Effects of Personal Epistemology on the Understanding of Multiple Texts

We examined whether the text understanding of students holding naïve and sophisticated epistemological beliefs was differentially affected by text format, also controlling for effects of gender, word decoding, and prior knowledge on understanding. The participants were 39 Norwegian first-year teacher students, and the topic of reading was attention-deficit hyperactivity disorder (ADHD). It was found that only readers holding sophisticated epistemological beliefs displayed adequate understanding when reading multiple, partly conflicting, texts about ADHD, whereas students holding naïve epistemological beliefs gained better understanding when reading a single textbook-like source with identical content. This finding, however, depended on the level of understanding being measured by the criterial task, with only the task measuring deeper situational text understanding showing an interaction between epistemological beliefs and text format. This study provides evidence that not only knowledge itself, but also personal beliefs about knowledge, may enhance or constrain deeper understanding of multiple texts.     

The effect of perspective-taking on reasoning about strong and weak belief-relevant arguments

This study investigated whether perspective-taking reduces belief bias independently of argument strength. Belief bias occurs when individuals evaluate belief-consistent arguments more favourably than belief-inconsistent arguments. Undergraduates (n = 93) read arguments that varied with respect to belief-consistency (i.e., belief-consistent or belief-inconsistent) and strength (i.e., strong or weak) about the topic of climate change. After participants read each argument, those in the perspective-taking condition rated the argument's strength from a perspective of a climate scientist and then from their own perspectives, whereas those in the no perspective-taking condition only rated the arguments from their own perspectives. Perspective-taking eliminated belief bias for weak arguments, but not for strong arguments. Theoretical and practical implications of the results are discussed, and directions for future research are provided.     

Memory for Textual Conflicts Predicts Sourcing When Adolescents Read Multiple Expository Texts

This study investigated whether memory for conflicting information predicted mental representation of source-content links (i.e., who said what) in a sample of 86 Norwegian adolescent readers. Participants read four texts presenting conflicting claims about sun exposure and health. With differences in gender, prior knowledge, and interest controlled for, and with self-reported critical reading strategies also included in a multiple regression analysis, it was found that the better participants remembered that the texts presented conflicting claims on the issue, the more likely they were to include source-content links in their mental representations of the texts.     

Situation models,propositions, and the fan effect

According to theories of language comprehension, people can construct multiple levels of representation: the surface form, the propositional text base, and the situation model. In this study, I looked at how the referential nature of memory probes affects the experience of retrieval interference. All the subjects memorized sentences about objects in locations (e.g., “The potted palm is in the hotel”). When memory probes were sentences and, therefore, referential and most closely associated with the situation model level, no interference was observed during retrieval for information that could be integrated into a common situation model. In contrast, interference was observed in such cases when the memory probes were concept pairs (POTTED PALM-HOTEL) and hence not directly referential. This is interpreted to mean that nonreferential memory probes involve surface form and text base representations more than do referential sentence probes.     

Personal theories, intellectual ability, and epistemological beliefs: adult age differences in everyday reasoning biases

Age-related differences in everyday reasoning biases were explored. In each of 2 social domains, examination of theoretical beliefs and biases along 2 dimensions of scientific reasoning, involving the law of large numbers and the evaluation of experimental evidence, revealed that, across age groups, scientific reasoning was used to reject evidence that contradicted prior beliefs; relatively cursory reasoning was used to accept belief-consistent evidence. Biased reasoning was more common among middle-aged and older adults than among young adults. Dispositions to engage in analytic processing were negatively related to biases, but intellectual abilities and bias were not related. The findings support a 2-process view of adult cognitive development and suggest that the tendency to rely on heuristic information processing increases with age.     

Multi-level mental representations of written,auditory, and audiovisual text in children and adults

We examined whether the comprehension of narrative texts differed between auditory, audiovisual, and written text presentations in a sample of 8- and 10-year-olds and adults. Based on multi-level theories of text comprehension that assume text comprehension to involve at least three levels of mental representation, we applied a sentence recognition task that enabled the separate assessment of the memory of the text surface, text base, and the situation model. Results indicate that 8-year-olds benefit from audiovisual and auditory text presentations in comparison with written text presentations in terms of their memory of situation model information. For 10-year-olds and adults, their text comprehension did not differ between audiovisual, auditory, and written text presentations. Additionally, the mode of text presentation had no effect on the memory of text surface and text base information.     

Situation models and aging

Younger and older adults were tested for their ability to process and retrieve information from texts. The authors focused on the construction and retrieval of situation models relative to other types of text representations. The results showed that during memory retrieval, younger adults showed superior memory for surface form and textbase knowledge (what the text was), whereas older adults had equivalent or superior memory for situation model information (what the text was about). The results also showed that during reading, older and younger adults were similar in their sensitivity to various aspects of the texts. Overall, these findings suggest that although there are age-related declines in the processing and memory for text-based information, for higher level representations, these abilities appear to be preserved. Several possibilities for why this is the case are discussed, including an in-depth consideration of one possibility that involves W. Kintsch's (1988) construction-integration model.     

