• P- A strength of the

  behaviourist approach

  is that it is highly

  scientific.
• E- This is because it

  relies upon controlled

  experimental

  methods and research

  findings, such as

  Pavlov’s dogs and

  Skinner’s rats studies.
• E- These studies use

  specific conditions

  with standardised

  procedures and

  variables that can be

  manipulated and the

  outcomes can be

  measures in an

  objective way.
• L- This is a strength

  because it allows

  strict control of

  variables, which

  means that it is easier

  to establish a cause

  and effect

  relationship.

  Therefore, this theory

  has high internal

  validity.
