Document Summary
Sternberg scanning task: people were given a couple of numbers and were told to remember them. Then the participants were asked if the probe item was said as quickly and as accurate as possible. Note: encoding time and response time is about 397. 2 ms without any mental comparaison. 37. 9 ms for the memory comparaison stage (for every item that you add, you have to add 37. 9. We would see that the mental comparaison number will be larger than 37. 9, the two lines will not be parallel: memory stage locus predicts an interaction. If you add two factors affect the same stage, you will get movement in your data and you will see an interaction (this is the one that happens) If you add two factors that affect different stages, you will see no interaction. Advantage: really simple logic used to isolate stages in serial process. Disadvantage: only useful when examining a simple serial process.
