Legislation systems of most countries prohibited using the handheld mobile phone while driving due to the fact that it disturbs concentration and causes hand involvement. Every phone owner is accustomed to the ringtone of his phone and almost involuntarily endeavors to pick it up or check who calls. This engages one's psychomotor skills, which in our opinion contributes to the attenuation of reaction time needed for performing other crucial functions.
The aim of the study was: (1) to evaluate the influence of the sound of a ringing mobile phone on the complex reaction time (RT) score in healthy subjects (owners), and (2) to check if there are any differences in RT when a landline phone and mobile phone ring.
To assess RT we used our system and protocol of examination, previously validated. The examination conditions were standardized. All tests were performed in the same room with the same light and general acoustic conditions. The test group consisted of 23 women and 24 men, aged 19-24 years. The examination comprised 4 sessions: Training Session (TS) during which the subjects were accustomed with the application and sample stimuli, Control Session (CS) with no telephone ringing, Landline Session (LS) with landline phone ringing, Mobile Session (MS) with mobile phone ringing.
The median RT in the study population was significantly elongated (p < 0.001) in MS. In women and in men RTs were significantly longer in MS than in CS and non-significantly longer than in LS. Reaction times in CS, LS and MS were longer in women, however the differences were not significant (p > 0.05).
We think that the specific 'bond' between a person and their private phone can significantly disrupt their attention and thus affect the attention-demanding activities.
由于使用手持移动电话会分散注意力并导致手部参与，大多数国家的立法系统都禁止在驾驶时使用移动电话。每个手机所有者都习惯了自己手机的铃声，几乎会不自觉地试图接听或查看来电者是谁。这会用到一个人的心理运动技能，而我们认为这会导致执行其他关键功能所需的反应时间缩短。
本研究的目的是：（1）评估手机铃声对健康受试者（手机拥有者）的复杂反应时间（RT）得分的影响，（2）检查当固定电话和移动电话响铃时 RT 是否存在差异。
为了评估 RT，我们使用了我们之前经过验证的系统和检查方案。检查条件是标准化的。所有测试均在相同的房间中进行，具有相同的灯光和一般声学条件。测试组由 23 名女性和 24 名男性组成，年龄在 19-24 岁之间。检查包括 4 个会话：培训会话（TS），在此期间，受测者习惯了应用程序和样本刺激；无电话响铃的对照会话（CS）；固定电话响铃的固定电话会话（LS）；移动电话响铃的移动电话会话（MS）。
在研究人群中，中位数 RT 在 MS 中明显延长（p < 0.001）。在女性和男性中，MS 中的 RT 明显长于 CS，而非显著长于 LS。CS、LS 和 MS 中的 RT 在女性中较长，但差异无统计学意义（p > 0.05）。
我们认为人与私人手机之间的这种特殊“联系”可能会严重分散他们的注意力，从而影响到需要注意力的活动。
