Explaining the effects of a decision intervention on mammography intentions: The roles of worry,fear and perceived susceptibility to breast cancer

Objective: This study examines the effects of a mammography decision intervention on perceived susceptibility to breast cancer (PSBC) and emotion and investigates how these outcomes predict mammography intentions.

Design: Randomised between-subjects online experiment. Participants were stratified into two levels of risk. Within each stratum, conditions included a basic information condition and six decision intervention conditions that included personalised risk estimates and varied according to a 2 (amount of information: brief vs. extended) × 3 (format: expository vs. untailored exemplar vs. tailored exemplar) design. Participants included 2465 US women ages 35–49.

Main Outcome Measures: PSBC as a percentage, PSBC as a frequency, worry, fear and mammography intentions.

Results: The intervention resulted in significant reductions in PSBC as a percentage for women in both strata and significant increases in worry and fear for women in the upper risk stratum. Of the possible mediators examined, only PSBC as a percentage was a consistent mediator of the effect of the intervention on mammography intentions.

Conclusion: The results provide insight into the mechanism of action of the intervention by showing that PSBC mediated the effects of the intervention on mammography intentions.     

Learning to avoid spiders: fear predicts performance,not competence

We used an immersive virtual environment to examine avoidance learning in spider-fearful participants. In 3 experiments, participants were asked to repeatedly lift one of 3 virtual boxes, under which either a toy car or a spider appeared and then approached the participant. Participants were not told that the probability of encountering a spider differed across boxes. When the difference was large (Exps. 1 and 2), spider-fearfuls learned to avoid spiders by lifting the few-spiders-box more often and the many-spiders-box less often than non-fearful controls did. However, they hardly managed to do so when the probability differences were small (Exp. 3), and they did not escape from threat more quickly (Exp. 2). In contrast to the observed performance differences, spider-fearfuls and non-fearfuls showed equal competence, that is comparable post-experimental knowledge about the probability to encounter spiders under the 3 boxes. The limitations and implications of the present study are discussed.     

催产素影响恐惧习得和消退的认知神经机制

恐惧是一种基本的情绪, 在人类的生存和适应中发挥着重要作用。先前的研究表明, 杏仁核、背侧前扣带回、脑岛等脑区是条件化恐惧习得的认知神经基础, 杏仁核、海马和腹内侧前额叶等脑区在恐惧消退过程中发挥重要作用。研究发现, 催产素与恐惧习得和恐惧消退过程密切相关。恐惧习得过程中, 催产素影响杏仁核、背侧前扣带回的活动, 影响杏仁核与背侧前扣带回和脑干间的功能连接, 促进或抑制恐惧习得过程; 恐惧消退过程中, 催产素影响了杏仁核和腹内侧前额叶的活动, 并且影响杏仁核与内侧前额叶和海马间的功能连接, 促进或抑制恐惧消退过程。未来研究应从性别差异、神经网络模型、身心发育和病理研究等角度展开, 力图深入理解催产素影响恐惧情绪加工的认知神经机制。     

Ill-health in Sweden 2005: Discontent in a modern welfare society and its relation to globalization

Abstract

The growing ill-health in Sweden is related to the crisis of the welfare state and to globalization and the expansion of a new virtual reality affecting the conceptualization of time and space, as well as to wider areas of human interaction, thinking, and ethical judgment. Fear and anxiety are emotional states of mind that have widespread effects on an individual level as well as on the whole of society.     

Differential response patterns to disgust-related pictures

ABSTRACT

In the present study, attentional bias was investigated as a potential predisposing mechanism for the contamination-related subtype of obsessive-compulsive disorder (C-OC disorder). Fifty healthy participants with varying degrees of subclinical C-OC symptoms performed a visual search task to measure differential attentional biases elicited by neutral, disgust-, and fear-specific pictorial material. Participants had to find a target picture within five neutral distractor pictures randomly presented on different locations in an array. The task was to decide whether the array contained an unpleasant target picture or not. In randomly-selected emotional trials, participants were further asked about the content of the picture and the confidence of their answer. The results show that the reaction times significantly differed between the emotional and neutral pictures. Participants were significantly more confident in answering questions referring to fear compared to disgust pictures. This effect was marginally amplified in participants with higher C-OC symptoms. We discuss the results within the framework of the cost and benefit hypothesis, which postulates that disgust evolutionarily elicits stronger uncertainty compared to fear, owing to the ambiguous nature of the stimuli. Increased uncertainty might be an important but underestimated factor for pathological disgust experience, such as in obsessive-compulsive disorder.     

