Learning
long-lasting change in behavior that comes about due to the individual’s experience
Instinct
is a fairly elaborate pattern of behavior that is shown by all members of a species
* not learned
Reflex
a simple pattern of behavior that does not involve the brain, but only a simple connection in the spinal cord
* not learned
Habituation
simplest form of learning
* is a decrease in response to a repeated stimulus
Classical conditioning
basic form of learning in which existing reflex responses come to be elicited (caused) by new stimuli
Pavlov
observed that meat powder caused reflex salivation
* Pavlov rang a bell; initially the bell was a neutral stimulus
* he placed meat powder on the dog’s tongue
* after this sequence was repeated many times, the bell alone began to cause salivation
by association, the bell which before had no effect, began to produce the same response that the food did
Neutral stimulus
stimulus that does not evoke a response
Unconditioned stimuli
produce reflexive responses or involuntary emotional reactions
Extinction
the gradual decline and disappearance of a conditioned response when it is no longer reinforced
Spontaneous recovery
the reappearance of an extinguished response upon returning to the familiar situation and the conditioned stimulus
Unconditioned response
response that will occur without previous conditioning
Conditioned stimulus
a previously neutral stimulus that has, through conditioning, acquired the capacity to elicit a conditioned response
Conditioned response
the response which is elicited by the conditioned stimulus
Stimulus generalization
the tendency for a conditioned response to be evoked by similar stimuli or situations
Stimulus discrimination
the learned ability to detect differences among stimuli and to respond differently to each
Operant conditioning or instrumental learning
a form of learning in which a voluntary response is strengthened or diminished by its consequences
Operant
a response that has some effect
Reinforcer
increases the probability that a behavior will occur again
Law of Effect
acts that are reinforced (rewarded) tend to be repeated
responses that are followed by satisfying consequences increase in probability
Primary reinforcers
satisfy biological needs
Secondary reinforcers
depend on learning
Watson’s theory
three basic human emotions: fear, rage, and love, which get transferred to other situations through classical conditioning
Skinner box
conditioning chamber used to “teach” operant conditioning
Positive reinforcement
- reward
*increases responding
Negative reinforcement
occurs when making a response removes an unpleasant event
* ends discomfort
Reinforcement
increases the rate of a response
Punishment
decreases the rate of a response
Continuous reinforcement
- one behavior, one reinforcement
- quickest way to teach a behavior
- quickest to extinguish
