Impulsivity differentially affects disorders involving the overcontrol of food intake (such as anorexia nervosa) and disorders involving the lack of control of food intake (such as bulimia nervosa). Cognitive impulsivity, such as risk-taking, is a component of many eating disorders, including those that are restrictive. [56]
Impulse-control disorder (ICD) is a class of psychiatric disorders characterized by impulsivity – failure to resist a temptation, an urge, or an impulse; or having the inability to not speak on a thought.
The Barratt Impulsiveness Scale (BIS) is a widely used measure of impulsiveness.It includes 30 items that are scored to yield six first-order factors (attention, motor, self-control, cognitive complexity, perseverance, and cognitive instability impulsiveness) and three second-order factors (attentional, motor, and non-planning impulsiveness).
The impulse delivered by a varying force is the integral of the force F with respect to time: =. The SI unit of impulse is the newton second (N⋅s), and the dimensionally equivalent unit of momentum is the kilogram metre per second (kg⋅m/s).
Impulsivity has been found to exhibit a different developmental trajectory than reward or sensation seeking. [30] Impulsivity gradually declines with age in a linear fashion. [ 31 ] Around mid-adolescence when impulsivity and sensation-seeking are at their peak is the theoretical peak age for risk-taking according to the dual systems model.
Inhibitory control, also known as response inhibition, is a cognitive process – and, more specifically, an executive function – that permits an individual to inhibit their impulses and natural, habitual, or dominant behavioral responses to stimuli (a.k.a. prepotent responses) in order to select a more appropriate behavior that is consistent with completing their goals.
Using animal subjects allows researchers to test whether different areas of the brain are responsible for different learning mechanisms. Specifically, Gray's theory concentrated on understanding how reward or punishment related to anxiety and impulsivity measures. His research and further studies have found that reward and punishment are under ...
Functional impulsivity is a tendency to make quick decisions when it is optimal and beneficial. This impulsivity is in contrast with dysfunctional impulsivity, which ...
