Crossmodal Perception Of Object Shape: A Study On The Effect Of Modal Order On Successful Shape Recognition, Ashlyn Vale
Mahurin Honors College Capstone Experience/Thesis Projects
Visual and haptic (tactile) modes of perception, while occasionally exercised independently, most often occur concurrently. The degree to which the ordering of the two modes of perception affects successful recognition of three-dimensional shapes varies. Some have found that the cross-modal orders (vision followed by haptics or vice versa) produce equal performance (Caviness, 1964; Lacey, Peters, & Sathian, 2007; Norman et al., 2006), while other researchers found visual-haptic (VH) performance to be superior to haptic-visual (HV) performance (Davidson, Abbott, & Gershenfeld, 1974; Norman, Clayton, Norman, & Crabtree, 2008). The current experiment used an old-new recognition task (with cookie cutter stimuli). In …

Solving The Aperture Problem: Perception Of Coherent Motion, Lindsey Shain
Mahurin Honors College Capstone Experience/Thesis Projects
The aperture problem describes an effect by which a contoured stimulus, moving behind an aperture with both ends occluded, appears to move in a direction perpendicular to its own orientation. Mechanisms within the human visual system allow us to overcome this problem and integrate many of these locally ambiguous signals into the perception of globally coherent motion. In the current experiment, observers viewed displays composed of many straight contours, arranged in varying orientations and moving behind apertures. The total pattern of movement was consistent with a globally coherent trajectory. Observers were asked to estimate direction of global motion over a …
