Food and water deprived and satiated subjects, as well as control subjects, were shown words presented tachistoscopically for .01 sec until word recognition. Five food-relevant, five water-relevant, and five neutral (animal) words of high string frequency were matched for letter confusability and letter predictability. Analyses of the data, in terms of number of presentations until recognition as well as number of words recognized at selected presentations, revealed that the amount but not the type of deprivation significantly altered word recognition. Moreover, the effect of motivation was significant already on the first slide presentation, while the effects of word characteristics (word category and generated value) occurred only after a number of presentations.
对处于食物和水剥夺状态、饱腹状态的受试者以及对照受试者进行实验，通过速示器以0.01秒的时间呈现单词，直至他们识别出单词。选取了五个与食物相关、五个与水相关以及五个中性（动物）的高频词，这些词在字母混淆度和字母可预测性方面相互匹配。对数据进行分析，分析内容包括直至识别所需的呈现次数以及在选定呈现次数时识别出的单词数量，结果显示剥夺的程度而非类型会显著改变单词识别。此外，动机的影响在第一次幻灯片呈现时就很显著，而单词特征（单词类别和生成值）的影响则在多次呈现之后才出现。
