编码方式与指拼特征在聋生手语词加工中的作用研究

本研究探讨了聋生在加工手语词过程中不同编码方式和指拼特征的影响。实验1采用指拼类手语词和手势类手语词考察了指拼有无对手语词编码方式的影响。实验2则采用不同特征的指拼类手语词,深入考察指拼位置、指拼形式对手语词编码方式的影响。结果表明,聋生较语音编码更擅长使用指拼编码加工手语词;指拼与手势的加工存在显著差异,指拼在聋生手语词加工中起到了促进作用;指拼位置与指拼形式共同作用于手语词的加工过程。     

Happy thoughts: Enhancing well-being in the classroom with a positive events diary

Positive psychology interventions (PPIs) are effective in increasing well-being across the population. Whilst educators are recognising the importance of well-being in the classroom and of its long-term impact on life trajectory, the transformative potential of PPIs in educational settings is yet to be fully realised. This study investigates, for the first time, the effects of a PPI in school children by means of a daily dairy. Self-report questionnaires were used to measure well-being in school children aged 8–11 years. Across two studies, children kept a positive events diary, recording three experiences every day for a week. The intervention led to an increase in happiness and a decrease in depressive symptoms immediately following the intervention and at a three-month follow-up. Children who had unhappier baseline scores benefitted more from the intervention. This study demonstrates significant scope, in school settings, for targeted light-touch interventions to promote well-being in those with the greatest need.     

The perception of (naked only) bodies and faceless heads relies on holistic processing: Evidence from the inversion effect

Faces and bodies are more difficult to perceive when presented inverted than when presented upright (i.e., stimulus inversion effect), an effect that has been attributed to the disruption of holistic processing. The features that can trigger holistic processing in faces and bodies, however, still remain elusive. In this study, using a sequential matching task, we tested whether stimulus inversion affects various categories of visual stimuli: faces, faceless heads, faceless heads in body context, headless bodies naked, whole bodies naked, headless bodies clothed, and whole bodies clothed. Both accuracy and inversion efficiency score results show inversion effects for all categories but for clothed bodies (with and without heads). In addition, the magnitude of the inversion effect for face, naked body, and faceless heads was similar. Our findings demonstrate that the perception of faces, faceless heads, and naked bodies relies on holistic processing. Clothed bodies (with and without heads), on the other side, may trigger clothes-sensitive rather than body-sensitive perceptual mechanisms.     

Toward a New Paradigm of Health and Human Potential

In today's highly dynamic and changing industries there are an incredible array of things converging, all of which are signalling a significant need for a new paradigm in health and medicine. Scientific revolutions have brought forward new forms of knowledge, which fundamentally oppose the premises on which the majority of our traditional medical institutions are based. Through my CIRR framework (Critique, Insight, Re-Define, Re-Structure) I will bring forward the key elements and principles of what this paradigm shift is and what would be involved in bringing it into fruition. There are 3 key elements of a paradigm shift which I will review through the CIRR framework these are a) structural and systemic elements b) dynamics of social constituents and pathologies and c) shifts in thinking that have given rise to new forms of knowledge that enable new forms of research and practice. I will demonstrate that the key elements involved in a genuine paradigm shift are here, however it's up to us to bring it into fruition. I hope to inspire both researchers and practitioners towards this new paradigm in health and human potential.     

Looking forward: the effects of photographs on the qualities of future thinking

Future episodic thinking relies on the reconstruction of remembered experiences. Photographs provide one means of remembering, acting as a “cognitive springboard” for generating related memory qualities. We wondered whether photographs would also invite embellishment of future thought qualities, particularly in the presence (or absence) of associated memories. In two studies participants generated future events in familiar (associated memories) and novel (no associated memories) locations. Half of the participants viewed scene location photographs during event generation. All participants then imagined the events for one minute and completed a self-report measure of content qualities. Results of the current set of studies suggested that for novel locations, no differences in qualities emerged; however, for familiar locations, photographs did not enhance qualities and, in some cases, actually constrained perceptual (Experiments 1 and 2) and sensory (Experiment 1) detail ratings of future thoughts. Thus, photographs did not invite embellishment of future thought details.     

小学一年级阅读流畅性对二、三年级阅读理解的预测

采用追踪研究考察了124名小学一年级儿童的阅读流畅性对其二、三年级阅读理解的影响。结果发现,在控制了性别、家庭社会经济地位、推理能力、汉字识别、口语词汇及多种阅读相关认知技能之后,儿童一年级时的字词流畅性可以预期其二、三年级时的阅读理解水平,句子流畅性对二年级时阅读理解的变异有独特解释作用,但对三年级时阅读理解的变异没有显著的解释作用。相对于句子流畅性,字词流畅性在小学低年级阶段对阅读理解的贡献更大。     

老年人对情绪性事件的情景模拟:回忆过去与想象未来

研究采用自传体访谈技术,首次考察了老年人在对情绪性事件进行回忆和想象中生成的内部细节和外部细节数量,及其对回忆和想象内容的主观评估。结果发现:(1)无论是回忆还是想象任务,老年人都比年轻人提供了更少的内部细节和略多的外部细节;(2)与年轻人相似,老年人在想象未来积极事件时产生了更多的内部细节,表现出对积极信息的加工偏好;(3)老年人比年轻人更倾向于认为想象的事件与过去发生的事件相似度高,表明该群体在想象过程中更多地依赖了过去的记忆。该结果揭示了老年人对情绪性事件的回忆和想象特点,说明在回忆和想象过程中出现的与年龄有关的缺陷同样会体现在情绪性事件中,这很好地支持了建构性情景模拟假说。     

Anthropocentric by Default? Attribution of Familiar and Novel Properties to Living Things

Humans naturally and effortlessly use a set of cognitive tools to reason about biological entities and phenomena. Two such tools, essentialist thinking and teleological thinking, appear to be early developmental cognitive defaults, used extensively in childhood and under limited circumstances in adulthood, but prone to reemerge under time pressure or cognitive load. We examine the nature of another such tool: anthropocentric thinking. In four experiments, we examined patterns of property attribution to a wide range of living and non‐living objects, manipulating time pressure, response type, and property (either novel or familiar) in a total of 471 participants. Results showed no tendency toward increased similarity‐based attribution patterns indicative of anthropocentric thinking under time pressure. However, anthropocentric thinking was consistently observed for unfamiliar properties. These findings suggest that anthropocentric thinking is not a developmentally persistent cognitive default, but rather a cognitive strategy deliberately employed in situations of uncertainty.     

EMPIRICAL MINDFULNESS: TRADITIONAL CHINESE MEDICINE AND MENTAL HEALTH IN THE SCIENCE AND RELIGION DIALOGUE

As science and religion researchers begin to engage questions of mental health, mindfulness may prove to be a fruitful area of investigation. However, quantifying the physical effects of mindfulness on the brain is difficult because mindfulness deals with the problem of mental and physical interaction or, the mind/body problem. One system of understanding which may aid science and religion scholars in the pursuit of mindfulness is traditional Chinese medicine (TCM). Within TCM, heart Qi manages the body's present connection to time and space. If the “being in the moment” is disrupted, then the heart Qi is blocked and mental illness or various neurological disorders occur. Succinctly, within TCM, mindfulness is understood as a nonphysical phenomenon (Qi) which directly affects physical systems, resulting in empirical data. This is tracked and treated through the TCM understanding of Qi. The TCM view of Qi in mental health may therefore provide a helpful new paradigm to investigations concerning mindfulness and the human brain.
