Probe-detection times during the reading of easy and difficult text.

Two experiments were conducted to determine the effects of text difficulty on cognitive capacity demands. In Experiment 1, subjects read easy and difficult text when a secondary task was either present or absent. Text was presented one word at a time, and rereading was prevented by erasing each word after it had been read. Prior studies have indicated that cognitive capacity demands decrease as text difficulty increases (e.g., Britton, Westbrook, & Holdredge, 1978). In contrast to this, the main results of Experiment 1 revealed shorter visual-probe-detection times during the reading of easy text than during the reading of difficult text. Analyses of word-reading times showed that difficult text was read slower than easy text, irrespective of probe application. Experiment 2 compared visual-probe detection with auditory-probe detection. The results again showed shorter probe reaction times (RTs) during the reading of easy text than during the reading of difficult text, irrespective of probe type. There were, however, effects of probe type on the reading time of words following the visual probe. The results were taken as evidence that the reading of difficult text requires more capacity than the reading of easy text and that probes may incur modality-specific and modality-independent capacity demands.

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.

Integration of topic and subordinate information during reading.

Four experiments examined how readers integrate subordinate information with relevant context as they read. Ss read texts a sentence at a time with occasional interruptions lasting 30 sec. Following a distractor task, they resumed reading after being reminded of the topic sentence of the last paragraph they read (topic cue condition), being reminded of the last sentence they had read (local cue condition), or receiving no reminder of what they had been reading (no cue condition). Reading times on the 1st sentence following interruption were faster in the topic and local cue conditions than in the no cue condition (1) when the topic and local cues supplied missing referents for the target sentences, (2) when the target sentences were written to be understood as independent statements, and (3) whether the target sentences were embedded in short or long texts. Results are interpreted as demonstrating that readers integrate subordinate information with relevant topics, as well as with the immediate local context.

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.

The effects of reading purpose and working memory capacity on the processing of expository text.

The extent to which low- and high-WMC (working memory capacity) readers adjust cognitive processes to fit the reading purpose was examined. Participants performed a verbal protocol task as they read an expository text under 1 of 2 reading purpose conditions, entertainment or study, and then completed a free-recall task. When reading to study, low-WMC readers emphasized less demanding processes over more demanding processes to a greater extent than high-WMC readers and recalled less. When reading for entertainment, patterns of processes and recall were similar across readers. Thus, all readers adjusted processing to fit the reading purpose; however, when reading for study, low-WMC readers emphasized processes that were the least demanding on their resources but not necessarily beneficial for recall.

Reading voices and hearing text: Talker-specific auditory imagery in reading.

A series of experiments was conducted to determine if linguistic representations accessed during reading include auditory imagery for characteristics of a talker's voice. In 3 experiments, participants were familiarized with two talkers during a brief prerecorded conversation. One talker spoke at a fast speaking rate, and one spoke at a slow speaking rate. Each talker was identified by name. At test, participants were asked to either read aloud (Experiment 1) or silently (Experiments 1, 2, and 3) a passage that they were told was written by either the fast or the slow talker. Reading times, both silent and aloud, were significantly slower when participants thought they were reading a passage written by the slow talker than when reading a passage written by the fast talker. Reading times differed as a function of passage author more for difficult than for easy texts, and individual differences in general auditory imagery ability were related to reading times. These results suggest that readers engage in a type of auditory imagery while reading that preserves the perceptual details of an author's voice.

Is there semantic interference in delayed naming?

The semantic interference effect in the picture–word interference task is interpreted as an index of lexical competition in prominent speech production models. Janssen, Schirm, Mahon, and Caramazza (2008) challenged this interpretation on the basis of experiments with a novel version of this task, which introduced a task-switching component. Participants either named the picture or read the word, depending on the word's color. Janssen et al. reported semantic interference in picture naming, regardless of whether the word appeared simultaneously with the picture (immediate naming) or 1,000 ms after the picture (delayed naming). Because picture name retrieval is completed in less than 1,000 ms, the finding in delayed naming was taken as evidence against the lexical competition account. In 3 sets of experiments conducted in German and English, we tested for semantic effects in Janssen et al.'s task-switching version and in the standard picture–word interference task. Using identical materials, we obtained sizeable interference effects in the standard task (Experiments 2, 4, and 6) but no effects in the task-switching version (Experiments 1, 3, and 5). When the word reading trials of the task-switching version were replaced with no-go trials (Experiment 7), semantic interference reemerged in immediate naming but was still absent in delayed naming. The experiments question the reliability of Janssen et al.'s critical finding and suggest that theoretical inferences about the origin of semantic effects in the standard picture–word interference task based on results from the task-switching version used by Janssen et al. are difficult to draw.

