Longitudinal studies =get to investigate changes and how these
changes are influenced.
E.g.Freud study was a case
study carried out over 2 years
enabling the emotional
development of a young boy to
be investigated in great detail.
Samuel and Bryant selected a
sample of children aged from
5 years to 8.5 years old which
again allowed the researchers
to investigate developmental
changes in the children.
Enables
psychologists to
investigate different
areas of
development such as
cognitive in the
Samuel and Bryant
study and emotional
development in
Freud's study of Little
Hans.
Provides useful information about how we can better
understand how children learn and deal with
emotional difficulties and therefore improve the lives
of children.
E.g. the findings of the Samuel and Bryant study could be
used to identify and help children with cognitive
developmental difficulties and Bandura's findings have
implications about how adults should act in the presence
of children.
Tendency to generalise findings from often very limited
samples as it often looks forgeneral patterns of
development based on non representative samples.
Freud argued that all children experience psychosexual stages based on little
Hans' case study. Samuel and Bryant generalised their findings aboutcognitive
development from children in one town in the UK which ignores cultural
differences relating to howchildren may learn in other parts of the world.
Validity of measuring
children's behaviour and
thoughts, questions if
psychologists are actually
measuring what they are
attempting to measure
especially as children may
have qualiatively different
thoughts to adults.
E.g.Bandura's study
could be criticised for
interpreting the
children's behaviour
towards the Bobo doll
as aggression. Perhaps
the children interpreted
their own behaviour as
play.
Similarly we can question Freud's
interpretation of Hans' behaviour as the case
study is really Freud's interpretations of
Hans' father's interpretation of his son's own
phobia. Again this seriously reduces the
validity of the study.
