The role of assembled phonology in reading comprehension

The contribution of assembled phonology to phonological effects in reading comprehension was assessed. In Experiment 1, subjects judged the acceptability of sentences with regular, exception, and nonword homophone substitutions and orthographic controls. Significantly more errors occurred to sentences with regular-word homophones than to exception words, and error rates for nonword homophones were low and not significant. Experiment 2 showed that this was not due to differences in the sentence frames. In Experiment 3, the subjects judged as unacceptable those sentences containing an exception word that sounded correct when read according to spelling-to-sound rules. Significantly higher error rates occurred only for low-frequency exception words. Experiment 4 showed that task conditions affect semantic-categorization error rates for nonword homophones. These results indicate that both assembled and addressed phonology contribute to sentence and word comprehension, but the low error rate for nonwords suggests that an early lexical check may be applied.     

The role of lexical expertise in reading homophones

In Experiment 1, university students classified on lexical expertise on the basis of spelling plus nonword pronunciation accuracy made lexical decisions to homophones and control words. Homophones were accepted as words more slowly than control words, but lexical experts showed a smaller homophone cost than the less skilled group. In Experiment 2, similarly classified groups showed a large difference in their ability to detect homophones, with the low-expertise group showing a yes bias to high-frequency words, and having difficulty detecting homophones when mate-frequency was low. The results suggest superior use of orthography in the lexical experts and more reliance on semantic information in nonexperts, and support the importance of facility with orthography–phonology mappings in lexical expertise.     

Orthography and phonology in reading Japanese kanji words: Evidence from the semantic decision task with homophones

Correspondences between spelling and sound for Japanese kanji are complex and deep. The meaning of kanji words has generally been assumed to be accessed directly from orthography without phonological mediation. Experiment 1, however, replicated the findings of Van Orden (1987) that subjects made more false-positive errors on homophone foils than they did on nonhomophone controls in a semantic decision task, although they did so only when the foils were orthographically similar to the correct exemplars, which indicates both orthographic and phonological activations of meaning. Experiment 2 showed the same results when subjects were not required to pronounce the target words after semantic decisions, which indicates automatic phonological activation of kanji words. In Experiment 3, under pattern-masking conditions, this homophony effect was reduced but remained on errors, and the orthographic-similarity effect remained strong on both homophone and nonhomophone foils. These results suggest that both orthography and phonology play an important role in the comprehension of kanji words.     

The functions of phonology in the acquisition of reading: Lexical and sentence processing

It has been claimed (V. Coltheart, Laxon, Rickard, & Elton, 1988) that learners as well as skilled readers use phonology for multiple functions in reading-for-meaning tasks. This claim was examined using lexical decision and sentence evaluation tasks. It was found in the first experiment that the type of instruction learners had received determined whether there was prelexical use of phonology in responding to items out of sentence context. Type of instruction had no effect when the items were in context. In the second experiment, performances on a homophone sentence evaluation task and a homophone semantic decision task, which excluded sentence processing, were examined. The results suggest that phonology served the function of access to lexical meanings in addition to any function in postlexical sentence processing. The obtained relationships between relative frequencies of the presented and unpresented homophone mates and item accuracy on these tasks were inconsistent with exclusive use of “direct access” but consistent with access of lexical meanings via phonology and application of a “spelling-check” procedure when multiple homophonic meanings are activated.

The role of phonology in incidental vocabulary acquisition during silent reading

In two experiments, we investigated the role of phonology in learning new words incidentally during silent reading. Participants read sentence pairs containing novel or known words that varied in homophony (whether another word exists with an alternate spelling for the same pronunciation). In Experiment 1, we monitored readers' eye movements to investigate online processes involved in establishing meanings for novel words. In Experiment 2, participants completed cued recall and vocabulary recognition tasks after the reading session to assess the influence of phonological form on word learning. Eye movement results indicate that readers spent the most time reading novel homophones (e.g., skwosh) and surrounding context, indicating that phonological information is activated early during a reader's initial encounter with a new letter string. Retention measures suggest that readers were able to infer a meaning for each novel word type, despite the increased difficulty associated with reading novel words with familiar phonological forms, and that phonology aided the acquisition of orthography.     

Contextual effects on metaphor comprehension in reading

Subjects read target sentences preceded by either short or long context that induced either a metaphoric or a literal target reading. As had been found by Ortony, Schallert, Reynolds, and Antos (1978), metaphoric targets were comprehended about as quickly as literals when context was long, but more slowly than literals when context was short. The latter result may have been due to the failure of computing a conceptual relationship between short context and metaphoric target; targets unrelated to prior context took as long to comprehend as metaphoric targets. Another experiment showed that metaphorically expressed targets were read more quickly when they followed metaphorically expressed context than when they followed literal context, but literal targets were read quickest when they followed literal context. These results are discussed within a schema framework and within a “process priming” hypothesis.     

