The original Überball script is adapted from the following Cyberball Inquisit 4 script: SCRIPT INFO: last updated 04-02-2014 by K. Borchert (katjab@millisecond.com) for Millisecond Software Millisecond software updated the user manual and added several Inquisit 6 variables to the data file as well as added a sizing parameter for the video size. ___________________________________________________________________________________________________________________ BACKGROUND INFO ___________________________________________________________________________________________________________________ Überball runs a preferential social inclusion condition which increases fundamental needs fulfillment in contrast to the exclusion game played by traditional cyberball games. Überball is based on: Simard, V., & Dandeneau, S. (2018). Revisiting the Cyberball inclusion condition: Fortifying fundamental needs by making participants the target of specific inclusion.

The number of trials can be edited under EDITABLE PARAMETERS/EXPRESSIONS. * By default, all players are represented by names. Names and pictures can be edited under EDITABLE STIMULI. To change names or pictures go to EDITABLE PARAMETERS/EXPRESSIONS. * By default, player 1 and player 4 throws the ball to participant (=player2) AND DO NOT throw to player 3. Go to EDITABLE LISTS for further instructions. * Decision Times for Player 1,3 and 4 are controlled by expressions.cyberdecisiontime under EDITABLE PARAMETERS/EXPRESSIONS. * Instructions can be edited under EDITABLE INSTRUCTIONS ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ picture examples are provided by Millisecond Software. They can easily be edited under section Editable Stimuli ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ 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. The parameters you can change are: /max_trialcount: maximum number of trials (= passes between the players) played /showpictures: true = pictures of players are onscreen false = no pictures are presented (default) /showlabels: true = labels of players are onscreen (default) false = no labels are presented NOTE: parameters.showpictures and parameters.showlabels cannot be set to false at the same time. /videoSize: sets the size of the video relative to canvas
