Document Summary
Introduction: cognitive psychologists are interested in exploring the world of thoughts, representations, and mental processes that make us unique sentient beings. During the encoding phase, a subject learns a list of items, words, or pictures. For example, in a simple experiment, a researcher presents the same list of items to two different groups. She explicitly asks the experimental group to learn the presented items, while a control group is distracted. Later, during the retrieval phase, subjects are tested for their memory of the items presented during the encoding phase. George miller: demonstrated that for most short-term memory tasks, like memorizing a random sequence of numbers, people can remember about 7, plus or minus 2 items, beyond this load, the demand on short-term memory becomes strained. If rote rehearsal stops, the short-term memory fades. Chunking: miller discovered that information can reorganize into chunks of meaningful packets, greatly expanding the capacity of short-term memory.
