Aging And The Perception Of Coherent Motion, Lindsey Marie Shain
Aging And The Perception Of Coherent Motion, Lindsey Marie Shain
Masters Theses & Specialist 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, younger and older observers viewed displays composed of either 64 or 9 straight contours, arranged in varying orientations and moving behind circular apertures. Because these lines moved behind apertures, their individual local motions were ambiguous with respect to direction …
Unimanual And Bimanual Haptic Shape Discrimination, Catherine Jane Dowell
Unimanual And Bimanual Haptic Shape Discrimination, Catherine Jane Dowell
Masters Theses & Specialist Projects
In the current study 24 younger adults and 24 older adults haptically discriminated natural 3-D shapes (bell peppers, Capsicum annuum) using unimanual (one hand used to explore two objects) and bimanual (both hands used, but each hand explored separate objects) successive exploration. Haptic exploration using just one hand requires somatosensory processing in only one cerebral hemisphere (the hemisphere contralateral to the hand being used), while bimanual haptic exploration requires somatosensory processing in both hemispheres. Previous studies related to curvature/shape perception have found either an advantage for unimanual exploration over bimanual exploration or no difference between the two conditions. In contrast …
Emotion Discrimination In Peripheral Vision, Hayley M. Lambert
Emotion Discrimination In Peripheral Vision, Hayley M. Lambert
Masters Theses & Specialist Projects
The recognition accuracy of emotion in faces varies depending on the discrete emotion being expressed and the location of the stimulus. More specifically, emotion detection performance declines as facial stimuli are presented further out in the periphery. Interestingly, this is not always true for faces depicting happy emotional expressions, which can be associated with maintained levels of detection. The current study examined neurophysiological responses to emotional face discrimination in the periphery. Two event-related potentials (ERPs) that can be sensitive to the perception of emotion in faces, P1 and N170, were examined using EEG data recorded from electrodes at occipitotemporal sites …
Perceptions Of Uncivil And Sexual Harassment Perceptions By Gender, Employment Status, And Likelihood To Sexually Harass, John Schroader
Perceptions Of Uncivil And Sexual Harassment Perceptions By Gender, Employment Status, And Likelihood To Sexually Harass, John Schroader
Masters Theses & Specialist Projects
This research examined gender and employment status (full-time worker or student) differences in perceptions of workplace sexual harassment and incivility. Previous and recent meta-analyses suggested small effects by gender. The current research introduced a method of measuring perceptions by forcing a choice of identifying a behavior as sexual harassment, incivility, or neither. The instrument was designed in this way to determine if small effects existed because males tended to have overlapping definitions of sexual harassment and incivility. Propensity to sexually harass was also measured. Results suggest no gender or employment status effects on the method, but propensity to sexually harass …
