Research methods A03 Flashcards
What is a strength of a lab experiment - Point (c.a.e)
Researchers can be confident when establishing cause and effect relationship between changes in the IV and observed differences in the DV
Explanation for (c.a.e)
By keeping variables outside the IV and DV consistent.. (c.a.e point)
What is a strength of a lab experiment (i.v)
high internal validity
What is a strength of a lab experiment - Point (e.r)
easily replicated because of standardised procedures
What is a limitation of lab studies - Point (e.v)
can lack ecological validity
Explanation for (e.v)
Findings from a lab study can’t be applied to real - world situations
What is a limitation of lab studies - Point (d.r.t)
tasks often don’t reflect tasks performed in the real world
What is a limitation of lab studies - Point (a.o.s)
Participants are aware they are in a study
Explanation for (a.o.s)
so they might alter their behaviours due to demand characteristics
What is a strength of a field experiment - Point (h.e.v)
High ecological validity
Evidence for (h.e.v)
Participants should behave naturally in their normal environment
Explanation for (h.e.v)
Behaviours observed in the field experiment can be applied to other naturalistic settings
What is a strength of field experiment - Point (m.r)
Closer to the type of activities the participant usually carries out
What is a strength of field experiment - Point (d.c)
There are no demand characteristics
Explanation for (d.c)
They are unaware they are in a experiment
What is a limitation of field experiments - Point (l.o.c)
There is a lack of control
Explanation for (l.o.c)
Possible extraneous variables could be influencing the measurements of the dependent variable
What is a limitation of field experiment - Point (r.i.v)
There is reduced internal validity
Evidence for (r.i.v)
It is either very difficult or impossible to randomly assign participants to separate conditions
What is a strength of a natural experiment - Point (o.f.r)
Allows research in areas that could not happen in controlled experiments either due to ethical or cost reasons
What is a strength of a natural experiment - Point (e.v)
High in external validity
Explanation for a natural experiment (e.v)
They are examples of real behaviour occurring in the real world free of demand characteristics
What is a limitation of a natural experiment - Point (c.c.e.v)
Extraneous variables cant be controlled
Explanation for (c.c.e.v)
The events have already or will happen and the researcher has no influence so the researcher shouldn’t claim they have found a cause and effect relationship
What is a limitation of a natural experiment- Point (r)
The studies cant be replicated
explanation for limitation of a natural experiment (r)
The events are often very rare so cant be replicated and therefore tested for reliability.
What is a strength of Quasi experiments - Point (o.w)
Quasi experiments are the only way to experimentally study factors that are pre existing characteristics of participants
What is a limitation of Quasi experiments - Point (c.f)
factors relating to the levels of IV cannot be controlled these change systematically and alter the measurement of the dependent variables (confounding variables)
