An exploratory investigation of the reliability and validity of the Independent-Interdependent Problem-Solving Style Scale

The Independent-Interdependent Problem-Solving Scale is based on Cross et al.'s conceptualisation of relational-interdependent self-construal. The IIPSS provides a relatively context-free measure of people's tendencies to solve problems independently or with the help of others. Because previous investigations have not provided extensive evidence for the reliability and validity of the IIPSS, the current research aimed to test the psychometric properties of this novel measure. Investigations of four student samples (combined N = 1157) and one sample comprised of academic researchers (N = 198) generally supported the reliability and validity of the IIPSS. Exploratory factor analysis of IIPSS items yielded a single factor structure. However, confirmatory factor analyses did not demonstrate good model fit for the one factor solution and instead yielded good model fit for two underlying factors. The IIPSS showed adequate test–retest reliability and predicted positive associations with social personality traits. It also showed no significant associations with measures of demand characteristics and social desirability. Future research needs to be undertaken to further assess the factor structure and address shortcomings of the present research such as utilising objective data in addition to self-reports to assess the scale's validity.     

Stepwise variable selection in factor analysis

It is very important to choose appropriate variables to be analyzed in multivariate analysis when there are many observed variables such as those in a questionnaire. What is actually done in scale construction with factor analysis is nothing but variable selection.In this paper, we take several goodness-of-fit statistics as measures of variable selection and develop backward elimination and forward selection procedures in exploratory factor analysis. Once factor analysis is done for a certain numberp of observed variables (thep-variable model is labeled the current model), simple formulas for predicted fit measures such as chi-square, GFI, CFI, IFI and RMSEA, developed in the field of the structural equation modeling, are provided for all models obtained by adding an external variable (so that the number of variables isp + 1) and for those by deleting an internal variable (so that the number isp – 1), provided that the number of factors is held constant.A programSEFA (Stepwise variable selection in Exploratory Factor Analysis) is developed to actually obtain a list of the fit measures for all such models. The list is very useful in determining which variable should be dropped from the current model to improve the fit of the current model. It is also useful in finding a suitable variable that may be added to the current model. A model with more appropriate variables makes more stable inference in general.The criteria traditionally often used for variable selection is magnitude of communalities. This criteria gives a different choice of variables and does not improve fit of the model in most cases.The URL of the programSEFA is http://koko15.hus.osaka-u.ac.jp/~harada/factor/stepwise/.

All Behavior is choice: Revisiting an evolutionary theory's account of behavior on single schedules

The axiomatic principle that all behavior is choice was incorporated into a revised implementation of an evolutionary theory's account of behavior on single schedules. According to this implementation, target responding occurs in the context of background responding and reinforcement. In Phase 1 of the research, the target responding of artificial organisms (AOs) animated by the revised theory was found to be well described by an exponentiated hyperbola, the parameters of which varied as a function of the background reinforcement rate. In Phase 2, the effect of reinforcer magnitude on the target behavior of the AOs was studied. As in Phase 1, the AOs' behavior was well described by an exponentiated hyperbola, the parameters of which varied with both the target reinforcer magnitude and the background reinforcement rate. Evidence from experiments with live organisms was found to be consistent with the Phase-1 predictions of the revised theory. The Phase-2 predictions have not been tested. The revised implementation of the theory can be used to study the effects of superimposing punishment on single-schedule responding, and it may lead to the discovery of a function that relates response rate to both the rate and magnitude of reinforcement on single schedules.     

A Review of Articles Using Observation Methods to Study Creativity in Education (1980–2018)

This paper reports on an integrative literature review of published articles that used either quantitative or qualitative observation methods to research creativity in learning contexts. Observation is an empirical research method used in quantitative and qualitative naturalistic studies focused on understanding behavior and interactions as they unfold in real-time, which makes it particularly salient for examining the processes associated with the generation and adoption of creative ideas. However, observation remains underutilized in the field of creativity studies, partly because data collection can be time and resource intensive, but also because there are a lack of protocols and recommended research practices for observing creative thinking and problem solving in an educational environment that covers all phases of design, collection, analysis, and reporting. Thirty-seven articles from 1980–2018 were reviewed along seven dimensions: definition of creativity, unit of observation, observer role, observation sampling method, research design, data collection, and data analysis. The paper concludes with five recommendations for using observation to advance the state of research on creativity and education.     

