Background

This script implements a SelfOtherPerformanceTask by C. Hobbs (email: C.Hobbs@bath.ac.uk). The task investigates the influence of social context on self performance estimates within the context of an online anagram solving game with multiple computer simulated players.

A similar task was used in the GW4 Undergraduate Psychology Consortium 2018/9 a joint research program of researchers at the University of Bath, University of Bristol and University of Cardiff: https://osf.io/54jfv/

Duration

20 minutes.

Description

Participants are asked to solve anagrams under cooperative and competitive conditions with various other players and predict their performance during each condition as well as rate their self-esteem after each game.

The task is divided into baseline phase (individual anagram solving task) vs. test phase (five cooperative games and give competitive games).

Procedure

(1) Intro:
- selection of affiliation (here: university), avatar image and avatar name
- random assignment of affiliation to computer players, so that there are 2 players from each institution
- random assignment of remaining avatars to computer players
- random assignment of names to computer players from a predetermined list of names (see helper script 'selfotherperformancetaskStimuli.iqjs')
( if participant selects one of the player names, a request for another name try is made)

(2) Practice
- 'individual' play (not team play)
- 3 pre-selected anagrams in random order
- no timelimit
- feedback

(3) Baseline
- 'individual' play (not team play)
- Task: solve as many anagrams as you can during a given time frame.
The anagrams are selected randomly without replacement from the available list of anagrams.
- timed (default: 1 minute; see section Editable Parameters)

- before participant's score is revealed, participant is asked to predict her score ('self rating');
after all points are revealed, participant is asked about her feelings ('self-esteem')

- Percentage Correct: percentage correctly solved anagrams based on the number of anagrams attempted
=> if percentage correct is below 25% => reported percentage correct is adjusted by randomly selecting from 25%, 26%, 27%, 28%
=> if percentage correct is above 75% => reported percentage correct is adjusted by randomly selecting from 72%, 73%, 74%, 75%
=> scores are directly translated into points from 0-100.

- computer player performance:
the assigned percantage corrects of the computer players are selected randomly from
- participant percentage correct + 24 (higher)
- participant percentage correct + 10 (higher)
- participant percentage correct - 1 (almost the same)
- participant percentage correct - 10 (lower)
- participant percentage correct - 24 (lower)
=> scores are directly translated into points from 0-100.

- ScoreBoard reveals the player's baseline points in order (from highest to lowest)

(4) Test
- Task: solve as many anagrams as you can during a given time frame (each player works on his/her own anagrams).
The anagrams are randomly (without replacement) selected from the list of available anagrams
- each game is timed (default: 1 minute; see section Editable Parameters)

- The test phase runs 10 rounds: five competitive and five cooperative rounds
- competitive round: two players play against each other.
The player with the higher score will get the points as calculated by the difference score,
the other player gets 0 points for that round
- cooperative game: two players play with each other ( they each solve their own anagrams).
At the end both players get the mean points earned for that round

- the participant plays against each of the five computer players twice: once in a competitive round
and once in a cooperative rounds
The remaining pairings (btw. computer players) for the games are predetermined, so that each computer player
plays against each other computer player once in the competitive and once in the cooperative round

- before participant's score is revealed, participant is shown her coplayer's score and asked to predict her own score ('self rating');
after all points are revealed, participant is asked about her feelings ('self-esteem')

- Percentage Correct for Participant ('score') during test: same algorithm used as after the Baseline Phase
- Percentage Correct for Computer-Players ('score') during test: same algorithm used as after the Baseline Phase

- Points are cumulative. At the end the final scoreBoard is revealed.
based on the random allocation of the points, participant's final standing is not fixed.


throughout the script, participants have to wait for the other players to finish.
These wait times are randomly selected from list.waitTime under section Editable Lists
