Unit 6 (learning) Flashcards
learned helplessness
the hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events
internal locus of control
the perception that you control your own fate
habituation
an organism’s decreasing response to a stimulus with repeated exposure to it
classical conditioning
a type of learning in which one learns to link two or more different stimuli and anticipate the same event
acquisition
In classical conditioning, the initial stage, when one links a neutral stimulus and an unconditioned stimulus
law of effect
Thorndike’s principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely
operant chamber
in operant conditioning research, a chamber (also known as a Skinner box) containing a bar or key that an animal can manipulate to obtain a food or water reinforcer; attached devices record the animal’s rate of bar pressing or key pecking.
reinforcement
in operant conditioning, any event that strengthens the behavior it follows
discriminative stimulus
a cue or signal that reinforces a behavior (ex- green light, “sit”)
positive reinforcement
addition of stimulus
negative reinforcement
removal of stimulus
primary reinforcer
an innately reinforcing stimulus, such as one that satisfies a biological need
conditioned reinforcer (secondary reinforcer)
a stimulus that gains its reinforcing power through its association with a primary reinforcer; also known as a secondary reinforcer (ex-money)
continuous reinforcement
reinforcing the desired response every time it occurs
partial (intermittent) reinforcement
reinforcing a response only part of the time; results in slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement
positive punishment
administer an aversive stimulus (ie. parking ticket)
negative punishment
withdraw a rewarding stimulus (ie. revoke library cards, take away teen’s driving priveleges)
biofeedback
a system for electronically recording, amplifying, and feeding back information regarding a subtle physiological state, such as blood pressure or muscle tension
operant behavior
behavior that is shaped due to consequences
cognitive map
a mental representation of the layout of one’s environment. For example, after exploring a maze, rats act as if they have learned a cognitive map of it.
learning
the process of acquiring new and relatively enduring information or behaviors
associative learning
learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning).
stimulus
any event or situation that evokes a response
