approaches

• biological approach


  +reduces humans to a set of mechanisms and physical structures that are clearly essential and important e.g. genes

  -it fails to account for consciousness and the influence of the environment and behaviour
• cognitive approach 


  + focuses on thinking, our feelings, beliefs, attitudes and expectations and the effect they have on behaviour

  -ignores subjective experiences people have
• biological 


  explains behaviour in terms of physical causes in our brains and bodies
• cognitive 


  employs the computer metaphor to explain how our minds work, like computers we process information
