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)     

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.

Text skimming: The process and effectiveness of foraging through text under time pressure.

Is Skim reading effective? How do readers allocate their attention selectively? The authors report 3 experiments that use expository texts and allow readers only enough time to read half of each document. Experiment 1 found that, relative to reading half the text, skimming improved memory for important ideas from a text but did not improve memory of less important details or of inferences made from information within the text. Experiment 2 found no advantage of skimming over reading the first or second half of every paragraph. Two final experiments using a hierarchical, Website-like layout of documents showed that the advantage of skimming found in Experiment 1 was dependent on the linkages between pages and, thus, the ease with which participants could navigate through the text. Data on page-by-page reading times and eye-tracking analyses from Experiment 2 indicated that Skim readers spent more time reading text that was earlier in the paragraph, toward the top of the page and in an earlier page of the document. These findings were interpreted as evidence in support of a “satisficing” account of skimming process. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Text comprehension, memory, and learning

People are often able to reproduce a text quite well but are unable to use the information in the text for other purposes. Factors that help people to reproduce a text have been studied for some time. This article explores ways that enable people to learn from texts. Content overlap between a text and the reader's prior knowledge is identified as one factor, and methods are proposed to identify whether a text is suitable for readers with given background knowledge. For readers with low background knowledge, a text should be as coherent and explicit as possible to facilitate learning. However, data are presented to show that for readers with adequate background knowledge, texts with coherence gaps that stimulate constructive activities are in fact better for learning.     

Reading both high-coherence and low-coherence texts: Effects of text sequence and prior knowledge.

Determined if (1) the advantage for the low-coherence text is due to inferences made while reading, or alternatively, due to inferences generated during testing as a result of less information being available from the low-coherence text; (2) the inferences must rely on prior knowledge, or if inferences based on the text (or recently presented information) are sufficient; and (3) reading 2 different text versions is advantageous for readers. Ss were 80 university students who were assigned to 1 of 4 conditions representing if the Ss read the high-coherence text followed by either the high- or low-coherence text, or the low-coherence text followed by either the high-or the low-coherence text. Methodology involved reading the texts, answering questions about the text, and answering prior knowledge questions. The results indicate that high-knowledge readers benefited from the low-coherence only text when it was read first. Further, low-knowledge readers benefited from the high-coherence text, regardless of whether it was read first, second, or twice. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The influence of connectives on young readers' processing and comprehension of text.

Connectives are cohesive devices that signal the relations between clauses and are critical to the construction of a coherent representation of a text's meaning. The authors investigated young readers' knowledge, processing, and comprehension of temporal, causal, and adversative connectives using offline and online tasks. In a cloze task, 10-year-olds were more accurate than 8-year-olds on temporal and adversative connectives, but both age groups differed from adult levels of performance (Experiment 1). When required to rate the “sense” of 2-clause sentences linked by connectives, 10-year-olds and adults were better at discriminating between clauses linked by appropriate and inappropriate connectives than were 8-year-olds. The 10-year-olds differed from adults only on the temporal connectives (Experiment 2). In contrast, online reading time measures indicated that 8-year-olds' processing of text is influenced by connectives as they read, in much the same way as 10-year-olds'. Both age groups read text more quickly when target 2-clause sentences were linked by an appropriate connective compared with texts in which a connective was neutral (and), inappropriate to the meaning conveyed by the 2 clauses, or not present (Experiments 3 and 4). These findings indicate that although knowledge and comprehension of connectives is still developing in young readers, connectives aid text processing in typically developing readers.

Effect of topic label repetition and importance on reading time and recall of text.

College students read one of 2 versions of a chapter of text in which target topic labels appeared either with high frequency or low frequency. In 2 experiments, frequent repetition of a token in the passage increased the likelihood that the token was listed as a main topic, regardless of the importance of the topic. Also, in Experiment 2, readers with lower verbal ability spent more time reading high-frequency/low-importance material than did high-verbal-ability readers. These experiments show that readers with low prior knowledge are more likely to make use of surface cues to identify important elements of text.

Understanding knowledge effects on attitude-behavior consistency: The role of relevance, complexity, and amount of knowledge.

The role of properties of attitude-relevant knowledge in attitude- behavior consistency was explored in 3 experiments. In Experiment 1, attitudes based on behaviorally relevant knowledge predicted behavior better than attitudes based on low-relevance knowledge, especially when people had time to deliberate. Relevance, complexity, and amount of knowledge were investigated in Experiment 2. It was found that complexity increased attitude- behavior consistency when knowledge was of low-behavioral relevance. Under high-behavioral relevance, attitudes predicted behavior well regardless of complexity. Amount of knowledge had no effect on attitude- behavior consistency. In Experiment 3, the findings of Experiment 2 were replicated, and the complexity effect was extended to behaviors of ambiguous relevance. Together, these experiments support an attitude inference perspective, which holds that under high deliberation conditions, people consider the behavioral relevance and dimensional complexity of knowledge underlying their attitudes before deciding to act on them.

The role of interest in learning from scientific text and illustrations: On the distinction between emotional interest and cognitive interest.

A textbook lesson may be made more interesting by promoting emotional interest through adding entertaining text and illustrations or by promoting cognitive interest through adding signals for structural understanding such as summary illustrations with captions. In Experiment 1, skilled readers who read summary text and illustrations about the process of lightning performed worse on retention of important information and on transfer when entertaining text, illustrations, or both were added. In Experiment 2, skilled readers rated entertaining text and illustrations relatively high in emotional interest and low in cognitive interest and rated summary illustrations and text relatively low in emotional interest and high in cognitive interest. The results suggest benefits of cognitive interest over emotional interest for helping students learn scientific explanations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Enhancing the recall of text: Knowledge mapping training promotes implicit transfer.

