Phobic anxiety in 11 nations. Part I: Dimensional constancy of the five-factor model

The Fear Survey Schedule-III (FSS-III) was administered to a total of 5491 students in Australia, East Germany, Great Britain, Greece, Guatemala, Hungary, Italy, Japan, Spain, Sweden, and Venezuela, and submitted to the multiple group method of confirmatory analysis (MGM) in order to determine the cross-national dimensional constancy of the five-factor model of self-assessed fears originally established in Dutch, British, and Canadian samples. The model comprises fears of bodily injury-illness-death, agoraphobic fears, social fears, fears of sexual and aggressive scenes, and harmless animals fears. Close correspondence between the factors was demonstrated across national samples. In each country, the corresponding scales were internally consistent, were intercorrelated at magnitudes comparable to those yielded in the original samples, and yielded (in 93% of the total number of 55 comparisons) sex differences in line with the usual finding (higher scores for females). In each country, the relatively largest sex differences were obtained on harmless animals fears. The organization of self-assessed fears is sufficiently similar across nations to warrant the use of the same weight matrix (scoring key) for the FSS-III in the different countries and to make cross-national comparisons feasible. This opens the way to further studies that attempt to predict (on an a priori basis) cross-national variations in fear levels with dimensions of national cultures.     

Deduction chains for common knowledge

Deduction chains represent a syntactic and in a certain sense constructive method for proving completeness of a formal system. Given a formula , the deduction chains of are built up by systematically decomposing into its subformulae. In the case where is a valid formula, the decomposition yields a (usually cut-free) proof of . If is not valid, the decomposition produces a countermodel for . In the current paper, we extend this technique to a semiformal system for the Logic of Common Knowledge. The presence of fixed point constructs in this logic leads to potentially infinite-length deduction chains of a non-valid formula, in which case fairness of decomposition requires special attention. An adequate order of decomposition also plays an important role in the reconstruction of the proof of a valid formula from the set of its deduction chains.     

Coping with the stress of a painful medical procedure

To evaluate its effect on procedure-related distress, the focus of attention was manipulated by providing training to hospitalized acute burn patients (n=42). Participants were randomly assigned to attention focusing (i.e. attending to procedural sensations) or music distraction (i.e. attention diverting) coping interventions, or to usual care during the target dressing change. Coping behavior (i.e. distraction, focusing, and three confounding methods, ignoring, catastrophizing, reinterpreting), tension and intrusiveness were evaluated 24 h retrospectively (i.e. for the prior procedure), during the targeted procedure, and 30 min after the target procedure. When coping during the target procedure by ignoring, reinterpreting, and catastrophizing were covaried, the music distraction group experienced significantly fewer intrusions, and the attention focus group had more intrusions. Additionally, secondary analyses revealed that coping by ignoring during the prior day's procedure significantly predicted higher procedural tension during, and more intrusions following, the targeted procedure. Suppression-based forms of emotion-focused coping may be enhanced by training in the use of an explicit distractor.     

Positive maternal interaction behavior moderates the relation between maternal anxiety and infant regulatory problems

Regulatory problems in infancy are determined by different risk factors. This study aims to examine how psychosocial risk factors are connected, and how they impact the early regulatory ability of 3-month-old infants. In a sample of 57 mother–infant dyads, maternal anxiety and infant crying, sleeping and feeding habits were assessed. As a possible moderator, the role of positive maternal behavior was analyzed by videotaping face-to-face interactions. During the interaction, interactive stress was provoked with the face-to-face still-face paradigm (FFSF). Thus, this study differentiated between the effects of maternal behavior in both an ordinary play context, as well as a stressful interaction context. Results revealed that the relation between maternal anxiety and infant regulatory problems in crying and sleeping varied as a function of positive maternal engagement in stressful situations. However, a significant moderation effect influencing infant feeding problems could not be demonstrated. These findings stress the importance of positive maternal interaction behavior in at least some parts of regulatory adjustment of at-risk infants.     

Holistic processing improves change detection but impairs change identification

It has been just over a century since Gestalt psychologists described the factors that contribute to the holistic processing of visually presented stimuli. Recent research indicates that holistic processing may come at a cost; specifically, the perception of holistic forms may reduce the visibility of constituent parts. In the present experiment, we examined change detection and change identification accuracy with Kanizsa rectangle patterns that were arranged to either form a Gestalt whole or not. Results from an experiment with 62 participants support this trade-off in processing holistic forms. Holistic processing improved the detection of change but obstructed its identification. Results are discussed in terms of both their theoretical significance and their application in areas ranging from baggage screening and the detection of changes in radiological images to the systems that are used to generate composite images of perpetrators on the basis of eyewitness reports.     

Attention modification in persons with fibromyalgia: a double blind, randomized clinical trial

Contemporary models of chronic musculoskeletal pain emphasize the critical roles of fear, anxiety, and avoidance as well as biases in attention in the development and maintenance of chronic pain disability. Evidence supports the influence of individual difference variables such as anxiety sensitivity, pain-related anxiety, and catastrophizing on the pain experience and on pain-related attentional biases. Changes in attentional biases have been associated with treatment gains in patients with clinically significant anxiety. The Attentional Modification Paradigm (AMP) is a modification of the dot-probe paradigm used to facilitate such changes in attentional biases. Given the relationship between chronic musculoskeletal pain and anxiety, AMP may be effective in reducing pain as well. Participants included persons (n = 17) with fibromyalgia and were randomly assigned to either an AMP condition or a control condition. The participants completed two 15-minute AMP sessions per week for 4 weeks. Those in the AMP condition reported statistically significant and substantial reductions on several individual difference variables relative to those in the control condition, and a greater proportion experienced clinically significant reductions in pain. These preliminary results offer a promising new avenue for treating chronic musculoskeletal pain that warrants additional research. Comprehensive results, limitations, and future directions are discussed.
