support for cdf theory

• godden and baddeley 1975
• tested the effect of external cues on retrieval
• made pps learn word lists on land and underwater
• the recall of the word lists were then either tested in the same location or opposite contexts where they initially learned the list
• found that pps recall was better when they were tested in the same context as where they learned the lists
• this study provided evidence for external cues to help retrieval
• A03 limitations for cdf theory

  studies may lack ecological validity, we don't often learn things underwater
• A03 limitations for cdf theory

  cue dependent forgetting is less relevant to explaining how we recall and forget procedural memories
