摘　　要：采用2(眼跳方向)×3(实验范式)×4(任务指导语)的完全被试内实验设计研究任务指导语和实验范式对朝向和反向眼跳的影响效应。结果:(1)朝向眼跳潜伏期显著快于反向眼跳,且不受实验范式的影响;(2)在朝向眼跳任务中,空白范式下的延迟型指导语导致眼跳潜伏期延长;(3)在反向眼跳任务中,空白和重叠范式下延迟型指导语潜伏期最长;零范式下速度型指导语的潜伏期较短;(4)空白范式下的反向眼跳错误率显著低于重叠范式和零范式,反向眼跳潜伏期显著短于后两种范式。实验结果支持眼跳竞争模型。In order to explore the effects of task instruction and experimental paradigm on saccade performance, a 2x 3x4 three-factor within-subjects experimental design was adopted. Results： （1） The latency of prosaccade was sig- nificantly faster than that of antisaccade under any experimental paradigm; （2） In prosaccade performance only delay instruction resulted in prolonged latency significantly; （3） In antisaccade performance the effects of task instruction in different experimental paradigm were not in full accord. （4） The error rate of antisaccade in Gap paradigm was significantly lower than that in overlap and step paradigm, and latency paradigm was outstandingly faster than others. These results support the Competitive Race of antisaccade in Gap Model.
