VisionLab Single Site License with Hardware Kit

VisonLab™ is a set of user-modifiable vision demonstrations and experiments, many of which are presented in Stereoscopic. It is a teaching tool designed for Introductory and Experimental Psychology; Sensation and Perception.

It is flexible and easy to use with a menu-driven program that permits you to set up a teaching laboratory in as little as half an hour.

There are two parts. The first part consists of demonstrations and the second consists of psycho-physical experiments.

DEMONSTRATIONS

A partial list is illustrated below and a complete list in the Full Product Description Document.

• Illusions: Muller-Lyer, Ponzo, Poggen-dorff, Color Assimilation
• Apparent and relative motion: Phi phenomenon, motion recruitment, motion in depth, cycloid motion
• Stereo forms: disparity-biased Necker cubes, tilted and rotated bars, Random dot stereograms: static, dynamic and moving
• After-effects: McCollough, motion
• Kinetic depth: rotating sphere, Saturn illusion, structure from motion
• Subjective contours: static, stereo apparent motion, and rotating subjective squares
• Equiluminance: heterochromatic flicker, various illusions, square and circle interposition
• Fusional / rivalrous stimuli
• Tachistoscopic demos: Sperling partial report, metacontrast masking
• Reading demos

Each of the demonstrations has a dialog box associated with it permitting the user to modify key parameters. This illustrates a guiding principle behind VisionLab. The demonstrations should be more than simple objects that students can see in books; rather they should be dynamic modifiable objects so that students may experiment on them.

PSYCHOPHYSICAL EXPERIMENTS

The user may select from a variety of psychophysical and statistical methods to conduct experiments, collect and analyze data. The psychophysical are: methods of adjustment, constant stimuli, staircase, quest, and signal detection.
