likert element

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

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. Likert supports responding by keyboard (number and arrow keys to select a response, and ENTER key to submit it) or mouse (click the response button to submit a response). The default is mouse input.

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="awful"]
/ position=(50, 90)
</likert>
