note

•  VWM tasks involves presenting two vibration patterns to a target (ex: the hand) separated by a variable ITI, and have do a same/different judgment on the patterns of vibrations (often in comparison to a target/probe pattern).  
• the method is useful for comparing results across methodologies, as the  feature of interest (vibration frequency) can be represented by a scalar value (i.e it is a simple measure of magnitude), and the neural firing that encodes the stimulus tend to have monotonic relationship (i.e. is linearly correlated) (pdf)

research suggests that VWM is part of a class of scalar WM tasks ( such as pure tone memory and memory for stim amplitude and duration) that share supramodal ( extends beyond a specific modality) neural coding in the sensory cortex higher cortical regions , and use the same prefrontal cortical region for storage.
