On avoiding framing effects in experienced decision makers

The present study aimed to (a) demonstrate the effect of positive–negative framing on experienced criminal justice decision makers, (b) examine the debiasing effect of visually structured risk messages, and (c) investigate whether risk perceptions mediate the debiasing effect of visual aids on decision making. In two phases, 60 senior police officers estimated the accuracy of a counterterrorism technique in identifying whether a known terror suspect poses an imminent danger and decided whether they would recommend the technique to policy makers. Officers also rated their confidence in this recommendation. When information about the effectiveness of the counterterrorism technique was presented in a numerical format, officers' perceptions of accuracy and recommendation decisions were susceptible to the framing effect: The technique was perceived to be more accurate and was more likely to be recommended when its effectiveness was presented in a positive than in a negative frame. However, when the information was represented visually using icon arrays, there were no such framing effects. Finally, perceptions of accuracy mediated the debiasing effect of visual aids on recommendation decisions. We offer potential explanations for the debiasing effect of visual aids and implications for communicating risk to experienced, professional decision makers.

Jus Ad Bellum,Values, and the Contemporary Structure of International Law

In “Religion, Violence, and Human Rights: Protection of Human Rights as Justification for the Use of Armed Force,” James Johnson discusses an important dilemma for contemporary society: when should transnational military force be permitted to protect human rights? Professor Johnson uses the relatively recent doctrine of a “responsibility to protect” as the centerpiece of his paper, characterizing it as a reaction to legal concepts that emerged in the “Westphalian system.” Yet the doctrine, at least as it relates to the use of military force, is not a reaction to that system but, rather, to the relatively recent system of the UN Charter, particularly its relegation to the Security Council of the exclusive authority to determine when military force should be used for purposes other than self‐defense. When the Cold War ended and the Security Council failed to act to protect human rights, the doctrine was born.     

Le momentum psychologique en sport : vers une perspective complexe et dynamique

Psychological momentum (PM) is a social phenomenon that has triggered the curiosity of sport psychologists since the early 1980s. From early to recent conceptualizations, PM has been considered as a complex construct, inherently related to variations in sport performance. Over the past 30 years, several models have been proposed to untangle how PM is triggered, which psychological changes are involved in PM experiences, and how PM relates to performance. While linear (causal) models have dominated past research on PM, researchers have recently found that PM can change nonlinearly, depending on the performance history of the competition. This systematic review aims to provide an overview of different PM models that have been proposed in the past to increase insights into the complexity of PM, including the transition from linear causal models to nonlinear dynamical models. Moreover, based on the current state of affairs, perspectives for future research are provided.     

Recent trends in cultural theories

Multiculturalism is probably the most important and most misunderstood psychological construct of this decade. This article identifies specific and uniquely valuable contributions of a multicultural perspective and demonstrates the importance of multicultural awareness training as a primary prevention strategy, directed toward preventing multicultural misunderstandings before they happen by training mental health providers to become more aware of their culturally learned assumptions and the contrasting cultural contexts of their clients. The development of recent multicultural theories will be reviewed to demonstrate how the definition of cultural theories have changed over time toward a broader and more complicated perspective. Finally practical applications of culture-centered theories will be reviewed through the presentation of a Cultural Grid for separating behaviors from expectations in each cultural context.     

Modular Organization of Exploratory Force Development Under Isometric Conditions in the Human Arm

Muscle coordination of isometric force production can be explained by a smaller number of modules. Variability in force output, however, is higher during exploratory/transient force development phases than force maintenance phase, and it is not clear whether the same modular structure underlies both phases. In this study, eight neurologically-intact adults isometrically performed target force matches in 54 directions at hands, and electromyographic (EMG) data from eight muscles were parsed into four sequential phases. Despite the varying degree of motor complexity across phases (significant between-phase differences in EMG-force correlation, angular errors, and between-force correlations), the number/composition of motor modules were found equivalent across phases, suggesting that the CNS systematically modulated activation of the same set of motor modules throughout sequential force development.     

Noninvasive brain stimulation over M1 and DLPFC cortex enhances the learning of bimanual isometric force control

Motor learning plays an important role in upper-limb function and the recovery of lost functionality. This study aimed to investigate the relative impact of transcranial direct current stimulation (tDCS) on learning in relation to the left primary motor cortex (M1) and left dorsolateral prefrontal cortex (DLPFC) during bimanual isometric force-control tasks performed with both hands under different task constraints. In a single-blind cross-over design, 20 right-handed participants were randomly assigned to either the M1 group (n = 10; mean age, 22.90 ± 1.66 years, mean ± standard deviation) or the DLPFC group (n = 10; mean age, 23.20 ± 1.54 years). Each participant received 30 min of tDCS (anodal or sham, applied randomly in two experiments) while performing the bimanual force control tasks. Anodal tDCS of the M1 improved the accuracy of maintenance and rhythmic alteration of force tasks, while anodal tDCS of the DLPFC improved only the maintenance of the force control tasks compared with sham tDCS. Hence, tDCS over the left M1 and DLPFC has a beneficial effect on the learning of bimanual force control.     

The Moderating Effect of Cognitive Flexibility in the Relationship Between Work Stress and Psychological Symptoms in Korean Air Force Pilots

Stress is closely associated with not only physical illness but also with indices of psychological maladjustment. However, such negative mental health outcomes may vary depending on the individual’s cognitive style, or perception of stress. Air force pilots are particularly vulnerable to experience a high degree of stress as they are required to conduct missions while simultaneously monitoring for safety in complex and uncertain flight situations. It can thus be posited that appropriate use of cognitive stress management strategies is one of the crucial competency requirements for pilots. As such, the present study examined the effects of stress on psychological symptoms of Korean Air Force pilots and further investigated the moderating role of cognitive flexibility in this relationship. A total of 192 air force pilots participated in the present study. The results indicated that degree of stress was positively correlated with indices of psychological maladjustment, while cognitive flexibility was negatively associated with psychological symptoms. Furthermore, cognitive flexibility demonstrated a significant moderating effect on the relationship between stress and psychological symptoms. Such results suggest that cognitive flexibility may serve as a protective factor in the potential effects of stress on psychological adjustment. Implications and suggestions for future research are discussed.
