The relationship of environmental concern with public and private pro-environmental behaviours: A pre-registered meta-analysis

Previous meta-analyses identified a gap between environmental concern and pro-environmental behaviours. However, the failure to differentiate these behaviours and the influence of contextual factors may limit understanding of the gap. This pre-registered meta-analysis evaluated the magnitudes of the correlations of environmental concern, as measured by the New Environmental Paradigm of thinking, with public and private pro-environmental behaviours and investigated the moderating roles of sociocultural contexts. Environmental concern was found positively correlated with public pro-environmental behaviour (k = 10, N = 4636; r = 0.27) and private pro-environmental behaviour (k = 31, N = 20,907; r = 0.35). These two pooled correlations did not differ significantly. Institutionalization of environmental protection did not moderate these correlations, while cultural factors, including individualism, long-term orientation, and external control, did. These findings maintain the utility of environmental concern in facilitating different pro-environmental behaviours and highlight the lack of research attention on public pro-environmental behaviour.     

分配注意与发音抑制对视觉工作记忆的影响

本研究通过两个实验考察了分配注意与发音抑制对视觉工作记忆再认能力的影响.结果表明,保持阶段的分配注意与编码阶段的分配注意相比,对视觉工作记忆成绩影响更大;双任务条件下,被试正确回忆言语刺激时,视觉作业的正确率高,而错误回忆言语刺激时,视觉作业的正确率会降低;发音抑制与视觉工作记忆成绩无关.     

躯体表情与面部表情加工进程比较

躯体和面孔是个体情绪识别的敏感线索。与面部表情的早期视觉加工相似, P1成分对恐惧、愤怒等负性躯体表情更加敏感, 反映了对躯体威胁信息快速且无意识的加工。情绪躯体和面孔还有着类似的构型加工, 表现为二者都能诱发颞枕区视觉皮层相似的N170成分, 但涉及的神经基础并不完全相同。在构型编码加工中, 面部表情的N170与顶中正成分(Vertex Positive Potential, VPP)较躯体表情的N170、VPP更加明显。在面部表情和躯体表情的后期加工阶段, 早期后部负波(Early Posterior Negativity, EPN)反映了面孔和躯体视觉编码的注意指向加工, 随后出现的P3与晚期正成分(Late Positive Component, LPC)代表了顶额皮层对复杂情绪信息的高级认知加工。躯体表情还存在与外纹状皮层躯体区相关的N190成分, 其对躯体的情绪和动作信息敏感。今后的研究应进一步探讨动作对情绪知觉的影响、动态面孔−躯体情绪的加工机制等。
