不同学习方式下习得性长时程突触增强形成的特点

一般认为,突触传递的长时程增强(Long-term potentiation,LTP)可能是学习和记忆的神经基础。我室的系列工作表明,大鼠在条件性行为的建立中,海马齿状回、CA_3、CA_1区均出现LTP样变化,并将之称为习得性LTP(Learning-de-pendent LTP),而且发现每次训练作业后突触效应的增强,经一段时间(4小时)后就     

The mood effect: How mood,disclosure language and ad skepticism influence the effectiveness of native advertising

This research investigated the interplay between mood, disclosure language, and ad skepticism on consumers' recognition and evaluation of native advertising. During two online experiments, participants first received a mood manipulation and then read an article-style native advertisement. Results from both studies indicated that participants were more likely to recognize a native ad with an explicit rather than an implicit disclosure label, and a negative mood was more likely than a positive mood to drive participants to recognize the native ad. More importantly, participants in a positive mood evaluated a native ad with an implicit disclosure more favorably than an ad with an explicit disclosure. By contrast, participants in a negative mood responded more positively to a native ad with explicit disclosure compared to an ad with implicit disclosure. Study 2 demonstrated that the interaction between mood and disclosure language was further moderated by individuals' levels of ad skepticism. These results are believed to provide meaningful theoretical and practical implications to the field of native advertising and consumer behavior.     

Grading the ‘cultural literacy’ project

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise.     

Referenzsemantik in der Partnermodellierung

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.
