   Review of how anthropologists
    define humanness (so far)
• From australopithecus afarensis to homo
  habilis and homo ergaster, how have we
  seen our ancestors “becoming human”?

  – Physically

  – Behaviourally
         Thinking like a pig?
• Watch a quick excerpt from “the three little
  pigs”

  – Jot down the characteristics that make the
    pigs human-like.
          What makes us eat?
Animals            Humans
   First way psychologists define
            humanness
• Humans have complex motivations for
  their behaviour



  – Motivation = something (a need or a desire)
    that causes a person to engage in a
    behaviour

              Each individual has
              motivation
            Animal instincts
• Animals’ behaviour may be driven largely
  by instinct

  – Instinct = natural or inherited impulse


                   The lion does not say to himself, “hmm, I
                   think I will go out and kill someone today.”
                      Puzzles
• Have you ever tried to solve a puzzle?
  –   Crossword
  –   Sudoku
  –   IQ test
  –   Try the two problems on the bottom of page 50 in the
      textbook


• How did you go about trying to solve the
  problem? What process did you use? What went
  through your mind?
 Second way psychologists define
          humanness
• Humans have the ability to reason at a
  high level

  – See page 48 in text
     • Focus on cerebral cortex


  – See “Problem Solving” handout
    Third way psychologists define
             humanness
•   For homework, read “Polly Wanna
    Ph.D?” and answer these questions:
    1. What can Alex do that is special?
    2. What safeguards has Pepperberg put into
       her experiments to make sure Alex isn’t
       responding to cues or being generously
       interpreted by humans?
    3. Is intelligence needed for communication?
