beginresponsetime attribute

Specifies the time, relative to the beginning of the stimulus presentation sequence, at which Inquisit begins registering responses.

Member of

<likert> <openended> <trial>

Syntax

/ beginresponsetime = integer expression

Parameters

integer expression The time in milliseconds, or -1 to recognize responses made at any point during the trial.

Remarks

The beginresponsetime attribute enables tasks that allow subjects to respond before or during the presentation of stimuli. By default, Inquisit recognizes responses that occur after the stimulus presentation sequence, and responses given during the presentation are ignored. A value of -1 tells Inquisit to recognize responses given at any point during the trial. Response latency is measured relative to the point specificed by beginresponsetime, which is the beginning of the trial if set to -1.

Examples

The following trial presents a sequence of stimuli, allowing the subject to respond at any point during the sequence:

<trial mytrial>
/ stimulustimes = [0=sometext1; 100=sometext2; 200=sometext3; 300=sometext4; 400=sometext5]
/ beginresponsetime = 0
/ validresponse = (" ")
</trial>

The following trial presents a sequence of stimuli, allowing the subject to respond at any point after the 3rd stimulus is presented but not before:

<trial mytrial>
/ stimulustimes = [0=sometext1; 100=sometext2; 200=sometext3; 300=sometext4; 400=sometext5]
/ beginresponsetime = 200
/ validresponse = (" ")
</trial>
