Exam 1 Flashcards
broken windows
- broken window is sign of neglected community, where crime thrives
- if police fix small problems, big ones will go away (e.g. turnstile jumpers, smoking in public, graffiti)
- used in NYC, and crime appeared to have gone down (but crime was already going down; failure to consider regression to the mean)
concentrated disadvantage
social problems cluster together, e.g. welfare receipt, poverty, unemployment, incarceration rate, female headed households
exposure to violence
- youth exposed to violence are 5x more likely to experience negative life effects
- highest for poor, urban, minority youth
- increased risk for antisocial behavior, justice sys involvement, antisocial psychopathology
mechanism of transmission: directly links env and individual’s behavior
BIS/BAS
- BIS: inhib goal-dir behav when threats/novel stim detected
- BAS: mediates reaction to reward cues
- nonspecific arousal system (NAS) receives input
neurotic/stable
neuroticism: being anxious, irritable, temperamental, and moody. high in prisoners
extravert/introvert
extraversion: being outgoing, talkative, sociable, and enjoying social situations
constraint (3 aspects)
- traditionalism (conservative social environment, high moral standards)
- harm avoidance: avoids excitement and danger, prefers tedious safe activities
- control: reflective, cautious, careful, rational
five factor model (OCEAN)
- openness (curious, original, intellectual, creative)
- conscientiousness (organized, systematic, punctual, achievement-oriented)
- extraversion (outgoing, talkative, sociable)
- agreeableness (affable, tolerant, sensitive, warm, kind, trusting)
- neuroticism (anxious, irritable, temperamental, moody)
negative affect/emotionality (3)
- aggression: hurts others for advantage, will frighten and cause discomfort for others
- alienation: feeling mistreated, victimized, betrayed, and target of false rumors
- stress reaction: feels nervous, vulnerable, sensitive, prone to worry
psychopathy (4)
antisocial and impulsive behavior paired with callousness, low empathy, low IP emotions; attention problems and hypo-emotionality
25% of prison population, 1% of general population
primary/secondary psychopathy (+cause)
primary: biological cause, low anxiety
secondary: social disadvantage, neuroticism/anxiety, other psychopathologies
factor1/factor 2 (PCL-R) (8, 9)
- interpersonal-affective
(glibness, grandiosity, pathological lying, conning/manipulating, lack of guilt, shallow affect, lack of empathy, failure to accept responsibility) (rel to attn deficits) - behavioral-lifestyle/impulsive-antisocial
(need for stimulation, parasitic lifestyle, poor behav ctrl/early behav probs, lack of long term plans, impulsivity, irresponsibility, juvenile delinquency, revocation of conditional release, criminal versatility) (rel to reactivity, EF issues)
externalizing
problem behaviors directed towards external environment, e.g. physical aggression, disobeying rules, stealing, cheating, destroying property
antisocial personality disorder. how prevalent?
persistent legal, social, and moral norms violations
conduct d/o before 15, adult antisocial behav
2% of gen pop, 50% of prison pop
amygdala (2) (problem in psychopaths?)
important for 1. threat detection and 2. stimulus reinforcement learning (salience motivation detector)
- connects with OFC to encode expected outcomes in fear conditioning
- connects with vmPFC in somatic markers
- overactive PFC in pp may lead to underactivity in amygdala
nucleus accumbens (NAc) (4). who has more NAcc activity?
important for 1. cognitive processing of aversion, 2. motivation, 3. reward (e.g. incentive salience, pleasure, and positive reinforcement) and 4. reinforcement learning
impulsive-antisocial traits mean more NAc activity
prefrontal cortex
found to be important for a variety of complex behaviors, including planning, decisionmaking, moderating social behavior, and personality expression
overall ensures behavior is most efficiently directed towards satisfying needs
OFC (3)
- integrating signals
- modulating activity of other brain regions
- representing affective value or reinforcers in stimulus reinforcement learning, decision making, executive function
dlPFC (2)
- may be responsible for RM problems; attention
- essential for executive functions/on-line processing (ability to maintain and shift set, planning, response inhibition, working memory, etc)
vmPFC (4)
- processing risk & fear
- inhibiting emotional responses
- cognitive evaluation of morality/empathy
- choosing between outcomes
connects with amygdala for somatic markers
ACC
- involved in attention; reduced connectivity may be responsible for RM problems
- important for cognitive empathy
- flexible control of aversively-motivated behavior; tracks outcomes ot past choices and integrates reward info to allow for adaptive behavioral modification
- error-related negativity
what does damage to the vmPFC cause?
difficulty detecting irony, sarcasm, deception, and moral norm-violating behavior
cognitive empathy
theory of mind; understanding and representation of mental states that enables an individual to explain and predict others’ behavior (intact in pp; able to deliberately take perspective of a character in a story)
emotional empathy
response to affective displays by others e.g. facial expressions and emotionally evocative stimuli e.g. phrases, stories (lower in pp; reduced autonomic resp to stimuli ass with other’s distress)
somatic marker
created during process of education and socialization through connection of certain stimuli and affective states
guide behav by focusing attn on negative or positive outcomes of given action and serve as automated alarm signal
crucial for decision making
VIM
- activated by nonverbal communications of distress; initiates withdrawal response
- prereq for dev of three aspects of morality: moral emotions, inhib of violent action, moral/conventional distinction
endophenotype (5)
biological marker associated with illness
- associated with illness
- heritable
- state-independent
- familial co-segregation (occurs more often in externalizing family members than non-externalizing)
- reliable and specific to illness of interest (stable across situation and time)
P300; how is it tested?
- nonspecific measure; indexing stimulus evaluation and intensity of concomitant executive function processes (e.g. updating working memory, applying cognitive control to inhib dominant response, integrating info)
- ASPD lower P3 in response to rare events
- oddball test: repetitive stimuli presented, interruption of deviant stimulus
- endophenotype for externalizing
reactive vs instrumental aggression
reactive: frustrative aggression reacting to a threat in the moment (psychopaths and externalizing)
instrumental: designed to achieve goal (psychopaths)
serious mental illness (4)
- mental or behav disorder (excl developmental or SUD)
- diagnosable now or in past year
- sufficient duration to meet DSM criteria
- serious functional impairment that substantially interferes with one or more major life activities
error-related negativity
component of ERP; robust ERN after errors committed during choice tasks
decreased in impulsive, risk-tasking, cocaine dependent, internet addicts

