Paranoid social cognition
Social psychological research has proposed a mild form of paranoid cognition, paranoid social cognition, that has its origins in social determinants more than intra-psychic conflict. This perspective states that in milder forms, paranoid cognitions may be very common among normal individuals. For instance, it is not strange that people may exhibit in their daily life, self-centered thought such as they are being talked about, suspiciousness about other’ intentions, and assumptions of ill-will or hostility (i.e. people may feel as if everything is going against them). According to Kramer, (1998) these milder forms of paranoid cognition may be considered as an adaptive response to cope with or make sense of a disturbing and threatening social environment. Paranoid cognition captures the idea that dysphoric self-consciousness may be related with the position that people occupy within a social system. This self-consciousness conduces to a hypervigilant and ruminative mode to process social information that finally will stimulate a variety of paranoid-like forms of social misperception and misjudgment. This model identifies four components that are essential to understanding paranoid social cognition: situational antecedents, dysphoric self-consciousness, hypervigilance and rumination, and judgmental biases. Situational antecedents
Perceived social distinctiveness, perceived evaluative scrutiny and uncertainty about the social standing. Perceived social distinctiveness: According to the social identity theory, people categorize themselves in terms of characteristics that made them unique or different from others under certain circumstances. Gender, ethnicity, age, or experience may become extremely relevant to explain peoples behavior when these attributes make them unique in a social group.
