ABSTRACTA key feature of the brain’s ability to tell time and generate complex temporal patterns is its capacity to produce similar temporal patterns at different speeds. For example, humans can tie a shoe, type, or play an instrument at different speeds or tempi—a phenomenon referred to as temporal scaling. While it is well established that training improves timing precision and accuracy, it is not known whether expertise improves temporal scaling. We quantified temporal scaling and timing precision in musicians and non-musicians as they learned to tap a Morse code sequence. We found that controls improved significantly over the course of days of training at the standard speed. In contrast, musicians exhibited a high level of temporal precision on the first day, which did not improve significantly with training. Although there was no significant difference in performance at the end of training at the standard speed, musicians were significantly better at temporal scaling—i.e., at reproducing the learned Morse code pattern at faster and slower speeds. Interestingly, both musicians and non-musicians exhibited a Weber-speed effect, where absolute temporal precision sharpened when producing patterns at the faster speed. These results are the first to establish that the ability to generate the same motor patterns at different speeds improves with extensive training and generalizes to non-musical domains.

The use of Morse code in rehabilitation applications is usually taught by visual or auditory methods. Yet, people experienced in Morse code use in land-line and radio telegraphy suggest that encoding and decoding rates can be enhanced through primary reliance on auditory methods for mastering the code. This study investigated the best way to learn Morse code. Sixty healthy adults with no preliminary knowledge of Morse code, ages 18 to 30 years, participated. Subjects were randomly divided into three groups to learn the Morse code through three different methods: visual chart reference method; auditory method using computer software; and combined method. After the practice period, the encoding rate and accuracy were tested using a handwriting test. One-way analysis of variance was used for each of the two measurements: time and error. Subjects from the combined method group were significantly faster than subjects from the visual method, and had significantly fewer errors than subjects in the auditory method. Therefore, if both time and accuracy of conveyance are important, it appears that learning through both the visual and the auditory systems allow the subjects best to internalise the codes as language. These conclusions should apply not only for the teaching of clients, but also when mastering the Morse code as clinicians.
