Smartphone use and daily cognitive failures: A critical examination using a daily diary approach with objective smartphone measures

While smartphones have brought many benefits and conveniences to users, there is continuing debate regarding their potential negative consequences on everyday cognition such as daily cognitive failures. A few cross-sectional studies have found positive associations between smartphone use and cognitive failures. However, several research gaps remain, such as the use of cross-sectional designs, confounds related to stable individual differences, the lack of validity in self-report measures of smartphone use, memory biases in retrospective self-reports, and the lack of differentiation between smartphone checking and smartphone screen time. To simultaneously address the aforementioned shortcomings, the current study examined the within-person associations between various objective indicators of smartphone use and daily cognitive failures using a 7-day daily diary study. Multilevel modelling revealed that smartphone checking, but not total smartphone screen time, predicted a greater occurrence of daily cognitive failures at the within-person level. Surprisingly, we also found negative within-person associations between smartphone screen time for social- and tools-related applications and daily cognitive failures, suggesting that some types of smartphone use may temporarily benefit one's cognitive functioning. This finding demonstrates the importance of studying the specific functions of smartphone use and their differential cognitive consequences, as well as highlights the complex relations between smartphone use and cognition.     

Appearance and reality

There is tension between the appealing idea that visual experience puts us in touch with objective reality and the doctrine of perceptual relativity, the claim that experience varies with such factors as distance, lighting, and angle of view. In this paper I present arguments for relativity, and then go on to propose that in view of relativity, we should believe that the properties presented to us in perception are relational and viewpoint‐dependent. I conclude by sketching a theory of how we nonetheless manage to achieve contact with objective properties. According to the theory, such contact is best explained in terms of perceptual representations acting in concert with cognitive and motoric representations, not in terms of perceptual representations alone.     

基于基尼指数的双目标CD-CAT选题策略

双目标CD-CAT的测验结果既可用于形成性评估也可用于终结性评估。基尼指数可度量随机变量的不确定性程度, 值越小则随机变量的不确定程度越低。本文用基尼指数度量被试知识状态类别以及能力估计置信区间后验概率的变化, 提出基于基尼指数的选题策略。Monte Carlo实验表明与已有的选题策略相比, 新策略的知识状态分类精度和能力估计精度都较高, 同时能有效兼顾题库利用均匀性, 并能快速实时响应, 且受认知诊断模型和被试知识状态分布的影响较小, 可用于实际测验中含多种认知诊断模型的混合题库。     

Embracing the other: Revisiting the epistemological foundations of family systems therapy

Family systems therapy originated in the 1960s, 1970s, and 1980s through the work of innovative thinkers and clinicians. However, despite the creative contributions of the mentioned colleagues and of later innovations in family therapy theory and practice, it seems as though the dominant culture of establishment psychiatry in the United States (and in most Western countries) to this day has not seriously incorporated relationships, social context, or community connectedness into the treatment of individuals with psychiatric diagnoses. For the “psychiatric” patients diagnosed according to the DSM-5, the dominant underlying epistemological perspective is the medical “scientific” paradigm. Within this approach there is a dearth of reflections about the truthfulness of so-called “empirical facts” and a lack of skepticism about the techniques of “measurement” of the psychiatric illness. The alternative, relationship-oriented, context-sensitive, and community-connected thinking paradigm is highlighted here in contrast to the “psychiatric” foundation. This paradigm consists of (a) the awareness that all human Subjects (including “psychiatric” clients) are constituted as such by their relational connection to others; (b) the awareness of our sensitivity to and embeddedness in a socio-economic, cultural, and racial context; and (c) the awareness of our involvement in and connectedness with many kinds of communities.     

阈下知觉研究中觉知状态测量方法的发展与启示

该文对近百年来围绕阈下知觉研究一直争论不休的觉知状态的测量方法进行了全面回顾,通过比较和分析在主观阈限和客观阈限以及不断改进后的其它觉知阈限测量方法条件下所获得的实验结果,并结合有关意识和无意识之间关系的理论假设,认为这种状况本身就否定了有关意识与无意识关系的排它观点。今后的研究应该跳出这一陷阱,并从无意识知觉如何影响有意识的行为以及阈下知觉的神经活动指标等方面开辟研究的新途径。     

