The role of executive function in reading comprehension among beginning readers

Empirical evidence supports the importance of executive function (EF) in reading, but the underlying mechanism through which EF contributes to the reading process is unclear. The present study examined the direct and indirect effects of EF on reading comprehension through the indirect pathway of language and cognitive skills (i.e., syntactic awareness and text-connecting inferencing) among the beginning readers. The sample included one hundred and sixty-five 2^nd and 3^rd grade students. The participants were tested on working memory (visuospatial working memory and verbal working memory) and inhibition (prepotent response inhibition and cognitive inhibition), and their syntactic awareness, inference-making, and reading comprehension. The unitary EF construct was obtained by means of confirmatory factor analysis based on the structure of EF in middle childhood suggested in developmental studies. Structural equation modelling was used to examine the direct and indirect effects of EF on the reading outcome. The findings indicated that EF has a direct effect on reading comprehension among the beginning readers. The indirect pathway showed that EF supports the ability to evaluate on grammatical structure of sentences (i.e., syntactic awareness) during reading. However, the indirect effect of EF on reading via inference-making ability is insignificant. The findings highlight the contributions of EF to reading and provide empirical evidence to the hypothetical relation between EF and language skills suggested in DIER (Kim, 2020, Resarch Quarterly, 50, 459). It further extends our knowledge on the roles of EF in the reading process among the beginning readers. Future research directions are implicated as well.     

The role of age and perceptual symbols in language comprehension

Older and younger participants read sentences about objects and were then shown a picture of an object that either matched or mismatched the implied shape of the object in the sentence. Participants' response times were recorded when they judged whether the object had been mentioned in the sentence. Responses were faster in the shape-matching condition for all participants, but the mismatch effect was stronger for older than for younger adults, even when the larger variability of the older group's response times was controlled for. These results suggest that older adults may construct stronger situation models than younger adults.     

Emotion simulation during language comprehension

We report a novel finding on the relation of emotion and language. Covert manipulation of emotional facial posture interacts with sentence valence when measuring the amount of time to judge valence (Experiment 1) and sensibility (Experiment 2) of the sentence. In each case, an emotion-sentence compatibility effect is found: Judgment times are faster when facial posture and sentence valence match than when they mismatch. We interpret the finding using a simulation account; that is, emotional systems contribute to language comprehension much as they do in social interaction. Because the effect was not observed on a lexical decision task using emotion-laden words (Experiment 3), we suggest that the emotion simulation affects comprehension processes beyond initial lexical access.

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 role of mutual knowledge in the development of perspective taking

Analysis of research on the development of perspective taking and social cognition leads to a new theoretical synthesis centered around the concept of mutual knowledge. Mutual knowledge is shared, and assumed by the knower to be shared, with other people. Attention to individual mental states, the usual subject matter of social-cognitive research, is necessary only in problematic interactions such as misunderstandings, deceptions, or other strategic interactions in which the ordinary assumption of mutual knowledge must be put aside. The present formulation is able to account for the structural transformations in social-cognitive development while retaining the processing capacity assumptions of the information-processing approaches.     

The role of structure in coreference assignment during sentence comprehension

This paper examines the role of symtactic constraints on the reactivation and assignment of antecedents to explicit and implicit anaphoric elements during sentence comprehension. Evidence from on-line studies examining the time course of coreference processing supports the view that reactivation of potential antecedents is restricted by grammatical constraints when they are available. When structural information cannot serve to constrain antecedent selection, then pragmatic information may play a role, but only at a later point in processing.     

Pupillometry reveals processing load during spoken language comprehension

This study investigated processing effort by measuring peoples’ pupil diameter as they listened to sentences containing a temporary syntactic ambiguity. In the first experiment, we manipulated prosody. The results showed that when prosodic structure conflicted with syntactic structure, pupil diameter reliably increased. In the second experiment, we manipulated both prosody and visual context. The results showed that when visual context was consistent with the correct interpretation, prosody had very little effect on processing effort. However, when visual context was inconsistent with the correct interpretation, prosody had a large effect on processing effort. The interaction between visual context and prosody shows that visual context has an effect on online processing and that it can modulate the influence of linguistic sources of information, such as prosody. Pupillometry is a sensitive measure of processing effort during spoken language comprehension.     

