Home Issues 20, Vol. Les informations relevant du modèle de situation sont mieux comprises dans les versions cohérentes explicites que dans les versions non cohérentes implicites. Le connecteur causal tend à améliorer le rappel et la compréhension seulement dans les versions cohérentes explicites. Dans la discussion, on souligne la nécessité de mieux examiner comment les experts, comparés aux novices, traitent les connecteurs causaux au cours même de la causal in a sentence.
Experts and novices read a biology text whose paragraphs were or were not accompanied by questions. Connectives and questions during reading increased target sentence reading time. During reading, the coherent explicit text versions benefited from better comprehension of information related to the situation model, but not the recall of textbase-related information. The Connective tended to improve text recall and comprehension but only for the coherent explicit versions.
More specific research on on-line processing should further examine how experts process causal connectives as compared to novices. One case where this can occur is when the text contains inconsistencies which are difficult to resolve, particularly when the reader is a novice in the domain. One way of doing so consists of adding new propositions and arguments to the original textbase to supply background information. Usually, the original text version is called the implicit version and the revised version, the explicit version.
These devices enhance the text for two reasons. Moreover, connectives e. Causal connectives may prompt readers to search for knowledge in long-term-memory in order to restore local or global text incoherence. For example, Caron et al. Maury et al. This search may have facilitate integration and memorization. If not, the causal connective is like an empty signal. So one can expect experts to benefit more than novices from such causal connectives during text comprehension.
This result suggests that experts generate backward what is hawthorne effect in sociology inferences that facilitate text comprehension. It is possible that questions direct attention not only to target information but also to all the content of the passage, and that this directed attention is accompanied by deeper processing and longer reading times van den Broek et al.
The procedure was taken from Kintch et al. The reading times of target sentences from coherent explicit and incoherent implicit versions of a text about biology were measured. Finally, we looked at whether adding questions during reading facilitates text comprehension and memorization. Our second hypothesis was that adding questions increases the reading time of the target sentence.
Finally, our fourth hypothesis predicted an causal in a sentence between expertise and presence of connective on sentence reading times and performance. So the difference on reading times and on performance between the two groups should be greater with connective than without connective because experts possess a richer causally- related knowledge network about biology phenomena than novices.
It contained 44 sentences divided into 8 paragraphs, four in the explicit version and four in the implicit version. Paragraphs in explicit versions contained 6 sentences and an average of words; paragraphs in implicit versions contain 5 sentences and an average of 83 words. Text is presented in Appendix. The causal-inference sentence was present in explicit versions and absent in implicit ones. The supplementary inference sentences were taken from a pilot study in which 18 experts biology teachers and experts others than those who participated in the experimental study were asked to give the cause of the consequence described in the target sentences of the implicit versions of the paragraphs.
So the causal supplementary sentence conveyed relevant information about the paragraph topic in which effect meaning in tamil language was inserted and provided causally- pertinent knowledge for the consequence information in the target sentence. So in this example, the target sentence was:. Each causal in a sentence list was presented for times to each group of participants.
They were informed that they had to answer two questions at the end of four paragraphs. The questions were inserted to ensure accurate text comprehension. The situation model questions causal in a sentence about the content of the supplementary inference sentences in kenapa cannot connect to app store explicit versions, which had been elaborated in the pilot study.
So both types of questions were asked in half of the paragraphs, i. Pressing the space bar after reading a sentence erased the current sentence and displayed the next one. The form of these questions was the same as those presented during reading. Fill in the missing word:. Participants were asked to write down their answers, with no time limit.
The answers were scored by the experimenters. In the case of text-based questions, the score was either 0 no answer or wrong answer or 1 word same as or similar to the one in the text. In the case of mental model questions, the scores scale had the following possible scores: 0. Causal in a sentence highest score 1 was given when the answer expressed the idea described in the causal inference sentences of the explicit versions.
Similar results have been observed when these reading times were divided by the number of words of target sentences. The means were ms and ms for novices, and ms and ms for experts, respectively. Means reading time in ms as a function of version, expertise, and the presence of questions. But in conditions without questions, there was no significant difference between explicit and implicit versions ms and ms.
So, novices read target sentences longer only in the implicit condition with questions. So, these readers had a more homogeneous pattern of reading times. Although the interaction between expertise and presence of connective was not significant Hypothesis 4the superiority of reading times of experts, compared to novices, was greater with the connective more ms than without the connective more ms.
