forensics- psychological explanations of offending behaviour Flashcards
what is eysencks criminal personality (definition)
an individual who scores highly on measures of extraversion, neuroticism, psychoticism and cannot be easily conditioned, is cold and unfeeling, likely to engage in offending behaviour
what were the 2 dimensions eysencks and then what was the 3rd and his theory is …..
introversion - extraversion
neuroticism - stability
psychoticism - socialibility
BIOLOGICAL (determinism)
our personality traits all have a biological basis > come through in the type of nervous system we inherit
so must mean that all criminal personality types have a bio basis
how do extroverts link to criminal personality biologically, what are they.
they have an underactive nervous system SO constantly seek excitement, stimulation, they WANT THRILL so more likely to engage in risk taking behaviours
how do neuroticism link to criminal personality biologically, what are they.
high level of reactivity in sns so individuals respond quickly to situations of threat (f/f r)
so they do things without thinking because they are overanxious, they could potentially enter a dangerous situation
nervousness, jumpiness and overanxious and this form of instability makes their behaviour difficult to predict
how do psychoticism link to criminal personality biologically, what are they.
high levels of testosterone and which leads to increased aggression and unemotional, lack of morals and remorse and empathy
how can we measure criminal personality and describe and why is this useful
eysencks personality questionnaire
this is a psych test which locates respondents along the three dimensions (introversion - extraversion neuroticism - stability psychoticism - socialibility) to establish their personality type
based on this Q E could conduct research relating personality behaviours to other behaviours eg criminality.
what is the role of socialisation in cp for eyseck
thought that p is linked to offending b via socialisation processes ie if you have these p characteristics (P, E, N) then you cant learn to delay gratification/difficult to condition as a child, because of the nervous system that you have inherited and so offending b occurs as less likely to learn anxiety responses to antisocial responses therefore more likely to act antisocially
offending b is concerned with selfishness and immediate gratification, children and taught to delay gratification via socialisation.
