#WORKING MEMORY SERIAL#
In the dual serial retrocuing (DSR) task, 2 items are initially presented as memoranda, followed by a retrocue that designates one the “prioritized memory item” (PMI equivalent to the “attended memory item” in previous publications) that will be interrogated by the impending probe.
Much of the empirical support for these models comes from tasks using a “retrocuing” procedure that allows for the controlled study of the back-and-forth switching of priority between memory items. State-based theoretical models of working memory posit that information can be held at different levels of priority in working memory, with information at the highest level of priority in the focus of attention (FoA) and the remaining information in a variously named state of “activated long-term memory” or “region of direct access”. Important for understanding the flexible control of behavior is understanding working memory: the mental retention of task-relevant information and the ability to use it to guide contextually appropriate actions.
