  • Title: Practise strengthens haptic capture.
    Author: Misceo GF, Plankinton BW.
    Journal: Can J Exp Psychol; 2009 Jun; 63(2):113-23. PubMed ID: 19485602.
    Abstract:
    When do haptic estimates of discordant visual-haptic size capture vision? Observers looked at a square through a minifying lens (50%) whilst they simultaneously touched the square from below through a hand-concealing cloth. Their subsequent match of the square's size, rendered by touching a set of comparison squares, was haptically biased when they practised estimating the square's size (Experiment 1, N = 72), when they actively explored rather than passively touched the square (Experiment 2, N = 24), but not when they were uninformed before inspecting the square that they would estimate its size (Experiment 3, N = 36). Evidently, the haptic exploratory strategies occasioned by the practise influenced the integration of the felt size and the seen size by weighing the haptic input more than the visual input, and this weight shifting manifested itself by strengthening haptic capture.