Psychophysiological and subjective indices of emotion as a function of age and gender

Old, middle-aged and young persons of both genders were presented with slides containing pictorial stimuli that varied in emotional content. Each picture was rated on three dimensions: (1) valence; (2) arousal; and (3) dominance, using a 25-point scale. Heart rate, skin conductance, and forehead and cheek EMG were recorded during each slide presentation. The old and middle-aged groups showed greatly attenuated psychophysiological responses, compared to the young group. However, the old and middle-aged subjects used more extreme ratings than the young subjects on both the valence and arousal dimensions. Females were more valence-sensitive than males, but males in general used more extreme ratings of arousal than females. These results suggest a tendency to report increased felt emotion but decreased physiological response to emotional stimuli across the life span.     

Direct and indirect measures of spider fear predict unique variance in children's fear-related behaviour

This study investigated whether direct and indirect measures predict unique variance components of fearful behaviour in children. One hundred eighty-nine children aged between 9 and 12 performed a pictorial version of the emotional Stroop task (EST), filled out the Spider Anxiety and Disgust Screening for Children (SADS-C), the Spider Phobia Questionnaire for Children (SPQ-C), and took part in a Behavioural Assessment Test (BAT). The EST did not correlate with self-reports. Correlations of the self-reports and the BAT remained significant after partialling out EST performance. Likewise, the EST and the BAT still correlated significantly with each other when controlling for the self-reports. This indicates that both direct and indirect measures are useful for predicting unique variance components of fearful behaviour in children. Moreover, it may explain why some previous studies have not found a relationship between self-reported fear and EST performance.     

Touch,enjoyment and health: In infancy

The paper explores Peter Lomas's influence on the author as a therapist, and in particular his idea that therapy is inescapably an ethical endeavour, however much we try to avoid this. Less persuasive, however, is Lomas's belief in therapy as a moral influence. The author sees it more as an ethical space (after Roger Poole) where people can feel free to explore, without judgement, the difficulties that have brought them there - despair, loss, inauthenticity, unfulfilled lives. The paper also explores R.D. Laing's idea of ‘fear of the soul’ which afflicts therapists (including those who do not hold much with ideas of technique) - despite our title - as well as many of those who come to see us. This fear is, it is argued, understandable as it takes us into uncharted waters, a minefield. In other words, therapy can be dangerous. The paper draws both on the author's work with individuals, and in the Philadelphia Association's community house, with which he has been involved for many years.     

The Effects of Instructor Fear Appeals and Moral Appeals on Cheating-Related Attitudes and Behavior of University Students

Little attention has been paid in academic dishonesty literature to empirically testing the effectiveness of different instructor communication strategies to minimize cheating. Using a quasi-experimental design, we compared the effectiveness of instructor fear appeals and moral appeals on student cheating-related attitudes and behavior. Cheating was most strongly associated with neutralizing attitudes in the moral appeal condition. Also, the relationship between observation of others cheating and self-reported cheating behaviors was stronger in both treatment conditions than in the control condition. Although a trend toward less cheating in the treatment conditions was evident, it did not attain statistical significance.     

Is Fear of Crime Mainly Social and Economic Insecurity in Disguise? A Multilevel Multinational Analysis

Using the 2006 Eurobarometer data (representative sample of the European population, N = 16 306, 27 countries), we performed a multilevel analysis aimed at predicting fear of crime. A significant proportion of the variation in fear of crime was at country level. Of the individual predictors included, being a woman, being poorly educated, being unemployed, and being an urban dweller showed positive relations with fear of crime. Fear was highest among people who considered themselves to be socially marginal, among people with negative expectations regarding themselves and their country's future, and among people who considered their nation's welfare system to be unsatisfactory. Among the ecological predictors we took into consideration, nations' degree of economic inequality and low expenditure on education and on social protection showed a positive association with fear of crime, whereas the crime, immigration, and employment rates did not. Implications and limitations of this research are discussed. Copyright © 2013 John Wiley & Sons, Ltd.
