SURF: Announcements of Opportunity
Below are Announcements of Opportunity posted by Caltech faculty and JPL technical staff for the SURF program. Additional AOs for the Amgen Scholars program can be found here.
Specific GROWTH projects being offerred for summer 2017 can be found here.
Students pursuing opportunities at JPL must be U.S. citizens or U.S. permanent residents.
Each AO indicates whether or not it is open to non-Caltech students. If an AO is NOT open to non-Caltech students, please DO NOT contact the mentor.
Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions! Remember: This is just one way that you can go about identifying a suitable project and/or mentor.
Announcements for external summer programs are listed here.
|Project:||Multisensory Integration: Perceptual Illusions|
|Disciplines:||Computation and Neural Systems, Neuroscience|
|Mentor:||Shinsuke Shimojo, Professor, (BBE), firstname.lastname@example.org|

Many neuroscience concepts are based on the prediction of future perception or on decisions based on prior brain states or stimulus presentations. However, the brain can also process information retroactively, such that later stimuli impact conscious percepts of the stimuli that have already occurred (called “postdiction”). Well-known effects such as apparent motion, the flash lag effect, and the cutaneous rabbit effect are examples of visual or tactile stimuli that influence perception retroactively. Postdictive effects have thus far been mostly unimodal (that is, based on only one sense such as vision or audition), and the models for postdiction have accordingly been limited to early sensory regions of one modality. We are studying multimodal illusions in which audition instigates postdictive changes in visual perception, thereby broadening the potential for postdictive phenomenon and generating new neural models for its occurrence.
In this project we will study behavioral illusions that are both multisensory and postdictive in nature. This investigation will help elucidate how the senses work together to generate a temporal flow of sensory processing in the brain.
|Description:||The SURF student will help design psychophysical experiments on multisensory perception, code experiments in Matlab, and test them on human subjects.|
