Abstract

The time course of perception and retrieval of object features was investigated. Participants completed a perceptual matching task and 2 recognition tasks under time pressure. The recognition tasks imposed different retention loads. A stochastic model of feature sampling with a Bayesian decision component was used to estimate the rate of feature perception and the rate of retrieval of feature information. The results demonstrated that retrieval rates did not differ among object features if only a single object was held in memory. If 2 objects were retained in memory, differences among retrieval rates of features emerged, indicating that features that were quickly perceived were also quickly retrieved. The results from the 2-object retention condition are compatible with process reinstatement models of retrieval.

摘要

研究了物体特征感知和提取的时间进程。参与者在时间压力下完成了一项感知匹配任务和两项识别任务。识别任务施加了不同的保持负荷。使用具有贝叶斯决策成分的特征采样随机模型来估计特征感知率和特征信息提取率。结果表明,如果记忆中只保留一个物体,物体特征之间的提取率没有差异。如果记忆中保留两个物体,特征提取率之间就会出现差异,这表明快速感知的特征也能快速提取。双物体保持条件下的结果与提取的过程恢复模型一致。
