In this article I show how we can give a formal representation and analysis of evolutions in artistic style, using the work of the painter Mondrian as an example. Capitalising on the idea that radical change in thought implies related changes in judgement criteria, we can in a “logic of development” specify the relations within, and between, those different sets of artistic judgement criteria that are considered typical of successive stages in artistic development. I discuss some of the problems involved in dealing with post-conventional thinking and judgement. Then I propose five major steps in Mondrian's artistic quest, showing how it is different—and how different it is—from other kinds of (e.g. moral or aesthetic) judgement development. Whereas many kinds of conceptual development lead to (various types of) criterion expansion, this form of entirely postconventional development goes in the opposite direction of a most stringent criterion reduction. 相似文献
The coefficient of variation is an effect size measure with many potential uses in psychology and related disciplines. We propose a general theory for a sequential estimation of the population coefficient of variation that considers both the sampling error and the study cost, importantly without specific distributional assumptions. Fixed sample size planning methods, commonly used in psychology and related fields, cannot simultaneously minimize both the sampling error and the study cost. The sequential procedure we develop is the first sequential sampling procedure developed for estimating the coefficient of variation. We first present a method of planning a pilot sample size after the research goals are specified by the researcher. Then, after collecting a sample size as large as the estimated pilot sample size, a check is performed to assess whether the conditions necessary to stop the data collection have been satisfied. If not an additional observation is collected and the check is performed again. This process continues, sequentially, until a stopping rule involving a risk function is satisfied. Our method ensures that the sampling error and the study costs are considered simultaneously so that the cost is not higher than necessary for the tolerable sampling error. We also demonstrate a variety of properties of the distribution of the final sample size for five different distributions under a variety of conditions with a Monte Carlo simulation study. In addition, we provide freely available functions via the MBESS package in R to implement the methods discussed. 相似文献
Objective. A randomised controlled trial (RCT) was conducted to evaluate a three-hour face-to-face physical activity (PA) intervention in community-dwelling older German adults with four groups: The intervention group (IG) received behaviour change techniques (BCTs) based on the health action process approach plus a views-on-ageing component to increase PA. The second intervention group ‘planning’ (IGpl) contained the same BCTs, only substituted the views-on-ageing component against an additional planning task. An active control group received the same BCTs, however, targeting volunteering instead of PA. A passive control group (PCG) received no intervention.
Design. The RCT comprised 5 time-points over 14 months in N = 310 participants aged 64+.
Main outcome measures. Self-reported as well as accelerometer-assessed PA.
Results. Neither PA measure increased in the IG as compared to the other groups at any point in time. Bayes analyses supported these null-effects.
Conclusion. A possible explanation for this null-finding in line with a recent meta-analysis is that some self-regulatory BCTs may be ineffective or even negatively associated with PA in interventions for older adults as they are assumed to be less acceptable for older adults. This interpretation was supported by observed reluctance to participate in self-regulatory BCTs in the current study. 相似文献
Objective: Planning can bridge the gap between intentions and action, but what bridges the gap between planning and action? This study helps to answer the question by disentangling the interrelationships between self-efficacy, planning and preparatory behaviours in predicting physical activity. Preparatory behaviours are tested as a working mechanism of planning. Moreover, it is tested whether the utility of preparatory behaviours depends on an individual’s level of self-efficacy.Methods: A survey assessed planning, self-efficacy and preparatory behaviours for physical activity. Adults (N = 166) provided data at two measurement points. In a longitudinal model, preparatory behaviours were specified as a mediator between planning and physical activity. Self-efficacy was specified as a possible moderator at two points in the model.Results: Preparatory behaviours mediated the relationship between planning and physical activity. An interaction between self-efficacy and preparatory behaviours on physical activity was found, indicating that individuals with low self-efficacy beliefs were more active if they engaged more frequently in preparatory behaviours.Conclusion: Planning seems to stimulate preparatory behaviours, which in turn make future physical activity more likely. Furthermore, as performing preparatory behaviours represent a step forward towards the enactment of behavioural goals, preparatory behaviours may be particular beneficial for individuals afflicted by self-doubts regarding physical activity. 相似文献
The Clinical Exchange invites eminent clinicians of diverse persuasions to share, in ordinary language, their clinical formulations and treatment plans of the same psychotherapy patient—one not selected or nominated by those therapists—and then to discuss points of convergence and contention in their recommendations. This Exchange concerns a Mr. L, a 47-year-old, married man presenting for outpatient individual psychotherapy with chief complaints of depression, anxiety, and a lengthy history of vocational underachievement. Drs. Herbert Fensterheim, Leslie Greenberg, and Leigh McCullough, who anchor their practices in the cognitive-behavioral, experiential, and psychodynamic orientations, respectively, are the featured commentators. Finally, Dr. Jerold Gold, the case contributor and Mr. L's psychotherapist, provides a few closing comments. 相似文献
This paper explores whether the highest stage in ego development is indicative of ego-transcendence as I initially surmised. Overall, I will explore some of the similarities and differences between rational awareness of the limits of representational thought and genuine postsymbolic knowing. I will present the research territory with a linear and a non-linear model of human development. Both models can accommodate both Eastern and Western self theories including ego development theory and Alexander's levels of mind. Next, I will outline an alternative developmental trajectory based on Alexander's notion of the shifts in the dominant mode of processing from personal–verbal–discursive to transpersonal–postsymbolic. Then, I will present ego development theory as I conceive of it now and outline the important characteristics of the highest stage (Cook-Greuter, 1999). Finally, I will consider the question of whether and in what way the Unitive ego stage is related to higher consciousness and introduce two testable propositions to clarify the issue. 相似文献
