Lexical ambiguity resolution in good and poor comprehenders: An eye fixation and self-paced reading study in primary school children.

To investigate the use of context and monitoring of comprehension in lexical ambiguity resolution in children, the authors asked 10- to 12-year-old good and poor comprehenders to read sentences consisting of 2 clauses, 1 containing the ambiguous word and the other the disambiguating information. The order of the clauses was reversed so that disambiguating information either preceded or followed the ambiguous word. Context use and comprehension monitoring were examined by measuring eye fixations (Experiment 1) and self-paced reading times (Experiment 2) on the ambiguous word and disambiguating region. The results of Experiment 1 and 2 showed that poor comprehenders made use of prior context to facilitate lexical ambiguity resolution as effectively as good comprehenders but that they monitored their comprehension less effectively than good comprehenders. Good comprehenders corrected an initial interpretation error on an ambiguous word and restored comprehension once they encountered the disambiguating region. Poor comprehenders failed to deal with this type of comprehension failure. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Temporal References and Temporal Relations in Sentence Comprehension.

The author investigated the interpretation of temporal references during comprehension of sentences containing a main and subordinate clause. Experiments 1 and 2 examined state and event subordinate clauses, respectively, and showed that subordinate temporal references overlapping with or close to the time of the main clause event were read faster than nonoverlapping distant references. Experiment 3 examined temporal references in nonsubordinate main clauses and confirmed that temporal relations between main and subordinate clauses were established on-line in the previous experiments. Experiment 4 independently manipulated temporal overlap and distance and suggested that event and state clauses are processed according to distinct temporal parameters. The results are explained by the contingency relations that events and states establish with other discourse events. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of age, speed of processing, and working memory on comprehension of sentences with relative clauses.

Two hundred participants, 50 in each of four age ranges (19–29, 30–49, 50–69, 70–90) were tested for working memory, speed of processing, and the processing of sentences with relative clauses. In Experiment 1, participants read four sentence types (cleft subject, cleft object, subject-subject, subject-object) in a word-by-word, non-cumulative, self-paced reading task and made speeded plausibility judgments about them. In Experiment 2, participants read two types of sentences, one of which contained a doubly center embedded relative clause. Older participants' comprehension was less accurate and there was age-related slowing of online processing times in all but the simplest sentences, which increased in syntactically complex sentences in Experiment 1. This pattern suggests an age-related decrease in the efficiency of parsing and interpretation. Slower speed of processing and lower working memory were associated with longer online processing times only in Experiment 2, suggesting that task-related operations are related to general speed of processing and working memory. Lower working memory was not associated with longer reading times in more complex sentences, consistent with the view that general working memory is not critically involved in online syntactic processing. Longer online processing at the most demanding point in the most demanding sentence was associated with better comprehension, indicating that it reflects effective processing under some certain circumstances. However, the poorer comprehension performance of older individuals indicates that their slower online processing reflects inefficient processing even at these points.

Individual differences in reading to summarize expository text: Evidence from eye fixation patterns.

Eye fixation patterns were used to identify reading strategies of adults as they read multiple-topic expository texts. A clustering technique distinguished 4 strategies that differed with respect to the ways in which readers reprocessed text. The processing of fast linear readers was characterized by the absence of fixations returning to previous text. Slow linear readers made lots of forward fixations and reinspected each sentence before moving to the next. The reading of nonselective reviewers was characterized by look backs to previous sentences. The distinctive feature of topic structure processors was that they paid close attention to headings. They also had the largest working-memory capacity and wrote the most accurate text summaries. Thus, qualitatively distinct reading strategies are observable among competent, adult readers.

A theory of reading: From eye fixations to comprehension.

Presents a model of reading comprehension that accounts for the allocation of eye fixations of 14 college students reading scientific passages. The model deals with processing at the level of words, clauses, and text units. Readers made longer pauses at points where processing loads were greater. Greater loads occurred while readers were accessing infrequent words, integrating information from important clauses, and making inferences at the ends of sentences. The model accounts for the gaze duration on each word of text as a function of the involvement of the various levels of processing. The model is embedded in a theoretical framework capable of accommodating the flexibility of reading. (70 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The role of prior knowledge and elaboration in text comprehension and memory: a comparison of self-generated elaboration and text-provided elaboration

Four experiments investigated the interactive effect of text-provided elaborations and prior knowledge on text comprehension and memory. Subjects read 28 episodes, half of which were associated with well-known people and the other half with unknown people. In Experiment 1, text-provided elaborations enhanced recall only when the reader did not have a high level of prior knowledge. The findings from Experiment 1 were hypothesized to be the result of readers generating relevant elaborations during text comprehension. Experiment 2 supported this hypothesis by providing evidence of self-generated elaborations. The results from Experiments 3 and 4 extended these findings by showing that readers with high prior knowledge automatically generate causally relevant elaborations when the sentences have a low relation.     

Eye movements of young and older adults during reading.

