What is a Skinner box and what is its purpose?
A Skinner box is an operant conditioning chamber used to train animals such as rats and pigeons to perform certain behaviors, like pressing a lever. When the animals perform the desired behavior, they receive a reward: food or water.
Ivan Pavlov experiment
Classical conditioning with dogs and salivation. -would ring a bell (neural stimulus), present dog with food (unconditioned stimulus), and the dog would salivate (unconditioned response) -after doing this, the dog learns that bell (conditioned stimulus) means food and would salivate (conditioned response) without the food unconditioned stimulus (UCS) = food unconditioned response (UCR) = salivation conditioned stimulus (CS) = bell conditioned response (CR) = salivation in response to the bell
according to Albert Bandura, ___________
Learning can occur by watching others and modeling what they do or say.
taste aversion
a type of conditioning in which an interval of several hours may pass between the conditioned stimulus (something ingested) and the unconditioned stimulus (nausea or illness) ex: you get chicken curry for lunch and feel nauseous several hours later; the next time you hear someone order chicken curry, you immediately feel nauseous; the food has not made you nauseous, but the thought of it after one unpleasant experience results in aversion
operant conditioning
a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher
classical conditioning
a type of learning in which one learns to link two or more stimuli and anticipate events
stimulus discrimination
ability to respond differently to similar stimuli

What is shaping and how would you use shaping to teach a dog to roll over?
shaping is an operant conditioning method in which you reward closer and closer the approximations of the desired behavior; if you want to teach your dog to roll over, you might reward him first when he sits, then when he lies down, and then when he lies down and rolls on his back, and finally you reward him only when he completes the entire sequence of lying down, rolling onto back, and rolling to other side
Compare and contrast classical and operant conditioning.
-both classical and operant involve learning by association -classical conditioning: -responses are involuntary and automatic; -event that drives behavior (stimulus) comes before behavior; -involves an organism forming an association between involuntary response and stimulus -operant conditioning: -responses are voluntary and learned; -event that drives behavior (consequence) comes after behavior; -organism forming association between a voluntary behavior and a consequence
explain how the processes of stimulus generalization and stimulus discrimination are considered opposites
-stimulus generalization: organism responds to stimuli that are similar to the original conditioned stimulus -stimulus discrimination: when an organism learns a response to a specific stimulus, but does not respond the same way to a new stimuli that are similar
How does a neutral stimulus become a conditioned stimulus?
-through the process of acquisition (human/animal learns to connect a neural stimulus and unconditioned stimulus) -during acquisition phase, neutral stimulus is becoming conditioned stimulus -at end of acquisition phase, learning has occurred and the neutral stimulus becomes a conditioned stimulus capable of eliciting the conditioned response by itself
steps of shaping
1. Reinforce any response that resembles the desired behavior. 2. Then reinforce the response that more closely resembles the desired behavior. You will no longer reinforce the previously reinforced response. 3. Next, begin to reinforce the response that even more closely resembles the desired behavior. 4. Continue to reinforce closer and closer approximations of the desired behavior. 5. Finally, only reinforce the desired behavior. ex: teaching a son to clean his room - first have him pick up one toy, then five toys, then ten toys, then gets to pick to pick up all toys or put clothes away, then cleans everything except two toys, then cleans entire room
who proposed observational learning?
Albert Bandura (believed learning involved cognitive processes, not just strict behaviorism)
Edward C. Tolman
American psychologist who used the terms cognitive map and latent learning to describe experimental findings that strongly suggested that cognitive factors play a role in animal learning -debunked behaviorism's claim that reinforcement must be immediate in order for learning to occur ex: children learn by watching the actions of their parents but only demonstrate it at a later date

before: sickness during: food poisoning; sickness after: pizza; sickness
fixed interval reinforcement schedule
behavior is rewarded after a set amount of time (ex: after 5, 10, 15 and 20 mins) -moderate response rate with significant pauses after reinforcement ex: pt given IV drip with pt-controlled painkiller, her dr sets a limit (one dose per hour); pt pushes button when pain becomes difficult, and since the reward only occurs on fixed interval, there is no point exhibiting behavior when it will not be rewarded
variable interval reinforcement schedule
behavior is rewarded after unpredictable amounts of time have passed (ex: after 5, 7, 10, and 20 mins) -moderate yet steady response rate ex: a manager has no idea when a person from quality control will show up, so he strives to keep the store clean and his employees exhibiting prompt and courteous service bc he does not want to get in trouble with quality control

c. rewarding a child for finishing his oatmeal and counting how many times the child needs to be rewarded before he finishes his oatmeal voluntarily
classical vs operant conditioning
classical: an unconditioned stimulus (food) is paired with a neutral stimulus (bell); neutral stimulus eventually becomes the conditioned stimulus, which brings about the conditioned response (salivation); stimulus timing: stimulus occurs immediately before the response operant: target behavior is followed by reinforcement or punishment to either strengthen or weaken it, so that the learner is more likely to exhibit that desired behavior in the future stimulus timing: stimulus (either reinforcement or punishment) occurs soon after the response
In Pavlov's work with dogs, the "psychic secretions" were ________
conditioned responses (salivation upon hearing a bell)

A researcher is testing young children to see if they can learn to associate a red circle with an event that the child enjoys. She sets up an experiment where a toy bear dances. The infants love the dancing bear. She trains the child by showing a red circle on a screen in front of the child and, immediately after that, the bear appears and dances off to the side. The bear is only visible right after the red circle and the child must turn their head to see the bear. unconditioned stimulus: unconditioned response: conditioned stimulus: conditioned response: neutral stimulus: neutral response:
unconditioned stimulus: dancing bear unconditioned response: baby turns head conditioned stimulus: red circle conditioned response: baby turns head neutral stimulus: red circle neutral response: baby does not turn head
instinct
