摘要: <正> 問題我們在“閃光信号的語义干扰”实驗研究中,对代表物体运动速度的閃光信号的三种不同編碼方案进行了比較。結果表明,以快閃代表快速、慢閃代表慢速、固定灯光代表更慢的速度所产生的語义干扰最少,因而可以孰为是最优編碼方案,并且是最符合人們的思維习慣的。但是关于語义干扰的产生,还有以下几个問题須待解答。这些問題是:1.如果最优方案的編碼是最适当的,那末,在其他方案中总有一些信号,它們的意义

Abstract: Field experiments, in which locomotive enginemen and college students served as subjects, were conducted for further study on the semantic noise in coding flash signals. The results confirmed our previous findings that the best coding system is the one in which higher rate of speed was coded by flashes of higher frequency, and lower speed by that of lower frequency, and that the reaction time and the semantic noise level were linearly related.The results also indicated that in different coding systems there exist different logical orders which have some relationship with the subject's habit of thinking, and these are important factors that influence the semantic noise level. Contrary to our expectations, no significant difference has been found between the habit of thinking of the enginemen and that of the college students. It seems probable that daily life experience is a more dominant factor than professional experience in the formation of habit of thinking relevant to our experimental conditions.
