Q

What was the state of psychological study during the 1800s?

A

ideas about the mind are rooted in the belief that it is not possible to study the mind&raquo_space; the mind cannot study itself, the properties of the mind cannot be measured

Q

What is ANALYTIC INTROSPECTION?

A

Q

Describe Ebbinghaus’ concept of SAVINGS.

A

a measure used to determine the magnitude of memory left from initial learning; higher savings = greater memory

Q

What is a consequence of the behaviourist view that only observable behaviour provides data?

Q

What elements of analytic introspection was Watson dissatisfied with?

A
  1. it produced extremely variable results from person to person
  2. results were difficult to verify bc they were interpreted in terms of invisible mental processes
26
Q

What were Watson’s 2 key points in presenting behaviourism as an alternative form of study?

A
  1. Rejection of introspection as a method
  2. Observable behaviour, not consciousness, is the main topic of study
27
Q

What is CLASSICAL CONDITIONING?

A

pairing one stimulus with another, previously neutral, stimulus, causing changes in the responses to the neutral stimulus

28
Q

How did Watson use classical conditioning as support for the study of behaviourism?

A

argued that behaviour can be analyzed without any reference to the mind

what is going on inside the mind of a dog hearing a bell, or Little Albert hearing a loud noise when a rat is presented, is irrelevant > we only care about how pairing one stimulus with another affects behaviour

29
Q

What is OPERANT CONDITIONING and who was its founder?

A

focuses on how behaviour is strengthened by presentation of positive reinforcements or removal of negative reinforcements

BF Skinner

30
Q

Who was Edward Chace Tolman and what was his focus of study?

A

measured behaviour, but used behaviour to infer mental processes, making him one of the earliest cognitive psychologists

31
Q

What is a COGNITIVE MAP?

A

concept developed by Tolman

a mental representation of one’s physical environment

32
Q

What about the concept of a cognitive map placed Tolman outside of mainstream behaviourism?

A

the use of the word “cognitive” and the idea that something other than stimulus-response connections might be occurring in an animal’s mind

33
Q

What position did BF Skinner take about language development in his 1957 book Verbal Behaviour?

A

argued that children learn speech through operant conditioning, imitating speech they hear, repeating correct speech bc it is rewarded

34
Q

What were Noam Chomsky’s arguments against Skinner’s language development theories?

A
  1. children say many sentences that are never rewarded by parents
  2. during language development, children go through a stage of incorrect grammar use which may never have been reinforced
35
Q

What were the foundations of Chomsky’s theory of language development?

A
  1. language develops as determined by an inborn biological program that holds across many cultures
  2. language is a product of the way the mind is constructed
  3. language and other complex processes should be understood not only by measurable behaviour but also by what this behaviour tells us about how the mind works
36
Q

What is the COGNITIVE REVOLUTION?

A

a shift in psychology, beginning in the 1950s, from the behaviourist approach to one in which the main goal was to explain behaviour in terms of the mind

37
Q

What was one of the key outcomes of the cognitive revolution?

A

introduction of the information processing approach to studying the mind

38
Q

What is a PARADIGM?

A

a system of ideas that dominates science at a particular time

39
Q

What is a PARADIGM SHIFT?

A

a fundamental change in approach or underlying assumptions

40
Q

What is a SCIENTIFIC REVOLUTION?

A

a shift from one scientific paradigm to another

41
Q

What were the pros and cons of the behaviourist approach to psychological study?

A

PROS: included development of psychological “behavioural therapies” which are still in use

CONS: did not allow any consideration for the mind’s role in creating behaviour

42
Q

How did the introduction of the first digital computers influence the development of information processing theory?

A

psychologists resonate with the processing flow of a computer, which occurs in stages:
1. Input is received by an “input processor”
2. Then storied in a “memory unit”
3. Processed by an “arithmetic unit” which creates output

43
Q

What is the INFORMATION PROCESSING APPROACH?

A

the mind is described as processing information through a sequence of stages

44
Q

Describe Donald Broadbent’s experiment involving filtering information.

A

one message is presented auditorily through one ear, and a different message is presented through the other ear
it was found that people could hear the sounds of the unattended message, but were unaware of its contents

45
Q

Describe Broadbent’s flow diagram of the mind regarding attention.

A

Input is presented > the “filter” of the mind lets through the attended message and filters out the unattended message > the “detector” records the information that gets through the filter

46
Q

What was so valuable about Broadbent’s experiment for further study?

A

provided a way to analyze the operation of the mind in terms of a sequence of processing stages, which could be further tested in other experiments

47
Q

Where was the term “artificial intelligence” first used, and who was the founder of this event?

A

The Summer Research Project on Artificial Intelligence conference in 1956, founded by John McCarthy

48
Q

What is ARTIFICIAL INTELLIGENCE?

A

the ability of a computer to perform tasks usually associated with human intelligence

49
Q

Who created the first AI program and what was its function?

A

Herb Simon and Alan Newell created a program called “logic theorist” that could create proofs for problems in logic using humanlike reasoning processes

50
Q

George Miller presented the idea that there are limits to a human’s ability to ___________________ ___________________________. How many items can a human typically process at once?

A

process information; 7 (phone number)

51
Q

When was the first Cognitive Psychology textbook published, and by whom?

A

1967 by Ulrich Neisser

52
Q

What was the main focus of Neisser’s textbook?

A

Vision and hearing
How is information taken in by vision and held in memory for short periods of time
How do people search for visual information and use it to see simple patterns

53
Q

What key topics were missing from Neisser’s textbook, and are the central topics in cognitive study now?

A
  1. higher mental processes (thinking, problem solving, long term remembering)
  2. physiology
54
Q

What are the 3 stages of memory flow according to Richard Atkinson and Richard Shiffrin?

A

Sensory Memory > incoming information is held for a fraction of a second, then is passed to STM
Short Term Memory > limited capacity, holds info for seconds
Long Term Memory > high capacity where some STM is transferred for a long time, and can be retrieved

55
Q

What subdivisions did Endel Tulving propose make up long-term memory?

A

Episodic memory > events in your life
Semantic memory > facts
Procedural memory > physical actions

56
Q

What is NEUROPSYCHOLOGY?

A

the study of the behaviour of people with brain damage

57
Q

What is ELECTROPHYSIOLOGY?

A

measuring the electrical responses of the nervous system, making it possible to listen to the activity of single neurons

58
Q

What is BRAIN IMAGING?

A

techniques such as fMRI that result in images of the brain that represent brain activity; in cognitive psych, activity is measured in response to specific cognitive tasks

59
Q

When was Positron Emission Tomography (PET) introduced and what were the pros and cons?

A

1976
makes it possible to see which area of the brain are activated during cognitive activity

it is expensive and involved radioactive tracers injected into the bloodstream

60
Q

What are some important features of contemporary cognitive psychology?

A
  1. flow diagrams are more sophisticated; include more consideration of higher mental processes and physiological research
  2. research is taken out of the lab; lots of “real word” studies
  3. humans are not “blank slates” that just accept and store information > experiments demonstrate the important of knowledge for cognition
61
Q

What did Stephen Palmer demonstrate regarding contextual knowledge?

A

people used their knowledge of objects that were likely to be found in a given environment to help them perceive images faster than images of items that do not contextually belong
