PSYC 3312 Lecture Notes - Lecture 12: Superior Olivary Complex, Medial Geniculate Nucleus, Sound Localization
Document Summary
3: sequence begins with cochlear nucleus and continues to the superior olivary nucleus in the brain stem. 7: visual capture/ ventriloquism effect occurs when sounds coming from one place appear to come from another place. The same neurons respond when visual stimulus originates from the same area: these multisensory neurons help to form a representation of space that involves hearing and sight, describe the use of echolocation by some blind people. For blind participants, visual cortex was activated, too: the visual cortex was strongly activated in echolocators, but not seeing, infant intermodal perception participants, speaker in the middle with two visuals on each side. Can they tell which sound goes with which sight. (happy talking or sad talking). Measuring percent of looking time at the correct display: method: preferential looking, dependent variable is percent looking at matching display, studies, bahrick: banging blocks and squishing sponges- sound difference, similar visual displays.