The eye movements of young and older adults were tracked as they read sentences varying in syntactic complexity. In Experiment 1, cleft object and object relative clause sentences were more difficult to process than cleft subject and subject relative clause sentences; however, older adults made many more regressions, resulting in increased regression path fixation times and total fixation times, than young adults while processing cleft object and object relative clause sentences. In Experiment 2, older adults experienced more difficulty than young adults while reading cleft and relative clause sentences with temporary syntactic ambiguities created by deleting the that complementizers. Regression analyses indicated that readers with smaller working memories need more regressions and longer fixation times to process cleft object and object relative clause sentences. These results suggest that age-associated declines in working memory do affect syntactic processing. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Eye movements of young and older adults while reading with distraction.

The authors used eye-tracking technology to examine young and older adults' online performance in the reading in distraction paradigm. Participants read target sentences and answered comprehension questions following each sentence. In some sentences, single-word distracters were presented in either italic or red font. Distracters could be related or unrelated to the target text. Online measures, including probability of fixation, fixation duration, and number of fixations to distracting text, revealed no age differences in text processing. However, young adults did have an advantage over older adults in overall reading time and text comprehension. These results provide no support for an inhibition deficit account of age differences in the reading in distraction paradigm, but are consistent with J. Dywan and W. E. Murphy's (1996) suggestion that older adults are less able than the young to distinguish target and distracter information held in working memory.

Syntactic prediction in language comprehension: Evidence from either...or.

Readers' eye movements were monitored as they read sentences in which two noun phrases or two independent clauses were connected by the word or (NP-coordination and S-coordination, respectively). The word either could be present or absent earlier in the sentence. When either was present, the material immediately following or was read more quickly, across both sentence types. In addition, there was evidence that readers misanalyzed the S-coordination structure as an NP-coordination structure only when either was absent. The authors interpret the results as indicating that the word either enabled readers to predict the arrival of a coordination structure; this predictive activation facilitated processing of this structure when it ultimately arrived, and in the case of S-coordination sentences, enabled readers to avoid the incorrect NP-coordination analysis. The authors argue that these results support parsing theories according to which the parser can build predictable syntactic structure before encountering the corresponding lexical input.

Visuospatial cues for reinstating mental models in working memory during interrupted reading.

Reading involves constructing a mental representation in long-term working memory of the world described by the text. Disrupting short-term working memory can interfere with the maintenance of mental models (sets of retrieval cues) needed to access these representations, producing detrimental effects on reading time. In two experiments, subjects read passages that included pairs of coreferential sentences interrupted by unrelated text. As in previous research, reading times increased for the first sentence after the interruption, likely reflecting a reinstatement process for mental models in working memory. In the present research, pictures were provided as visuospatial cues to aid the reinstatement process. The interruption effect was found to be smaller with pictures related to the passages than with unrelated pictures (Experiment 1) or titles (Experiment 2); however, both of these effects occurred only for slow readers. The authors hypothesize that slow readers take the time needed to integrate visuospatial information into their mental models, providing more resilient access to long-term working memory.

How prior knowledge, WMC, and relevance of information affect eye fixations in expository text.

This study examined how prior knowledge and working memory capacity (WMC) influence the effect of a reading perspective on online text processing. In Experiment 1, 47 participants read and recalled 2 texts of different familiarity from a given perspective while their eye movements were recorded. The participants' WMC was assessed with the reading span test. The results suggest that if the reader has prior knowledge related to text contents and a high WMC, relevant text information can be encoded into memory without extra processing time. In Experiment 2, baseline processing times showed whether readers slow down their processing of relevant information or read faster through the irrelevant information. The results are discussed in the light of different working memory theories. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Predictable texts and interactive-compensatory hypotheses: Evaluating individual differences in reading ability, context use, and comprehension.

Examined the word-recognition and comprehension processes of 36 1st graders as they read a predictable text. Interactive-compensatory predictions related to comprehension were evaluated. Results suggest that when reading predictable texts, attention for both good and poor readers is available for comprehension processing but for different reasons. Consistent with predictions from the interactive-compensatory model by K. E. Stanovich (1980), good readers were able to attend to the meaning of a story because of automatic, context-free word-recognition skills. Poor readers were able to attend to the meaning of a story because of their automatic use of repetitive sentence context to facilitate word recognition. Thus, predictable texts may be appropriately used to provide comprehension opportunities for poorer readers. Predictable texts may give these students opportunities to engage in inferential reasoning and other comprehension processes, opportunities that infrequently occur because poor readers' attention is usually occupied by word-recognition demands.

Reading strategies for children and adults: A quantitative model.

