语篇情绪理解及其认知神经机制

在心理语言学领域,情绪信息加工是语篇理解的重要方面,得到了广泛关注。目前的研究表明,读者在语篇阅读中可以在线地、自动地推测出语篇情绪信息,追踪情绪信息的变化,并对其进行更新。语篇理解相关的模型及一些事件相关电位(ERP)的实证研究表明语篇情绪理解至少包括两个重要的加工过程:一是对语篇情绪信息的实时监控,二是对当前情绪信息的评估与更新。相关的功能磁共振(f MRI)的研究表明语篇情绪理解除了需要经典的情绪加工网络,还需要多个脑区网络的参与,如,语篇理解网络、心理理论(To M)网络。未来研究还需更加深入地、更加细致地探讨语篇情绪理解的认知神经机制及其可能的影响因素,研究成果也可以为情感计算领域提供一定的借鉴。     

双语者语言转换中非目标语言的加工机制

语言转换是指双语者由所掌握的一种语言转换到另一种语言的现象, 这一现象近些年来引起了研究者的广泛关注。针对语言转换中双语者在从心理词典中顺利提取所需要的语言(称之为目标语言)时如何加工在当前任务中不使用的那种语言(称之为非目标语言), 研究者进行了大量研究。仔细分析这些研究, 可以看出这些研究主要围绕着3个核心问题: (1)语言转换中双语者使用目标语言时非目标语言是否激活; (2)若非目标语言激活, 这种激活发生在何种层面(概念层面还是词汇层面); (3)激活的非目标语言会对目标语言产生什么样的影响。以此为基础, 本文从语言产生转换和语言理解转换两大领域对相关研究进行了总结和梳理, 最后对未来的语言转换研究进行了展望。     

Understanding the glue of narrative structure: Children's on- and off-line inferences about characters’ goals

Because characters’ goals play a key role in the structure of narratives, the ability to make inferences about goals is essential to narrative comprehension. Despite their importance, no previous studies have examined the process by which children make these goal inferences. In the current study, we examined 6- and 8-year-old children's goal inference making processes through think-aloud protocols. We also examined the product of comprehension, the mental representation of text, through free recall and comprehension questions. The results revealed that children of both ages regularly made appropriate goal inferences while listening to narratives. In addition, the number of goal inferences predicted children's recall of the stories. Thus, children as young as 6 years old are sensitive to the vital role of characters’ goals in narrative structure, and they can engage in sophisticated cognitive processing while they listen to narratives to form coherent mental representations of them.     

The sound of motion in spoken language: visual information conveyed by acoustic properties of speech

Language is generally viewed as conveying information through symbols whose form is arbitrarily related to their meaning. This arbitrary relation is often assumed to also characterize the mental representations underlying language comprehension. We explore the idea that visuo-spatial information can be analogically conveyed through acoustic properties of speech and that such information is integrated into an analog perceptual representation as a natural part of comprehension. Listeners heard sentences describing objects, spoken at varying speaking rates. After each sentence, participants saw a picture of an object and judged whether it had been mentioned in the sentence. Participants were faster to recognize the object when motion implied by speaking rate matched the motion implied by the picture. Results suggest that visuo-spatial referential information can be analogically conveyed and represented.     

语音记忆和中央执行功能在不同年级儿童解码和语言理解中的作用

选取256名三~六年级儿童, 采用相关分析、结构方程模型等方法考察了语音记忆和中央执行功能在不同年级儿童的解码和语言理解中的作用。结果显示, 在低年级阶段, 语音记忆和刷新对解码存在显著预测作用, 转换和刷新对语言理解存在显著预测作用; 在高年级阶段, 只有刷新对解码保持着稳定的预测作用。这表明, 语音记忆和中央执行功能对儿童的解码和语言理解存在不同的影响, 并且这种影响会随着年级的增长发生变化。     

The impact of early maternal verbal scaffolding and child language abilities on later decoding and reading comprehension skills

This study examined, via structural equation modeling, early predictors of children's 8 year reading decoding and 10 year comprehension at later school age. Maternal verbal scaffolding indirectly influenced both decoding and comprehension, through its support of children's language abilities at 3 and 4 years of age. Additionally, there was a trend for a direct effect of 4 year child language on reading comprehension at 10 years. As maternal verbal scaffolding was assessed during every day routines, this suggests that rich language input in the broad social context of the home promotes language and, in turn, later reading skills. Given that maternal verbal scaffolding can be enhanced through interventions, these results have important educational implications.     

Moral chronicity and social information processing: Tests of a social cognitive approach to the moral personality

Following Higgins, King, and Mavin (1982) chronicity paradigm, we examined the effects of chronically accessed moral constructs for prototypic moral character using two different research paradigms, spontaneous trait inferencing and lexical decision. Study 1 presented target sentences in a deliberate or spontaneous processing condition. Recall was cued with either a dispositional or semantic cue. Moral chronics made more spontaneous trait inferences with dispositional cues than semantic cues. In Study 2, participants read stories about characters who did or did not help. Moral chronics were faster responding to probes reflecting negative evaluations of story characters who did not help when requested (e.g., “disloyal”). Findings support claims that the moral personality is usefully conceptualized in terms of the chronic accessibility of moral knowledge structures.     

Comprehension of simple quantifiers: empirical evaluation of a computational model

We examine the verification of simple quantifiers in natural language from a computational model perspective. We refer to previous neuropsychological investigations of the same problem and suggest extending their experimental setting. Moreover, we give some direct empirical evidence linking computational complexity predictions with cognitive reality. In the empirical study we compare time needed for understanding different types of quantifiers. We show that the computational distinction between quantifiers recognized by finite-automata and push-down automata is psychologically relevant. Our research improves upon, the hypotheses and explanatory power of recent neuroimaging studies as well as provides evidence for the claim that human linguistic abilities are constrained by computational complexity.     

The effect of prosody on conceptual combination

Research into people's comprehension of novel noun-noun phrases has long neglected the possible influences of prosody during meaning construction. At the same time, work in conceptual combination has disagreed about whether different classes of interpretation emerge from single or multiple processes; for example, whether people use distinct mechanisms when they interpret octopus apartment as property-based (e.g., an apartment with eight rooms) or relation-based (e.g., an apartment where an octopus lives). In two studies, we manipulate the prosodic emphasis patterns of novel noun-noun combinations (placing stress on the modifier noun, the head noun, or dual stress on both nouns) and ask participants to generate an interpretation for the novel phrase. Results show that people are faster to generate property-based interpretations when dual emphasis stresses both nouns equally, with prosody having little effect on the speed of relation-based interpretations. These findings highlight a role for prosody during meaning construction and underline important differences between relation- and property-based interpretations that are difficult to reconcile with unitary process views of conceptual combination.
