我们使用空间负启动（SNP）范式来检查婴儿和成人的视觉选择性注意力，并使用眼球运动作为运动选择测量。在 SNP 中，当先前被忽略的位置成为要选择的目标时，对其的反应就会受到损害，从而提供抑制选择的措施。每次试验均由一次启动和一次探测组成，刺激间隔 (ISI) 间隔为 67、200 或 550 毫秒。在巅峰时期，一个目标伴随着一个干扰物。在探测器中，目标出现在先前被干扰物占据的位置（忽略重复）或另一个位置（对照）。成年人在所有三种 ISI 条件下均表现出 SNP 效应，与对照试验相比，在忽略重复的情况下产生较慢的眼跳潜伏期。仅在 550 和 200 ms ISI 条件下对婴儿获得的 SNP 效果。这些结果表明视觉选择的重要发展植根于新兴的抑制机制。 (C) 2004 Elsevier B.V. 保留所有权利。
We used a spatial negative priming (SNP) paradigm to examine visual selective attention in infants and adults using eye movements as the motor selection measure. In SNP, when a previously ignored location becomes the target to be selected, responses to it are impaired, providing a measure of inhibitory selection. Each trial consisted of a prime and a probe, separated by 67, 200, or 550 ms interstimulus intervals (ISIs). In the prime, a target was accompanied by a distractor. In the probe, the target appeared either in the location formerly occupied by the distractor (ignored repetition) or in another location (control). Adults exhibited the SNP effect in all three ISI conditions, producing slower saccade latencies on ignored repetition versus control trials. The SNP effect obtained for infants only under 550 and 200 ms ISI conditions. These results suggest that important developments in visual selection are rooted in emerging inhibitory mechanisms.
