The role of lateral masking in more rapid performance improvement with peripheral than with central precuing was investigated. A peripheral precue to the inside of the target location provided less masking at zero precue-target delay than a precue to the outside (experiment 1) or a precue involving a partial target at the target location (experiment 2). There was no significant interaction between precue-target delay and precue type in a comparison of inside precues and precues involving a briefly-brightened box around the target location, although overall performance was significantly poorer with the latter (experiment 3). Performance was better at short precue-target delays with inside precues than with central precues (experiment 4), yet it did not improve significantly more rapidly. Minimizing lateral masking with peripheral precues thus eliminates the dramatic performance improvement sometimes observed across short precue-target delays, causing performance to be consistently better than with central precues across these delays.
研究了外周线索化比中央线索化能更快速地改善表现时，侧向掩蔽所起的作用。在零线索-目标延迟时，目标位置内侧的外周线索比外侧线索（实验1）或目标位置处涉及部分目标的线索（实验2）提供的掩蔽更少。在比较目标位置内侧线索和目标位置周围有一个短暂变亮框的线索时，线索-目标延迟和线索类型之间没有显著交互作用，尽管总体表现上后者显著更差（实验3）。在短线索-目标延迟时，目标位置内侧线索的表现优于中央线索（实验4），但改善速度并没有显著更快。因此，通过外周线索最小化侧向掩蔽消除了有时在短线索-目标延迟中观察到的显著的表现改善，使得在这些延迟期间表现始终优于中央线索。
