Crossmodal Perception Of Object Shape: A Study On The Effect Of Modal Order On Successful Shape Recognition, Ashlyn Vale
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 …
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 …
Short-Term Visual Deprivation, Tactile Acuity, And Haptic Solid Shape Discrimination, Charles E. Crabtree
Short-Term Visual Deprivation, Tactile Acuity, And Haptic Solid Shape Discrimination, Charles E. Crabtree
Masters Theses & Specialist Projects
The visual cortex of human observers changes its functionality in response to visual deprivation (Boroojerdi et al., 2000). Behavioral studies have recently documented enhanced tactile abilities following a short period of visual deprivation (Facchini & Aglioti, 2003; Weisser, Stilla, Peltier, Hu, & Sathian, 2005). The current study investigated the effects of visual deprivation on two unique tactile tasks. While Facchini and Aglioti observed significant effects of visual deprivation, neither Wong, Hackeman, Hurd, and Goldreich (2011) nor Merabet et al. (2008) observed these effects. Corroborating these more recent results, no difference in grating orientation discrimination performance was observed between the sighted …
The Influence Of Spatial Distance Priming On Test Anxiety And Judgments, Eric R Raap
The Influence Of Spatial Distance Priming On Test Anxiety And Judgments, Eric R Raap
Masters Theses & Specialist Projects
This paper examined the effects of distance priming on test anxiety and judgment. Research suggests that individuals’ perceived distance can impact their affect and judgments, which sheds light on the principle of “distance equals safety” (Williams & Bargh, 2008). Taking an exam invokes both cognitive and emotional anxiety, such as worry, panic, and tension. It is hypothesized that the distance priming may reduce test anxiety—particularly, the emotionality aspect—as well as perceived test difficulty. The results showed that, counter to the hypotheses, there was no significant difference among the three priming groups in their emotional test anxiety or perceived test difficulty. …
