驾驶员在交通场景中的变化视盲及其启示

变化视盲(change blindness)现象,也称变化盲,是指视觉情景中人们不能觉察到某个事物变化的现象。研究以驾驶员为主体探讨了道路交通领域中的变化视盲现象。首先,从场景变化特征和驾驶员特征两个方面综述了影响驾驶员变化视盲的影响因素;其次,结合影响因素与变化视盲的特征理论建立了驾驶员变化检测的认知过程模型;最后,在模型的基础上,讨论了提高驾驶员变化检测能力的实际意义和潜在措施,并对未来有关交通安全变化视盲的研究予以展望。     

运动中的效能期望、归因和情感反应的相关研究

运用Ｒｕｓｓｅｌｌ的归因维度量表等问卷对被试的效能期望、归因和情感反应进行相关研究，结果表明：效能期望影响着被试运动中的归因和情感反应；所测被试倾向于把运动结果归于个人可控的、不稳定的和内部的原因；归因能预测运动后的情感反应，但并非所有的归因维度都与运动后的情感反应有显著性相关；成败结果是影响被试归因和情感反应的重要因素；运动中的效能期望、归因方式和情感反应均存在着显著的性别差异。     

Poverty and the Peril of Particulars

Moral extremists argue for a demanding duty of poverty relief by leveraging powerful intuitions about our duties to rescue those close at hand. I clear the way for a less demanding duty by arguing that this argumentative strategy commits the extremist to a conception of our duty in the face of global poverty that is deeply at odds with our convictions about how we may discharge that duty. These convictions reveal that global poverty and easy rescue cases give rise to duties of different kinds: whereas duties of rescue are ultimately explicable by appeal to moral claims to assistance, duties of poverty relief are not. The extremist’s most compelling argumentative strategy is therefore not viable—he may not straightforwardly appeal to facts about the demandingness of duties of rescue in arguing for demanding duties of poverty relief.     

Risk- and protective factors for memory plasticity in aging

ABSTRACT

Risk and protective factors for cognitive function in aging may affect how much individuals benefit from their environment or life experiences by preserving or improving cognitive abilities. We investigated the relations between such factors and outcome from episodic-memory training in 136 healthy young and older adults. Tested risk factors included carrying the ?4 variant of the apolipoprotein E allele (APOE), age, body mass index, blood pressure, and cholesterol. Protective factors included higher levels of education, intelligence quotient (IQ), physical activity, fatty acids, and vitamin D. Average increases in memory performance were seen after training, with ample variation between individuals. Being young, female, and having higher IQ were positive predictors of memory improvement. No other relationships were observed. Similar benefit was observed across APOE allelic variation. This indicates that beyond IQ, age, and sex, known risk -and protective factors of cognitive function in aging were not significantly related to memory plasticity.     

Towards a synthesis of personality,temperament, motivation,emotion and mental health models within the Circumplex of Personality Metatraits

The paper presents empirical verification of the Circumplex of Personality Metatraits (CPM) that overcomes some problems with the Big Five and enables the integration of various constructs and models developed within many sub-disciplines of psychology. Empirical verification of the model was conducted on a group of 1045 participants in two steps: (1) validation of the model (e.g., the circular arrangement of the metatraits, and relations with the Big Five); (2) verification of the synthesizing potential of this model by testing the predicted locations of temperamental traits, interpersonal traits, values, affects, and mental health constructs within the CPM. It has been found that the CPM can be treated as a matrix accommodating constructs described by circumplex, circular, and noncircular models.
