What is the placebo effect? What can be the solution?

Q

Experiment Bias. Solution?

A

Actions made by the experimenter that could affect the results by accident. So, it’s better that the experimenter doesn’t know which group the participants belong to.

33
Q

CS+ and CS-

A

CS+ presence of stimuli and CS- absence of stimuli

34
Q

Systematic desensitization

A

uses gradually exposure to fear to the fear stimulus to make the phobia disappear.

35
Q

Sensitization

A

Increase in behavioural responding to a repeated stimulus

36
Q

What are two non-associative learning?

A

habituation and sensitization

37
Q

Two associative learning

A

classical conditioning and operant conditioning

38
Q

Operant learning

A

learn that a behaviour leads to a particular outcome

Ex: money into vending machine will give me candy

39
Q

Homeostasis

A

Body always tries to stay normal so that it evens out. That’s why classical conditioning happens

40
Q

Homeostasis

A

Body always tries to stay normal so that it evens out. That’s why classical conditioning happens

41
Q

CNS stands for

A

Compensatory Responses

42
Q

Drug addicts that take regular drugs and are used to it. Then they take the same doses and the overdose(enigmatic opiate overdose). Why?

A

The administration cues(environmental factors) are not present. The body is not ready even though it took that dose every single day.

43
Q

Inhibition

A

Makes the original learned response (CS) less likely by introducing a learned inhibitory response

44
Q

Presenting the CS+ and CS- simultaneously

A

Leads to an intermediate response

45
Q

What is higher-order conditioning?

A

Two or more conditioned stimuli can elicit the same conditioned response; however the conditioned response produced by the original CS is more resistant to extinction

46
Q

Compensatory response

A

A natural body response to maintain homeostasis (ex: sweating when hot)

47
Q

Discrimination

A

Restricting the range of CSs that can elicit CR

48
Q

Extinction

A

The loss of CR when CS no longer predicts CR. So CS is presented without US so the individual doesn’t expect CR/UR anymore

49
Q

Systematic desensitization

A

A mechanism used to treat phobias, in which the individual is presented with gradual exposure to the feared Cs without exposure to US

50
Q

Withdrawal

A

A group of symptoms occurring after a discontinuation of a medication or drug. Often happens when an individual is in the environment they previously took drugs.

51
Q

Instrumental conditioning

A

involves explicit training to learn the contingency between the voluntary behaviours and their consequences

52
Q

Law effect

A

Behaviours with positive consequences become stamped in and behaviours with negative consequences are stamped out

53
Q

Reinforcer

A

Any stimulus that is presented after a response that impacts the frequency that the response is performed.

54
Q

1.Reward training 2.punishment training 3.Omission training 4.escape training

A
  1. presentation of + reinforcement
  2. Presentation of - reinforcement
  3. Remove a + reinforcer
  4. Remove a - reinforcer
55
Q

Chaining

A

a technique used to develop a sequence of behaviours. Each behaviour is reinforced with the opportunity to perform the next behaviour in a sequence. (ex; learning the alphabet)

56
Q

Shaping by successive approximation

A

small behaviours that lead to the final complex behaviours. Each little behaviour can be reinforced. (reinforcement in the basis of improvement)

57
Q

SD/S+

A

when the contingent relationship is valid

58
Q

S&/S-

A

When contingent relationship is not valid

59
Q

Partial reinforcement

A

A schedule in which a form of reinforcement is not presented every time a particular behaviour is performed

60
Q

Ratio reinforcement

A

A schedule of reinforcement in which reinforcement is provided once a predetermined number of responses has been provided

61
Q

Interval schedule

A

A schedule of reinforcement in which reinforcement is provided once some amount of time has passed since the last response was reinforced

62
Q

what is fixed ratio?

A

Instrumental schedule where reinforcement is delivered after a constant number of responses

63
Q

Fixed interval

A

Instrumental schedule of reinforcement in which reinforcement is delivered after a constant period of time

64
Q

Variable ratio

A

Instrumental schedule of reinforcement where reinforcement is delivered after some variable number of responses around a characteristic mean

65
Q

Variable interval

A

schedule in which reinforcement is delivered after some variable period of time around a characteristic mean

66
Q

Continuous reinforcement

A

schedule of reinforcement in which reinforcement always follows a particular behaviour.

67
Q

What are the two assumptions psychologists make about intelligence?

A
  • ability to perform cognitive tasks

- The capacity to learn from experience adapt

68
Q

Deductive reasoning

A

From ideas and general info to specific conclusions

69
Q

Inductive reasoning

A

moving from specific facts to broader theories

70
Q

Functional fixedness

A

a bias limiting views to using an object only in the way it is traditionally used

71
Q

Reliability

A

measures the extend to which repeated testing give consistent results

72
Q

Validity

A

a valid test actually measures the trait it is supposed to be measuring

73
Q

Describe strong role of genetics in intelligence

A
  • Twins: correlation between IQ’sis +0.8
  • Fraternal: +0.6
    The way we grow up is also an important factor
74
Q

Weschler scales

A

Scales standardized to produce an intelligence quotient for every individual. IQ

75
Q

Flynn effect

A

The observation that raw IQ scores have been on the rise since 1932

76
Q

What are the 4 stages that Piaget proposed of cognitive development in children

A
  • Sensorimotor stage( until 2nd birthday)
  • Preoperational stage (2-7 years)
  • Concrete operational stage (7-12 years)
  • Formal operational stage( after 12 years)
77
Q

What is the sensorimotor stage?

A

until 2nd birthday. Child realizes

Object permanence: objects continue to exist even when you don’t see them anymore

78
Q

Preoperational stage

A
  • 2-7 years

- Egocentrism, Seriation, Reversible relationships, Conservation( ex: fluid conservation)

79
Q

Concrete operational stage

A
  • 7 to 12 years old

- struggles with abstract thinking and reasoning

80
Q

Formal operational stage

A

Can understand more theorical world (book)

81
Q

Confirmation bias

A

Tendency to seek out information that supports our hypothesis

82
Q

Availability heuristic

A

Tendency to make decisions based on the information that is most quickly available to us.

83
Q

Representativeness heuristic

A

Tendency to assume that what we are seeing is representative of the larger category we have on our minds.
