Title:  Touching on face space: Comparing visual and haptic processing of face shapes


Abstract:

The idea that faces are represented within a structured face space (Valentine, 1991) has gained considerable experimental support both from physiological and perceptual studies. Recent work has also shown that faces can even be recognized haptically, that is from touch alone. Although there is some evidence for congruent processing strategies in visual and haptic processing of faces, the question of how similar the two modalities are in terms of face processing remains open. Here, we address this question by asking whether there is evidence for a haptic face space and, if so, how it compares to visual face space. For this, we created a physical face space consisting of 6 laser-scanned individual faces, their morphed average, 50%-morphs between two individual faces, as well as 50%-morphs of individual faces with the average, resulting in a set of 19 faces. We then gathered either visual or haptic pairwise similarity ratings of tangible 3D face shapes. Multidimensional scaling analyses showed that both modalities extracted perceptual spaces that conformed to critical predictions of the face space framework, hence providing hl{support for similar processing of complex face shapes in haptics and vision}. Despite their overall similarity, however, there were also systematic differences between the visual and haptic data. These differences are discussed in the context of face processing and complex shape processing in vision and haptics.
