Interference Effects

Attention bias for alcohol has proved useful to distinguish people with a pathological consumption of people who do not, and dependents who are more likely to fall in consumption. The aim of this study was to validate the Spanish version of the Alcohol Stroop test, designed to evaluate attention biases for alcohol in alcohol-dependent patients. The sample was composed by 173 participants divided into 2 groups: 1) “Patients” (<em>n = </em>88) meeting criteria for alcohol dependence; and 2) “Control” (<em>n = </em>85) having a low risk for alcohol consumption, that completed the Stroop color naming Task (Classic Stroop), the Neutral Stroop test and the alcohol Stroop test. Statistically significant differences were found in the interference effects calculated for the Classic and Alcohol Stroop tests. Patients compared to control participants showed a higher interference effect for alcohol-related stimuli than for neutral stimuli. These effects were accounted by an attention bias for alcohol-related information in patients. ROC curves were calculated for the three interference effects, showing an area under the curve statistically significant in the Classic Stroop interference and the Alcohol Stroop interference. This study provides the validation of the Spanish version of the Alcohol Stroop test that allows to evaluate attention biases for alcohol stimuli in individuals with both pathologic alcohol consumption and alcohol dependence.

The Difference

The Stroop facilitation and interference effects as observed in the Stroop color-naming task are typically measured as the difference in naming time between the congruent or the conflicting condition and the neutral condition. The measure assumes the regression function relating the congruent or conflicting naming time to neutral naming time is linear with a slope of one and a nonzero intercept. Instead, analysis showed that the regression function subserving the facilitation effect, in fact, had a slope of less than one with a zero intercept. Analysis also showed that the regression function subserving the interference effect had a zero intercept with a greater than one slope. These results suggest that the Stroop facilitation and interference effects are the consequence of a multiplicative process by which each stage of the naming process is reduced or increased by a constant proportion. Also the appropriate measure of the Stroop effect is the ratio of the congruent (for facilitation) or the conflicting (for interference) naming time over the neutral naming time.

Abstract. Background: Previous research has demonstrated an association between alcohol-related problems and suicidal ideation (SI). Aims: The present study evaluated, simultaneously, alcohol consequences and symptoms of alcohol dependence as predictors of SI after adjusting for depressive symptoms and alcohol consumption. Method: A sample of 298 Alaskan undergraduates completed survey measures, including the Young Adult Alcohol Consequences Questionnaire, the Short Alcohol Dependence Data Questionnaire, and the Beck Depression Inventory – II. The association between alcohol problems and SI status was evaluated using sequential logistic regression. Results: Symptoms of alcohol dependence (OR = 1.88, p < .05), but not alcohol-related consequences (OR = 1.01, p = .95), emerged as an independent predictor of SI status above and beyond depressive symptoms (OR = 2.39, p < .001) and alcohol consumption (OR = 1.08, p = .39). Conclusion: Alcohol dependence symptoms represented a unique risk for SI relative to alcohol-related consequences and alcohol consumption. Future research should examine the causal mechanism behind the relationship between alcohol dependence and suicidality among university students. Assessing the presence of dependence symptoms may improve the accuracy of identifying students at risk of SI.

Specificity Effects

We examined the relative contribution of specific components of multidimensional anxiety to cognitive biases in the processing of threat-related information in three experiments. Attentional bias was assessed by the emotional Stroop word color-naming task, interpretative bias by an on-line inference processing task, and explicit memory bias by sensitivity (d') and response criterion (β) from word-recognition scores. Multiple regression analyses revealed, first, that phobic anxiety and evaluative anxiety predicted selective attention to physical- and ego-threat information, respectively; cognitive anxiety predicted selective attention to both types of threat. Second, phobic anxiety predicted inhibition of inferences related to physically threatening outcomes of ambiguous situations. And, third, evaluative anxiety predicted a response bias, rather than a genuine memory bias, in the reporting of presented and nonpresented ego-threat information. Other anxiety components, such as motor and physiological anxiety, or interpersonal and daily-routines anxiety made no specific contribution to any cognitive bias. Multidimensional anxiety measures are useful for detecting content-specificity effects in cognitive biases.

