Factors related to young people's attitudes to the consumption of alcohol and other psychoactive substances

In this study we analyzed variables related to the consumption of alcohol and other psychoactive substances among young people, and to their attitudes towards experimentation. The sample was made up of 775 pupils aged 12 to 16 from four secondary schools in the Principality of Asturias (northern Spain). The results obtained confirm the multi-causal nature of these phenomena. The attitudes of young people towards substance use was found to be more favourable the lower the perception of risk, the more mistaken their beliefs and the more permissive their disposition to the use of alcohol and other illegal drug. Other determining factors are their relationship with peer groups that use drugs, antisocial behaviours and attention-seeking indications.     

A functional analysis of obsessive-compulsive problems with related therapeutic procedures

This report describes the application of a functional analysis to obsessions and compulsions. The approach emphasizes a search for the independent variables which maintain obsessive-compulsive behavior in the individual client: then therapeutic procedures are designed to counteract the specific maintaining variables. The application, and outcome, of this approach to two children and one adult is described.     

Impulsivity as a predictor of smoking and alcohol consumption

This prospective study examined the relationships between impulsivity, smoking and alcohol use in a large non-clinical sample of 601 men and 4832 women working in 12 Finnish hospitals. Data on impulsivity, smoking and alcohol consumption were collected by two questionnaires with a two-year interval. At baseline, impulsivity was associated with smoking and alcohol use. After controlling for baseline smoking, impulsivity predicted increased number of cigarettes smoked per day in women (p=0.08), but not in men. After controlling for alcohol use at baseline, impulsivity predicted increased alcohol consumption similarly in both genders (p<0.01). Higher impulsivity was also associated with increased likelihood of taking up smoking or becoming a heavy drinker (p<0.05). This evidence suggests that impulsivity contributes to increasing health risk behaviours.     

A cross-cultural investigation of college student alcohol consumption: a classification tree analysis

In this cross-cultural study, the authors attempted to identify high-risk subgroups for alcohol consumption among college students. American and Greek students (N = 132) answered questions about alcohol consumption, religious beliefs, attitudes toward drinking, advertisement influences, parental monitoring, and drinking consequences. Heavy drinkers in the American group were younger and less religious than were infrequent drinkers. In the Greek group, heavy drinkers tended to deny the negative results of drinking alcohol and use a permissive attitude to justify it, whereas infrequent drinkers were more likely to be monitored by their parents. These results suggest that parental monitoring and an emphasis on informing students about the negative effects of alcohol on their health and social and academic lives may be effective methods of reducing alcohol consumption. Classification tree analysis revealed that student attitudes toward drinking were important in the classification of American and Greek drinkers, indicating that this is a powerful predictor of alcohol consumption regardless of ethnic background.     

Factors related to reductions in alcohol consumption among college students: The role of religious involvement

College students most at risk for engaging in binge drinking are members of Greek organizations and athletic teams (Grenier, Borskey, & Folse, 1998; Wechsler, Dowdall, Davenport, & Castillo, 1995). Membership in religious organizations may moderate binge drinking (O'Hare, 1990). One hundred thirty-nine college students completed the Core Alcohol and Drug Survey (Presley, Meilman, & Lyerla, 1994), the Group Identification Scale (Hinkle, Taylor, Fox-Cardamone, & Crook, 1989), and the ‘Age-Universal’ I-E - 12 (Maltby, 1999). The results indicate that gender is related to average number of drinks per week. Membership in low alcohol consumption organizations was related to decreases in the frequency of alcohol usage within the previous year, which indicates that decreasing alcohol consumption may be more effective by promoting low alcohol consumption organizations.

Learning disability as related to infrequent punishment and limited participation in delay of reinforcement tasks

By comparing for learning disabled and control children parental frequency ratings of physical punishment and of completing household tasks, this experiment tested the hypothesis that parental indulgence is associated with learning disorders. Referral children with learning problems (N=18), matched on grade and sex with those in two control groups, were rated significantly lower on both measures than were either the students referred for other reasons or the nonreferred students. The infrequent punishment suggests that some children have learning problems because of a failure to acquire adequate response inhibition tendencies, which are necessary to control inappropriate behaviors resulting from the ineffective classroom positive reinforcement system. Furthermore, the lower responsibility index suggests some of their academic problems result from limited experiences functioning under delayed reinforcement.     

Acquisition of habitual visual attention and transfer to related tasks

Extensive research has shown that statistical learning affects perception, attention, and action control; however, few studies have directly linked statistical learning with the formation of habits. Evidence that learning can induce a search habit has come from location probability learning, in which people prioritize locations frequently attended to in the past. Here, using an alternating training–testing procedure, we demonstrated that the initial attentional bias arises from short-term intertrial priming, whereas probability learning takes longer to emerge, first reaching significance in covert orienting (measured by reaction times) after about 48 training trials, and in overt orienting (measured by eye movements) after about 96 training trials. We further showed that location probability learning is persistent after training is discontinued, by transferring from a letter search task to a scene search task—emulating another characteristic feature of habits. By identifying the onset of probability learning and investigating its task specificity, this study provides evidence that probability cuing can induce habitual spatial attention.     

