Comparative assessment of the behaviour of drivers with Mild Cognitive Impairment or Alzheimer’s disease in different road and traffic conditions

The objective of this research was the analysis of the driving performance of drivers with Mild Cognitive Impairment (MCI) or Alzheimer’s disease (AD), in different road and traffic conditions, on the basis of a driving simulator experiment. In this experiment, healthy “control” drivers, patients with MCI, and patients with AD, drove at several scenarios at the simulator, after a thorough neurological and neuropsychological assessment. The scenarios include driving in rural and urban areas in low and high traffic volumes. The driving performance of healthy and impaired drivers was analysed and compared by means of Repeated Measures General Linear Modelling techniques. A sample of 75 participants was analysed, out of which 23 were MCI patients and 14 were AD patients. Various driving performance measures were examined, including longitudinal and lateral control measures. The results suggest that the two examined cerebral diseases do affect driving performance, and there were common driving patterns for both cerebral diseases, as well as particular characteristics of specific pathologies. More specifically, cognitively impaired drivers drive at lower speeds and with larger headway compared to healthy drivers. Moreover, they appear to have difficulties in positioning the vehicle on the lane. The group of patients had difficulties in all road and traffic environments, and especially when traffic volume was high. Most importantly, both cerebral diseases appear to significantly impair reaction times at incidents. The results of this research suggest that compensatory behaviours developed by impaired drivers are not adequate to counterbalance the direct effects of these cerebral diseases on driving skills. They also demonstrate that driving impairments increase as cognitive impairments become more severe (from MCI to AD).     

Possible selves in patients with right- versus left-onset Parkinson’s disease

Possible selves can be used to self-regulate and guide behavior towards what is desired to be achieved or avoided in life. Previous work suggests laterality effects exist within the brain regarding approach and avoidance systems to achieve self-regulation. A modified version of the possible selves task was administered to 45 patients with PD (22 right-onset and 23 left-onset) and 25 community dwelling control subjects (CS). Only 11.1% of patients exhibited balance among their hoped-for and feared possible selves versus 28% of CS. More right-onset patients used a promotion strategy whereas more left-onset patients used a prevention strategy. Patients with left-onset PD thought more about their feared selves, exhibiting reduced goal-directed behavior. Findings among the left-onset group indicate relative dependence of self-regulation on right-sided avoidance brain systems. This may point to an inability to move away from negative outcomes and to work towards rewarding outcomes, which could affect psychological health.     

Dysexecutive syndrome in Parkinson’s disease: the GREFEX study

The objectives of this study were to characterize the frequencies and profiles of behavioral and cognitive dysexecutive syndromes in PD (based on validated battery and diagnostic criteria) and to develop a shortened diagnostic battery. Eighty-eight non-demented patients with a diagnosis of PD were examined with an executive validated battery. Using a validated framework, the patients’ test results were interpreted with respect to normative data from 780 controls. A dysexecutive syndrome was observed in 80.6% of the patients [95% confidence interval: 71.1–90.1]. The dysexecutive profile was characterized by prominent impairments in deduction, flexibility, inhibition and initiation in the cognitive domain, and by global hypoactivity with apathy and hyperactivity in the behavioral domain. This finding implies that patients with PD should be assessed with cognitive tests and a validated inventory for behavioral dysexecutive syndromes. A shortened battery (based on three cognitive tests and three behavioral domains) provided high diagnostic accuracy.     

Pierre De Bérulle (1575–1629) and the renewal of Catholic spiritual life in France

Pierre de Bérulle, founder of the Oratoire de Jésus (commonly known as the Oratoire de France), is a leading figure in the renewal of the Catholic Church in France in the first half of the seventeenth century. He is generally regarded as the founder of the French School of Spirituality (École française de spiritualité), though this term has been much criticised in recent years. He is often described as a ‘reformer’ of the Church in France, but this is a half-truth which obscures his real originality; he certainly shared the aims of those striving to create a clergy which would be better educated, more morally upright and more pastorally sensitive and zealous; but above all else he was concerned with the spiritual renewal of the clergy and with the Church in France generally. Lastly, he has often been accused of wishing to create chiefly, if not exclusively, a spirituality of the priesthood and to work for the ‘sanctification’ of the clergy. But his work and ideas must be seen here in a broader perspective, for Bérulle and his disciples shared with St Francis de Sales the aim, expressed in his Introduction à la vie devote (1608), of creating and promoting a spirituality available to all Christians. This article examines his conception of the Oratory, which he intended to be an intermediary between the religious orders and the secular clergy, his spiritual theology, what I have called his ‘spiritual pedagogy’, and his influence in France and elsewhere.     

Aging,memory loss,and Alzheimer’s disease: What do refugees from the former Soviet Union think?

ABSTRACT

Since the mid-1970s, approximately 700,000 émigrés from the former Soviet Union (FSU), most of Jewish descent, settled in the United States. Now, 25 or more years post-emigration, they have “aged in place” in the United States, but their values, beliefs, and attitudes about growing old, memory changes, and Alzheimer’s disease remain grounded in their earlier life experiences. Based on findings from a study of the social and cultural factors affecting beliefs about Alzheimer’s disease, aging, and memory loss, this article examines how past life experiences, the immigration experience, and cultural values affect Russian-speaking refugees’ beliefs and views about aging, memory loss, and Alzheimer’s disease.     

心理资本: 本土量表的开发及中西比较

开发了本土心理资本量表, 并将之与西方量表进行了比较。结果显示, 本土心理资本构念具有二阶双因素结构: 事务型心理资本(自信勇敢、乐观希望、奋发进取与坚韧顽强)与人际型心理资本(谦虚诚稳、包容宽恕、尊敬礼让与感恩奉献)。事务型心理资本与西方心理资本基本相似, 人际型心理资本则具有本土文化气息。本土量表具有良好的效标关联效度, 人际型心理资本、事务型心理资本和任务绩效、周边绩效、工作满意度、工作投入及组织承诺显著正相关, 人际型心理资本与传统性、相依我正向关系显著。相比西方量表, 本土量表的信效度更好, 对工作绩效有更强的解释能力, 尤其是对周边绩效。建议进行心理资本研究时应充分考虑中西文化差异, 对组织而言, 则应重视对雇员本土心理资本各要素的开发与管理。     

创业人格研究述评

创业领域的人格研究在经过了繁荣发展后, 于20世纪90年代受到了广泛的批评。本文在简要介绍了创业人格的研究历程后, 首先介绍了创业者人格特征与成功模型, 然后总结了创业研究中的具体人格特质和一般人格特质, 并从概念、样本、工具等六个方面分析了这类研究受到广泛质疑的原因, 最后指出了创业人格研究的四个努力方向：(1)创业内涵的界定和理论模型的建构; (2)研究设计和测量的改进; (3)调节与中介变量的考察; (4)创业绩效变量的更细致区分。
