Psychological maladjustment mediates the link between remembrances of parental rejection in childhood and loneliness in adulthood: A cross-cultural comparative study

Drawing stimulus from interpersonal acceptance-rejection theory, this multicultural study examined relations between men's versus women's remembrances of maternal and paternal acceptance-rejection in childhood and their current level of loneliness, as mediated by adults' self-reported psychological maladjustment. Adults (N = 899) from five nations (Iraq, Italy, the Netherlands, Pakistan, and the United States) responded to the Adult version of the Parental Acceptance-Rejection Questionnaire-short form for mothers and fathers, the Adult version of the Personality Assessment Questionnaire-short form, and the Interpersonal Acceptance-Rejection Loneliness Scale. Adults' remembrances of maternal and paternal rejection in childhood significantly and independently predicted feelings of loneliness but remembered paternal rejection was more strongly related to these feelings than were remembrances of maternal rejection. Psychological maladjustment fully mediated the effect of remembered maternal rejection but only partially mediated the effect of remembered paternal rejection on loneliness. There were no significant differences in these results across the five countries or genders. Overall, the results suggest that adults' remembrances of parental rejection in childhood—along with the theoretically expected development of psychological maladjustment—are likely to be associated panculturally with the experience of loneliness in adulthood.     

Slowing the Tide of Alcohol Use Disorders

Alcohol use disorders (AUDs)—a spectrum including at-risk drinking, alcohol abuse, dependence, and addiction—is a highly prevalent problem worldwide with a substantial economic impact. The toll of alcohol on individual health and healthcare systems is devastating. Alcohol is estimated to be the fifth leading risk factor for global disability-adjusted life years. Tackling the problem of AUD requires a comprehensive strategy that includes solid action on price, availability, and marketing of alcohol. Restricting or banning alcohol advertising may reduce exposure to the risk posed by alcohol at the individual and general population level. Warning labels about the cancer risks associated with drinking have a high degree of public support and may be an inexpensive and acceptable way to educate the public. Religiosity may reduce risk behaviors and contribute to health decision making related to alcohol use.

     

Self-control in action: implicit dispositions toward goals and away from temptations

Five studies examined whether, in self-control dilemmas, individuals develop an implicit disposition to approach goals and avoid temptations, psychologically as well as physically. Using a method developed by A. K. Solarz (1960; see also K. L. Duckworth, J. A. Bargh, M. Garcia, & S. Chaiken, 2002), the authors assessed the time for pulling and pushing a lever in response to goal- and temptation-related stimuli (e.g., studying and partying). The results show that individuals offset the influence of tempting activities by automatically avoiding these stimuli (faster pushing responses) and by approaching stimuli related to an overarching goal (faster pulling responses). These implicit self-control dispositions varied as a function of the magnitude of the self-control conflict, itself defined by how strongly individuals were attracted to temptations and held the longer term goal. These dispositions were further shown to play a role in successful self-control.     

Authoritarian attitudes and the expression of aggression in Kuwaiti and U.S. students

In samples of undergraduates in Kuwait (ns=70 men, 70 women) and the U.S. (ns=37 men, 81 women), scores on the F Scale were positively correlated with scores on the Buss and Perry Aggression Questionnaire.     

Management Strategies of Sexual Dysfunctions

The purpose of this essay is to discuss on the possible impact on a couple's sexual relationships when the male partner's erectile problems contribute to a sexual dysfunction on the part of the female. The complex reciprocal nature of sexual interactions emphasizes the importance of the relationship for sexual function and dysfunction. The treatment of sexual dysfunction then takes into account the contribution of factors from the couple and the system. An integrated behavioural-systems approach is applied to address both sexual and non-sexual aspects of the interaction in the marital unit. This approach outlines a range of methods that may be used during the treatment of sexual dysfunctions in order to bring about relevant changes in sexual functioning and general relationships.     

Effective Leadership and Culture in Iran: An Empirical Study

On analyse dans cet article les caractéristiques du leadership efficace en Iran, puis on envisage les liens possibles entre ce profil de leadership et les dimensions culturelles du pays. A partir des données fournies par 300 managers provenant de plus de 60 organisations relevant de trois secteurs industriels, on commence par utiliser les dimensions du projet GLOBE pour évaluer la culture iranienne dont les scores sont comparés à ceux d'autres pays. S'appuyant à la fois sur l' emic et l' etic du leadership, les auteurs développent sept dimensions du leadership: encourageant, dictatorial, visionnaire, familial, modeste, loyal et réceptif. Ils soutiennent que certaines de ces dimensions traduisent les aspects universels (ou etic ) du leadership (éncourageant, dictatorial), alors que d'autres procèdent de l' emic , c'est‐à‐dire de la spécificité culturelle du leadership (modeste, familial, loyal). Les résultats sont discutés en terme de positionnement de la culture iranienne entre des entrelacements fondamentaux et des traditions culturelles complexes. On aborde enfin la question des retombées sur les recherches à venir.     

