A study of endogenous eyeblinks in primates including human from the standpoint of comparative cognitive scinence.

记录并分析了71种灵长类的眨眼行为，从眨眼频率、眨眼持续时间和唯一眨眼百分率(与头部和身体运动无关的眨眼)三个方面分析了它们的眨眼行为，并比较了可能的影响因素：1)共同术语的系统发育尺度。2)家庭水平，3)头体长，4)体质量，5)活动节律，6)栖息地类型。眨眼频率从夜间到白天、从树到陆都呈线性增加，特别是沿着系统发育尺度，如共同术语水平和家系类型水平。足底眨眼百分率也有随系统发育进程而增加的趋势，但眨眼持续时间仅受体型大小的影响。这些发现可能表明，与体型较小和虚弱的物种相比，巨型或大型物种几乎没有敌人或捕食者，降低了警惕的必要性，导致了额外的眨眼，这导致了频繁、短暂和唯一的眨眼。

The eyeblink behaviors of 71 species of primates were recorded and analyzed in terms of three types of blink attributes ; 1)eyeblink rate, 2) blink duration and 3) sole blink percent (the blinks not associated with head and body movements), comparing with the possible contributing factors ; 1) phylogenetic scale of common term. 2) of family level, 3) head body length, 4) body mass, 5) activity rhythm, and 6) habitat types. The blink frequency increased linearly from nocturnal to diurnal, arboreal to terrestrial and especially along phylogenetic scales such as common term levels and family type levels. Sole blink percents also tend to increase in accordance with phylogenetic process but blink durations were affected only by body size. These findings might suggest that the jumboized or large-sized species have little enemies or predators and decrease the necessity of vigilance, resulting in allowing extra blinks, which leads to frequent, shorter and sole blinks, compared with the smaller and feeble species.
