Personality Extremes Flashcards
what constitutes a personality disorder?
- an unusually extreme and problematic degree of one or more attributes of personality
- an enduring pattern of inner experience and behaviour that deviates markedly from the norms and expectations of the individual’s culture
- also involves impaired social relations - is pervasive, inflexible, and is stable over time
- has an onset in adolescence or early adulthood
- extreme high or low expression of any/all big five trait can result in a disorder
- symptoms can be viewed as maladaptive variations of traits, emotions, cognitions, motives, and self-concept
how can we define what is abnormal?
can be defined as something different from normal (statistical), or by considering social standards and norms (social), or a person having attitudes and perceptions that don’t line up with reality (psychological)
how are personality disorders ego-syntonic?
- people identify with the behaviours and experiences that result from their disorder
- see those things as normal and consistent with their ideal image
- less likely to believe they have a problem
how does culture, age, and gender affect what we consider abnormal?
- some cultures have different ideas of what is considered abnormal
- need to understand someone’s cultural background before any evaluation of personality disorder
- can’t diagnose anyone under 18 because their personality is changing and developing
- there may be underlying sex differences in how people cope which results in different number of diagnoses between men and women

what is psychopathy? how does is differ from sociopathy?
- similar to antisocial personality disorder but more severe and emphasizes subjective traits
- incapacity to feel guilt, superficial charm, and callous social attitudes
- sociopaths - less organized/more obvious in behaviour, less violent, maintain some emotions
what is the triarchic model of psychopathy?
boldness, meanness, and disinhibition
- boldness and lack of inhibition are related to brain circuits that process rewards
are psychopathy and antisocial personality disorder due to nature or nurture?
- evidence that they have a reduced fear response
- less coordinated activity between amygdala and prefrontal cortex (functional and structural differences)
- psychopathic offenders displayed less of the eye-blink effect but said they were equally distressed as non-psychopathic offenders
- heritability of APD/psychopathy traits in twin studies estimated at 69%
- or maybe psychopathy is the result of desensitization process - people with APD/psychopathy are more likely to have been abused early in life
what is the risk of confinement for people with antisocial personality disorder and/or psychopathy?
- about 50% of people with APD have arrest records
- prevalence of APD among prisoners is 50%, up to 70–100% of male prisoners
- yet only 25–28% of men in prison would be described as psychopaths
- those with psychopathy are more likely to recidivate (relapse) after their release
- right now, confinement is the only solution to psychopathy
what is the concept of successful psychopaths?
- can be defined as the absence of negative consequences, presence of positive outcomes/successes, or both
- intelligence, higher executive functioning, and charisma makes some more successful
- common for successful psychopaths to participate in white collar crimes

- stress-related paranoia & dissociative symptoms
how are ambiguous faces interpreted by people with borderline personality disorder?
- rate neutral faces as an emotion, and mild emotions as intense emotions
- classify intense emotional expressions quickly and accurately
- less accurately classified facial expression that were neutral or mildly sad