A comparison of fast-rate, slow-rate, and silent previewing interventions on reading performance

Researchers investigated the effects of three different previewing interventions on the oral reading rates of 12 junior and senior high school students with learning disabilities. Under fast-rate listening previewing (FRLP), students were instructed to follow silently as experimenters read from a text at an average rate that was 77.7% faster than the students' current oral reading rate. During slow-rate listening previewing (SRLP), students followed along as experimenters read at an average rate that was 22.5% faster than the students' reading rate. Students were instructed to read passages silently under silent previewing (SP). Immediately following each previewing intervention, students read the same passage aloud. The number of words read correctly per minute and the number of errors per minute served as dependent variables. The results showed statistically significant decreases in error rates under SRLP and SP. The results also showed that SRLP resulted in statistically significantly fewer errors per minute than FRLP. These results suggest that orally reading while students follow along at a rate much higher than their current reading rates may not be as beneficial as reading aloud at slower rates.     

The tongue-twister effect in reading Chinese.

Two studies demonstrate a visual tongue-twister effect (TTE) in Chinese and add support to the assumption that reading in any writing system engages a phonological memory system. Exp 1 showed that for both oral and silent reading, Ss took longer to read texts with repeated initial phonemes (IPs) than to read control stories with mixed IPs. Exp 2 verified the phonemic nature of the TTE in a dual task situation in which Ss had to retain a string of digits while reading a sentence. The results showed a specific-phoneme interference such that Ss took longer to read the texts when digits and words had the same IPs than when they had different phonemes. Both studies provide evidence that the source of the TTE in both Chinese and English is phonological interference rather than visual confusion. They confirm the highly general nature of phonological involvement in skilled sentence reading. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The relationship of style difficulty, practice, and ability to efficiency of reading and to retention.

Two groups of Ss, one of high and one of low mechanical ability, read a technical passage before an eye-movement camera. An "easy" style and a "hard" style passage were used, and Ss read the passage once or three times. Reading efficiency measures collected were words read per second and per fixation; retention measures were scores on modified recall and word recognition tests. The high ability group scored better on all measures than the low ability group; three readings yielded superior scores on the retention measures; and the "easy" style gave higher scores on the reading efficiency and modified recall measures.

Improvement in reading rate under independent and difficult text levels: Influences on word and comprehension skills.

Improving reading rate can be difficult for poor readers. In this experiment, we investigated the impact of improvement in reading rate on other aspects of reading, including word recognition, decoding, vocabulary, and comprehension. Poor readers in Grades 2 or 4 (N = 123) were randomly assigned to 1 of 3 conditions: practice reading text at their independent reading level (92%–100% word reading accuracy), practice reading text at a difficult reading level (80%–90% accuracy), or an untreated control. Students in practice conditions read aloud to an adult listener who assisted with difficult words. Before, midway, and following 20 weeks of treatment, we assessed improvement in reading rate, word recognition, decoding, vocabulary, and comprehension across conditions and determined the impact of improved rate on comprehension. We found significant differences favoring the treatment groups in rate, word recognition, and comprehension, but not in decoding or vocabulary. We found no significant differences in growth between levels of text difficulty. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Development of the interplay between automatic processes and cognitive resources in reading.

An account was tested of the development of the interplay between automatic processes and cognitive resources in reading. According to compensatory-encoding theory, with advancing skill, readers increasingly keep automatic processes from faltering and provide timely, accurate data to working memory by pausing, looking back, rereading, and compensating in other ways when automatic processes fail. Reading skill profiles (e.g., word naming, semantic access, working memory capacity) were obtained from 71 third graders, 68 fifth graders, and 72 seventh graders from a university lab school or a public school (ages 7 to 15; 146 Caucasians, 61 African Americans, 2 Native Americans, 2 Latino Americans). Children participated in an unrestricted reading task (no time or performance pressure) and were randomly assigned to 1 of 2 levels of 3 experimental manipulations of restriction on reading: time pressure or no pressure, constant reading rate or variable reading rate, read silently or read aloud. Regression analyses revealed that developmental level and restriction moderated the reading skill level-comprehension relationship, and restriction lowered comprehension when it overwhelmed skills, especially for younger readers. Verbally inefficient readers compensated most often, and older readers compensated most efficiently. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Neighborhood effects in reading aloud: New findings and new challenges for computational models.

A word from a dense neighborhood is often read aloud faster than a word from a sparse neighborhood. This advantage is usually attributed to orthography, but orthographic and phonological neighbors are typically confounded. Two experiments investigated the effect of neighborhood density on reading aloud when phonological density was varied while orthographic density was held constant, and vice versa. A phonological neighborhood effect was observed, but not an orthographic one. These results are inconsistent with the predominant role ascribed to orthographic neighbors in accounts of visual word recognition and reading aloud. Consistent with this interpretation, 6 different computational models of reading aloud failed to simulate this pattern of results. The results of the present experiments thus provide a new understanding of some of the processes underlying reading aloud, and new challenges for computational models.

Reprocessing text: Indirect measures of word and message level processes.

