Mobile phone conversation decreases the ability to concentrate and impairs the attention necessary to perform complex activities, such as driving a car. Does the ringing sound of a mobile phone affect the driver's ability to perform complex sensory-motor activities? We compared a subject's reaction time while performing a test either with a mobile phone ringing or without.
The examination was performed on a PC-based reaction time self-constructed system Reactor. The study group consisted of 42 healthy students. The protocol included instruction, control without phone and a proper session with subject's mobile phone ringing. The terms of the study were standardised.
There were significant differences (p < 0.001) in reaction time in control (597 ms), mobile (633 ms) and instruction session (673 ms). The differences in female subpopulation were also significant (p < 0.01). Women revealed the longest reaction time in instruction session (707 ms), were significantly quicker in mobile (657 ms, p < 0.01) and in control session (612 ms, p < 0.001). In men, the significant difference was recorded only between instruction (622 ms) and control session (573 ms, p < 0.01). The other differences were not significant (p > 0.08). Men proofed to complete significantly quicker than women in instruction (p < 0.01) and in mobile session (p < 0.05). Differences amongst the genders in control session was not significant (p > 0.05).
The results obtained proofed the ringing of a phone exerts a significant influence on complex reaction time and quality of performed task.
手机通话会降低注意力集中的能力，并损害执行复杂活动（如驾驶汽车）所需的注意力。手机铃声是否会影响驾驶员执行复杂感觉运动活动的能力？我们比较了在手机响铃或不响铃的情况下进行测试时，被试的反应时间。
检查是在基于 PC 的反应时间自我构建系统 Reactor 上进行的。研究组由 42 名健康学生组成。方案包括指导、无手机对照和有手机响铃的适当会话。研究的条件是标准化的。
在对照（597 毫秒）、手机（633 毫秒）和指导（673 毫秒）会话中，反应时间存在显著差异（p<0.001）。女性亚组的差异也具有统计学意义（p<0.01）。女性在指导会话中的反应时间最长（707 毫秒），在手机（657 毫秒，p<0.01）和对照会话（612 毫秒，p<0.001）中反应更快。在男性中，仅在指导（622 毫秒）和对照（573 毫秒，p<0.01）会话之间记录到显著差异。其他差异无统计学意义（p>0.08）。男性在指导（p<0.01）和手机（p<0.05）会话中的完成速度明显快于女性。在对照会话中，性别差异不显著（p>0.05）。
研究结果证明，手机铃声会对复杂反应时间和任务完成质量产生显著影响。
