PSY372H5 Lecture Notes - Lecture 3: Change Detection, Forgetting Curve, Fluid And Crystallized Intelligence
Document Summary
Stm and wm are 15-30 seconds in duration (approx. ) Capacity: how much information can fit into stm: often done through chunking of information, ex: to remember phone number, capacity is enhanced through chunking of a segments of the number. Duration: extended through repetition: ex: to remember phone number, we repeat it multiple times so it can be transferred into ltm. It was often thought that fluid intelligence is something we are born with. Training must last from 15-20 mins a day for it to be effective. We can track own performance to see how well we progress each time. N-back task was used to test memory. The more we practice. : we require less neural activity to achieve proficiency b/c we have come up with better ways to do it, our brain becomes more efficient. Chimp vs. human video: stm memory task, not wm task, number matching task.
