Deception, Speaking and Writing

When addressing lying and deception in language production, it is imperative to acknowledge that behavioral indicators may play a role. This include evaluation of multiple distinct verbal and nonverbal behavioral indicators, such as gaze cues, pulse rate, hand movements, and manifestations of nervousness. Here, the role of cognitive load during speaking and writing, and how cognitive load due to the parallel tasks of deciding what to say/write, and how to say it while actually expressing the thought may be visible during language production is discussed. The assumption is that lying and deception would increase the cognitive load and that this will, to some extent, be observable through the behavioral indicators.
