Many studies have demonstrated that illustrating expository science texts with images that are interesting, but irrelevant for understanding the causal relations underlying scientific phenomena, can cause seduction effects, which can reduce understanding from text. The term “seduction effects” refers to the influence that images are thought to have on readers, seducing them away from deeply processing important information. The present study explores whether images relevant for instructional goals may also show some seduction effects. In this study, the presence of photographic images negatively impacted understanding compared with the presence of relevant animations or instructing students to sketch a drawing during reading. However, the results showed that both photographic images and relevant animations could lead to illusions of understanding, whereas sketching did not. The results suggest that even images that are relevant for instructional goals may sometimes result in seduction effects that deceive readers when judging their own understanding. 相似文献

Sudden comprehension—or insight—during problem-solving can enhance learning, but the underlying neural processes are largely unknown. We investigated neural correlates of learning from sudden comprehension using functional magnetic resonance imaging and a verbal problem-solving task. Solutions and “solutions” to solvable and unsolvable verbal problems, respectively, were presented to induce sudden comprehension or continued incomprehension. We found activations of the hippocampus, medial prefrontal cortex (mPFC), amygdala, and striatum during sudden comprehension. Notably, however, mPFC and temporo-parietal neocortical structures rather than the hippocampus were associated with later learning of suddenly comprehended solutions. Moreover, difficult compared to easy sudden comprehension elicited midbrain activations and was associated with successful learning, pointing to learning via intrinsic reward. Sudden comprehension of novel semantic associations may constitute a special case of long-term memory formation primarily mediated by the mPFC, expanding our knowledge of its role in prior-knowledge-dependent memory. 相似文献

Subjective cognitive decline (SCD) might represent the preclinical phase of Alzheimer’s disease. Given the interest to characterize it, the present study explores (1) if there are differences in lexical retrieval (LexR) and sentence comprehension (SComp) between SCD and matched controls, and (2) the predictive value of demographic variables and executive functions in relation to LexR and SComp in each group. A sample of 135 participants voluntarily took part in this study (66 with SCD). They all completed the Trail Making, the Stroop, the Boston Naming, and the ECCO-Senior tests, as well as verbal fluency tasks (VF). Results show that (1) groups differ in LexR and in inhibition efficiency, and (2) VF is explained by years of formal education, particularly in the control group; SComp in the most complex items seems to rely in different strategies, related to flexibility in controls and to inhibition efficiency in SCD patients. 相似文献

It has been shown that when two arrays of Arabic numerals were briefly presented, observers could accurately indicate which array contained the larger number of a target numeral. This study investigated whether this rapid proportion comparison can be extended to other meaningful symbols that share some of notable properties of Arabic numerals. We tested mainly several Japanese Kanji letters, each of which represents a meaning and can work as a word. Using physically identical stimulus sets that could be interpreted as different types of letters, Experiment 1 first confirmed the rapid proportion comparison with Arabic numerals for Japanese participants. Experiment 2 showed that the rapid proportion comparison can be extended to Kanji numerals. Experiment 3 successfully demonstrated that rapid proportion judgments can be found with non-quantitative Kanji letters that are used frequently. Experiment 4 further demonstrated the rapid proportion comparison with frequently used meaningful non-letter symbols (gender icons). The rapid processing cannot be attributed to fluent processing of familiar items, because it was not found with familiar phonograms (Japanese Kana letters). These findings suggest that the rapid proportion comparison can be commonly found with frequently used meaningful symbols, even though their meaning is not relevant to the task. 相似文献

Two eye-tracking experiments were conducted to compare the online reading and offline comprehension of main verb/reduced relative garden-path sentences and local coherence sentences. Rereading of early material in garden-path reduced relatives should be revisionary, aimed at reanalysing an earlier misparse; however, rereading of early material in a local coherence reduced relative need only be confirmatory, as the original parse of the earlier portion of these sentences is ultimately correct. Results of online and offline measures showed that local coherence structures elicited signals of reading disruption that arose earlier and lasted longer, and local coherence comprehension was also better than garden path comprehension. Few rereading measures in either sentence type were predicted by structural features of these sentences, nor was rereading related to comprehension accuracy, which was extremely low overall. Results are discussed with respect to selective reanalysis and good-enough processing. 相似文献

How do people stretch their understanding of magnitude from the experiential range to the very large quantities and ranges important in science, geopolitics, and mathematics? This paper empirically evaluates how and whether people make use of numerical categories when estimating relative magnitudes of numbers across many orders of magnitude. We hypothesize that people use scale words—thousand, million, billion—to carve the large number line into categories, stretching linear responses across items within each category. If so, discontinuities in position and response time are expected near the boundaries between categories. In contrast to previous work (Landy, Silbert, & Goldin, 2013) that suggested only that a minority of college undergraduates employed categorical boundaries, we find that discontinuities near category boundaries occur in most or all participants, but that accurate and inaccurate participants respond in opposite ways to category boundaries. Accurate participants highlight contrasts within a category, whereas inaccurate participants adjust their responses toward category centers. 相似文献

We have recently argued that unconscious numerical stimuli might activate responses by a match with prespecified action trigger codes (action trigger account) rather than by semantic prime processing (elaborate processing account). [Van Opstal, F., Reynvoet, B., and Verguts, T. (2005). How to trigger elaborate processing? A comment on Kunde, Kiesel, and Hoffmann (2003). Cognition] replicate one piece of evidence for our inference—an inefficiency of primes not presented in target format (verbal or Arabic). But this was found only with letter masks and not with hash masks. The authors conclude that letter masks block unconscious prime processing, and that elaborate processing can account for unconscious priming effects if all its (sometimes subtle) side conditions are considered. We agree that the type of mask in general is an important factor in priming studies but we note that (i) the authors' mask-blocking hypothesis is not well supported by the data, (ii) clear evidence for semantic prime processing in their study is lacking and, (iii) differences in mask efficiency (rather than mask type) might account for the conflicting results. To corroborate this inference we replicate van Opstal et al.'s results with letter masks but reduced mask efficiency. Altogether their data do not challenge the action-trigger account nor do they strongly support the elaborate processing view. 相似文献

该研究考察了非英语专业具有不同英语语言水平学习者在不同难度条件下两种文化特征熟悉度对阅读理解的影响。研究发现:(1)语言水平高,或对材料背景熟悉的学习者可通过调用熟悉的文化背景知识帮助阅读理解,其得分均高于低水平,或对材料不熟悉的学习者;(2)在熟悉的文化背景条件下,当材料难度与学习者语言水平基本一致时,语言水平低的学习者也可较好地运用熟悉的文化背景知识帮助阅读理解。实验结果表明:文化特征的内容熟悉度和英语语言水平(或文章难度)对阅读理解起着重要作用,语言水平越高,作用越大。 相似文献
