A significant face-inversion effect was found during tactile exploration of faces, indicating that orientation impacts haptic face recognition. This effect was not observed with non-face objects like teapots.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Sensory Perception

Background:

  • The face-inversion effect, where upside-down faces are harder to recognize, is well-established in visual perception.
  • It remains unclear if this effect extends to tactile face recognition, which relies on sequential exploration.

Purpose of the Study:

  • To investigate the presence of a face-inversion effect during tactile exploration.
  • To determine if haptic face processing is sensitive to object orientation.

Main Methods:

  • A haptic version of the inversion paradigm was employed using 3-D clay facemasks and control objects (teapots).
  • Blindfolded participants performed a same/different task on upright and inverted facemasks and teapots.

Main Results:

Related Experiment Videos

  • A significant inversion effect was observed for facemasks regarding accuracy.
  • No significant inversion effect was found for the control teapot objects.

Conclusions:

  • The findings suggest that tactile face recognition is susceptible to the face-inversion effect.
  • Sequential manual exploration of faces is influenced by orientation, similar to visual processing.
