Rationale: Chronic heroin use can cause deficits in response inhibition, leading to a loss of control over drug use, particularly in the context of drug related cues. Unfortunately, heightened incentive salience and motivational bias in response to drug related cues may exist following abstinence from heroin use.Methods: Sixteen long term (8 24 months) male heroin abstainers and 16 male healthy controls completed a modified two choice oddball paradigm, in which a neutral “chair” picture served as frequent standard stimuli; the neutral and drug related pictures served as infrequent deviant stimuli of different conditions respectively. Event related potentials were compared across groups and conditions.Results: Our results showed that heroin abstainers exhibited smaller N2d amplitude (deviant minus standard) in the drug cue condition compared to the neutral condition, due to smaller drug cue deviant N2 amplitude compared to neutral deviant N2.
A cross sectional convenient sample of 23,532 Norwegians (Mage=35.8 years; range=16 88 years) completed an open web based survey including the Bergen Social Media Addiction Scale (BSMAS), the Narcissistic Personality Inventory 16, and the Rosenberg Self Esteem Scale. Results demonstrated that lower age, being female, being single, being a student, lower education, lower income, lower self esteem, and narcissism were associated with higher scores on the BSMAS, explaining a total of 17.5% of the variance. The results were also consistent with demographic predictions and associations taken from central theories concerning “addiction”, indicating that females may tend to develop more addictive use of activities involving social interaction than males.
They are woefully trained, inadequately paid and unscientifically reviewed. In their hands, an exercise of discretion bounded by the law on whether to register a case or not becomes a matter of capricious choosing. Discretion is not the same thing as choice..
In his first major interview since becoming president, Mr Biden told CBS news anchor, Norah O’Donnell, the country faced a challenge to reach herd immunity before the end of the summer. The US president said the rate of vaccination had to be accelerated to meet the target of 75 per cent of Americans getting the jab set by infectious disease expert Anthony Fauci. Mr Biden said his administration had been led to believe there was far more vaccine available than turned out.
