The effect of prior knowledge on understanding from text: Evidence from primed recognition

We investigated the relationships that readers with different levels of prior knowledge established between the elements of a procedural text. More specifically, we examined the relationships between the goal, a sequence of actions, and their outcome. Our hypothesis was that the main difference between the prior knowledge organisation of beginner, intermediate, and advanced participants can be described in terms of these relationships. To test this hypothesis, we investigated participants' reading times and used a primed recognition task with the goal as prime and both the outcome and the actions as targets. As we assumed, results indicated that the beginner participants did not establish a relationship between the goal and the outcome when they were distant in the surface structure of the text, whereas the intermediate and advanced participants did. The Construction-Integration model of Kintsch (1998) was used to simulate the recognition results and to reproduce the effect of prior knowledge on the retrieval of textual information.     

The recognition of geometrically transformed text

In two experiments it was found that the difficulty of recognizing geometrically transformed text varied with the transformation imposed upon it. In one experiment the text was in English and the Ss were native speakers of English; in the second, the text was in Hebrew and the Ss were native speakers of Hebrew. The two languages are read in opposite directions. Nevertheless, the order of difficulty of the trans-formations was similar with the two texts. The results are interpreted to show that the visual systems contains “trans-formation operators” as well as the more widely publicized “detectors.”     

Asymmetries in peer interaction: The effect of social representations of gender and knowledge asymmetry on children's cognitive development

This study examines the role of social representations of gender and knowledge as sources of asymmetry on the features of children's interactions as well as on their cognitive development. The research was carried through an innovative pre‐test, first interaction, second interaction, post‐test design. One hundred fifty‐nine children of the same age (6.5–7.5 years old) but of different levels of knowledge of a spatial‐transformation task collaborated in same‐sex and opposite‐sex dyads to find a joint solution. In the first interaction, a child less developmentally advanced (NC) had to work with a child more developmentally advanced (TC), whereas in the second interaction of the same gender composition, the same NC had to work with a fresh NC. Cognitive progress was assessed using pre‐test to post‐test gains. The results revealed that the gender composition of the pairs and knowledge asymmetry influence not only the behavioral patterns and strategies that each partner employs in the interaction but also the cognitive outcomes of the children. These findings shed more light to the process through which socio‐cognitive conflict gets resolved, which was considered until now a “black box.” Copyright © 2012 John Wiley & Sons, Ltd.     

Mental models as representations of text

A theory of text representation is outlined which suggests that a text is encoded in a mental model that contains representations of only those individuals and events that are relevant to the interpretation of the text in question. Such models are constructed on-line in response to cues in the text and with reference to knowledge about the world. An experiment is reported which demonstrates that mental models represent the events most probably described in a text. The results confirm previous findings that memory for the content of a passage is not based on the construction of one of its linguistically motivated representations. However, unlike most previous findings, they do support a positive proposal about the nature of the representations on which memory for content is based.     

The effect of text coherence and modality on metamemory judgements

This study examined the effects of text coherence and modality on the metamemory judgements of Ease of Learning (EOL) and Judgement of Learning (JOL), and on the object-level measure of recall. Previous work found that sentence material set in a coherent, ordered text context was not judged as more memorable than that presented in a context of sentences in a disordered sequence, even though an ordered sequence helped recall (Shaddock & Carroll, 1997). The current study modified Shaddock and Carroll's design by changing the texts used from expository to narrative text. The metamemory judgements and recall were now found to be significantly more sensitive to material learned in an ordered sequence than to material learned in a disordered sequence. Also, JOLs and recall were more sensitive to material that was originally learned in an auditory mode (spoken presentation) than in a visual mode (verbal presentation). The results are discussed in terms of a cue-utilisation approach to metamemory judgements.     

The production and recognition of typological argumentative text markers

A series of experiments on children and adults were conducted to define the features and workings of argumentative discourse. Oral and written arguments were analyzed for the complexity of the argument support structure and the presence of typological argumentation markers (certainty modals, value judgments, etc.). Subjects were asked to assess the argumentativity of texts that did or did not contain typical argumentation markers. At about age ten, children can produce and recognize a ‘minimal argumentative structure,’ in which the speaker takes a stance and supports it with text that derives its argumentativity from the presence of this stance). However, full mastery of the negotiation process, that involves acknowledgment of the opponent's stance (generally through the use of counterarguments) is not present before the ages of 15 to 16. The minimal argumentative structure continues to develop with age and gain complexity. Certain situations are more conductive to the production of elaborate argumentative discourse, such as a genuinely controversial topic with an unfamiliar adult addressee whose stance is not known and whose reaction is thus unpredictable. Here speakers produce complex arguments while still leaving room for negotiation. Overall, certain argumentation markers can be identified in all argumentative text. these markers can be used to characterize stages of development of argumentative discourse. A number of issues remain unexplored, including: What other (implicit...) devices do speakers use to convince their audience? Why is the capacity to put argumentation in writing acquired at such a late stage of development?     

