Detecting Changes In Auditory Events, Rachael B. Peck
Detecting Changes In Auditory Events, Rachael B. Peck
Masters Theses, 2010-2019
Change deafness is defined as the failure to detect the source of an above-threshold change in an auditory scene. A new paradigm recently demonstrated the phenomenon under analogous conditions to its visual counterpart, change blindness (Hall, Peck, Gaston, & Dickerson, 2015). This investigation examined the use of the paradigm through two experiments which involved the same four simultaneously presented events. Experiment 1 distributed events across a virtual 120º on the azimuth while the target event oscillated across a 60º space throughout each trial. Listeners were instructed to identify the target as soon as possible. Target rate of change was manipulated …
The Effect Of Global And Local Processing In The Attentional Blink, Ashley Kalavritinos
The Effect Of Global And Local Processing In The Attentional Blink, Ashley Kalavritinos
Senior Honors Projects, 2010-2019
The attentional blink (AB) is an individual’s inability to perceive the second of two targets presented in a rapid serial visual presentation (RSVP). The constructs of global and local attention have been a principle concern in modern psychology. The perception of an object as an overall form is referred to as the global aspect, while the separate parts compose the local aspect. The purpose of this study was to explore whether the following factors affect the characteristics of an individual’s AB: (1) When target one (T1) and target two (T2) were the same or different letters (2) Whether T1 was …
The Effect Of Auditory Stimuli On Visual Time-To-Contact Perception, Chelsea L. Rugel
The Effect Of Auditory Stimuli On Visual Time-To-Contact Perception, Chelsea L. Rugel
Senior Honors Projects, 2010-2019
Previous research has demonstrated that auditory and visual stimuli have individual effects on the accuracy of a person’s estimation of time-to-contact (TTC), the time at which two objects collide. Prior findings also suggest that there is cross-modal interference between vision and audition; however, this phenomenon has never been studied in a TTC situation. (Driver & Spence, 1998; Ichikawa & Masskura, 2006; Roseboom, Kawabe, & Nishida, 2013) In this study we attempted to fill in this research gap by examining the effect of auditory speed cues over visual speed cues in a two-dimensional TTC scenario, and by determining if an object’s …
