本研究分别在无时间压力和有时间压力的条件下,通过两个实验探究了图标语义距离?目标数量以及目标类型对雷达界面信息工作记忆的影响?结果发现无时间压力下图标语义距离在工作记忆的编码提取上没有差异,而有时间压力下,强语义图标相较于弱语义图标在工作记忆的提取上具有优势;且无论是在无时间压力下还是有时间压力下,工作记忆容量最佳为3个目标项;对敌机的提取时长于友机长于不明飞行物?结果表明仅在有时间压力下强语义图标在信息提取上具有优势,验证了工作记忆容量的限制,为雷达界面的设计提供了参考意见?     

An inverse Ruddlesden-Popper nitride Ca7(Li1−xFex)Te2N2 grown from Ca flux

Nitridoferrates containing monovalent iron ions are a class of materials of recent interest as potentially novel magnetic materials. Aiming at the exploration of nitridoferrates of calcium, we report the single crystal growth from Ca ?ux and crystal structure of the first member (n?=?2) of a series of inverse Ruddlesden-Popper nitrides with a general formula of A_n?1A'₂B_nX_3n+1, where A?=?Li/Fe, A'?=?Te, B?=?N, and X?=?Ca. Single crystal X-ray diffraction analyses indicate the crystal with a composition of Ca₇(Li_0.32(1)Fe_0.68(1))Te₂N₂ and the tetragonal space group I4/mmm (a?=?4.7884(1) Å, c?=?25.3723(4) Å, Z?=?2). The structure features alternately stacking NaCl-type A'X slabs and the perovskite-type ABX₃ slabs along the c axis. The Li/Fe atoms are located in cuboctahedral cavities surrounded by eight Ca₆N octahedra in the ABX₃ slab. This work demonstrates the viability of the Ca-rich ?ux as a suitable solvent for the exploration of new complex nitrides with interesting crystal structure and properties.     

Modeling the Covariance Structure of Complex Datasets Using Cognitive Models: An Application to Individual Differences and the Heritability of Cognitive Ability

Understanding individual differences in cognitive performance is an important part of understanding how variations in underlying cognitive processes can result in variations in task performance. However, the exploration of individual differences in the components of the decision process—such as cognitive processing speed, response caution, and motor execution speed—in previous research has been limited. Here, we assess the heritability of the components of the decision process, with heritability having been a common aspect of individual differences research within other areas of cognition. Importantly, a limitation of previous work on cognitive heritability is the underlying assumption that variability in response times solely reflects variability in the speed of cognitive processing. This assumption has been problematic in other domains, due to the confounding effects of caution and motor execution speed on observed response times. We extend a cognitive model of decision‐making to account for relatedness structure in a twin study paradigm. This approach can separately quantify different contributions to the heritability of response time. Using data from the Human Connectome Project, we find strong evidence for the heritability of response caution, and more ambiguous evidence for the heritability of cognitive processing speed and motor execution speed. Our study suggests that the assumption made in previous studies—that the heritability of cognitive ability is based on cognitive processing speed—may be incorrect. More generally, our methodology provides a useful avenue for future research in complex data that aims to analyze cognitive traits across different sources of related data, whether the relation is between people, tasks, experimental phases, or methods of measurement.

Examining the dimensional structure and factorial validity of the Bar-On Emotional Quotient Inventory in a sample of male athletes

Objectives

Research examining how emotional intelligence (EI) relates to the performance of athletes has been conducted using various EI measures including the Bar-On Emotional Quotient Inventory (EQ-i; Bar-On, 1997), but no one has investigated the factor structure of the EQ-i in the area of sport psychology. The current study explored the dimensional structure and factorial validity of the EQ-i in a sample of male athletes.

Design

Confirmatory factor analysis was used to examine [Bar-On, 1997] and [Bar-On, 2004] model of emotional-social intelligence and the 1-5-15 dimensional structure which underpins the EQ-i.

Method

A total sample of 706 male athletes from various sports and competing at the national age group level through to the professional level of competition completed the EQ-i.

Results

Confirmatory factor analyses demonstrated that the 1-5-15 dimensional structure was a poor fit for the data. A re-specification of the model representing the best fit for the data was a 1-4-15 dimensional structure. The factorial validity of the individual subscales was also examined at the item level using confirmatory factor analysis. Thirteen of the 15 subscales showed close, reasonably good, or mediocre fit for the data.

Conclusion

Further construct validation of Bar-On’s model and measure is required. Sport psychologists administering the EQ-i in applied practice should consider using the EQ-i subscales rather than referring back to the 1-5-15 dimensional structure.     

Psychoanalysis meeting the challenges of globalisation: Commentary on Cláudio Laks Eizirik's paper

Abstract

Identity and structure as signifiers of the unconscious are in flux as a result of the evaporation of the relations in the modern world. The author develops some hypotheses on the input of the changing identity in respect to the psychoanalytic encounter in therapy and to processes in institutions. He comes to the conclusion that the orientation to the individual dynamics, the therapy room and the therapeutic relationship, which is at present substantial for most analysts, will no longer be relevant. Whether we will be successful or not as psychoanalysts depends on whether we see the world growing together, share the responsibility for it and take up the burning questions of globalisation.     

The role of affect in attitudes toward organ donation and donor-relevant decisions

We argue that affect plays a vital role in attitudes toward organ donation and that reluctance to become an organ donor is likely to be related to the experience of affective ambivalence. Assessing the affect associated with organ donation could help to predict donor-relevant decisions. Results of a confirmatory factor analysis on 464 students showed that affective evaluations can be distinguished both from cognitive evaluations and from overall evaluations. As expected, affective evaluations revealed ambivalence (using the ‘Griffin’ measure of ambivalence) toward organ donation, whereas the two other types of evaluations did not. Results of a follow-up study using logistic regression (n?=?85), showed that affective evaluations predicted donor-relevant decisions six months later. The present findings support the proposal to include separate affective evaluations in measures of attitudes to organ donation. More general implications for the measurement and structure of attitudes in health related domains are discussed.     

Analysis of the relation between structure and the superconducting transition in YBa2 Cu3 O∼7

Abstract

It is shown that in the high-T_c YBa₂ Cu₃ O_～7 superconductor the critical temperature is a function of the orthorhombic distortion (b–a)/a of the unit cell. From the extrapolation of the (b - a)/a ratio against T_c , a maximum critical temperature of 66 K for the tetragonal phase of YBa₂ Cu₃ O_～7 was predicted. From the correlation between the transition width δT_c and the orthorhombic distortion there was deduced an upper limit for T_c , in the orthorhombic phase of YBa₂ Cu₃ O_～7 of 94·5K.
