Support for Coding : Baddeley (1966)

• Who conducted the investigation on coding in memory?

  Baddeley
• What types of memory did Baddeley investigate?

  Short term and long term memory
• How did Baddeley test short term memory in his experiment?

  Participants recalled words immediately after learning
• How did Baddeley test long term memory in his experiment?

  Participants recalled words after 20 minutes
• How did Baddeley divide the participants in his study?

  Into four groups with different word sets
• What type of words did the first group receive?

  Words that sounded similar
• What type of words did the second group receive?

  Words that didn't sound similar
• What type of words did the third group receive?

  Words with similar meanings
• What type of words did the fourth group receive?

  Words with different meanings
• Why should the group with similar sounding words find recalling difficult?

  They may confuse the words with each other
• Why should the group with dissimilar sounding words find recalling easier?

  They are less likely to confuse the words
• Why would recalling words with similar meanings be harder?

  It is easier to get confused between them
• Why would recalling words with different meanings be easier?

  They are less likely to be confused
• What did Baddeley find about recalling similar sounding words?

  Participants recalled the fewest words
• What did Baddeley find about recalling dissimilar sounding words?

  Participants recalled the most words
• What evidence did Baddeley provide for acoustic coding?

  Similar sounding words recalled the least
• What evidence did Baddeley provide for semantic coding?

  Different meaning words recalled the most
• What was the recall performance of the group with similar meaning words?

  They recalled the least number of words
