Irrelevant sensory stimuli interfere with working memory storage: Evidence from a computational model of prefrontal neurons
The encoding of irrelevant stimuli into the memory store has previously been suggested as a mechanism of interference in working memory (e.g., Lange & Oberauer, Memory, 13, 333–339, 2005 ; Nairne, Memory & Cognition, 18, 251–269, 1990 ). Recently, Bancroft and Servos (Experimental Brain Rese...

Summary: | The encoding of irrelevant stimuli into the memory store has previously been suggested as a mechanism of interference in working memory (e.g., Lange & Oberauer, Memory, 13, 333–339,
2005
; Nairne, Memory & Cognition, 18, 251–269,
1990
). Recently, Bancroft and Servos (Experimental Brain Research, 208, 529–532,
2011
) used a tactile working memory task to provide experimental evidence that irrelevant stimuli were, in fact, encoded into working memory. In the present study, we replicated Bancroft and Servos’s experimental findings using a biologically based computational model of prefrontal neurons, providing a neurocomputational model of overwriting in working memory. Furthermore, our modeling results show that inhibition acts to protect the contents of working memory, and they suggest a need for further experimental research into the capacity of vibrotactile working memory. |
