The effects of environmental stressors on aggressive behaviour?

Extracts from this document...


The effects of environmental stressors on aggressive behaviour? Environmental stressors are situations which cause a negative emotional experience. A01: Temperature Temperature is a potential source of stress which leads to aggressive behaviour. Temperature may be casually linked to other external factors, which are in turn casually linked to aggressive behaviour. One such explanation is routine activity theory as proposed by Cohen and Felson (1970), which states that opportunities for interpersonal aggression increase in summer as people change their pattern of routine activity. For example they are likely to be more outdoors hence coming into more contact with other people. Increase in alcohol consumption during hot weathers may further compound this. Another example which could be given is when being stuck in a train. Imagine the journey is still long to go and the train is packed with people close together. ...read more.


They found a curvilinear relationship in that aggression increased up to about 34 degrees and then decreased. Boron theory is supported by labourtory studies but not by real life correlation ones. This is not easy to explain. Laboratory studies lack ecological validity and do not measure real life aggression. 2. Boron and Ransberger (1978) in a naturalistic correlation study found that violence was highest around 29 degrees, but it then declined as the weather got hotter. As this was a loabortory experiment, it lacks ecological validity. On the other hand the real life situations the stimuli that provoke people are more intense and therefore more likely to stimulate aggression. 3. The apparent rise in violent crime during summer months may be due to other factors other than temperature. People are out on the streets more in summer - there is greater social contact hence more opportunity for assault, rape and homicide. ...read more.


They showed violent and non-violent film clips to participant. Participants were then told that they could evaluate the work of another person in a nearby room by giving him electric shocks (these were actually fake). One group gave shocks in a noisy environment, whereas the other group did so in a normal environment. The noise background group who had watched the violent.........gave more shocks than the other conditions. (Findings) Conclusions It would seem that only the violent film/...... noise combination caused aggression, not the noise level by itself. A02 - Criticisms + 1) noise does not cause aggression directly. As studies have shown, noise can contribute to aggression, but only when the person is altered frustrated or angered. Therefore it appears to have face validity. - 2) People who believe that they can control the levels of noise do not appear to become aggressive. This occurs even when they do actually experience loud noise and do actually control it. Their belief that they can control the noise is important in rewarding aggression. ...read more.
