    • AO1
      • suggests the information in the LTM may become confused or combined with other information during encoding, therefore distorting or disrupting memories
      • Proactive
        • old memories disrupt new memories
      • Retroactive
        • new memories disrupt old memories
      • both are most likely to occur if both memories are similiar e.g. old and new telephone numbers or languages
    • AO2
      • POSITIVE
        • POSTMAN 1960
          • recall of those in the control without interference was better than those with interference
        • recent 'real life' studies have supported interference
        • ANDERSON 2000
          • interference plays a part in forgetting but we dont know how much
        • MCGEOCH 1932
          • tested the ideas in lab experiments
      • NEGATIVE
        • MCGEOCH 1932 low eco validity, high demand characteristics and unrepresented, therefore ungeneralisable
        • theory tells little of cognitive processes involved
        • Majority of research in lab experiments=low eco validity and ungeneralisable
