To walk independently, the human infant must coordinate its multisegmented body to achieve both postural stability and forward mobility. In this experiment, we sought evidence of the form this coordination takes in infants who have been walking 3 to 10 months. Using the Philippson phases to represent the step cycle, we analyzed film records of infants and adults walking at speeds from 2 to 4 km/hr. Our results reveal a clear relationship between walking speed and the F and E(3) Philippson phases of the step cycle in both the young walkers and the adults. Indeed, across all four phases of the step cycle, the infants exhibited an organization that was almost identical to that of the mature walkers. 相似文献

Masculinity, femininity, type A behavior, and psychosocial adjustment in medical students 总被引:1,自引:0,他引:1
The freshman class of a midwestern medical school completed measures of masculinity and femininity, Type A behavior, and a variety of dependent variables concerning psychological well-being, adjustment, and interpersonal satisfaction. Appropriate statistical treatment of the data revealed strong and consistent masculinity effects on neuroticism, depression, self-esteem, confidence, hedonic capacity, locus of control, and relationship satisfaction. Femininity main effects varied in number as a function of the statistical method employed and involved a more diverse group of variables than is typically reported. Additive androgyny formulations of mental health were supported; balance androgyny formulations were not. No evidence for a Type A X Masculinity effect on adjustment was found. Discussion focuses on the correct interpretation of masculinity and femininity scales, comparability of analysis of variance (ANOVA) and multiple regression statistical analyses, and the viability of the concept of androgyny. 相似文献

A substantial literature indicates that anxiety is often associated with selective attention to threat cues. Socially anxious individuals are excessively concerned about negative evaluation by others. One might therefore predict that high social anxiety would be associated with selective attention to negative facial expressions. On the other hand, some recent models have suggested that social anxiety may be associated with reduced processing of external social cues. A modified dot-probe task was used to investigate face attention. High and low socially anxious individuals were presented with pairs of pictures, consisting of a face (positive, neutral, or negative) and a household object, under conditions of social-evaluative threat or no threat. The results indicated that, compared to low socially anxious individuals, high socially anxious individuals show an attentional bias away from emotional (positive and negative) faces but this effect is only observed under conditions of social-evaluative threat. Theoretical and clinical implications of the results are discussed. 相似文献

According to psychotherapy outcome literature, treatments for major depressive disorder (MDD) yield impressive results. Study after study demonstrates the efficacy of brief, evidence-based interventions for depressed individuals. Nevertheless, MDD continues to exact a devastating toll on modern society. The World Health Organization has identified it as the leading cause of disability worldwide. This reality is surprising given the implications from the academic literature. A historical analysis of MDD treatment suggests that most people with MDD experienced complete remission and enhanced outcomes when long-term, psychodynamically influenced treatments prevailed. An analysis of the system that perpetuates the brief intervention model for MDD, managed care, is discussed. This analysis is followed by a case study that illustrates the harm managed care can do to patients with MDD who are not permitted treatment of longer duration. Implications and recommendations for psychologists to intervene at the micro and macro levels are discussed. 相似文献

Latent change score models (LCS) are conceptually powerful tools for analyzing longitudinal data (McArdle & Hamagami, 2001). However, applications of these models typically include constraints on key parameters over time. Although practically useful, strict invariance over time in these parameters is unlikely in real data. This study investigates the robustness of LCS when invariance over time is incorrectly imposed on key change-related parameters. Monte Carlo simulation methods were used to explore the impact of misspecification on parameter estimation, predicted trajectories of change, and model fit in the dual change score model, the foundational LCS. When constraints were incorrectly applied, several parameters, most notably the slope (i.e., constant change) factor mean and autoproportion coefficient, were severely and consistently biased, as were regression paths to the slope factor when external predictors of change were included. Standard fit indices indicated that the misspecified models fit well, partly because mean level trajectories over time were accurately captured. Loosening constraint improved the accuracy of parameter estimates, but estimates were more unstable, and models frequently failed to converge. Results suggest that potentially common sources of misspecification in LCS can produce distorted impressions of developmental processes, and that identifying and rectifying the situation is a challenge. 相似文献

The present longitudinal study examined religious beliefs and behaviors, spiritual health locus of control (SHLOC), and selected health-related behaviors and outcomes in a national sample of 766 African American adults. Participants were interviewed by telephone three times over a 5-year period. Results indicated that stronger religious beliefs and religious behaviors were associated with greater changes in active SHLOC. There was some evidence of direct effects of religious beliefs and behaviors on changes in health behaviors. Religious behaviors were related to greater passive SHLOC over time across some health outcomes. Passive SHLOC was associated with some less desirable health outcomes over time. 相似文献

Chronic pain impacts individuals with pain as well as their loved ones. Yet, there has been little attention to the social context in individual psychological treatment approaches to chronic pain management. With this need in mind, we developed a couple-based treatment, “Mindful Living and Relating,” aimed at alleviating pain and suffering by promoting couples’ psychological and relational flexibility skills. Currently, there is no integrative treatment that fully harnesses the power of the couple, treating both the individual with chronic pain and the spouse as two individuals who are each in need of developing greater psychological and relational flexibility to improve their own and their partners’ health. Mindfulness, acceptance, and values-based action exercises were used to promote psychological flexibility. The intervention also targets relational flexibility, which we define as the ability to interact with one’s partner, fully attending to the present moment, and responding empathically in a way that serves one’s own and one’s partner’s values. To this end, the intervention also included exercises aimed at applying psychological flexibility skills to social interactions as well as emotional disclosure and empathic responding exercises to enhance relational flexibility. The case presented demonstrates that healthy coping with pain and stress may be most successful and sustainable when one is involved in a supportive relationship with someone who also practices psychological flexibility skills and when both partners use relational flexibility skills during their interactions. 相似文献
