Silent treatment is the refusal to communicate verbally or electronically with someone who is trying to communicate and elicit a response. It may range from just sulking to malevolent abusive controlling behaviour. It may be a passive-aggressive form of emotional abuse in which displeasure, disapproval and contempt is exhibited through nonverbal gestures while maintaining verbal silence.[1] Clinical psychologist Harriet Braiker identifies it as a form of manipulative punishment.[2] It may be used as a form of social rejection; according to the social psychologist Kipling Williams, it is the most common form of ostracism.
