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.     

Marital interaction in alcoholic and nonalcoholic couples: alcoholic subtype variations and wives' alcoholism status

The authors examined problem-solving marital interactions of alcoholic and nonalcoholic couples (N = 132). Four alcoholic groups (husband alcoholic with antisocial personality disorder or not, paired with alcoholic or nonalcoholic wives) were compared with each other and with a both-spouses-nonalcoholic group. Consistent with the alcoholic subtypes hypothesis, couples with an antisocial alcoholic husband had higher levels of hostile behavior regardless of wives' alcoholism status. In contrast, rates of positive behaviors and the ratio of positive to negative behaviors were greatest among couples in which either both or neither of the spouses had alcoholic diagnoses and were lowest among alcoholic husbands with nonalcoholic wives. Discussion focuses on possible mechanisms linking antisocial alcoholism and discrepant alcoholic diagnoses to poorer marital outcomes.     

Differences in latent inhibition as a function of the autogenous-reactive OCD subtype

We examined differences in a visual search-based latent inhibition (LI) task in 48 non-treatment seeking individuals diagnosed with obsessive-compulsive disorder (OCD) and 26 non-OCD controls, using a visual search-based LI task as a function of participants’ primary obsessional presentation based on the autogenous-reactive subtype model of obsessions ( [Lee and Telch, 2005] and [Lee and Telch, 2007]). We hypothesized that LI would be significantly attenuated among OCD participants whose primary obsessions were characterized by aversive impulses, images, or thoughts with sexual, aggressive, blasphemous, and repulsive themes (autogenous obsessions) due to their weakened attentional inhibitory mechanisms and elevated schizotypal personality features, as compared with those whose primary obsessions were characterized by somewhat realistic aversive mental intrusions about contamination, mistakes, accidents, or disarray (reactive obsession) and non-OCD controls. Results showed that those primarily displaying autogenous obsessions failed to display LI, whereas those primarily displaying reactive obsessions and non-OCD controls displayed significant LI effects. Our data suggest that the magnitude of LI varies as a function of primary obsessional presentations among individuals with OCD.     

Favouritism as a function of assumed similarity and anticipated interaction

Discussions of intergroup behavior (e.g., Rabbie and Wilkens, 1971; Tajfel, Flament, Billig and Bundy, 1971) have drawn attention to the influence of both assumed similarity and anticipated future interaction between an individual and other members of his group on his tendency to assign more favourable outcomes to members of his own group than to members of another group. This note examines whether similar processes may also affect an individual's tendency to make intragroup discriminations between different members of a group to which he himself does not belong, in a situation where the variables of similarity and anticipated interaction may be treated as independent factors.     

Discrimination learning of delinquent boys as a function of reinforcement contingency and delinquent subtype

Previous research has demonstrated the effectiveness of contingency management as a means of behavioral resocialization with delinquent boys on an individual basis. The present study was designed to examine and clarify systematically the reinforcement parameters that underlie the male delinquent's response to verbal and token reward and/or punishment. The principal findings of the study were: (1) Neurotic subjects performed at the highest level for punishment, at the lowest level for reward, and at an intermediate level for a combination of reward and punishment, regardless of verbal or token contingency modality. (2) Psychopathic subjects performed best for the joint verbal reward and punishment contingency, but they did not learn over trials for the joint token reward and punishment contingency. Their performance was undifferentiated at asymptote under the separate verbal and token reward or punishment contingencies. (3) Neurotic subjects performed at a significantly higher level than did psychopathic subjects for verbal and token punishment, while psychopathic subjects performed at a significantly higher level than neutric subjects for verbal and token reward.The authors wish to thank the staff and students of the Lookout Mountain School for Boys and the Golden Gate Youth Camp at Golden, Colorado, for their cooperation in this study. Special thanks are due to Mr. Loren Adlfinger, director, and Mr. George Taylor of the Lookout Mountain School for Boys, and to Mr. John P. McIlwee of the Golden Gate Youth Camp. The study was submitted in 1974 by the first author to the Graduate School of the University of Colorado in partial fulfillment of the requirements for the degree of doctor of philosophy in clinical psychology.     

Human physical aggression as a function of alcohol and threat of harm

The present study investigated the effect of threat of physical harm on the aggressive behavior of intoxicated and nonintoxicated subjects. Forty male undergraduates competed in a reaction time task in which they could deliver shock to an increasingly provocative opponent. In the threat condition, subjects could be hurt by the opponent (they wore a shock electrode), while in the no-threat condition, they could not be hurt by the opponent (the electrode was removed prior to the competition). The results indicated that under conditions of low provocation, the intoxicated subjects behaved more aggressively than the nonintoxicated subjects in both the threatening and nonthreatening condition. However, under conditions of increasing provocation, only the intoxicated subjects in the threatening condition increased their shock settings.     

Legal drinking age and alcohol consumption

Utilizing samples from two states, one where the legal age for the possession and consumption of alcohol was 18 (Louisiana) and one where the legal age was 21 (North Carolina), we examine the assumption that restricting access to alcohol results in lower alcohol consumption rates for the target population (age 18–20). We find little support for this assumption, but considerable evidence that restrictive legislation drives younger drinkers underground, resulting in overall higher consumption rates for the target population.
