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.
