Investigating The Roles Of Mechanoreceptive Channels In Tactile Apparent Motion Perception: A Vibrotactile Study, Phill Kim, Philip Servos Dr.
Theses and Dissertations (Comprehensive)
Tactile apparent motion (TAM) is a perceptual phenomenon in which consecutive presentation of multiple tactile stimuli creates an illusion of motion. Employing a novel tactile display device, the Latero, allowed us to investigate this. The current study focused on the Rapidly Adapting (RA) channel and Slowly Adapting I (SAI) channel on the index finger. The experiment implemented vibrotactile masking stimuli to target the mechanoreceptive channels with the goal of gaining better insight into the involvement of mechanoreceptive channels in the perception of TAM. Masking stimuli were used because previous studies have used them to differentiate between different channels; a …
Comparison Of The Sensitivity Of Yes/No And Forced Choice Associative Recognition, Garrett Schliewinsky
Comparison Of The Sensitivity Of Yes/No And Forced Choice Associative Recognition, Garrett Schliewinsky
Theses and Dissertations (Comprehensive)
Yes-no (YN) and forced choice (FC) associative recognition tasks were compared across three experiments to test the varying effects of familiarity. Schliewinsky and Hockley (2016) previously found a discrimination advantage for FC tasks over YN tasks when word pairs were familiarized. The present research is a continuation to further explore the effects of increased familiarity. Experiment 1 manipulated the familiarity of individual items in the word pairs. No discrimination advantage for the FC condition over the YN condition was found when only item familiarity was increased, emphasizing the importance of associative information for accurate associative recognition. There was, though, a …
Dynamic Balance Control And Segmental Orientation While Listening During Walking: Effects Of Age And Hearing Loss, Sin Tung Lau
Dynamic Balance Control And Segmental Orientation While Listening During Walking: Effects Of Age And Hearing Loss, Sin Tung Lau
Theses and Dissertations (Comprehensive)
Dynamic control of balance changes with age and changes with declines in sensory and cognitive abilities. For instance, emerging, yet robust associations between hearing loss and poor mobility have been described and yet the mechanism underlying these associations remains unknown. It could be that age-related declines in hearing ability result in different kinematic strategies when having to walk and listen at the same time (e.g. head and body orienting responses toward sounds) and/or that declines in hearing result in increased cognitive load during listening, at the detriment to mobility-related performance. Therefore, this thesis sought to better characterize these associations by …
