工作记忆表征引导视觉注意选择的眼动研究

工作记忆表征能否引导视觉注意选择？目前实验结果尚不一致。有研究者认为能否观察到注意引导效应取决于视觉搜索类型。研究采用工作记忆任务与视觉搜索任务相结合的双任务范式, 结合眼动追踪技术, 对不同视觉搜索类型下的注意引导效应进行验证。实验1结果发现, 不管视觉搜索任务的靶子是否变化, 在早期的眼动指标上都发现了显著的注意引导效应, 但注意引导效应在靶子固定的视觉搜索任务下表现得更强。实验2在平衡两种视觉搜索任务中的工作记忆负载后发现, 两种视觉搜索任务下都出现了显著的注意引导效应, 但没有发现实验1中所出现的任务间差异。实验结果否定了视觉搜索类型对注意引导效应的决定性影响, 同时也提示工作记忆负载可能在注意引导效应中起重要作用。     

An ecological analysis of knowing by wielding.

The ecological approach to perception, as developed by James Gibson, is described and applied to how one knows, by means of the haptic perceptual system, various properties of hand-held objects. Four sets of experiments are reviewed in which subjects reported on the extent, orientation, shape, and fractional components of unseen objects wielded freely. For each task, an invariant specific to the object property in question is identified in the structured arrays of rotational moments and strains produced by the act of wielding. Results are discussed in relation to the concepts of attention and stimulation, as reformulated by the ecological approach, and the general theory of perception as information pickup.     

Applying the M-92, A Self-Knowledge Technique for Determining Job Aspirations and Expectations

The M-92 technique is aimed at helping teenagers become aware of: (a) the relationships between certain classic determinants such as prestige, income, and job opportunities and their system of job aspirations and/or expectations; (b) the strong and weak points in their system of information about jobs; (c) the internal structure of their system of occupational representations; and (d) possible conflicts in values or discordancies between aspirations and expectations. From a theoretical standpoint the M-92 draws directly on Coombs (1975) and Gottfredson (1981). Methodologically, it is an extension of the Hammond et al. (1988) Social Judgement Theory to the case of pair comparisons. Several concrete examples of the M-92 in use are described.     

超声引导和神经刺激仪定位在臂丛神经阻滞中的应用比较

臂丛神经阻滞广泛用于上肢手术,其成功的关键在于准确的解剖定位和局麻药的均匀扩散,神经刺激仪和超声技术应用于臂丛神经阻滞,改变传统方法的盲目性,更加安全有效。本文应用比较治疗学的观点,运用Meta分析方法,对两种方法辅助臂丛神经阻滞进行比较,指导科学合理的临床决策,发现超声引导更具优势,值得在临床推广。     

不同感觉通道的节奏感知及其交互作用

节奏感知是人类独有的认知现象, 听觉在节奏加工中具有优势, 声音节奏可以更好地与肢体运动同步, 但视觉和触觉通道在节奏感知上也有着各自特点并存在广泛的交互作用。视觉通道的节奏感知较弱, 与听觉节奏同时呈现时会受到时间定位上的拉扯, 但通过加入运动信息和增强后天经验可以得到强化; 节奏刺激可以调节注意在时间上的分配使其同步化, 这种调节作用可以单通道或者跨通道地出现; 触动觉与听觉联系紧密, 人们可以通过听触通道的整合对节奏进行高级加工。     

Parental Guidance and Children's Executive Function: Working Memory and Planning as Moderators During Joint Problem‐Solving

Cognitive aspects of children's executive function (EF) were examined as moderators of the effectiveness of parental guidance on children's learning. Thirty‐two 5‐year‐old children and their parents were observed during joint problem‐solving. Forms of guidance geared towards cognitive assistance were coded as directive or elaborative, and children's responses were recorded. Children were then assessed on an independent version of the same task. A parent‐rated composite of working memory and planning was used as a measure of EF. Directive guidance by parents was associated with more child errors during the joint activity, whereas elaborative guidance was associated with better performance. Parent‐rated EF moderated the relation, such that the relation between elaborative guidance and better performance was only significant for children with low EF. During the independent task, EF again moderated the relation between parent guidance and children's performance, such that children with low EF did worse when parents had provided more directive guidance; for children with high EF, directive guidance was associated with better independent performance. These findings suggest that the extent to which children's performance relates to different forms of parents' guidance varies, and elaborative assistance may be more helpful for children with low EF.

明代初期道德生活的政治导向

明代道德生活的偏执性,在中国历史上极其特殊的。追根溯源,是明代初期政治生活的特殊性所引发的。分封、废相、厂卫、教化、粮长等制度的改革与创设,不同程度地将社会道德生活引入了无以复加的偏执境地。     

The participation of children and adolescents in family counselling: The German experience

This paper reflects the experiences of young people in child guidance and family counselling. For this purpose, first the institutional background of these counselling services in Germany is outlined. The fact that the adolescents concerned feel partly excluded and insufficiently integrated into the counselling process is illustrated through qualitative analysis of the experiences 17 young people had during their counselling process. These empirical findings are critically discussed in terms of the institutional conditions and methodical approaches which counteract the involvement of the actual addressees of the counselling service. The paper concludes that professionals need to attend more to facilitating the participation of young people.