Effects of perspective and belief on analytic reasoning in a scientific reasoning task

The purpose of these studies was to test the hypothesis that changing perspectives from one's own to another's promotes the engagement of analytic processing and, in turn, reduces the impact of beliefs. In two experiments participants evaluated research vignettes containing belief-consistent and belief-inconsistent conclusions, and indicated whether the data supported a correlation between two variables. Consistent with our hypothesis, the tendency to endorse correlations consistent with prior belief was reduced when participants evaluated the data from the researcher's perspective relative to their own. We also administered the Actively Open Minded Thinking (AOT) scale (Stanovich & West, 2007, 2008), which did not predict belief effects on our task. We did however observe that the AOT was reliably associated with different response strategies: high AOT scorers were more inclined to choose ambiguous response options, such as “no conclusion is warranted”, whereas low scorers evinced a preference for more determinate options (e.g., there is no relationship between the two variables). We interpret our findings in the context of dual process theories of reasoning and from a Bayesian perspective.     

Learning from Conflicting Texts: The Role of Intertextual Conflict Resolution in Between-Text Integration

The present study examined the effect of intertextual conflict resolution on learning from conflicting texts. In two experiments, participants read sets of two texts under the condition of being encouraged either to resolve a conflict between the texts' arguments (the resolution condition) or to comprehend the arguments (the comprehension condition). Experiment 1 found that participants in the resolution condition surpassed participants in the comprehension condition at the understanding of the controversial subjects and succeeded in the understanding of the intertextual relationships. Experiment 2 found that participants in the resolution condition recalled compatible and incompatible information from the texts more than did participants in the comprehension condition. The recalled information from one text was also positively correlated with that from the opposite text. These results suggest that intertextual conflict resolution facilitates successful integration of conflicting arguments in texts in terms of the documents model framework (e.g., Britt & Rouet, 2012).     

The effects of self‐explaining when learning with text or diagrams

Self‐explaining is an effective metacognitive strategy that can help learners develop deeper understanding of the material they study. This experiment explored if the format of material (i.e., text or diagrams) influences the self‐explanation effect. Twenty subjects were presented with information about the human circulatory system and prompted to self‐explain; 10 received this information in text and 10 in diagrams. Results showed that students given diagrams performed significantly better on post‐tests than students given text. Diagrams students also generated significantly more self‐explanations that text students. Furthermore, the benefits of self‐explaining were much greater in the diagrams condition. To discover why diagrams can promote the self‐explanation effect, results are interpreted with reference to the multiple differences in the semantic, cognitive and affective properties of the texts and diagrams studied.     

Why do delayed summaries improve metacomprehension accuracy?

We showed that metacomprehension accuracy improved when participants (N = 87 college students) wrote summaries of texts prior to judging their comprehension; however, accuracy only improved when summaries were written after a delay, not when written immediately after reading. We evaluated two hypotheses proposed to account for this delayed-summarization effect (the accessibility hypothesis and the situation model hypothesis). The data suggest that participants based metacomprehension judgments more on the gist of texts when they generated summaries after a delay; whereas, they based judgments more on details when they generated summaries immediately after reading. Focusing on information relevant to the situation model of a text (the gist of a text) produced higher levels of metacomprehension accuracy, which is consistent with situation model hypothesis.     

Learning From Text

A framework is presented for distinguishing between two types of mental representations formed while reading a text: The textbase is a representation built in the process of comprehension, and a situation model is built to represent the situation described in the text. Two studies are reported that explore the relative contribution of each type of representation and their interaction during problem solving. In the first, grade school children solved easy and hard arithmetic word problems of three types: change, combine, and compare. When asked to recall, reconstruction of the problems occurred and was related to solution performance. Children tended to recall problems already solved on the basis of the situation model used in solutions and not by reproducing the original textbase. In the second study, college students formed mental maps while reading two types of texts describing the layout of a town: The survey text described the town in geographical terms, and the route version presented the same information as a series of instructions for driving through the town. A dichotomy was seen between remembering the text and learning from it; the former was dependent on text coherence, and the latter depended on the formation of a situation model. Implications for instruction are discussed in terms of clarifying goals for the use of texts and distinguishing between instruction aimed toward recall and instruction aimed toward learning.     

Hemispheric processing of anaphoric inferences: the activation of multiple antecedents

This research investigates the hemispheric processing of anaphors when readers activate multiple antecedents. Participants read texts promoting an anaphoric inference and performed a lexical decision task to inference-related target words that were consistent (Experiment 1) or inconsistent (Experiment 2) with the text. These targets were preceded by constrained or less constraining text and were presented to participants' right visual field-left hemisphere or to their left visual field-right hemisphere. In Experiment 1, both hemispheres showed facilitation for consistent antecedents and the right hemisphere showed an advantage over the left hemisphere in processing antecedents when preceded by less constrained text. In Experiment 2, the left hemisphere only showed negative facilitation for inconsistent antecedents. When readers comprehend text with multiple antecedents: both hemispheres process consistent information, the left hemisphere inhibits inconsistent information, and the right hemisphere processes less constrained information.     