Concealability beliefs facilitate navigating intergroup contexts

Living in a diverse world requires the ability to navigate intergroup contexts. However, interacting with outgroup members can cause anxiety that leads to lower-quality interactions and avoidance of future contact. One reason people experience this anxiety is the concern that others will judge them on the basis of an identity. These concerns may be reduced among people who believe the identity is unperceivable by others. The belief that one's identity is concealable may therefore reduce intergroup anxiety and ease people's experiences in intergroup contexts. The present work tests this proposition in two studies and finds that individual differences in concealability beliefs are negatively associated with intergroup anxiety and positively associated with the propensity to initiate intergroup contact and with the quantity and quality of people's cross-group friendships. Materials, data, and code for both studies and a pre-registration for Study 2 are available online ( https://osf.io/4cjhg/ ).     

Distancing from a stigmatized social identity: State of the art and future research agenda on self-group distancing

Despite equal rights, minority groups such as ethnic minorities, LGBTQ + people, and people with mental or physical disabilities face discrimination on a day-to-day basis in subtle and hard-to-recognize forms. As discrimination slips beneath the surface, it becomes difficult to fight the stigma using collective social identity coping mechanisms. Instead, individual mobility responses such as distancing the self from the stigmatized identity (“self-group distancing”) become more viable as a way to improve one's individual standing. In this overview of the state of the art, we take a social identity lens to reflect on the current empirical knowledge base on self-group distancing as a coping mechanism and provide a framework on what self-group distancing is; when, where and why self-group distancing likely occurs; and what its consequences are at the individual and the collective level. The contributions in this special issue provide novel insights into how these processes unfold, and serve as a basis to set a future research agenda, for example on what can be done to prevent self-group distancing (i.e., interventions). Together, the insights highlight that while self-group distancing may seem effective to (strategically and temporarily) alleviate discomfort or to improve one's own position, on a broader collective level and over time self-group distancing tends to keep the current unequal social hierarchy in place.     

Should we pass on minimum passing distance laws for cyclists? Comparing a tactical enforcement option and minimum passing distance laws using signal detection theory

Legislation mandating minimum distances for motorists passing cyclists is seen by advocates as a straightforward way to increase the perceived safety of cycling and thus remove a prominent barrier to the uptake of cycling. The evidence, however, is not as clear. The alternative to compliance-based enforcement via Minimum Passing Distance Laws (MPDLs) is performance-based enforcement as recently highlighted by UK Police forces under the name ‘Operation Close Pass’. This existing legislation and enforcement method relies on police officer judgement and discretion. For a MPDL to be introduced it has to show an improvement by identifying more manoeuvres that make cyclists feel unsafe, whilst at the same time not penalising drivers for manoeuvres that are benign. This study uses Signal Detection Theory to show that on almost every measure the current performance-based enforcement is preferable. Officer discretion is aligned more closely to cyclists’ real-world perceptions of risk than an objective, compliance-based MPDL. Any level of enforcement harshness can be achieved equally well, if not better, through officer discretion than through a fixed passing distance law, with the former being significantly easier to adjust if needed. Further discussion about the unintended effects of passing distance laws is discussed, such as the risk of a net loss to the effectiveness of cyclist safety because it is more difficult to prosecute and enforce manoeuvres which make cyclists feel unsafe than the performance-based alternative.     

污名化对被污名个体人际互动的影响

污名是指个体所具有不受欢迎的特征, 这种特征会导致个体在一定社会背景下被主流文化群体贴负性标签、贬低、侮辱而遭受到污名化。污名化对个体或群体本身会有消极影响, 不仅会使个体遭受到来自他人的歧视、排斥或拒绝等这些直接作用于自身的外部影响, 还会进一步消极影响被污名个体在人际互动中的表现和行为反应。被污名个体与主流文化群体之间的消极互动又会进一步加剧主流文化对被污名个体或群体的排斥, 形成恶性循环。从被污名个体的角度出发, 有助于更加深入地探讨污名化对被污名个体人际互动方面的影响以及被污名个体采取的应对方式。     

心理学研究方法中“质”与“量”的整合

心理学研究方法中“质”与“量”的分歧由来已久。虽然“质”与“量”的研究方法各有其优势,但是也不可避免地存在一些弱点。如果将质与量的方法进行整合,使之进行优势互补,从而更大可能地揭示心理现象发生和发展的规律是我们所面临的课题。要对质的研究方法与量的研究方法进行整合,首先必须“去范式”,将研究的重点聚焦于研究问题,而非范式;其次必须将质性的资料与定量的资料放在同一个层面上进行比较。该文通过一个案例,向读者介绍如何进行“质”与“量”的研究方法的整合
