Disinhibition

In psychology, disinhibition is a lack of restraint manifested in disregard of social conventions, impulsivity, and poor risk assessment. Disinhibition affects motor, instinctual, emotional, cognitive, and perceptual aspects with signs and symptoms similar to the diagnostic criteria for mania. Hypersexuality, hyperphagia, and aggressive outbursts are indicative of disinhibited instinctual drives.An organism undergoes some series of classical conditioning trials until the conditioned stimulus reliably elicits a conditioned response. At this time, the organism then undergoes extinction trials until the conditioned stimulus no longer reliably elicits the conditioned response. Disinhibition occurs when, after these extinction trials, a new, novel stimulus is presented to the organism and at which time the organism again begins to show the previously extinguished conditioned response. This phenomenon is not to be confused with spontaneous recovery, though the concepts seem similar. In psychology, disinhibition is a lack of restraint manifested in disregard of social conventions, impulsivity, and poor risk assessment. Disinhibition affects motor, instinctual, emotional, cognitive, and perceptual aspects with signs and symptoms similar to the diagnostic criteria for mania. Hypersexuality, hyperphagia, and aggressive outbursts are indicative of disinhibited instinctual drives. According to Grafman et al. 'disinhibition' is a lack of restraint manifested in several ways, affecting motor, instinctual, emotional, cognitive, and perceptual aspects with signs and symptoms e.g. impulsivity, disregard for others and social norms, aggressive outbursts, misconduct and oppositional behaviors, disinhibited instinctual drives including risk taking behaviors and hypersexuality. Disinhibition is a common symptom following brain injury, or lesions, particularly to the frontal lobe and primarily to the orbitofrontal cortex. The neuropsychiatric sequelae following brain injuries could include diffuse cognitive impairment, with more prominent deficits in the rate of information processing, attention, memory, cognitive flexibility, and problem solving. Prominent impulsivity, affective instability, and disinhibition are seen frequently, secondary to injury to frontal, temporal, and limbic areas. In association with the typical cognitive deficits, these sequelae characterize the frequently noted 'personality changes' in TBI (Traumatic Brain Injury) patients. Disinhibition syndromes, in brain injuries and insults including brain tumors, strokes and epilepsy range from mildly inappropriate social behavior, lack of control over one's behaviour to the full-blown mania, depending on the lesions to specific brain regions. Several studies in brain traumas and insults have demonstrated significant associations between disinhibition syndromes and dysfunction of orbitofrontal and basotemporal cortices, affecting visuospatial functions, somatosensation, and spatial memory, motoric, instinctive, affective, and intellectual behaviors. Disinhibition syndromes have also been reported with mania-like manifestations in old age with lesions to the orbito-frontal and basotemporal cortex involving limbic and frontal connections (orbitofrontal circuit), especially in the right hemisphere. Behavioral disinhibition as a result of damage to frontal lobe could be seen as a result of consumption of alcohol and central nervous system depressants drugs, e.g. benzodiazepines that disinhibit the frontal cortex from self-regulation and control. It has also been argued that ADHD, hyperactive/impulsive subtype have a general behavioural disinhibition beyond impulsivity and many morbidities or complications of ADHD, e.g. conduct disorder, anti-social personality disorder. substance abuse and risk taking behaviours are all consequences of untreated behavioural disinhibition. Within the realm of classical (Pavlovian) conditioning, disinhibition is a fundamental process of associative learning characterized by the recurrence of a conditioned response after extinction trials have eliminated said response elicited by the presentation of a novel stimulus. The following process best illustrates this form of disinhibition: Disinhibition is the temporary increase in strength of an extinguished response due to an unrelated stimulus effect. This differs from spontaneous recovery, which is the temporary increase in strength of a conditioned response, which is likely to occur during extinction after the passage of time. These effects occur during both classical and operant conditioning. Clinical terms sometimes gain a broader usage and meaning in society outside of their original technical definition. The concept of disinhibition is being applied with some regularity in news articles as an explanation for how youth communicate differently when using the media of instant messaging, text messaging, and posting content on social networking sites. Because technology may provide a perceived buffer from regular consequences and an actual buffer from traditional social cues, people will say and do things through technology that they would not say and do face-to-face.
