速度知识和表征动量

通过3个实验探索速度知识和表征动量的关系。3个实验均使用2（速度知识：快、慢）×2（运动方向：左、右）的两因素实验设计,采用诱导运动范式,因变量为偏移加权均数。实验1使用汽车和自行车作为刺激材料,发现两者的前移量无差异;实验2使用人奔跑和站立姿势作为刺激材料,发现奔跑的前移量大于站立的前移量;实验3是控制实验,发现实验2的结果不是由水平视角差异造成的。结论：在有效启动速度概念的情况下,速度知识可以影响表征动量,但其影响可能相对微弱。     

Representational momentum in children born preterm and at term

The term representational momentum (RM) refers to the idea that our memory representations for moving objects incorporate information about movement – a fact that can lead us to make errors when judging an object’s location (the RM effect). In this study, we explored the RM effect in a sample of children born very prematurely and a sample born at term. Because preterm children are known to be at risk for problems with motion perception, we anticipated that they would show a weaker or absent RM effect. This prediction was confirmed. In addition, we found that, in both samples of children, 5–6 year olds showed a reduced RM effect compared to 7–9 year olds. These results demonstrate that the ability to represent motion information in memory shows continued development over this age range, and may help to elucidate factors contributing to problems with fine and gross motor planning and execution that have been observed in the preterm population. We propose that problems affecting the formation, maintenance, or use of predictive models, or motion extrapolation skills, may have cascading effects on the development of other abilities.     

Creativity and involvement in art in different types of synaesthesia

The aim of the present study was to test the relationship between different types of synaesthesia and their involvement in art, creative, and visual abilities. We tested 20 grapheme‐colour, 18 sound‐colour, 19 grapheme‐colour‐and‐sound‐colour, 20 sequence‐space synaesthetes, and the same number of controls matched by age, gender, and education. We assessed the number of artistic professions, involvement in art, and the performance in psychometric tests of divergent and convergent creativity, as well as visual and visuo‐spatial abilities. Results show a higher prevalence of artists among synaesthetes, especially sound‐colour synaesthetes. Sound‐colour synaesthetes also showed a higher involvement in artistic activities overall while sequence‐space synaesthetes showed higher involvement in visual art. Only grapheme‐colour‐and‐sound‐colour synaesthetes showed significantly higher divergent creativity compared to matched controls. Additionally, overall, synaesthetes scored higher in visuo‐spatial abilities (i.e., mental rotation). For synaesthetes and controls, visuo‐spatial abilities correlated with divergent creativity. We discuss that synaesthetes’ higher involvement in art is not necessarily reflected in their basic creative abilities.     

33-month-old children succeed in a false belief task with reduced processing demands: A replication of Setoh et al. (2016)

A recent low-inhibition false belief task showed a high success rate with 33-month-old children when response-generation demands were reduced [Setoh, Scott, & Baillargeon (2016). Proceedings of the National Academy of Sciences, 113(47), 13360–13365]. We found correct responding in 74% of N = 58 33-month-old children, replicating the original findings. Within the same sample, we compared this performance with performance in a concurrent measure of false belief understanding which has previously produced competence in children below the age of 3 years [Hughes & Ensor (2007). Developmental Psychology, 43(6), 1447–1459]. Contrasting sharply with findings from the low-inhibition false belief task, we found partial competence in 15%, and full competence in only 5% of the same sample. These results show that the paradigm by Setoh and colleagues generates reliable findings in a different lab and a different language. We discuss this pattern of results in relation to theoretical considerations of early false belief understanding.     

Differential ability antecedents of general and specific dimensions of declarative knowledge: More than g

The purpose of the current study is to test the proposition that the relative contribution of narrow abilities (but not of g) may have been obscured in prior research due to a failure to employ fully multidimensional latent variable analyses. The current study corrects for these deficiencies and examines the relationships between cognitive abilities and domain-specific declarative knowledge. Results show that when observed criterion test scores were individually regressed on abilities, only g was consistently related to the criteria. However, when a latent variable analysis was applied to the same data, both g and narrow ability factors accounted for substantial portions of variance in different latent criterion constructs. Implications are discussed.     

Association of Behavioral Self-Regulation with Concurrent Functional Capacity Among Stroke Rehabilitation Patients

The purpose of this study was to test the hypothesis that the Behavioral Dyscontrol Scale (BDS), a measure of the executive cognitive capacity to use an intention to guide purposeful, goal-directed activity would be strongly associated with concurrent functional status after controlling for age, sex, education, severity of pain, medical comorbidity, depression, and general mental status, in a sample of 246 elderly inpatients receiving rehabilitation services following hospitalization for stroke. Functional status was assessed by rehabilitation nurses' ratings of patients on 11 ADL items and on the Barthel Index. The BDS was the strongest predictor for 11 of the 12 dependent variables. Although it correlated significantly with all outcomes, the MMSE entered only one of the regression models. Of the other covariates, only age and severity of pain made an additional contribution to the prediction of functional ability for more than 1 dependent variable. Consistent with prior results in several other samples, the ability to use intentions to guide purposeful behavior appears to be an important contributor to everyday functioning among older adults.     

中学生自我觉知的日常问题解决能力研究

采用问卷法对907名中学生自我觉知的日常问题解决能力进行研究。结果表明,自我觉知的日常问题解决能力存在显著的领域差异;对不同领域的日常问题,初中生与高中生自我觉知的能力有不同的差异模式,我向思维会导致初中生在某些领域高估其能力水平;性别差异以及独生与非独生子女差异在多项能力评估中显著存在;大多数自我觉知能力与自评健康状况、家庭经济状况、自评外在形象、做家务事的次数及父母管教严格程度有显著的正相关。

The relations between preferences for using abilities, self-estimated abilities, and measured abilities among career counseling clients

The present research investigated the relations among the declared preferred degree for using career-related abilities in one’s future career, self-estimates of these abilities, and measured abilities in a sample of 201 career-counseling clients. The highest correlations (range .57-.65) were found between the preferred degree for using an ability and the self-estimates of the ability. However, the direction of the gap between self-estimates and preferred degree of use varied among clients and among abilities. Clients also varied in the pattern of differences between their measured abilities and self-estimates, with 69% of the clients overestimating their abilities, while only 9% underestimated them. The hypothesis that self-estimate mediates the relation between one’s preference for using an ability and the respective measured ability was supported. The correlation between a client’s measured ability and preferred degree of use was higher among clients with a fairly accurate self-estimate than among those whose self-estimates were biased. Implications for research and counseling are discussed.     

Ongoing development of social cognition in adolescence

Age differences in social cognition between adolescents and young adults were investigated. Two large groups of adolescents and young adults were given tasks of theory of mind and emotion recognition. In addition, to control for possibly related basic cognitive development, working memory, speed of processing, and verbal ability were assessed. A strong age effect was revealed across both measures of social cognition. Adolescents performed with a lower accuracy than adults. Further analyses indicated that those age differences remained significant even after controlling for basic cognitive abilities. Exploratory analyses indicated no influence of pubertal phase on social cognition. Results suggest ongoing development of social cognition across adolescence, independent of individual differences in more basic cognitive abilities.
