Hormones Flashcards
Hormones
Testosterone
Testosterone producing the ovaries and the testies
it stimulates the amygdala to heighten behavior such as aggression
It’s an androgen hormone means it is a male hormone
It also affects the secure development appearance and the main sex drive
Testosterone females is more linked to competitiveness and domination tham pure aggression
high testosterone = higher lvls of aggression and more exitable and ppl take more risks
Hormones
cortisol
This inhibits aggression causing hormones such as testosterone
Low cortisol lvls = high aggression lvls
high cortisol lvls= low aggression lvls
it also increases blood pressure
it’s released during moments of psychological or physical stress
produced in adrenal glands
and it’s function is to prepare the body for action
in response to stress
Hormones
Evidence + testosterone
(wanger et al 1979)
Wanger et al 1979
injected castrated mice with testosterone and their aggression levels went back to pre-crustcreation levels this is evidence supporting the link of testosterone and aggression
as it provides a link between the two
Hormones
bad research
testosterone wanger et al 1979
In Wanger et al 1979
the mice may not of had the same reaction to testosterone than that of a human due to different biology
this means that the results that testosterone effects aggression
Hormones
evidence - eisenegger et al 2009
(testosterone)
Eisenegger et al 2009
He found out that in 120 females some of whom were given testosterone some of them were given a Placebo when asked to distribute money and negotiate for more money people with the placebo made more aggressive offers
This suggests that testosterone does not cause aggression
and therefore evidence against the theory
evidence against eisengger et al 2009
[Hormones]
The sample in that study was gynocentric as all 120 ppts were female
and therefore the studys results (testosterone dosn’t cause aggression) can not be generalised to males
Hormone
Evidence +
cortisol van goosen et al 2007
van goosen et al 2007
found that cortisol inhibits aggression in the same way that testosterone increases it therefore supports the theory that cortisol inhibits aggression
bad research cortisol unethical
hormones
studying the effects of cortisol is unethical
Cortisol is produced by a reaction to stress so causing stress is unethical as it mainly blasting psychological harm which is breach of ethical guidelines
hormones comparison
freud
no falsify + less reductionist
Freud as an explanation of progression is worse and hormones due to Freud being unscientific and subjective and impossible to falsify with little to no evidence that link it to congression whereas hormones can be more scientifically and objectively tested via the use of observations such as Wanger et al 1979
This means that hormones is a much better explanation and Freud on aggression
》《》《》《《》《》》》》》》
Freud is better than hormones because it’s not reductionist this is because Freud takes aspects from biology and personality and States that’s aggression is a result of both parts of the subconscious and childhood development whereas hormones only focus on the biological aspects of aggression therefore it may be flawed as it doesn’t consider aspects of Personality to effect aggression which could be an extraneous variable in some studies and therefore affect the results and lower the studies internal validity making Freud less reductionist than hormones and therefore a better explanation of aggression
hormone
conclusion + aplication
In conclusion hormones are a well researched and accepted explanation to aggression
An application of hormones is that the knowledge of testosterone causing aggression can be applied to treat sex offenders with CPA as anti-endronic effects that quickly reduces the male sex drive
making it usefull for treating male sex offenders
hormone evaluation order
testosterone and cortisol and their effects on aggression
evidence + (wanger et al 1979 or eisenegger 2009)
bad research for ones above
(if cortisol do van goosen et al 2007 and unethical cortisol)
conclusion
aplication to CPA and male sex offenders
