Symptoms of a compulsive lying disorder or traits of a pathological liar beyond lying include impulsive behavior, deceptiveness, anger, abusive behavior and selfishness, according to PsychCentral. Pathological liars may also become controlling or obsessive, socially awkward or isolated and display jealous or manipulative behavior toward others.
Compulsive lying disorder may make patients prone to narcissism and cause tempermentalness on a regular basis, explains PsychCentral. These individuals may also possess low self esteem and become uncomfortable in social situations. Pathological liars typically study behaviors to determine the right time to lie or take advantage of another individual. Many people with a compulsive lying disorder may lack empathy or consciousness of how lying makes other people feel.
Pathological liars may feel guilty when lying but are unable to control the urge to tell a lie, according to PsychCentral. Many people with a compulsive lying disorder attempt to change the subject when caught in a lie because they feel uncomfortable when people ask probing questions. As a result, many pathological liars feel relieved when the topic is changed.
Individuals with a compulsive lying disorder may engage in intense eye contact when telling a lie, while others may appear to be relaxed or laid back, notes PsychCentral. Some pathological liars are very sociable and have mastered how to smile or make direct eye contact when telling a lie.
