Does Optic Flow Provide Information About Actions?, Hannah Masoner May 2022

Does Optic Flow Provide Information About Actions?, Hannah Masoner

Dissertations

Optic flow, the pattern of light generated in the visual field by motion of objects and the observer’s body, serves as information that underwrites perception of events, actions and affordances. This visual pattern informs the observer about their own actions in relation to their surroundings, as well as those of others. This study explored the limits of action detection for others as well as the role of optic flow. First-person videos were created using camera recordings of the actor’s perspective as they performed various movements (jumping jacks, jumping, squatting, sitting, etc.). In three experiments participants attempted to detect the action …

Are Neuronal Mechanisms Of Attentional Modulation Universal Across Human Sensory And Motor Brain Maps?, Edgar A. Deyoe, Wendy E. Huddleston, Adam S. Greenberg Jan 2022

Are Neuronal Mechanisms Of Attentional Modulation Universal Across Human Sensory And Motor Brain Maps?, Edgar A. Deyoe, Wendy E. Huddleston, Adam S. Greenberg

Kinesiology Faculty Articles

One's experience of shifting attention from the color to the smell to the act of picking a flower seems like a unitary process applied, at will, to one modality after another. Yet, the unique experience of sight vs smell vs movement might suggest that the neural mechanisms of attention have been selectively optimized to employ each modality to greatest advantage. Relevant experimental data can be difficult to compare across modalities due to design and methodological heterogeneity. Here we outline some of the issues related to this problem and suggest how experimental data can be obtained across modalities using more uniform …


Crossmodal Perception Of Object Shape: A Study On The Effect Of Modal Order On Successful Shape Recognition, Ashlyn Vale Jan 2022

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 …
