Vigilance is important for animals so that they may watch out for predators. Typically a reduction in alertness is observed in animals that live in larger groups. Studies on vigilance have been conducted on various animals including the scaly-breasted munia .
Researchers in psychology and cognitive science study perceptual vigilance to understand how attentional mechanisms operate and how they can be influenced by internal and external factors. By investigating the cognitive processes underlying perceptual vigilance, researchers gain insights into human perception , behavior and decision-making .
Some level of vigilance is a good thing. “It’s how we humans managed survival early on and how in normal circumstances we measure if our safety is or could be compromised,” explains ...
Norman H. "Mack" Mackworth (1917–2005) was a British psychologist and cognitive scientist known for his pioneering work in the study of boredom, attention, and vigilance; [1] the Mackworth Clock test has been used since the 1940s in the study of vigilance.
A psychomotor vigilance task (PVT) is a sustained-attention, reaction-timed task that measures the consistency with which subjects respond to a visual stimulus. Research indicates increased sleep debt or sleep deficit correlates with deteriorated alertness , slower problem solving , declined psychomotor skills , and increased rate of false ...

Watson calls Juan Luis Vives the father of modern psychology because, in his book De Anima et Vita (The Soul and Life), he was the first to recognize the importance of empirical investigation. [7]
