Abstract

We investigated the cognitive mechanisms underlying change in implicit cognitions following exposure to alcohol portrayals. More precisely, we tested in an experimental study whether this change depends on controlled or automatic processes by putting participants in a state of self-regulatory fatigue prior to being exposed to alcohol portrayals. Ninety participants were randomly assigned to a 2 (attitude measure: before vs after) × 2 (alcohol portrayal: yes vs no) × 2 (ego depletion: yes vs no) mixed design to assess whether the effects of alcohol portrayals affected cognitive resources. It was hypothesized that alcohol portrayals would have more of an impact on participants submitted to an ego-depletion task. We found a change in attitudes toward alcohol only for participants that had been exposed to alcohol portrayals, and who had not been cognitively depleted. These results suggest that these changes rely on controlled, resource-dependent processes rather than on purely associative and automatic processes. Implications regarding alcohol advertising effects on public health are discussed.  相似文献

The current study aimed to test the clinical effectiveness of a cognitive-behavioural program (CBT) specifically adapted for pathological gamblers with chronic schizophrenia, carried out in a naturalistic setting of community Mental Health Centres. Forty-four pathological gamblers with chronic schizophrenia were assigned either to a standard drug therapy for schizophrenia (control group) or to cognitive-behavioural therapy for pathological gambling plus a standard drug therapy for schizophrenia (experimental group). Psychological treatment comprised a 20-session program including psychoeducation, stimulus control, gradual exposure and relapse prevention. Therapeutic success was defined as abstinence or the occurrence of only 1 or 2 episodes of gambling during the follow-up period. While the patients treated in the experimental group showed a rate of success of 73.9%, only 19% of the participants belonging to the control group gave up gambling at the 3-month follow-up. The CBT group also did better than the control group in the number of gambling episodes and in the amount of money spent on gambling. However, the improvement of the experimental group was weaker at the 6- and 12-month follow-up. These findings support the beneficial effects of CBT as adjunctive therapy for patients with dual diagnoses (schizophrenia and pathological gambling).  相似文献

Rats were exposed to concurrent schedules in which reinforcers occurred independently of behavior. In Experiment 1, rats could control time spent in the following conditions: (1) a light, (2) white noise, and (3) the absence of both light and noise. Response-independent reinforcers occurred at the same rate during the light and the noise and at either a higher rate or not at all in the absence of both stimuli. In subsequent tests, the rats spent more time in a light and noise compound than in either light or noise alone after the absence of both stimuli had signaled no reinforcers. When the absence of both stimuli had signaled a higher rate of reinforcement, however, the rats typically spent less time in the compound than in light or noise alone. In Experiment 2, rats could control time spent in the presence of a light and of a buzzer. The reinforcement rate in the light was twice that in the buzzer. In a later test, the rats spent more time in a light and buzzer compound than in the buzzer, but less time in the compound than in the light. The results show that additive summation, suppressive summation, and stimulus averaging of time allocation occur and that response rate differences between training stimuli are not necessary for these phenomena.  相似文献

The implementation of the Agreement on Aspects of Intellectual Property Rights (TRIPS) has recently been the subject of another extension. Indeed, in a decision of 6 November 2015, the Council for TRIPS granted to the least developed countries, additional time to transpose its provisions on patents for pharmaceutical products. Consequently, least developed countries have the ability to import or manufacture locally, generic drugs, regardless of the rules on pharmaceutical patents until 1st January 2033. Such a decision is not unprecedented but it raises questions about the effectiveness of the agreement.  相似文献

Neuroscientific approaches to drug addiction traditionally have been based on the premise that addiction is a process that results from brain changes that in turn result from chronic administration of drugs of abuse. An alternative approach views drug addiction as a behavioral disorder in which drugs function as preeminent reinforcers. Although there is a fundamental discrepancy between these two approaches, the emerging neuroscience of reinforcement and choice behavior eventually may shed light on the brain mechanisms involved in excessive drug use. Behavioral scientists could assist in this understanding by devoting more attention to the assessment of differences in the reinforcing strength of drugs and by attempting to develop and validate behavioral models of addiction.  相似文献

Soap is a cosmetic product in common use during this pandemic period. It enables barrier gestures to be carried out. Capable of preventing pathology (COVID-19), it should, therefore, be marketed under a drug status. If we consider the history of soap, we realize the complexity of its status. Depending on the period, it has been considered as a hygiene product and/or as an excipient or an active ingredient allowing the production of a drug or cosmetic making it possible to treat both scabies and burns, to carry out purges or to put at the point of preparations to soften or whiten hands or to lengthen eyelashes. The use of the term “soap”, being extremely overused, the establishment of regulations to clarify this situation is essential.  相似文献

We explored the effects of drug use history (current/recent user of drugs, used/tried drugs, never tried drugs) and a measure of drug test consequences (termination versus rehabilitation) on the perceived fairness of organizational drug testing (DT). Data were collected as part of a statewide telephone survey of the general adult population. Personal drug use history and DT consequences interacted such that DT consequences were related to DT fairness only for nonusers who had past drug use experience. The importance of past drug use in understanding reactions to DT are discussed.  相似文献