Eye-fixation patterns during reading confirm theories of language comprehension

Eye-movement patterns during reading are consistent with proposition-by-proposition models of speech comprehension. (1) Fixation times are least affected by word length at ends of clauses: this confirms the theory based on the study of speech comprehension that, at such points, attention is directed inward to text integration. (2) Fixation time for words at the end of clauses is longer for canonical sequences which conform to the pattern, “N-V-N = actor-action-object”; this confirms the view that complete semantic integration of such sequences is routinely delayed until their completion. A two-variable model based on principles of exhaustive visual search and speech comprehension accounts for 80% of the fixation durations in a sample paragraph from Just and Carpenter (1980) and Thibodeou, Just ond Carpenter (1982). This comprehension-based model compares favorably with their models constructed within a production-system framework. This result clarifies the relationship between reading and listening.     

On-line processing of social stereotypes during spoken language comprehension

Four experiments investigated stereotype processing during the on-line comprehension of spoken sentences. Participants listened to a critical prime (terrorist) embedded in a sentence and then made lexical decisions to visually presented standard-related (bomb) or stereotype-related targets (Arab) or unrelated controls for both conditions. For Experiments 1A and 1B, the preceding context provided no contextual information about the critical prime. Targets were presented at prime offset (Experiment 1A) or 300 ms after prime offset (Experiment 1B). In Experiments 2A and 2B, the preceding context was biased towards the stereotype meaning of the critical prime. Visual targets were presented at prime offset (Experiment 2A) or 300 ms after prime offset (Experiment 2B). Experiment 1A revealed a priming effect, but only for the standard meaning (i.e., bomb) of the critical prime. This effect was further replicated in Experiments 1B, 2A and 2B; however, for these experiments, unlike Experiment 1A, the results revealed lexical inhibition for the stereotype meaning of the critical prime. That is, lexical decisions to the stereotype-related targets were actually slower than the stereotype-unrelated controls. The results are discussed in terms of current social cognitive models of stereotype processing.     

The handedness of imagined bodies in action and the role of perspective taking

Past research at the nexus of motor control and perception investigated the role of perspective taking in many behavioral and neuroimaging studies. Some investigators addressed the issue of one's own vs. others' action imagination, but the possible effects of a front or a back view in imagining others' actions have so far been neglected. We report two 'single trial' experiments in which a total of 640 participants were asked to imagine a person performing a manual action - either in a front or in a back view - and then to indicate the hand used by the imagined person during movement execution. In such a task, we assume the existence of two distinct biases: a perceptual-mnemonic bias due to subjects' visual experience of others' actions, encouraging them to imagine right-handed movements, and a motor bias due to subjects' experience of self-made actions, encouraging them to imagine movements performed with the same hand as their dominant hand. We hypothesized that a greater involvement of motor representations in the back view compared to the front view could result in an increased correspondence between one's own manual preference and the hand used by the imagined agent in the former condition. The results of both experiments were consistent with this hypothesis, suggesting that while imagining others' actions we employ motor simulations in different degrees according to the perspective adopted.     

The role of perspective taking and emotions in punishing identified and unidentified wrongdoers

We present two studies examining the effect of identifiability on willingness to punish, emphasising that identifiability of the wrongdoer may increase or decrease willingness to punish depending on the punisher's perspective. When taking the wrongdoer's perspective, identifiability increases pity and decreases anger towards the wrongdoer, leading to a lighter punishment. On the other hand, when adopting the injured perspective, identifiability decreases pity and increases anger, resulting in a severe punishment. We show that while deliberation and rational factors affect the decision regardless of identification, the role of emotions in the decision is greater in the identified condition. Possible implications for public and educational policy are discussed.

