Document Summary
Sternberg: scanning task: wanted to know how long it takes for us to make one mental comparison in stm, test: gave a memory set (9,4,1,6,3,8), then pause, then probe. Yes/no response to probe being part of the set: dependent variable is measure of performance (response time), time between the presentation of a probe stimulus and the response is filled up with a series of discrete stages. Compare the probe item to the first item in memory, then move to the second: you always go through the whole set. If you have fewer items, it takes faster time to get to the end then it would for a large set: time between each item is 37. 9 ms, serial self-terminating: comparing items to probe one at a time. Additive factors logic and modelling: what is the nature of the representations that are being compared.
