Future work selves: how salient hoped-for identities motivate proactive career behaviors

The term future work self refers to an individual's representation of himself or herself in the future that reflects his or her hopes and aspirations in relation to work. The clearer and more accessible this representation, the more salient the future work self. An initial study with 2 samples (N = 397; N = 103) showed that future work self salience was distinct from established career concepts and positively related to individuals' proactive career behavior. A follow-up longitudinal analysis, Study 2 (N = 53), demonstrated that future work self salience had a lagged effect on proactive career behavior. In Study 3 (N = 233), we considered the role of elaboration, a further attribute of a future work self, and showed that elaboration motivated proactive career behavior only when future work self salience was also high. Together the studies suggest the power of future work selves as a motivational resource for proactive career behavior.     

意象思维与躯体化症状：疾病表达的文化心理学途径

意象思维是中国人的传统思维模式, 它通过观物取象和取象比类的方式认知世界、推演联系。这种思维模式塑造了中国人特有的身心不分而非两分的身体观、疾病观和治疗观。在中国人的观念中, 身体不仅仅是一具生理躯体, 还具有气、阴阳、五行等本土概念所体现的弥合物质与精神、联结生理与心理的模糊性与开放性。人们在表达疾病感觉时通常不分生理与心理, 任何一方面出现不适感觉即可认为自己生病, 在面对心理医生时也倾向于同时报告躯体状况与心理感觉, 从而使得临床报告出现较高的躯体化报告率。这正是文化心理影响疾病表达的体现。这也使得疾病不仅是一种医学现象, 也是一种文化现象; 医学不仅需要生理知识, 也需要人文知识。

Reaction Time Inconsistency in a Spatial Stroop Task: Age-Related Differences Through Childhood and Adulthood

ABSTRACT

Age-related differences in inconsistency of reaction time (RT) across the life span were examined on a task with differing levels of demand on executive control. A total of 546 participants, aged 5 to 76 years, completed a spatial Stroop task that permitted observations under three conditions (congruent, incongruent, and neutral) according to the correspondence between the required response (based on stimulus direction) and stimulus location. An interference effect was observed across all ages. Analyses of neutral condition data replicated previous research demonstrating RT inconsistency follows a U-shaped developmental curve across the life span. The relationship between age and inconsistency, however, depended on condition: inconsistency in the congruent condition was higher than inconsistency in both the neutral and incongruent conditions across middle-aged groups. Reaction time inconsistency may reflect processing efficiency that is maximal in young adulthood and may also be sensitive to fluctuations in performance that reflect momentarily highly efficient responding.     

The Relationship between Everyday Problem Solving and Inconsistency in Reaction Time in Older Adults

ABSTRACT

The purpose of the present study was to investigate whether inconsistency in reaction time (RT) is predictive of older adults' ability to solve everyday problems. A sample of 304 community dwelling non-demented older adults, ranging in age from 62 to 92, completed a measure of everyday problem solving, the Everyday Problems Test (EPT). Inconsistency in latencies across trials was assessed on four RT tasks. Performance on the EPT was found to vary according to age and cognitive status. Both mean latencies and inconsistency were significantly associated with EPT performance, such that slower and more inconsistent RTs were associated with poorer everyday problem solving abilities. Even after accounting for age, education, and mean level of performance, inconsistency in reaction time continued to account for a significant proportion of the variance in EPT scores. These findings suggest that indicators of inconsistency in RT may be of functional relevance.     

毕生控制理论的新发展:调节模型及控制策略

毕生控制理论能较好地解释毕生发展,认为适应能力的中心特质是动机调节,可促进个体发展并使其达到最优化.生命历程被视为由一列有序的目标定向行动周期组织而成,该周期包括目标选择、目标结合及目标解除.基于该角度,在回顾控制理论的基本概念、初级控制的首要性和毕生发展轨迹基础上,对毕生发展的调节模型和控制策略的适应功能进行了综合阐述.未来研究应从跨文化情境下的适用性、满足适应目标选择三个因素的进一步验证和成功老龄化相关研究等方面开展更深入的探讨.     

What is a Line?

Since the discovery of incommensurability in ancient Greece, arithmeticism and geometricism constantly switched roles. After ninetieth century arithmeticism Frege eventually returned to the view that mathematics is really entirely geometry. Yet Poincaré, Brouwer, Weyl and Bernays are mathematicians opposed to the explication of the continuum purely in terms of the discrete. At the beginning of the twenty-first century ‘continuum theorists’ in France (Longo, Thom and others) believe that the continuum precedes the discrete. In addition the last 50 years witnessed the revival of infinitesimals (Laugwitz and Robinson—non-standard analysis) and—based upon category theory—the rise of smooth infinitesimal analysis and differential geometry. The spatial whole-parts relation is irreducible (Russell) and correlated with the spatial order of simultaneity. The human imaginative capacities are connected to the characterization of points and lines (Euclid) and to the views of Aristotle (the irreducibility of the continuity of a line to its points), which remained in force until the ninetieth century. Although Bolzano once more launched an attempt to arithmetize continuity, it appears as if Weierstrass, Cantor and Dedekind finally succeeded in bringing this ideal to its completion. Their views are assessed by analyzing the contradiction present in Grünbaum’s attempt to explain the continuum as an aggregate of unextended elements (degenerate intervals). Alternatively a line-stretch is characterized as a one-dimensional spatial subject, given at once in its totality (as a whole) and delimited by two points—but it is neither a breadthless length nor the (shortest) distance between two points. The overall aim of this analysis is to account for the uniqueness of discreteness and continuity by highlighting their mutual interconnections exemplified in the nature of a line as a one-dimensional spatial subject, while acknowledging that points are merely spatial objects which are always dependent upon an extended spatial subject. Instead of attempting to reduce continuity to discreteness or discreteness to continuity, a third alternative is explored: accept the irreducibility of number and space and then proceed by analyzing their unbreakable coherence. The argument may be seen as exploring some implications of the view of John Bell, namely that the “continuous is an autonomous notion, not explicable in terms of the discrete.” Bell points out that initially Brouwer, in his dissertation of 1907, “regards continuity and discreteness as complementary notions, neither of which is reducible to each other.”

动作自主性与结果性质对不同预测性条件下施动感的影响

采用时间估计法考察动作自主性水平、动作结果性质(利己、利他、中性)以及结果是否可预测对施动感的影响。结果发现, 高自主性的自由选择条件比低自主性的服从条件增强了个体的施动感, 且不受动作结果性质与结果是否可预测的影响; 在低自主性的服从条件下, 当结果可预测时利己结果比利他结果的施动感更强, 而在结果不可预测时利己和利他结果的施动感没有区别, 但均弱于中性结果。这揭示出动作的主观意愿在施动感产生过程中的重要作用, 同时在自主性较低的服从条件下, 对利己或利他道德属性的动作结果能否被预测, 对个体的施动感产生了不同的影响。研究结果说明具有利己或利他道德属性的动作对施动感会产生自上而下的调节作用, 且这种调节作用在低自主条件下较为突显。
