自传记忆事件聚集现象中的组织和提取特点

事件聚集是在事件水平上组织自传记忆的结构,是一种反映自传记忆组织的提取现象.在利用矫正后的事件追随任务对62名成人进行测试后发现:①事件之间各种组织信息并不是分离的,而是以整合的方式来组织事件聚集结构,这些信息不仅包含客体的信息,更包含主观的感受.②自我在自传记忆组织中的作用是强化事件聚集本身所具有的联系.③自传记忆的提取中首先要满足当前自我的要求;进行直接提取失败后,被试根据自传记忆的层级关系进行生成搜索;生成提取策略也失败后,个体则会根据事件线索中任何可以利用的细节来完成回忆任务.     

异维A酸组和维胺酯组治疗痤疮的比较

为了比较分析异维A酸组和维胺酯组治疗痤疮的临床疗效、费用和不良反应,于服药前后观察疗效、不良反应和相关费用。结果显示,异维A酸组治疗痤疮起效快。在治疗中度痤疮,两组总体疗效、医疗费用相当,但维胺酯组不良反应较轻。而在治疗重度痤疮方面,异维A酸组临床疗效较维胺酯组高,且医疗成本较低。     

Activating event knowledge

An increasing number of results in sentence and discourse processing demonstrate that comprehension relies on rich pragmatic knowledge about real-world events, and that incoming words incrementally activate such knowledge. If so, then even outside of any larger context, nouns should activate knowledge of the generalized events that they denote or typically play a role in. We used short stimulus onset asynchrony priming to demonstrate that (1) event nouns prime people (sale-shopper) and objects (trip-luggage) commonly found at those events; (2) location nouns prime people/animals (hospital-doctor) and objects (barn-hay) commonly found at those locations; and (3) instrument nouns prime things on which those instruments are commonly used (key-door), but not the types of people who tend to use them (hose-gardener). The priming effects are not due to normative word association. On our account, facilitation results from event knowledge relating primes and targets. This has much in common with computational models like LSA or BEAGLE in which one word primes another if they frequently occur in similar contexts. LSA predicts priming for all six experiments, whereas BEAGLE correctly predicted that priming should not occur for the instrument-people relation but should occur for the other five. We conclude that event-based relations are encoded in semantic memory and computed as part of word meaning, and have a strong influence on language comprehension.     

An empirical and computational investigation of perceiving and remembering event temporal relations

Events have beginnings, ends, and often overlap in time. A major question is how perceivers come to parse a stream of multimodal information into meaningful units and how different event boundaries may vary event processing. This work investigates the roles of these three types of event boundaries in constructing event temporal relations. Predictions were made based on how people would err according to the beginning state, end state, and overlap heuristic hypotheses. Participants viewed animated events that include all the logical possibilities of event temporal relations, and then made temporal relation judgments. The results showed that people make use of the overlap between events and take into account the ends and beginnings, but they weight ends more than beginnings. Neural network simulations showed a self-organized distinction when learning temporal relations between events with overlap versus those without.     

Prospective coding in event representation

A perceived event such as a visual stimulus in the external world and a to-be-produced event such as an intentional action are subserved by event representations. Event representations do not only contain information about present states but also about past and future states. Here we focus on the role of representing future states in event perception and generation (i.e., prospective coding). Relevant theoretical issues and paradigms are discussed. We suggest that the predictive power of the motor system may be exploited for prospective coding not only in producing but also in perceiving events. Predicting is more advantageous than simply reacting. Perceptual prediction allows us to select appropriate responses ahead of the realization of an (anticipated) event and therefore, it is indispensable to flexibly and timely adapt to new situations and thus, successfully interact with our physical and social environment.     

以信息增益模式探讨在高维数据上的多类别证型分类

在慢性胃炎研究上决策树归纳法之使用已渐增加,以决策树归纳法同时表示信息增益以区别胃炎症状对证型分类之贡献,能更正确地区别慢性胃炎。而信息增益已广泛地用于评估两分分类,仅有很少报导有关多类别慢性胃炎分类,它需要探索多类别慢性胃炎分类之信息增益。本研究提出基于名目及次序样本类结果的决策树归纳法所做的多类别慢性胃炎分类,例如,不同慢性胃炎次型的症状样本,评估是以决策树归纳法与Friedman-Goldszmid,HGC,Cheng判别法之正确率作比较。显示平均正确率64.9%优于前三者且提高1.55%。     

The Wind Chilled the Spectators, but the Wine Just Chilled: Sense, Structure, and Sentence Comprehension

Anticipation plays a role in language comprehension. In this article, we explore the extent to which verb sense influences expectations about upcoming structure. We focus on change of state verbs like shatter , which have different senses that are expressed in either transitive or intransitive structures, depending on the sense that is used. In two experiments we influence the interpretation of verb sense by manipulating the thematic fit of the grammatical subject as cause or affected entity for the verb, and test whether readers' expectations for a transitive or intransitive structure change as a result. This sense-biasing context influenced reading times in the postverbal regions. Reading times for transitive sentences were faster following good-cause than good-theme subjects, but the opposite pattern was found for intransitive sentences. We conclude that readers use sense-contingent subcategorization preferences during on-line comprehension.     

Event structure as a basis of semantic processing of familiar metaphors

In this paper I propose a model of metaphor interpretation that would account for the possibility that semantic processing of familiar metaphors no longer go through the sequential steps of alignment and projection, but may rather be established upon schematic semantic units allowing faster processing. The proposition is grounded on the notion that metaphors are formed based on peoples’ perception of what is typically associated with entities. It is suggested that in its most abstract form, these associations are essentially events, analyzed in terms of event structure.     

基于心理痛苦理论与决策树的中学生心理危机分类模型

中学生心理危机分类模型属于复杂数据模型，本文采用分类树算法探究家庭、校园、同伴和个体因素在中学生心理危机分类中的相对重要性差异，尤其是心理痛苦三因素对致死性危机的独特作用。结果显示：（1）中学生自杀危机和非致死性危机分类树的分类效果良好，自伤危机分类树的分类效果欠佳；（2）中学生自杀危机中，痛苦逃避最为重要，痛苦唤醒次之，之后为痛苦体验和学校满意度；（3）中学生自伤危机中，同伴问题行为最为重要，之后为父母陪伴和家庭监督；（4）中学生非致死性危机中，歧视知觉最为重要，之后为痛苦唤醒和同伴支持。提示中学生不同心理危机的促发机制存在差异，心理痛苦三因素模型在自杀分类模型中作用显著，但并非自伤危机和非致死性危机的关键变量。     

Assessment of Major Life Events for Hong Kong Adolescents: The Chinese Adolescent Life Event Scale

Previous Chinese research on adolescent life stress adopted life event scales that were directly translated from Western measures. To address the methodological and cultural issues overlooked by the import approach, the present research aimed at constructing a life event scale for Hong Kong adolescents. Study 1 was conducted to congregate items for the Chinese Adolescent Life Event Scale (CALES). The CALES contains 44 items derived from 618 Hong Kong adolescents. Study 2 revealed adequate test–retest reliability and criterion-related validity for the CALES. Moreover, the CALES yielded stronger relationships with depression than did the translated life event measures. Results suggest that the CALES is appropriate for assessing life events for Hong Kong adolescents. Both unique features of the CALES and life events found only in the translated measures are examined. Implications for Chinese research on life stress are discussed.
