Tactile syllable equivalents were constructed that map relevant articulatory gestures onto the left forearm in a quasi-isomorphic way [cf. H. G. Piroth, J. Acoust. Soc. Am. Suppl. 1 79, S73 (1986)]. The patterns were delivered by the 16-channel 'system for electrocutaneous stimulation SEHR-2' [H. G. Tillmann and H. G. Piroth, J. Acoust. Soc. Am. Suppl. 1 79, S73-574 (1986)]. The present investigation was designed to determine whether a subject is able to acquire extensive inventories of tactile patterns. One subject had to train tactile obstruent-vowel syllables with a fixed vowel. During each test run, a subset of the set of tactile obstruents followed by /[open_aye]:/ was presented repeatedly in a systematic order. Then, the same subset was trained in an identification test with a feedback after each stimulus. When the average recognition rate yielded 80%, the subset was enlarged. After 35 test runs, the subject could identify 12 obstruent patterns (/[pee],[tee],[kay],[bee],[dee],[gee],[eff],[sh],&ex;,[vee],[yog],[vee_with_swirl]/) at criterion levels. Training the complete set of 16 patterns (/[ess],[zee],[cee_with_cedilla],[jay]/added), he just failed to reach the criterion after 39 additional test runs (75.8%). [ABSTRACT FROM AUTHOR] |
