Blinking in deceptive communication
MetadataShow full item record
Reviews on blinking and deception have considered blinking as a thinking clue and more recent writing identifies differences in blinking behavior depending on the emotional expression that accompanies the lie (e.g. liars who mask their emotions with another emotion blink more than truth-tellers, whereas liars who neutralize their facial expression blink less). Taking this more recent approach into account, the current examines the relationship between veracity and blinking depending on the facial expression used during lying. The author's findings suggest that blinking behavior in liars (compared to truthtellers) increases when they mask emotion and decreases when they attempt to stay "poker-faced." Past reviews are challenged and suggestions are made for future research.
