Gordon teaches a course on Perceptual Issues in Visual Impairment (Psy. 4-036) in alternate years. This course applies contemporary research findings to an improved understanding of the real-world abilities of visually impaired people. Each class session is divided between lecture and a hands-on lab experience with state-of-the-art adaptive technology. Topics include:
- Prevalence of low-vision and blindness
- Three dimensions of vision loss (acuity, contrast sensitivity, and visual field)
- Auditory and tactile perception
- Brain adaptation to vision loss
- Reading and low vision
- Braille reading
- Synthetic speech
- Adaptive technology for reading
- Space perception
- Navigational technology (ranging from canes to GPS)
- Driving with low vision
- Object recognition and face recognition
- Adaptive technology for computer access
- Recreational activities
This course is designed for a variety of audiences including Psychology majors, people with vision impairment, students with career interests in rehabilitation or eye care (special education, occupational therapy, physical therapy, pre-optometry, pre-med, or nursing), and professionals with related interests.
Gordon teaches a course on Visual Perception, it was last taught Fall 2020. The class includes discussion of visual illusions, vision in animals, a Wikipedia-style term paper and four lab sessions. The course introduces students to known principles and contemporary theories of visual perception. The main topics include:
- History of our understanding of light and vision
- Structures of the eye and their roles in vision
- Role of the retina in visual perception
- Color vision
- Pattern vision
- Depth, motion and space perception
- Object Recognition
- Impaired vision
The course is meant for advanced undergrads and grad students. Majors from many areas will find the course interesting, including psychology, neuroscience, biology, computer science, engineering, human factors, art, and design.
In recent years, Gordon has co-taught a class in the University’s Grand Challenges Curriculum (GCC) called The Human Experience of Sensory Loss.
Seeking equitable and effective solutions. This course focuses on the visual, auditory, and other sensory pathways that convey information about the world to the mind and brain. Millions of people worldwide experience deficits in sensory function that affect their quality of life. We focus on the characteristics of healthy sensory functioning as well as how sensory disorders can affect personal identity, impede information processing, and alter brain structure and function. The course addresses the demographics and risk factors for sensory disabilities, the implications of these disabilities for activities of daily living, the history of society’s response to sensory disability, as well as societal, ethical and personal attitudes toward sensory disabilities. The course also explores translational and applied approaches for addressing sensory disabilities. A major goal of the course is to view sensory function and impairment from multiple perspectives—cognitive science, neuroscience, medicine, engineering, society, consumers, ethics, and social justice.
The class welcomes both grad and undergrad students and is open to anyone interested in sensory disabilities.
From time to time, Gordon also teaches graduate seminars on special topics in visual perception (Psy. 8-031).
Gordon holds weekly lab meetings to discuss new findings from the lab and the research literature. Interested students may attend these meetings for class credit (Psy. 5-993.) These weekly meetings also include discussions of professional and ethical issues in science.
