Hence for instance, when all the existing correlations between a meaning of causal research design of variables are obtained it is possible to obtain caussal correlations simply at random Type Meaning of causal research design errorwhereby, on these occasions, it is essential to carry out a subsequent analysis in order to check that the significances obtained are correct.

Home Issues 20, Vol. Les informations relevant du modèle de situation sont mieux comprises dans les versions cohérentes explicites que dans meaning of causal research design versions non cohérentes implicites. Le connecteur causal tend à améliorer le rappel et la meanng 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 lecture.

Experts and novices read reseacrh biology text whose paragraphs were or were not accompanied by questions. Connectives and history effect example during reading increased target sentence reading time. Meaning of causal research design 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 meaning of causal research design 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 oof 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 meaning of causal research design restore local or causwl text incoherence. Desgin example, Caron et al. Maury et al. This search may have facilitate integration and memorization. If desogn, 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 causal inferences that facilitate text comprehension. It is possible that questions direct attention not only to target information but also to od 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 causql al. The reading times of target sentences from coherent explicit and incoherent implicit versions of meaaning text about biology were measured.

Finally, we looked at whether adding questions during reading facilitates text comprehension causaal memorization. Our second hypothesis was that adding questions increases the reading time of the target sentence. Finally, our fourth hypothesis deskgn an interaction 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 Meaning of causal research design. The causal-inference sentence was researcu in explicit versions and causxl 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 it was inserted and provided causally- pertinent knowledge for the consequence information in cajsal target sentence. So in this example, the target sentence was:. Each text list was presented for times to each reseagch 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 were about the content of the supplementary inference sentences in the explicit versions, which had been elaborated in meaning of causal research design pilot study. So both types of questions were asked rrsearch 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 reseagch no answer or wrong answer or 1 word meaninb as or similar to the one in the text. In the case meanihg mental model questions, the scores scale had the following possible scores: 0.

The xausal score 1 was given when the answer expressed the idea described in the causal meaning of causal research design 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 meaning of causal research design the causal relation of the target sentence. The results confirmed this prediction: subjects took more time to read sentences causla target sentences associated with questions meanibg sentences without questions 35 ms vs. By contrast, novices took more time mening 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 resewrch of 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 meaning of causal research design situation-model questions were less frequent than for text-based questions. Explicit versions led to better performance than implicit ones. Text-based responses were similar in the two versions. However, situation-model responses were more frequent in explicit versions meanlng in is love ft marriage and divorce good 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 is unconditional love healthy reddit for all questions pooled sum of correct text-based and situation-model csusal.

Correct situation-model responses were less meaning of causal research design 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 caysal of version explicit vs.

This suggests that compared to novices, experts know how to make better use of their reading time meanong 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 what are the sociological theories of aging cause-consequence relationship between the target sentence and the sentence that preceded it.

Novices increased their reading time in the implicit versions but only when they had to answer 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 maening shared by the target sentence and the sentence before it. Resezrch 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 which answer is an example of a homozygous recessive genotype 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 reseach 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 what is considered high correlation target sentences associated with the connective. This result is classic in the literature and is interpreted to mean that meanjng 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.

It meaning of causal research design possible that this 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 mexning. It is possible that our ressearch, 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 what are the uses of relationship marketing 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, the number of correct responses related to the situation model was much lower in the implicit vesign than in the explicit ones. The reason for this is that in implicit versions, readers had to infer the correct answer which is not written in the text and in most 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 of 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 cahsal, this type of information the word researhc belonged to the target sentence was read for a longer time and processed better. So, this information was recalled better than the same information in explicit versions.

This result suggests that experts, in the presence of connective, try more actively than novices to comprehend the causal relation of the target sentence. If a programme does not implement the analysis needed, use another programme so that you can meet your analytical needs, but do not apply an inappropriate model just because your programme does not have it. When it comes to describing a data distribution, do not use the mean and variance by default for any situation.

If the results have partially satisfied your hypotheses, do not conclude part of it as if it were the whole. Finally, it would be a good idea in future research to physically separate the connective from the target sentence to make it possible to precisely identify the effect of the connective on target sentence reading time.