Core knowledge and its limits: The domain of food

Adults, preschool children, and nonhuman primates detect and categorize food objects according to substance information, conveyed primarily by color and texture. In contrast, they perceive and categorize artifacts primarily by shape and rigidity. The present experiments investigated the origins of this distinction. Using a looking time procedure, Experiment 1 extended previous findings that rhesus macaques (Macaca mulatta) generalize learning about novel food objects by color over changes in shape. Six additional experiments then investigated whether human infants show the same signature patterns of perception and generalization. Nine-month-old infants failed to detect food objects in accord with their intrinsic properties, in contrast to rhesus monkeys tested in previous research with identical displays. Eight-month-old infants did not privilege substance information over other features when categorizing foods, even though they detected and remembered this information. Moreover, infants showed the same property generalization patterns when presented with foods and tools. The category-specific patterns of perception and categorization shown by human adults, children, and adult monkeys therefore were not found in human infants, providing evidence for limits to infants’ domains of knowledge.     

Mental representations of affect knowledge

The circumplex structure derived from similarity ratings of affect words is assumed to be a conceptual representation of affect anchored in semantic knowledge. Recently, it been suggested that this structure is not based on semantic knowledge at all, but may instead reflect a type of episodic knowledge: The degree to which emotions covary in everyday life. In two experience-sampling studies, we compared the semantic and the episodic hypotheses by comparing participants' similarity ratings to the observed covariations in their own affective experience computed from their momentary reports. In Study 2, participants also provided estimates of the degree to which their emotions covaried. Evidence from both studies indicate that similarity judgements are related both to semantic and episodic information, indicating that a pure episodic account of similarity ratings, and the mental representation of affect that they reflect, is untenable.     

Updating geographical knowledge: principles of coherence and inertia

In 2 experiments, the authors investigated how representations of global geography are updated when people learn new location information about individual cities. Participants estimated the latitude of cities in North America (Experiment 1) and in the Old and New Worlds (Experiment 2). After making their first estimates, participants were given information about the latitudes of 2 cities and asked to make a second set of estimates. Both the first and second estimates revealed evidence for psychologically distinct geographical subregions that were coordinated, in an ordinal sense, across the Atlantic Ocean. Further, the second estimates were affected by the nature of the physical adjacency between regions (e.g., the southern U.S. and Mexico) and by accurate location information about distant, but coordinated, subregions (e.g., the southern U.S. and Mediterranean Europe). The data provide support for a framework for making geographical estimates in which people strike a balance between 2 principles: the need to keep their knowledge base coherent, and the inertial tendency to resist changing the knowledge base unless it is necessary to maintain coherence.     

Effects of sentence importance on text recall and recognition: The inferential hypothesis

Abstract

The hypothesis that sentences with important information are more likely to be remembered than less important sentences because the former are inferred to a greater extent than the latter, was explored. In three previous studies, sentence importance in the structure of texts had been established: Main sentences were assigned higher importance ratings, and recalled and recognised better than secondary sentences. In the present experiment, the subjects read two out of six 500-word texts at their own pace and performed a recall or a recognition test 8 min and 7 days later. Different text versions were written; in each version, one main sentence and one secondary sentence were removed from the original texts. me results showed: (1) a higher false alarm rate and intrusion proportion for main sentences compared to secondary sentences; (2) superior net recall scores (after deduction of intrusions) and memory scores (after correction for guessing) for main sentences; but (3) equivalent net recognition scores (after deduction of false alarms) and discrimination (d') scores in the immediate test, and a superior net recognition and discrimination of secondary sentences in the delayed test. It is concluded that the inferential hypothesis is consistent with most of the results, and that the probability of coding and retention does not differ as a function of sentence importance, though main information may be retrieved more easily than less important information.     

Text recall and text recognition with and without a title

Abstract: Recall and recognition memory for a text were investigated in two conditions: in one, subjects could understand the text well because they were presented with the title of the text prior to reading it; in the other, they could not understand the text so well because they were not presented with the title. Results showed that recall was better and sentence recognition more accurate when subjects had understood the text. A 1-h delay of the memory test after reading decreased recall performance, but not recognition performance. Different memory representations may have been operating when subjects had understood the text from when they had not.     

