Abstract
Vibrotactile Working Memory as a Model Paradigm for Psychology, Neuroscience, and Computational Modeling
Highlights
As might be deduced from the name, vibrotactile working memory is working memory for vibrational stimuli applied to the hand, most commonly to the dominant index finger
While it is theoretically possible that human subjects are verbally labeling the stimuli and storing that label, thereby converting the task from a vibrotactile to a verbal working memory task, there is no evidence of subjects using such a strategy
A recent human behavioral study implicitly tested this hypothesis, and found no evidence of verbal coding (Bancroft et al, under review). Research in both humans and nonhuman primates has identified a set of four regions critical for vibrotactile working memory: primary somatosensory cortex (SI), secondary somatosensory cortex (SII), medial premotor cortex (MPC), and prefrontal cortex (PFC; Romo and Salinas, 2003)
