Q

classical conditioning

A

Classical conditioning is a type of associative learning that takes advantage of biological, instinctual responses to create associations between two unrelated stimuli.

Classical conditioning works, first and foremost, because some stimuli cause an innate or reflexive physiological response. For example, we reflexively salivate when we smell bread baking in an oven, or we may jump or recoil when we hear a loud noise.

Q

neutral stimuli

A

sound of bell for dogs before learning. No reason it would have salivated uncontrollablly. Or a song that hasnt been associated with something in your life

causes no response related to the unconditioned pair

Q

ivan pavlov experiment

A

trained dogs to associated the neutral stimulus (bell) with the unconditioned stimulus of bringing food at feeding time. The dogs would unconditionally (innately) salivate at food. By introducing bell at same time as the food the dogs associated the bell with food. Ultimately the conditioned stimulus of the bell (once neutral) could trigger saliva production without food

Q

operant conditioning

A

Operant conditioning, sometimes referred to as instrumental conditioning, is a method of learning that uses rewards and punishment to modify behavior. Through operant conditioning, behavior that is rewarded is likely to be repeated, and behavior that is punished will rarely occur.

Operant conditioning is associated with B. F. Skinner, who is considered one of the founders of behaviorism, the theory that all behaviors are conditioned

17
Q

punishment in operat conditioning

A

punishment is any change in a human or animal’s surroundings which, occurring after a given behavior or response, reduces the likelihood of that behavior occurring again in the future.

adding - makes it positive punishment
scolding a kid after cursing

removing - makes it negative punishment
removing a cell phone

18
Q

Escaping and avoiding in operant conditioning

A

Escape learning describes a situation where the animal experiences the unpleasant stimulus and, in response, displays the desired operant behavior in order to trigger the removal of the stimulus.

avoidance learning occurs when the animal displays the desired behavior in anticipation of the unpleasant stimulus, thereby avoiding the unpleasant stimulus.
(often develops with multiple expierences of escape learning)

19
Q

examples of reinforcement schedule

A

fixed ratio - child recieved a reward after cleaning a certain number of times (#)

continuous reinforcement -fixed ratio schedule where behavior is rewarded EVERY time it is performed

fixed interval - child recieved a reward after cleaning after period of (TIME)

variable ratio - child recieves a reward after # of cleaning dishes after varying number (she cant be sure). But overal average is consistent (ex, 2, 4, 8, 6)

variable interval - child recieves a reward after a random period of time (1 day, 2 weeks)

20
Q

which reinforcement schedule is the most addictive?

A

variable schedules are most resistant to extinction

fixed ratio is less addictive
variable ratio is best, then variable interval

Very Rapid and Very Resistant to extinction
VR for Variable Ratio

21
Q

latent learning

A

learning that reveals itself once a reward is introduced

incentivized to get good grades for a reward offered

22
Q

problem solving

A

apply knowledge learned

23
Q

biological prepardness

A

how inclined an animal is to learn a behavior necessary for survival
(occurs via predisposition)

a bird needs to peck when searchign for food, rewarding food in response to pecking works well for learning a task

24
Q

instinctive/instinctual drift

A

reverting to an innate behavior

trained dog bark at intruders

25
Q

associative learning

A

associative learning is the creation of a pairing, or association, either between two stimuli or between a behavior and a response.

On the MCAT, you’ll be tested on two kinds of associative learning: classical and operant conditioning.

26
Q

what is aquisition?

A

The process of using a reflexive, unconditioned stimulus to turn a neutral stimulus into a conditioned stimulus is termed acquisition

Q

4 possible relationships in operant conditioning

Q

example of avoidance learning with a seat belt warning in a car

A

Avoidance learning often develops from multiple experiences of escape learning. An example of this progression from escape learning to avoidance learning is the seat belt warning in a car. If a driver begins driving without buckling the seat belt, then the car will produce an annoying beeping noise, which only ends when the seat belt is buckled. In this example, the desired behavior is to buckle the seat belt. This behavior is reinforced by the removal of an unpleasant stimulus (the audible beeping), so this type of learning is negative reinforcement. More specifically, this example illustrates escape learning, since the driver first experiences the unpleasant stimulus, then exhibits the desired behavior in order to escape the unpleasant stimulus. However, after forgetting to buckle the seat belt several times, the driver will eventually learn to preemptively buckle up before driving the car in order to avoid the beeping sound. At that point, the escape learning has progressed to avoidance learning. Finally, this example illustrates an important misconception about the term negative reinforcement: Buckling one’s seat belt is generally considered a “positive” behavior, in that it protects one’s health. Nevertheless, the terms “positive” and “negative” in operant conditioning only refer to the addition or removal of a stimulus. So even though buckling up is a “good” thing, this example illustrates several types of negative reinforcement!

