Q

What did the logical positivism movement entail

A

They said that meaningful claims are either empirical or logical in nature, logical claims are verifiable by looking at their form (e.g. logic and maths) and help represent the world, empirical claims are about the world and can be verified by observation, claims that are not verifiable are meaningless

Q

What are 4 problems with logical positivism and explain them

A
  1. Separation of theory and observation: many concepts are open concepts which can change meaning over time and many observations are already theory-laden
  2. Underdetermination of theory by data: it is assumed that one observation can only lead to one theory, but in practice this is usually not at all the case. To chose between theories scientists use other criteria, which are theoretical themselves
  3. Induction: causality and general statements are excluded because neither are verifiable
  4. Unobservable entities: there are many entities that we cannot observe (e.g. bc they are very small) but we know of their existence. Does that mean they are not part of science? And what if we create better instruments so that we can see them, do they then become part of science? —> inconsistency

Q

How are theories constructed according to Popper and what happens to them

A

Theories emerge from the mind and then predictions are derived from it, these are tested on the basis of observation and if the observation proves the theory wrong, the theory is refuted

Q

Explain the hypothetico-deductive model

A

Start with a theory, deduce predictions from theory, test predictions, if predictions don’t come true; falsify the theory —> if they do come true; corroboration (not verification)

Q

What are 5 problems with Popper and falsification

A
  1. theories are at best ‘not yet refuted’
  2. No knowledge on how to build theories
  3. Hard falsification is difficult (Duhem-Quine Problem)
  4. Very counterintuitive for scientists to want to falsify their own theories
  5. Popper said he had a normative theory, but it does not describe examples of what we consider scientific success if we look at history

Q

What are the 5 stages of science according to Kuhn and explain them

A
  1. Pre-science: no consensus within field, little progress, lack of specialized community
  2. Normal science: no novelties, not very experimental, expand current paradigm
  3. Anomalies and crisis: new findings make current paradigm unfit
  4. Revolution: shift from degenerative to progressive research model
  5. Normal science 2: new stage of normal science after a paradigm shift

Q

What are the 4 ways of gathering knowledge according to Pierce

A
  1. Method of tenacity - assumptions and beliefs people hold because they have been around for a long time
  2. Method of authority - opinions formed on the basis of consulting experts
  3. A priori method - using personal reason and logic to reach conclusions; deductive reasoning but also intuitive knowledge
  4. Scientific method

What 3 types of situations were tests most used for
- authenticity tests - qualifying tests - diagnostic tests
28
What were 2 criteria to distinguish good tests from bad tests
Reliability and validity

- Industrial psychology, - human relations movement - human resource management
30
Clinical psychology
branch of psychology applying psychological knowledge to the assessment and treatment of mental disorders
31
Shell shock
anxiety response on battlefield that prevents soldiers from functioning properly; was one of the first topics addressed by applied psychology
32

