Smoking motivation peer pressure
by M.A. Helmich (Submitted: 11/13/2012)
## WHAT IS IT?
This model has been created to show the influence of peer pressure on smoking behaviour in the context of perceived peer pressure and motivational orientation.
## HOW IT WORKS
• Each agent is either INTRINSICALLY or EXTRINSICALLY motivated, this is his MOTIVATIONAL ORIENTATION.
• Furthermore, each agent is either a SMOKER or a NON-SMOKER. This is displayed in the model by turltes shaped as a CIRCLE (for smokers) or a SQUARE (for non-smokers).
• Lastly, motivational orientation is not a binary concept, so there is a degree to which each agent is in terms of SELF-DETERMINATION. This can be seen in terms of shading. The darker the color of the agent, the closer he is to the far end of the scale. For example, a deep magenta means strong extrinsic motivation.
## HOW TO USE IT
• "Setup" clears the field and implements any changed settings according to sliders/switches.
• "Empty-Rate" allows you to make the world entirely full, entirely empty, or anything in between.
• "Percent-Smoker" allows you to determine the odds of smokers and non-smokers.
• The switch labeled 'neighbor' will make the agents determine whether they will change in relation to the eight turtles around them, or in relation to all the other agents in the world.
• The monitors simply count the number of agents on the field with the set of qualities described in the header of each monitor.
## THINGS TO NOTICE
• Intrinsically motivated agents tend to change less than extrinsically motivated agents. This is because they feel less 'control' from the environment.
•The formula used in this model derives from Nowak's model Sitsim, that can be found online in the model library.
## THINGS TO TRY
Try running the model with both the gradient on and off.
Make sure to notice the monitor that indicates how many intrinsics have changed. Try setting the percentage of extrinsics at 33% and see what happens to the number of changed extrinsics? Compare it to when the slider is at 50%.
## EXTENDING THE MODEL
Allowing the agents to move between different groups - seeing college students usually have different social groups they interact with, these might also influence their smoking behaviour differently.
