jspsych-text plugin

This plugin is for showing instructions and other basic HTML content to the subject.


This table lists the parameters associated with this plugin. Parameters with a default value of undefined must be specified. Other parameters can be left unspecified if the default value is acceptable.

Parameter Type Default Value Description
text string undefined A string containing HTML formatted text (no HTML code is necessary, but it is allowed).
cont_key array or 'mouse' [ ] This array contains the keys that the subject is allowed to press in order to advance to the next trial. Keys can be specified as their numeric key code or as characters (e.g. 'a', 'q'). The default value of an empty array means that all keys will be accepted as valid responses. If the value of 'mouse' is used, then clicking the mouse will advance to the next trial.

key_press numeric Indicates which key the subject pressed. The value is the numeric key code corresponding to the subject's response.
rt numeric The response time in milliseconds for the subject to make a response. The time is measured from when the stimulus first appears on the screen until the subject's response.
