1

reflex

  • motor/neural reaction to a stimulus in the environment

  • simpler than instincts, involving body systems

    • eg: knee jerk reflex, pupil dilating, sucking reflex

  • primitive centers of central nervous system (spinal cord and medulla)

New cards
2

instincts

  • innate behaviors triggered by a broader range of events

  • maturation, change of seasons

  • complex patters including the movement of the organism as a whole

  • involve higher brain centers

    • sexual activity, migration, hibernation

New cards
3

learning

  • permanent change in behavour or knowledge resulting from experince

    • involes acquriing knowledge

New cards
4

associative learning

  • minds have a natural tendancy to connect events closley together

  • occours when organism makes connections betweens stimuli or events that occour together in the enviroment

    • used in conditioning

New cards
5

classical conditioning

  • Ian pavlov (1849-1936): dogs salivating to the ring of a bell, assosiated with food

  • associate stimuli that are repeated together

  • a neutral stimulus is presented immediately before an unconditioned stimulus.

New cards
6

unconditioned stimulus

  • a stimulus that elicits a reflexive response in an organism

  • eg: the smell of food

New cards
7

unconditioned response

  • a natural unlearned reaction to a stimulus

    • eg: salivation

New cards
8

neutral stimulus (NS)

  • stimulus that does not naturally

  • eg: ringing a bell

  • when paired with and repeated with stimulus (becomes conditoned) , results in reponse

New cards
9

conditioned response

  • simulus that ilicits a response after being repeatdly paired with a unconditoned stimulus

    • eg: dogs associated the bell (CS), salivate (CR) in anticipation of food

New cards
10

higher-order conditioning (second order conditioning)

  • pairing a new stimulis with the condtioned stimulus

  • using the condtioned stimulus to condition another stimulus

  • hard to acheive anything above 2nd order conditioning

    • blowing a horn every time the bell rights for food, dog will not get excited hearing bell alone

New cards
11

acquisition

  • when an organism learns to connect a neutral stimulus and an unconditioned stimulus

  • timing is key: there should only be a brief interval between condtioned stimulus and uncondtioned stimulus

    • usally as little as 5 seconds sometimes up to hours

New cards
12

taste aversion:

  • interval of several hours between ingestion (conditioned stimulus) and unconditioned stimulus (nausea or illness)

  • can occur in a single instance due to evolutionary adaptation to avoid harmful foods

    • survive via natural selection

New cards
13

Extinction

decrease in conditioned response when unconditioned stimulus is no longer presented together with conditioned reponse

  • gradual wekening and disapperance of the conditoned reponse

    • eg: ring bell no food provided

New cards
14
<p><span><strong>spontaneous recovery</strong></span></p>

spontaneous recovery

  • the return of a prevously extinguished conditoned repsonse following a rest period

New cards
15

stimulus discrimination

  • need to distinguish between stimuli to respond appropriately when an organism learns to respond different to various stimuli that are similar

  • involved in determining which stimuli will trigger learned responses

    • eg: salivating at bell and not a doorbell

New cards
16

Behavoirism

  • John B watson founder of behavoirism

  • focus on outword observable behavoir that can be measured contrasting freuds theories on unconcious

  • influenced by pavlov

  • little albert: exposed to loud noises when playinf with animals conditoning a phobia

New cards
17

operant conditioning

  • organisms learn to associate a behavior and its consequence

  • punsihment vs reward stimulus

    • occours soon after response

New cards
18

law of effect

  • BF. Skinner

  • consequences that are satisfying to the organism are more likely to be repeated, and behaviors that are followed by unpleasant consequences are less likely to be repeated

    • eg: showing up to work because of pay

New cards
19

skinner box

  • animal press for food reward

    • counts respones made by animal

New cards
20

positive reinforcment

  • Something is added to increase the likelihood of a behavior

    • eg: giving treat to a dog who sits to continue such behavoior

New cards
21

negative reinforcement

  • something is removed to increase the liklehood of a behavior

    • eg: plugging in seatbelt to remove annoying beep sound

New cards
22

Positive punishment

Something is added to decrease the likelihood of a behavior.

