• After studying a foreign language, you will forget much of the vocabulary after a year or two, but will retain 30 - 40% for decades

Darwin

• What does Darwin have to do with psychology?– Natural selection - how nature determines

which species survive - influencing both physical characteristics and behavior

– Influenced early psychologists like James– The evolutionary perspective (coming soon)– Do you have to believe in evolution to be a

psychologist?

William James - 1890’s

• Consciousness as a stream

Salt

Q4 - PerspectivesWhy different perspectives?

• Lots of different influences on behavior

• We need theories to organize information, explain facts, predict behavior

Perspectives

• Neuroscience• Evolutionary• Behavioral genetics• Psychodynamics• Humanist• Behavioral• Cognitive• Socio-cultural

Q7 - Behaviorists - 1910’s

• Pavlov, a physiologist, studied animals

• Watson, a PhD psychologist, saw no value in studying the “mind”

• Self-actualization: openness to experience, living in the moment, trusting oneself, a “good life”

Q9 – Watson and Crick - 1950’s

• Description of DNA

• Boom in genetics

• How do genes affect our behavior? How come one identical twin is alcoholic and one isn’t?

1960’s and later

• Q10 - Cognitive psychology - how do we think, plan, remember, judge, learn

• Q11 - Sociobiology and evolutionary perspective

• Q12 - Socio-cultural psychology - how do people around the world differ? How are they similar?

Neuroscience

• New methods of brain research allow us to watch our brain in action.

• How do we process memories?

• What’s the brain chemistry of mental illness?

• Neuroscience – What areas of the brain are active when

swimming?– What brain chemicals are important in

depression?

Big questions?

• Q6 - Nature vs. nurture?

• Change vs stability?

• Rational vs irrational?

Some conclusions

• Psychology is still growing as a science

• Do we have all the “right” answers?

• Genetics and brain science are the major driving forces today

• Plenty of big questions remain unanswered - what’s a good life? Is this love? What is a memory?
