Flexibility of representational states in working memory
The relationship between working memory (WM) and attention is a highly interdependent one, with evidence that attention determines the state in which items in WM are retained. Through focusing of attention, an item might be held in a more prioritized state, commonly termed as the focus of attention (FOA). The remaining items, although still retrievable, are considered to be in a different repre...
متن کاملTrisecting representational states in short-term memory
The ability to hold information briefly in mind in the absence of external stimulation forms the core of much of higher-order cognition. This ability is referred to as short-term memory (STM). However, single-term labels such as this belie the complexity of the underlying construct. Here, we review evidence that STM is an amalgamation of three qualitatively distinct states. We argue that these ...
متن کاملRepresentational pseudoneglect in an auditory-driven spatial working memory task.
Two experiments explored lateralized biases in mental representations of matrix patterns formed from aural verbal descriptions. Healthy participants listened, either monaurally or binaurally, to verbal descriptions of 6 by 3 matrix patterns and were asked to form a mental representation of each pattern. In Experiment 1, participants were asked to judge which half of the matrix, left or right, c...
متن کاملEditorial: Representational states in memory: where do we stand?
One key debate in memory research centers around the problem of representation. How is information represented in memory and how do the principles that govern memory representations change across the short and long term? One class of memory models (e.g., Baddeley and Hitch, 1974) characterized separate memory stores for information represented over the short-term from those of more permanent an...
متن کاملPERK Regulates Working Memory and Protein Synthesis-Dependent Memory Flexibility
PERK (EIF2AK3) is an ER-resident eIF2α kinase required for memory flexibility and metabotropic glutamate receptor-dependent long-term depression, processes known to be dependent on new protein synthesis. Here we investigated PERK's role in working memory, a cognitive ability that is independent of new protein synthesis, but instead is dependent on cellular Ca2+ dynamics. We found that working m...
