All children in Grades 3 through 12 of one school system completed a survey about health habits and beliefs including smoking and eating habits, perceptions of exercise, weight, and parental involvement in health. The surveys were factor-analyzed within grade and sex, and the overall factors that emerged were Smoking Habits, Family Discussion of Health, Family Thinking About Health, Nutritional Habits, and Health Locus of Control. Analysis of variance of each factor revealed that girls generally reported healthier food habits than did boys. However, girls reported more smoking and less exercise. There are also changes in habits and belief with age; junior high school is a particularly important time for the development of several habits. The findings are discussed in relation to theories of child development and the implications for the content and timing of future health education intervention programs with children. 相似文献

The need to bridge the gap between western based psychotherapeutic intervention and African psychotherapeutic interventions is the main objective of this paper. In order to do this, cross cutting issues in psychotherapy in Nigeria were reviewed. This review covered socio cultural, economic conditions and other contemporary issues such as child maltreatment, HIV/AIDS, chronic illness, terrorism and the impact of western civilization on Nigerian culture and how it has produced a heterogeneous Nigerian society described as westernized, traditional and transitional types of Nigerians. Also salient peculiarities that must be taken into consideration in bridging the gap between western and African based psychotherapy were identified. Some of these salient peculiarities were adumbrated and they include frequent somatic complaints of psychological origin, beliefs in spirits including ancestral spirits, independent spirits and the supreme spirit God to whom duties are owed to keep the moral order. Given this situation the authors expressed uncertainty in the use of western diagnostic illness categories. Also an attempt was made to describe traditional methods of treatment such as the popular prayer houses and traditional healers. From lessons learnt based on these cross cutting issues the authors reported the development of Harmony Restoration Therapy and Meseron treatment frameworks as attempts at indigenizing western psychotherapeutic methods. From these they proposed the way forward as a cultural blend through using culture based psychotherapeutic framework. This they suggest can be applied in other societies. 相似文献

We introduce a novel platform for interactive studies, that is, any form of study in which participants’ experiences depend not only on their own responses, but also on those of other participants who complete the same study in parallel, for example a prisoner’s dilemma or an ultimatum game. The software thus especially serves the rapidly growing field of strategic interaction research within psychology and behavioral economics. In contrast to all available software packages, our platform does not handle stimulus display and response collection itself. Instead, we provide a mechanism to extend existing experimental software to incorporate interactive functionality. This approach allows us to draw upon the capabilities already available, such as accuracy of temporal measurement, integration with auxiliary hardware such as eye-trackers or (neuro-)physiological apparatus, and recent advances in experimental software, for example capturing response dynamics through mouse-tracking. Through integration with OpenSesame, an open-source graphical experiment builder, studies can be assembled via a drag-and-drop interface requiring little or no further programming skills. In addition, by using the same communication mechanism across software packages, we also enable interoperability between systems. Our source code, which provides support for all major operating systems and several popular experimental packages, can be freely used and distributed under an open source license. The communication protocols underlying its functionality are also well documented and easily adapted to further platforms. Code and documentation are available at https://github.com/psynteract/. 相似文献

Human infants as young as 14 to 18 months of age help others attain their goals, for example, by helping them to fetch out‐of‐reach objects or opening cabinets for them. They do this irrespective of any reward from adults (indeed external rewards undermine the tendency), and very likely with no concern for such things as reciprocation and reputation, which serve to maintain altruism in older children and adults. Humans' nearest primate relatives, chimpanzees, also help others instrumentally without concrete rewards. These results suggest that human infants are naturally altruistic, and as ontogeny proceeds and they must deal more independently with a wider range of social contexts, socialization and feedback from social interactions with others become important mediators of these initial altruistic tendencies. 相似文献

Previous research in group decision making has found that in situations of a hidden profile (i.e. the best choice alternative is hidden from individual members as they consider their pre‐discussion information), unshared information is disproportionately neglected and sub‐optimal group choices are highly likely. In an experimental study, three‐person groups decided which of three candidates to select for a professorial appointment. We hypothesised that minority dissent in pre‐discussion preferences improves the consideration of unshared information in groups and increases the discovery rate of hidden profiles. As predicted, consideration of unshared information increased with minority dissent. The expectation of an improvement of group decision quality was partially supported. In diversity groups (i.e. each member prefers a different alternative) consideration of unshared information and group decision quality was significantly higher than in simple minority groups. Results are discussed in the light of theories of minority influence. The benefits of using the hidden profile paradigm with minority and diversity groups for theory development in the area of group decision making are highlighted.

Developmental trajectories provide the empirical foundation for theories about change processes during development. However, the ability to distinguish among alternative trajectories depends on how frequently observations are sampled. This study used real behavioral data, with real patterns of variability, to examine the effects of sampling at different intervals on characterization of the underlying trajectory. Data were derived from a set of 32 infant motor skills indexed daily during the first 18 months. Larger sampling intervals (2-31 days) were simulated by systematically removing observations from the daily data and interpolating over the gaps. Infrequent sampling caused decreasing sensitivity to fluctuations in the daily data: Variable trajectories erroneously appeared as step functions, and estimates of onset ages were increasingly off target. Sensitivity to variation decreased as an inverse power function of sampling interval, resulting in severe degradation of the trajectory with intervals longer than 7 days. These findings suggest that sampling rates typically used by developmental researchers may be inadequate to accurately depict patterns of variability and the shape of developmental change. Inadequate sampling regimes therefore may seriously compromise theories of development. 相似文献

Exemplar theories of categorization depend on similarity for explaining subjects’ ability to generalize to new stimuli. A
major criticism of exemplar theories concerns their lack of abstraction mechanisms and thus, seemingly, of generalization
ability. Here, we use insights from machine learning to demonstrate that exemplar models can actually generalize very well.
Kernel methods in machine learning are akin to exemplar models and are very successful in real-world applications. Their generalization
performance depends crucially on the chosen similarity measure. Although similarity plays an important role in describing
generalization behavior, it is not the only factor that controls generalization performance. In machine learning, kernel methods
are often combined with regularization techniques in order to ensure good generalization. These same techniques are easily
incorporated in exemplar models. We show that the generalized context model (Nosofsky, 1986) and ALCOVE (Kruschke, 1992) are
closely related to a statistical model called kernel logistic regression. We argue that generalization is central to the enterprise of understanding categorization behavior, and we suggest some
ways in which insights from machine learning can offer guidance. 相似文献

Human prosocial behaviors are supported by early‐emerging psychological processes that detect and fulfill the needs of others. However, little is known about the mechanisms that enable children to deliver benefits to others at costs to the self, which requires weighing other‐regarding and self‐serving preferences. We used an intertemporal choice paradigm to systematically study and compare these behaviors in 5‐year‐old children. Our results show that other‐benefiting and self‐benefiting behavior share a common decision‐making process that integrates delay and reward. Specifically, we found that children sought to minimize delay and maximize reward, and traded off delays against rewards, regardless of whether these rewards were for the children themselves or another child. However, we found that children were more willing to invest their time to benefit themselves than someone else. Together, these findings show that from childhood, other‐ and self‐serving decisions are supported by a general mechanism that flexibly integrates information about the magnitude of rewards, and the opportunity costs of pursuing them.
