Aphasia for Morse code: a comment on Wyler and Ray (1986).
A. R. Wyler and R. W. Ray (1986, Brain and Language, 27, 195-199), present a case of aphasia for Morse code; they relate the deficit to the inability to detect high-speed auditory temporal sequences. Based on a personal observation of transient aphasia for Morse code, we proposed that at least three different abilities participate in recognizing and producing Morse code messages: (1) a specific linguistic ability, (2) a praxic skill, and (3) an auditory discrimination skill. Our patient presents difficulties in the first and second abilities, Wyler and Ray's in the third ability.
