3 Serial Killers?

4 Psychopathy

5 Charles Manson “From the worlds of darkness I did let loose devils and demons with the power of scorpions to torment."

6 Pedro Alonzo Lopez: Monster of the Andes “I am the man of the century. No one will forget me.” “The moment of death is enthralling and exciting. Only those who actually kill know what I mean…When I am released I will feel that moment again.”

7 Aileen Wuornos: Highway Killer ” I robbed them, and I killed them cold as ice, and I know I would kill another person because I’ve hated humans for a long time."

8 John Gacy: Killer Clown “I should never have been convicted of anything more serious than running a cemetery without a license."

9 Edmund Kemper: Co-Ed Killer “One side of me says ‘I’d like to talk to her, date her’. The other side of me says, ‘I wonder how her head would look on a stick’."

10 Brief History of Psychopathy   Term derived from the Greek psych (mind) and pathos (suffering), and was once used to denote any form of mental illness.   In 1801, Phillipe Pinel, the founder of French Psychiatry, identified such individuals as behaving crazily without actually being crazy.   In 1812, Benjamin Rush, the first American psychiatrist, described them as patients with “innate preternatural moral depravity.   In 1886, philosopher Friedrich Nietzsche writes Beyond Good and Evil advocating the psychopathic personality as the individual’s legitimate right to becoming an “Ubermensch” or “Superman.”

11 Brief History of Psychopathy   In 1910, Freud proposes that the psychopathic personality emerges when the war between the Id’s instinctual drives resulting in an “instinct of destruction, of mastery, the will to power” and an “I see, I want, it’s mine” orientation to the world.   In 1915, Emil Kraepelin used the term “psychopathic personality” to describe amoral vs. immoral criminal types.   In 1941, H. Cleckley The Mask of Sanity, Psychopaths are human in every respect – but it is a lack of "soul quality" that makes them very efficient "machines."   In 1980, psychologist Robert Hare creates the diagnostic tool called the Psychopathy Checklist (PCL).

12 Relationship between Psychopathy & Antisocial PD PSYCHOPATHY ANTISOCIAL PD

13 Psychopathy in Life  Serial killers, repeat bank robbers, con artists, organized crime  What about other similar characters?  Robert Hare has proposed a more informative diagnostic category:  Psychopathy

14 Are Psychopaths just Anti-Social  Major distinction appears to be in symptomatology  “Lack of remorse,” a core symptom of psychopathy, is not required for diagnosis of APD.  In one study, 75 to 80% of convicted felons met criteria for APD, but failed to meet criteria for psychopathy.

15 Psychopathy FACTOR 1  Charming  Manipulative  Superficial  Shallow  Lack of remorse  Inconsistent FACTOR 2  Failure to conform  Impulsivity  Aggression  Deceitful/lying  Disregard for others  Irresponsibility Psychopathy encompasses both of these factors whereas Antisocial PD predominantly involves Factor 2

16 Factor 1 in everyday life  Lawyers, politicians, businessman  Aspects of psychopathy may be seen in many areas of life  These two factors are reliable Across sites Across sites Across cultures Across cultures

17 Psychopaths identified by Hare  Two clusters:  1. Emotional detachment cluster- a selfish remorseless individual with inflated self-esteem who exploits others.  2. Antisocial lifestyle cluster- marked by impulsivity & irresponsibility.

18 17 The Path to the Psychopath PDD ADHD FAS/FAE Bipolar LD etc… Oppositional Defiant Disorder Conduct Disorder Antisocial Personality Disorder Psychopathic Personality Disorder Inattention Poor social skills Learning deficits Aggression Destruction Deceitfulness Rule violation Manipulation Hostile Defiant Negative Criminal acts Impulsiveness Disregard safety Irresponsibility Lack remorse Stimulus seeking Lack goals Parasitic Predatory Violent  80% of kids with ADHD as children carry it into adolescence, and 60% of those had developed ODD or CD.  100% of antisocial personality disorder have diagnosis of CD as youth. 6-16% boys 2-9% girls 1% PDD 1-20% ADHD 1% FAS/F AE 4-6% Bipol ar 2-8% LD 2-16% 3% males 1% females 1% 40-50% of CD becomes ASPD

19 Are psychopaths born or made?  Most likely there are components of both that account for the development of full fledged psychopathy.

20 Causes of APD & Psychopathy?  Family  McCord & McCord concluded that lack of affection & severe parental rejection may be primary causes of psychopathic behavior.  Other suspected family related factors are: Inconsistencies in discipline or no discipline at all Inconsistencies in discipline or no discipline at all physical abuse physical abuse marital discord marital discord substance use. substance use.

21 Heritable components  Twin Studies:  1. Higher concordance rate for MZ twins than for DZ twins in APD.  Adoption Studies:  2. Higher rate of antisocial behavior in adopted children of biological parents with APD.

22 Father’s behavior  Fathers of psychopaths are likely to be antisocial personalities themselves!!!!!!

23 Environmental Factors  Environment seems to play an important role in APD.  It has been shown that environmental factors such as marital problems and substance abuse) are related to the development of APD.  Also high levels of conflict & negativity and low levels of parental warmth predict APD.

24 What’s likely to be going on?  Child with propensity for antisocial behavior may be difficult to deal with & produce environmental changes that result in harsh conditions (treatment) by family members.  This may fuel development of full blown antisocial behavior.

25 Are psychopaths less prone to anxiety than normal people?  Yes!!!  Lykken (1957) studied the ability of psychopaths & controls to avoid shock.  Psychopaths were poorer than controls at avoiding the shocks, suggesting they are low in anxiety compared to controls.

26 Do psychopaths fear little?   Psychopaths show a pattern of autonomic activity that suggests they “tune out” aversive stimuli.   Their hearts beat faster than normals when anticipating stress, but their skin conductance levels are lower than controls in response to aversive stimuli.   This makes them appear under aroused when they are not.

28 Environmental Trauma and the Brain The Case of Phineas Gage Gage was a railroad construction supervisor in 1848 when a tamping rod was driven through his skull by an explosion. The tamping rod severed the connections in the frontal area. Prior to the accident he was a moral, hardworking, sensitive, conscientious, intelligent, and well liked. Following the accident, his personality changed: lying and conning, violent, alcoholic, and antisocial. Phineas gage
