Liars' pupils tend to constrict because of the arousal associated with fib-telling. (True or False)
False. Liars' pupils tend to dilate because of the increased cognitive load associated with fib-telling.
False.
Contrary to popular belief, there is no clear-cut connection between lying and pupil constriction. While some studies suggest that increased arousal and anxiety may cause pupils to dilate, there is no reliable scientific evidence to indicate that lying specifically causes pupil constriction. The changes in pupil size are influenced by various factors, including lighting conditions, emotions, attention, and cognitive load. Therefore, focusing solely on pupil constriction as a reliable indicator of deception is not accurate.
