视觉工作记忆中的搜索过程建模

Search in visual working memory (VWM) is an important process in everyday life, but it has so far not been investigated sufficiently using psychophysical and computational approaches. Here, we examine whether computational process models from the study of VWM and of visual search also apply to search in VWM. Participants performed a two-alternative VWM-based color localization task in which set size and color similarity were varied. We tested models with a resource-limited encoding stage and a Bayesian decision stage. We found that a variable-precision model fit the data well and that adding a
