HIGH TRAIT MOTOR IMPULSIVITY IS AN ANTECEDENT TO COCAINE-SEEKING BUT NOT OXYCODONE-SEEKING BEHAVIOR IN RODENTS
… disorders with behavioral endophenotypes (e.g. impulsivity) and exposure to environmental drug-associated cues along with complex neurobiology as precipitating factors. Impulsivity is expressed in different forms (e.g. motor impulsivity, impulsive choice) and is associated with both cocaine use …

Unmasking Impulsivity as a Glutamatergic Dysfunction Phenomenon: Presynaptic and Postsynaptic Considerations
… with multiple dimensions extending into motor activity, higher level cognition and executive functioning, reward/reinforcing attributes, and motivation. Motor impulsivity refers to the inability to withhold a response or delay gratification, and efforts to unmask its complex neurobiology …

Abuse Victimization and Impulsivity in Incarcerated Males: Examining the Roles of Affective Instability and Trauma Symptoms
… have been found to exhibit increased levels of impulsivity compared to those with no abuse history (Carli et al., 2014; Davis et al., 2017; Sergentanis et al., 2014). Given that impulsivity is a risk factor for criminal delinquency (Carroll et al., 2006; Kamaluddin et al., 2015; Zimmerman, …

Neuropsychological function as a result of chronic exposure to methadone and other opioids
… impairments within the domains of cognitive and motor impulsivity, strategic planning, cognitive flexibility, attention and memory. However other studies found no clear deficits when comparing the performance of healthy controls. The literature suggested that these neuropsychological deficits may …

Disentangling the neural correlates of attention decrement: from Cognitive Neuroscience to Cognitive Engineering
… tasks with the progressive occurrence of sensory-motor deficiencies with time-on-task. The phenomenon - called attention decrement - is characterized by increases in motor impulsivity and in response times to imperative events, and by a reduction in perceptual sensitivity. So far, the neural …

Validating a novel ADHD model for medication development
… of the line by confirming the hyperactivity and motor impulsivity of the High-Active line in two different versions of the operant Go/No-go task and within adolescent males and adult females. Interestingly, the High-Active line shows little evidence of inattention as assessed by spontaneous …

A Longitudinal Study of Adolescent Trait Impulsivity, Cognitive Flexibility, and Risk-Seeking: Associations with Co-Occurring Alcohol Use and Social Anxiety in Young Adulthood
… symptoms. The current study investigated trait impulsivity, cognitive flexibility, and risk-seeking during adolescence and associations with alcohol use and social anxiety in young adulthood. Participants included 167 adolescents (Mage = 14.07 years, SD = 0.54; 52.7% male) followed to young …

Cortical - Basal Ganglia Circuits: Control of Behaviour and Alcohol Misuse
… to filter cortical information to facilitate motor outputs only have since given way to an understanding of the basal ganglia as a relay and gating structure with functionally and structurally segregated inputs, functions and outputs. Thus, cortical – basal ganglia circuits can be segregated …

The neurobiological bases of compulsive eating
… of compulsive eating. We first investigated impulsivity (impulsive choice and impulsive action) as a potential vulnerability factor for the development of binge and compulsive eating behavior. Impulsivity has been implicated in drug addiction as well as eating disorders and obesity, but its …

Brain substrates of behavioural endophenotypes predictive of compulsive drug-seeking
… of incentive salience was unrelated to impulsivity yet was positively associated with novelty place preference and locomotor reactivity. ‘Stickiness’ – the tendency to repeat the same choice regardless of reward outcome – on a reversal learning procedure was positively associated with …

The Neurocognitive Dynamics Underlying Loss of Control in Alcohol Misuse and Addiction
… to the addiction cycle (Robbins et al., 2012): impulsivity (i.e., “actions which are poorly conceived, prematurely expressed, unduly risky or inappropriate to the situation and that often result in undesirable consequences” [Daruna & Barnes, 1993]) and compulsivity (i.e., “actions which persist …
