The Effects of Two or More Environmental Stressors on Aggressive Behaviour An environmental stressor is a situation, which causes a negative emotional experience, accompanied by predictable physiological, biochemical and behavioural changes that are designed to help us adapt to the stressor. The three main environmental stressors are heat, noise and crowding, all of which may result in heightened physiological and psychological behaviour. A large number of studies have investigated the possibility of a connection between temperature and aggressive behaviour. Carlsmith and Anderson (1979) found that hotter weather gives a higher chance of a riot when they looked at disturbances in 79 US cities†¦show more content†¦It could also be a biological explanation. For example, the production of testosterone increases when you get hot (Anderson and Anderson, 1998). The relationship between temperature and aggression is not as simple as either the linear model or the curvilinear model, as other variables may affect the relationship. Crowding, another environmental stressor, is the unpleasant sensation that too many people share the same space. It is personal in how much it affects us, as it depends on how comfortable we feel in the close presence of others, and also how peoples perception of crowding leads to them reacting to certain levels of density. Calhan (1962) conducted an animal experiment into crowding leading to aggression. He placed an expanding rat population into a small area, and observed that they soon began sexually assaulting and killing each other, which confirms a link between crowding and aggression. Research into crowding in Australian clubs done by Macintyre and Hamel (1997) showed that the level of crowding in each nightclub was related to the number of observed aggressive incidents. This is a field experiment, meaning it has ecological validity and is not artificial and so can be applied to real life. However, they did not get participant consent for observations, which raise ethical is sues. It seems clear that crowding is related toShow MoreRelatedResearch into Environmental Stressors on Aggressive Behaviour887 Words   |  4 PagesResearch into Environmental Stressors on Aggressive Behaviour The two environmental stressors I have chosen to discuss are temperature and over-crowding. A theory that best describes environmental stressors on aggressive behaviour is the negative affect escape (NAE) theory; this claims that when the unpleasant stimuli increases so does the negative affect (the mood) and this leads to an increase of aggressive behaviour or an increase in the escape behaviour, if a personRead MoreThe Behavioral Theory Of Psychology1614 Words   |  7 Pagesdetermine a way to explore and understand human and non- human behaviour through laboratory experiments.

As they grow older, they undergo many changes in their life, and it is of no surprise that they need to learn to cope from the situation based on those changes.

More recently, research has identified that these children may need support in their own right, yet little published research is reported to inform this support. The aim of this systematic review was to identify the extent to which siblings of children with autism spectrum disorder facing