Authenticity test
test to determine whether a person is who he/she pretends to be and to ascertain guilt or innocence
36
Qualifying test
Test to find the best person for a task
37
diagnostic tests
Tests to determine which condition a person has
38
Reliability
in test research, the degree to which the outcome of a test is the same if the test is repeated under unchanged circumstances or if an equivalent test is used
39
Validity
in test research, the degree to which a test measures what it claims to measure; determined by correlating the test results with an external criterion
40
Implicit personality theory
mixture of stereotypes and individuating information about the associations of personal characteristics that people use to make predictions about how others will behave in social relations
41
standardized psychological test
test that psychologists have examined for reliability and validity, for which they have information about the expected performance, and which is administered in a uniform way
42
IQ test
test which is supposed to measure the intelligence of a person; focuses on learning potential; results correlate with school performance and suitability for intellectually demanding occupations
43
Achievement test
standardised test which measures the knowledge of a particular topic or set of topics
44
Face validity
estimating the validity of a test by estimating to what extent the items of the test agree with one’s own beliefs; is not evidence-based
45
Industrial psychology (who?)
first theory about how work should be organised; strongly influenced by Taylor’s scientific management: employees were the hands of the company that would accept any work if remunerated enough; tasks had to be made simple so that everyone could do them without much practice
46
Human relations movement
second main theory of how work should be organised; stressed the humanity of the employees and the importance of social relations
47
Human resource management
third main theory of how work should be organised; stressed the desire for self-actualisation in employees; employees will perform best if given autonomy and authority
48
Correspondence theory of truth
a statement is true when it corresponds with reality.
49
Skepticism
philosophical view that does not deny the existence of a physical reality, but denies that humans can have reliable knowledge of it
50
Demarcation
setting and marking the boundaries of a concept
51
Philosophy of science
branch of philosophy that studies the foundations of scientific research, to better understand the position of scientific research relative to other forms of information acquisition and generation
52
Falsificationism
View within the philosophy of science that statements are scientific only if they can be falsified empirically
53
Ad hoc modifications
modifications to a theory that according to Popper make the theory less falsifiable; decrease the scientific value of the theory
54
Paradigm
notion introduced by Kuhn to refer to the fact that scientists share a set of common views of what the discipline is about and how problems must be investigated
55
Degenerative research programme
a paradigm that does not allow researchers to make new predictions and that requires an increasing number of ad hoc modifications to account for the empirical findings
56
Progressive research programme
a paradigm that allows researchers to make new, hitherto unexpected predictions that can be tested empirically
57
Realism
view within philosophy that human knowledge tries to reveal real things in the world; the truth of knowledge is determined by the correspondence of the knowledge with the real world
58
Idealism
view within philosophy that human knowledge is a construction of the mind and does not necessarily correspond to an outside world; the truth of knowledge depends on coherence with the rest of the knowledge in the social group
59
Postmodernist
in the philosophy of science, someone who questions the special status of science and sees scientific explanations as stories told by a particular group of scientists
60
Social construction
notion used by postmodernists to indicate that scientific knowledge is not objective knowledge discovering the workings of an external reality, but a story told by a particular scientific community on the basis of its language and culture
61
What is pragmatism and who coined the term
view within philosophy that human knowledge is information about how to cope with the world; the truth of knowledge depends on the success one has in engaging with the world, on what works; truth of a question or theory is only relevant if it makes a practical difference —> Pierce
62
Science wars
notion used by the postmodernists to refer to their attacks against the special status of science and their unmasking of scientific knowledge as a social construction
63
Observation sentences
Sentences that directly describe reality
64
Correspondence rules
They are rules that link the observational sentences to theoretical vocabulary (e.g. observational sentence = a person answered yes to the question if they have been very sad in the last two weeks, theoretical vocabulary = if a person answered yes to this and 5 other questions they are clinically depressed)
65
What are open concepts and who coined the term
Concepts of which the meaning can change over time, Arthur Pap
66
Does falsificationism build on the principles of rationalism or empiricism
Rationalism
67
What is incommensurability
The fact that Kuhn says that two paradigms cannot be compared to each other because they are so vastly different in the language and concepts that they use
68
What are auxiliary assumptions
Body of beliefs that help the theory
69
In reaction to the auxiliary assumptions you can either have negative or positive heuristics, what does this mean
Negative: you cannot revisit the core Positive: some adjustments to protect the hard core are okay
70
What was bacons relevant contribution to these subjects
He was one of the first to promote observation and experimentation to acquire knowledge, instead of just relying on tradition and authority
71
What was Whewell’s most important contribution
He also acknowledged that hypotheses were possibly wrong conjectures
72
What were the 3 basic conditions for tests according to Hanson
1. A test contains the condition of intent: tests are planned, arranged and given by someone with a purpose in mind; they are never random events. 2. A test is not administered to collect information about performance on the test itself, but as an indication of some other condition: for instance, uroscopy was not meant to collect information about the urine, but to make statements about possible illnesses in the person. 3. A test involves a difference in status between the test giver and the test taker: the test giver draws conclusions on the basis of the test which the test taker has to undergo.
73
What are 5 characteristics of science (other demarcations criteria)
1. Systematicity and cumulativeness of knowledge 2. Use of well-defined methods 3. Clarity (= findings should be stated in a way that they’re always interpreted the same) 4. Prediction 5. Knowledge is revisable
