Write a visual stimulus in 140-180 words.
Answers
Answer:
Visual stimuli are the most basic aspect of the experimental protocol, and often the most critical one as the choice of stimuli and of their parameters may define and limit the scope of your experiments. Psykinematix provides convenient tools to specify their spatial, temporal, and chromatic properties. Most stimuli properties can be specified with values, variables, or mathematical expressions.
Psykinematix offers the possibility of creating a large variety of basic visual stimuli:
Shape Stimuli
Grating Stimuli
Checkerboard Stimuli
Custom Stimuli
To create a Visual Stimulus, create a new single event in the "Experiment Designer" window, set its kind to "Visual Stimulus", and display its properties by clicking on the "Info" icon (or press Apple-I). Once a stimulus has been selected, changing it by clicking on other tabs is disabled unless the Control key is pressed simultaneously. This is to prevent accidental changes because stimulus settings are then reset to default.