Reverse Pattern

The Stroop task has been employed to study automaticity or failures of selective attention for many years. The effect is known to be asymmetrical, with words affecting color naming but not vice versa. In the current work two auditory-visual Stroop-like tasks were devised in order to study the automaticity of pitch processing in both absolute pitch (AP) possessors and musically trained controls without AP (nAP). In the tone naming task, participants were asked to name the auditory tone while ignoring a visual note name. In the note naming task, participants were asked to read a note name while ignoring the auditory tone. The nAP group showed a significant congruency effect only in the tone naming task, whereas AP possessors showed the reverse pattern, with a significant congruency effect only in the note reading task. Thus, AP possessors were unable to ignore the auditory tone when asked to read the note, but were unaffected by the verbal note name when asked to label the auditory tone. The results suggest that pitch identification in participants endowed with AP ability is automatic and impossible to suppress.

Introduction. There are variable patterns of alcohol consumption in Russia that differ significantly between the regions. Awareness and knowledge of those regional differences are key to the effectiveness of measures to prevent and minimise possible damage to public health caused by alcohol consumption. The purpose. To identify regional characteristics of the dynamics of alcoholism and alcoholic psychosis and dependencies with indicators of the implementation and consumption of alcohol in Mari El in 2006-2017. Material and methods. In a retrospective analysis, they included state statistics and bulletins of the Office of Rospotrebnadzor on RME on the primary incidence and prevalence of alcohol dependence syndrome, chronic alcoholism, AP, acute alcohol poisoning, sales of alcohol through a distribution network in 2006-2017. Results. In the reported period of 2006-2017 there was a decline in determination coefficient (R2) from 0.76 to 0.96 for newly diagnosed cases of alcohol dependence in general, alcoholic psychosis and alcoholism in Mari El. There was a significant decline from 221.6 to 47.5 per 100 thousand in the range of values between regions, but higher rates remained among the rural and urban areas (p = 0.0002). The dynamics of the prevalence of alcoholic psychotic disorders and alcoholism were also on decline. Conclusion. The direction and extent of changes in the medical consequences of alcohol consumption (such as primary morbidity and prevalence of alcohol dependence syndrome, alcoholic psychosis and alcoholism, average duration of the course, number of alcoholic psychosis) in the region and indicators of the implementation and consumption of alcoholic beverages in the reported period can be evaluated as positive. It is crucial to ensure the positive trend in the alcohol consumption pattern and impact on public health in the region becomes a long-lasting one. At the same time, it is necessary to increase attention to the assistance and treatment provided to drug users patient.

Disulfiram has been widely used for over six decades in the treatment of alcohol dependence, as an aversive therapeutic agent. Despite having very few side effects when taken without concurrent alcohol consumption, some of these may underlie serious clinical complications. Epileptic seizure induction is a rare adverse effect of disulfiram and its aetiological mechanism is unknown. We present a hospitalised 47-year-old male patient with two episodes of generalised tonic-clonic seizures during treatment with disulfiram while abstinent from alcohol.

Abstract Background The progression of Huntington’s disease (HD) for gene-expanded carriers is well-studied. Natural aging effects, however, are not often considered in the evaluation of HD progression. Objective To examine the effects of natural aging for healthy controls and to develop normative curves by age, sex, and education from the distribution of observed scores for the Symbol Digit Modalities Test, Stroop Word Reading Test, Stroop Color Naming Test, Stroop Interference Test, Total Motor Score, and Total Functional Capacity (TFC) from the Unified Huntington’s Disease Rating Scale (UHDRS) along with a composite score. Methods After combining longitudinal REGISTRY and Enroll-HD data, we used quantile regression and natural cubic splines for age to fit models for healthy controls (N = 3,394; N observations = 8,619). Normative curves were estimated for the 0.05, 0.25, 0.50, 0.75, and 0.95 quantiles. Two types of reference curves were considered: unconditional curves were dependent on age alone, whereas conditional curves were dependent on age and other covariates, namely sex and education. Results Conditioning on education was necessary for the Symbol Digit, Stroop Word, Stroop Color, Stroop Interference, and composite UHDRS. Unconditional curves were sufficient for the Total Motor Score. TFC was unique in that the curve was constant over age with its intercept at the maximum score (TFC = 13). For all measures, sex effects were minimal, so conditioning on sex was unwarranted. Conclusions Extreme quantile estimates for each measure can be considered as boundaries for natural aging and scores falling beyond these thresholds are likely the result of disease progression. Normative curves and tables are developed and can serve as references for clinical characterization in HD.
