Mood, Mood Regulation, And Frontal Systems Functioning In Current Smokers, Long-Term Abstinent Ex-Smokers, And Never-Smokers, Michael Lyvers, Cassandra Carlopio, Vicole Bothma, Mark Edwards
Mood, Mood Regulation, And Frontal Systems Functioning In Current Smokers, Long-Term Abstinent Ex-Smokers, And Never-Smokers, Michael Lyvers, Cassandra Carlopio, Vicole Bothma, Mark Edwards

Indices of mood, mood regulation, and executive functioning were examined in 61 current smokers who have smoked daily for at least one year, 36 ex-smokers who had not smoked a cigarette for at least one year, and 86 never-smokers. All participants completed the following measures online: Depression Anxiety Stress Scales (DASS-21), the Negative Mood Regulation (NMR) scale, the Frontal Systems Behavior Scale (FrSBe), the Fagerström Test for Cigarette Dependence (FTCD), and the Alcohol Use Disorders Identification Test (AUDIT). Multivariate analysis of variance (MANOVA) followed by Tukey post-hoc tests revealed significant differences (p
Impulsivity, Executive Cognition And Reward Sensitivity In Relation To Excessive Or Problematic Alcohol Consumption, Michael Lyvers, Mark Edwards
Impulsivity, Executive Cognition And Reward Sensitivity In Relation To Excessive Or Problematic Alcohol Consumption, Michael Lyvers, Mark Edwards
Mike Lyvers
Background: Deficits of frontal lobe functioning and associated cognitive impairments are well known correlates of chronic alcoholism and are commonly interpreted as reflecting cumulative effects of high alcohol exposure (Lyvers, 2000). Alternatively, such associations may reflect traits predating alcohol exposure which predispose to risky drinking . For example, university students have a higher prevalence of alcohol use as well as risky drinking than do non-students of the same age, yet not all students drink at risky levels, suggesting that excessive alcohol use by young adults may be influenced by underlying trait factors in addition to social factors. Recent studies using …
Alexithymia And Alcohol: The Roles Of Punishment Sensitivity And Drinking Motives, Michael Lyvers, Penelope Hasking, Bonnie Albrecht, Fred Thorberg
Alexithymia And Alcohol: The Roles Of Punishment Sensitivity And Drinking Motives, Michael Lyvers, Penelope Hasking, Bonnie Albrecht, Fred Thorberg

Alexithymia refers to difficulties identifying and describing feelings. It is suspected of being a risk factor for problematic drinking, an idea examined by this study. In 178 women and 84 men alexithymia was associated with male gender, coping motives for drinking and sensitivity to punishment. Individuals with alexithymia reported stronger coping motives and sensitivity to punishment compared to those with borderline or no alexithymia. Path analysis indicated that the relationship between the alexithymia dimension difficulties identifying feelings and coping motives was mediated by sensitivity to punishment, and the relationship between sensitivity to punishment and risky drinking was mediated by coping …
Illicit Use Of Lsd Or Psilocybin, But Not Mdma Or Nonpsychedelic Drugs, Is Associated With Mystical Experiences In A Dose-Dependent Manner, Michael Lyvers, Molly Meester
Illicit Use Of Lsd Or Psilocybin, But Not Mdma Or Nonpsychedelic Drugs, Is Associated With Mystical Experiences In A Dose-Dependent Manner, Michael Lyvers, Molly Meester
Mike Lyvers
Psychedelic drugs have long been known to be capable of inducing mystical or transcendental experiences. However, given the common “recreational” nature of much present-day psychedelic use, with typical doses tending to be lower than those commonly taken in the 1960s, the extent to which illicit use of psychedelics today is associated with mystical experiences is not known. Furthermore the mild psychedelic MDMA (“Ecstasy”) is more popular today than “full” psychedelics such as LSD or psilocybin, and the contribution of illicit MDMA use to mystical experiences is not known. The present study recruited 337 adults from the website and newsletter of …
Rash Impulsiveness And Reward Sensitivity In Relation To Risky Drinking By University Students: Potential Roles Of Frontal Systems, Michael Lyvers, Helen Duff, Vanessa Basch, Mark Edwards
Rash Impulsiveness And Reward Sensitivity In Relation To Risky Drinking By University Students: Potential Roles Of Frontal Systems, Michael Lyvers, Helen Duff, Vanessa Basch, Mark Edwards
Mike Lyvers
Background: Two forms of impulsivity, rash impulsiveness and reward sensitivity, have been proposed to reflect aspects of frontal lobe functioning and promote substance use. The present study examined these two forms of impulsivity as well as frontal lobe symptoms in relation to risky drinking by university students. Methods: University undergraduates aged 18–26 years completed the Alcohol Use Disorders Identification Test (AUDIT), Barratt Impulsiveness Scale (BIS-11), Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), Frontal Systems Behavior Scale (FrSBe), and a demographics questionnaire assessing age, gender, and age of onset of weekly drinking (AOD). Results: AUDIT-defined harmful drinkers reported earlier …
