An experimental test to reveal negative side-effects of high treatability information on preventative health behaviour

Objectives: When the course of a disease can be positively changed by health professionals the disease can be indicated as ‘highly treatable’. This ‘high treatability information’ (HTI) may have negative side-effects on people’s preventative motivation. This study examined the effects of HTI regarding skin cancer on preventative motivation.

Design: This study employed a 2 (high treatability (HTI) versus low treatability (LTI)) × 2 (high versus low susceptibility)?experiment with a hanging control group. (family) History and self-efficacy were assessed as moderators. Participants (N = 309) were randomly assigned to one of the five conditions.

Main outcome measures: The main outcome was intention to engage in preventative actions regarding skin cancer.

Results: HTI significantly lowered the intention compared to LTI, under the condition of high susceptibility in people with low self-efficacy. In addition, in people with a (family) history of skin cancer, HTI significantly lowered the intention compared to the no-information group.

Conclusion: HTI regarding skin cancer can cause a drop in the preventative motivation. The effects can be conceptualised as negative side-effects of HTI. As substantial proportions of the general population have a (family) history of skin cancer or low self-efficacy, the side-effects may be widespread, possibly increasing the incidence of skin cancer.     

An empirical investigation of a theoretical model for mathematical creativity

In this exploratory study, a theoretical model proposed by Sriraman (2005) consisting of five theoretical principles for optimizing creativity in a K–12 setting was investigated empirically. This was accomplished in two steps. In the first study, the five principles were operationalized by generating a questionnaire consisting of 45 items intended to capture the dimension of each principle. An exploratory maximum‐likelihood factor analysis indicated a relatively robust five factor structure that corresponded with the theoretical model. In the second study, the five factor model was validated using a confirmatory factor analysis. The model was then investigated using a two‐level linear mixed model with a random intercept. The results revealed that motivation and mathematical achievement were significant predictors of mathematical creativity.     

Motor imagery ability and internal representation of movement in children with probable developmental coordination disorder

It has been hypothesised that deficits in the functioning of the mirror neuron system (MNS) and internal modelling may contribute to the motor impairments associated with DCD. These processes can be explored behaviourally through motor imagery paradigms. Motor imagery proficiency of children with and without probable DCD (pDCD) was examined using a complex hand rotation task to explore whether motor imagery strategies could be used during more complex tasks. Forty-four boys aged 7–13 years participated, 22 with pDCD (mean = 9.90 years ± 1.57) and 22 controls (mean = 9.68 years ± 1.53). Participants completed the task twice: with and without motor imagery instructions. Stimuli were presented in two rotational axes – palm/back, and eight 45° rotational steps. Both groups showed evidence of following the biomechanical and postural constraints of actual movements. Responses of children with pDCD were slower and less accurate than controls, with group differences increasing alongside task complexity. A greater impact of biomechanical constraints for accuracy was observed in the DCD group. The response characteristics of children with pDCD likely reflects a reduced capacity to mentally manipulate a body schema and reduced visuo-motor processing capabilities. Behaviourally, these processes are linked to MNS and internal modelling function, suggesting deficits in these systems may contribute to the movement difficulties characteristic of DCD.     

Kindergarten self-control mediates the gender reading achievement gap: A population-based cohort study

Could superior self-control explain the gender difference in reading achievement favoring girls? To test this idea, we drew on a unique population-based sample (N = 11,336) where self-control was measured in kindergarten using a multimethod battery of assessments. Girls showed substantially higher levels of self-control in kindergarten (β = 0.47) and outperformed boys on standardized tests of reading achievement in third/fourth grade (β = 0.20). Further, kindergarten self-control prospectively predicted reading achievement throughout elementary school (β = 0.37). Connecting these findings, our mediation analyses revealed that the female self-control advantage in kindergarten could account for subsequent gender differences in reading achievement. Our results suggest that early gender differences in self-control may represent a key pathway through which gender disparities in reading skills, vocabulary knowledge, and reading comprehension occur.     

Floorgasm: Queer(s), solidarity and resilience in punk

This article explores queer(ed) punk scenes, primarily in Australia. Queer ciswomen, transwomen and non-binary people aged 20–30 years are the informants here in a feminist-informed ethnographic study. They were found to engage strategies of resistance against cismale dominance at punk gigs and events in order to claim queer(ed) territory. In brief, they worked collectively to subvert the dominant patriarchal norms in punk spaces. They mobilised community-building through the politics of Do-It-Together (DIT) as a radical reshaping of the traditional punk ethos of DIY (Do-It-Yourself). They also worked to make gigs more queer-affirmative through mobilising the initiative of safe(r) spaces. We map some queer collective resilience in punk to authorise the expression of counter-hegemonic gender identities. The gig outcome was pleasurable queer solidarity enmeshed with music, a kind of metaphysical ‘floorgasm’.     

