Development and validation of the Eyewitness Metamemory Scale

Metamemory can be defined as the knowledge about one's memory capabilities and about strategies that can aid memory. In this paper, we describe the development and validation of the Eyewitness Metamemory Scale (EMS), tailored specifically for use in face memory and eyewitness identification settings. Participants (N = 800) completed the EMS and other measures on general metamemory. Results from exploratory and confirmatory factor analysis revealed good factorial validity, internal consistency, and content validity. The EMS items emerged into three distinct factors: memory contentment, memory discontentment, and memory strategies. The EMS is a brief and easily administrable questionnaire that might be used to assess self‐ratings of face recognition capacity and use of strategies to encode faces.     

Group structure and entitativity in group fitness: considering groupness at within- and between-group levels

Objective: How can we distinguish between a collection of individuals exercising alongside one another from group that is exercising ‘together’? This question is central to research on the extent that individuals perceive their fitness settings to entail core features of groups. To advance understanding of the nature of groupness and its implications in exercise, the current study (a) evaluated a brief measure of groupness and (b) examined the extent that groupness predicted perceptions of exertion and affect.

Design: Participants included 633 exercisers (M_age?=?33.92, SD?=?11.05, 74% female) who completed surveys after group fitness classes (k?=?34).

Main outcome measures: Groupness, affect, exertion, and group cohesion.

Results: Exploratory structural equation modelling provided support for a two-factor solution reflecting entitativity and group structure as subdimensions of groupness. The groupness factors were differentially associated with theoretically relevant aspects of classes (e.g. synchronised movement), the individual (e.g. number of members interacted with), as well as group cohesion. Groupness also predicted perceived exertion and affect.

Conclusion: Our research provides support for a brief measure of groupness, advances theory related to how individuals perceive exercise groups, and provides evidence regarding how broader experiences during exercise may relate to exercisers’ perceptions of groupness.     

自闭症诊断与治疗研究动向综述

自1943年LeoKanner教授发表第一篇关于自闭症的研究论文以来,经过半个多世纪的不断深入研究,儿童自闭症这一广泛性发展障碍领域的理沦与技术已越显成熟．不仅继承了Kanner教授的一些经典的东西,而且也修正了他关于自闭症的一些错误看法,并扩充了由于Kanner所处时代的科技水平的局限性而不可能得出的一些最新研究成果。本文试图就国内外在自闭症的诊断与治疗方面的一些研究成果和研究动向作一个全面的综述。     

我国城市居民消费心理预期的结构及其影响因素研究

本研究采用自编《消费心理预期结构问卷》对1097名城市居民进行了研究,结果表明：1《消费心理预期结构问卷》具有较高的信度和效度;2．消费心理预期由预测经历、信息量、价格知觉水平、信息来源与渠道,以及预测依据等5个因素构成;3．现阶段,我国城市居民消费心理预期的一般特点是预期的准确性不高预期的理性化程度尚有待提高;影响消费心理预期结构的主要因素是消费者的性另、年龄、学历、职业和所在城市等变量。     

中国人获得感的结构研究

获得感是一个具有心理内涵与时代特色的新生概念。为了探究获得感的结构内涵,通过自由联想法形成量表的初始项目,先后进行两次预测并根据结果修订量表。然后对量表进行正式施测并检验其信效度,同时采用中文版生活满意度量表和幸福倾向量表进行效标效度检验。结果显示,中国人的获得感是个体对获取自身需求满足的内容、实现途径与所需条件的认知评价以及在此过程中的心理体验,包括获得体验、获得环境、获得内容、获得途径和获得分享五个维度。信效度分析表明,编制的中国人获得感量表符合心理测量学的标准,可用于相关的社会心理研究与应用。     

心理贫穷感对决策的影响

“贫穷感”是个体与金钱相关的、相对稳定的内心感受,包含不安全感、焦虑感、厌恶感、不满足感和金钱关注五个维度,用以描述个体与金钱相关的认知和情绪上的差异。其概念内涵由28位心理学专家和社会学专家共同界定。贫穷感自评量表是一个15题5点Likert量表。通过问卷法对420位社会人员测量发现,贫穷感与生命史Mini-K测量结果显著负相关。贫穷感越高的个体越倾向于生命史快策略。     

Children's scale errors: A by‐product of lexical development?

