One of the goals of vision science is to understand the nature of perception and its neural substrates. There are now many well established techniques and paradigms in both psychophysics and neuroscience to address problems in vision. However, knowing how to frame these questions for investigation is not necessarily obvious. Nervous systems present us with stunning complexity, and the purpose of perception itself is deeply mysterious. The goal of this seminar course is to step back and ask, what are the important problems that remain unsolved in vision research, and how should these be approached empirically? The course will consist of alternating weeks of discussion and guest lectures by vision scientists who will frame their views of the core unsolved problems. Interdisciplinary groups of students will devise a practical research plan to address an unsolved problem of their choice.

Instructors: Stan Klein, Jerry Feldman, Bruno Olshausen, and Karl Zipser

Weekly schedule:

Date Topic/Reading
Sept. 2 Introduction
Sept. 9 Methodology in vision science (Stan Klein)
  • Double-judgment psychophysics: problems and solutions pdf Read pp 1560-1567 This will give a glimpse into some of the issues involved with the relationship between detecting and identifying an object. The second part of the paper is more complicated.
  • Measuring, estimating, and understanding the psychometric function: A commentary pdf I (Stan Klein) was an editor of a special issue of "Perception & Psychophyics" and I wrote the summary article not only commenting on a number of the articles, but also trying to clarify some misunderstood aspects in the field.
  • Psychophysics : A Practical Introduction site This is the text by Kingdom and Prins that I've used when teaching psychophysics methods. I suggest reading Chapters 2 & 3. Some of the dichotomies in Chapter 2 are directly relevant to a number of unsolved problems in vision. Some might even be insoluble.

Feldman lecture: The neural binding problem(s) and related mysteries
As with many other “problems” in vision and cognitive science, “the binding problem” has been used to label a wide range of tasks of radically different behavioral and computational structure. These include a “hard” version that is currently intractable, a feature-binding variant that is productive routine science and a variable-binding case that is unsolved, but should be solvable. The talk will cover all these and some related problems that seem intractably hard as well as some that are unsolved, but are being approached with current and planned experiments.
