Twenty English-Japanese bilingual subjects were given the following reading tasks: timed, silent reading of passages in English and Japanese followed by comprehension tests and recognition of tachistoscopic presentations of twenty words in each language. The amount of reading the subjects had done in English and Japanese was assessed in an interview. Reading efficiency was determined by multiplying the number of words per minute by the per cent of correct responses on the comprehension test. More efficient readers scored higher on immediate word recognition and it was found that both reading efficiency and immediate word recognition were related to the amount of reading the subjects had done in the language.
