Internal Locus of Control: consequences are a result of my own actions I studied hard so I did well on the test. I didn’t study hard enough so I failed the test. “I am the master of my fate; I am the captain of my soul” External Locus of Control: consequences are a result of other people’s actions, fate, etc. I had my lucky socks on so I did well on the test. The teacher didn’t teach us well enough so I failed the test. “You can’t fight fate.”

Vicarious Conditioning: The learning of various attitudes, feelings, beliefs and emotions, not through direct exposure to a stimulus, but through observing how others react to it. Your friend tells you a vivid story of getting bit by a snake. He/she is sweating, shaking, etc. as the story is being told. You now are afraid of snakes. You see your sister get struck by lightning. You now have a fear of thunder storms.

Higher Order Conditioning (also known as Second Order Conditioning): Conditioning using a previously-conditioned CS Advertisers use this by pairing images that evoke good feelings with images of their product(s)

The Acquisition Period (Timing) Consideration #1: How much time passes between the conditioned stimulus (neutral) and the unconditioned stimulus (automatic). This will usually be a matter of seconds. The shorter the time lapse, the more likely the organism is to associate the conditioned stimulus with the unconditioned stimulus. If too much time passes, the association will never be made – conditioning will not take place. Consideration #2: The number of times the conditioned stimulus (neutral) and the unconditioned stimulus (automatic) must be paired for the association to be made, and for a conditioned response to occur. What Determines Whether & How a Conditioned Response is Learned??? TIMING - PREDICTABILITY - SIGNAL STRENGTH - ATTENTION Immediate - Consistent - Severe - Attentive Inconsistent (slow Acquisition/Extinction) Timing is Everything!

The Concept of Reinforcement Reinforcement is said to occur when a stimulus follows an operant and increases the likelihood of the operant being repeated. (+) Positive Reinforcement (-) Negative Reinforcement Involves following an operant with the addition of an appetitive stimulus A response is strengthened because something is added Involves an operant that is followed by the removal of an aversive (unpleasant) stimulus. Response is strengthened because something is subtracted Usually involves (1) escaping aversive stimuli (2) avoiding aversive stimuli All Reinforcements (Positive & Negative) Increase The Likelihood That The Behavior Will Occur Again In Future Situations.

8 Examples of Negative Reinforcement Taking aspirin (operant) to relieve a headache (stimulus). Hurrying home in the winter (operant) to get out of the cold (stimulus). Giving in to a dog’s begging (operant) so that it stops barking (stimulus). Setting a timer on the oven (operant) to avoid burning the cookies (stimulus). Leaving a movie theatre (operant) to escape the movie (stimulus). Following prison rules (operant) in order to be released (stimulus). Faking a stomachache (operant) in order to avoid school (stimulus). Putting up an umbrella (operant) in order to escape the rain (stimulus).

The Concept of Punishment Punishment is a process in which a behavior is followed by an aversive consequence that decreases the likelihood of the behavior being repeated. (-) Negative Punishment (+) Positive Punishment Also called punishment by removal Some stimulus is subtracted or removed Loss or withdrawal of an appetitive stimulus following a behavior The behaviors consequence is the loss of some privilege, possession, or other desirable object or activity Also called punishment by application Response is followed by the presentation of an aversive stimulus “Positive” signifies that something is added or presented in the situation The stimulus is typically aversive All Punishments (Positive & Negative) Reduce The Likelihood That The Behavior Will Occur Again In Future Situations

Considerations in Using Punishment Punishment in itself does not teach alternate acceptable behavior. Punishment works only when applied consistently. Severely punished individuals may attempt to leave the environment. Intense punishment can create anger and hostility. Punishment may not be understood (especially by children). Punishment may be imitated as a way to solve problems and conflicts. Punishment could make the behavior occur more frequently.

Positive Reinforcement (Something Unpleasant) The Consequence Matrix Stimulus Type Add a Stimulus Remove a Stimulus Appetitive Stimulus (Something Desired) Positive Reinforcement Negative Punishment Aversive Stimulus (Something Unpleasant) Positive Reinforcement Positive & negative reinforcement increase the frequency of a behavior (the operant). Positive & negative punishment decrease the frequency of a behavior (the operant). Negative reinforcement involves the removal of an aversive stimulus in order to increase the likelihood of a behavior. Punishment involves the removal of an appetitive stimulus (negative) or addition of an aversive stimulus (positive) in order to decrease the likelihood of a behavior.

How do you reinforce a behavior That is not part of the organism’s Natural behavioral repertoire? Definitions of Shaping (Successive Approximations) Examples of Shaping (Successive Approximations) Shaping is reinforcing successive approximations of the desired response. Shaping is the process of teaching a complex behavior by rewarding closer approximations of the desired target behavior. Shaping through successive approximations involves reinforcing any response that successively approximates and ultimately matches the desired response. Rats don’t press levers!

FRQ James is in a driver’s education course preparing to take his driving test. The course includes both book work and driving on the road to prepare students for a written test and a road test. (a) Describe how each of the following might influence his ability to drive a car during the road test. Definitions without application do not score. *Cognitive map (the maps/directions in our mind) *Cerebellum (balance/body movement and coordination) *Observational learning (learning by watching others)  (b) Describe how each of the following are related to the results of the written test. Definitions without application do not score. *Reticular formation in the brainstem (helps eyes to move/fixate on objects, relays ear/eye signals, alertness/sleepiness) *Semantic memory (facts)
