consciousness
everything of which we are aware at any given time
circadian rhythms
-the regular fluctuation from high to low points over 24 hours
-sleep/wakefulness cycle
-daily fluctuation in body temperature (active when high, sleep when low)
suprachiasmatic nucleus
-located in brain's hypothalamus
-SCN for short
-biological clock that controls circadian rhythms as well as other kinds of timekeeping mechanisms in the brain

-more than 50% delta waves, may reach 100%
-deepest sleep
-hardest to awaken
-40 minutes, then go back through stage 3, stage 2, and enter REM (10-15 minutes)
-no more stage 4 sleep after 2 cycles, alternate between stage 2 and REM, REM gets longer and longer (last one 30-40 minutes)

-an organism learns to associate one stimulus with another
-pavlovian conditioning
-respondent conditioning
stimulus
--any event or object in the environment to which an organism responds
unconditioned response
-a response coming from an unconditioned stimulus w/out prior learning
unconditioned stimulus
-any stimulus (food) that will bring about an unconditioned response
conditioned stimulus
-after repeated pairing with an unconditioned stimulus, becomes associated with it, and creates a conditioned response
conditioned response
-a learned response that is elicited from a conditioned stimulus as a result of its repeated pairing with an unconditioned stimulus
higher order conditioning
-a neutral stimulus can become a conditioned stimulus just from pairing it with a previously acquired conditioned stimulus. (steps leading up to shot)
extinction
-weakening of the conditioned response
spontaneous recovery
-reappearance of extinguished response in a weaker form following the resting period
generalization
-the tendency to make a conditioned response to a similar stimulus
discrimination
-the learned ability to distinguish between similar stimuli so that the conditioned response occurs only to the original conditioned stimuli

(people on salary rather than hourly rate, causes scalloping)
-lowest response rate
-long pause after reinforcement, followed by gradual acceleration
-the longer the interval, the more resistance to extinction
variable interval schedule
-a reinforcer is given after the first correct response following a varying time of nonreinforced responses based on an average time.
(random drug testing)
-moderate response rate
-stable, uniform response
-more resistance to extinction than fixed-interval schedule with same average interval
shaping
-gradually molding a desired behavior (response) by reinforcing any movement in the direction of the desired response, gradually guides the responses toward the ultimate goal
