Strengths and Weaknesses of
Psychological Approaches
Psychodynamic
Approach
The psychodynamic approach enables the researcher
to gain insight into internal processes that were not
deemed suitable for study by behaviourists
psychologist.
Data collection is subjective rather than objective
and the therapist/researcher could plant ideas in
the mind of the participant,
The emphasis on the individual
inevitably leads to small sample size,
which means the findings cannot be
generalised.
Findings cannot be subjected to scientific
scrutiny.
The interview method enables the
collection of rich, in depth data.
The focus on the individual enables the
researcher to gain an in-depth understanding of
that individual.
Physiological
Perspective
The physiological approach
enables us to understand the
biological basis of human
behaviour.
Recent advances in both genetic
research and the application of
modern technology (MRI scans)
have greatly extended our
understanding of how biology
shapes behaviour.
The Physiological approach is
generally scientific and uses rigorous
and objective data collection
techniques.
Physioloical
research is ofter
correlational
which means
that cause and
effect may not
be identified.
Physiological psychologists are sometimes criticised for
determinism because they attribute behaviours to innate
physiological factors rather than to choice/free will.
Physiological psychologists
are sometimes criticised
for reductionist because
they reduce behaviours to
specific physical processes.
Social
Approach
Social psychologists have, in the past, sometimes broken
ethical guidelines and risked causing psychological harm
to participants. However, present-day social psychologists
make every effort to maintain high ethical standards.
Social approach studies
are often high in
ecological validity because
they often study people in
real-life situations.
The social approach enables us to
gain an understanding of the
influence of situations and other
peoples reactions to our
behaviour.
The social approach enables us to
understand social cognition - in other words,
what we think and feel about our own
behaviour.
With the social approach it can be
difficult to devise a reliable, valid
measure of human interactions.
Social psychologists do not always
have control of variables as they
study human interactions (using
observations or field experiments)
and these cannot be controlled in
the same way as, for example,
cognitive tasks in laboratory
experiments.
Individual Differences
Approach
The individual differences
approach sometimes deals with
very small sample sizes, which
means the results are not
generalisable.
The individual differences
approach helps us understanding
issues of mental health
psychological dysfunction.
The individual differences
approach enables us to
determine which aspects of
human behaviour are general
to the species and which are
shaped by individual factors.
The individual differences
approach often uses a detailed
case-study approach that
provided rich data.
Individual differences psychologcy may lead to
labelling if individuals are categorised as
different from the norm, with labels such as
'dysfunctional' or of 'low intelligence' or
neurotic'.
Psychometric tests attempt to ensure
traits such as intelligence and
personality that may not really be
amenable to measurement,
Developmental Approach
A case-study approach is
sometimes used, which enables
the collection of rich, longitudinal
data.
The developmental approach
enables us to understand how
cognition and behaviour change
across a lifespan.
The developmental approach
often uses well-controlled
studies as experiments to
investigate cognitive
development.
Much developmental researcg focuses on
children and this raises withical issues,
particilaurly in the case of very young
children who cannot give informed
consent or understand debriefing.
There can be practical difficulties involved in
working with children. It can be difficult to
ensure that they understand instructions,
they can have difficulty concentrating on
tasks and they ay be more subject to
suggestion than adults.
Developmental psychology tends to focus
on developmental norms and may
underestimate the ole of individual
differences.
Cognitive Approach
The cognitive approach frequently deals
with inner rocesses that are not
observable. This means that researchers
are often dependant on self0report for
their data and such data are not always
seen as objective.
The cognitive approach helps us theorise about
the way in which mental processes occur it is
not usually directed at answering questions
about the physical processes that underlie
processes, such as how memories are stored in
the brain.
The cognitive approach applies rigorously,
scientific approaches to the study of mental
processes and how they shape behaviour.
Cognitive approaches studies often use
the experimental methods which can
limit the ecological validity of the findings.
The cognitive approach enables us to gain
insights into the inner processes that are
not observable behaviours.
Cognitive studies often use
the experimental method,
which enables identification
of causes and specific
behaviours.
Behaviourist
Perspective
The behaviourist perspective is limited
to observable behaviours and therefore
do not provide insight into internal
mental process.
The behaviourist perspective is
determinist. If all behaviour is
conditioned, there is no room for
free will in explaining human
behaviour.
The behaviourist perspective is
reductionist. This means that it
reduces the complexity of human
behaviour to a set of stimulus
responses relationships.
The behaviourist perspective applies the
principles of the scientific method to the
study of human behaviour,
The behaviourist
perspective provides a
useful framework for
the treatments of a
range of Psychological
disorders.
The behaviourist perspective
provides valuable insights into
the effects and experience on
cognition including, the
developments of dysfunctional
cognitions such as phobias.
