After the rapid increase of the American divorce rate in the late 20th century, one of the most conspicuous efforts of the marriage movement in the 1990s that was used to increase marital stability was the legislation of the covenant marriage license, a more restricted marriage license issued in three different states of the U.S. To investigate the marital life of newlywed covenant versus standard couples, a large-scale 5-year couple study was conducted between 1998 and 2003 in Louisiana. The present study uses this large-sample, multiple-wave, multiple-group dyadic dataset to examine differences in co-development and divorce rates in 297 covenant and 380 standard mixed-sex couples using a multiple group growth curve modeling and survival analysis. We examined differences in marital trajectories between covenant and standard couples as well as between husbands and wives in each marital group. The results show (1) that the couples in both groups experienced, on average, declines in marital satisfaction, and such a decline was slower in covenant husbands than their wives as well as those in standard marriages, and (2) that co-development in marital satisfaction was more prominent in standard marriages than in covenant marriages, meaning standard couple's marital satisfaction declined at a more similar rate than that of covenant couples. We provide possible explanations and discuss practical implications. 相似文献

It was previously demonstrated in our laboratory that conditioned fear in humans can renew after extinction, when this procedure took place in a different context (ABA-renewal [Vansteenwegen et al. (2005). Return of fear in a human differential conditioning paradigm caused by a return to the original acquisition context. Behaviour Research and Therapy, 43(3), 323–336]). Using the same experimental design, we now tested the power of retrieval cues to interact with this contextual renewal phenomenon. Two groups went through acquisition and extinction (in a different context). They were then tested in the original acquisition context and in the presence of a retrieval cue. In the acquisition-cue group, this cue previously featured during the acquisition procedure; in the extinction-cue group, the cue previously featured during the extinction procedure. As expected, renewal of conditioned electro-dermal responding and retrospective expectancy ratings was strongest in the acquisition-cue group. Theoretical and clinical implications of this finding are discussed. 相似文献

This study examined the effect of overt head movement on attitudes toward a product. In a headphones test, participants were required to listen to music and to either nod or shake their heads. Some participants listened to a CD of music; other participants listened to a CD of the same music and a persuasive message about the headphones. Overt head movement affected participants' product choice and price perception when they were presented with the music and a persuasive message. The findings are interpreted to suggest that head movement can be instrumental in participants' product evaluation if the head movement is directed or focused on the attitude object. 相似文献

Based on terror management theory, the authors suggest that ambivalent reactions to the human body are partially rooted in the association of the physical body with inescapable death and that individuals high in neuroticism are particularly vulnerable to such difficulties. Three experiments demonstrated that priming thoughts about one's death leads individuals high in neuroticism to flee from physical sensations, including pleasurable ones. In response to mortality salience, highly neurotic individuals spent less time submerging their arm in ice-cold water and using an electric foot massager but did not avoid stimulation in nontactile modalities (i.e., listening to music). The discussion highlights the role of existentially motivated self-repression in inhibitions surrounding the body. 相似文献

Changes in the parental bond and the well-being of adolescents and young adults were investigated in this longitudinal study among Dutch youngsters aged 12 to 24 years (their ages ranged from 15 to 27 years when they were assessed for the second time three years later, and from 18 to 30 years when assessed for the third time). A total of 1,078 adolescents/young adults (459 males and 619 females) participated. We found a curvilinear pattern in the bond between daughters and their parents. For most of the boys, there was a deterioration in the parental bond during the transition from early to midadolescence, which does not subsequently improve. The general conclusion, however, is that adolescents and young adults maintain a rather good and reasonably stable relationship with their parents. Parents prove to be of lasting importance for the well-being of their growing children. For adult children, the parental bond appears to be as important for their well-being as having a partner or a best friend. 相似文献

We investigate whether two-digit numbers are decomposed for purposes of numerical comparison (e.g., choosing the larger one). Earlier theorists concluded that numbers are processed holistically (Brysbaert, 1995; Dehaene, Dupoux, & Mehler, 1990), or that holistic and decomposed processes operate in parallel (Nuerk, Weger, & Willmes, 2001). In the present experiment, we presented pairs of two-digit numbers with a decade distance of either zero (e.g., 54-57) or one (54-61). If a holistic process contributes to two-digit comparison, there should be an overall distance effect for number pairs with a decade distance of one. On the other hand, if numbers are decomposed and a holistic comparison does not contribute, this overall distance effect should be absent for these number pairs. Evidence is found that, at least in the present task settings, numbers are not compared holistically. The results are interpreted in terms of a recently proposed theory of numerical cognition (Verguts & Fias, 2004; Verguts, Fias, & Stevens, in press). 相似文献

In a contingency learning task, 4-year-old and 8-year-old children had to predict the outcome displayed on the back of a card on the basis of cues presented on the front. The task was embedded in either a causal or a merely predictive scenario. Within this task, either a forward blocking or a backward blocking procedure was implemented. Blocking occurred in the causal but not in the predictive scenario. Moreover, blocking was affected by the scenario to the same extent in both age groups. The pattern of results was similar for forward and backward blocking. These results suggest that even young children are sensitive to the causal structure of a contingency learning task and that the occurrence of blocking in such a task defies an explanation in terms of associative learning theory. 相似文献

Embodiment has become the raison d’etre for much of the new ‘cognitive robotics’. It fills a gap in the non-interactivist approach of traditional artificial intelligence (AI) in which ‘intelligence’ is viewed as the manipulation of symbols in a vacuum. However, a foundational question for the new AI is, can embodiment lead to a strong AI, i.e. a robot mind? To address this question, two extreme poles of embodiment are distinguished here, mechanistic and phenomenal. A detailed exploration of each type of embodiment is provided together with an appraisal of whether strong embodiment is possible for robotics, or whether robotics merely provides a tool for scientific exploration and modelling, i.e. weak embodiment? It is argued that strong embodiment, either mechanistic or phenomenal, is not possible for present day robots. However, weak embodiment may provide an enlightened approach to using robots for modelling cognition. 相似文献

Multiple regression quadratic assignment procedures (MRQAP) tests are permutation tests for multiple linear regression model
coefficients for data organized in square matrices of relatedness among n objects. Such a data structure is typical in social network studies, where variables indicate some type of relation between
a given set of actors. We present a new permutation method (called “double semi-partialing”, or DSP) that complements the
family of extant approaches to MRQAP tests. We assess the statistical bias (type I error rate) and statistical power of the
set of five methods, including DSP, across a variety of conditions of network autocorrelation, of spuriousness (size of confounder
effect), and of skewness in the data. These conditions are explored across three assumed data distributions: normal, gamma,
and negative binomial. We find that the Freedman–Lane method and the DSP method are the most robust against a wide array of
these conditions. We also find that all five methods perform better if the test statistic is pivotal. Finally, we find limitations
of usefulness for MRQAP tests: All tests degrade under simultaneous conditions of extreme skewness and high spuriousness for
gamma and negative binomial distributions.
