tactile
auditory
SHORT-TERM STORE (STS) temporary, working
memory
control processes - rehearsal - coding -
decisions - retrieval strategies

NATURE OF VISUALSENSORY MEMORY

• A FORM OF MEMORY
• it persists after offset of brief stimulus
• THATS SENSORY
• affected by visual conditions (e.g., contrast,
  masks) before and after array
• WITH LARGE CAPACITY
• big partial-report advantage at 0 delay
• BUT BRIEF DURATION
• advantage is lost if delay is gt 250 msec
