Walkthrough of code for simulation 👇

Pseudocode Part 1: Agents

1. Make team of 5 people

2. Set the majority race and minority race

3. Assign badge/no badge randomly to team

Code:

to do_make_agents
  create-turtles people [set Racei TRUE set Badge TRUE] ; intialize agents
  layout-circle sort turtles 6 ; distribute agents on the world's surface
  ask turtles [ set label who] ;associate each agent with number
  set n random 5
  ask n-of n turtles[
  set breed majors
  ]
  ask turtles with [breed != majors] [set breed minors]
  ask majors [set color white
  set shape "dot"
  set size 3]
  ask minors [set color grey
  set shape "square"
  set size 3]
end

Pseudocode Part 2: Interpersonal Teamwork Behavior

4. Each agents decides whether to encourage others

If they have a badge, then more racial similarity leads to more likelihood of encouragement

If they do not have a badge, then more racial similarity leads to to less likelihood of encouragement

Code:

  set cutoff1 random-float 100
  ifelse Badge = TRUE
      [
    ifelse (race_sim * 100) > cutoff1
    [set Encouragei 1]
    [set Encouragei 0]
    ]
      [
     ifelse (race_sim * 100) > cutoff1
    [set Encouragei 0]
    [set Encouragei 1]
    ]

5. Each agent decides whether they should perform Interpersonal Teamwork Behavior (ITWB)

If they have a badge, then more racial similarity leads to more likelihood of decision to perform ITWB

If they do not have a badge, then more racial similarity leads to to less likelihood of decision to perform ITWB

Code:

  set cutoff1 random-float 100
  ifelse Badge = TRUE
      [
    ifelse (race_sim * 100) > cutoff1
    [set Decidei 50]
    [set Decidei 0]
    ]
      [
     ifelse (race_sim * 100) > cutoff1
    [set Decidei 0]
    [set Decidei 50]
      ]

6. Each agent performs ITWB based on previous decision as well as encouragement from the group and validation from the group the prior time point

Code:

set cutoff3 random-float 150
    set encour_sum count turtles with [Encouragei = 1]
    set valid_sum count turtles with [Validatei = 1]
    ifelse (encour_sum + valid_sum * 10) + Decidei > cutoff3
    [set Influencei 1]
    [set Influencei 0]

7. Each agent decides to validate other group members performance of ITWB

If they have a badge, then more racial similarity leads to more likelihood of validation

If they do not have a badge, then more racial similarity leads to to less likelihood of validation

Code:

  set cutoff1 random-float 100
  ifelse Badge = TRUE
      [
     ifelse (race_sim * 100) > cutoff1
    [set Validatei 1]
    [set Validatei 0]
    ]
      [
   ifelse (race_sim * 100) > cutoff1
    [set Validatei 0]
    [set Validatei 1]
    ]

Pseudocode Part 3: Leadership

8. Each agent either perceives or does not perceive another agent as leader based on their ITWB performed compared to possible

For agenti, if agentk’s performed ITWB is congruent with their ILT, then they will add 1 to their leadership perception score (do this for all agents)

Code:

ask person_1[
        create-LP-from person_2
        [
         set weight 0
    ]
    create-LP-from person_3
        [
          set weight 0
    ]
    create-LP-from person_4
        [
          set weight 0
    ]
    create-LP-from person_5
        [
          set weight 0
    ]
  ]
    ]
    
ask LPS with [end1 = person_1 and end2 = person_2]; this is a tie with int 2 as the person being perceived
  [
      if([ITWB_prop] of person_2 > [ILT] of person_1)
                       [
                          set weight weight + 1
    ]
    ]

9. Calculate leadership score for each agent

Code:

to calculate_leader_score
ask turtles[
    set leadership_score mean [weight] of my-in-LPS; calculates the mean of all the perceptions of others
]
end
