Media - computer games Flashcards
What are the 3 types of study used to investigate the effects of computer games?
Experimental
Correlational
Longitudinal
Who did an experimental study?
Bartholow and Anderson
What was the procedure for Bartholow and Anderson’s experimental study?
- Students either played a violent or nonviolent computer game for 10 minutes.
- They then all carried out the Taylor Competitive Reaction Time Task (a standard lab measure of aggression, in which students delivered blasts of white noise at chosen volumes to punish nonexistent opponents).
What were the findings for Bartholow and Anderson’s experimental study?
Those who played the violent video game selected significantly higher noise levels compared with the nonviolent players.
What is a positive of the experimental study?
Allowed us to establish cause and effect.
What are the 2 negatives of the experimental study?
Situation = artificial and unrealistic (although eases ethical issues).
Unrealistic as experiments don’t involve any fear of retaliation.
Who did a correlational study?
DeLisi
What was the procedure of DeLisi’s correlational study?
- Studied 227 juvenile offenders, all with histories of serious aggressive behaviour (e.g. hitting parents or teachers).
- Using a structured interview, they gathered data on several measures of aggression and violent computer game playing.
What were the findings of DeLisi’s correlational study?
- They found that the offenders aggressive behaviour was significantly correlated with how often they played violent computer games and how much they enjoyed them.
State the negatives of the correlational study.
- Inability to draw cause and effect - no variables are manipulated, no random allocation of participants to violent and nonviolent media conditions.
- Confounding variables.
- People who are already aggressive tend to select aggressive media (selective hypothesis).
Who conducted a longitudinal study?
Robertson
What was the procedure of Robertson’s longitudinal study?
- Studied 1037 people born in New Zealand in 1972-3 and measured their TV viewing hours at regular intervals up to the age of 26.
What were the findings of Robertson’s longitudinal study?
- They found that time spent watching TV was a reliable predictor aggressive behaviour in adulthood, measured in terms of convictions for aggressive and violent crimes.
- Those who watched the most TV were also more likely to be diagnosed with anti-social personality disorder and to have aggressive personality traits.
State a positive of the longitudinal study.
Views people as active consumers rather than as passive recipients so more realistic.
State a negative of the longitudinal study.
Confounding variables (eg models).
