We have an open position for a Postdoctoral Associate to work on a perceptual-based assistive technology for age-related macular degeneration (AMD), with Dr.s Stephen Engel and Gordon Legge at the Department of Psychology, University of Minnesota. The position is a 12-month, 100% time appointment. The start date of this appointment will be July 1, 2020, though this is negotiable. It is renewable annually, contingent on performance and availability of funds.
The postdoctoral associate will play the key role in this project that tests a novel assistive technology for people with Age-Related Macular Degeneration (AMD). The goal is to evaluate "remapping" strategies that shift text away from a scotoma during reading, but using eye-tracking and real-time display updating. The project will test both normally sighted individuals and people with AMD.
Design of experiments(10% time) A series of experiments will test whether remapping text from outside a real or artificial scotoma benefits single word recognition and free reading performance. Details of design still need to be planned including full stimulus set, numbers of trials per condition, and details of specific remapping algorithm tested.
Implementation of experiments (20%) Computer code will be generated to run the experiments. This code controls and eye tracker and a visual display, and also gathers participant responses. Programming will be in MATLAB with special toolboxes to control the display and eye tracker.
Data Collection (30%) People with AMD and age-matched controls will be tested in a series of 6 visits each. Participants will be met in the lobby, taken to the CATSS lab for testing, and chaperoned through the experiment. Some responses may be collected by hand. Undergraduate research assistants will aid with the data collection and will be supervised by the applicant.
Data Analysis (20%) A number of statistical analyses will be programmed and run in the R data analysis language. Mixed effects linear models are the simplest of these, and will test whether remapping aids performance. Other analyses will test whether the size and shape of the scotoma affect the benefits of remapping.
Training and supervising data collection personnel (10%) Undergraduate research assistants will aid with the data collection and will be trained and supervised by the applicant on running the code, interacting with participants, recording results, and debriefing participants.
Writing up and presenting results (10%) Results will be submitted for publication in a scientific journal and will be presented at conferences, such as the annual meeting of The Association for Research in Vision and Opthalmology (ARVO)
We are looking for energetic candidates with a PhD in a sub-area of vision science.
Candidates should have a strong research background in one or more of the following topics: psychophysics, reading, age-related macular degeneration (AMD), eyetracking, and/or virtual reality.
Candidates should be skilled in programming for psychophysics.
PhD in Psychology or related field required
