社会合作信息对距离知觉的影响

为探讨社会合作信息对距离知觉的影响,本研究通过两个实验,采用动态追逐场景,对两个追逐者之间的交互模式(或合作或单独追逐同一目标)与追逐目标的存在与否进行了操作。结果发现,相比随机运动和单独追逐,存在合作关系的两个追逐者间的距离被知觉得更远,即存在距离的扩张效应(实验1),且该效应不能由底层的物理特征所解释(实验2)。该结果揭示,社会合作信息使得知觉距离被扩张,其可帮助理解视觉的适应性机制。

部总知识在解决加法文字题中的作用

探讨的问题是部总知识是否制约着算术文字题的解答过程。小学4年级学生(192人)和大学生(178人)被要求解答一步加法文字题。实验结果发现,正确列式方式受到已知客体集合具体特征的系统性影响,尤其是随着年龄的提高和练习程度的深入,这种影响越来越明显。这是部总知识作用假设所不能解释的。现根据集合在心理表征中的位置和表征强度解释结果,并在此基础上讨论了研究的实践意义。     

Pediatric topics in the school psychology literature: publications since 1981

Pediatric topics have potential importance to school psychology given the field's new, broadly conceived definition, reconceptualization of schools as health delivery sites, burgeoning pediatric knowledge with educational implications, and expansion of pediatricians' roles into behavioral realms. This article addresses the rate at which pediatric-related articles were published among school psychology journals (Journal of School Psychology, Psychology in the Schools, School Psychology International, School Psychology Review, and School Psychology Quarterly) from 1981 to 2001. The overall number of such articles increased from 11 during the 1981-1983 interval to more than twice as many during every subsequent 3-year interval. Articles, some reporting empirical findings and others offering reviews or practice suggestions, concerning traditional health conditions and attention deficit hyperactivity disorder (ADHD) appeared to be ample. Fewer articles concerned with school psychologists as health care providers and school psychologist-pediatrician collaboration were found. The available literature seems to support school psychologists' widening role definition.

Changes in positive and negative affect as predictors of change in felt age: Results from the Health and Retirement Study

The present study aimed to examine how changes in positive and negative affect and their interaction predict changes in felt age in a longitudinal design of two waves drawn from the Health and Retirement Study (HRS). Participants (n = 4174) at an average age of 67.97 completed the 2008 and 2012 left behind questionnaire of the HRS. Our results showed that an increase in positive affect and a decrease in negative affect from Wave 1 to Wave 2 predicted an accelerated decrease in felt age. There was an interaction effect showing that for those with an increase in negative affect, a higher change in positive affect predicted reduced odds for accelerated increase in felt age. To conclude, improving favorable change in the combination between positive and negative affect might in turn relate to the individual’s self-perceptions of aging, in the second half of life.     

Groups perform better than the best individuals on Letters-to-Numbers problems

Eighty-two four-person cooperative groups and 328 independent individuals solved a random coding of the letters A–J to the numbers 0–9. On each trial the group or individual proposed an equation in letters (e.g., A + D=?), received the answer in letters (e.g., A + D=B), proposed one specific mapping (e.g., A=3), received the answer (e.g., True, A=3), and proposed the full mapping of the 10 letters to the 10 numbers. As predicted, the groups had fewer trials to solution, proposed more complex equations, and identified more letters per equation than each of the best, second-best, third-best, and fourth-best individuals. We interpret the group superiority as due to the highly intellective nature of Letters-to-Numbers problems, which entail demonstrable recognition of correct answers, demonstrable rejection of erroneous answers, and multiple insights into effective collective information processing strategies.     

The influence of war on moral judgments about harm

How does war influence moral judgments about harm? While the general rule is “thou shalt not kill,” war appears to provide an exception to the moral prohibition on intentional harm. In three studies (n = 263, n = 557, n = 793), we quantify the difference in moral judgments across peace and war contexts, and explore two possible explanations for the difference. The findings demonstrate that third-party observers judge a trade-off of one life for five as more morally acceptable in war than in peace, especially if the one person is from an outgroup of the person making the trade-off. In addition, the robust difference in moral judgments across “switch” and “footbridge” trolley problems is attenuated in war compared to in peace. The present studies have implications for moral psychology researchers who use war-based scenarios to study broader cognitive or affective processes. If the war context changes judgments of moral scenarios by triggering group-based reasoning or altering the perceived structure of the moral event, using such scenarios to make decontextualized claims about moral judgment may not be warranted.     

Trajectories of sleep problems among adolescents after the Wenchuan earthquake: the role of posttraumatic stress disorder symptoms

Objective: We examined the trajectories of sleep problems in adolescents after the Wenchuan earthquake, and assessed predictors such as posttraumatic stress disorder symptoms. Methods: We surveyed adolescents at 1, 1.5, 2, and 2.5 years after the Wenchuan earthquake. In total, 391 adolescents completed self-report questionnaires. Results: We identified five latent sleep problem trajectories, specifically, U-shaped (3.8%), low-stable (68.0%), high-stable (10.8%), increasing (8.7%), and decreasing (8.7%) trajectories. Additionally, we found that posttraumatic stress disorder hyper-arousal symptoms were more frequent in individuals who had non-low-stable trajectories. Adolescents in the U-shaped group were less likely to have intrusive symptoms. Conclusion: After natural disasters, consequent sleep problems in adolescents do not remain stable over time, and sleep problem trajectories had considerable heterogeneity.
