PSY 211 Lecture Notes - Lecture 10: Sensory Memory, Working Memory, Interference Theory
Document Summary
Continual perception of a stimulus after it"s gone. If you don"t actively practice it, it decays quickly. Little or no decay, failures of retrieval mainly caused by interference. Study of the effects of brain damage on psychological processes. People with stm deficits can perform well on complex tasks like math or logic problems. Duration of how long that information is stored and the capacity. Peterson and peterson (1959): amount of time that information stays in stm. Would give participant letters and later would ask them to repeat the letters, they gave the participant a task during the mean time to take up their stm. Looked at how many letters participants got correct across different retention intervals in seconds. Retention intervals - starting from when they were told to remember the letters, had to count, and then repeat the letters. Memory was good in short intervals, but memory falls off rapidly as retention intervals increases.
