sequential matching selective attention task (composite task). When format at study was blocked, congruency effects were observed for study-misaligned, but not study-aligned, conditions (Experiment 1). However, congruency effects were observed in all conditions when study formats were randomized (Experiment 2), revealing that the presence of certain trial types (study-misaligned) in an experiment can induce congruency effects. In a dual task, a congruency effect for Greebles was induced in trials where a face was first encoded, only if it was aligned (Experiment 3). Thus, congruency effects can be induced by context that operates at the scale of the entire experiment or within a single trial. Implications for using the composite task to measure holistic processing are discussed.
