Do we look happy? Perceptions of romantic relationship quality on Facebook

Does the information that people share about their romantic relationships on Facebook influence how other people perceive their relationship quality? Across 2 studies, people's accuracy at inferring others' relationship quality based on their Facebook profiles and how Facebook profiles influenced others' judgments of people's relationship quality and likability were investigated. Perceived relationship quality corresponded to self‐reported relationship quality (Study 1), and people with more visible relationships were perceived as having greater relationship satisfaction and commitment (Studies 1 and 2) and being more likable (Study 2). High disclosure about the relationship predicted greater perceived relationship quality but lower likability (Study 2). These findings illuminate how sharing information about one's relationship influences other people's impressions of the individual and the relationship.     

《周易》对中国古代数学的影响

分析中国古代数学史上重要的数学著作可以看出,《周易》往往被古代数学家们视作数学发展最早的源头,而且在一些重要的数学著作中,数学家们运用《周易》中的有关概念表述数学问题,对《周易》中的数学问题及其相关问题进行深入的研究,取得了重要的数学成就。这一切足以表明《周易》对于古代数学发展具有非常重要的影响。     

INCREASING THE ACCURACY OF CORRECTIONS FOR RANGE RESTRICTION: IMPLICATIONS FOR SELECTION PROCEDURE VALIDITIES AND OTHER RESEARCH RESULTS

The common practice in meta-analyses and in individual studies of correcting for direct range restriction even though range restriction is actually indirect has long been known to lead to undercorrection, but this error has been assumed to be small. Using validity generalization data sets for 4 jobs, this study calibrated this error by comparing meta-analysis results based on corrections for direct range restriction with the more accurate results from a recently developed method of correcting for indirect range restriction. It was found that, on average, correction for direct range restriction resulted in substantial underestimation of operational validities for both job performance measures (21%) and training performance measures (28%). In addition, 90% credibility values were on average underestimated by 38%–40%. In addition to the implications for personnel selection, these findings suggest that similar underestimation of important relationships has occurred in other areas of research, with potential implications for theory development.     

Aesthetics Makes Nothing Happen? The Role of Aesthetic Properties in the Constitution of Non‐aesthetic Value

The relationship between aesthetic value and other moral and cognitive values has been a key theme within contemporary aesthetic discussion. In this article, I explore once again the implications of this relationship, but from what I think might be a different angle. With few exceptions, notably Dominic Lopes, most of the contributions to this issue have dealt with the impact that moral or cognitive values could possibly have on the overall aesthetic value of a work of art. In this article, I explore instead how aesthetic properties or merits could play a role in explaining moral and cognitive properties. To do so, I first offer some examples that I think may reasonably exemplify the phenomenon we are considering. Second, I argue that a proper account of interactionism should meet at least two constraints: the relevance constraint and the autonomy constraint. Finally, I try to clarify how it is possible that aesthetic properties substantially contribute to other values by appealing to the notions of expression and the affective character of aesthetic properties.     

How Do “Religion” and “Spirituality” Differ? Lay Definitions Among Older Adults

Research and public interest in religion and spirituality is on the rise. Consequently, there is an increasing need for rigorously obtained information on what individuals mean when they use these terms. This study examined how 64 older adults living in three retirement communities (including one Christian‐based community), a relatively understudied population, conceptualize religion and spirituality. Participants defined “religion” and “spirituality,” and their narrative definitions were coded and compared using a framework derived from Hill et al.'s (2000) conceptualization of religion and spirituality. Despite considerable overlap, participants' definitions differed on several dimensions. Participants were more likely to associate religion than spirituality with personal beliefs, community affiliation, and organized practices. Moreover, spirituality appeared to be a more abstract concept than religion, and included nontheistic notions of a higher power.     

Attachment and the investment model: Predictors of relationship commitment,maintenance, and persistence

This research examines adult attachment and the investment model. Study 1 tests anxiety and avoidance predicting romantic relationship commitment, mediated by satisfaction, alternatives, and investments. Additional studies added outcomes of relationship maintenance (Study 2) and persistence (Study 3). In all 3 studies, satisfaction, alternatives, and investments mediated the associations between anxiety and avoidance and relationship commitment. A direct effect of avoidance on commitment remained. The investment model variables mediated the effect of anxiety and avoidance on accommodation and willingness to sacrifice (Study 2) and relationship persistence (Study 3). Direct effects remained for avoidance on accommodation and anxiety on persistence. The mediated model was supported for men and women, proximal and long‐distance relationships, and college student and community samples.     

Potency of food deprivation intensity cues as discriminative stimuli.

Rats were trained to use stimuli arising from 0 and 24 hr without food as discriminative signals for shock. In Experiment 1, one group was shocked under 0-hr food deprivation and not shocked under 24-hr food deprivation. Another group received the reverse contingency. The groups received only 3 training trials under each deprivation level. Learning was revealed in a test phase when greater extinction of freezing was observed under the nonshocked than under the shocked deprivation level for both groups. A similar pattern of results was obtained in Experiment 2 when auditory cues were also relevant throughout training. Furthermore, prior training with food deprivation cues seemed to reduce learning about auditory cues subsequently trained in compound with deprivation stimuli. The results indicate that food deprivation intensity cues can be potent discriminative stimuli. The idea that deprivation cues function as conditioned modulatory stimuli cues is also discussed.     

A comparison of the effects of fimbria-fornix, hippocampal, or entorhinal cortex lesions on spatial reference and working memory in rats: short versus long postsurgical recovery period.

Using a radial maze task and different postoperative recovery periods, this experiment assessed and compared the reference and working memory performances of adult Long-Evans male rats subjected to entorhinal cortex, fimbria-fornix, and hippocampus lesions. Sham-operated rats were used as controls. In order to see whether the duration of the postsurgical recovery period would influence acquisition of the complex radial maze task, training began 1 month following surgery (Delay 1) for half the rats in each group, while for the other half training was started 6.5 months following surgery (Delay 2). The results indicated that at both recovery periods the entorhinal cortex lesions failed to affect either working or reference memory in the spatial task. Conversely, both fimbria-fornix and hippocampus lesions impaired both reference and working memory. While the reference memory deficit was generally similar in both fimbria-fornix and hippocampal lesion groups, analysis of the results for working memory indicated that at the longer delay rats with fimbria-fornix lesions were still impaired but in animals that had the hippocampus removed, working memory did not differ from that of controls. These results suggest that there was some recovery in those rats with hippocampal lesions (e.g., on the working memory task) but both hippocampal and fimbria-fornix animals were still impaired compared to controls when training was delayed 6.5 months following the operations.
