Positive Effects of Imagery on Police Officers' Shooting Performance under Threat

We investigated the effects of imagery on police officers' shooting performance under threat. To this end, 66 officers executed a realistic shooting exercise against an opponent that initially did not shoot back with painful coloured‐soap cartridges (low‐threat condition) followed by a condition in which he did [high‐threat (HT) condition]. In between conditions, participants performed an imagery intervention: one group imagined ‘successful shot execution’ and one imagined ‘successful shot execution under threat, including the accompanying emotions’; a control group received no imagery intervention. Although for the control group shot accuracy was significantly lower in the HT condition than under low‐threat conditions, both imagery groups were able to maintain their shot accuracy in the HT condition, despite increased levels of anxiety. It is concluded that focusing on successful shot execution is pivotal, whereas adding emotional statements does not seem to have an additional positive effect.

Was sagen „objektive“ Messverfahren über Sexualstraftäter?

A great deal of effort has been made to use so-called objective measurements in men convicted of child sexual abuse in recent years. The aim of using these procedures is to measure sexual preference for children more effectively while being less vulnerable for deception and to add information to subjective reports. In this paper it was investigated why research activities in this area have increased and what so-called “objective” measurements can reveal about sexual offenders. This article will discuss possible pros and cons of the use of such procedures for forensic court reports or in the context of therapy in a forensic setting.     

Application of the Copenhagen Soccer Test in high-level women players – locomotor activities,physiological response and sprint performance

We evaluated the physiological response, sprint performance and technical ability in various phases of the Copenhagen Soccer Test for Women (CSTw) and investigated whether the locomotor activities of the CSTw were comparable to competitive match-play (CM). Physiological measurements and physical/technical assessments were performed during CSTw for eleven Norwegian high-level women soccer players. The activity pattern during CSTw and CM was monitored using the ZXY tracking system. No differences were observed between CSTw and CM with regards to total distance covered (10093 ± 94 and 9674 ± 191 m), high intensity running (1278 ± 67 and 1193 ± 115 m) or sprinting (422 ± 55 and 372 ± 46 m) (p > .05). During CSTw, average HR was 85 ± 2%HRmax with 35 ± 2% playing time >90%HRmax. Blood lactate increased (p < .05) from 1.4 ± 0.3 mM at rest to an average of 4.7 ± 0.5 mM during CSTw, with no changes during the test. Blood glucose was 5.4 ± 0.3 mM at rest and remained unaltered during CSTw. Sprint performance (2 × 20 m) decreased (p < .05) by 3% during CSTw (8.19 ± 0.06–8.47 ± 0.10 s). In conclusion, the locomotor activities during CSTw were comparable to that of high-level competitive match-play. The physiological demands of the CSTw were high, with no changes in heart rate, blood lactate or technical performance during the test, but a lowered sprint performance towards the end of the test.     

Freedom,emotion, and self‐subsistence

A set of basic static predicates, ‘in itself, ‘existing through itself, ‘free’, and others are taken to be (at least) extensionally equivalent, and some consequences are drawn in Parts A and ? of the paper. Part C introduces adequate causation and adequate conceiving as extensionally equivalent. The dynamism or activism of Spinoza is reflected in the reconstruction by equating action with causing, passion (passive emotion) with being caused. The relation between conceiving (understanding) and causing is narrowed down by introducing grasping (λαμβ?νω) as a basic epistemological term. Part D, ‘The road to freedom through active emotion’, introduces a system of grading with respect to the distinctions introduced in the foregoing, including ‘being in itself, ‘freedom’, etc. Active emotions are seen to represent transitions to a higher degree of freedom, the stronger and more active ones being the more conducive to rapid increase in degree of freedom. Elementary parts of the calculus of predicates are used in order to facilitate the survey of conceptual relations and to prove some theorems.     

Eye movements during recall of aversive memory decreases conditioned fear

Cognitive-behavioral therapy for anxiety disorders typically involves exposure to the conditioned stimulus (CS). Despite its status as an effective and primary treatment, many patients do not show clinical improvement or relapse. Contemporary learning theory suggests that treatment may be optimized by adding techniques that aim at revaluating the aversive consequence (US) of the feared stimulus. This study tested whether US devaluation via a dual task – imagining the US while making eye movements – decreases conditioned fear. Following fear acquisition one group recalled the US while making eye movements (EM) and one group merely recalled the US (RO). Next, during a test phase, all participants were re-presented the CSs. Dual tasking, relative to the control condition, decreased memory vividness and emotionality. Moreover, only in the dual task condition reductions were observed in self-reported fear, US expectancy, and CS unpleasantness, but not in skin conductance responses. Findings provide the first evidence that the dual task decreases conditioned fear and suggest it may be a valuable addition to exposure therapy.     

