H. M., de Vries, H., Cohen-Kettenis, P. T., & van Engeland, H. (1998). The Dominance of Behavioural Activation over Behavioural Inhibition in Conduct Disordered Boys with or without Attention Deficit Hyperactivity Disorder. Journal of Child Psychology and Psychiatry, 5, 643–651. ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Participants are asked to open doors. Opening a door is either rewarded with 1 point that is added to the total winnings or punished by 1 point being subtracted from the total winnings. The number of winning doors decreases over the course of the experiment while the number of losing doors increases. Participants can quit the experiment at any point keeping the number of points earned up to this point. A large number of doors opened is indicative of response perseveration ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the max duration of the game (opening all doors) takes about 5 minutes ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'dooropeningtask_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. nextoutcome: stores the win/loss status of the current door 1 = it's a win door 0 = it's a loss door response: the participant's response (here: scancode of the response key) 57 = spacebar press 16 = Q quit: tracks whether participant has decided to quit 0 = participant is still playing 1 = participant has quit the game latency: the response latency TotalScore: tracks the total points earned (updated in trial.doorchoice) summary variable: totalnumberdoors: saves the total number of doors that could be potentially opened during the experiment count_opendoors: tracks the number of doors openend before quit. Note: the more doors are opened the higher response perseveration (2) Summary data file: 'dooropeningtask_summary*.iqdat' (a separate file for each participant) inquisit.version: Inquisit version run computer.platform: the platform the script was run on (win/mac/ios/android) startDate: date script was run startTime: time script was started subjectid: assigned subject id number groupid: assigned group id number sessionid: assigned session id number elapsedTime: time it took to run script (in ms); measured from onset to offset of script completed: 0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run) ///parameter settings: skip_0percWin: true = block.0perc_win is skipped (default) false = block.0perc_win is run skip_100percWin: true = block.100perc_win is skipped (default) false = block.100perc_win is run ///summary variable: totalnumberdoors: saves the total number of doors that could be potentially opened during the experiment count_opendoors: tracks the number of doors openend before quit. Note: the more doors are opened the higher response perseveration ___________________________________________________________________________________________________________________ EXPERIMENTAL SET-UP ___________________________________________________________________________________________________________________ 1. Instruction Block 2. Block "100percent wins" (block.100perc_win) => optional; see editable value parameters.skip_100percWin ... 12. Block "0percent wins" (block.0perc_win) => optional, see editable value parameters.skip_0percWin Each block potentially presents 10 doors with a pre-assigned win/loss ratio (see list.100perc_win - list.0perc_win) => within those 10 trials win/losses are randomly sampled (without replacement) Matthys et al (1998) ran all 11 text blocks (max number of doors: 110) with a beginning credit of 0 points. Win and Loss amount both equaled 1 point. ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ are provided by Millisecond Software; see section Editable Stimuli ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ Instructions are not original and can be easily edited under section Editable Instructions (Matthys et al, 1998, provide instructions on p.645). ___________________________________________________________________________________________________________________ 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: /responsekey_open: response key to open doors (default: " " -> spacebar) /responsekey_quit: response key to quit (default: "Q") /feedbackduration: default presentation duration of the win/loss door feedback screen (default: 1000ms) /startcredits: the number of points that participants start with (default: 0) Note: that's the amount specified in Matthys et al (1998) /winamount: the number of points that participants get for opening a win door (default: 1) /lossamount: the number of points that participants lose for opening a loss door (default: 1) /skip_100percWin: true = block.100perc_win is skipped false = block.100perc_win is run (default) /skip_0percWin: true = block.0perc_win is skipped false = block.0perc_win is run (default) /present_feedbacksummary: true = one the final page of the experiments, the total score is displayed (default) false = one the final page of the experiments, the total score is Not displayed
