Alexithymia And Drinking In Young Adults: The Role Of Alcohol-Related Intrusive Thoughts, Michael Lyvers, Olena Lysychka, Fred Thorberg
Alexithymia And Drinking In Young Adults: The Role Of Alcohol-Related Intrusive Thoughts, Michael Lyvers, Olena Lysychka, Fred Thorberg
Mike Lyvers
Alexithymia refers to difficulties identifying and describing emotions, an externalised thinking style and a lack of imagination. Alexithymia has been linked to heavier drinking in community samples and is strongly associated with alcohol use disorders. Among patients undergoing treatment for alcohol dependence, alexithymia is associated with more intrusive thoughts about drinking. The present research asked whether this may also be the case in a non-clinical sample of social drinkers and whether such intrusive thoughts mediate the relationship between alexithymia and drinking. Participants were 113 university undergraduates aged 18–30 years who completed self-report indices of alexithymia (Toronto Alexithymia Scale-20, or TAS-20), …

Caffeine Use And Alexithymia In University Students, Michael Lyvers, Natalija Duric, Fred Thorberg

Alexithymia refers to difficulties with identifying, describing, and regulating one’s own emotions. This trait dimension has been linked to risky or harmful use of alcohol and illicit drugs; however, the most widely used psychoactive drug in the world, caffeine, has not been examined previously in relation to alexithymia. The present study assessed 106 male and female university students aged 18-30 years on their caffeine use in relation to several traits, including alexithymia. The 18 participants defined as alexithymic based on their Toronto Alexithymia Scale (TAS-20) scores reported consuming nearly twice as much caffeine per day as did non-alexithymic or borderline …
Trait Impulsivity Predicts D-Kefs Tower Test Performance In University Students, Michael Lyvers, Vanessa Basch, Helen Duff, Mark Edwards
Trait Impulsivity Predicts D-Kefs Tower Test Performance In University Students, Michael Lyvers, Vanessa Basch, Helen Duff, Mark Edwards

The present study examined a widely used self-report index of trait impulsiveness in relation to performance on a well-known neuropsychological executive function test in 70 university undergraduate students (50 women, 20 men) aged 18 to 24 years old. Participants completed the Barratt Impulsiveness Scale (BIS-11) and the Frontal Systems Behavior Scale (FrSBe), after which they performed the Tower Test of the Delis-Kaplan Executive Function System. Hierarchical linear regression showed that after controlling for gender, current alcohol consumption, age at onset of weekly alcohol use, and FrSBe scores, BIS-11 significantly predicted Tower Test Achievement scores, b¼_.44, p
Blood Alcohol Concentration Is Negatively Associated With Gambling Money Won On The Iowa Gambling Task In Naturalistic Settings After Controlling For Trait Impulsivity And Alcohol Tolerance, Michael Lyvers, Nicole Mathieson, Mark Edwards
Blood Alcohol Concentration Is Negatively Associated With Gambling Money Won On The Iowa Gambling Task In Naturalistic Settings After Controlling For Trait Impulsivity And Alcohol Tolerance, Michael Lyvers, Nicole Mathieson, Mark Edwards

Introduction: Acute alcohol intoxication has been found to increase perseverative errors on the Wisconsin Card Sorting Test, a well known neuropsychological index of prefrontal cortical functioning, in both laboratory and naturalistic settings. Method: The present study examined the relationship between levels of alcohol consumption at campus drinking venues and performance of the Iowa Gambling Task (IGT), another neuropsychological test designed to assess prefrontal cortex dysfunction, after controlling for potential confounding variables including habitual alcohol intake (as a proxy for alcohol tolerance), trait impulsivity, and everyday executive functioning. Results: The 49 participants of both genders aged 18 to 30 years were …
Cognitive Trait Anxiety, Situational Stress, And Mental Effort Predict Shifting Efficiency: Implications For Attentional Control Theory, Elizabeth Edwards, Mark Edwards, Michael Lyvers
Cognitive Trait Anxiety, Situational Stress, And Mental Effort Predict Shifting Efficiency: Implications For Attentional Control Theory, Elizabeth Edwards, Mark Edwards, Michael Lyvers
Mike Lyvers
Attentional control theory (ACT) predicts that trait anxiety and situational stress interact to impair performance on tasks that involve attentional shifting. The theory suggests that anxious individuals recruit additional effort to prevent shortfalls in performance effectiveness (accuracy), with deficits becoming evident in processing efficiency (the relationship between accuracy and time taken to perform the task). These assumptions, however, have not been systematically tested. The relationship between cognitive trait anxiety, situational stress, and mental effort in a shifting task (Wisconsin Card Sorting Task) was investigated in 90 participants. Cognitive trait anxiety was operationalized using questionnaire scores, situational stress was manipulated through …
