likert element

The likert element is a specialized trial element for collecting likert ratings.

Syntax

<likert likertname>
/ anchors = [point = "label"; point = "label"; point = "label"]
/ anchorwidth = width
/ branch = (type.name.property, operator, value, next)
/ buttonvalues = [point="value", point="value", point="value"]
/ correctmessage = false or true(stimulusname, duration)
/ correctresponse = ("character", "character",...) or (scancode, scancode, ...) or (stimulusname, stimulusname, ...) or (mouseevent, mouseevent, ...) or (joystickevent, joystickevent, ...) or ("word, word, ...") or (keyword)
/ errormessage = false or true(stimulusname, duration)
/ fontstyle = ("face name", height, bold, italic, underline, strikeout, quality)
/ mouse = boolean
/ numframes = integer
/ numpoints = integer
/ position = (x, y)
/ posttrialpause = integer or variable
/ posttrialsignal = (modality, signal)
/ pretrialpause = integer or variable
/ pretrialsignal = (modality, signal)
/ response = responsename or timeout(milliseconds) or window(center, width, stimulusname) or responsemode
/ responseframe = integer
/ responseinterrupt = mode
/ responsemessage = (responsevalue, stimulusname, duration)
/ responsetime = integer
/ responsetrial = (response, trialname)
/ stimulusframes = [framenumber = stimulusname, stimulusname, ...; framenumber = stimulusname, ...] or [framenumber = selectionmode(stimulusname, stimulusname, stimulusname, ...)]
/ stimulustimes = [time = stimulusname, stimulusname, ...; time = stimulusname, ...] or [time = selectionmode(stimulusname, stimulusname, stimulusname, ...)]
/ timeout = integer or variable
/ trialcode = "string"
/ trialdata = [stimulusname, stimulusname, stimulusname, "string" "string", "string"]
/ trialduration = integer or variable

Remarks

The likert element controls the timing and the content of stimulus presentation as well as the appearance and behavior of the likert scale used to obtain ratings. Every time a likert element is executed, a line of data is written to the data file.

Examples

The following shows a five point likert scale at the bottom of the screen with evaluative labels:

<likert ratingquestion>
/ stimulusframes=[1=sometext]
/ anchors=[1="excellent"; 2="good"; 3="satisfactory"; 4="bad"; 5="aweful"]
/ position=(50, 90)
</likert>
