Note: this task does not currently work in Internet Explorer or Edge browsers Responses can be made with mouse clicks or touch responses. Some of the sentences in this example use words with multiple meanings, so the participant must select the picture that reflects the meaning of the word that is consistent with the sentence context. The task is to indicate which picture is most closely related to the meaning of the sentence. Participants hear a sentence and then see two pictures. Tasks created with jsPsych, running on JATOS – Picture selection – <<) is presented and the participant must indicate the direction of the middle arrow by pressing one of two keys on the keyboard. On each trial, a sequence of 5 arrows (e.g. If all 3 responses for a given list length are incorrect, then the task stops. The list lengths start at 3 digits and increase to the next list length if at least one of the responses was correct. The task contains list lengths 3-10 for forward span and 3-8 for backwards span. Participants see a sequence of digits, presented one at a time, and then have to recall the number sequence in the same order. Note: this task does not currently work in Internet Explorer or Edge browsers due to compatibility issues with HTML5 audio. Two words are presented in succession, and the participant’s task is to indicate (as quickly and accurately as possible) whether or not the meanings of the two words are related. Note: this task does not work in Internet Explorer or Edge browsers due to compatibility issues with HTML5 audio. For instance, after hearing the word ‘kitten’, one might type ‘cat’, ‘pet’, ‘whiskers’, etc. BACKWARD DIGIT SPAN RUNNING SPAN SERIESTasks created with Qualtrics and QRTE – Word association –Ī series of spoken words are presented, and for each word, the participant’s task is to type in an associated word. ![]()
