Piglets在视频监视器上显示的异质干扰项中搜索符号目标。阶段1改变了目标标识和整体显示尺寸,从而建立了三个目标符号的差分辨别能力。第2阶段改变了这些目标在会话中的相对概率。研究结果表明,反应时较低,不仅当目标是更可辨别的,而且当它们是相对频繁的,这些效果并不依赖于较低频率的目标的可辨别性。III期试验设计相似,但偶尔提供两个靶点的选择试验。只有在这种试验中,鸟类才更有可能对更频繁的目标做出反应,前提是它也是最具辨别力的。这些数据与Guilford和Dawkins(1987)对搜索图像效应的重新解释的某些预测不一致。这些数据表明,检测和选择修改共同引发的预期和刺激驱动的知觉过程。
Pigeons searched for symbolic targets among heterogeneous distractor items displayed on a video monitor. Phase 1 varied target identity and overall display size, thus establishing differential discriminabilities of three target symbols. Phase 2 varied the relative probability of these targets within sessions. The findings showed that reaction time was lower not only when targets were more discriminable, but also when they were relatively frequent; these effects did not depend on the discriminability of the less frequent targets. Phase 3 was similar in design but provided occasional choice trials on which two targets appeared. The birds were more likely to respond to the more frequent target on such trials only if it was also the most discriminable. The data are not consistent with certain predictions from Guilford and Dawkins’ (1987) reinterpretation of effects attributed to search images. The data indicate that detection and choice are modified jointly by priming-induced expectancies and stimulus-driven perceptual processes.
