参与者被要求对一个独特颜色的目标进行扫视，同时忽略出现的干扰因素。结果为扫视编程的竞争性集成模型提供了证据，该模型假设内源性和外源性扫视在共同的扫视图中进行编程。该模型采用了横向交互结构，其中特定位置的扫视相关激活传播到邻近位置，但抑制远处位置。此外，还对扫视不应到达的位置进行自上而下、特定于位置的抑制。眼跳图中外源性和内源性激活的时间过程可以解释各种眼动数据，包括眼跳的端点、延迟和轨迹以及众所周知的全局效应。
Participants were required to make a saccade to a uniquely colored target while ignoring the presentation of an onset distractor. The results provide evidence for a competitive integration model of saccade programming that assumes endogenous and exogenous saccades are programmed in a common saccade map. The model incorporates a lateral interaction structure in which saccade-related activation at a specific location spreads to neighboring locations but inhibits distant locations. In addition, there is top-down, location-specific inhibition of locations to which the saccade should not go. The time course of exogenous and endogenous activation in the saccade map can explain a variety of eye movement data, including endpoints, latencies, and trajectories of saccades and the well-known global effect.
