Application of Cognitive Load Theory to Develop a Measure of Team Cognitive Efficiency

Improving human systems integration through technologically advanced training and performance aids has become increasingly important to military transformation. Measures of improved cognitive and coordination processes arising from the employment of transformational tools are necessary to guide the refinement and future development of such technologies. In this article, we describe a cognitive load theory approach to developing a combinatory measure of individual workload and team performance following an experimental intervention involving training and a decision support system. We discuss how indicators of what we term team cognitive efficiency can improve assessing the effectiveness of transformational processes and technologies.     

Executive functions and social skills in survivors of pediatric brain tumor

Medical advances have resulted in increased survival rates for children with brain tumors. Consequently, issues related to survivorship have become more critical. The use of multimodal treatment, in particular cranial radiation therapy, has been associated with subsequent cognitive decline. Specifically, deficits in executive functions have been reported in survivors of various types of pediatric brain tumor. Survivors are left with difficulties, particularly in self-monitoring, initiation, inhibition, and planning, to name a few. Another domain in which survivors of pediatric brain tumor have been reported to show difficulty is that of social skills. Parents, teachers, and survivors themselves have reported decreased social functioning following treatment. Deficits in executive functions and social skills are likely interrelated in this population, as executive skills are needed to navigate various aspects of social interaction; however, this has yet to be studied empirically. Twenty-four survivors of pediatric brain tumor were assessed using a computerized task of executive functions, as well as paper-and-pencil measures of social skills and real-world executive skills. Social functioning was related to a specific aspect of executive functions, that is, the survivors' variability in response time, such that inconsistent responding was associated with better parent-reported and survivor-reported social skills, independent of intellectual abilities. Additionally, parent-reported real-world global executive abilities predicted parent-reported social skills. The implications of these findings for social skills interventions and future research are discussed.     

Identity,coping style,and health behaviour among first generation Irish immigrants in England

Abstract

Berry's (1997) framework for acculturation research was used to explore the relationship between identity and health among Irish immigrants in England. One hundred and twelve first generation Irish immigrants completed questionnaire measures of ethnic identity, opportunities for identity expression, generalised coping style, and health behaviour. Significant, though small, positive correlations were observed between identity and health behaviour as predicted. Regression analyses and path analysis were used to present a model of the link between variables. Of particular note were the contrasting ways in which the two dimensions of identity were associated with health behaviour. Participants who positively evaluated their ethnic origins reported engaging in healthier behaviour and adopting more beneficial coping strategies when faced with day-to-day stresses and problems. Participants who reported their ethnic origin as more central to their overall identity were also more likely to adopt beneficial coping strategies. Concomitantly, however, they had fewer than desired opportunities for expressing their ethnic identity which was, in turn, associated with less beneficial coping and health behaviour. In looking for ways to tackle the well-documented health problems of both first and second generation Irish in England, the results suggest that encouragement to feel more positive about their ethnic identity might result in greater usage of behavioural approach coping and, relatedly, to improved health behaviour.     

Uncertainty in ethical consumer choice: a conceptual model

The market place has seen significant growth in the demand for ‘ethical’ products and services. Yet, consumers often experience knowledge, evaluation and choice uncertainties in decision‐making processes, particularly in relation to products such as ethical clothing. The authors explore this pertinent form of consumer uncertainty through three qualitative studies of ethical consumers that examine their approaches to clothing consumption. In‐depth interviews and focus groups confirm uncertainty arises; the results also identify the causes and consequences of consumer uncertainty in this context. The causes of uncertainty pertain to issues surrounding complexity, ambiguity, conflict and credibility that give rise to uncertainties that result in delaying purchase decisions, compromising beliefs and negative emotions. This study contributes to literature by offering a holistic understanding of the challenges facing consumers when making ethical choices. Copyright © 2013 John Wiley & Sons, Ltd.     

Brief treatment with alprazolam and behavioral guidance in panic disorder

Abstract

Thirty-two patients with panic disorder, with or without agoraphobic limitations, were treated with alprazolam (mean dose 3.5 mg/d) plus brief behavioral guidance in an open study during eight weeks. The sample had a notorious severity in the frequency of panics and phobic avoidance but was only mildly depressed. Before starting treatment the presence of demoralized mood and extensive avoidance were significant indicators of clinical severity, whereas the presence of dizziness as a relevant somatic complaint was not related to higher severity. After eight weeks of treatment a clinical improvement equal to or exceeding 80% of change was obtained in all cases (29) who completed treatment. Ninety-two percent of the patients were panic free at the end of treatment. There were significant reductions in all the scales with comparable declines in the subgroups formed according to the presence or absence of agoraphobic avoidance and demoralization. The data suggested that moderate doses of alprazolam could be a quick and effective treatment for panic-agoraphobic patients in the short term. The behavioral guidance probably helped in reducing agoraphobic avoidance and in obtaining global good effectiveness although this awaits controlled tests. Finally, the similarity in the response to treatment regardless of the presence of extensive avoidance or demoralized mood argues in favor of not considering the different variants of panic-agoraphobic syndrome differently, at least in samples with similar severity to the present one.     

How people think “if only …” about reasons for actions

When people think about how a situation might have turned out differently, they tend to imagine counterfactual alternatives to their actions. We report the results of three experiments which show that people imagine alternatives to actions differently when they know about a reason for the action. The first experiment (n = 36) compared reason – action sequences to cause – effect sequences. It showed that people do not imagine alternatives to reasons in the way they imagine alternatives to causes: they imagine an alternative to an action more than an effect, and to a cause more than a reason. The second experiment (n = 214) and the third experiment (n = 190) both show that different sorts of reasons have different sorts of effects on how people imagine alternatives to actions. People imagine an alternative to an action (the protagonist went to a ball) less often when they know the reason for the action was an obligation (he had to participate in fundraising) compared to when they know about a weaker reason (he wanted to meet a famous violinist) or no reason. The second experiment shows the effect for a social obligation and the third experiment replicates and extends it to a health obligation. We interpret the results in terms of the possibilities that people keep in mind about actions and their reasons.
