Each letter in the acronym UNRAVEL stands for one of seven distinct categorization tasks that need to be performed in repeated sequences without external reminders of the target task at any one point - even after distractor tasks. Each of the tasks has designated response keys. The use of a particular response key is thus indicative of of the task being performed. This task requires the use of a keyboard. If the script cannot find a keyboard, an alert is given and the script is automatically terminated. Reference: Altmann, E. M., Trafton, J. G., & Hambrick, D. Z. (2014). Momentary interruptions can derail the train of thought. Journal of Experimental Psychology: General, 143, 215–226 Millisecond Software thanks Dr. Eric Altman for his collaboration on this script! ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ On each trial participants see a character inside a box and another character outside of it (above or below the box). The characters are presented in opposite corners (e.g. if one is presented on the left side of the box, the other is presented on the right side of the box). One of the characters is a letter (default letters used: A, B, V, U) and the other a digit (default digits: 1, 2, 8, 9). One of the characters is colorful (red or yellow), the other is white. One of the characters is formatted (underlined or italicized) and the other one isn't. Participants are asked to work through seven 2FC tasks in sequence without prompts telling them which task to perfrom on any given trial other than the acronym 'UNRAVEL' as a sequence guide: 1. U: is the formatted character underlined (press U) or italicized (press I) 2. N: is the letter near (press N) or far (press F) the start of the alphabet 3. R: is the colorful character red (press R) or yellow (press Y)? 4. A: is the character outside the box above it (press A) or below it (press B)? 5. V: is the letter a vowel (press V) or a consonant (press C)? 6. E: is the digit even (press E) or odd (press O) 7. L: is the digit less than 5 (press L) or more than 5 (press M)? Because each task uses unique response keys, the choice of response key on any given trial indicates the type of task (and its place in the UNRAVEL sequence) performed. On average, every 6 trials a distractor task (interruption) is presented: twice participants are asked to enter a displayed code into a textbox. Only if the code is entered correctly, is the participant returned to the current place in the UNRAVEL trial sequence. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 30 minutes to complete ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'unravel_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.

Demo Tutorial: Participants learn about the meaning of the acronym UNRAVEL while working through each task in sequence. During the tutorial, participants are told the correct responses to the task at hand (and only those responses advance the tutorial). 2. Practice: 16 practice trials with 2 semi-randomly placed interruptions (by default, interruptions occur randomly after 3, 6, or 7 trials) In this script, the average number of trials before an interruption = 5.3333 (see list.uninterruptedPracticeTrials under section Editable Lists for more detail) During practice, errorfeedback in the form of a white flash is provided for incorrect responses and participants have to correct the incorrect response before advancing. 3. Test: 4 blocks with 66 test trials per block - there is no errorfeedback during the test trials - each block starts with the U task but participants are never reminded of their place in the UNRAVEL sequence (they can, however, view the rules during each trial by pressing the Tab-key) - Accuracy is based on: a) Did the participant stay in sequence (being in sequence is based on the last performed task)? AND b) was the selected response key correct given the current stimuli (irrespective of sequence standing)? - at the end of each block: performance feedback and -if appropriate- reminder to a) be faster or b) be more accurate - 10 randomly placed interruptions per block. The average number of trials before an interruption = 6 Note: in this script, the sampling process to sample the number of unravel trials before an interruptions samples from 11 possible values without replacement (see list.uninterruptedTrials under section Editable Lists for more detail) - interruption task: 2 code trials - each trial presents a 14 letter code that needs to be entered correctly into a textbox if the code was entered incorrectly, the trial gets repeated (the code stays the same) before it moves on See list.lengthInterruptCode and list.interruptCode for more detail and to change the length/nature of the code. Example code: 'icvafuobermyln' UNRAVEL trial sequence: overview: (START) unravel trials -> interruption 1 -> unravel trials -> interruption 2->..........->unravel trials-> interruption 10 -> unravel trials (END) in more detail: unravel prep (prepares the stims) -> unravel test trial (presents the stims and waits for response) -> {optional if Tab is pressed: -> help: rules are presented until the finger is lifted off the tab key -> return to unravel test trial (presents the stims and waits for response) ->} -> randomly, on average after every 6 unravel trials: interruption -> {if incorrect code is entered: another interruption trial until the correct code is entered} -> -> unravel test trial -> etc. until end is reached ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ 1. Unravel trials: each trial - randomly (with replacement) samples whether the trial is a U or an I trial - randomly (with replacement) samples whether the trial is a N or a F trial - randomly (with replacement) samples whether the trial is a R or a Y trial - randomly (with replacement) samples whether the trial is a A or a B trial - randomly (with replacement) samples whether the trial is a V or a C trial - randomly (with replacement) samples whether the trial is a E or a O trial - randomly (with replacement) samples whether the trial is a L or a M trial letter selection: based on the selected value for the N-task AND the selected value for the V-task, a specific letter is selected (Example: the letter needs to be at the start of the alphabet and needs to be a consonant: B is selected) digit selection: based on the selected value for the E-task AND the selected value for the L-task, a specific digit is selected (Example: the digit needs to be odd and greater than 5: 9 is selected) Letter/Digit Location: the nature of the character inside the box is selected randomly (with replacement): If the letter is selected to be inside the box, the digit is placed outside the box. If the character inside the box is randomly (with replacement) selected to be to the left of the box, the character outside the box is placed on the right. Placement of Formatted Character: it is randomly (with replacement) decided whether the formatted character is the inside or the outside character. Placement of Colored Character: it is randomly (with replacement) decided whether the colorful character is the inside or the outside character. !!!Note: ALL random selections are done independently of each other 2. Interruption Code: The code to enter is assembled based on a randomly sampled length of characters (default: always 4) and a random assortment of characters (default: letters used in UNRAVEL) -> Example code: 'lura' The length as well as the character selection can be manipulated under section Editable Lists: list.lengthInterruptCode (stores the lengths) and list.interruptCode (stores the pool of possible characters) ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ - follow the original UNRAVEL tutorial generously provided by Dr. Eric Altman - can be edited 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.
