Stimulus Display

Description

A stimulus display device. At present, MWorks always creates one (and only one) of these per experiment, regardless of whether the experiment file defines one. By including a definition in your experiment file, you can change the display’s default background color.

Signature

iodevice/stimulus_display

Required Parameters

background_color

Example:0.5,0.5,0.5

The background color, expressed as a comma-separated list of red, green, and blue components with values between 0 and 1 (inclusive)

Optional Parameters

announce_stimuli_on_implicit_updates

Default:YES

Controls the announcement of stimuli during “implicit” display updates (i.e. updates requested by running dynamic stimuli and not triggered by an explicit Update Stimulus Display action). If set to NO, then implicit updates will not generate #announceStimulus events, and #stimDisplayUpdate events for implicit updates will contain only the number of stimuli displayed (in place of the usual list of stimulus parameters).

alt

Alternative device to use if this one fails to initialize (e.g. because the required hardware is not available). If #allowAltFailover is set to 0 or false, this parameter is ignored.
