Week 3- Psychophysiology & Lie Detection Flashcards
what are components of NS (the mind map)
NS: CNS & PNS
PNS: autonomic NS & somatic NS
autonomic NS: sympathetic NS (fight or flight) & parasympathetic NS (rest & digest)
For HR, skin conductance & EEG, what NS are they regulated by
HR: ANS
Skin conductance: sympathetic NS
EEG: CNS
Why indvs w lower HR have greater rush of both being perpetrators & victims of crime
Put themselves in such situations
4 explanations of why HR related to ASB
- Stimulation seeking most impt
- Fearlessness
- Same set of genes encode for ASB & HR
- Low HR reflects right hemisphere dysfunction
Low resting HR more ass with proactive or reactive aggression
Proactive
How does biology & social factors interact to lead to ASB (social neurocriminology & social push)
Social neurocriminal: social adversity causes ASB through Low HR during stress
Social push: Low HR more ass with high SES than Low SES/ for good home, biology drives ASB more
Is high HR protective
YES!!
Low skin conductance, high ASB. How about substance abusers?
nOPE. Only ASB
Which brain wave associated with high ASB
theta waves!!
Why is theta waves (slow wave) associated with ASB
- Criminals have underarousal of CNS
2. This wave is shown by children, so maybe delayed cortical maturity
What is the classical conditioning theory of ASB
ASB means cannot form CS- UCS associations well fail to associate stimuli w punishment poor socialization antisocial
Fear conditioning paradigm
loud noise —> fear
soft noise —> no fear
soft then loud noise —> fear
soft noise —> fear
Does ADHD affect skin conductance orienting
NO, only ASB
Issues w polygraph
- subjects can train to manipulate it
- examiners may be untrained
- actual reason might be fear rather than lying
Those who lie a lot have lower or higher prefrontal cortex volume
Higher
