冲动性特质对高中生自杀意念的影响:校园排斥与生命意义感的作用

采用冲动性特质量表、青少年遭受校园排斥问卷、生命意义感量表、自杀意念量表对633名高中生进行调查。结果表明:(1)冲动性特质对高中生自杀意念有显著的正向预测作用;(2)校园排斥在冲动性特质与高中生自杀意念间起部分中介作用;(3)冲动性特质经由校园排斥影响高中生自杀意念的中介作用受生命意义感的调节,随着生命意义感的增加,校园排斥对自杀意念的效应逐步减弱。冲动性特质可以通过校园排斥增加高中生自杀意念强度,而生命意义感能有效降低校园排斥对自杀意念的消极影响。     

Effects of Personalized Banner Ads on Visual Attention and Recognition Memory

Internet companies collect a vast amount of data about their users in order to personalize banner ads. However, very little is known about the effects of personalized banners on attention and memory. In the present study, 48 subjects performed search tasks on web pages containing personalized or nonpersonalized banners. Overt attention was measured by an eye‐tracker, and recognition of banner and task‐relevant information was subsequently examined. The entropy of fixations served as a measure for the overall exploration of web pages. Results confirm the hypotheses that personalization enhances recognition for the content of banners while the effect on attention was weaker and partially nonsignificant. In contrast, overall exploration of web pages and recognition of task‐relevant information was not influenced. The temporal course of fixations revealed that visual exploration of banners typically proceeds from the picture to the logo and finally to the slogan. We discuss theoretical and practical implications. Copyright © 2014 John Wiley & Sons, Ltd.

The brain generates its own sentence melody: a Gestalt phenomenon in speech perception

Brain processes underlying spoken language comprehension comprise auditory encoding, prosodic analysis and linguistic evaluation. Auditory encoding usually activates both hemispheres while language-specific stages are lateralized: analysis of prosodic cues are right-lateralized while linguistic evaluation is left-lateralized. Here, we investigated to what extent the absence of prosodic information influences lateralization. MEG brain-responses indicated that syntactic violations lead to early bi-lateral brain responses for syntax violations. When the pitch of sentences was flattened to diminish prosodic cues, the brain's syntax response was lateralized to the right hemisphere, indicating that the missing pitch was generated automatically by the brain when it was absent. This represents a Gestalt phenomenon, since we perceive more than is actually presented.     

Is There Such a Thing as Relative Analyticity?

Fine bases his influential conception of essence on a particular account of definitions. And he complements it with a specific account of analyticity. I will argue that Fine's conception of relative analyticity confuses the idea of a sentence's being true in virtue of a term's definition with the idea of a sentence's being true in virtue of a term's meaning. His idea that correct definitions specify essential properties of meanings is mistaken. The correctness of definitions can only be assessed by reference to the actual usage of the terms involved. The resulting conception of definitions leads to a deflationary interpretation of claims about essences.
