Q

What are some different types of psychological tests?

A

Personality tests (typically self-reported); intelligence tests (psychological tests); neuropsychological tests (diagnosis different neurological reaction)

26
Q

What are the different types of research?

A

Descriptive; Correlational; Experimental

27
Q

What does descriptive research focus on?

A

Seeks to explain how an individual behaves, especially in natural environments

28
Q

What is a type of descriptive research?

A

Naturalistic observation

29
Q

Observing people/animals in their natural environment is what type of descriptive research?

A

Naturalistic Observation

30
Q

What is an advantage of naturalistic observation?

A

Provides a rich description of behaviour; can avoid demand characteristics

31
Q

What are some limits of naturalistic observation?

A

Can’t inform a person that they are being observed + can’t ask them questions; requires long periods of observation to get a single measure of a desired behaviour (not efficient)

32
Q

What type of descriptive research asks participants questions through interviews or questionnaires?

A

Survey research

33
Q

Define a population

A

The entire set of individuals about whom we wish to draw a conclusion

34
Q

Define a sample

A

A subset of individuals drawn from a population

35
Q

What is a representative sample?

A

A sample that reflects the important characteristics of the population (sample matches/represents the population)

36
Q

What is random sampling?

A

Every member of the population has an equal probability of being chosen (completely random)

37
Q

What are some of the downfalls of surveys?

A

Can’t be used to draw conclusions about cause and effect; rely on participants self-reports; incorrect generalizations about populations

38
Q

What is variability?

A

How much measurements differ from one another

39
Q

What is the range?

A

Value of the largest measurement in a frequency distribution minus the smallest

40
Q

What is standard deviation?

A

Describes the average difference between the measurements in a frequency distribution and the mean of that distribution

41
Q

What direction does the tail of a graph with the collected data point when it is positively skewed?

A

Tail goes to the right

42
Q

What direction does the tail of a graph with the collected data point when it is negatively skewed?

A

Tail goes to the left

43
Q

What is skewed distributions?

A

When a frequency distribution is normal (the shape looks like a ghost)

44
Q

What is correlational research?

A

Looking for an association between two (or more) measured variables [Studies if there’s a relationship between x & y]

45
Q

Is correlation the same as causation?

A

NO -> Just because they’re related doesn’t mean that x causes y

46
Q

What does correlational research remind us?

A

That 2 variables may be related to one another only because they are both casually related to a third variable

47
Q

What is a correlation coefficient?

A

It describes the relationship between 2 variables

48
Q

What makes a positive correlation?

A

An increase in one variable relates to an increase in the other (ranges between 0 to 1)

49
Q

What makes a negative correlation?

A

An increase in one variable relates to a decrease in the other (ranges from -1 to 0)

50
Q

What makes a zero correlation?

A

There is no relationship (i.e. the 2 variables are not correlated with one another)

51
Q

What are some advantages of correlational research?

A
  1. Show the strength of present relationships
  2. Can be used to make predictions about variables
  3. Identifies ‘real-world’ associations
52
Q

What are some disadvantages of correlational research?

A
  1. Can’t assume cause-effect relationship exists
  2. Relationships may be due to a third unmeasured variable
53
Q

What are the 4 stages of experimental research?

A
  1. Manipulation of one variable
  2. Measuring changes in another variable
  3. While holding all other factors constant (control for other variables)
  4. Can manipulate/measure more than one variables
54
Q

What are the 4 stages of experimental research?

A
  1. Manipulation of one variable
  2. Measuring changes in another variable
  3. While holding all other factors constant (control for other variables)
  4. Can manipulate/measure more than one variable
55
Q

What are the 2 types of research designs?

A

Between groups and repeated measures

56
Q

How are ethical standards designed?

A

Designed to protect the welfare of both human and animal subjects in psychological research

57
Q

What are the 5 ethical standards that psychologists must adhere too?

A
  1. Protect and promote the welfare of participants
  2. Avoid doing harm to participants
  3. Not carry out any studies unless the probable benefit is proportionately greater than the risk
  4. Provide informed consent
  5. Ensure privacy and confidentiality
58
Q

What is refinement in relation to use of animals in testing?

A

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

59
Q

What is reduction in relation to the use of animals in testing?

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

60
Q

What is replacement in relation to use of animals in testing?

A

Methods which avoid or replace the use of animals in research
