Memory is the processes involved in retaining, retrieving, and using information about stimuli, images, events, ideas, and skills after the original information is no longer present. We many not be aware of how our memory works or even if we have certain memories or not but they may nevertheless affect our behavior. Today The “Modal” Model • Atkinson & Shiffrin’s (1968) Information processing model: msec-sec 15-30 sec years Remembering a Phone Number

2 Major Memory Components The Sensory Store • Atkinson & Shiffrin’s (1968) Information processing model: msec-sec 15-30 sec years The Sensory Store • For visual information known as Iconic Memory • Supports the retention for brief periods of • Supports the retention, for brief periods of time, of the effects of sensory stimulation. • Visual persistence : The apparent persistence of a visual stimulus beyond its physical duration. What is it good for? • Eye movements • Blinks • Attentional processes take some time. • Adaptive in that it allows action without pausing to stare at the input. • But how can it be measured? Sperling (1960) • Whole report: – 50 msec exposure: – Which letters did you see? – People remember 4-5 letters. Dt h i t h t XMLT AFNB • Does this means that there is a very small iconic store? • Or, is the iconic store large but quick to lose information? (By the time you report the first 4-5 letters it fades away). C D Z P Sperling (1960) • Partial report: – 50 msec exposure: – Immediately followed by a tone cuing one of the 3 rows. – Which letters did you see in Which letters did you see in that row? – People remember 3-4 letters. • This means that people initially have good memory for the whole display but it fades away before they can report the entire display.

3 Whole vs. Partial vs. Delayed For how long does information stay in the iconic store? For how long does information remain in the Iconic Store? What kind of information is represented? raw represented? raw-visual or object visual or object- based? • Partial report with a twist: – 50 msec exposure: – Immediately followed by a tone cuing whether to report letters or digits. – Which digits or letters did you see? – People perform like in the full recall X2L9 0F8B condition. • This means that object knowledge (is it a digit or a letter?) is not included in this representation. • By the time people respond to this prompt the content of the iconic store fades away.
