Title: How do you think modern technology affects learning?
1 - How do you think modern technology affects
learning?
2- Learning-a relatively permanent change in
behavior due to experience. - Associative Learning-learning certain events can
occur together - Conditioning
- Classical Conditioning-learn that one stimuli
predicts another, for example that a bell
predicts class change. Sometimes we flinch, as
if to get up, at the lunch bell. - Operant Conditioning-behavior is influenced by
its consequences. Example-studying gets you
good grades.
3Classical Conditioning-Pavlov
- Pavlov did an experiment with dogs, discovering
that by associating a tone with food, he could
eventually condition dogs to salivate to a tone
alone. - http//www.youtube.com/watch?vhhqumfpxuzI
4- Experiment
- Neutral Stimulus (bell)-no response
- Unconditioned stimulus (food)
- Unconditioned response (drool)- natural response
- Conditioned stimulus (bell)- formerly neutral
- Conditioned response (drool) in response to CS

5- Acquisition-pairing NS and UCS (getting
classically conditioned) - Extinction-CS no longer elicits the CR when the
CS no longer signals the uncond. stimulus - Spontaneous recovery-return of CR that has been
extinct for no apparent reason - Generalization-respond to anything similar to the
CS - Ex. Fearing all dogs if a pit bull bites you
6- Discrimination-ONLY respond to CS and nothing
similar - Ex. Only fearing Pit Bulls because one bit you
7Little Albert Experiment
- John B. Watson wanted to condition a baby to fear
a white rat and then see if that fear was
generalized to other fluffy white objects. - http//www.youtube.com/watch?vXt0ucxOrPQE
8Operant Conditioning vs. Classical Conditioning
Classical Conditioning Operant Conditioning
uncontrollable biological based response Ex-flinch, blink, sweat, drool. Stimulus, then learned reaction based on stimulus (human action comes second) Controllable action Ex. Study to get good grades Learned reaction, then consequence Based on consequences (human action comes first)
9Thorndike and the Law of Effect
- Behavior is influenced by its consequences

10Skinner Experiment
- Skinner experimented with different schedules of
reinforcements with animals. - Skinner Box- box animal placed in, usually with a
bar or lever to push, resulting in reinforcement
for an animal - http//www.youtube.com/watch?vI_ctJqjlrHA
11- Shaping-reward for closer and closer
approximations to a desired behavior - http//www.youtube.com/watch?vcAtDw87bhcw
12- Principles of Reinforcement
- Primary reinforcer-naturally rewarding
13- Secondary reinforcer-it is rewarding because it
can help one get a primary reinforcer
14Both Positive AND Negative Reinforcement always
increases behavior
- Positive reinforcement-increase behavior to get a
reward - Ex. Do chores to get an allowance
- Ex. Giving candy to a child throwing a tantrum in
Walmart
15- Negative Reinforcement-increasing a behavior to
STOP or AVOID something bad - Ex. Clean room to AVOID lecture
- Ex. Click seatbelt to AVOID annoying dinging
sound - Punishment-decreases behavior that it follows
16Schedules of Reinforcement
Schedule Description Resulting Behavior
Continuous Reinforce every time Quickest to become extinct when the reinforcement stops
Fixed Ratio Reward after a specific number of tries Frantic response that could exhaust the organism
Variable Ratio Reward after random number of tries (Gambling) Hardest behavior to extinguish even after the reinforcement stops
Fixed interval Reward after a specific time period Behavior increases only when it is close to reward time
Variable interval Reward after a random amount of time Behavior is slower, but steady
17skinner box and video gamesPunishment
- A punishment is any consequence that decreases a
behavior - Ex. Jail time for stealing to stop a person from
doing it again - Presentation-should be directly after behavior to
be effective - Drawbacks-when punishment stops, behavior returns

18Social/Observational Learning
- Modeling- copying a persons behavior
- You must COPY a behavior not listen to
instructions and carry them out. - BoBo Doll experiment-done by Albert Bandura to
test the effect of modeling violence on children. - BoBo clip
19- Is violence on television making children more
violent? - Number of murders seen on TV by the time an
average child finishes elementary school8,000 - Number of violent acts seen on TV by age 18
200,000 - Count the violent acts in the following cartoon
clip. - http//www.youtube.com/watch?vHeG_LSrjIX4
20- E.C. Tolman believed that we all have a cognitive
map of our surroundings, meaning a mental map
that we create. - Latent learning-learning without direct effort,
such as remembering how to get to a place that
you have passed by but never directly tried to
get to.