The role of prior context in the comprehension of abstract and concrete sentences

Summary In two experiments the hypothesis was tested that abstract sentences become as easy to understand as concrete sentences when given appropriate prior context. Paragraph contexts and sentences followed by a comprehension question were presented in a speeded reading task. The results showed that the abstract sentences remained significantly more difficult to process than the concrete sentences in both experiments. The hypothesis that the concreteness effect is a function of differential context availability was therefore not supported. It was proposed that lexical differences and/or differences in ease of propositional integration may underlie the effect.     

Relational processing and working memory capacity in comprehension of relative clause sentences

Previous research has indicated that the cognitive load imposed by tasks in various content domains increases with the complexity of the relational information processed. Sentence comprehension entails processing noun-verb relations to determine who did what to whom. The difficulty of object-extracted relative clause sentences might stem from the complex noun-verb relations they entail. Across three studies, participants read 16 types of object- and subject-extracted relative clause sentences at their own pace and then responded to a comprehension question for each sentence. Relational processing was assessed using a premise integration task or a Latin square task. These tasks predicted comprehension of object-relatives before and after controlling for subject-relatives. Working memory (WM) capacity was assessed using reading span or forward and backward digit span tests. WM tasks predicted comprehension of object-relatives before but not after controlling for subject-relatives. Comprehension of object-relatives relied more heavily on a domain-general capacity to process complex relations than on WM capacity.     

The effects of linearity on sentence comprehension in oral and silent reading

This study examined the effects of linearity of language (e.g., de Saussure, 1916/1972) on performance on a sentence comprehension task, manipulating (a) presentation method (simultaneous, phrase, or flow) and (b) reading method (oral or silent reading). The study also examined the predictive powers of the digit span test (DST) and the reading span test (RST) for task performance. Fifty‐four undergraduate and graduate students participated in the experiment. The results showed that the DST score predicted performance on both garden‐path (GP) and non‐garden‐path (NGP) sentences, whereas the RST score did so only for GP sentences. This suggests that the sentence comprehension task requires not only comprehension but also temporarily storing verbal information, and that the RST score reflects the degree of tolerance for deviation from linearity. The results also revealed that silent reading has an advantage over oral reading in simultaneous presentation and vice versa in flow presentation, whereas the difference between reading methods disappeared in phrase presentation. This suggests that oral and silent reading require different strategies to facilitate sentence comprehension.     

Effects of accelerated reading rate on syntactic processing of Hebrew sentences: electrophysiological evidence

The present study was designed to investigate whether accelerated reading rate influences the way adult readers process sentence components with different grammatical functions. Participants were 20 male native Hebrew-speaking college students aged 18-27 years. The processing of normal word strings was examined during word-by-word reading of sentences having subject-verb-object (SVO) syntactic structure in self-paced and fast-paced conditions. In both reading conditions, the N100 (late positive) and P300 (late negative) event-related potential (ERP) components were sensitive to such internal processes as recognition of words' syntactic functions. However, an accelerated reading rate influenced the way in which readers processed these sentence elements. In the self-paced condition, the predicate-centered (morphologically based) strategy was used, whereas in the fast-paced condition an approach that was more like the word-order strategy was used. This new pattern was correlated with findings on the shortening of latency and the increasing of amplitudes in both N100 and P300 ERP components for most sentence elements. These changes seemed to be related to improved working memory functioning and maximized attention.     

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 inference in children's comprehension and memory for sentences

In a series of studies, young children often failed to construct and remember inferred relationships which they were capable of understanding. A cued recall procedure was employed to assess the relative effectiveness of implicit and explicit word prompts for sentence memory. The implicit cues were much less effective than the explicit cues for 6–7 yr old children while the cue types did not differ for 11–12 yr olds. Instructions to imitate the actions described by the sentences eliminated the memory difference for the young children. Developmental improvement in spontaneous inferential operations and intentional plans to remember are mechanisms which appear to yield an elaborated memory representation and greater access routes through indirect and implied relationships.     

The role of sublexical graphemic processing in reading

Dual-route models of reading postulate the existence of two separate mechanisms: The lexical route allows words to be recognized in their holistic form, and the sublexical route proceeds by converting the written sublexical entities of a word or a nonword into their corresponding phonological equivalents. Sublexical reading is assumed to require three stages of processing: graphemic parsing, graphophonemic conversion, and phoneme blending. This study provides evidence in favor of the existence of a graphemic parsing process which occurs prior to grapheme-phoneme conversion. A group of normal subjects read nonwords which contained multiletter graphemes significantly more slowly than graphemically simple nonwords. These results, best interpretable in the context of a recent dual-route model of reading, confirm previous data obtained in pathology which suggest the functional independence of this cognitive procedure.     