The influence of alcohol expectancy priming and mood manipulation on subsequent alcohol consumption

Studies showing that verbal priming can implicitly affect alcohol consumption have been used to support cognitive models of expectancies. However, because expectancy words reflect affective states as well as drinking outcomes, mediation through an affective pathway remains theoretically plausible (i.e., such words inadvertently may affect mood, which in turn influences drinking). The primary pathway was identified (and expectancy theory was tested) by comparing memory priming (using alcohol expectancy or neutral words) with mood induction (using positive or neutral music); an unrelated experiment paradigm allowed the priming manipulation to implicitly affect drinking. Men in the alcohol priming group drank significantly more than men in each of the other conditions, and, consistent with theory, men with histories of heavier drinking drank the most when primed with alcohol expectancies, indicating that expectancies can function as automatic memory processes.     

P50 sensory gating is related to performance on select tasks of cognitive inhibition

P50 suppression deficits have been documented in clinical and nonclinical populations, but the behavioral correlates of impaired auditory sensory gating remain poorly understood. In the present study, we examined the relationship between P50 gating and healthy adults’ performance on cognitive inhibition tasks. On the basis of load theory (Lavie, Hirst, de Fockert, & Viding, 2004), we predicted that a high perceptual load, a possible consequence of poor auditory P50 sensory gating, would have differential (i.e., positive vs. negative) effects on performance of cognitive inhibition tasks. A dissociation was observed such that P50 gating was negatively related to interference resolution on a Stroop task and positively related to response inhibition on a go/no-go task. Our findings support the idea that a high perceptual load may be beneficial to Stroop performance because of the reduced processing of distractors but detrimental to performance on the go/no-go task because of interference with stimulus discrimination.     

Comparing the effects of light alcohol consumption on human response to auditory and visual stimuli

The purpose of this study is to examine the effects of various levels of alcohol consumption on human response to auditory and visual stimuli in terms of reaction time, movement time, total reaction time, and error rate. Placebo level and three low-level alcohol doses were randomly assigned to 20 male university student volunteers. 30 min. after consuming the alcohol or placebo, participants responded to either auditory or visual stimuli. Total reaction time increased significantly at the mid-low dose of alcohol (0.3 g/kg). For alcohol doses less than .5 g/kg, the change in total reaction time was confined to reaction time, i.e., the processing time between onset of stimulus and onset of movement. Effects of alcohol were significantly more pronounced in the choice-type tests. Notably, the effects of alcohol on total reaction time and error rate were significant for auditory but not visual stimuli.     

A general framework for the analysis of concept identification tasks

A general framework is presented for concept identification based on hypothesis-testing theory. It is a modification of the duoprocess theory presented by Chumbley (1972). It is shown how Markov models for various complex concept identification tasks may be derived from this framework and how such models may be analyzed by making use of probability generating functions. Two experiments are described. In experiment 1 three tasks were used: two simple tasks, where the subject either only had to select the relevant dimension in order to solve the problem or only had to learn a short list of paired-associates, and a more complex task, where both processes were needed to reach the solution. The results were in general favorable to the theory. Experiment 2 was designed to test the application of the theory to the four-choice concept problem. The predictions of the theory are compared to those of the subproblem learning theory of trabasso and Bower (1964), modified to include a ‘learning-on-errors’ assumption. The fit of the duoprocess theory was reasonably good and superior to that of the subproblem learning theory.     

RASP: A system for the analysis of memory tasks

The purpose of this paper is to introduce a system for the analysis of memory tasks. The system involves four basic task dimensions, derived from an ecological analysis of memory functioning: Reproductivity (R), Acquisition (A), Sufficiency (S), and Productivity (P). Three studies are reported in which professional memory psychologists were asked to rate sets of standard laboratory and more ecologically relevant memory tasks in terms of the four RASP dimensions. In general, results implied independence across the two sets of tasks between the four dimensions. Interrater reliabilities were found to be modest to high. However, it was suggested that RASP best be used as a tool for understanding the meaningful relations that exist among dimensions within general sets or pools of tasks, for different classes of tasks, as well as for prototypical tasks. We argue that, especially when the relationship between RASP profiles for two particular tasks is crossvalidated by behavioral data, and conflict with assumptions about what memory systems or processes are involved, then there is a potential for conceptual refinement. This refinement could be attained either through an increased theoretical generalization, or through an increased theoretical precision. Based on obtained RASP information at the level of classes of tasks (e.g., episodic vs. semantic) as well as at a prototypical task level (e.g., word recall vs. prose recall), several intriguing memory phenomena are discussed. Finally, we suggest that RASP may serve as a tool for reducing the number of task-specific assumptions of what systems and processes mediate memory performance.     

An experimental examination of alcohol consumption,alcohol expectancy,and self‐blame on willingness to report a hypothetical rape

This study experimentally examined the role of victim alcohol intoxication, and self‐blame in perceiving and reporting rape to the police using a hypothetical interactive rape scenario. Participants (N = 79) were randomly assigned to consume alcohol (mean BAC = 0.07%) or tonic water before they engaged in the scenario. Alcohol expectancy was manipulated, and participant beliefs about the beverage they thought they had consumed and their feelings of intoxication were measured. Alcohol consumption and expectancy did not affect the likelihood that the nonconsensual intercourse depicted in the scenario was perceived and would be reported as rape. Participants with higher levels of self‐blame were less likely to say they would report the hypothetical rape. Self‐blame levels were higher for participants who believed they had consumed alcohol, and were associated with increased feelings of intoxication. The implications are discussed.
