What we typically refer to as “the sense of touch” is what we will call “active” or “haptic” touch. This refers to touch that involves some movement. This movement can be voluntary, exploratory movements of the hands and other sensory surfaces involved in touch, or it can also refer to experiences generated by objects moving against a stationary body. In most cases, haptic touch will involve the engagement of kinesthesis (awareness of movement) and proprioception (awareness of bodily position). Some apply the term “haptic” for any touch that involves the activation of (the physiologically and functionally distinct) kinesthetic or proprioceptive systems (e.g., Loomis and Lederman 1986). Touch mediated entirely through the skin will be referred to as “cutaneous touch”. The term “tactual” will be used as a broad term to refer to any form of touch experience (so it’s used in the same way that “auditory” and “olfactory” are used for hearing and smell ). For the features and objects made available through touch the term “tangible” will be used (again, in the same way as “visible” is used for for features and objects made available by vision).
