分散空间注意条件下客体特征一致性对视觉特征错觉性结合的影响

本研究通过设置对空间注意资源的分配实施强行操作的情形下,探讨了主、次作业客体形状一致性和次作业客体间距对乏空间注意区次作业客体颜色、形状特征的检测及对特征错觉性结合的影响。实验结果表明：（１）分散空间注意使次作业区域注意减弱,对客体及其颜色和形状特征的识别均产生明显影响．而且对形状的影响又大于颜色;（２）特征错觉性结合率,主、次作业客体形状一致时比客体形状不一致时明显增大;（３）次作业客体间距对特征错觉性结合率无明显影响,但客体形状一致性和客体间距之间存在明显交互作用．

Walking through doorways causes forgetting: environmental effects

Previous work has shown a decline in memory for objects carried through a doorway versus across a room. The aim of the current study is to extend this work to understand how variations in perceptual experience during these event shifts influence this finding. First a change in procedure to reduce memory load to a single item was assessed. Next we explored whether performance is influenced by spatial distance versus spatial categories, the ability to perceptually preview the next location, and changes in the colour and texture of the walls. The location updating effect was consistently observed for all manipulations, suggesting that such event transformations have a robust influence on human memory. This suggests that event cognition is driven more by the use of perceptual information to infer or impose a categorical shift from one event to another rather than by the nature of perceptual information available at the time.     

Integration of spatial information across vision and language

Three experiments investigated whether spatial information acquired from vision and language is maintained in distinct spatial representations on the basis of the input modality. Participants studied a visual and a verbal layout of objects at different times from either the same (Experiments 1 and 2) or different learning perspectives (Experiment 3) and then carried out a series of pointing judgments involving objects from the same or different layouts. Results from Experiments 1 and 2 indicated that participants pointed equally fast on within- and between-layout trials; coupled with verbal reports from participants, this result suggests that they integrated all locations in a single spatial representation during encoding. However, when learning took place from different perspectives in Experiment 3, participants were faster to respond to within- than between-layout trials and indicated that they kept separate representations during learning. Results are compared to those from similar studies that involved layouts learned from perception only.     

3~5岁儿童理解和使用空间表征的特点

以96名3~5儿童为被试,采用自编的儿童空间表征实验任务,在语言表征、模型表征和图画表征三种空间表征形式上,考察了儿童理解和使用空间表征的发展特点。结果表明:(1)总体上,3~5岁儿童理解空间表征的发展水平均显著高于使用空间表征的发展水平。(2)3~5岁儿童理解和使用空间表征的发展表现出显著的年龄效应。(3)从不同的空间表证形式来看,3岁儿童理解语言表征的能力与理解模型表征的能力之间差异显著,4岁儿童使用语言表征的能力与使用模型表征的能力之间的差异、使用语言表征的能力与使用图画表征的能力之间的差异、以及使用模型表征的能力与使用图画表征的能力之间的差异都显著,其余形式的空间表征理解之间的差异或空间表征使用之间的差异在各年龄段中均不显著。     

相对熟悉度和同音线索在谐音型歇后语理解中的作用

谐音型歇后语是汉语特殊的语汇表达形式, 对其加工常常需要通达后一语节的同音线索来完成语音、语义隐喻映射。本研究通过2个实验探讨相对熟悉度和同音线索类型对谐音型歇后语加工的作用。实验1结果表明, 在高熟悉度条件下, 被试对语汇的加工策略取决于歇后语的同音线索类型。当后一语节为同音字时, 加工较为快速; 当后一语节为谐音字时, 通达歇后语隐喻意义的路径受阻。对熟悉度较高的谐音型歇后语进行加工, 语义通达表现出预存性; 在缺乏同音线索的条件下, 语料加工时间较长, 反应准确率较低, 支持概念隐喻模型和概念合成假说。而对熟悉度较低的歇后语进行加工, 被试更倾向于采用即时(on-line)策略, 支持概念合成理论和基于心理模型的语用推理假说。实验2结果表明, 呈现“错误同音”线索对歇后语的加工形成干扰, 不支持概念合成理论和基于心理模型的语用推理理论。总的结果表明, 相对熟悉度和同音线索类型影响谐音型歇后语的通达, 谐音歇后语加工需要同时激活语音和语义两条通道。     

Picture this! Effects of photographs,diagrams, animations,and sketching on learning and beliefs about learning from a geoscience text

Many studies have demonstrated that illustrating expository science texts with images that are interesting, but irrelevant for understanding the causal relations underlying scientific phenomena, can cause seduction effects, which can reduce understanding from text. The term “seduction effects” refers to the influence that images are thought to have on readers, seducing them away from deeply processing important information. The present study explores whether images relevant for instructional goals may also show some seduction effects. In this study, the presence of photographic images negatively impacted understanding compared with the presence of relevant animations or instructing students to sketch a drawing during reading. However, the results showed that both photographic images and relevant animations could lead to illusions of understanding, whereas sketching did not. The results suggest that even images that are relevant for instructional goals may sometimes result in seduction effects that deceive readers when judging their own understanding.     

具身认知视角下的道德隐喻表征

道德隐喻已成为道德心理学研究的热点问题,随着具身认知相关理论的兴起,道德隐喻的具身研究逐渐展开。目前,具身道德隐喻的维度主要包括空间、温度、洁净、颜色、明暗、触觉、味觉、嗅觉等。具身道德隐喻的相关理论解释主要包括概念隐喻理论、具身认知理论、知觉符号理论和架构理论。今后的具身道德隐喻应更多的探讨跨文化的差异性,丰富道德隐喻具身维度的内容以及各维度之间的相关性,同时要引入道德隐喻的影响机制分析。     

Improving visual spatial working memory in younger and older adults: effects of cross-modal cues

Spatially informative auditory and vibrotactile (cross-modal) cues can facilitate attention but little is known about how similar cues influence visual spatial working memory (WM) across the adult lifespan. We investigated the effects of cues (spatially informative or alerting pre-cues vs. no cues), cue modality (auditory vs. vibrotactile vs. visual), memory array size (four vs. six items), and maintenance delay (900 vs. 1800 ms) on visual spatial location WM recognition accuracy in younger adults (YA) and older adults (OA). We observed a significant interaction between spatially informative pre-cue type, array size, and delay. OA and YA benefitted equally from spatially informative pre-cues, suggesting that attentional orienting prior to WM encoding, regardless of cue modality, is preserved with age. Contrary to predictions, alerting pre-cues generally impaired performance in both age groups, suggesting that maintaining a vigilant state of arousal by facilitating the alerting attention system does not help visual spatial location WM.     

Exploring the depths of the rainforest: a metaphor for teaching critical reflection

Many social welfare and social work students struggle to demonstrate competence in the complex process of critical reflection through to the stage of transformed thinking and action. Examples of how students learn critical reflection as an interpretive experience are scarce. This paper presents, as a case study, the process one of the authors experienced while critically reflecting on teaching critical reflection. The paper explores how this approach unlocked disturbing insights into how personally held values, views and knowledge influenced her performance relating to teaching critical reflection. Experiencing what she asks of her students raised questions regarding the duty of care that social welfare and social work educators have to ensure their students engage in critical, and transformative, self-discovery in safe and supportive ways. We propose that in the early stages of social welfare and social work degrees, rather than assessing students’ critical reflection of an event, educators examine students’ capacity to learn critical reflection in a different way. Drawing on critical hermeneutics, and a theory of visual thinking, the paper outlines the cognitive map of a process of critical reflection on teaching critical reflection. We present this as a metaphor of walking through a rainforest.
