<unk><unk> <unk>  (also known as the "Task-Evoked<unk><unk> ") is a<unk><unk>  caused by a cognitive load imposed on a human and as a result of the decrease in parasympathetic activity in the peripheral nervous system. It is found to result in a linear increase in pupil dilation as the demand a<unk>  places on the working memory increases. Beatty evaluated<unk>  in different<unk> s for short-term memory, language processing, reasoning, perception, sustained attention and selective attention and found that it fulfills Kahneman's three criteria for indicating processing load. That is, it can reflect differences in processing load within a<unk> , between different<unk> s and between individuals. It is used as an indicator of cognitive load levels in psychophysiology research.
