responsemessage attribute

The responsemessage attribute specifies a feedback stimulus to be shown after the subject gives the specified response on a trial.

Member of

Syntax

/ responsemessage = (responsevalue, stimulusname, duration)

Parameters

responsevalue	A valid response value for the trial. See validresponse for possible response values.
stimulusname	The name of a stimulus element defined elsewhere in the script.
duration	An integer or property specifying duration in milliseconds for which the stimulus is displayed on the screen. A value of "0" indicates that stimulus should be displayed for the remaining duration of the trial.

Remarks

The stimulus is shown for duration milliseconds. If the duration is 0, the stimulus is presented for the duration of the posttrialpause. This attribute can be listed multiple times in a given trial to specify different feedback stimuli for different responses.

Examples

The following trial displays a positive stimulus for 1000 ms if the response is "a" and a negative stimulus for 1000 ms if the response is "b":

<trial mytrial>
/ stimulusframes = [1=sometext]
/ validresponse = ("a", "b")
/ responsemessgae = ("a", positivetext, 0)
/ responsemessgae = ("b", negativetext, 0)
/ posttrialpause = 1000
</trial>

The following trial displays a positive stimulus for 1000 ms if the response is values.responseleft and a negative stimulus for 1000 ms if the response is values.responseright:

<trial mytrial>
/ stimulusframes = [1=sometext]
/ validresponse = (values.responseleft, values.responseright)
/ responsemessgae = (values.responseleft, positivetext, 0)
/ responsemessgae = (values.responseright, negativetext, 0)
/ posttrialpause = 1000
</trial>
