弱智儿童心理旋转的研究

该研究探讨了一组9~12岁弱智儿童的“心理旋转”能力,该组儿童平均年龄10.1岁,平均智商（IQ）53.8（中度智力残疾）。研究结果与正常儿童（均龄8岁）作了比较。结果显示,弱智儿童的心理旋转能力明显较之正常儿童为差,智力缺陷对视觉图形空间定向能力（心理旋转）有着明显的影响。但无论弱智儿童或是正常儿童的结果均未发现性别差异。     

Absolute power leads to absolute corruption? Impact of power on corruption depending on the concepts of power one holds

Power has long been linked to the stigma of corruption. Three studies indicated that different power concepts have different implications for corruption behavior and perception. The personalized power concept relates to using power to pursue self‐centered goals for one's own benefit, whereas the socialized power concept relates to using power to pursue other‐focused goals for benefiting and helping others. Three studies were conducted to explore the effect of these two types of power concepts on corrupt intention or practice. The power concepts were measured in Study 1, primed through previous experience in Study 2, and utilized within a specific context in Study 3, respectively. Taken together, the three studies indicate that the personalized (vs. socialized) power concept increases (vs. decreases) self‐interested behavior and tolerance towards others' (especially high‐position others') corrupt practices.     

Cross-level moderating effects of Conscientiousness on within-person relationships of self-efficacy to effort allocation

Studies examining within-person level self-efficacy effects on effort allocation have produced mixed results, ranging from positive, to null, to negative. Drawing on individual differences literature, we propose that the within-person relationship between self-efficacy and effort allocation depends on Conscientiousness, a personality trait reflecting the will to achieve and capacity to self-discipline. Individuals with higher levels of Conscientiousness will respond to lower self-efficacy with increased effort, resulting in an inverse relationship between self-efficacy and effort expenditure. In contrast, individuals with lower levels of Conscientiousness will need higher self-efficacy to stay task focused and sustain effort allocation, leading to a positive effect of self-efficacy on effort expenditure. Findings from a 3-week daily diary study generally support the hypothesized moderating effects of Conscientiousness. Theoretical and practical implications are discussed.     

A monolingual mind can have two time lines: Exploring space-time mappings in Mandarin monolinguals

Can a mind accommodate two time lines? Miles, Tan, Noble, Lumsden and Macrae (Psychonomic Bulletin & Review 18, 598–604, 2011) shows that Mandarin-English bilinguals have both a horizontal space-time mapping consistent with linguistic conventions within English and a vertical representation of time commensurate with Mandarin. However, the present study, via two experiments, demonstrates that Mandarin monolinguals possess two mental time lines, i.e., one horizontal and one vertical line. This study concludes that a Mandarin speaker has two mental time lines not because he/she has acquired L2 English, but because there are both horizontal and vertical expressions in Mandarin spatiotemporal metaphors. Specifically, this study highlights the fact that a horizontal time line does exist in a Mandarin speaker’s cognition, even if he/she is a Mandarin monolingual instead of a ME bilingual. Taken together, the evidence in hand is far from sufficient to support Miles et al.’s (2011) conclusion that ME bilinguals’ horizontal concept of time is manipulated by English. Implications for theoretical issues concerning the language-thought relationship in general and the effect of bilingualism on cognition in particular are discussed.     

Student Misbehavior in Hong Kong: The Predictive Role of Positive Youth Development and School Satisfaction

