Document Summary
As long as it is rehearsed, it will persist in stss; but other stimuli distract. Participants given a trigram, then asked to count backwards from some random number (prevents rehearsal; distractor task); then asked to recall the trigram. Speaks to how fleeting (short-term) it is and how susceptible it is to interference effects. X-axis - how long before you were asked to recall (backward counting task length) Monotonic/decreasing ability to recall the trigram as a function of the increasing delay interval. Provided them with a basis of the interval for how long info can last in stm. 50% (reliable recall) - around 3 sec. Found: info that is unrehearsed can persist in stm for around 3 seconds. Another thing they found as a consequence of their results. Found: linear reduction in recall accuracy as a function of number of recall trials (more trials. Anecdotal finding from original study - created a second study for why this occurred.
