PSYB57H3 Chapter Notes - Chapter 1: Long-Term Memory, Computer Data Storage, Short-Term Memory
Document Summary
Bits: the amount of info provided by a given event: e. g. Coin toss => coin falls on heads/ tails = one bit of info. Information theory: the less likely it is, the more info it conveys: e. g. B) absolutely awful- i must"ve picked up the flu : b statement= more informative because it is much less probable. Hick - measured time it took participants to react appropriately to a set of signals: stimuli = 1-10 lights, responses = keys under participants fingers. Response time slowed down as # of stimuli increased. Results: stimulus info= tightly linked with processing time. The more info a signal provides => more time it takes a subject to respond. Response time to frequent signals = reduced: 3rd experiment: introduced sequential dependencies. E. g. certain lights followed by others at specific frequencies. Responses became faster as a signal"s probability increased and slower as it decreased.
