Choices and opportunities: another effect of framing on decisions

Many decisions can be framed either as ‘choices’ between alternative courses of action (e.g. Should I move to New York or stay in Chicago?) or as ‘opportunities’ to pursue a particular course of action (i.e. Should I move to New York?). Although there is no logical difference between these two different decision frames, there may be important psychological differences between them. In four studies, we explore the differences between ‘choices’ and ‘opportunities’. The results of Studies 1 and 2 show that college students view many of the decisions they typically face as opportunities, rather than choices. Further, the results of Study 2 suggest that the frame students adopt is systematically related to the preferences they express. The latter finding led to Studies 3 and 4, where we show that preferences can be influenced by encouraging people to adopt one decision frame rather than another. © 1998 John Wiley & Sons, Ltd.     

Prospective effects of interparental conflict on child attachment security and the moderating role of parents' romantic attachment.

This study investigated the impact of parents' observed conflict behavior on subsequent child attachment security, both as a main effect and as moderated by parents' romantic attachment. Participants were 80 heterosexual couples involving men from the Oregon Youth Study and their first-born children. The authors used hierarchical linear modeling to predict child security with each parent. Interparental psychological aggression predicted lower child security with father, regardless of romantic attachment. If the father was insecure, interparental positive engagement predicted lower child security with him. If either the mother or father was avoidant, interparental withdrawal did not predict lower child security, though it did for more secure parents. Results are discussed in terms of implications of attachment-(in)congruent behavior for parents' emotional availability.     

Concurrent working memory load can facilitate selective attention: evidence for specialized load

Load theory predicts that concurrent working memory load impairs selective attention and increases distractor interference (N. Lavie, A. Hirst, J. W. de Fockert, & E. Viding). Here, the authors present new evidence that the type of concurrent working memory load determines whether load impairs selective attention or not. Working memory load was paired with a same/different matching task that required focusing on targets while ignoring distractors. When working memory items shared the same limited-capacity processing mechanisms with targets in the matching task, distractor interference increased. However, when working memory items shared processing with distractors in the matching task, distractor interference decreased, facilitating target selection. A specialized load account is proposed to describe the dissociable effects of working memory load on selective processing depending on whether the load overlaps with targets or with distractors.     

东西方医学伦理思维之共通性

从中国古代医者的行医事迹、著作来探寻中国的医者是否在行医过程当中勤守医者的本份,也即类似原则思维的表现。虽然中国古代并没有"医学伦理"这个名词,但从历代具有代表性之医者身上发现,其实在中国古代医者的行医事迹当中,就表现出类似的医学伦理情操。因之,医学伦理原则是俱普世价值的,也即世界上有所谓的共同道德存在。     

Filiality,Compassion, and Confucian Democracy

Ren, the Confucian virtue par excellence, is often explained on two different accounts: on the one hand, filiality, a uniquely Confucian social-relational virtue; on the other hand, commiseration innate in human nature. Accordingly there are two competing positions in interpreting ren: one that is utterly positive about the realization of universal love by the graduated extension of filial love, and the other that sees the inevitable tension between the particularism of filial love and the universalism of compassionate love and champions the latter in that filial love appears to create a serious obstacle to modernizing Confucianism. Nevertheless, both interpretations agree that compassion, given its universal and humanist implications, can be unquestionably conducive to the modern project of ‘Confucian democracy’. This paper counters this shared view by arguing that in order to make Confucian democracy culturally meaningful and politically viable, it must accommodate uniquely Confucian relational virtues, particularly filiality.     

Prefrontal cortex and hippocampus subserve different components of working memory in rats

Both the medial prefrontal cortex (mPFC) and hippocampus are implicated in working memory tasks in rodents. Specifically, it has been hypothesized that the mPFC is primarily engaged in the temporary storage and processing of information lasting from a subsecond to several seconds, while the hippocampal function becomes more critical as the working memory demand extends into longer temporal scales. Although these structures may be engaged in a temporally separable manner, the extent of their contributions in the "informational content" of working memory remains unclear. To investigate this issue, the mPFC and dorsal hippocampus (dHPC) were temporarily inactivated via targeted infusions of the GABA(A) receptor agonist muscimol in rats prior to their performance on a delayed alternation task (DAT), employing an automated figure-eight maze that required the animals to make alternating arm choice responses after 3-, 30-, and 60-sec delays for water reward. We report that inactivation of either the mPFC or dHPC significantly reduced DAT at all delay intervals tested. However, there were key qualitative differences in the behavioral effects. Specifically, mPFC inactivation selectively impaired working memory (i.e., arm choice accuracy) without altering reference memory (i.e., the maze task rule) and arm choice response latencies. In contrast, dHPC inactivation increased both reference memory errors and arm choice response latencies. Moreover, dHPC, but not mPFC, inactivation increased the incidence of successive working memory errors. These results suggest that while both the mPFC and hippocampus are necessarily involved in DAT, they seem to process different informational components associated with the memory task.     

Regulation of Teacher Elicitations in the Mathematics Classroom

Using the perspective of instructional conversation, we investigated how one teacher regulated student participation and conceptual reasoning in the middle-school mathematics classroom. We examined the elicitations—questions and provocative statements—made by the teacher over a four-day algebra lesson. Analyses showed how the teacher systematically regulated the level of cognitive complexity of his elicitations in reaction to students' responses. When students gave inaccurate or incomplete answers, the teacher tended to reduce the level of cognitive complexity needed to respond to a subsequent elicitation, with the apparent impact being that he scaffolded participation and reasoning. When students provided responses that were mathematically accurate, the teacher usually increased the elicitation level, which subsequently engaged students in more sophisticated forms of reasoning.     

Attachment and relationship satisfaction in expectant first-time parents: The mediating role of relationship enhancing behaviors

Individual differences in attachment are well established as a correlate of couple relationship satisfaction. However, less is known about the role of attachment in predicting satisfaction at specific milestone points in couple relationships. The present study explored the role of attachment in predicting relationship satisfaction during couples’ first pregnancy, and the mediating role of relationship enhancing behaviors. Male and female attachment anxiety and avoidance predicted their own low relationship satisfaction, and this was partially mediated by relationship enhancing behaviors. Male attachment anxiety and avoidance predicted low female satisfaction, and this was fully mediated by relationship enhancing behaviors. This study is the first to highlight the important role of male attachment during pregnancy, and the mediating role of relationship enhancing behaviors.
