SPERLINGS PROCEDURES

• What did Sperling's first study called?

  Sperling's 1960 study of iconic coding into sensory memory
• what was sperlings second study?

  Sperling's 2nd procedure ''the partial report'' - capacity
• what was Sperling's third procedure?

  Sperlings 3rd Procedure - duration
• what type of memory did Sperling study?

  sensory memory
• what was the aim of Sperling's first study?

  to investigate the coding? of the sensory memory
• What method did Sperling use in his first study?

  • Laboratory experiment
  • Participants flashed 3x4 grid for a fraction of a second
  • Participants were asked for immediate recall
• what were the results from Sperling's first study?

  on average, participants could recall 4.5 out of 12 letters
• what was the method for Sperling's 2nd procedure?

  • Sperling added a high, medium or low tone immediately after the letters were shown.
  • Participants had to recall the top, middle or bottom row.
• what were the results from Sperling's 2nd procedure?


  participants could remember 3.3 out of 4 letters on average
• what was the conclusion from sperling's 2nd procedure?

  they were better in the partial report, suggesting that they were reading the letters from an ''after image''

  THIS SHOWED ICONIC CODING
• What was the method of sperling's 3rd procedure?

  Sperling increased the decay from seeing the image and then hearing the tone
• what were the results from sperling's 3rd procedure?

  the recall decreased as the after image rapidly faded
• what was the conclusion for sperling's 3rd procedure?


  iconic storage for the duration of approximately half a second
