BCS 111 Lecture Notes - Lecture 10: Sensory Memory, Sketchpad, Hebbian Theory
Document Summary
People suck at remembering things in the middle. Better at remembering first few things and last things. Aka primacy and recency in serial positioning effects. Cowan was one of the other guys working on working memory research. Pretty good reasons to doubt that 7 is the magic number for short term capacity. Tied to keeping things in your rehearsal loop. Broadbent - when you ask people to present it to you, there"s a difference between what you tell them to do, and what they do. On average, people can recall about 7 digits from a list. People can almost always recall about 3. List for categorical items, most are 2-3 items long. You hear a list of items try to remember as many of the last digits as possible write as many as you can backwards. Not gestures, like iconic meausre, dirving, climbing rope, maxes out at 3 as well. We need to eliminate some of these confounds.
