This study was designed to investigate the relationship between midlife women's physical activity motives and their participation
in physical activity. Cross-sectional qualitative and quantitative data were collected from 59 midlife women, most of whom
were well-educated European-Americans (mean age = 45.6 years). Body-shape physical activity motives (i.e., motives related
to toning, shaping, and weight loss) were compared with all other types of physical activity motives combined. Participants
with body-shape motives were significantly less physically active than those with non-body-shape motives (p<.01). Negative affect toward physical activity was negatively associated with participation, but did not mediate the effect
of physical activity motives on participation. Body Mass Index (BMI) was not related to physical activity motives or participation.
Results suggest that body-shape motives might be associated with less physical activity participation than non-body-shape
motives among midlife women. 相似文献

A Research Program Testing the Effectiveness of a Preventive Intervention for Couples with a Newborn

Noxious family environments are associated with a wide range of adverse child outcomes. In order to prevent couple and parent–child relationship problems, a number of programs have been developed for couples with newborns. The current paper describes a program of research evaluating the American version of couple CARE for parents of newborns. This version of CCP was administered to low‐income, unmarried couples with a new baby in an uncontrolled demonstration project (Study 1), compared with a waitlist control condition in a randomized controlled trial (Study 2), and evaluated with low‐income parents recruited from urban hospitals in two major metropolitan areas of the United States (Study 3 and Study 4). Despite participant satisfaction with CCP, preventive effects of the program were limited and there was one potential iatrogenic effect. Results were likely impacted by major challenges with recruiting participants and maintaining their engagement in CCP for the duration of the program. We discuss methodological differences between this series of studies and previous trials of prevention programs and make recommendations for improving service delivery to at‐risk new parents. These results have implications for public policies that aim to benefit children and families. 相似文献

The Development of Invariant Object Recognition Requires Visual Experience With Temporally Smooth Objects

How do newborns learn to recognize objects? According to temporal learning models in computational neuroscience, the brain constructs object representations by extracting smoothly changing features from the environment. To date, however, it is unknown whether newborns depend on smoothly changing features to build invariant object representations. Here, we used an automated controlled‐rearing method to examine whether visual experience with smoothly changing features facilitates the development of view‐invariant object recognition in a newborn animal model—the domestic chick (Gallus gallus). When newborn chicks were reared with a virtual object that moved smoothly over time, the chicks created view‐invariant representations that were selective for object identity and tolerant to viewpoint changes. Conversely, when newborn chicks were reared with a temporally non‐smooth object, the chicks developed less selectivity for identity features and less tolerance to viewpoint changes. These results provide evidence for a “smoothness constraint” on the development of invariant object recognition and indicate that newborns leverage the temporal smoothness of natural visual environments to build abstract mental models of objects. 相似文献

Physicians are free to prescribe the drugs they consider the best for their patients, and simultaneously required to seek healthcare’ cost-effectiveness — especially after patents expiry. While the physician choice of a given molecule is indisputable, French pharmacists gradually gained a large power to choose the brands on chemicals’ and biologics’ competitive markets. In May 2018, the highest judicial Court decided the physician must expressly motivate his exclusive choice of a given brand, and can not simply refuse the brand’ substitution by pharmacists. This unprecedented requirement is extrapolable to all substitutable drugs in France (registered generics and biosimilars). It raises the possible examination of medical choice motives — but in our opinion, it finishes, rather than it opens the arms race between prescribers and mandatory health insurers in France. 相似文献

This study aimed to examine the effects of gambling motives and competitive gambling outcomes on opponent likeability and targeted physical aggression. We hypothesized that (a) losers would perceive their opponents to be less likeable and (b) would be physically more aggressive toward their opponents. Opponent likeability was proposed to mediate the lose–aggression relationship while social gambling motives were proposed to moderate the lose–aggression relationship. Specifically, we expected that losers of competitive gambling situations would engage in greater physical aggression only if they perceived their opponents to be less likeable. In addition, lower perceived opponent likeability would translate into greater targeted physical aggression only if the loser possessed low social motives for gambling. Ninety‐eight undergraduates who self‐identified mostly as recreational gamblers participated in a competitive gambling game. The Hot Sauce Paradigm was adapted as a measure of targeted physical aggression. Results obtained supported our hypotheses. Potential implications and limitations are discussed. 相似文献

We used meta-analysis to test for gender differences in implicit needs for affiliation/intimacy, assessed via story-coding methods. We included thirty-three effect sizes from 26 publications and 2 unpublished studies, covering a total of 5962 research participants (58% female). Across studies, women scored higher than men in measures of implicit affiliation motivation (d1 = 0.45, 95%CI = [0.37; 0.53]). This finding was not moderated by the coding system used, gender congruence of the picture cues presented, or correction for protocol length. Men and women did not differ in their implicit needs for power (N = 2493, k = 15, d1 = −0.19, 95%CI = [−0.44; 0.05]) or achievement (N = 2235, k = 13, d1 = 0.14, 95%CI = [−0.03; 0.30]). 相似文献

The present study investigates whether knowledge about the intentional relationship between gesture and speech influences controlled processes when integrating the two modalities at comprehension. Thirty-five adults watched short videos of gesture and speech that conveyed semantically congruous and incongruous information. In half of the videos, participants were told that the two modalities were intentionally coupled (i.e., produced by the same communicator), and in the other half, they were told that the two modalities were not intentionally coupled (i.e., produced by different communicators). When participants knew that the same communicator produced the speech and gesture, there was a larger bi-lateral frontal and central N400 effect to words that were semantically incongruous versus congruous with gesture. However, when participants knew that different communicators produced the speech and gesture--that is, when gesture and speech were not intentionally meant to go together--the N400 effect was present only in right-hemisphere frontal regions. The results demonstrate that pragmatic knowledge about the intentional relationship between gesture and speech modulates controlled neural processes during the integration of the two modalities. 相似文献
