Reductionist Psychological Approaches

There are five approaches to psychology: biological, cognitive, behaviourist, psychodynamic and humanistic. The first three approaches are generally reductionist and the latter two are generally holistic.

The biological approach- reductionist

  • The biological approach looks at genetics, brain chemistry (hormones/neurotransmitters) and brain structure.
  • So this is biological reductionism because it focuses on constituent parts.
  • The aim attempts to look at cause and effect relationships.
  • It does not look at other factors such as social influence, environment or behaviourist influences.

The cognitive approach - reductionist

  • The cognitive approach is also reductionist.
  • This approach looks at cognition as being like a computer.
    • A computer takes in information (input), processes the information, then generates an output.

Reductionism

  • The cognitive approach is similar: humans take in sensory information, the brain processes the information, then it generates a response.
    • This is referred to as machine reductionism.
  • This is reductionist because it does not take into account how humans differ from computers.
    • For example, computers do not forget, whereas humans do.

The behaviourist approach

  • The final reductionist approach is the behaviourist one.

  • There are two types of conditioning:
    • Classical.
    • Operant.
  • Both involved stimulus-response.
  • This type of reductionism does not take into account any other influences such as biological or genetic factors.

Holistic Psychological Approaches

There are five approaches to psychology: biological, cognitive, behaviourist, psychodynamic and humanistic. The first three approaches are generally reductionist and the latter two are generally holistic.

The psychodynamic approach - Freud

  • The first holistic approach, generally speaking, is the psychodynamic approach.
  • Freud developed his theory of personality on three competing aspects:
    • The id.
    • The ego.
    • The superego.
  • He believed that personality and behaviour were the results of the interaction between the three.

Psychodynamic approach - holistic

  • Because the psychodynamic approach considers the conscious, unconscious and childhood events, which are multiple factors, it is a holistic approach.
  • As a result, the psychodynamic approach is not as scientific because it is difficult to test the various parts.

The humanist approach

  • Finally, humanism is the other holistic approach.
  • Humanistic psychologists examine the individual as a whole.
  • They believe that breaking down human behaviour into basic parts is too reductionist.

The humanist approach cont.

  • They agree with looking at the interactions of all of a person’s experiences and their feelings to explain behaviour.
  • The approach is more qualitative and subjective because it tends to use self-reporting techniques. This looks at the whole individual, not basic parts.
