(EXP) » Cocktail party effect ( 鸡尾酒会效应 ) • levels of processing (deeper – better M) • Enriching encoding – Elaboration ( 联想 ) – Visual imagery and Dual-coding theory – Self-Referent Encoding ( 自引性编码 ) (EXP) Memory 33 Figure 7.8 The Atkinson and Shiffrin model of memory storage. Atkinson and Shiffrin (1971) proposed that memory is made up of three information stores. Sensory memory can hold information just long enough (a fraction of a second) for a small portion of it to be selected for longer storage. Short-term memory has a limited capacity, and unless aided by rehearsal, its storage duration is brief. Long-term memory can store an apparently unlimited amount of information for indeterminate periods. Memory 34 In last Class ¡ Memory (basic processes) ¢ Storage in Information processing theory • Sensory M – approximately ¼ second –Afterimage 视觉后像 »George Sperling (1960) • STM • LTM Memory 36 ¡ Limited capacity store that can maintain unrehearsed information for up to about 20 s ¡ Limited capacity– magical number 7 plus or minus 2 (Miller, 1956) ¢ Chunking – grouping familiar stimuli for storage as a single unit ¡ Limited duration – about 20 seconds without rehearsal ¢ Rehearsal 复述 – the process of repetitively verbalizing or thinking about the information Short Term Memory (STM) Memory 37 Figure 7.9 Peterson and Peterson’s (1959) study of short-term memory. After a warning light was flashed, the subjects were given three consonants and numbers to remember. The researchers prevented rehearsal by giving the subjects a three-digit number at the same time and telling them to count backward by three from that number until given the signal to recall the letters. By varying the amount of time between stimulus presentation and recall, Peterson and Peterson were able to measure how quickly information is lost from short-term memory.
