Q

What does behaviourism focus on regarding learning?

A

Focuses on how organisms learn (the laws of learning)

view organisms as “tabula rasa” (a blank state) until learning takes place

study animals in the lab

Q

What is habituation? give an example.

A

a decrease in the strength of a response to a repeated stimulus (most simple form of learning)

wearing a shirt, your body habituates it and you cease to be aware of it.

Q

Q

What are the 4 important elements to classical conditioning?

A

CR - conditioned response (elicited by CS)

Q

What are the four types of CS-UCS pairings?

A

FORWARD SHORT DELAY: (fastest)
CS appears first and is still present when UCS presented

FORWARD TRACE:
CS appears then stops before UCS is presented

SIMULTANEOUS:
CS and UCS presented at same time

BACKWARD: (learning is slowest or does not occur at all)
CS presented after UCS

Q

What factors might enhance acquisition?

A
  • when forward short-delay pairing is used

Q

What is extinction? give an example.

A

occurs when CS is presented in absence of UCS

with each exposure the CR is weakened

ex: tone presented without presenting the food. Dog will not salivate after a time

Q

What is spontaneous recovery?

A

the reappearance of a previously extinguished CR after a rest period.

ex. fear at a certain location. extinguished by repeated exposure without adverse consequences. Take a break and bring them back they may experience fear again

Q

What is generalization?

A

when stimuli similar to the initial CS elicit a CR

ex tone causes salivation. Use a different tone and salivation occurs.

Q

What is discrimination?

A

when the CR occurs to one stimulus but not to another

ex. afraid of spiders. see a toy spider and not afraid of it

Q

What is higher order conditioning?

A

It is when an established CS becomes established with a neutral stimulus that becomes a CS evoking the CR

ex. tone elicits salivation. Tone now paired with a black square. after a time black square will elicit salivation.

Q

What can be said about higher-order conditioning when compared to classical conditioning?

Study These Flashcards
A

it is much weaker and easier to extinguish

20
Q

What is exposure therapy?

Study These Flashcards
A

rids the patient of phobias

therapy that exposes the patient to the feared stimulus (CS) without any UCS allowing extinction to occur

21
Q

What are the three types of exposure therapies?

Study These Flashcards
A

SYSTEMATIC DESENSITIZATION:
helped to relax, then exposed to the fear provoking stimulus

FLOODING:
immediately exposes the person to the stimulus

VR EXPOSURE:
expose to the CS virtually where the pt can feel safe

22
Q

What is aversion therapy?

Study These Flashcards
A

therapy which attempts to condition a repulsion to a stimulus

ex. alcoholics taking a drug that makes them sick when they drink

23
Q

What are some other influences of classical conditioning?

Study These Flashcards
A
  • attraction to other people
  • positive/negative engrained attitudes
  • anticipatory nausea and vomiting
24
Q

What is Thorndike’s law of effect?

Study These Flashcards
A
  • if there is a satisfying consequence, the behaviour is more likely to occur
  • if there is an unsatisfying consequence, the behaviour is less likely to occur

based on instrumental learning

25
What is instrumental learning?
when an organism's behaviour is instrumental in bringing about certain outcomes ex. a rat pushing a button to get food
26
Who led the field of study on operant conditioning?
SKINNER: | believed operant conditioning facilitates personal adaptation
27
What two types of consequences did Skinner identify in operant conditioning?
REINFORCEMENT: response strengthened by outcome that follows PUNISHMENT: response weakened by outcome that follows
28
What are the 3 kinds of events or ABCs of operant conditioning?
A: antecedents of behavior (stimuli that are present before behaviour) B: behaviours that the organism emits C: consequences that follow behaviour if A is present and B is emitted then C will occur
29
What is a discriminative stimulus?
a signal that a particular response will now produce certain consequences ex. food is dispensed by pressing a lever only when a light is on
30
What are the two types of reinforcement? give an example
POSITIVE reinforcement: response occurs -> stimulus is presented -> response increases NEGATIVE reinforcement: response occurs -> an aversive stimulus is removed -> response increases ex of neg, take an advil, headache goes away, increased tendency to take advil for headaches
31
What is the difference between primary and secondary reinforcers?
PRIMARY: biological needs (food, drink) SECONDARY: associated with primary reinforces (money)
32
What is operant extinction?
weakening and eventual disappearance of an operant response due to no longer reinforcing the response
33
What are the two types of punishment?
POSITIVE punishment: response weakened by adding a stimulus after (ex spanking) NEGATIVE punishment: response weakened by removal of stimulus (ex loss of privileges/money)
34
Which type of punishment makes a child less likely to be aggressive later in life?
negative punishment
35
What are the two types of gratification? Which is stronger?
IMMEDIATE: stronger effect on behaviour DELAY OF GRATIFICATION - involves the ability to forego immediate reward for outcome later - it is learned - individual variability
36
What is shaping?
SHAPING: reinforce the organism when he makes an approximation towards a goal ex. a boy is selectively mute and your goal is to get him to talk with other people. begin by reinforcing him when he says one word in front of others and gradually work up to a desired behaviour
37
What is chaining?
CHAINING: a procedure used to develop a chain of responses by reinforcing each response with the opportunity to perform the next response. ex. a rat learns to push a lever to get food. then a light is added and the rat will learn to only pull the lever when the light comes on. then a bell is added and the rat learns that when it bumps the bell it turns on the light allowing him to push the lever to get the food
38
What are the two types of schedules of reinforcement?
CONTINUOUS REINFORCEMENT: every response is reinforced PARTIAL REINFORCEMENT: some responses are reinforced
39
What are the 4 types of partial reinforcement schedules?
RATIO: certain percentage of responses are reinforced INTERVAL: reinforcement is limited by time. ex once per minute FIXED: after a fixed number of responses VARIABLE: after an average number of responses or time so can have fixed ratio, fixed interval, variable ratio, variable interval
40
What are the differences in results of continuous and partial reinforcement?
CONTINUOUS: - rapid learning - more rapid extinction PARTIAL: - slower learning - more resistant to extinction especially VR schedule
41
Why is gambling such a difficult habit to break?
because it is on a variable ratio reinforcement schedule
42
Explain escape and avoidance conditioning.
ESCAPE conditioning: learn responses to terminate aversive stimuli ex. putting on a coat when cold AVOIDANCE conditioning: learn responses to avoid aversive stimuli ex putting on a coat before you go outside so you do not get cold
43
What is the two-factor theory of avoidance?
it theorizes that both classical conditioning and operant conditioning in avoidance conditioning
44
What are the 4 steps in the modeling process of learning?
attention retention reproduction motivation
45
Who developed the modeling process of learning?
bandura
46
What is biological preparedness?
the predisposition (biologically) to learn behaviours related to survival behaviours that are contrary to our natural tendencies are slowly learned if at all
47
how is biological preparedness related to phobias?
most phobias develop things that have evolutionary significance like snakes, spiders, dangerous places few phobias exist for harmful man made things like guns, knives, cars
