无关工作记忆表征的负性情绪信息能否捕获视觉注意?一项眼动研究

研究通过分析视觉搜索任务的首次注视点和行为反应时, 探讨无关工作记忆表征的负性情绪信息对视觉注意选择的影响。实验1发现在反映早期注意选择的首次注视点百分率指标上, 不管工作记忆表征的情绪效价如何, 均出现了显著的注意捕获效应; 实验2发现当采用中性情绪靶子刺激时, 首次注视点百分率指标上仍表现出了稳健的注意捕获效应; 在首次注视点持续时间指标上, 实验1和实验2均发现记忆匹配条件的干扰刺激显著小于控制条件的干扰刺激, 表现出注意的快速脱离; 而在行为反应时指标上, 早期的注意捕获效应消失(实验1), 甚至被反转为注意抑制效应(实验2)。这些结果表明在早期注意选择阶段, 记忆驱动的注意捕获效应不受工作记忆表征情绪效价的影响, 但认知控制会在早期注意捕获之后促使注意快速脱离记忆匹配的干扰刺激, 其作用效果受靶子刺激情绪效价的调节。     

Parenting and Chinese Adolescent Suicidal Ideation and Suicide Attempts: The Mediating Role of Hopelessness

Various family factors are risk factors for adolescent suicidality (suicidal ideation and suicide attempts). However, little is known about the role of parenting in adolescent suicidality. The present study examined the unique relations between three parenting dimensions (parental warmth, behavioral control, and psychological control) and adolescent suicidality, as well as the mediating role of adolescent hopelessness among these relations. A total of 1529 Chinese adolescents (52 % male; mean age = 14.74 years, SD = 1.48) completed anonymous questionnaires designed to assess three parenting dimensions, hopelessness, suicidal ideation and suicide attempts. After controlling for gender, age, family structure, and socioeconomic status, it was found that parental warmth negatively predicted adolescent suicidality, whereas psychological control positively predicted adolescent suicidality. In addition, parental warmth negatively predicted adolescent hopelessness, whereas psychological control positively predicated adolescent hopelessness, which in turn enhanced adolescent suicidality. Although behavioral control did not predict adolescent suicidality, it did negatively predict adolescent hopelessness, which in turn promoted adolescent suicidality. These findings revealed the differential roles of different parenting dimensions in adolescent suicidality, and the mediation effect of adolescent hopelessness between parenting and adolescent suicidality. Future practices would benefit from incorporating both parenting and hopelessness for optimal intervention effect.     

工作记忆表征的激活与抑制状态对注意引导效应的影响

本研究采用双任务范式, 通过定向遗忘任务操纵工作记忆表征状态, 分别在目标无关和目标相关条件下考察工作记忆激活与抑制状态对视觉搜索早期注意引导效应的影响。实验1与实验2发现当工作记忆表征只可能与视觉搜索分心物匹配时(目标无关条件), 处于激活状态的工作记忆表征会引导视觉注意偏向到与之匹配的分心物, 表现出注意引导效应, 而处于抑制状态的工作记忆表征则没有观察到注意引导效应。实验3与实验4发现, 当工作记忆表征有可能与视觉搜索目标匹配时(目标相关条件), 处于激活状态的工作记忆表征能捕获注意, 而处于抑制状态的工作记忆表征只有与视觉搜索目标匹配时, 才表现出对该搜索目标反应的延迟。这些研究的结果表明(1)处于激活状态的工作记忆表征能有效地引导注意偏向到与之匹配的搜索目标或分心物, 并且这种注意引导效应并未受到抑制动机的影响而被消除或反转; (2)处于抑制状态的工作记忆表征能将抑制状态传递到视觉搜索阶段, 并延迟对与之匹配的搜索目标的反应。     

The effects of receptive and expressive instructional sequences on varied conditional discriminations

Many Early Intensive Behavioral Intervention (EIBI) curricula recommend teaching receptive responding before targeting expressive responding (Leaf & McEachin, 1999; Lovaas, 2003). However, a small literature base suggests that teaching expressive responses first may be more efficient when teaching children with ASD and other developmental disabilities (Petursdottir & Carr, 2011). The present study employed an alternating treatments design to compare the effects of three instructional sequences to teach feature, function, and class to three children diagnosed with ASD: (a) receptive–expressive, (b) expressive–receptive, and (c) mixed. The results suggested that expressive–receptive was the most efficient training sequence for all three participants. Additionally, greater emergent responding was observed with the expressive–receptive training sequence.     

