• Testosterone is the male sex hormone responsible for the development of male reproductive organs, the production of sperm and secondary sexual characteristics like facial hair
• Males testosterone is mainly produced in the testes although a small amount is also produced in the adrenal glands, females also produce testosterone in the ovaries and adrenal glands, however in much lower levels.
• Testosterone in thought to be involved in producing aggressive behaviour. The theory states that when testosterone is high aggression increases. Lower levels of the hormone cortisol can also produce higher levels of aggression due to higher levels of cortisol blocking the aggressive influence of testosterone, therefore with lower levels of cortisol aggressive influence of testosterone would not be blocked leading to increase of aggressive behaviour.
• A02 Marcus, a 14 year old boy, was experiencing getting into trouble due to his increased fighting activity and lashing out in class as Marcus was going through puberty he would’ve been experiencing a surge in the hormone testosterone which is associated with aggressive behaviour which explains why Marcus has recently started getting into trouble
• Puberty can effect aggressive behaviour due to the increased levels of testosterone in teenage males and evidence of this activity seen in real life situations is a strength of hormones contributing to aggressive behaviour.
• The biological approach can explain aggression due to the influence of brain structure. The orbital frontal cortex is a region in the prefrontal cortex located above the eye socket. It plays important roles in cognitive functions such as rational thinking, impulsivity, self control and inhibition of aggressive behaviours. If damaged behaviour is therefore not regulated and there is an inability to inhibit appropriate social behaviour. Less activity in the prefrontal cortex due to physical damage or individual differences would explain irritability, impulsivity and difficulty controlling anger
•  A Watson who hit their forehead in a bicycle accident damaging their prefrontal cortex began to show increased aggressively reactive behaviour and started getting into physical fights, Watsons change in behaviour would be explained by his less active prefrontal cortex due to the incident and this example would explain the brain structure playing a role in aggressive behaviour.
• Aggressive behaviour can also be explained by Sigmund Freuds non biological theory of our unconscious instincts our death instinct Freud called Thanatos and our life instinct Eros. Over time our instinct builds up creating a pressure we cannot control and makes us to something aggressive, our Thanatos drives us to self destruct however our Eros protects us from ourselves by redirecting this aggression towards others.
• Beth is frustrated by the difficulty of her coursework her Thanatos urges her to rip up the paper however her Eros protects her from failing her coursework and instead Beth redirects her aggression verbally at her brother who left her door open. This example of our unconscious instincts explains how aggression can be explained by the psychodynamic approach due understanding that Beth’s aggressive behaviour towards her brother was her redirecting her anger protecting herself from the self destructive behaviour of wrecking her work inevitably causing her to fail.
