VSS…
I’ve got strong last-minute game. Editing my VSS stuff on the Uncanny Valley. I’ll post something here when I get back.
Fechner’s Aesthetics Revisited
Isn’t it beautiful? Gustav Fechner is widely respected as a founding father of experimental psychology and psychophysics but fewer know of his interests and work in empirical aesthetics. In the later 1800s, toward the end of his career,… Read More
Combinational Imaging: Magnetic Resonance Imaging and EEG Displayed Simultaneously
Before fMRI (Functional Magnetic Resonance Imaging) existed, I got to do this. We were one of the first labs to do this pre ‘functional’ functional imaging. Instead of volume rendering (which I would move on to Pixar to… Read More
The perception of surface orientation from multiple sources of optical information
The first piece of work in did in the “Todd Lab” at OSU. I had just come off five years at Pixar and a year back in grad school in the Architecture and Planning department. I wrote most of… Read More
Spring 2018 Vision in Animals, Humans and Machines — Final Projects
Vision in Humans, Animals and Machines is a seminar / hands-on course where we engage in a sort of comparative neuroscience with respect to how organic and inorganic systems ‘see’. Some things are hard for animals, some things… Read More
Spring 2018 Computational Methods — Final Projects
The goal of Computational Methods in Psychology and Neuroscience is to acquaint students with scientific computing, broadly speaking, but especially as it applies to psychology and neuroscience. Even so, it attracts students from a pretty wide swath of majors…. Read More
Perceiving Object Shape from Specular Highlight Deformation, Boundary Contour Deformation, and Active Haptic Manipulation
Haptic and visual ‘contours’ It is well known that motion facilitates the visual perception of solid object shape, particularly when surface texture or other identifiable features (e.g., corners) are present. Conventional models of structure-from-motion require the presence of… Read More
Haptic shape discrimination and interhemispheric communication
Touching. In three experiments participants haptically discriminated object shape using unimanual (single hand explored two objects) and bimanual exploration (both hands were used, but each hand, left or right, explored a separate object). Such haptic exploration (one versus… Read More
Creating noisy stimuli
So much noise. A method for creating a variety of pseudo-random `noisy’ stimuli that possess several useful statistical and phenomenal features for psychophysical experimentation is outlined. These stimuli are derived from a pseudo-periodic function known as multidimensional noise…. Read More
Perceptual representation of visible surfaces
What is a surface, anyway? Two experiments are reported in which we examined the ability of observers to identify landmarks on surfaces from different vantage points. In Experiment 1, observers were asked to mark the local maxima and… Read More