The effects of incubation temperature on the development of the cortical forebrain in a lizard

The embryos of egg-laying species are exposed to variable thermal regimes, which can influence not only the resultant hatchling’s morphology (e.g., size, sex) and performance (e.g., locomotor speed), but also its cognitive performance (learning ability). To clarify the proximate basis for this latter effect, we incubated eggs of the scincid lizard Bassiana duperreyi under simulated ‘hot’ and ‘cold’ natural nest temperatures to examine the effect of incubation temperature on the structure of the telencephalon region of the forebrain. Hatchlings from low-temperature incubation had larger telencephalons (both in absolute terms and relative to body size) and larger neurons in their medial cortices, whereas the medial cortices of hatchlings from high-temperature incubation had fewer neurons overall, but greater neuronal density, and more neurons in certain areas. These temperature-induced differences in B. duperreyi forebrain development are consistent with (and may explain) the disparities in learning ability between hatchlings from our two incubation treatments. The phenotypic plasticity of lizard telencephalon anatomy in response to incubation temperature presents exciting opportunities for studies on the evolutionary and developmental determinants of intelligence in vertebrates, but also offers a cautionary tale. Global climate changes, wrought by anthropogenic activities, may directly modify brain structure in reptiles.     

初中生外在学习动机内化的心理机制研究

本研究假设在从事无趣活动时以自主支持方式提供的外部理由动机策略,能够增加参与者对所从事无趣活动任务价值的认同经验,认同经验的程度将会预测后来努力的程度.因此我们测试了努力理由→认同经验→努力的动机中介模型.另外,我们意识到也可能还存在其他动机中介模型,因此我们进一步验证了两个选择模型:努力理由→重要性→自我决定感→努力;努力理由→努力.     

青少年心理一致感水平及其与应付方式的关系

本研究以265名高中生为被试,探讨青少年心理一致感发展的特点以及与应付方式的关系。研究结果表明,(1)被试在心理一致感发展水平上存在显著的年级差异;(2)三个年级被试的应付方式存在显著的差异;(3)被试心理一致感水平与问题解决、求助两种应付方式存在显著的正相关;(4)被试心理一致感水平与自责、幻想、退避、合理化四种应付方式存在显著的负相关。高心理一致感个体在压力调节上倾向于采用成熟而积极的应付方式。本研究从压力应对的过程角度分析心理一致感与应付方式之间的关系。     

环境问题研究的社会学理论——日本学者的研究

纵观日本环境问题的发展历史,我们发现,不同的时期环境问题的种类和表现形式不同,因此,学者在研究环境问题时所采用的视角也不同,由此所产生的环境问题研究的理论也不同.根据以往的研究,可以把日本的环境问题的历史分为公害开发问题期和环境问题普遍化期.日本学者从致害论、受害论和解决论等三种不同的视角对日本的公害环境问题进行研究,建立了不同的环境社会学理论.作为公害开发问题期所建立的理论有受益圈/受害圈理论、受害结构论和生活环境主义;作为环境问题普遍化期所建立的理论有社会两难论、公害输出论和环境控制系统论.我国目前正处在日本曾经经历的公害开发问题期,同时还面临着日本环境问题普遍化期的一些问题.因此,在两个不同时期所形成的日本环境社会学的理论对当今我国的环境问题的研究都具有重要的借鉴意义.     

当代西方德性伦理视野中的德性教化及其启示

自古以来,德性教化是西方伦理学中的重要课题。尤其进入20世纪50、60年代之后,西方德性伦理的复兴使人们重新审视德性教化。在当代西方德性伦理学家看来,德性已然失落。他们从实践教化和理论教化两个方面展开研究,深化了人们对德性教化的认识,为现代社会中德性教化的研究提供了有益的启示。     

太谷圣果寺大殿水陆壁画考释

山西晋中太谷县城西南约4公里的中咸阳村西北有一座寺院名曰"圣果寺",县志记载"圣果寺在县南十里东咸阳村,金皇统八年建"[1],民国太谷县志中记载此寺建于东咸阳村,但实际所处为中咸阳村,此外还有南、西、东三个咸阳村,与县志记载有出入,北咸阳村应当曾经有过设置。
