|---|---|
 whole report | task that requires observers to report everything they see in a display of items |
| IV in sperling (whole) | Number of letters in display |
| DV in sperling (whole) | response accuracy |
| key finding whole report | [Reveals a performance limitation] - Highly accurate performance if the display less than 5 letters [4.5 letters on average] - Poor performance when the displayed contained more than 5 letters |
| partial report | Task in which observers are cued to report only certain items in a display |
| key finding in partial report | Participants could accurately report 3 of the 4 letters in a row - Suggests participants had recognized 9 letters in the entire display of 12 letters |
| visual information store (VIS) | A sensory store that maintains visual information for a brief period of time (no more than 1 sec) |
| long ISI = less image clarity | why, as the interval increased the number of letters that were recalled gradually declined from 9 to 4.5? |
| sperling's information processing model | - VIS - rehearsal - auditory information store - scan component |
| rehearsal | Repeating verbal information to a) keep it active in short-term memory or b) to transfer it into long-term memory (To remember the letters until they needed to be recalled) |
| auditory information store | Maintains verbal information (e.g., the names of the different letters) in short-term memory through rehearsal |
| scan component | Determines what is recognized in the VIS |
