Hoelzle, J.B. (2015). The Interchangeability of CVLT-II and WMS-IV Verbal Paired Associates Scores: A Slightly Different Story. Archives of Clinical Neuropsychology, 30, 248–255. The script presents the list visually and accepts written input. Adjustments to z-scores as described by: Gregg, A. & Sedikides, C. (2010). Narcissistic Fragility: Rethinking Its Links to Explicit and Implicit Self-esteem, Self and Identity, 9:2, 142-161 (p.148) ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Participants are presented a list of 14 word pairs (fixed sequence), one word pair at a time, on the computer screen. Once the list has finished, the first word of each word pair is presented as a prompt together with a textbox. Participants are asked to enter the missing second word of the word pair into the box. Feedback is provided during the immediate recall trials. The list learning/recall task is repeated 3 more times before a break (default: 15min). After the break, participants work through an optional delayed recall test (no feedback provided) and a recognition task: 28 words are presented to them, one by one, and participants have to decide whether the word was part of the original list (if so, press Y) or not (if so, press N). 14 of the words are list words, the other ones are new distractor words. The test ends with an optional free recall test of the original list word pairs. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ Recall 1-4: ~10minutes Break: ~20 minutes Delayed Recall: ~3 minutes Delayed Recognition: ~2 minutes Delayed Free Recall: ~2 minutes ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'verbalpairedassociatestest_raw*.iqdat' (a separate file for each participant)* build: The specific Inquisit version used (the 'build') that was run computer.platform: the platform the script was run on (win/mac/ios/android) date, time: date and time script was run subject, group: with the current subject/groupnumber session: with the current session id blockcode, blocknum: the name and number of the current block (built-in Inquisit variable) trialcode, trialnum: the name and number of the currently recorded trial (built-in Inquisit variable) Note: trialnum is a built-in Inquisit variable; it counts all trials run; even those that do not store data to the data file such as feedback trials. Thus, trialnum may not reflect the number of main trials run per block. count_immediateRecallRounds: counts the number of immediate cued-recall trials run count_allRecallRounds: counts the number of ALL (immediate + delayed) cued-recall trials run familiarity: 1 = old word (word on list);

Currently, 14 unassociated word pairs are provided for the initial study list. An additional 14 unassociated words pairs are provided for the recognition test to serve as the unfamiliar (unstudied) word pairs. The word pairs as well as their semantic associations can easily be edited under section Editable Stimuli. ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ are provided by Millisecond Software - change under section Editable Instructions ___________________________________________________________________________________________________________________ EDITABLE CODE ___________________________________________________________________________________________________________________ check below for (relatively) easily editable parameters, stimuli, instructions etc. Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment. The parameters you can change are: /oldKey: the "old key" response key (default: "Y"); the left response key /newKey: the "new key" response key (default: "N"); the right response key /wordSize: proportional sizing of study words (default: 6% of canvas height) /stimDuration: the duration (in ms) that each word of a pair is presented (default: 1000ms) /pairISI: the time (in ms) in between pairs (default: 2000ms) /recallDelay: the delay (in ms) between last presented study list word and the recall trial (default: 0ms) /MinDelay: the minimum delay (in ms) between end of last immediate recall trial and the delayed recall/recognition task (default: 1200000ms = 20min) /runDelayedRecall: optional delayed recall task after the break true (1): delayed recall task is run (default) false (0): delayed recall task is skipped /runDelayedFreeRecall: optional delayed free recall task after the break true (1): delayed free recall task is run (default) false (0): delayed free recall task is skipped /runRecognitionTask: optional recognition task after the break true (1): recognition task is run (default) false (0): recognition task is skipped Note: if both the delayedRecall Task AND the recognition Task are skipped, the break is skipped as well
