Perceiving affordances : Visual guidance of stair climbing

TL;DR: It is concluded that perception for the control of action reflects the underlying dynamics of the animal-environment system.
Journal ArticleDOI

Prevalence of BRCA1 and BRCA2 Gene Mutations in Patients With Early-Onset Breast Cancer

TL;DR: Mutations in the BRCA1 and BRCa2 genes make approximately equal contributions to early-onset breast cancer in Britain and account for a small proportion of the familial risk of breast cancer.
Journal ArticleDOI

Visual guidance of walking through apertures: body-scaled information for affordances.

TL;DR: This study videotaped large and small subjects walking through apertures to determine empirically the critical aperture-to-shoulder-width ratio (A/S) marking the transition from frontal walking to body rotation and tested the hypothesis that perceptual judgments of "passability" are based on intrinsic or body-scaled information specifying aperture width as a ratio of the observer's eyeheight.
Journal ArticleDOI

Optic flow is used to control human walking

TL;DR: It was found that people walked in the visual direction of a lone target, but increasingly relied on optic flow as it was added to the display, thereby allowing humans to have robust locomotor control under varying environmental conditions.
