Abstract EN
Generic properties of curvature representations formed on the basis of vision and touch were examined as a function of mathematical properties of curved objects.
Virtual representations of the curves were shown on a computer screen for visual scaling by sighted observers (experiment 1).
Their physical counterparts were placed in the two hands of blindfolded and congenitally blind observers for tactile scaling.
The psychophysical data show that curvature representations in congenitally blind individuals, who never had any visual experience, and in sighted observers, who rely on vision most of the time, are statistically linked to the same mathematical properties of the curves.
The perceived magnitude of object curvature, sensed through either vision or touch, is related by a mathematical power law, with similar exponents for the two sensory modalities, to the aspect ratio of the curves, a scale invariant geometric property.
This finding supports biologically motivated models of sensory integration suggesting a universal power law for the adaptive brain control and balance of motor responses to environmental stimuli from any sensory modality.
