Motivation and reward can have differential effects on separate aspects of sustained attention. We previously demonstrated that continuous reward/punishment throughout a sustained attention task improves overall performance, but not vigilance decrements. One interpretation of these findings is that vigilance decrements are due to resource depletion, which is not overcome by increasing overall m...

Working in monotonous environment often causes lack of concentration or fatigue in an operator and many times such non-vigilance leads to accidents. Therefore early detection of fatigued state has become essential in monotonous working environments like driving vehicle, operating machines etc. Such fatigued state often gets developed gradually and can be identified by certain symptoms. Differen...

Traditional vigilance research typically employs static stimuli presented in discrete trials within a highly structured laboratory setting with few similarities to operational environments. The current study employs a dynamic video game-based environment in which the vigilance task has crucial elements of real world detection tasks, in this case the detection of improvised explosive devices (IE...

This article shows how vigilance against racism and coloniality in the US-Mexico borderlands produces knowledge, highlighting decolonizing potential of their dynamic entanglement. Before Black Lives Matter protests police violence across United States late May 2020, many Latin@s San Diego, California, already anticipated racial discrimination light growing anti-migration sentiment. Those who to...

In some tasks that require sustained attention, vigilance levels of the operator might become very important. EEG has been proved very effective for measuring vigilance. However, many difficulties exist in this field such as how to label the EEG data, how to remove the noise from the EEG data and so on. In this paper, we introduce a very useful signal transform method, Common Spatial Pattern, t...

Vigilance is an important anti-predator behaviour that can be indicator of the predation risk faced by potential prey animals. Here, we assess collective vigilance, or vigilance level entire group, corvids (Family: Corvidae) at experimentally placed carcasses in a desert environment Australia. Specifically, explore relationship between levels and habitat which carcass was placed, time since pre...

Aggregation is thought to enhance an animal's security through effective predator detection and the dilution of risk. A decline in individual vigilance as group size increases is commonly reported in the literature and called the group size effect. However, to date, most of the research has only been directed toward examining whether this effect occurs at the population level. Few studies have ...