This study examined the predictive influences of positive youth development and school satisfaction on student misbehavior. The respondents were 1652 Grade 7 students (738 boys and 912 girls) recruited from 13 secondary schools in Hong Kong. Data was collected by a set of validated questionnaires. A predictive model was tested and developed by using structural equation modelling. The results showed that positive youth development (characterized by social competence, emotional competence, cognitive competence, behavioral competence, moral competence, recognition for positive behavior, beliefs in the future, and prosocial norms) positively influenced school satisfaction and reduced student misbehavior. School satisfaction significantly mediated the predictive effect of positive youth development on student misbehavior, particularly among girls. Girls reported having significantly higher levels of school satisfaction, moral competence, prosocial norms, and recognition for their positive behavior, while boys reported having significantly more frequent misbehavior. Off-task disruptive behavior was the most frequent misbehavior among students in Hong Kong. These findings contribute to research on positive youth development, quality of school life and student wellbeing, particularly in the Chinese context. Future research and practical implications for fostering students’ psychosocial competence and school satisfaction for preventing misbehavior were discussed.     

Curious Objects: How Visual Complexity Guides Attention and Engagement

Some things look more complex than others. For example, a crenulate and richly organized leaf may seem more complex than a plain stone. What is the nature of this experience—and why do we have it in the first place? Here, we explore how object complexity serves as an efficiently extracted visual signal that the object merits further exploration. We algorithmically generated a library of geometric shapes and determined their complexity by computing the cumulative surprisal of their internal skeletons—essentially quantifying the “amount of information” within each shape—and then used this approach to ask new questions about the perception of complexity. Experiments 1–3 asked what kind of mental process extracts visual complexity: a slow, deliberate, reflective process (as when we decide that an object is expensive or popular) or a fast, effortless, and automatic process (as when we see that an object is big or blue)? We placed simple and complex objects in visual search arrays and discovered that complex objects were easier to find among simple distractors than simple objects are among complex distractors—a classic search asymmetry indicating that complexity is prioritized in visual processing. Next, we explored the function of complexity: Why do we represent object complexity in the first place? Experiments 4–5 asked subjects to study serially presented objects in a self-paced manner (for a later memory test); subjects dwelled longer on complex objects than simple objects—even when object shape was completely task-irrelevant—suggesting a connection between visual complexity and exploratory engagement. Finally, Experiment 6 connected these implicit measures of complexity to explicit judgments. Collectively, these findings suggest that visual complexity is extracted efficiently and automatically, and even arouses a kind of “perceptual curiosity” about objects that encourages subsequent attentional engagement.     

A Slippery Myth: How Learning Style Beliefs Shape Reasoning about Multimodal Instruction and Related Scientific Evidence

The learning style myth is a commonly held myth that matching instruction to a student's “learning style” will result in improved learning, while providing mismatched instruction will result in suboptimal learning. The present study used a short online reasoning exercise about the efficacy of multimodal instruction to investigate the nature of learning styles beliefs. We aimed to: understand how learning style beliefs interact with beliefs about multimodal learning; characterize the potential complexity of learning style beliefs and understand how this short exercise might influence endorsements of learning styles. Many participants who believed in the learning style myth supported the efficacy of multimodal learning, and many were willing to revise their belief in the myth after the exercise. Personal experiences and worldviews were commonly cited as reasons for maintaining beliefs in learning styles. Findings reveal the complexity of learning style beliefs, and how they interact with evidence in previously undocumented ways.     

Social attention across borders: A cross-cultural investigation of gaze cueing elicited by same- and other-ethnicity faces

The gaze-cueing effect is a robust phenomenon which illustrates how attention can be shaped by social factors. In four experiments, the present study explored the interaction between the ethnic membership of the participant and that of the face providing the gaze cue. Firstly, we aimed to further investigate the differential impact of White, Black, and Asian faces on the gaze-cueing effect in White individuals. Secondly, we aimed to explore, for the first time, the impact of faces belonging to different ethnicities on gaze cueing in Chinese participants. The results allowed to rule out alternative accounts and showed that White participants exhibit a gaze-cueing effect for White and Asian faces, but not for Black faces, consistent with previous studies. As regards Chinese participants, the overall findings suggested a stronger gaze-cueing effect for White faces than for Asian faces. The results are discussed with reference to differences in the perceived social status of the various groups, pointing to the need of taking into account different cultural contexts.