Psychological Hardiness Predicts Success in a Norwegian Armed Forces Border Patrol Selection Course

The present study investigates the effects of psychological hardiness and successful completion of a rigorous 250‐km ski march over 9 days in Arctic winter conditions. This ski march is the final portion of a selection program for border rangers in the Norwegian Armed Forces. Study participants were N = 178 soldiers with a mean age of 19.9 years (range 18–23). Hierarchical regression results showed that successful completion of the ski march was predicted by total hardiness scores, after controlling for nutrition factors, physical fitness and sensation seeking. A second hierarchical regression found that the commitment facet of hardiness was the most significant predictor of ski march success, again controlling for nutrition, physical fitness and sensation seeking. Analyses of daily participant surveys showed that the high commitment group reported the highest levels of positive daily coping, and also evaluated their performance more positively. This group also showed increasingly positive self‐evaluations as the exercise went on. Together, these results indicate that hardiness commitment is a key factor influencing performance in a rigorous and stressful endurance task requiring sustained effort, perhaps by enhancing active coping skills and self‐efficacy beliefs.     

Emotion regulates attention: The relation between facial configurations,facial emotion,and visual attention

We used threatening, friendly, and neutral schematic facial stimuli, in which three, two, or one feature(s) conveyed emotion, to test the hypothesis that humans preferentially orient attention towards threat, and to examine the relation between facial features, emotional impression, and visual attention. Using a visual search paradigm, participants searched for discrepant faces in arrays of otherwise identical faces. Subsequently they also rated their emotional impression of the involved stimuli. Across four experiments, we found faster and more accurate detection of threatening than friendly faces, even when only one feature conveyed the emotion. Facial features affected both attention and emotion in the rank order eyebrows > mouth > eyes. Finally, the emotional impression of a face predicted its effect on attention.     

Cooperation or Isolation? Muslim Congregations in a Scandinavian Welfare State: A Nationally Representative Survey from Sweden

In the Scandinavian welfare context, the emphasis on cooperation between public authorities and the nonprofit sector continues to be a central institutional characteristic. But to what extent have the new Muslim congregations adapted to the Scandinavian tradition of organizational cooperation, and what circumstances—internal or external to these organizations—promote or disrupt the development of such cooperation? This study is based on a nationwide survey of local Muslim congregations in Sweden (n = 105). No support was found for the widespread notion that European Muslim congregations tend to exist as separate enclaves. The powerful discursive emphasis on organizational cooperation in Scandinavia creates vital opportunity structures, but local variations in demographic and socioeconomic conditions also seem to have an impact. Among internal factors that influence willingness to cooperate is not least the degree of ethnic heterogeneity; openness to different Muslim traditions—a precondition for a multiethnic congregation—is seen to correspond to a greater openness to the wider society.     

From ecology to ecosophy,from science to wisdom

Eco‐science (ecology) is not enough. Eco‐wisdom (ecosophy) is needed: How to live on Earth enjoying and respecting the full richness and diversity of life‐forms of the ecosphere.

The cold acknowledgement of dependency upon ecosystems is not enough to motivate responsible policies. To replenish the Earth, we need thejoy of interaction with life and within life. This implies deep reaction against the narrowly utilitarian outlook. We need integration of all levels: abstract and fundamental premises of a philosophy or religion, the derivation of general guideline of global action from these premises, and the conclusion of particular decisions in concrete situations in everyday life. In short: ecosophical total views are called for.     

Effector dynamics of rhythmic wrist activity and its implications for (modeling) bimanual coordination

To examine the role of the effector dynamics of the wrist in the production of rhythmic motor activity, we estimated the phase shifts between the EMG and the task-related output for a rhythmic isometric torque production task and an oscillatory movement, and found a substantial difference (45-52 degrees) between the two. For both tasks, the relation between EMG and task-related output (torque or displacement) was adequately reproduced with a physiologically motivated musculoskeletal model. The model simulations demonstrated the importance of the contribution of passive structures to the overall dynamics and provided an account for the observed phase shifts in the dynamic task. Additional simulations of the musculoskeletal model with added load suggested that particular changes in the phase relation between EMG and movement may follow largely from the intrinsic muscle dynamics, rather than being the result of adaptations in the neural control of joint stiffness. The implications of these results are discussed in relation to (models of) interlimb coordination in rhythmic tasks.
