The synesthetic response, which is defined as the sensation synesthetes feel after observing someone else being touched, should feel like conscious experiences.

Three conditions must be met in order to confirm the presence of mirror touch synesthesia. Mirror-touch synesthesia may also co-occur with autism spectrum disorders. Their emotional experience of the observed touch may differ from the emotional experience of the person being touched ( may perceive a pleasant touch as unpleasant or vice versa). Mirror-touch synesthetes have higher levels of affective and pain empathy than those without the condition, though cognitive empathy differs from person to person. Mirror-touch synesthesia is found in approximately 1.6–2.5% of the general population. In addition, some mirror-touch synesthetes feel the phenomenon only in response to other humans being touched, while others also perceive it when animals or even inanimate objects are being touched.

This appears to be comparable to the projective versus associative distinctions found in other forms of synesthesia.

Some individuals have intense physical synesthetic responses to any physical touch they see, while others describe their experiences as feeling an 'echo' of the touch that they see. The severity of the condition varies from person to person. Synesthesia is usually a developmental condition however, recent research has shown that mirror touch synesthesia can be acquired after sensory loss following amputation. Synesthesia, in general, is described as a condition in which a concept or sensation causes an individual to experience an additional sensation or concept. For example, if someone with this condition were to observe someone touching their cheek, they would feel the same sensation on their own cheek. Mirror-touch synesthesia is a rare condition which causes individuals to experience a similar sensation in the same part or opposite part of the body (such as touch) that another person feels.