Memory performance in abstinent 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") users

Research with animals and humans has suggested that acute and subacute use of 3,4-methylenedioxymethamphetamine (MDMA "ecstasy") may lead to memory impairment. However, research is limited by (1) low power due to small sample sizes, (2) the possible confound of polydrug use, and (3) the failure to consider intelligence as a covariate. The present study compared the memory performance on the Wechsler Memory Scale-III of 26 abstinent (2-wk. minimum) recreational MDMA users with 26 abstinent (2-wk. minimum) recreational polydrug users. Despite significantly greater polydrug use amongst these MDMA users, no significant group differences in memory were observed. Regression of total lifetime amount of MDMA use also did not predict memory performance after accounting for intelligence. In addition, the length of time since abstinence (at least 2 wk.) was not associated with an increase in memory performance. Greater total lifetime cocaine use, rather than total lifetime MDMA use, was significantly associated with greater decrements in General Memory and Delayed Verbal Memory performance.     

N-Methyl-D-aspartate receptors in the ventral tegmental area are involved in retrieval of inhibitory avoidance memory by nicotine

The interaction of opiate, cholinergic, glutamatergic and (possibly) dopaminergic inputs in the ventral tegmental area (VTA) influencing a learned behavior is certainly a topic of great interest. In the present study, the effect of intra-VTA administration of N-methyl-d-aspartate (NMDA) receptor agents on nicotine's effect in morphine state-dependent learning was investigated. An inhibitory avoidance (IA) task was used for memory assessment in male Wistar rats. Subcutaneous (s.c.) administration of morphine (5 and 7.5mg/kg) immediately after training decreased IA response on the test day, which was reinstated by pre-test administration of the same doses of the opioid; this is known as state-dependency. Moreover, pre-test administration of nicotine (0.2, 0.4 and 0.6 mg/kg, s.c.) also reversed the decrease in IA response because of post-training morphine (5mg/kg). Here, we also show that when infused into the VTA before testing, NMDA (0.01 and 0.1 microg/rat) reverse the post-training morphine effect on memory. In addition, the sub-effective doses of NMDA (0.0001 and 0.001 microg/rat) in combination with a low dose of nicotine (0.1mg/kg) which had no effects by themselves, synergistically improved retrieval of IA memory on the test day. In contrast, pre-test administration of a competitive NMDA receptor antagonist D-AP5 (0.5, 1 and 2 microg/rat) which had no effect alone prevented the nicotine reversal of morphine effect on memory. Our data indicate that NMDA receptors in the VTA are involved in the reversing effect of nicotine on morphine induced state-dependency.     

DO ADJUSTING‐AMOUNT AND ADJUSTING‐DELAY PROCEDURES PRODUCE EQUIVALENT ESTIMATES OF SUBJECTIVE VALUE IN PIGEONS?

The current experiment examined whether adjusting-amount and adjusting-delay procedures provide equivalent measures of discounting. Pigeons' discounting on the two procedures was compared using a within-subject yoking technique in which the indifference point (number of pellets or time until reinforcement) obtained with one procedure determined the value of the corresponding variable in the yoked condition with the other procedure. Behavior on each procedure was well described by a hyperbolic discounting function. Results revealed no systematic differences in the degree of discounting as measured by the discounting rate parameter of the hyperbola in Experiment 1, which used 20-mg pellets. These results were replicated in Experiment 2 using smaller, 14-mg pellets, which potentially yield more precise measurement of indifference points on the adjusting-amount procedure. The finding that estimates of the k parameter in the hyperbolic discounting function obtained with one procedure did not differ systematically from estimates obtained from the same subjects with the other procedure represents strong support for the hypothesis that the same process underlies the discounting of delayed rewards on both adjusting-amount and adjusting-delay procedures.     

Is It Justifiable to Abandon All Search for a Logic of Discovery?

In his influential paper, ‘Why Was the Logic of Discovery Abandoned?’, Laudan contends that there has been no philosophical rationale for a logic of discovery since the emergence of consequentialism in the 19th century. It is the purpose of this paper to show that consequentialism does not involve the rejection of all types of logic of discovery. Laudan goes too far in his interpretation of the historical shift from generativism to consequentialism, and his claim that the context of pursuit belongs to neither discovery nor justification is based on narrow interpretations of the contexts of discovery and justification. As a result, Laudan draws unwarranted conclusions concerning both the early and contemporary defenders of a logic of discovery. A methodological logic of discovery—which involves self‐corrective methods of hypothesis generation that promote the long‐term goals of science and which require consequential support for justification—is a type of logic of discovery that survives the shift to consequentialism.