Spatial–semantic displays, such as knowledge maps, are becoming more prevalent in educational settings (D. R. Dansereau & D. Newbern, 1997). In particular, knowledge maps have been found to be effective communication aids and study devices. Although explicit use of these displays can be effective, it has not been clear whether or not experience with these displays improves the manner in which people interact with other information formats. These experiments were designed to investigate whether mapping training helped people learn from text when not explicitly using a mapping strategy. In Experiment 1, college students trained with knowledge maps recalled more macro-level ideas from two text passages compared with participants who were not given the training. In Experiment 2, training facilitated recall of both macro- and micro-level ideas. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The role of perspective in the accessibility of goals during reading.

An implicit assumption of several causal reasoning models is that readers adopt the goals of a narrative's protagonist during text comprehension. In apparent violation of this assumption, readers participating in Experiment 1 of the present study drew inferences relevant to a protagonist's goal even when that goal was already satisfied from the perspective of the protagonist. In Experiments 2 and 3, participants were explicitly asked to view the text situation from the point of view of the protagonist. In this case, the goals of the reader and the protagonist should be the same. In these experiments, participants focused on the goals of the protagonist only when those goals had not been satisfied from the perspective of the protagonist. These results are discussed in terms of reader- and character-based perspectives and in terms of text characteristics that cue perspective taking.

Unpriming: The Deactivation of Thoughts Through Expression.

Unpriming is a decrease in the influence of primed knowledge following a behavior expressing that knowledge. The authors investigated strategies for unpriming the knowledge of an answer that is activated when people are asked to consider a simple question. Experiment 1 found that prior correct answering eliminated the bias people normally show toward correct responding when asked to answer yes-no questions randomly. Experiment 2 revealed that prior answering intended to be random did not unprime knowledge on subsequent attempts to answer randomly. Experiment 3 found that exposure to the correct answer did not influence the knowledge bias but that exposure to the incorrect answer increased bias. Experiment 4 revealed that merely expressing the answer for oneself was sufficient to unprime knowledge. Experiment 5 found that each item of activated knowledge needs to be unprimed specifically, in that correctly answering 1 question does not reduce the knowledge bias in randomly answering another.

Learning of nondomain facts in high- and low-knowledge domains.

Research on expertise has repeatedly documented that experts learn new information better than do novices, but only when the information is relevant to the expert's domain. It was found in Experiment 1 that participants showed superior learning and recall of a large quantity of new, non-domain-relevant facts about concepts within their domain of high knowledge than about concepts for which they had low domain knowledge. Experiment 2 investigated whether the participants' superior recall of new facts related to concepts within their domain of high knowledge was due to the number of prior facts associated with the concept or to the prior frequency of repetition of those concepts. It was found that participants' recall of new facts was better for concepts with 5 prior associated facts than for concepts with a single prior association but that the number of previous repetitions of each concept did not affect the level of recall for the new facts.

The effect of verbal elaborations on memory in young and older adults

The Stein paradigm was used to examine the circumstances under which verbal elaborations enhance memory in young and older adults. Subjects studied target adjectives that were embedded in one of three sentence contexts that varied in elaboration of the subject-adjective relationship: (1) nonelaborated base sentences; (2) base sentences with semantically consistent, but arbitrary verbal, elaborations; and (3) base sentences with explanatory verbal elaborations that clarified the significance of the subject-adjective relationship. The presence of the elaborations was varied at encoding and retrieval, and cued recall of the target adjectives was tested with incidental and intentional learning procedures. In Experiments 1A and 1B, explanatory elaborations at encoding and retrieval yielded the largest memorial facilitation for both young and older adults, and the benefit was comparable for the incidental and intentional learning measures. In Experiment 2, age-related differences in recall were minimal with explanatory elaborations at encoding and retrieval, but larger age differences occurred in the nonelaborated comparison conditions. In Experiment 3, explanatory elaborations present at encoding but not at retrieval enhanced recall when the original Stein stimuli were used, but not with the present stimuli. The implications of these results with regard to the mnemonic efficacy of verbal elaborations for young and older adults are discussed.     

Generation and precision of elaboration: Effects on intentional and incidental learning.

Across three experiments adults were presented either base sentences containing arbitrary relations (e.g., The fat man read the sign) or base sentences accompanied by a precise elaboration that made clear the significance of the particular type of man doing the action (e.g., The fat man read the sign warning about thin ice). Subjects either read the sentence alone or answered a question accompanying the sentence. Why did that particular man do that? accompanied base sentences; How does the last part of the sentence make clear why that particular man did that? accompanied precisely elaborated sentences. Both intentional and incidental learning were studied. The positive effects of providing precise elaborations were moderate in size and confined to incidental learning. Much larger incidental and intentional learning gains followed generation of elaborations in response to questions, with generated precise elaborations facilitating acquisition slightly better than generated imprecise elaborations.

Effect of mobilizing prior knowledge on learning from text.

68 5th graders studied a 125-word passage consisting of 18 statements about a fictional fox. Afterwards, Ss tried to reproduce the text and, 1 wk later, took a multiple-choice test. Prior to reading, half the Ss mobilized relevant preexisting knowledge. Results indicate that mobilizing significantly facilitated retention of information inconsistent with prior knowledge but did not affect retention of congruous information. A topically organized passage was not better remembered than a topically disorganized one. Results are discussed with reference to assimilation encoding theory and the failure of students to relate discourse to prior knowledge.
