Exam #2 Flashcards
A type of learning in which one learns to link two or more stimuli and anticipate events.
Classical Conditioning
People associate their own actions w/ consequences. Actions followed by reinforcers increase;those followed by punishments decrease.
Operant Conditioning
States that any behavior that is followed by pleasant consequences is likely to be repeated, and any behavior followed by unpleasant consequences is likely to be stopped.
Thorndike’s Law of Effect
Thorndike placed a cat in a box and encouraged it to escape to reach a fish outside the box. the cat would be timed how long it would take to find the lever to escape the box. the cat would get quicker and quicker
Puzzle Box
The box has something an animal presses to release a reward of food or water. it also records the respones. Rats and Pigeons acts out Skinner’s concept of reinforcement.
operant chamber/ skinner box
any event that strengthens(increases frequency of) a preceding response
Reinforcement
gradually guiding the rat’s( or other animal’s) actions toward the desired behavior.
Shaping
sometimes called “shaping.” the steps towards the final desired behavior must be identified in chronological order i need to complete the entire desired performance. Once the final behavior is split into desired steps by the trainer, steps can begin to be rewarded successively
Successive approximations
increasing behaviors by presenting a stimulus that, when presented after a response, strengthens the response.
positive reinforcement
increasing behaviors by stopping or reducing negative stimuli. any stimulus that, when removed after a response, strengthens the response ( not a punishment)
negative reinforcement
an innately reinforcer stimulus, such as one that satisfies a biological need.
primary reinforcer
a stimulus that gains its reinforcing power through its association with a primary reinforcer
conditioned (secondary) reinforcer
occurs immediately after desired response of an organism and the delivery of reward.
immediate reinforcer
a time delay between the desired response of an organism, and the delivery of reward
delayed reinforcer
used in both classical and operant conditioning. In classical conditioning, it refers to an ability to distinguish between a conditioned stimulus and other, similar stimuli that don’t signal an unconditioned stimulus
discrimination
ex) reward every hour ( slow unsustained responding)
fixed interval of reinforcement
reward after a changing/random amount of time passes (slow consistent responding)
variable interval schedule
reward every 5 targeted behaviors( high rate of responding)
fixed ratio schedule
reward after a randomly chosen instance of target behavior ( high consistent responding)
variable ratio schedule
decrease behavior vs attempt to increase behavior
punishment vs negative reinforcement
ADD something unpleasant
positive punishment
TAKE AWAY something pleasant/desired
negative punishment
the acquisition of mental information, whether by observing events, by watching others, or through language.
cognitive learning
a mental representation of the layout of one’s environment. Example, after exploring a maze, rats act as if they have learned a _ of it.
