Once learned and practiced routinely [-], sound receiving became as easy as listening to natural-language speech; one decoded automatically, going directly from sounds to word impressions. A woman who worked on Morse code receiving as part of a massive effort at Bletchley Park to decrypt German Enigma transmissions during World War II reported that after her intense experiences there, she heard Morse code everywhere—in traffic noise, bird songs, and other ambient sounds—with her mind automatically forming the words to which the sounds putatively corresponded. Although no scientific data exist on the changes sound receiving made in neural functioning, we may reasonably infer that it brought about long-lasting changes in brain activation patterns, as this anecdote suggests.
