Participants wielded a cross-shaped cane parallel to their sagittal plane. This cane was held with a weighted branch above (high-weight condition) or below the fist (low-weight condition). The task required participants to determine, by exploring the surface with the cross-shaped cane, the critical inclination corresponding to a fall on the slanted surface. Three weight conditions, high-weight (HW), low-weight (LH) and no-weight (control), were used to change the perceived orientation of the arm and thus evaluate the role of this postural information. Results showed an effect of the weight factor with a pattern of results consistent with the assumption that postural information of the arm was involved in haptic perceptual judgment of posturability on a slanted surface.Lire moins >