Scale errors occur when young children seriously attempt to perform an action on an object which is impossible due to its size. Children vary substantially in the incidence of scale errors with many factors potentially contributing to these differences, such as age and the type of scale errors. In particular, the evidence for an inverted U‐shaped curve of scale errors involving the child's body (i.e., body scale errors), which would point to a developmental stage, is mixed. Here we re‐examine how body scale errors vary with age and explore the possibility that these errors would be related to the size and properties of children's lexicon. A large sample of children aged 18–30 months (N = 125) was tested in a scale error elicitation situation. Additionally, parental questionnaires were collected to assess children's receptive and expressive lexicon. Our key findings are that scale errors linearly decrease with age in childhood, and are more likely to be found in early talkers rather than in less advanced ones. This suggests that scale errors do not correspond to a developmental stage, and that one determinant of these errors is the speed of development of the linguistic and conceptual system, as a potential explanation for the individual variability in prevalence.     

Rainbows in the society: A measure of hope for society

The aim of this study was to develop and validate a measure of social hope. Previous studies have extensively reported on personal hope and its outcomes. Although a few studies have suggested the concept of collective or social hope, there is no instrument to assess the construct. In this study, we created a 5‐item scale, drawing on Snyder's hope theory, and collected two sets of survey data online. Analysis of these data sets revealed that the new scale was structurally unidimensional and internally consistent. In association with Snyder's State Hope Scale, the Social Hope Scale showed convergent and discriminant validity. The social hope construct also exhibited theoretically meaningful relationships with political efficacy and self‐construal (concurrent validity). Finally, social hope was higher for those who had participated in certain types of social activism than it was for those who had not (predictive validity). These results suggest that the Social Hope Scale is a reliable and valid self‐report measure of hopeful thinking for society.     

Development and validation of the Indonesian Well‐being Scale

The present study describes the development and validation of a new instrument to measure the well‐being of Indonesian people. Items were generated by taking into account the recent cross‐cultural developments in the literature. Participants (N = 1,028) from a number of provinces in Indonesia completed an online or a paper questionnaire containing a battery of measures, including the new well‐being instrument. The total sample was randomly split into two equal groups. An exploratory factor analysis (n = 516) was conducted on one half to explore the factor structure of the new scale, which resulted in a 24‐item scale with a four‐factor solution. The four factors were (a) Basic Needs, (b) Social Relation, (c) Acceptance, and (d) Spirituality. A confirmatory factor analysis was conducted on the second half (n = 516), which confirmed the four‐factor structure with 20 items emerging as the best and most parsimonious fit of the data. The psychometric properties of the final scale were tested on the whole sample. The new scale displayed sound internal consistency, test‐retest reliability, and divergent, convergent, and discriminant validity. The scale has the potential to be used in future research which examines well‐being in the Indonesia context. Future directions and limitations of the study are discussed.     

Different practice effects for males and females by psychometric and chronometric mental-rotation tests

Gender differences in the psychometric mental-rotation test are usually larger than in the chronometric version. In both tests, practice effects appear for males and females. In this study, 104 participants (54 females, 50 males, age: 21.72 years) completed both tests in counterbalanced order. In the chronometric test, only males reacted and rotated significantly faster after the practice with the psychometric test. A strong practice effect independently of gender was found in the psychometric test and a gender difference in accuracy in favour of males. Males reported more confidence and females rated the perceived pressure of the time limit of the psychometric test higher than males. Consequently, differences in confidence after the practice could partly explain the gender differences in the improvements of reaction time and rotational speed. Practice from one mental-rotation test on the performance in another seems to be dependent of participants’ gender and the type of the test.
