Q

broken windows

A
  • 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)

53
Q

two theories of selective attention (+ mechanism)

A
  1. early selection: fixed bottleneck that blocks processing of secondary information that isn’t goal relevant
    affects processing in visual cortex, filters processing of sensory info, prevents perception of secondary info
  2. info initially encoded and selection occurs as function of top-down processes like memory and response that bias attn
54
Q

separated letter cues study methods (4 conditions)

A

n or N and color box (red = threat)

  1. early alt focus: N, then color; ID case
  2. late alt focus: color, then N; ID case
  3. late threat focus: N, then color; ID if threat
  4. early threat focus: color, then N; ID color
55
Q

results of separated letter cues study

A

deficient fear response was only present in the early alt focus condition, when the goal-relevant info (N) was presented first

56
Q

if the later attention processing hypothesis was correct, what would have been the results of the separated cues study?

A

reduced fear response in late alt focus, because higher order processes would have been able to take in the threat info and then ignore it for the goal of IDing the case

57
Q

what were the brain imaging results in sep letter cues study?

A

reduced amygdala activation

increased lateral PFC activity (which mediates amygdala activation in psychopaths)

58

A
  1. shown pleasant, unpleasant, and neutral pics; novel and familiar pics
  2. startle and late positive potential
61
Q

what does late positive potential measure?

A

ERP sensitive to emotional nature of info, reflects elaboration on affective content

62
Q

results of bottleneck pic study on startle (+ implications)

A
  1. startle deficit in novel pictures, not in familiar
  2. higher perceptual demands for pics meant less affective response; pp have slowed perception because of attention bottleneck
63
Q

results of bottleneck pic study on LPP (+ implications)

A
  1. same LPP for novel pics, but less emotional modulation of LPP (less difference between pleasant and unpleasant images) when images were familiar
  2. pp had more elaboration of LPP during familiar trials, but the elaboration didn’t go up as much as it did for non pp
  3. surprising, because you’d think the perceptual demand would slow emotion processing
64

  5. decision
  6. emotion
97
Q

how do the paths to disinhibited behavior differ in pp vs. externalizing?

A
  1. pp: bottleneck disrupts processing, circumvents EF because fewer conflicts & cog demands, affective info peripheral or embedded in complex info doesn’t influence behavior or decisionmaking
  2. ext: overallocation of attn to motivationally significant info (reward/punish/drug), fewer resources for EF, increased emotion response
98
Q

what are two areas that psychopaths and externalizers differ?

A
  1. EF: pp normal, ext less

2. affective reactivity: pp less, ext more

99
Q

lexical decision: women v. men (implication?)

  2. ASPD violence in women may be because of emotional hypersensitivity
100
Q

emotion modulated startle: women v men

A

pp women had less EMS when viewing unpleasant images than control, but only when the probe was soon (suggesting a conditional rather than fundamental emotion deficit); same as male

101
Q

fear potentiated startle: women v men (psychopaths)

A

female pp had greater FPS when focused on threat, but less with a demanding task (alt focus high load - match letter to one that occurred two times before). overreactive when threat focused, same as men in alt focus

externalizing men kept picking bad cards, while women didn’t

104
Q

passive avoidance M v F

A

male psychopaths do not inhibit behavior that was previously punished; women do

105
Q

modified stroop M v F

A

same results; pp filter out peripheral info better

106
Q

passive avoidance, W v B

A

white pp: don’t learn from punishment when pursuing reward

black: no difference

107
Q

lexical decision, W v B

A

white pp: less emotional facilitation

black: no diff

108
Q

fear potentiated startle, W v B

A

white pp: deficit in alt focus

black: no diff

109
Q

picture word stroop, W v B

A

black pp show less interference, but diff pattern than in white

110
Q

why might failures to replicate in black psychopaths not actually indicate that they are different?

A

insufficient samples; more variability in standard errors and effect sizes; different environments (black more likely to live in disadvantaged neighborhoods, be exposed to violence, experience maltreatment, have harsh parents)

111
Q

fearful faces, nonincarcerated

A

(pp were low BIS/high BAS)

pp less accurate in assessing fearful faces

112
Q

EMS, nonincarcerated

A

male pp showed same time delay for EMS, but female pp did not show a difference

113
Q

startle potentiation, nonincarcerated

A

high level of fearless dominance had less startle potentiated and less SCR in response to aversive images; high levels of impulsive-antisocial associated with smaller SCRs, mimicking pp autonomic dysfunction

114
Q

fear conditioning, nonincarcerated

A

high levels of fearless dominance meant less startle when goal focused (not on threat), but only in the low load alternative (incarcerated pp show reduced startle in low and high load)

115
Q

reward sensitivity, nonincarcerated

A

high impulsive-antisocial meant increased reward sensitivity in the nucleus accumbens (externalizing)

116
Q

4 differences in succesful psychopaths vs unsuccessful (or externalizing)

A
  1. increased heart rate stress reactivity (incarcerated pp have lower HR)
  2. enhanced executive functioning
  3. no neural differences in amygdala, PFC, or hippocampus volume
  4. no reduction in P300 during oddball
117
Q

passive avoidance same in nonincarcerated?

A

yes

118
Q

emotional empathy deficits same in nonincarcerated?

A

yes

119
Q

psychopaths show ___ deficits when viewing moral violation

A

vmPFC activation

120
Q

how do psychopaths respond to the trolley problem?

A

very utilitarian

121
Q

how do psychopaths respond to economic decisionmaking?

A

less likely to accept offers, and make low offers

122
Q

externalizing monetary tasks

A

higher NAcc activation during monetary tasks when anticipating incentives

123
Q

are schizophrenia and bipolar disorder associated with violence?

A

no

124
Q

what makes some schizophrenics and people with bipolar more violent?

A

comorbidity with antisocial traits and substance use disorders

125
Q

externalizing performance on Stroop tasks

A

worse performance on EF tasks

126
Q

what is the mechanism behind psychopathic cold rationality and failure to generate somatic markers?

A

amygdala fails to feed info to vmPFC

127
Q

where do externalizers show the biggest EF deficits?

A

when there are both demands on EF & focus on salient/motivational/emotional information; n back task where they had to press a button for mismatch and withhold for match. become so distracted by goal that they do not process affectively

128
Q

passive avoidance; newman findings?

A

context under which learning about punishment matters; only an issue when learning about reward and punishment, but able to learn about punishment when only focused on that
