Christie and Klein (1995) demonstrated that a familiar item (word) rapidly attracts attention when presented simultaneously with an unfamiliar item (nonword). However, this finding has never been replicated. The current study is an attempt at such a replication. Participants were presented a familiar word and unfamiliar nonword in the experimental condition. At varying times after stimulus onset one of the items moved, and the participant reported the direction of the movement. A replication of Christie and Klein would be obtained if performance was better for movement discrimination of the familiar item shortly after onset but not at later intervals. The original finding was replicated in fast participants while slower participants show a different effect. A potential individual difference variable is suggested to explain this difference between the fast and slow participants.
克里斯蒂和克莱因（1995年）证明，当一个熟悉的物品（单词）与一个不熟悉的物品（非单词）同时呈现时，熟悉的物品会迅速吸引注意力。然而，这一发现从未得到过重复验证。当前的这项研究就是一次进行此类重复验证的尝试。在实验条件下，向参与者呈现一个熟悉的单词和一个不熟悉的非单词。在刺激开始后的不同时间，其中一个物品会移动，参与者要报告移动的方向。如果在刺激开始后不久对熟悉物品的运动辨别表现更好，而在稍后的时间段则不然，那么就可以得到对克里斯蒂和克莱因研究结果的重复验证。快速反应的参与者重复了最初的发现，而反应较慢的参与者则表现出不同的结果。文中提出了一个潜在的个体差异变量来解释快速和慢速参与者之间的这种差异。
