算术策略运用能力的年龄差异：元认知监测与算术知识的作用

采用选择/无选法,以估算与精确心算为研究任务,考察了元认知监测与算术知识影响个体算术计算策略选择与执行的年龄相关差异。129名不同年龄儿童与成人被试参加实验。结果发现：（1）算术知识对儿童及成人的估算复杂策略有促进作用,并对提升他们心算策略运用的速度和减少错误有作用;（2）元认知监测显著影响儿童的估算策略选择,能够促进使用最佳策略;（3）算术知识在估算及心算策略执行的年龄差异方面起完全中介作用,元认知监测则在估算策略选择的年龄发展中起部分中介作用;（4）算术知识对元认知监测在估算及心算策略执行上的作用起完全中介作用,而对估算的策略选择则不存在中介作用,这表明元认知监测在估算策略选择上具有举足轻重的地位。     

Childhood abuse and depressive vulnerability in clients with gender dysphoria

Background: Childhood abuse in the early lives of gender variant people has been under‐reported, although higher psychiatric morbidity, particularly depression and suicidality, than in the general population is more widely recognised. There are increasing numbers of people seeking advice and treatment for gender dysphoria (GD) some of whose experiences of depression and childhood abuse may be additional treatment considerations. Aim: To illuminate the issues relating to childhood abuse, depression and GD via case examples underpinned by a summary review of the relevant literature, for their combined relevance to therapeutic practice and service provision. Methods: A review of relevant online literature was conducted and two case examples were developed subsequently to capture the core review themes from a practice perspective. Results: Nine studies met the inclusion criteria. Gender variant children and adolescents may experience abuse by peers and teachers, as well as parents and caregivers. Emotional abuse and neglect may have more adverse consequences than more active forms of abuse. Conclusions: This is an under‐researched area, and inconsistencies of design, definition, measurement and controls were evident in the literature. While no clear association between depressive vulnerability and childhood abuse could be found, prevalence of such abuse was high. A case is made for clients with GD to have the opportunity to explore the influence and meaning of their adverse childhood experiences on their social and psychological development, and for additional training and education for practitioners.     

Analogue Mental Transformations in 3‐Year‐Olds: Introducing a New Mental Rotation Paradigm Suitable for Young Children

Until now, a successful application of the mental rotation paradigm was restricted to children 5 years or older. By contrast, recent findings suggest that even infants can perform mental rotation. Unlike the methods used in infant studies (looking time), our new research paradigm allows for the measurement and interpretation of reaction times. Kindergartners (aged 3–6 years) were presented with a stimulus configuration on a touchscreen and asked to bring a rotated stimulus into an upright position using the shortest path. Mean reaction time (RT) increased linearly with angular disparity. The ensuing linear trend was significant not only for the entire sample but also for the youngest age group analysed separately. To exclude the possibility that linearity was due to movement planning, 3‐year‐olds had to manually rotate a stimulus about the same trajectory without the need for a corresponding mental transformation in a second experiment. Here, no linear trend was observed. These results are interpreted as evidence for an analogue mental transformation in 3‐year‐olds, equal to the transformation processes in older children's and adults' mental rotation.

独立预测作用,还是基础性影响？——价值观对集体行动的影响机制

为阐明价值观在集体行动参与中的地位和影响机制,研究者以利比亚事件为背景,针对现实和网络场域中不同程度的4类集体行动倾向,在天津市957名大学生中进行问卷调查研究,结果发现：价值观显著增加了低成本集体行动倾向解释率,并调节着情绪、工具性动机和社会认同对集体行动倾向的影响;中国人进行集体行动决策时具有集体主义理性计算特征;不同场域和程度的集体行动有其各自规律.结论：价值观在集体行动参与决策中是一种与社会认同类似的基础性变量.     

Is recursion language-specific? Evidence of recursive mechanisms in the structure of intentional action

In their 2002 seminal paper Hauser, Chomsky and Fitch hypothesize that recursion is the only human-specific and language-specific mechanism of the faculty of language. While debate focused primarily on the meaning of recursion in the hypothesis and on the human-specific and syntax-specific character of recursion, the present work focuses on the claim that recursion is language-specific. We argue that there are recursive structures in the domain of motor intentionality by way of extending John R. Searle’s analysis of intentional action. We then discuss evidence from cognitive science and neuroscience supporting the claim that motor-intentional recursion is language-independent and suggest some explanatory hypotheses: (1) linguistic recursion is embodied in sensory-motor processing; (2) linguistic and motor-intentional recursions are distinct and mutually independent mechanisms. Finally, we propose some reflections about the epistemic status of HCF as presenting an empirically falsifiable hypothesis, and on the possibility of testing recursion in different cognitive domains.     

Influence of character strengths on mental health stigma

We examined traits of open-mindedness, kindness, hope, and social intelligence in the context of mental health stigma. Stigma – a process that objectifies and dehumanizes a person who has mental illness – diminishes people’s ability to control their behavior as coping with stigma requires self-regulation. Exploring mental health stigma through the lens of character strengths allows for understanding individual differences and kinds of characteristics that help decrease the ramifications associated with stigma of mental health. Several tasks explored the effects of character strengths on implicit and explicit mental health stigma: implicit association task, measures of willingness to interact with those with a mental health disorder, and a social distance task of self, friend, and person with a disorder. Character strengths of social intelligence and kindness were indicative of less stigma of mental health. More open-minded individuals tended to not hold individuals diagnosed with a mental health disorder personally responsible for acquiring that disorder.     

Effects of testing on subsequent re‐encoding and long‐term forgetting of action‐relevant materials: On the influence of recall type

Testing one's memory of previously studied information reduces the rate of forgetting, compared to restudy. However, little is known about how this direct testing effect applies to action phrases (e.g., “wash the car”) – a learning material relevant to everyday memory. As action phrases consist of two different components, a verb (e.g., “wash”) and a noun (e.g., “car”), testing can either be implemented as noun‐cued recall of verbs or verb‐cued recall of nouns, which may differently affect later memory performance. In the present study, we investigated the effect of testing for these two recall types, using verbally encoded action phrases as learning materials. Results showed that repeated study–test practice, compared to repeated study–restudy practice, decreased the forgetting rate across 1 week to a similar degree for both noun‐cued and verb‐cued recall types. However, noun‐cued recall of verbs initiated more new subsequent learning during the first restudy, compared to verb‐cued recall of nouns. The study provides evidence that testing has benefits on both subsequent restudy and long‐term retention of action‐relevant materials, but that these benefits are differently expressed with testing via noun‐cued versus verb‐cued recall.     

Action orientation overcomes the ego depletion effect

It has been consistently demonstrated that initial exertion of self‐control had negative influence on people's performance on subsequent self‐control tasks. This phenomenon is referred to as the ego depletion effect. Based on action control theory, the current research investigated whether the ego depletion effect could be moderated by individuals' action versus state orientation. Our results showed that only state‐oriented individuals exhibited ego depletion. For individuals with action orientation, however, their performance was not influenced by initial exertion of self‐control. The beneficial effect of action orientation against ego depletion in our experiment results from its facilitation for adapting to the depleting task.
