Hemispheric asymmetry effects in children studied by dichotic listening and visual half-field testing

Dichotic listening (DL) and visual half-field (VHF) testing were used to study hemisphere asymmetry in a developmental perspective. Five-, 8-, and 11-year-old children were presented lists of fused words using a DL technique in Experiment 1, and 8- and 11-year-old children were presented pictures of common objects using a VHF technique in Experiment 2. In both experiments, measures of identification, free recall, and recognition of the words/pictures were employed. The results revealed effects of ear input (right-ear advantage) and half-field presentation (right visual half-field advantage) for all age groups, although the magnitude of this lateralization effect differed between the three memory measures. The results are discussed in relation to developmental aspects of language laterality, and in relation to the clinical utility of non-invasive lateralization techniques.     

Learning a two-cue inference task when one of the cue-criterion relations is known

Learning two-cue probability learning (MPL) tasks when the functional relation between the first cue and the criterion was known to the subject was studied in a factorial experiment. Contrary to the predictions from a hypothesis sampling model assuming independent learning of each cue in MPL, the function form for the first cue was found to affect learning of the second cue, facilitating it when the functional relations were the same for both cues and inhibiting it when the functions were different. These results suggest that it is not possible to extrapolate findings from single-cue probability learning directly to MPL.     

回忆任务对合作抑制和错误修剪的调节——情绪效价和编码水平的影响

前人在项目回忆条件的合作记忆研究中记录到明显的合作抑制和错误修剪,背景提取条件的相关研究尤显不足;同时,情绪效价和编码水平对两类现象调节的研究尚未涉及。为此,本文在两个实验中采用经典合作记忆研究范式,以不同情绪效价的词汇为实验材料并以词汇在学习阶段的呈现颜色为背景展开研究。实验1和实验2分别在学习阶段采用了深编码和浅编码任务,回忆阶段则均含项目回忆(回忆已学词汇)和背景提取(回忆词汇在学习阶段的呈现颜色)两种任务。采用深编码条件的实验1的结果显示,项目回忆比背景提取条件的合作抑制更强、错误修剪更弱,回忆任务与词汇情绪效价交互影响合作抑制强度;采用浅编码条件的实验2则发现错误修剪在两种任务间的差异不显著。两实验的联合分析显示,回忆任务与编码水平交互影响合作抑制和错误修剪强度。上述结果表明:回忆任务对合作抑制和错误修剪的调节支持双重加工模型;回忆任务与情绪效价对合作抑制强度的交互影响支持权衡说,且与双重加工模型相吻合;回忆任务与编码水平交互影响合作抑制和错误修剪强度。     

Emotion Regulation in At‐Risk Preschoolers: Longitudinal Associations and Influences of Maternal Histories of Risk

Emotion regulation is a key challenge of early childhood. The present study examined emotion regulation behaviour longitudinally from infancy to preschool. The continuity of emotion regulation was explored within the larger ecological context of maternal childhood histories of aggression and social withdrawal and maternal use of constructive and non‐constructive behaviours. Forty‐five mothers with childhood histories of aggression or social withdrawal from the Concordia Longitudinal Risk Project, a prospective, longitudinal, intergenerational study, participated with their preschool children. Infants' emotion regulation behaviour was observed during interactions with their mothers when they were 5½ months of age. Emotion regulation in these same children as preschoolers was coded during an interference task using the Preschooler Self‐Regulatory Scheme. Longitudinal findings demonstrated continuity in children's use of emotion regulation behaviours from infancy to preschool. Higher maternal childhood histories of risk, specifically social withdrawal, contributed to the prediction of preschoolers' increased attention‐seeking behaviours. Mothers' use of non‐constructive verbalizations predicted more maladaptive styles of emotion regulation in their preschoolers. The findings highlight the importance of helping children develop adaptive emotion regulation skills from a young age and have implications for the design of preventive intervention programmes to help parents foster children's emotion regulation abilities.