不同铆测验设计下多维IRT等值方法的比较

实际应用中测验往往具有多维结构, 如果仍采用单维IRT方法进行等值, 会得到不准确的结果。因此对于多维结构的测验, 需要使用多维IRT等值方法来实现参数的转换。基于共同题设计, 文章通过模拟研究的方法, 考察了不同铆测验设计下几种多维IRT等值方法的表现, 同时考虑了测验长度、两个维度题目数量的比例、铆测验长度、铆测验的选择策略、两个维度之间的相关和等值群体的能力水平差异六个因素的影响。所比较的多维IRT等值方法有：均值/均值(MM)方法, 均值/标准差(MS)方法, Stoking-Lord (SL)方法, Haebara (HB)方法, 最小平方(LS)方法。结果显示：(1) SL, HB和LS方法得到的等值误差均方根最小, 且在各条件下表现较为稳定。(2) MM和MS方法在非等组条件下呈现出很大的误差均方根。(3)铆测验设计对SL, HB和LS方法的等值结果没有显著影响。(4)在两个维度之间的相关较高, 测验长度和铆测验长度较长, 等值群体的能力水平没有差异的条件下, SL, HB和LS方法得到的等值误差均方根最小。     

情绪语音调节面孔表情的识别：ERP证据

采用事件相关电位（ERP）技术考察了情绪语音影响面孔表情识别的时间进程。通过设置效价一致或不一致的“语音-面孔”对,要求被试判断情绪语音和面孔表情的效价是否一致。行为结果显示,被试对效价一致的“语音-面孔”对的反应更快。ERP结果显示,在70-130ms和220-450ms,不一致条件下的面孔表情比一致条件诱发了更负的波形;在450-750ms,不一致条件下的面孔表情比一致条件诱发更正的后正成分。说明情绪语音对面孔表情识别的多个阶段产生了跨通道影响。     

基于fNIRS的运动执行与运动想象脑激活模式比较

使用《运动想象问卷−修订版》筛选出的30名被试(男女各半), 采用功能性近红外光谱成像技术(fNIRS)监测被试在执行实际举哑铃(男生, 4磅和8磅; 女生, 2磅和4磅)任务和想象举同等重量哑铃任务时, 其大脑皮层氧合血红蛋白浓度的变化。结果发现：男女被试在运动执行与运动想象任务下都激活了主运动皮层; 且运动执行的大脑激活水平高于运动想象。在执行实际运动任务时, 运动强度显著影响大脑皮层血氧浓度的变化, 表现出左半球偏侧化优势; 在执行想象运动任务时, 运动强度没有影响大脑皮层血氧浓度的变化, 且无偏侧化现象。     

康德实践理性的事实概念及其对自由的证明

康德实践理性的事实概念指的是道德律或道德律的意识,而道德律本身实际上是道德律的意识。道德律是某种自身肯定的东西,它作为事实肯定了纯粹实践理性的客观实在性,并通过理性的这一积极的概念,证明了它自身在实践上的客观实在性。正是通过道德律这一事实,在思辨哲学那里只具有消极性的自由的原因性的概念,在实践哲学中获得了积极的规定,也成为了一个“事实”。     

The Tromsø Social Intelligence Scale, a self-report measure of social intelligence

Social intelligence is a construct that not only appeals to laymen as a relevant individual difference but also has shown promising practical applications. Nevertheless, the use of social intelligence in research and applied settings has been limited by definitional problems, difficulties in empirically differentiating social intelligence from related constructs, and the complexity of most existing measures of social intelligence. The goal of the present research was to address some of these obstacles by designing a multi‐faceted social intelligence measure that is short and easy to administer. Three studies were conducted to develop and validate the Tromsø Social Intelligence Scale (TSIS). Study 1 examined professional psychologists’ interpretations of social intelligence to derive a consensually agreed‐upon definition of the construct. In Study 2, a large pool of social intelligence items were tested, and a 3‐factor, 21‐item scale was identified. In Study 3, the stability of this measure was confirmed.