29
Q

how can classical and operant conditioning be paired?

A

in dog training when trainers use reinforcers when training dogs to preform tricks

, the trainers will feed the dog a bit of meat after it performs a trick. The meat can be said to be a primary reinforcer because the meat is a treat that the dog responds to naturally.

Dog trainers also use tiny handheld devices that emit a clicking sound. This clicker would not normally be a reinforcer on its own, but the trainers use classical conditioning to pair the clicker with meat to elicit the same response. The clicker is thus a conditioned reinforcer, which is sometimes called a secondary reinforcer

Eventually, the dog may even associate the presence of the trainer with the possibility of reward, making the presence of the trainer a discriminative stimulus. A discriminative stimulus indicates that reward is potentially available in an operant conditioning paradigm.

30
Q

discriminative stimulus

A

in operant conditioning, a stimulus that increases the probability of a response because of a previous history of differential reinforcement in the presence of that stimulus. For example, if a pigeon’s key pecks are reinforced when the key is illuminated red but not when the key is green, the red stimulus will come to serve as an SD and the pigeon will learn to peck only when the key is red.

31
Q

negative reinforcement vs positive punishment

A

Negative reinforcement is the removal of a bothersome stimulus to encourage a behavior; positive punishment is the addition of a bothersome stimulus to reduce a behavior.

32
Q

averse conditioning

A

Aversive conditioning is a type of classical conditioning in which an unwanted behavior is targeted by pairing it with a negative stimulus in an attempt to reduce the unwanted behavior.

33
Q

formal sanctions and informal sanctions on behavior

A

formal sanctions - rules, laws, reinforce or punish behavior
informal sanctions - ostracization, praise, shunning can reinforce or punish behavior

34
Q

shaping in operant conditioning

A

shaping, which is the process of rewarding increasingly specific behaviors that become closer to a desired response.

For example, if you wanted to train a bird to spin around in place and then peck a key on a keyboard, you might first give the bird a treat for turning slightly to the left, then only for turning a full 90 degrees, then 180, and so on, until the bird has learned to spin around completely. Then you might only reward this behavior if done near the keyboard until eventually the bird is only rewarded once the full set of behaviors is performed. While it may take some time, the use of shaping in operant conditioning can allow for the training of extremely complicated behaviors

35
Q

observational learning

A

Observational learning is the process of learning a new behavior or gaining information by watching others. via modeling

The most famous and perhaps most controversial study into observational learning is Albert Bandura’s Bobo doll experiment, in which children watched an adult in a room full of toys punching and kicking an inflatable clown toy. When the children were later allowed to play in the room, many of them ignored the other toys in the room and inflicted similar violence on the Bobo doll just as they had seen the adult do.

In later iterations of the Bobo doll experiment, children who watched the adult get scolded after attacking the Bobo doll were less likely to be aggressive toward the Bobo doll themselves.

36
Q

mirror neurons

A

These neurons are located in the frontal and parietal lobes of the cerebral cortex and fire both when an individual performs an action and when that individual observes someone else performing that action. Mirror neurons are largely involved in motor processes, but additionally are thought to be related to empathy and vicarious emotions; some mirror neurons fire both when we experience an emotion and also when we observe another experiencing the same emotion.

37
Q

BF Skinner experiment

A

Skinner showed how negative reinforcement worked by placing a rat in his Skinner box and then subjecting it to an unpleasant electric current which caused it some discomfort. As the rat moved about the box it would accidentally knock the lever. Immediately it did so the electric current would be switched off.

38
Q

which is an example of avoidance learning

father wears a knee brace
“i notived by knees hurt, and it reduces pain”

“i am going for a run and want to prevent future knee injuries from happening”

A

“i am going for a run and want to prevent future knee injuries from happening”

engage in one behavior to avoid undeseriable outcome

other scenario does avoid the outcome

39
Q

operant vs classical

A

operant - reward or punishment
classical - stimulus and response
