MEDIA INF ON AGG : EFFECTS OF COMPUTER GAMES Flashcards
what 3 methods do media psychologists use to study?
experimental
correlational
longitudinal
what are experimental studies?
lab based
look at the short-term effects of cg on agg
what are correlational studies?
look for an association between two variables and can look at the short-term effects on computer games on agg
what are longitudinal studies?
investigate behaviour for prolonged period of time, look for long term effects of computer games on agg
what methods brings together the 3 methods that media psychologists use?
meta-analysis giving overall judgement of the size of the effect of violent media on agg behaviour
who conducted experimental studies?
Bartholow and Anderson
what were the two conditions of Bartholow and Anderson’s experiment?
violent computer game (Mortal Kombat) and a non-violent game (PGA tournament golf)
what did everyone carry out after playing a vio-non-vio game in Bartholow and Anderson’s experiemnt?
Taylor Competitive Reaction Time Task
what is Taylor’s Comptetitive Reaction Time Task?
a standard lab measure of agg where student delivered white noise at chosen volumes to punish the non-exist opponent
what were the findings of Bartholow and Anderson’s experiment?
those who played a violent game selected significantly higher noise levels comp to non-vio players
what were the mean noise for the vio/non-vio players in Bartholow and Anderson’s exp?
vio - 5.97 decibels
non-vio - 4.6 decibels
what conducted correlational studies for media inf of agg?
DeLisi et al
who did DeLisi et al study?
227 juvenile offenders with histories of serious agg behaviours
how did DeLisi et al gather info on ppts?
structured interviews
what data did DeLisi et al gather from structured interviews?
several measures of agg and vio computer game playing
what were the findings of DeLisi et al’s study?
offenders’ agg behaviour significantly correlated w/ how often they played vio comp games and enjoyment
what did DeLisi et al conclude through their correlational study?
link is so well established that agg should be considered public health issue and that computer game vio is significant risk factor
who conducted a longitudinal study into media inf on agg?
Robertson et al
what did Roberson et al want to study?
the link between ‘excessive’ TV viewing in childhood and agg behaviour in adulthood
who did Robertson et al study?
1037 people born in New Zealand measured TV viewing hours at regular intervals up to the age of 26
what did Robertson et al find?
TV hours reliable predictor of agg behaviour in terms of convictions for agg/vio crim
what are people who watched most TV more likely to be diagnosed with according to Robertson et al?
anti-social personality disorder and have agg personality traits
who conducted a meta-analysis of previous 3 types of methodology?
Anderson et al
what did Anderson et al find?
exposure to vio comp games associated with increase in agg behaviours, thoughts and feelings
