※ 引述《RogerFedEX (瑞士特快车)》之铭言:
: In 1989, in one of the first laboratory studies that tried to induce
: something like deja vu, the cognitive psychologists Larry L. Jacoby and Kevin
: Whitehouse, of Washington University in St. Louis, showed their subjects a
: long list of words on a screen. The subjects then returned a day or a week
: later and were shown another long list of words, half of which had also been
: on the first list. They were asked to identify which words they had seen
: during the first round.
: The experimenters found that if they flashed a word at extremely quick,
: subliminal speeds (20 milliseconds) shortly before its "official" appearance
: on the screen during the second round, their subjects were very likely to
: incorrectly say that it had appeared on the first list. Those results lent at
: least indirect support to the notion that if we attend to something
: half-consciously and then give it our full attention, it can appear falsely
: familiar.
: "falsely familiar"大概就是指"deja vu"啦
: 第二段的第一句老实讲不能完全懂它的意思
: 有神人要翻译一下的吗? (感谢)
不是神人 不过就稍微解释一下 他的意思是说
第一次实验 给受试者看很多单字
第二次实验是在第一次实验的一天或一个礼拜之後ꬊ在第二次实验提示单字的时候
在某些单字出现之前 先短暂地闪一下这个字 这个字出现的时间是20 ms
在这样的速度下 受试者可能在意识上没有办法察觉到这个字有出现过
或是只感觉到有个画面闪过 ...之类的
但是其认知仍然可能有受到影响 例如在潜意识中对该单字产生了印象
上述文章说的是"half-consciously"察觉到这个字的出现
总之 在闪过这个字之後 经过一定的时间间隔 再提示一次这个字 让受试者看个仔细
在这个情况下 受试者的判断相当可能出现错误
所谓的错误就是 将在第二次实验中第一次出现的单字误认为在第一次实验也曾出现过
也就是一种类似deja vu的效果了
