文本表述和结构对小学生数学应用题表征的影响

以450名小学生为被试,探讨了文本表述和结构对小学生数学应用题表征成绩的影响。采用2(难度)×2(题材熟悉度)×5(措辞类型)×3(年级)四因素混合设计。结果表明:不同文本表述和结构对小学生解决数学应用题的影响不因年级的不同而不同;概念性措辞问题和情境性措辞问题都促进了小学生数学应用题的表征成绩;在容易问题中,额外信息对表征成绩影响较大;在较难问题中,数学运算关系难度对表征成绩影响较大;当解决文本背景较简单的标准措辞问题时,题材熟悉度对小学生的理解产生较大影响;文本长度对问题解决的影响取决于所增加的文本是否对理解问题的句法关系和语义情景有益。     

Testing the shared resource assumption in theories of text processing

Eight experiments evaluated a core assumption of several theories of text processing, the shared resource assumption, which states that component text processes share limited processing resources. Short texts each contained two critical sentences that together warranted a causal inference. The syntactic structure of the second sentence was either more or less difficult to parse. Results from a lexical decision task suggested that readers formed the causal inferences when the syntactic structure was less difficult to parse but that inferencing was constrained when syntactic structure was more difficult. Follow-up experiments suggested that this interference was not due to inferior output of the syntactic parser nor to the increased demands of difficult syntax interfering with maintenance of information needed to form the inference. The results suggest insufficient resources were available for the operation of inference processes due to the increased demands of syntactic parsing, consistent with the shared resource assumption.     

CoTO: A novel approach for fuzzy aggregation of semantic similarity measures

Semantic similarity measurement aims to determine the likeness between two text expressions that use different lexicographies for representing the same real object or idea. There are a lot of semantic similarity measures for addressing this problem. However, the best results have been achieved when aggregating a number of simple similarity measures. This means that after the various similarity values have been calculated, the overall similarity for a pair of text expressions is computed using an aggregation function of these individual semantic similarity values. This aggregation is often computed by means of statistical functions. In this work, we present CoTO (Consensus or Trade-Off) a solution based on fuzzy logic that is able to outperform these traditional approaches.     

The Role of Psychology in Media During the COVID-19 Pandemic: A Cross-National Study

Dealing with COVID-19 and with the preventative measures that have been taken to mitigate the transmission of the virus causing the pandemic has posed a great challenge to the population. While psychologists have expertise with regard to preventive behavior change and to dealing with the mental health impact of measures, their expertise needs to be effectively communicated to the public. Mass media play a critical role in times of crisis, in many cases being the only source of information. While most research focuses on the importance of information content as a factor affecting psychological responses to a collective traumatic event, the way information is framed in the media is likely to influence the way health professionals are perceived as trustworthy. This study aimed to analyze the media framing of information from psychology during the COVID-19 pandemic in six countries from America and Europe, identifying the most recurrent topics in the news (n news items = 541) related to psychology and mental health. In all six countries the media address the psychological needs of the population, which vary depending on the imposed restrictions. The news content is influenced by the scientific sources used by the media. While the most prevalent topics focus on psychological risk and the need to seek mental health care, the least prevalent topics relate to counseling and behavioral guidelines for managing the psychological consequences of the pandemic. The study findings provide insight into how psychological knowledge contributes to the understanding and mitigation of COVID-19 consequences in different countries and identified fields where psychologists were consulted to respond to a health emergency. They also show a preference to consult other experts when searching for contextual or more macro-social explanations of critical situation.     

Negative priming and sequence learning

Three experiments used a novel sequence learning task, in which participants responded to changes in location of one visual stimulus whilst ignoring another. Experiment 1 demonstrated negative priming effects in this task, in that responses to individual sequence elements were disrupted when the attended stimulus (e.g., red asterisk) appeared at the location taken by the unattended stimulus (e.g., blue asterisk) on the immediately preceding trial. Experiments 2 and 3 found that negative priming effects extended beyond sensitivity to individual items, suggesting that people may be able to learn about sequential features of ignored events as well as about single events in isolation. The results are discussed in relation to current theories of negative priming.     

Behavioral and fMRI evidence that cognitive ability modulates the effect of semantic context on speech intelligibility

Text cues facilitate the perception of spoken sentences to which they are semantically related (Zekveld, Rudner, et al., 2011). In this study, semantically related and unrelated cues preceding sentences evoked more activation in middle temporal gyrus (MTG) and inferior frontal gyrus (IFG) than nonword cues, regardless of acoustic quality (speech in noise or speech in quiet). Larger verbal working memory (WM) capacity (reading span) was associated with greater intelligibility benefit obtained from related cues, with less speech-related activation in the left superior temporal gyrus and left anterior IFG, and with more activation in right medial frontal cortex for related versus unrelated cues. Better ability to comprehend masked text was associated with greater ability to disregard unrelated cues, and with more activation in left angular gyrus (AG). We conclude that individual differences in cognitive abilities are related to activation in a speech-sensitive network including left MTG, IFG and AG during cued speech perception.     

Moral chronicity and social information processing: Tests of a social cognitive approach to the moral personality

Following Higgins, King, and Mavin (1982) chronicity paradigm, we examined the effects of chronically accessed moral constructs for prototypic moral character using two different research paradigms, spontaneous trait inferencing and lexical decision. Study 1 presented target sentences in a deliberate or spontaneous processing condition. Recall was cued with either a dispositional or semantic cue. Moral chronics made more spontaneous trait inferences with dispositional cues than semantic cues. In Study 2, participants read stories about characters who did or did not help. Moral chronics were faster responding to probes reflecting negative evaluations of story characters who did not help when requested (e.g., “disloyal”). Findings support claims that the moral personality is usefully conceptualized in terms of the chronic accessibility of moral knowledge structures.     

论《易纬》对《周易》经传的阐释

纬书是相对经书而言的,因此,纬书中有很多内容是阐发和解释经书的。《易纬》是纬书的一种,对《周易》经传阐发和解释也是《易纬》的一个重要内容。在内容阐发上,其对《周易》的起源、作者以及乾坤二卦和象数等方面提出了与众不同的看法;在经文解释上,其对《周易》的经文作了直接的解释。由此我们可以看出《易纬》与汉代其它易学学派不同的易学观。     

Influence of suggestion in the DRM paradigm: what state of consciousness is associated with false memory?

We assessed the effect of suggestion on the Deese–Roediger–McDermott paradigm and associated it with the Remember–Know–Guess paradigm. Undergraduate students were given either lists of semantically related words or texts containing these words. After the recall task, if participants did not produce the critical lure, the experimenter suggested that the word had been present, using either a question (moderate suggestion) or an assertion (strong suggestion); these conditions were compared to a condition without suggestion. Afterwards, participants took a recognition test. The results showed that strong suggestions lead to more false recognitions than other conditions and the state of consciousness associated with false recognitions tends to be a feeling of knowing rather than remembering, regardless of the verbal version (list or text). Therefore moderate suggestions did not lead to more false recognitions compare to no suggestion. We discuss the impact of suggestion on consciousness associated with false memories.
