Q

Naturalistic Observations

A

-Observers record observational behaivour

-Requires operational definiton

-Observers must be trained to consistently code their observations

28
Q

Issues with measuring overt behaivour (2)

A
  1. Participants can change their behaivour when being observed
  2. Demand characteristics
29
Q

Social Desirability Bias

A

Aspects of observational setting that make people behave as they think they should

30
Q

Types of research (4)

A

-Descriptive

-Correlational

-Survey

-Observational

31
Q

What is Naturalistic Observation

A

Observing people/animals in their natural environment

32
Q

two advantages of naturalistic observations:

A
  1. Provides rich description of behaviour
  2. Can avoid demand characteristics (they do not know they are being watched)
33
Q

Two limits to naturalistic observations

A
  1. Can not inform a Pearson that they are being observed
  2. Requires long period of observation to get a single measure of a desired behaviour
34
Q

Survey research involves:

A

Asking participants questions through interviews or questionnaires

35
Q

Population

A

the entire set of individuals about who we wish to draw a conclusion

36
Q

Sample

A

a subset of individuals drawn from a population

37
Q

A representative sample _____

A

reflects important ccharesteristcs of the population

38
Q

To have a representative sample you have to use ________

A

Random Sampling

39
Q

Surveys like descriptive research can not be used to _______-

A

draw conclusions about population

40
Q

psychological tests

A

specialized tests designed by psychologists to measure particular variables

41
Q

3 psychological test

A
  1. Neuropsychological
  2. Personality
  3. Intelligence
42
Q

Correlational Research 3 aspects:

A
  1. Measure X
  2. Measure Y
  3. See if X is related to Y
43
Q

Correlation does not equal _______

A

causation

44
Q

You can only make casual inference if you have a ______

A

experiment

45
Q

Biderecitonality problem

A

Does X cause Y or does Y cause X

46
Q

Third variable problem

A

two variables only have a correlation to each other because they are confounded by a third variable they are causally related to

47
Q

r describes

A

relation between two variables

48
Q

explain r

A

if positive then positive relation, the higher the number (take the absolute value) the stronger the relationship

49
Q

r = 0 means

A

there is no relationship

50
Q

3 advantages of correlational research

A
  1. shows strength or present relationships
  2. can be used to make predesictionsd about variables
  3. identifies ‘real-world’ associations
51
Q

2 disadvantages of correlational research

A
  1. can not assume cause-effect relationship
  2. Third-variable problem
52
Q

3 steps or experimental research:

A
  1. Manipulation of one variable
  2. Measure changes in another variable

3.Controlling variables

53
Q

Variable:

A

A property whose value can change across individuals and over time

54
Q

Independent Variable:

A

The variable that is manipulated in an experiment

55
Q

Dependant Variable:

A

The variable that is measured in a study

56
Q

Exxpiremental variation:

A

Researchers systematically varying what participants are exposed to (Independent variable) using random assignment to minimize bias

57
Q

Comparative Baseline:

A

The experimental group receives the treatment, while the control group experiences all other aspects equally except the treatment

58
Q

Isolating Effects:

A

Comparing experimental and control groups allows researcher to isolate the effects of IV, establishing a baseline for what naturally occurs (control) versus what changes with the treatment (experimental)

59
Q

Two types of research expirements:

A

-Between Groups/Between Subjects

-Repeated measures (within subjects)

60
Q

Between Groups/Between Subjects design

A

each group in the experiment is composed of a different set of participants (first BSR experiment)

61
Q

Repeated measures (within subjects design)

A

Each participant is exposed to all the conditions of an independent variable (second BSR experiment)

62
Q

Purpose of ethical standards

A

to protect the welfare off both humans and animals in psychological research

63
Q

5 points of ethics

A
  1. Psychologist must protect and promote the welfare of participants

What does the Animal Ethics slide have?

A

The dates on events related to animal ethics

70
Q

A
  1. Must be trained in research methods, the care of laboratory animals
  2. Appropriate anesthesia and pain management

71
Q

Who contributed to the Three R’s

A

Russel and Burch

72
Q

What do the three R’s serves as

A

Guiding principles for ethical testing

73
Q

What are the 3 R’s

A
  1. Replacement
  2. Reduction
  3. Refinement
74
Q

Replacement

A

methods which avoid or replace the use of animals in research

75
Q

Reduction

A

use of methods that enable researchers to obtain comparable levels of information from fewer animals, or to obtain more information from the same number of animals.

76
Q

Refinement

A

use of methods that alleviate or minimize potential pain, suffering or distress, and enhance animal welfare for the animals used.
