• What was the aim?

  To see if there is a difference in LTM between acoustically similar words and semantically similar words
• What was the procedure?

  Lab experiment designed to test recall of acoustically and semantically similar words

  Conducted 3 different experiments
• In experiment 3, how many lists of 10 words were used?

  4
• What type of words were in List A?

  Acoustically similar

  (man, cab, can, mad etc)
• What words were in list B (a control group for list A)

  acoustically dissimilar words (pit, few, cow etc)
• What words were in list C?

  semantically similar (great, larger, big etc)
• What words were in list D (a control group for list C)

  semantically dissimilar (good, thin, hot etc)
• What was the sample?

  72 ppts- men and women from Applied Psych Research Unit
• What were the ppts asked to do after the presentation of words?

  Complete 6 tasks involving memory for digits

  Then asked to recall to word lists in 1 min by writing down sequence in correct order
• What were the results for acoustically similar and dissimilar words

  Recall of acoustically similar words was worse
• What were the results for semantically similar and dissimilar words?

  Recall of semantically similar was worse
• Give 1 strength of the study

  1.Reliability: did 3 experiments that all showed similar results- also standardised and controlled
• Give 2 weaknesses of the study

  1.Low ecological validity: tasks were not natural

  2.Reductionist: reduces memory down to how well the order of lists of 10 words can be recalls