Low Fear: 4 main types of evidence/studies
- fear conditioning (mustache faces)
- passive avoidance (response tests, reward and punishment)
- emotiona modulated startle when viewing images
- facial affect and tone recognition
setup of fear conditioning study
mustached faces or unmustached, one associated with shock
how was response different in pp in fear conditioning study (5)? the same?
pp had low skin conductance, low activity in OFC, anterior cingulate, anterior insula, and amygdala, but same heart rate elevation
mechanism of passive avoidance study
S+ requires response, S- causes you to lose if you respond; pp had higher errors of commission (bad responses to S-)
emotiona modulated startle experiment & results
psychopaths did not have normal startle response to unpleasant images when response was measured quickly, but had normal startle when the probe was presented later in viewing
ways pp brains were activated/not activated in emotion modulated startle
- too little amygdala and OFC activation
2. too much perceptual activity
facial affect and tone recognition study and results
pp have difficulty recognizing fearful faces, depending on the clarity of the emotion, and bad at fearful vocal tone
facial affect and tone recognition study and results
pp have difficulty recognizing fearful faces, depending on the clarity of the emotion, and bad at fearful vocal tone
3 inconsistencies found in evidence for low fear
- pp do anticipate fearful events based on HR
- pp have normal startle when measured later
- pp can perceive emotion on faces
3 inconsistencies found in evidence for low fear
- pp do anticipate fearful events based on HR
- pp have normal startle when measured later
- pp can perceive emotion on faces
4 studies for response modulation
- passive avoidance
- stroop and modified stroop
- flanker test
- lexical decision test
lexical decision test & results
asked if letters are a word or nonword (people usually recognize emotion words better; emotional facilitation)
pp did not ID emotion words better, but could identify whether word was emotional at same speed
what broadly observable brain abnormality do psychopaths have?
thinner cortex in multiple areas related to integrating information
emotion modulated startle experiment & results

how are ERPs related to pp? what do ERPs measure? what study showed this?
Stroop test
ERPs measure early attention processing; more negative ERP leads to more interference
pp had no relation between ERP and behavior

Stroop test
ERPs measure early attention processing; more negative ERP leads to more interference
pp had no relation between ERP and behavior
letter cues study mechanism (3 types)
green and red letters; shocks for some red letters
- threat focus: ID threat or not
- alt focus/low load: identify whether letter upper or lowercase
- alt focus/high load: press button if letter was the same as the letter 2 before
results of letter cues study
- similar fear potentiated startle in threat focus, less in others
- greater early ERP, suggests that abnormalities are in the early processing attention stage
