Package Graphics and Consumer Product Beliefs

In recent years, marketers' tactics to increase product sales through health claims have been scrutinized by public policy makers. The culmination of this process was the passage of the National Labeling Education Act, which highly restricts the type, amount, and format of nutritional information conveyed on the package. In this investigation, we examine an under-explored aspect of the package—its colors and pictures—to determine what, if any, impact these aspects have on consumer beliefs regarding important product characteristics. We find that even when very concrete verbal information is used, graphical representations have a significant and long-term effect on product beliefs and purchase intentions.     

Pain: Biopsychosocial Mechanisms and Management

Traditionally, pain has been viewed as a sensory event warning of tissue damage or illness. This explanation fails to account for many of the experiences of people suffering from clinically painful conditions. Over the past two decades, a new biopsychosocial perspective on pain has emerged. This perspective emphasizes that pain is a dynamic process that not only is influenced by biological, psychological, and social mechanisms of pain, but also produces biological, psychological, and social changes that can affect future responses to pain. This review presents findings from recent studies of the biological, psychological, and social mechanisms of pain and discusses the implications of these findings for pain research, assessment, prevention, and treatment, as well as for health care policy.     

Psychological Factors Associated with Emotional Responses to Receiving Genetic Risk Information

This study identified levels of distress, and predictors of levels of distress, in women undergoing assessment for genetic risk of breast/ovarian cancer based on their family history. It comprised a cohort study following 154 women who completed questionnaires at entry into a cancer genetic assessment programme and following risk provision. Independent significant associates of anxiety following risk provision were age, neuroticism, feeling hopeless about developing cancer, a perceived lack of control over developing cancer, lack of a social confidant, and a coping response involving acceptance/resignation. Depression was associated with age, neuroticism, feeling hopeless about developing cancer, lack of social confidant, and a coping response involving acceptance/resignation. To avoid high levels of psychological morbidity in future cohorts undergoing cancer genetic risk assessment, information should be given that emphasises that some degree of control over health outcomes through behaviour change or increased surveillance is possible.     

The effectiveness of function‐based interventions to treat sleep problems,including unwanted co‐sleeping,in children with autism

This study investigated the effectiveness of functional behavioral assessment (FBA)—informed interventions for sleep problems, particularly co‐sleeping, in children with autism spectrum disorder (ASD). Seven children, who exhibited multiple sleep problems including unwanted co‐sleeping, participated. FBA, based on information derived from interviews and parent‐recorded sleep diaries, was used to develop individualized case formulations upon which multicomponent, parent‐implemented interventions were based. These were evaluated using a single‐case, non‐concurrent multiple‐baseline‐across‐participants design. Improvements were observed across all sleep problems, including the elimination of co‐sleeping. Gains were maintained at follow‐up for five out of seven children, though two children did not complete intervention. Parents reported high levels of satisfaction with the program. FBA‐based interventions for sleep problems in children with ASD and their clinical implications are further discussed.     

The effect of knowledge of mathematics on gambling behaviours and erroneous perceptions

This study evaluates the effect of knowledge of mathematics as a protective factor against excessive gambling behaviours and erroneous beliefs. Two groups with different levels of knowledge of mathematics were compared as to their perceptions and behaviours before and during a gambling session. A total of 60 participants (30 men, 30 women) completed a questionnaire evaluating how they perceive the notion of chance and participated in two experimental tasks: the production of a random sequence of heads/tails, and a gambling session on a video lottery terminal. The results show that participants with knowledge of mathematics held more erroneous perceptions of gambling before the experiment whereas both groups showed an equal number of erroneous perceptions and behaviours during gambling. The importance of knowledge of mathematics as a protective factor against excessive gambling is questionable. The theoretical and practical implications of these results are discussed with regard to the prevention of excessive gambling.     

I don't believe but I pray: spirituality,instrumentality, or paranormal belief?

These three studies are among the first to systematically compare five Chinese religious groups on intrinsic (spiritual) and extrinsic (instrumental and paranormal) orientation. In Study 1, a Chinese version of the Index of Core Spiritual Experiences was developed. In Studies 2 and 3, spirituality and religious involvement was found to be greatest among Christians, followed in order by Buddhists, Taoists, traditional nones, and other nones. An instrumental purpose for religious activities and paranormal belief was found to be highest among Taoists, followed in order by Buddhists, traditional nones, other nones, and Christians. The results are consistent with the conclusion that Christianity offers the least support for an extrinsic religious orientation and the most support for an intrinsic religious orientation.     

Do equilibrium constraints modulate postural reaction when viewing imbalance?

Action observation and action execution are tightly coupled on a neurophysiological and a behavioral level, such that visually perceiving an action can contaminate simultaneous and subsequent action execution. More specifically, observing a model in postural disequilibrium was shown to induce an increase in observers' body sway. Here we reciprocally questioned the role of observers' motor system in the contagion process by comparing participants' body sway when watching displays of antero-posterior vs. lateral imbalance. Indeed, during upright standing, biomechanical constraints differ along the antero-posterior (A-P) and medio-lateral (M-L) axes; hence an impact of observers' postural constraints on the contagion response would result in different reactions to both types of stimuli. In response to the displays, we recorded greater area of center of pressure (CoP) displacement when watching forward/backward compared to left/right imbalance. In addition, after normalizing A-P and M-L CoP displacements by a control condition (fixation cross), A-P CoP path length when viewing forward imbalance tended to be higher than M-L CoP path length when viewing imbalance to the left or right. These results indicate that postural contagion is promoted when the display is compatible with observers' motor stabilization strategy which is mainly oriented along the A-P axis. In terms of clinical application, this study brings new indications for adaptation of observational training devices in rehabilitation programs.     

Spouse and parent-offspring similarities in cardiovascular response to mental arithmetic and isometric hand-grip

Thirty spouse pairs were recruited for a stress protocol consisting of alternating stress and relaxation periods. Repeated measurements of blood pressure, heart rate, and blood volume pulse were obtained. Spouse pairs were parents of young adult sibling pairs who had previously participated in a slightly different version of the protocol. Although spouses exhibited some behavioral similarities, there were no significant similarities in cardiovascular response to stress. However, despite the fact that parents and their offspring were tested on different occasions using somewhat different procedures, some similarities in cardiovascular reactivity were observed. Significant parent-offspring similarities in heart-rate response to mental arithmetic and diastolic blood pressure response to isometric hand-grip were observed, as well as several behavioral similarities. Assortative mating and the nature of one's current home environment seem to be less important in the familial aggregation of cardiovascular reactivity to stress than early environmental and/or genetic factors.     

Analyse d'une Sepreuve d'image mentale chez des adolescents presentant des difficultis d'apprentissage scolaire1

Le travail faisant l'objet de cet article s'inscrit dans le cadre d'un programme de recherche plus large qui s'intéresse à la variabilité individuelle des processus cognitifs et à son influence éventuelle sur les lois générates du développement de l'intelligence. Une partie des résultats a déjàété présentée dans d'autres publications auxquelles le lecteur pourra se référer pour plus de détails (par exemple, Rieben et al., 1983). Nous nous contenterons de les décrire brièvement afin d'introduire l'aspect spécifique sur lequel nous nous sommes centrées ici.