  • eg: spanking a kid to decrease stealing

New cards
23

Negative Punishment

Something is removed to decrease the likelihood of a behavior.

  • taking away a toy if kid misbehaves

New cards
24

pros and cons of punishment

pros

  • effective, person is less likley to do

con

  • instills fear towards person who delivered punsihment

    • can mkae child more agressive, antisocial and use the same behavoir on others

New cards
25

shaping

  • skinner used in his operant condiutioning experirments

  • reward successive approximants of a target behavoir

  • reifnrces any response that resembles the desired behavoir

    • reinforce closer and closer approximations of the desired behavoir, until only reinfocing the desired behavoir

  • skinner used to teach pigeons behaovirs such as turning in circles, playing ping pong etc

New cards
26

primary reinforcer.

  • are reinforcers that have innate reinforcing qualities.

  • These kinds of reinforcers are not learneed

    • Water, food, sleep, shelter, sex, and touch, plrasureamong others, are primary reinforcers.

New cards
27

secondary reinforcer

has no inherent value and only has reinforcing qualities when linked with a primary reinforcer.

  • praise is linked to affection

  • money is linked to buy needs

New cards
28

continuous reinforcement

  • When an organism receives a reinforcer each time it displays a behavior

  • the quickest way to teach someone a behavior

  • effective in teaching new behavoir

    • eg: each time rat presses button it gets food

New cards
29

partial reinforcement

  • intermittent reinforcement

  • does not get reinforced every time they perform the desired behavior

    • diffrent schedules: fixed, variable, interval, ratio

New cards
30

Fixed interval

  • Reinforcement is delivered at predictable time intervals

  • higher qualirt of output

  • results in moderate response rate with signficant pauses after reinfocement

    • eg: patient presses button for morphine which is docter timed

New cards
31

Variable interval

Reinforcement is delivered at unpredictable time intervals

moderate yet steady response rate

eg: checking social media, not knowing when manager will come

New cards
32

Fixed ratio

Reinforcement is delivered after a predictable number of responses

  • high response rate with pauses after reinforcments

  • quantity based

  • worker getting paid for every x number of items manufactured

New cards
33

Variable ratio

Reinforcement is delivered after an unpredictable number of responses

  • high and steady response rate

  • eg: gambling

New cards
34

radical behavoirism

  • Skinner was such a staunch believer that cognition didn't matter

  • considered the mind a "black box"—something completely unknowable— not to be stuided

New cards
35

cognitive map

As the unreinforced rats explored the maze, they developed a cognitive map: a mental picture of the layout of the maze

New cards
36

latent learning:

learning that occurs but is not observable in behavior until there is a reason to demonstrate it.

  • exiting the maze onlydue to food (shupid rat),

New cards
37

observational learning

  • learn by watching others and then imitating, or modeling, what they do or say

  • eg: chimpanizes, humans

New cards
38

models

The individuals performing the imitated behavior

New cards
39

Albert Bandura

  • the scientists behind:

  • pure behaviorism could not explain why learning can take place in the absence of external reinforcement.

  • internal mental states must also have a role in learning and that observational learning

3 kinds of models

  • live: behaovir inperson

  • verbal: explains behaovir such as a coach

  • symbolic: books, movies etc

New cards
40

vicarious reinforcement

occurs when learners observe role models receiving either positive or negative reinforcement

  • behavior, you will be more motivated to copy them.

New cards
41

vicarious punishment

hand, if you observed the model being punished, you would be less motivated to copy them.

New cards
42

Bobo doll

  • When the teacher was praised or ignored (and not punished for her behavior), the children imitated what she did, and even what she said.

  • when the teacher was punished for this behavoir they were less likley to

  • whem teacher was praised, They punched, kicked, and yelled at the doll too

conclusion: Bandura concluded that we watch and learn, and that this learning can have both prosocial and antisocial effects.