Connectionist and rule-based representations of expert knowledge

Research in computer science has led to the development of two broad classes of models of knowledge representation: rule-based and connectionist systems. Both techniques solve the same abstract problem, that is, the assignment of cases to classes. Connectionist modeling techniques have been applied to three classification situations in which one would expect rule-based models to be applicable. Two of the situations involved the diagnosis of problems in and operation of a fictitious power plant. The third situation involved the classification of misconceptions held by elementary physics students. Connectionist modeling developed adequate simulations of behavior in all three cases.     

The computational implementation of the landscape model: Modeling inferential processes and memory representations of text comprehension

The complexity of text comprehension demands a computational approach to describe the cognitive processes involved. In this article, we present the computational implementation of the landscape model of reading. This model captures both on-line comprehension processes during reading and the off-line memory representation after reading is completed, incorporating both memory-based and coherence-based mechanisms of comprehension. The overall architecture and specific parameters of the program are described, and a running example is provided. Several studies comparing computational and behavioral data indicate that the implemented model is able to account for cycle-by-cycle comprehension processes and memory for a variety of text types and reading situations.     

Context and structure: The nature of students' knowledge about three spatial diagram representations

The authors investigated whether college students possess abstract rules concerning the applicability conditions for three spatial diagrams that are important tools for thinking—matrices, networks, and hierarchies. A total of 127 students were asked to select which type of diagram would be best for organising the information in each of several short scenarios. The scenarios were written using three different story contexts: (a) neutral, presenting a real-life situation but not cueing a particular representation; (b) abstract, presenting only variable names and relations; and (c) incongruent, in which the context and informational structure cued different representations. The results indicated above-chance performance on the abstract scenarios, as well as comparable performance on the abstract and neutral context scenarios. In a follow-up study in which eight students thought out loud while selecting diagrams for the abstract scenarios, there were almost no references to concrete examples. The results of these studies suggest that students possess abstract rules concerning the applicability conditions for matrices, networks, and hierarchies.     

Revising what readers know: Updating text representations during narrative comprehension

Reading comprehension involves not just encoding information into memory, but also updating and revising what is already known or believed. For example, as narrative plots unfold, readers often must revise the expectations they have constructed from earlier portions of text to successfully comprehend later events. Evidence suggests that such revision is by no means guaranteed. In three experiments, we examined conditions that influence readers' revision of trait-based models for story characters. Trait models are particularly relevant for examining such revision because they demonstrate resistance to change. We specifically assessed whether task instructions and content-driven refutations of earlier information would enhance the likelihood of revision. In Experiment 1, instructions to carefully consider the appropriateness of story outcomes generally facilitated revision. In Experiment 2, we removed those instructions; revision occurred only when refutations included sufficient explanation to suggest that updating was necessary. Experiment 3 further supported the influence of instructions on readers' propensities to revise. These results are informative with respect to the mechanisms that guide readers' moment-by-moment comprehension of unfolding narratives.     

Ontological commitments of frame-based knowledge representations

Synthese - In this paper, I shall assess the ontological commitments of frame-based methods of knowledge representation. Frames decompose concepts (statements, theories) into recursive...     

Prior knowledge and recognition

The purpose of this series of experiments was to determine if and when word recognition would depend on the number of related concepts represented in permanent memory. Words defining either large or small rhyme or meaning categories were studied and tested under various conditions. The results indicated that rhyme category size influenced recognition whenever rhyme was emphasized during both study and testing phases. Words belonging to larger rhyme sets were not recognized as well as those belonging to smaller rhyme sets. In contrast, meaning-related set size had no effect on recognition. These and other findings indicate that the breadth of prior knowledge can influence recognition but only under limited conditions that reactivate this knowledge at test.     

Primacy of functional knowledge in semantic representations: The case of living and nonliving things

In 3 experiments, participants decided whether sensory and functional features were true of living and nonliving concepts. In Experiments 1 and 2, concepts were presented twice: test phase followed study phase after either 3 min (Experiment 1) or 3 s (Experiment 2). At test, concepts were paired with the same feature as that at study, or a different feature from either the same modality (within-modality priming) or another modality (cross-modality priming). In both experiments functional decisions were faster than sensory decisions for living and nonliving concepts. Whilst no semantic priming occurred between study and test in Experiment 1, the shorter study–test interval of Experiment 2 did lead to test phase semantic priming. Here there was greater within- than cross-modality priming for sensory decisions, but equivalent within- and cross-modality priming for functional decisions owing to significantly greater facilitation of functional decisions from prior sensory decisions than vice versa. Experiment 3 involved a single verification phase: For half the participants the feature name preceded the concept name, and for half the concept name preceded the feature name. The functional processing advantage persisted irrespective of presentation order. Results suggest that functional information is central to the representation of all concepts: Function is processed faster than sensory information and is activated obligatorily.
