Intro to Individual Differences
         Intro/Overview
         In-Class Ice Breaker
• Sit next to your classmates and find out
  similarities/differences you have with
  him/her:
  – Basic info (name, major, etc.)
  – Obvious physical attributes
  – Not-so-obvious psychological attributes:
     • Along personality dimensions
     • Interests, attitudes, values, political viewpoints, etc.
     What about Psychological
           Variables?
Intelligence?
Personality?
Proneness to Mental Illnesses?
Social Attitudes?
Interests?
Religiosity?
    From Experimental Psych to
        Differential Psych

• Experimental psychology:
  – examines psychological processes assumed
    to apply to everyone
• Differential psychology:
  – examines the ways people differ
         Behavior Genetics
The area of psychology concerned with the
 application of genetic methods and
 research designs to study the nature and
 origins of individual differences in humans
 and animal behavior.
              Why Care?
             2 recent events:

• Human Genome Project

• Case of Bill and Kathy
Human Genome Project (HGP)
• Began 1990
• Sponsored by U.S. Department of Energy
  (DOE) and National Institutes of Health
  (NIH)
• $3 billion dollar endeavor
• Goal: identify the approximately 30-80
  thousand genes in various organisms’
  DNA, including humans
Human Genome Project (HGP)
• Craig Venter of Celera Genomics
        Other Notable Progress
• Complete sequences of the genomes for the
  following have been published:
  –   Nematode
  –   Fruit fly
  –   Mustard plant
  –   Mouse
  –   Rat
  –   Chimp

       • What’s the point of sequencing/mapping the genetic info for
         these animals and plants?
      What does this mean?
• “Arguably the most significant scientific
  discovery of the new century”
• Medical applications (inherited diseases,
  common diseases—e.g., cancer)
• Academic implications

                     Matt Ridley, Genome (1999)
    Issues: Ethical, Moral, Legal
            Implications
• Human genome data is providing rapid
  info on various disorders for inherited
  predispositions
• Scientists may soon be able to make
  predictions about the future health of
  individuals (e.g., probability that someone
  may develop a particular cancer, or even
  schizophrenia)
    Issues: Ethical, Moral, Legal
            Implications
• The myriad of hypothetical problems raised by
  such info is really boiled down to one word:
  Access
• Question: Who should have access to this
  info, given that most of the research on the
  human genome is publicly funded? Should
  the public therefore have unlimited access to
  this info? What about health/life insurance
  companies? Or your potential employer?
     What about Psychology?
-Genetics central to psychology:

  Bio Sciences---Genetics---Beh. Sciences

-Other areas: psychiatric genetics,
  psychopharmacogenetics, cognitive
  neuroscience, evolutionary theory, health,
  and aging psychology

Is Human Cloning morally or ethically wrong, and should it
   be banned in the U.S.?
  Case of Bill and Kathy
Projected completion of cloning procedure:
                   2003
          Panos Zavos, Ph.D.
Kentucky-based embryologist/Reproductive Specialist
Human Cloning
Extending the Case Further…
• 200 couples volunteer to participate in cloning attempts
   – Backed by massive private funding and organizations such as
     the U.S. National Academies’ Committee on Science,
     Engineering Public Policy, and the Board of Life Sciences


• Zavos: “cloning will help us put an end to so many
  diseases, give infertile men (and women) the chance to
  have children…”

• Caplan: “if you look at the carnage associated with
  animal cloning there is probably a ratio of about 290
  dead embryos for every one that goes anywhere”
   How will this child develop?


• IQ
• Aspects of personality
• Potential development of psychopathology