How does parallel language activation affect switch costs during trilingual language comprehension?

ABSTRACT

Declerck, M., Koch, I., Duñabeitia, J., Grainger, J., & Denise, N. [(2019). What absent switch costs and mixing costs during bilingual language comprehension can tell us about language control? Journal of Experimental Psychology Human Perception & Performance.] assumed that the absence of switch costs in bilingual language comprehension may be due to little degree of parallel language activation while substantial degree of it may lead to switch costs. This study tested this assumption by examining the switch costs during Russian-English-Chinese trilinguals’ performing lexical decision tasks in language pairs of L1–L2 in Experiment 1a, L1–L3 in Experiment 1b and L2–L3 in Experiment 1c. We found switch costs in L2 in Experiment 1a and switch costs in both L1 and L3 in Experiment 1b, but no switch costs in both L2 and L3 in Experiment 1c. These results generally provided evidence for the account.     

语言理解中的预设加工

预设是指以交际双方的共同背景(共享的知识或信念)为前提的、听话者根据特定语言标记(触发标记)及其限定的对象(计算内容)而推理出的非外显意义。例如,“张明又触发标记发表了论文计算内容”引发了“张明之前发表过论文”的预设推论。理解者依赖触发标记通达交际双方的共同背景,并在计算内容上生成完整的预设;随后,理解者连接生成的预设和共同背景,更新两者之间的关系。触发标记范畴、共同背景与预设的关联度、共同背景类型,以及理解者的参与动机会影响不同阶段的预设加工。未来研究可以从三个角度进一步探讨预设加工的认知基础：(1)采用计算建模的方法,量化交际互动中听话者理解预设的过程(如观点采择);(2)采用脑成像技术,揭示预设加工过程的神经基础;(3)以特殊人群为研究对象,检验和修正预设加工的认知模型。     

Taking perspective in conversation: the role of mutual knowledge in comprehension

When people interpret language, they can reduce the ambiguity of linguistic expressions by using information about perspective: the speaker's, their own, or a shared perspective. In order to investigate the mental processes that underlie such perspective taking, we tracked people's eye movements while they were following instructions to manipulate objects. The eye fixation data in two experiments demonstrate that people do not restrict the search for referents to mutually known objects. Eye movements indicated that addressees considered objects as potential referents even when the speaker could not see those objects, requiring addressees to use mutual knowledge to correct their interpretation. Thus, people occasionally use an egocentric heuristic when they comprehend. We argue that this egocentric heuristic is successful in reducing ambiguity, though it could lead to a systematic error.     

Processing motion implied in language: eye-movement differences during aspect comprehension

Previous research on language comprehension has used the eyes as a window into processing. However, these methods are entirely reliant upon using visual or orthographic stimuli that map onto the linguistic stimuli being used. The potential danger of this method is that the pictures used may not perfectly match the internal aspects of language processing. Thus, a method was developed in which participants listened to stories while wearing a head-mounted eyetracker. Preliminary results demonstrate that this method is uniquely suited to measure responses to stimuli in the absence of visual stimulation.     

Time in language: event duration in language comprehension

This work investigates how we process and represent event duration in on-line language comprehension. Specifically, it examines how events of different duration are processed and what type of knowledge underlies their representations. Studies 1–4 examined verbs and phrases in different contexts. They showed that durative events took longer to process than non-durative events and that the duration attributed to the stimulus events correlated with on-line processing times. Studies 5 and 6 indicated that durative events occur in semantically more diverse contexts and elicit semantically more diverse associations than non-durative events. Semantic and contextual diversity also correlated with attributed durations and processing times. Results indicate that (a) event-specific durations are computed on-line from multiple unfolding cues, (b) processing cost and duration representations emerge from semantic and contextual diversity reflecting our experience, and (c) key components of duration representations may be situation-specific knowledge of causal and contingency relations between events.