Drug driving is a significant road safety concern rendering the implementation of roadside drug testing in all Australian jurisdictions. The current research sought to examine the impact of recently introduced roadside oral fluid screening in the Australian Capital Territory (ACT). Specifically, the study sought to examine drivers’ awareness, perceptions and perceived deterrent impact of these operations and the degree to which they influence likelihood of future drug driving. A total of 801 male and female motorists aged 17–88 years of age completed a phone interview assessing demographics (e.g., driving and drug taking history), awareness and perceived effectiveness of roadside drug testing, and constructs central to both Classical Deterrence Theory (i.e., certainty, severity, swiftness) and reconceptualised deterrence theory (direct and vicarious experiences of both punishment and punishment avoidance) frameworks. Overall, despite an apparent decline in drug driving behaviour since the introduction of roadside testing, a large proportion of driver’s possessed a poor awareness of these operations and did not perceive a high certainty of apprehension. Age, punishment avoidance and vicarious punishment avoidance were found to predict future likelihood of drug driving, whilst Classical Deterrence Theory variables did not. Contrary to expectations and previous studies, few significant differences were found with regards to gender. Findings are interpreted in light of the recency of roadside drug testing in the ACT and the need for future studies to examine the impact of such operations. Further recommendations for augmenting the deterrence of drug driving are discussed.  相似文献

Religious expressions and religious behaviours are often considered to be mainly mental or spiritual phenomena, to a large degree divorced from or threatened by physical or material forms that may accompany their expression. This paper asks whether the diminution of the material or the condemnation of idols, icons and religious art loses sight of possible benefits that involvement with these forms of material divinity has for believers. Using the concept of transitional objects and transitional phenomena developed by D. W. Winnicott, a mid-twentieth-century psychoanalyst, I argue that idols, icons and religious art often represent transitional objects that form psychological bridges, intermediaries or anticipated “transitions” from humans to unseen divinities who require materialisation in some form to be maintained actively in the believer’s mind. In the process of creating or designing these material forms, the forms themselves often come to be considered “divine”. Illustrations are provided.  相似文献

W.E.B. Du Bois understood the critical role religion plays in power inequities in the, world. He was very acquainted with how it is used as a tool to exclude and subordinate human beings and yet, at the same time, serve as a source of refuge. This special issue of the Journal for the Scientific Study of Religion is a collection of articles that examines religion and social inequality from a variety of different angles with a Du Boisian lens. When we focus our lens on religion and social inequality, we are highlighting the ways in which religion plays a part in the unequal distribution of power across social groups in society. This special issue focuses on how religion impacts social life and the way individuals and groups embody or struggle to reclaim their agency within a context of silent oppression at times and not-so-silent oppression at others times at the personal-, group-, and global levels.  相似文献

At the center of medical morality is the healing relationship. It is defined by three phenomena: the fact of illness, the act of profession, and the act of medicine. The first puts the patient in a vulnerable and dependent position; it results in an unequal relationship. The second implies a promise to help. The third involves those actions that will lead to a medically competent healing decision. But it must also be good for the patient in the fullest possible sense. The physician cannot fully heal without giving the patient an understanding of alternatives such that he or she can freely arrive—together with the physician—at a decision in keeping with his or her personal morality and values. In today's pluralistic society, universal agreement on moral issues between physicians and patients is no longer possible. Nevertheless, a reconstruction of professional ethics based on a new appreciation of what makes for a true healing relationship between patient and physician is both possible and necessary.  相似文献

Abstract

In a project that investigated the HIV-related risk behaviour of injecting drug users, respondents were categorized along dimensions of expertness in HIV/AIDS knowledge and knowledge about drug-related health problems. Knowledge about drug-related health problems was found to be significantly associated with sharing. Better informed respondents were less likely to share injecting equipment and to predict they would share in future. They were more likely to adopt consistent injecting hygiene, seek information about AIDS, and perceive themselves as in control of their lives. No significant relationships were observed between sharing and HIV/AIDS knowledge. The data have relevance for AIDS educational strategies, since knowledge about AIDS and HIV transmission appears to be insufficient to induce behavioural change. Greater emphasis on the health problems that afflict most injectors may be a way of encouraging general harm minimization.  相似文献

The centre of Adorno's Critical Theory is occupied by the theme of happiness. He speaks of the impaired life, of the unjustness of society, of murderous prejudices, of the atrocities in history, of the dissonance in art, of the unhappy consciousness, because something better can only be described from a point of opposition. Happiness cannot be objectified as possession, it always needs to be experienced subjectively, somatically. (With happiness it is like with truth: One does not have it, one is in it.) Happiness cannot be prescribed and ordered; nothing can be done to guarantee happiness. (Happiness goes beyond doing.) Happiness (like fear) has to do with being open to experience which can overwhelm the self. Sexual and aesthetical experience are models for such overwhelming happiness. The sensation of happiness always is very personal, but in this experience the individual leaves its particularity behind. One has to differentiate between goal and object: Happiness may be a goal, but not it itself, only what obstructs it, can be an object of Critical Theory.  相似文献

传统的精神疾病诊断以一种经验式的分类手册来诊断精神疾病,而莱因主张从存在主义——现象学的视角来理解精神疾病,认为家庭或社会才是精神疾病的真正来源。在精神疾病的治疗方面,莱因主张通过改变患者的生存环境来促使其进行自我恢复。莱因的思想推动了当代精神病学的变革与发展,具有重要的现实意义。  相似文献

The golden anniversary of Science and Human Behavior is cause for celebration. Toward that end, the present paper is largely an historical consideration of the book, its inception and reception, both at the time of its publication and in subsequent years. The range and intensity of reactions to S&HB mark its impact and show it to be among Skinner's most important works, if not the most important. S&HB was written as an introductory psychology text--a vigorous use of the book in our teaching could do much to benefit the dissemination of behavior analysis.  相似文献
