家庭环境与高中生发展:自主的中介作用及其性别差异

从浙江省三所全日制高中选取348名高一到高三的学生为被试, 采用集体上机填答的方式实施问卷调查, 考察家庭环境对高中生发展的影响及作用机制, 探讨自主的中介作用及其性别差异。使用描述检验、相关分析和结构方程模型等方法, 结果发现:(1)男生的情感自主显著高于女生, 感知到的家庭亲密度水平显著低于女生;(2)家庭环境和自主与积极发展呈显著正相关, 与消极发展呈显著负相关, 积极发展与消极发展呈显著负相关;(3)家庭环境对积极发展有显著的正向预测作用, 对消极发展有显著的负向预测作用, 且对积极发展的预测作用显著高于消极发展;(4)总体上, 自主在家庭环境和高中生积极、消极发展的关系中起显著的中介作用;自主在家庭环境和积极发展间的中介作用在男生和女生样本中均达到显著水平, 而在家庭环境和消极发展间的中介作用在男生样本中为完全中介, 在女生样本中不显著。研究结果为从家庭角度促进高中生的积极发展、降低消极发展的可能性提供了依据。

工作记忆刷新训练改善抑郁倾向大学生情绪调节能力的HRV证据

根据流调中心用抑郁量表(CES-D)和贝克抑郁量表(BDI-II-C)的得分情况招募健康被试20例, 抑郁倾向被试40例, 以自愿参加的分组方式将抑郁倾向被试分为工作记忆刷新训练组和对照组, 每组20例。对训练组进行为期20天的工作记忆刷新训练, 对照组不做处理。记录各组被试在前后测的刷新功能以及在情绪调节任务中量表的得分情况, 并收集各组被试在5种实验条件下的心率变异性(HRV)的频域指标值, 结果发现：前测时抑郁倾向个体的HF-HRV显著低于健康个体的平均水平。经过工作记忆训练, 后测的抑郁倾向训练组在情绪调节任务中的HF-HRV水平有显著的提高, 贴近健康对照组的水平, 并与抑郁倾向对照组分离。研究表明, 工作记忆刷新训练能够使抑郁倾向大学生的HRV活动更接近健康被试的HRV活动, 表明抑郁倾向大学生的情绪调节能力得到了改善。     

Learning in honey bees with brain lesions: how partial mushroom-body ablations affect sucrose responsiveness and tactile antennal learning

Honey bees are ideal organisms for studying associative learning, because they can rapidly learn different sensory cues, even under laboratory conditions. Classical olfactory learning experiments have shown that the mushroom bodies (MBs), a prominent neuropil of the central nervous system of the bee, are involved in olfactory learning and memory formation. We tested whether the MBs are also involved in tactile antennal learning. As in olfactory learning, bees use the antennae during tactile learning to sense tactile cues. We produced specific MB ablations by applying the mitotic blocker hydroxyurea (HU). In Drosophila, HU-induced brain lesions of the MBs strongly impaired olfactory memory formation. As treatment with HU might also interfere with the processing of the reward stimulus, sucrose, we measured the responsiveness to sucrose stimuli in these bees. Treatment with HU led to partial ablations of the median MB sub-units on one or both sides of the brain. We analysed side-specific effects in double-blind tests, testing sucrose responsiveness separately for each antenna, and conditioning first one antenna and then the other in a reversal learning assay. HU-treated bees without detectable ablations were less responsive to sucrose and had a poorer learning performance than untreated controls. Partial MB ablation did not additionally affect responsiveness to sucrose or tactile antennal learning. Interestingly, bees with bilateral MB ablations did not differ from untreated controls in their learning performance during the first learning phase. During reversal learning, acquisition in these bees was significantly lower than that in untreated controls. It is concluded that HU treatment affects sucrose responsiveness and tactile learning even without detectable ablation of neuropils. The effects of MB ablations on tactile learning are not side-specific and not correlated with the volume of the ablated neuropil.

Educational and Vocational Aspirations of Minority and Female Students: A Longitudinal Study

This study examined the relative importance of school, family, personal/psychological, race, and sex variables in predicting educational and vocational aspirations. A nationally representative sample of 10th‐grade students was followed through 2 years beyond their high school. Results suggested that sex and race significantly predicted educational and vocational aspirations of students. The educational aspiration model was shown to be more robust than the occupational aspiration model. Overall, students showed increases in educational and occupational aspirations, regardless of sex and race. Compared with other groups, Asian Americans had the greatest increase in educational aspirations. Female students, on the average, had higher educational and vocational aspirations.     

古代预测文化对科学认知的负面影响

我国古代预测文化观念大多属于假言推理的预 卜学,谈不上真正意义上的预测科学。但是其预测 的文化观念深刻地影响着一部分人的社会实践活 动,使一些人当作认知事物的演算工具,试图从中 寻找自然现象和社会现象的未知迹象。由于其预测 观念不是建立在科学的知识体系基础上,不能经过 实践反复检验,只是用偶然性判断社会现象的必然 性,用单一模式去解释错综复杂的社会现象,难免

论人、我、自然的和谐发展:疫情的社会心理学反思

新型冠状病毒疫情的预防和控制不仅是一个科学技术的问题,还是一个人文社会科学的议题。从社会心理学的视角来看,新型冠状病毒疫情的发生、蔓延是人与自然、人与他人以及人与自己的关系失调的体现。他人、自我、自然的和谐是社会和谐发展的前提和保证。培育好自尊自信、理性平和、亲善友爱的良好社会心态,把握好物质与精神、自由与规范、统筹与协作平衡发展的社会治理方法,可以在疫情的预防和控制中起到重要作用。