Developed an additive model to account for reading times for 2 different reading tasks (reading for retention and reading for comprehension). The reading strategies of 48 college students and 64 5th graders and individual differences between fast and slow readers were examined. Ss were assumed to have processors that handle the lexical, structural, and meaning information in sentences. The various task, age, and reading speed groups were hypothesized to use the 3 processors for differing amounts of time. The model was supported by word-by-word reading times for 80 sentences and by 9 empirical indices of lexical, structural, and meaning attributes of text. Results show that for skilled adult Ss, relatively more time was spent processing structure in the retention task, and meaning in the comprehension task. Fifth graders had not fully mastered the connection between task demands and linguistic processors shown by adults, and thus used mixtures of the adult strategies.

Using temporal information to construct, update, and retrieve situation models of narratives.

Four experiments explored how readers use temporal information to construct and update situation models and retrieve them from memory. In Experiment 1, readers spontaneously constructed temporal and spatial situation models of single sentences. In Experiment 2, temporal inconsistencies caused problems in updating situation models similar to those observed previously for other dimensions of situation models. In Experiment 3, merely implied temporal order information was inferred from narratives, affecting comprehension of later sentences like explicitly stated order information. Moreover, inconsistent temporal order information prevented the creation and storage in memory of an integrated situation model. In Experiment 4, a temporal inconsistency increased processing time even if readers were unable to report the inconsistency. These results confirm the significance of the temporal dimension of situation models. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Reading spaced and unspaced Chinese text: Evidence from eye movements.

Native Chinese readers' eye movements were monitored as they read text that did or did not demark word boundary information. In Experiment 1, sentences had 4 types of spacing: normal unspaced text, text with spaces between words, text with spaces between characters that yielded nonwords, and finally text with spaces between every character. The authors investigated whether the introduction of spaces into unspaced Chinese text facilitates reading and whether the word or, alternatively, the character is a unit of information that is of primary importance in Chinese reading. Global and local measures indicated that sentences with unfamiliar word spaced format were as easy to read as visually familiar unspaced text. Nonword spacing and a space between every character produced longer reading times. In Experiment 2, highlighting was used to create analogous conditions: normal Chinese text, highlighting that marked words, highlighting that yielded nonwords, and highlighting that marked each character. The data from both experiments clearly indicated that words, and not individual characters, are the unit of primary importance in Chinese reading.

The effect of word frequency, word predictability, and font difficulty on the eye movements of young and older readers.

Young adult and older readers' eye movements were recorded as they read sentences containing target words that varied in frequency or predictability. In addition, half of the sentences were printed in a font that was easy to read (Times New Roman) and the other half were printed in a font that was more difficult to read (Old English). Word frequency, word predictability, and font difficulty effects were apparent in the eye movement data of both groups of readers. In the fixation time data, the pattern of results was the same, but the older readers had larger frequency and predictability effects than the younger readers. The older readers skipped words more often than the younger readers (as indicated by their skipping rate on selected target words), but they made more regressions back to the target words and more regressions overall. The E-Z Reader model was used as a platform to evaluate the results, and simulations using the model suggest that lexical processing is slowed in older readers and that, possibly as a result of this, they adopt a more risky reading strategy.

Individual Differences in the Inference of Word Meanings From Context: The Influence of Reading Comprehension, Vocabulary Knowledge, and Memory Capacity.

Two studies investigated the ability to use contextual information in stories to infer the meanings of novel vocabulary by 9-10-year-olds with good and poor reading comprehension. Across studies, children with poor reading comprehension were impaired when the processing demands of the task were greatest. In Study 2, working memory capacity was related to performance, but short-term memory span and memory for the literal content of the text were not. Children with poor reading comprehension were not impaired in learning novel vocabulary taught through direct instruction, but children with both weak reading comprehension and vocabulary were. Implications for the relation between vocabulary development and text comprehension are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Increased processing enhances calibration of comprehension.

Two experiments investigated whether increased processing increases the relation between test performance predictions and test performance, i.e., increases calibration of comprehension. The amount of processing of text was manipulated by having subjects read intact text or text with deleted letters. In Experiment 1, intact versus deleted letters were manipulated within subjects, and subjects made either comprehension ease or test prediction ratings. Paragraphs with deleted letters produced higher correlations between predictions and test performance than did intact paragraphs. Better calibration with more processing was not observed for ratings of comprehension ease. In Experiment 2, in a between-subjects design, the prediction results were replicated; calibration was better for text with deleted letters than for intact text. The results show that subjects can predict performance on text material with greater than chance accuracy and that these predictions are better when subjects do more active processing during reading.

The Effect of Relevance Instructions on Reading Time and Learning.

The authors examined the effect of prereading relevance instructions on reading time and learning for 2 types of text. Experiment 1 found that relevance instructions increased learning for relevant segments without increasing reading time when reading a scientific text sentence by sentence on a computer. In contrast, the same segments were learned less well and took longer to read when nonrelevant. Experiment 2 replicated the findings when individuals read an informational narrative text. These findings supported the no increased effort hypothesis, which states that relevant information is learned better without additional effort when readers are told what is relevant prior to reading. In contrast, nonrelevant information is learned less well. The authors attribute these effects to the goal-focusing nature of relevance instructions.
