title: Haptic face aftereffect.
abstract: Face aftereffects (FAEs) are generally thought of as being a visual phenomenon. However, recent studies have shown that people can haptically recognize a face. Here, I report a haptic, rather than visual, FAE. By using three-dimensional facemasks, I found that haptic exploration of the facial expression of the facemask causes a subsequently touched neutral facemask to be perceived as having the opposite facial expression. The results thus suggest that FAEs can also occur in haptic perception of faces.