心理资本: 本土量表的开发及中西比较

开发了本土心理资本量表, 并将之与西方量表进行了比较。结果显示, 本土心理资本构念具有二阶双因素结构: 事务型心理资本(自信勇敢、乐观希望、奋发进取与坚韧顽强)与人际型心理资本(谦虚诚稳、包容宽恕、尊敬礼让与感恩奉献)。事务型心理资本与西方心理资本基本相似, 人际型心理资本则具有本土文化气息。本土量表具有良好的效标关联效度, 人际型心理资本、事务型心理资本和任务绩效、周边绩效、工作满意度、工作投入及组织承诺显著正相关, 人际型心理资本与传统性、相依我正向关系显著。相比西方量表, 本土量表的信效度更好, 对工作绩效有更强的解释能力, 尤其是对周边绩效。建议进行心理资本研究时应充分考虑中西文化差异, 对组织而言, 则应重视对雇员本土心理资本各要素的开发与管理。     

专业社会工作介入社会性突发事件精神救助限制与突破

精神救助与物质救助一样.是社会性突发事件处置中一个当然的组成部分.在我国现实国情下,专业社会工作介入社会性突发事件精神救助在其理论研究与实践过程中都会暂时存在较难逾越的屏障.面对社会接受和专业自身发展所表现出来的诸多限制,专业社会工作要成功地介入社会性突发事件精神救助,发挥其优势作用,政府重视是前提,社会工作服务的本土化是根本,专业队伍建设是关键,积极行动是途径.

Ethics in construction project briefing

The research reported in this paper set out to investigate ethics in the initial stages of construction projects. Briefing is the first real contact stage between the commissioner (client/employer) of a project — at this stage a potential project — and those involved in project realization — the designers and, subsequently, the constructors. It is well known that early decisions are of greatest impact and so, the importance of the initial contacts, communications and consequent decisions are paramount. Different project participants are known to pursue individual objectives to varying degrees as well as possessing different perspectives and perceptions and operating/behaving in different ways. Hence, determination of the appropriate form, content etc. of a project is, inevitably, a matter of exercising value judgements and compromises and so, involves ethical considerations. A case study of a project through the briefing stage is reported and analysed, from initial contacts to scheme approval. It is apparent that a number of ethical concerns are manifest through the various actions of the major participants. An earlier version of this paper was presented at the “Ethics and Social Responsibility in Engineering and Technology” meeting, New Orleans, 2003.     

Conditioned water affects pair formation behaviour in the marine polychaete Neanthes (Nereis) acuminata

Assessing cues from conspecifics is paramount during mate choice decisions. Neanthes acuminata is a marine polychaete with a unique life cycle: pair formation, female death following reproduction, male parental care and male ability to mate again after egg care. Males completing such egg care are ‘experienced’. Females have been shown to prefer experienced males over all others, including aggressively dominant males. As the female dies following reproduction, the reproductive success of her offspring depends upon successful parental care by the male. It is therefore vital that the female makes a good mate choice decision. This paper shows that the use of conditioned water from males caring for eggs and newly experienced males caused the female to alter her choice to a previously undesired male. However, conditioned water from males, which had reproduced but were isolated for 2 weeks, did not have the same effect on pairing behaviour. This indicates that the smell of experience is short lived.     

小学教师职业倦怠维度发展顺序探究——来自结构方程模型和交叉滞后网络分析模型的证据

教师职业倦怠的情感衰竭、去人性化和个人成就感降低3个维度相对独立但也存在相互影响, 对其发展关系进行研究, 有助于深入理解职业倦怠的发展过程, 尽早识别倦怠症状。本研究对3837名小学教师进行追踪测试, 测试间隔为3年, 采用结构方程模型和交叉滞后网络分析模型进行分析, 结果发现小学教师职业倦怠维度最优发展模型为“T1的情感衰竭和个人成就感降低分别预测T2的情感衰竭和个人成就感降低, T1的去人性化预测T2的去人性化和个人成就感降低”, 且最优发展模型具有性别间的一致性和教龄段之间的一致性。这一结果支持并强调了去人性化在小学教师职业倦怠发展中的重要作用, 对识别教师职业倦怠早期症状并采取相应措施有效阻断教师职业倦怠的进一步发展具有一定的理论和现实意义。