In three experiments we examined word- and text-level transfer after different reading experiences. Experiment 1 showed that facilitation in the later perceptual identification of a word occurs when that word was orginally read as part of a word set, but not when it was read as part of a meaningful text. Further, the word-to-word transfer effect exhibited the hallmarks of data-driven processing. Experiments 2 and 3 showed that transfer at the text level occurs when the reprocessing measure involves the entire text, rather than words taken from the text. This text reprocessing effect also exhibited data-driven indicators and was indifferent to the subjects' reading strategies. It was specific to the text originally read, with no generalization to texts of the same structure. The results, discussed in terms of P. A. Kolers' (see record 1976-00491-001) views of skilled reading, suggest caution in interpreting transfer measures when the original and reprocessing tasks are at different linguistic levels.

Semantic, phonological, and mediated priming in reading and lexical decisions.

Four experiments were conducted to investigate whether semantic activation of a concept spreads to phonologically and graphemically related concepts. In lexical decision or self-paced reading tasks, subjects responded to pairs of words that were semantically related (e.g., light–lamp), that rhymed (e.g., lamp–lamp), or that combined both of these relations through a mediating word (e.g., light–lamp). In one version of each task, test lists contained word–word pairs (e.g., light–lamp) as well as nonword–word (e.g., pown–table) and word–nonword pairs (e.g., month–poad); in another version, test lists contained only word–word pairs. The lexical decision and self-paced reading tasks were facilitated by semantic and rhyming relations regardless of the presence or absence of nonwords on the test lists. The effect of the mediated relation, however, depended on the presence of nonwords among the stimuli. When only words were included, there was no effect of the mediated relation, but when nonwords were included, lexical decision and self-paced reading responses were inhibited by the mediated relation. These inhibitory effects are attributed to processes occurring after lexical access, and the relative advantages of the self-paced reading task are discussed.

Covert operations: Orthographic recoding as a basis for repetition priming in word identification.

When a word is generated from a semantic cue, coincident orthographic visualization of that word may cause priming on a subsequent perceptual identification test. A task was introduced that required subjects to visualize the orthographic pattern of auditorily presented words. When used at study, this task produced a pattern of priming similar to that produced by a generate study task. When used at test, equal priming on the orthographic task was produced by read and generate study tasks but not by a generate study task that failed to invite orthographic visualization. Priming on perceptually based word identification tests that results from a generate study episode may be largely due to orthographic recoding of the target rather than to conceptual processing.

Automatic activation of phonological information in reading: evidence from the semantic relatedness decision task

A semantic relatedness decision task was used to investigate whether phonological recording occurs automatically and whether it mediates lexical access in visual word recognition and reading. In this task, subjects read a pair of words and decided whether they were related or unrelated in meaning. In Experiment 1, unrelated word-homophone pairs (e.g., LION-BARE) and their visual controls (e.g., LION-BEAN) as well as related word pairs (e.g., FISH-NET) were presented. Homophone pairs were more likely to be judged as related or more slowly rejected as unrelated than their control pairs, suggesting phonological access of word meanings. In Experiment 2, word-pseudohomophone pairs (e.g., TABLE-CHARE) and their visual controls (e.g., TABLE-CHARK) as well as related and unrelated word pairs were presented. Pseudohomophone pairs were more likely to be judged as related or more slowly rejected as unrelated than their control pairs, again suggesting automatic phonological recording in reading.     

Task effects on eye movements during reading.

The present study examined how proofreading and reading-for-comprehension instructions influence eye movements during reading. Thirty-seven participants silently read sentences containing compound words as target words while their eye movements were being recorded. We manipulated word length and frequency to examine how task instructions influence orthographic versus lexical–semantic processing during reading. Task instructions influenced both temporal and spatial aspects of eye movements: The initial landing position in words was shifted leftward, the saccade length was shorter, first fixation and gaze duration were longer, and refixation probability was higher during proofreading than during reading for comprehension. Moreover, in comparison to instructions for reading for comprehension, proofreading instructions increased both orthographic and lexical–semantic processing. This became apparent in a greater word length and word frequency effect in gaze duration during proofreading than during reading for comprehension. The present study suggests that the allocation of attentional resources during reading is significantly modulated by task demands. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Aging, memory load, and resource allocation during reading.

To test the notion that aging brings an inability to self-initiate processing, the authors investigated the effects of memory load on online sentence understanding. Younger and older adults read a series of short passages with or without a simultaneous updating task, which would be expected to deplete resources by consuming memory capacity. Regression analyses of word-by-word reading times onto text variables within each condition were used to decompose reading times into resources allocated to the array of word-level and textbase-level processes needed for comprehension. Among neither the young nor the old were word-level processes disrupted by a simultaneous memory load. However, older readers showed relatively greater levels of resource allocation to conceptual integration than the younger adults when under load, regardless of working-memory span or task priority. These results suggest that the ability to self-initiate the allocation of processing resources during reading is preserved among older readers.
