size_weight_illusion | R Documentation |
A dataset containing data from 28 healthy controls and one patient, DF, with visual form agnosia (inability to perceive the form of objects) from bilateral lesions to the lateral occipital complex. The size-weight illusion occurs when a person underestimates the weight of a larger item when compared to a smaller of equal weight (Charpentier, 1891). From these data, one can assess the magnitude of the illusion for patient DF by comparison to age-matched controls under visual and kinaesthetic cue conditions. The measure of the size-weight illusion is a scaled measure expressing the number of grams weight difference perceived per cubic cm of volume change (Hassan et al, 2020).
