组块是指由意义上相联系或形式上相类似的一些小单位组合而成的大单位。是美国心理学家米勒1956年首次提出来的一个概念。米勒认为人的短时记忆限度为7±2,但这个限度不是单个信息的项目数,而是其组块数。如“360422681002364”是一串15个小单位的数字,它是某持证人《居民身份证》上的号码。因为超出了人的短时记忆限度,很难记忆。如果按照一定的意义,组合为36(省号)、0422(县号)681002(持证人出生号)364(所在地派出所号)4个组块,就容易被人们所
Block refers to large units that are composed of small units that are related or similar in meaning. It was a concept proposed by American psychologist Miller for the first time in 1956. Miller thinks that the person’s short-term memory limit is 7±2, but this limit is not the number of items of a single message, but the number of blocks. For example, “360422681002364” is a string of 15 small-unit numbers, which is the number on the “ID card” of a certain holder. Because it exceeds people’s short-term memory limit, it is difficult to remember. According to a certain sense, the combination of 36 (provincial), 0422 (county) 681002 (certificate birth number) 364 (local police station number) 4 blocks, it is easy for people
