Robert Krikorian - Personality Factors in CR
---------------------------------------------

Data collected at the first CR Conference - 18 months ago.

Questions
o     What kind of people would pursue CR?
o     What is their mood?
o     How do we stack up on inhibitory control?

Added a contrast group of dieters to contrast our data with.

Is there a reason to add another contrast group - anorexics, or standard diet.

Mood states -   Measured:
o     Tension
o     Depression
o     Anger
o     Vigor
o     Fatigue
o     Confusion
o     Total mood disturbance (-1 * vigor + sum of other five)

Neo Five Factor Inventory - measures personality traits
o     Use to assess normal personality (not psychopathology)
o     Reduces facets of one personality into five relatively independent
      dimensions
o       Neuroticism - tendency to experience with fear, embarrassment
o       Extroversion - sociable, cheerful
o       Openeness to experience - attention to inner feelings, curiousity
o       Agreeableness - altruism, sympathetic
o       Conscientiousness - determination, impulse control, planning

Stop-Signal Task
o     measures inhibitory control
o     Ask subject to make rapid response to stimulus, but then throw in
      another signal, a signal to stop responding.
o     Measures how well people can stop their response.
o     Correlates with high level behavior like impulse control, beating
      ones wife, etc.

14 CRonies from Las Vegas conference
14 Dieting people as contrast

Demographics:
o     Age - CRonies 45.6 vs. dieters 34.5
o     Education - similar
o     Gender - matched
o     IQ Estimate - CR 125, Dieters 109
o     Weight - 137 vs. 188
o     BMI - 19.3 vs. 27
o     Calories - 1857
o     Time on CR - 57 months

On average, CRonies have higher IQ than 97-98% of general population

Mood Data:
o     "reassuringly uninteresting"
o     Trend for CRonies to be a little more tense than dieters - but
      otherwise nothing going on.
o     CRonies not much different from general population in mood either.

Personality:
o     Neuroticism - not much different from dieters
o     Extraversion - CRonies less extraversion than dieters
o     Agreeableness - CRonies lower than dieters - more self-centered,
      less altruistic

Personality - CR compared with general population
o     Neuroticism - CR higher
o     Extraversion - CR higher
o     Openness - CR higher
o     Agreeableness - CR Higher
o     Conscientiousness - CR Higher

Stop Signal Task in CR vs. Dieters
o     Reaction time when we made the right choice slower in CRs
o     Reaction time when we made a mistake slower in CRs
o     CRonies are doing well on task (making the right answer)
o     We may be more cautious - more deliberative
o     We are equally accurate, but slower

Paul McGlothin says he thinks its glucose. When he needs to react and think
quickly, and have good recall, Paul boosts glucose and does better. 
There is evidence to support this.

Conclusions:
o     CR society types tend to be very intelligent
o     No evidence of mood disturbances
o     CR subjects are very much open to new experiences compared w/ general
      population, but not compared with sample of dieters
o     CRonies may be more caution in decision making
