This article explores young infants' ability to learn new words in situations providing tightly controlled social and salience cues to their reference. Four experiments investigated whether, given two potential referents, 15-month-olds would attach novel labels to (a) an image toward which a digital recording of a face turned and gazed, (b) a moving image versus a stationary image, (c) a moving image toward which the face gazed, and (d) a gazed-on image versus a moving image. Infants successfully used the recorded gaze cue to form new word-referent associations and also showed learning in the salience condition. However, their behavior in the salience condition and in the experiments that followed suggests that, rather than basing their judgments of the words' reference on the mere presence or absence of the referent's motion, infants were strongly biased to attend to the consistency with which potential referents moved when a word was heard. 相似文献

Studies monitoring eye-movements in scenes containing entities have provided robust evidence for incremental reference resolution processes. This paper addresses the less studied question of whether depicted event scenes can affect processes of incremental thematic role-assignment. In Experiments 1 and 2, participants inspected agent-action-patient events while listening to German verb-second sentences with initial structural and role ambiguity. The experiments investigated the time course with which listeners could resolve this ambiguity by relating the verb to the depicted events. Such verb-mediated visual event information allowed early disambiguation on-line, as evidenced by anticipatory eye-movements to the appropriate agent/patient role filler. We replicated this finding while investigating the effects of intonation. Experiment 3 demonstrated that when the verb was sentence-final and thus did not establish early reference to the depicted events, linguistic cues alone enabled disambiguation before people encountered the verb. Our results reveal the on-line influence of depicted events on incremental thematic role-assignment and disambiguation of local structural and role ambiguity. In consequence, our findings require a notion of reference that includes actions and events in addition to entities (e.g. Semantics and Cognition, 1983), and argue for a theory of on-line sentence comprehension that exploits a rich inventory of semantic categories. 相似文献

The purpose of this note is twofold: (a) to present the formula for the item information function (IIF) in any direction for the Multidimensional 3-Parameter Logistic (M3-PL) model and (b) to give the equation for the location of maximum item information (θmax) in the direction of the item discrimination vector. Several corollaries are given. Implications for future research are discussed.This research was supported in part by an Educational Testing Service (ETS) Harold T. Gulliksen Psychometric Research Fellowship to the author.This revised article was published online in August 2005 with the PDF paginated correctly. 相似文献

采用混合实验设计,以含有空间信息的语篇为实验材料,选取不同视空间工作记忆广度的大学生作为被试,利用新的实验范式分离了空间情境模型的建立过程和更新过程,对这两个过程在不同时间模式下的加工特点进行分析,考察了空间情境模型建立和更新的影响因素。研究发现:(1)视空间工作记忆广度影响空间情境模型的建立,但不影响空间情境模型的更新。(2)时间模式既影响空间情境模型的建立又影响空间情境模型的更新。(3)方位对空间情境模型的建立有显著影响,对空间模型的更新没有显著影响。在空间情境模型的建立和更新过程中,前后判断的准确性不易受限时的影响,而左右判断的准确性则易受到限时的影响而显著降低,前后方位效应具有稳定性和优势性 相似文献

Rudolf Otto’s work, The Idea of the Holy [Das Heilige], is both new and old: it puts the idea of the holy or numinous into the mainstream of Christian discourse, but does this in a way that is deeply embedded in Otto’s heritage. The psychoanalytic lens puts a spotlight on engaging with the numinous from the complete experience of being human. In terms of spiritual direction, that enables a deeply incarnational approach, which is also indebted to apophatic forms of spirituality that can easily be under-valued. 相似文献

A substantial amount of recent work in natural language generation has focused on the generation of 'one-shot' referring expressions whose only aim is to identify a target referent. Dale and Reiter's Incremental Algorithm (IA) is often thought to be the best algorithm for maximizing the similarity to referring expressions produced by people. We test this hypothesis by eliciting referring expressions from human subjects and computing the similarity between the expressions elicited and the ones generated by algorithms. It turns out that the success of the IA depends substantially on the 'preference order' (PO) employed by the IA, particularly in complex domains. While some POs cause the IA to produce referring expressions that are very similar to expressions produced by human subjects, others cause the IA to perform worse than its main competitors; moreover, it turns out to be difficult to predict the success of a PO on the basis of existing psycholinguistic findings or frequencies in corpora. We also examine the computational complexity of the algorithms in question and argue that there are no compelling reasons for preferring the IA over some of its main competitors on these grounds. We conclude that future research on the generation of referring expressions should explore alternatives to the IA, focusing on algorithms, inspired by the Greedy Algorithm, which do not work with a fixed PO. 相似文献

采用线段平分任务,以无文字线索作为基线条件,考察文字线索的浏览方向、空间位置和移动光标对具有两种不同方向阅读经验的熟练双语者伪忽视的影响。结果发现,无文字线索条件下,光标从左往右方向移动时被试的判断偏向于线段中点的右侧,而从右往左移动时,偏向于线段中点的左侧。在有文字线索条件下发现,文字线索的浏览方向和空间位置的交互作用显著,简单效应检验显示文字线索的浏览方向和空间位置一致时伪忽视明显,不一致时伪忽视消失。结果表明,文字线索浏览方向、空间位置与移动光标能够影响伪忽视。伪忽视的存在和消失,不仅与眼球运动有关,还有与大脑两半球的激活水平有关。研究结果支持了视觉扫描假设和激活朝向假设。 相似文献