This result suggests that experts, in the presence of connective, try more actively than novices to comprehend the causal relation of the target sentence. The results confirmed this prediction: subjects took more time to read sentences except target sentences associated with questions than sentences without questions 35 ms vs. By contrast, novices took more time to read sentences associated with questions than ones without questions 35 ms vs.
Experts, on the other hand, tended to read in a more homogeneous way, regardless of the presence or absence causal in a sentence questions at the end of paragraph. Table 2 presents the mean percent of correct responses as a function of expertise, version, and connective presence during reading. Mean percent of correct responses as a function of expertise, connective presence, and version during reading.
Correct responses for situation-model questions were less frequent than for text-based questions. Explicit versions led to better performance than implicit ones. Text-based responses were state the ph ranges of acids and bases in the two versions.
However, situation-model responses were more frequent in explicit versions than in implicit ones. By contrast, the situation-model answers were always absent in the implicit versions, so readers had to infer them, which is a more difficult task. In the explicit versions, the connective tended to improve performance with the connective. There was no interaction between expertise and type of response text-based or situation modelnor between expertise and type of version explicit or implicit.
Experts outperformed novices for all questions pooled sum of correct text-based and situation-model responses:. Correct causal in a sentence responses were less frequent than were correct text-based responses. These results are similar to those observed during reading and show once again, on this delayed task, that it was difficult to infer information in the implicit versions. As during text reading, there was no interaction between expertise and type of response text-based or situation-modelnor between expertise and type of version explicit vs.
This suggests that compared to novices, experts know how to make better use of their reading time to understand text information, given that the target reading times of the two groups were equivalent. Probably, readers tried to process target sentences more deeply when they knew they had to answer questions and when the connective indicated a cause-consequence relationship between the target sentence and the sentence that causal in a sentence it. Novices increased their reading time in the implicit versions but only when they had to causal in a sentence questions.
Because the implicit versions were locally non coherent, the novices were probably sensitive to the textbase and particularly to the absence of arguments and concepts shared by the target sentence and the sentence before it. Novices also had higher paragraph reading times when they were informed that a question would be asked at the end of the paragraph.
By contrast, experts appeared to process the textual information in a more homogeneous manner. However, they read in a more effective and adapted way; their reading times correlated with their performance, contrary to novices. So experts and novices appear to adopt different strategies for reading and processing textual information.
Kintsch et al. For example, unlike novices, they appeared to be more interested in the implicit version of expository text than in the explicit version. However experts were more sensible than novices to the causal connective; indeed their superiority in reading times —compared to novices — appeared especially in reading target sentences associated with the connective. This result is classic in the literature and is interpreted to mean that situation-model representations are more difficult to elaborate than textbase ones: the former are based on a text comprehension process whereas later require text memorization.
However, no interaction was observed between expertise and the type of question, nor between expertise and connective. This result suggests that experts did not differ from novices in questions related to the situation model. Biology students probably do not have accurate knowledge of the evolution of living organisms. Most of the biology students on this study were beginning their university biology studies.
Causal in a sentence is possible that causal in a sentence general familiarity facilitated text comprehension among the experts. In the same vein, McNamara showed that both high and low biology- knowledge subjects can use logic and common sense ideas to facilitate scientific text comprehension. It is possible that our readers, especially the experts, used this type of knowledge to improve text comprehension and recall.
Indeed, the interaction between questions and versions during reading showed that there was no difference in the recall of answers related to the textbase, no matter what version was at stake. This is due to the fact that this type of answer was always written in the target sentence, in both versions. By contrast, causal in a sentence number of correct responses related to the situation model was much lower in the implicit versions than in the explicit ones.
The reason for this is that in implicit versions, readers had examples of producers and consumers in economics infer the correct answer which is not written in the text and in love is so bad lyrics cases, they probably did not possess the correct information, not even the experts.
In explicit versions, however, readers in both groups took advantage of the presence causal in a sentence inference information. In this case, the correct information had to be searched for in long-term memory. It is possible that, because the target-sentence reading times were longer in implicit versions than in explicit ones, this type of information the word that belonged to what is the definition of symmetric target sentence was read for a longer time and processed better.
So, this information was recalled better than the same information in explicit versions.
