Q

What are the advantages of a structured interview? (2)

A
  1. Ensures that all children’s behaviors are observed in same context. 2. Allows controlled comparison of children’s behavior in different situations.

Q

What are the disadvantages of naturalistic observation? (2)

A
  1. Difficult to know which aspects of situation are most influential. 2. Limited value for studying infrequent behaviors.
17
Q

What is a microgenetic design?

A

A method of study in which the same participants are studied repeatedly over a short period of time.

18
Q

What are the features of a microgenetic design?

A

Children are observed intensively over a relatively short period of time while a change is occurring (like first step).

19
Q

What are the advantages of a microgenetic design? (2)

A
  1. Intensive observation of changes while they are occurring can clarify process of change. 2. Reveals individual change patterns over short periods in considerable detail.
20
Q

What are the disadvantages of a microgenetic design? (3)

A
  1. Does not provide information about typical patterns of change over long periods. 2. Does not yield data regarding change patterns over long periods. 3. Hard to find correct transition point.
21
Q

What are the disadvantages of a longitudinal design? (2)

A
  1. Difficult to keep all participants in study. 2. Repeatedly testing children can threaten external validity of study.
22
Q

What are the advantages of a longitudinal design? (2)

A
  1. Indicates the degree of stability of individual differences over long periods. 2. Reveals individual children’s patterns of change over long periods.
23
Q

What are the advantages of a cross-sectional design? (2)

A
  1. Yields useful data about differences among age groups. 2. Quick and easy to administer.
24
Q

What is an accelerated longitudinal design?

A

Study cross sections over time (combine both cross and longitudinal studies).

25
Q

What is the advantage of an accelerated longitudinal design?

A

Can tease apart age, time, and cohort effects.

26
Q

What is the disadvantage of an accelerated longitudinal design?

A

Requires more sophisticated statistical analysis.
