Abstract : The experiment was designed to study the effects of stress induced by rapid pacing upon the learning of symbols from the International Morse Code by the method of anticipation. All Ss were given (1) an initial practice session, in which they were given the correct letter following a guess as to the correct letter, (2) a test, in which they were not given information as to their guess (recall), (3) a second practice session, and (4) a second recall test. The stress was induced during the first test by presenting the symbols to the Ss at a rate of one per two seconds. A practice session followed, after which all Ss were given a test with the signals delivered at the rate of one per two seconds. The effect of the rapid pacing was to impair performance, as measured in the number of signals guessed correctly. The degree of impairment appears to interest with the level of difficulty of the material. On the final test, however, there is no evidence of impairment due to stress during the first test. Actually there is a slight facilitating effect, significant at about the 5% level. A practice session intervened between these two tests, and it is suggested that the practice at the faster rate better prepared the subjects to cope with it on the final test. Thus, despite the impairing effects of the speed-stress, it does not impair and seems to facilitate Ss in subsequent performance at that speed. (Author)
