Developmental Psychology

After taking a general look at psychology and some of its major theories, we will trace psychological thought about the human life by focusing on human development. We will look at models of human development put forward by Saint Thomas Aquinas and other Catholic philosophers, Jean Piaget, Sigmund Freud, Erik Erikson, and Lawrence Kohlberg, as well as a few others. Students will not only learn about psychology, they will also learn a lot about themselves.

Christian Anthropology & Behaviorism

Christian Anthropology
Humans Are . . .
  • Spirit and body.

  • Free will.

  • Made to seek what is true and good.

  • Made in the image of God.
Sense Knowledge = Ability to know the physical world through our senses.
Sense Appetites = Ability to recognize and desire what is good for the organism’s physical bodies.
Will - Spiritual Appetite = Ability to recognize and choose what is good for the organism’s spiritual nature.
Intellect - Spiritual Knowledge = Ability to know the truth about spiritual things


Behaviorism: Classical Conditioning
Charles Darwin - Theory of evolution led to new ways of thinking about man and animals.

Ivan Pavlov

  • Physiologist (studied physical systems of the body).

  • Studying digestive system of dogs.

  • Discovered that dogs would salivate at the sound of footsteps as much as they did in the presence of food.

  • Taught dogs to salivate at the sound of a bell by ringing a bell every time they were in the presence of food. After some time, dogs would salivate at the sound of the bell without the presence of food.

  • Stimulus = something that causes a response in an organism

  • Response = the reaction to the stimulus

  • In nature, there are stimuli that naturally cause a predictable response in an organism.

  • Natural Stimulus = something that causes a response in an organism without the need to learn to respond to it

  • Natural Response = an unlearned reaction to a stimulus

  • Unnatural Stimulus = something that causes a response in an organism only after the response is learned

  • Natural Response = a learned reaction to a stimulus that would not normally produce a reaction

  • When an unnatural stimulus is associated with a natural stimulus, it can create the same response under artificial circumstances.

Behaviorism: Operant Conditioning
John B. Watson
  • Used Pavlov’s findings to determine behavior.

  • Boasted that behavior therapy was strong enough to make anyone anything you wanted.

  • Baby Albert experiment.
Operant Conditioning
  • Unconditioned stimulus & unconditioned response = naturally occurring stimulus-response relationship

  • Conditioned stimulus & conditioned response = learned stimulus-response relationship

  • Conditioning = the process of learning the relationship between an unconditioned stimulus and an unconditioned response

  • Reinforcement = reward or punishment

  • A conditioned stimulus – response relationship can be created out of nothing (i.e. no unconditioned stimulus-response nature is necessary) by pairing the relationship with positive reinforcement (reward)

  • Any stimulus-response relationship can be destroyed by pairing the relationship with negative reinforcement (punishment)
Albert Bandura
  • More faith in human ability to reason (intellect & will)

  • We choose associations we want to keep

  • Modeling = imitating those around us
