Q

To completely understand a behavior, researchers strive to do what?

Q

Basic research

A

Research conducted simply for the knowledge it produces

20
Q

What is the purpose of basic research?

A

To obtain knowledge

21
Q

What is the purpose of applied research?

A

To solve an existing problem

22
Q

What is one specific study in light of a behavior?

A

A “snapshot” or small portion, representing a very limited and simplified view and contributing minutely to the goals of understanding a behavior

23
Q

Hypothesis

A

A formally stated expectation about how a behavior operates

24
Q

Casual hypothesis

A

Tentatively identifies a particular cause for, or influence on, a behavior

25
Descriptive hypothesis
Tentatively describes a behavior in terms of its characteristics or the situation in which it occurs, and allows us to predict when it occurs. NOT causes
26
Main difference between casual and descriptive hypotheses?
Casual postulates an influence, descriptive postulates characteristics
27
Testable
It is possible to devise a test
28
Falsifiable
The test can potentially show that the hypothesis is incorrect
29
Precise
Clearly defined
30
Rational
Logically fits with what is already known
31
Parsimonious
As simple as possible
32
What characteristics should a scientific hypothesis have?
Falsifiable, testable, precise, rational, and parsimonious
33
Theory
An integrated set of proposals that defines, explains, organizes, and interrelates knowledge about many behaviors
34
Two major functions of theories?
Organize findings and guide research
35
What is a theory?
An organized body of research that describes and explains a wide range of behaviors
36
Model
A description that, by analogy, explains the process underlying particular behaviors. More specific and concrete than a theory
37
Prediction
A specific statement about how we will see the behavior manifested in the research situation, describing results we expect to see
38
Four flaws in evidence
Some behaviors cannot be studied in a completely empirical, objective, systematic, and controlled way, decisions made in designing a study, technical limitations that produce misleading info, and the results of one study may be biased or a fluke
39
What does the design of eh study determine?
The snapshot of the behavior and the evidence for the hypothesis
40
Disconfirmation
Evidence that the hypothesis is false
41
Confirmation
Findings are consistent with the hypothesis, but does not make the hypothesis true
42
Where does the best evidence come from?
Disconfirming competing hypotheses and confirming your own
43
What do we do when we confirm a hypothesis?
Merely more confidant that it is true, it can never be proven
44
What is our confidence in any hypothesis based on?
The quantity and quality of evidence
45
Replication
Repeatedly conducting studies that test and confirm a hypothesis
46
Literal replication
Duplicate precisely the specific design and results of a previous study, eliminates "chance factors"
47
Conceptual replication
Provides additional confirmation while measuring the behavior in a different way, with different types of participants, or with a different design
