The current script incorporates features from the following studies: Bushman, B. J. (1995). Moderating role of trait aggressiveness in the effects of violent media on aggression. Journal of Personality and Social Psychology, 69, 950-960. Anderson, C.A. & Dill, K.E. (2000). Video Games and Aggressive Thoughts, Feelings, and Behavior in the Laboratory and in Life. Journal of Personality and Social Psychology, 78, 772-790. Denson, T.F., von Hippel, W., Richard I. Kemp, R.I. & Teo, L.S. (2010). Glucose consumption decreases impulsive aggression in response to provocation in aggressive individuals. Journal of Experimental Social Psychology, 46, 1023–1028. ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Participants are told that they play a game with a second player (in reality the co-player is the computer). The goal is to be faster to press the mouse button if a target square turns from yellow to red. The 'loser' has to endure a blast of white noise. Before the participant gets to play, she is asked to select the duration of the blast to be delivered (0s-2s). The intensity of the blast is kept constant in this script. The game consists of 25 rounds. Script: CompetitiveReactionTimeTask.iqjs offers the possibility to set both intensity and duration Script: CompetitiveReactionTimeTask_Intensity offers the possibility to set intesity of blast with a constant duration ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 10 minutes to complete ___________________________________________________________________________________________________________________ DATA OUTPUT DICTIONARY ___________________________________________________________________________________________________________________ The fields in the data files are: (1) Raw data file: 'competitivereactiontimetask_duration_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. trialCount: custom trialCounter feeBackIntensity: sets the constant intensity of the blast on a scale from 0-10 (default: 5) volume: records the volume with which the blast has to be delivered win: 0 = participant wins; 1 = participant loses outcomeDuration: stores current duration of outcome trial (depends on feedback or blastduration) blastDuration: stores the current duration selected by participant in levels (1-10) blastDurationMS: stores the current selected duration in ms feedbackDuration: stores the current feedback duration (duration chosen by 'co-player') rtDuration: stores the current latency (in ms) for selecting duration rtReady: stores latency (in ms) to select ready button rtTarget: stores latency to (in ms) of target response when target turns red (2) Summary data file: 'competitivereactiontimetask_duration_summary*.iqdat' (a separate file for each participant) This script computes blastintensity and duration separately (as well as overall) for - stage 0 (first trial; Denson et al (2010) used first trial aggression as main DV) - stage 1 (trial 2-9) - stage 2 (trial 10-17) - stage 3 (trial 18-25) 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) feeBackIntensity: sets the constant intensity of the blast on a scale from 0-10 (default: 5) firstDuration: stores the duration selected for the first roundtrial maxWinLatency: maximum latency (in ms) that allows player to win the current game; any reaction times above => lose (even if it was a predetermined 'win' trial) default: 700ms meanBlastDuration: mean blastduration in ms (includes all 25 trials) meanBlastDuration1: mean blastduration in ms of stage 1 (trial 2 - trial 9) meanBlastDuration2: mean blastduration in ms of stage 2 (trial 10 - trial 17) meanBlastDuration3: mean blastduration in ms of stage 3 (trial 18 - trial 25) meanrtDuration: mean latency (in ms) of setting duration (includes all 25 trials) meanrtReady: mean latency (in ms) of selecting Ready button (all trials) meanrtTarget: mean latency (in ms) of target response when target turns red (all trials) ___________________________________________________________________________________________________________________ EXPERIMENTAL SET-UP ___________________________________________________________________________________________________________________ * 25 rounds/trials, stage 0 = trial 1; stage 1 = trial 2 - trial 9; stage 2 = trial 10 - 17; stage 3 = trial 18 - trial 25 * by default different editable values and lists govern the duration/intensity the computer chooses for those different stages; -> change values under EDITABLE CODE -> Editable Values -> change lists under EDITABLE CODE -> Editable Lists (A) TRIAL SET-UP 25 trials = 25 trial sequences; each trial sequence consists of 9 steps 1. trial.start presents the UI of the game; lasts for a random amount of time (EDITABLE CODE -> Editable Lists) 2. trial.duration let's participants set the duration of the blast 3. trial.ready let's participants select the ready-button 4. trial.target_wait target sits there being green for a random amount of time (EDITABLE CODE -> Editable Lists), presumably because participant have to be both ready before the yellow square should be presented. 'Ready' button turns purple. 5. trial.target_yellow target box turns yellow for a random amount of time (EDITABE CODE -> Editable Lists) = warning signal 6. trial.target_red target box turns red; waits for participant's mouse click/touch; waits a random amount of time to reveal the outcome (EDITABLE CODE -> Editable Lists) to pretend the computer has to wait for 2 responses 7. trial.outcome reveals who won, delivers the blast (if participant lost), lasts as long as set blastduration or duration set by computer; reveals the setting the co-players have chosen under certain circumstances 8. trial.end continues to show the setting the co-player chose until the settings have been displayed for a set amount of time (EDITABLE CODE -> Editable Values) (B) DURATION SETTINGS 1) Duration is set by selecting a level 0-10 of a Duration Meter. The levels are each displayed with a specific duration in s. Once the duration is selected, the meter turns gray including the selected level. exception: if duration = 0 is selected, the 0 level turns yellow instead of gray to highlight the non-aggressive choice. 2) Duration is selected last. Once selected, no changes can be made 3) The specific durations used for each level can be set under EDITABLE VALUES -> Editable Values ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ Instructions are provided by Millisecond Software.