The effects of processing requirements on neurophysiological responses to spoken sentences

Ten English speaking subjects listened to sentences that varied in sentential constraint (i.e., the degree to which the context of a sentence predicts the final word of that sentence) and event-related potentials (ERPs) were recorded during the presentation of the final word of each sentence. In the Control condition subjects merely listened to the sentences. In the Orthographic processing condition subjects merely listened to the sentences. In the Orthographic processing condition subjects decided, following each sentence, whether a given letter had been present in the final word of the preceding sentence. In the Phonological processing condition the subjects judged whether a given speech sound was contained in the terminal word. In the Semantic processing condition subjects determined whether the final word was a member of a given semantic category. A previous finding in the visual modality that the N400 component was larger in amplitude for low constraint sentence terminations than for high was extended to the auditory modality. It was also found that the amplitude of a N200-like response was similarly responsive to contextual constraint. The hypothesis that N400 amplitude would vary significantly with the depth of processing of the terminal word was not supported by the data. The "N200" recorded in this language processing context showed the classic frontocentral distribution of the N200. The N400 to spoken sentences had a central/centroparietal distribution similar to the N400 in visual modality experiments. It is suggested that the N400 obtained in these sentence contexts reflects an automatic semantic processing of words that occurs even when semantic analysis is not required to complete a given task. The cooccurrence and topographical dissimilarity of the "N200" and N400 suggest that the N400 may not be a delayed or a generic N200.     

The comprehension of anomalous sentences: evidence from structural priming

We report three experiments investigating how people process anomalous sentences, in particular those in which the anomaly is associated with the verb. We contrast two accounts for the processing of such anomalous sentences: a syntactic account, in which the representations constructed for anomalous sentences are similar in nature to the ones constructed for well-formed sentences; and a semantic account, in which the representations constructed for anomalous sentences are erroneous, or altogether missing, and interpretation is achieved on the basis of semantic representations instead. To distinguish between these accounts, we used structural priming. First, we ruled out the possibility that anomaly per se influences the magnitude of the priming effect: Prime sentences with morphologically incorrect verbs produced similarly enhanced priming (lexical boost) to sentences with the same correct verbs (Exp. 1). Second, we found that prime sentences with a novel verb (Exp. 2) or a semantically and syntactically incongruent verb (Exp. 3) produced a priming effect, which was the same as that produced by well-formed sentences. In accord with the syntactic account, we conclude that the syntactic representations of anomalous sentences are similar to those constructed for well-formed sentences. Our results furthermore suggest that lexically-independent syntactic information is robust enough to produce well-formed syntactic representations during processing without requiring aid from lexically-based syntactic information.     

Individual differences in susceptibility to the effects of speech on reading comprehension

Individuals with high working memory capacity (WMC) are less distracted by task‐irrelevant speech than others. The mechanism behind this relationship, however, is not well understood, and it has only been found in a few paradigms. We used a Number updating task to measure WMC and two suppression mechanisms (immediate and delayed), and tested how they were associated with individual differences in susceptibility to the effects of speech on reading comprehension. The results revealed a negative relationship between WMC and susceptibility to speech distraction. Of the two suppression mechanisms, only immediate suppression was associated with speech distraction, suggesting that susceptibility to distraction is determined by the ability to immediately suppress the irrelevant speech. Furthermore, the relationship between WMC and speech distraction was mediated by the immediate suppression mechanism. The implications of these results and possible explanations of similar results found in other paradigms are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

Anxiety and the spelling and use in sentences of threat/neutral homophones

The disambiguation of threat/neutral homophones was investigated in high- and low-trait anxiety subjects who had been exposed to either a positive or a negative mood manipulation procedure. Subjects were required first to spell each auditorily presented word and second, to generate and speak a sentence using the word. Difference indices were calculated for the spelling and the sentence usage data, i.e. the number of threat minus neutral interpretations. Examination of these indices revealed that subjects exposed to the negative mood manipulation procedure produced relatively more threat than neutral interpretations (for both spelling and sentence usage) than did subjects exposed to the positive mood manipulation procedure. Multiple regression analyses revealed that both the trait anxiety and mood manipulation variables contributed significantly to the prediction of the difference index on the spelling task. In the analysis of the use of homophones in sentences, only the mood manipulation variable contributed significantly to the prediction of the difference index on the sentence usage task.     

Reciprocal teaching and self-monitoring of strategy use: effects on reading comprehension

Reciprocal teaching (RT) is an instructional procedure to teach students cognitive strategies that might lead to improved reading comprehension. However, self-monitoring (SM) strategy use can optimize instruction of comprehension. Thus, the present study analyzed: (a) the efficacy of RT in regular classes and (b) the efficacy of RT + SM of strategy use. A sample of 59 students in the fourth year of primary education was selected: 19 children were selected as an RT condition, 18 as an RT + SM condition, while the remaining 22 made up the comparison group. Two types of comprehension measures were used: tasks of specific effects (getting the main idea, writing a summary, comprehension-monitoring test) and transfer effect measures (standardised tests, word meaning inference, and free recall). Thus, the results show that both the RT condition and the RT + SM condition benefited from the instruction, performing better than the comparison group in measures of specific effects and in some of the transfer effect measures. This result shows that SM is not a necessary component in the instruction of reading comprehension with RT.