心理学研究中社会阶层的操作化界定及其衍生问题

个体的社会阶层反映了其所掌控的客观社会资源(即客观社会阶层)和其主观上所感知到的自身社会地位(即主观社会阶层)的水平。收入(或财产)、职业、受教育程度是研究中常用来反映客观社会阶层的操作化指标。而主观社会阶层的操作化界定既包括对主观阶层进行问卷测量,也包括对其加以实验操纵。心理学研究要基于研究目的以及要考察的具体效应与机制对不同的操作化界定加以取舍,有时也要综合兼顾多种操作化方式。通过选取典型群体来代表不同阶层,这种做法宜慎重采用。同时研究的信效度问题有必要更多加以重视。未来研究应加强关注阶层认同偏差与阶层纵向流动等基础问题,以及因取样偏差而带来的阶层效应被简化的现象,并结合跨文化视角分析不同文化下社会阶层的内涵差异。     

Reflections on the Jungian nature of psychology as the discipline of interiority: a response to Saban's ‘Misunderstandings’

Psychology as the discipline of interiority is the name of the psychology that has developed from Wolfgang Giegerich's work in the field of analytical psychology. This article offers a counterview to that of Mark Saban's claim that Giegerich's psychology is ‘irrelevant’ to Jungians today and is based on a fundamental misunderstanding of the nature of Jungian psychology. It will be shown that, in fact, it is a fundamental misunderstanding of Giegerich's work that has led Saban to form erroneous conclusions. Links between Jung's and Giegerich's conceptions of the ‘objective psyche’ will be highlighted, along with other examples of how, contrary to Saban's conclusions, psychology as the discipline of interiority has obvious connections to, and grounding in, Jungian psychology.     

Margolis as Columbia Naturalist

Is Joseph Margolis a member of the often neglected school of “Columbia naturalism”? Columbia naturalism promoted a distinctive non-reductive nationalism in mid-twentieth-century America. Inspired by pragmatism, and Dewey in particular, its members included Ernest Nagel, John Herman Randall, Joseph Blau, Herbert Schneider, and Justus Buchler. Margolis received his degree from Columbia in 1953. Neither his early work in aesthetics nor his mature attempt to justify pragmatic themes in an uncompromising dialogue with analytic and continental philosophy seems particularly “Columbian.” Neither does his radical endorsement of a kind of relativism. However, Margolis is after all some kind of naturalist. Furthermore, the Columbians shared a forgotten doctrine, called “objective relativism.” If the combination of naturalism and relativism is a Columbian fruit, Margolis may have has fallen closer to the tree than first appears.     

The positive eating scale: relationship with objective health parameters and validity in Germany,the USA and India

Objective: The prevailing focus regarding eating behaviour is on restriction, concern, worry and pathology. In contrast, the purpose of the present studies was to focus on a positive relationship with eating in non-clinical samples from Germany, the USA and India.

Design: In Study 1, the Positive Eating Scale (PES) was tested and validated in a large longitudinal sample (T1: N = 772; T2: N = 510). In Study 2, the PES was tested in online samples from the USA, India and Germany (total N = 749).

Main Outcome Measures: Health risk status was measured in Study 1 with objective health parameters (fasting serum glucose, triglycerides, high-density lipoprotein cholesterol, blood pressure, waist circumference, BMI).

Results: Study 1 revealed acceptable psychometric properties of the PES, internal consistency (α = .87), as well as test–retest reliability after six months (r = .67). Importantly, a positive relationship with eating was associated with decreased health risk factors six months later. In Study 2, the structure of the PES was confirmed for German, Indian and US-American adults, suggesting validity across remarkably different eating environments.

Conclusion: A positive relationship with eating might be a fruitful starting point for prevention and intervention programmes promoting physical and psychological health.     

A Multicriteria Decision‐Making Application to the Conceptual Design of Mechanical Components

Early design is crucial for the success of the final product. In the conceptual design phase, several constraints, criteria, objectives and disciplines have to be considered. To this aim, multidisciplinary optimization has proven effective for the solution of engineering design problems, even in the industrial every‐day practice, to improve and simplify the work of designers in a successful quest of the best compromise solution. In this paper, a multicriteria decision‐making (MCDM)‐based design platform for early optimal design of industrial components is proposed. In a group decision‐making context, the selection of the most suitable component among several possible layouts is performed by means of a group Fuzzy Technique for Order of Preference by Similarity to Ideal Solution approach. Hence, a multi‐objective optimization is performed on the selected component by applying a multi‐objective particle swarm optimization for finding optimal component dimensions. An industrial case study is presented for showing the efficiency of the multicriteria decision‐making‐based design platform, regarding an innovative and low‐cost solution to increase the duration of heel tips in women's shoes.
