摘要: <正> 一、問題 这項研究是从“閃光信号的頻率选择实驗研究”总課題派生出来的一个問題。在进行上述研究,尤其是有关“閃光頻率辨认和等辨量表”的实驗时,許多被試口头报告曾使用数数法,帮助自己辨认閃光的頻率。經与实驗結果对照,发現在閃光頻率低于30—40周/分时,用数数法确实有效,頻率較高(例如100周/分以上)时,則漸难使用数数法了,其轉折点似在50周/分左右。由于閃光頻率与閃光每周的时距有一定的关系,閃光頻率的辨认,归根結底,主要是以时間知觉为基础的。

Abstract: The influence of various rhythmic sounds on the discrimination of intermittent light with lower, medium and higher frequencies were studied experimentally. Four types of rhythmic sounds were used: 1) tempo synchronized with the flash frequency; 2) tempo with no fixed relation to the flash frequence; 3) constant tempo, and 4) tempo proportional to the flash frequency.1. The synchronized sound tempo showed positive influence on the discrimination, which exhibited more strikingly with the increase of the flash frequency. Tempo with no fixed relation showed negative influence, but the influence decreased with the increase of the flash frequency. Positive influence of the constant tempo on the medium flash frequency was slightly higher than that on the lower frequency. The influence of the proportional tempo on the higher flash frequency was not significant. These findings suggested that the rhythmic sound influenced the discrimination of flash frequency through time perception.2. The discrimination of the lower flash frequency depended more on some auxiliary means, such as counting; and that for the higher frequency depended more on direct perception; with the medium frequency as a transitional stage.3. The DL of the time interval occupied by a single cycle in the intermittent light, obtained in this experiment, was lower than that obtained by authors who did not use flash light in their studies. This suggested that the summation of sensation should be taken into consideration in the determination of differential limen.