Drawing is Integrating: An Examination of Students’ Graphic Representations of Multiple Texts

In this study, integration, or students’ connection formation across texts, was examined across two tasks: when undergraduates were asked to complete a writing assignment and a novel, diagram construction task. While the writing assignment asked students to compose an argument based on multiple texts, the diagram construction task asked students to visually represent a set of eight conflicting texts and the relations among them. The Documents Model Framework (DM) was used to code undergraduates’ written responses and diagrams for the type of multiple text representations they featured (i.e., mush models, separate representations models, and documents models of multiple texts). Moreover, written responses and diagrams were coded for the specificity at which they integrated texts, corresponding to the formation of evidentiary, thematic, and contextual relations. Limited associations were found between college students’ written responses and the diagrams constructed. Implications for understanding multiple text integration are discussed.     

Different Words for the Same Concept: Learning Collaboratively From Multiple Documents

This study investigated how varying the lexical encodings of technical terms in multiple texts influences learners' dyadic processing of scientific-related information. Fifty-seven pairs of college students read journalistic texts on depression. Each partner in a dyad received one text; for half of the dyads the partner's text contained different lexical encodings of the same concepts; for the other half the lexical encodings and texts were identical. They then read a case report on first signs of depression. Communicating via a chat room, each dyad had to write a causal diagnosis and suggest a treatment. Results showed that dyads in the different-encoding condition explicitly elaborated the meaning of technical terms more often, produced more differentiated answers, and acquired more knowledge. It is concluded that deliberately switching different words for the same underlying content, and engaging students in discussion of that content, influences learners' discourse and promotes scientific/conceptual understanding.     

Altering comprehension: The effect of biasing titles on text comprehension

Titles can alter the comprehension of a text by affecting the selection of information from a text and the organization of this information in memory. Text comprehension is assumed to involve an organizational process that results in the formation of a text base, an ordered list of semantic units—propositions. The text base can be used as a retrieval scheme to reconstruct the text. Procedures for assigning propositions as more relevant to some themes as compared to other themes are developed and applied to texts. Texts with biasing titles were used in an experiment to demonstrate that immediate free recall is biased toward the theme emphasized in the title. The comprehension process which is guided by the text’s thematical information is described.     

A context-dependent representation model for explaining text repetition effects

The purpose of this article is to review abstract and episodic models of text repetition effects, describe the research supporting these types of models, and propose a new model called thecontextdependent representation model, which can explain both abstract-like and episodic-like repetition effects. The basic assumptions of the model are that the surface form and textbase are represented in a context-independent manner, and a coherent situation model binds together the surface features and the textbase and leads to context-dependent representation. When the situation model is well developed, it limits repetition benefits to semantically or contextually similar texts. This produces contextdependent repetition effects, which are functionally similar to episodic repetition effects. When the situation model is not well developed or not task relevant, repetition benefits are not limited to contextually similar texts. This produces context-independent repetition effects, which are functionally similar to abstract repetition effects. The context-dependent representation model provides a theoretical basis for explaining past research, and it can serve as a guide for future research aimed at understanding text repetition effects as well as text comprehension and memory.     

Understanding and Integrating Multiple Science Texts: Summary Tasks are Sometimes Better Than Argument Tasks

One of the major challenges of a knowledge society is that students as well as other citizens must learn to understand and integrate information from multiple textual sources. Still, task and reader characteristics that may facilitate or constrain such intertextual processes are not well understood by researchers. In this study, we compare the effects of summary and argument essay tasks when undergraduates read seven different texts on a particular scientific topic, finding that an instruction to write summaries may lead to better understanding and integration than an instruction to write argument essays. We discuss several possible explanations for this result. We also found that beliefs about the certainty of knowledge in some instances can moderate the effect of task on comprehension performance.     

Text representations as reflected in patterns of cognitive distance

Subjects performed a task that involved learning a text and then indicating, for each of a series of pairs of words, whether they belonged to the same sentence of that text. When the principle of argument overlap or causal coherence was the sole integrative factor in a text, negative response times and error rates reflected distances in the network representation predicted by the principle. When the two principles predicted conflicting representations for a text, response times and error rates reflected the predictions of the principle of argument overlap. The results were interpreted as suggesting that network connections predicted by the two principles are both present in the memory representations of texts and that causal connections are recorded at a more abstract level of representation than are argument overlap connections.     

Semantic associations and elaborative inference

In this article, a theoretical framework is proposed for the inference processes that occur during reading. According to the framework, inferences can vary in the degree to which they are encoded. This notion is supported by three experiments in this article that show that degree of encoding can depend on the amount of semantic-associative information available to support the inference processes. In the experiments, test words that express possible inferences from texts are presented for recognition. When testing is delayed, with other texts and test items intervening between a text and its test word, performance depends on the amount of semantic-associative information in the text. If the inferences represented by the test words are not supported by semantic associates in the text, they appear to be only minimally encoded (replicating McKoon & Ratcliff, 1986), but if they are supported by semantic associates, they are strongly encoded. With immediate testing, only 250 ms after the text, performance is shown to depend on semantic-associative information, not on textual information. This suggests that it is the fast availability of semantic information that allows it to support inference processes.
