Haptic memory found that haptic memory performance was significantly improved with the use of partial report procedures. This particular finding is consistent with more recent research by Gallace in 2008. Bliss et al. interpreted this difference in partial report versus whole report as a sensory form of memory for passively presented tactile stimuli with a high capacity and short duration. Additional support for the short duration of haptic memory comes from studies by Gilson and Baddeley in 1969. According to these studies, memory for stimuli applied to the skin is resilient for approximately ten seconds after removal of the stimulus, even when
