Abstract

BACKGROUND

To determine the blink patterns of newscasters.

METHODS

The blink patterns of 39 professional newscasters (24 Japanese and 19 non-Japanese, 19 men and 20 women, mean age: 34.5 +/- 6.5 years) were analyzed by a blink analyzer in this observational case series. Sixty-four normal Japanese volunteers (35 men and 29 women, mean age: 31.2 +/- 7.6 years) were used as lay normal controls.

RESULTS

The maximum, mean, and coefficient of variation (CV) of interblinking time (IBT: the time between one blink and the next) in newscasters were 2.36 +/- 0.90 s (P < 0.0005), 0.95 +/- 0.27 s (P < 0.0005), and 0.76 +/- 0.25 (P < 0.0005), respectively, while those of the controls were 8.87 +/- 3.96 s, 4.01 +/- 2.05 s, and 0.55 +/- 0.21, respectively. The maximum, mean, and CV of the blinking time (BT: the length of time for each blink) of newscasters were 0.71 +/- 0.43 s (P < 0.0005), 0.29 +/- 0.11 s (P < 0.0005), and 0.55 +/- 0.25 (P < 0.0005), respectively. The values were longer when compared with normal controls, which were also significantly different, 0.35 +/- 0.12 s, 0.20 +/- 0.04 s and 0.23 +/- 0.09, respectively.

CONCLUSIONS

The six blink-related factors varied between newscasters and normal controls. Newscasters blink more often with greater irregularity.

摘要

背景

确定新闻播音员的眨眼模式。

方法

在这个观察性病例系列中，通过眨眼分析仪分析了39名专业新闻播音员（24名日本人，19名非日本人，19名男性，20名女性，平均年龄：34.5±6.5岁）的眨眼模式。64名正常日本志愿者（35名男性，29名女性，平均年龄：31.2±7.6岁）作为普通正常对照。

结果

新闻播音员的眨眼间隔时间（IBT：一次眨眼与下一次眨眼之间的时间）的最大值、平均值和变异系数（CV）分别为2.36±0.90秒（P<0.0005）、0.95±0.27秒（P<0.0005）和0.76±0.25（P<0.0005），而对照组的分别为8.87±3.96秒、4.01±2.05秒和0.55±0.21。新闻播音员的眨眼时间（BT：每次眨眼的持续时间）的最大值、平均值和CV分别为0.71±0.43秒（P<0.0005）、0.29±0.11秒（P<0.0005）和0.55±0.25（P<0.0005）。与正常对照组相比，这些值更长，正常对照组的相应值分别为0.35±0.12秒、0.20±0.04秒和0.23±0.09秒，差异也很显著。
