evaluation

• • one strength of the interference theory is that it has supporting evidence.
  • for example McDonald and McGeoch investigated whether recall depended on interfering material. They found that retroactive interference was greater with similar words.
  • This means that the interference theory is valid in explaining how things are forgotten.
• • one limitation of the interference theory is that the supporting evidence lacks mundane realism.
  • This is because there is meaningless stimuli such as the participants remembering a list of words which is maade up and has no correlation to real life.
  • This means that interference may not be a valid explanation for forgetting.
