How do I feel about the behavior? The interplay of affective associations with behaviors and cognitive beliefs as influences on physical activity behavior.

Individuals have affective associations with health behaviors. In other domains such associations have been shown to influence behavior, but affective associations with health behaviors are not included in current health decision-making models. The authors examined whether affective associations with exercise predicted individuals' activity behavior and, if so, how they interfaced with other decision-making constructs to influence behavior. Adult participants (N = 433) reported their current physical activity behavior and affective associations with physical activity. Health belief model and theory of planned behavior constructs were also assessed. More positive affective associations with activity significantly predicted greater activity behavior. Moreover, the influence of the health belief model and theory of planned behavior constructs on activity behavior was mediated through affective associations. Affective associations were shown to play a central role in individuals' activity behavior, both as a mediator of the effects of cognitively based decision-making factors and as an independent predictor of activity behavior. The results suggest the need to include affective influences on behavior in formal models of health decision making and, potentially, to explore affectively based intervention routes to change behaviors.

The Health Professional Ethics Rubric: Practical Assessment in Ethics Education for Health Professional Schools

A barrier to the development and refinement of ethics education in and across health professional schools is that there is not an agreed upon instrument or method for assessment in ethics education. The most widely used ethics education assessment instrument is the Defining Issues Test (DIT) I & II. This instrument is not specific to the health professions. But it has been modified for use in, and influenced the development of other instruments in, the health professions. The DIT contains certain philosophical assumptions (??Kohlbergian?? or ??neo-Kohlbergian??) that have been criticized in recent years. It is also expensive for large institutions to use. The purpose of this article is to offer a rubric??which the authors have named the Health Professional Ethics Rubric??for the assessment of several learning outcomes related to ethics education in health science centers. This rubric is not open to the same philosophical critiques as the DIT and other such instruments. This rubric is also practical to use. This article includes the rubric being advocated, which was developed by faculty and administrators at a large academic health science center as a part of a campus-wide ethics education initiative. The process of developing the rubric is described, as well as certain limitations and plans for revision.     

Conceptual layers and strategies in tour planning

We present an exploratory study of an everyday navigation planning situation, addressing spatial planning strategies as well as cognitive shifts between the visually available map and the conceptualized real-world environment. Participants were asked to plan a diversified holiday route on an island, with the help of a map representing spatial as well as activity information. Following the task proper, they reported in written form about the problem-solving process. Route trajectories were analyzed with respect to their properties, and reports were analyzed with respect to the represented concepts and linguistic patterns. Results reveal that route trajectories tended to be circular rather than random, with relatively few detours or crossing lines. The underlying spatial planning strategies as represented in the written reports resembled earlier findings on the Traveling Salesperson Problem, providing insights into the extent to which this abstract task transfers to a naturalistic scenario. Most crucially, our linguistic analysis provides new results about the representation of conceptual layers when considering the real-world navigation domain of traveling in relation to the actual table-top map planning domain.     

Outline of a new principle of mathematical psychology (1851)

Summary The paper presents a translation of Appendix 2 of the second volume of Fechner's Zend-Avesta (1851), which contains the first outline of psychophysics as the quantitative science of mind-body relations. Fechner argues that mathematical psychology must be based on observation of physical phenomena, because observation of mental phenomena results in equality judgments only. The logarithmic formula is not yet based on Weber's law, but on various observations showing that mental intensities increase at a slower rate than the corresponding physical intensities. The physical substrate of mental phenomena is oscillatory and can be decomposed into a main wave and ripples superimposed on it, a conception which is illustrated by attentional phenomena and by sleeping and waking. The notion of negative sensations is introduced and discussed. A variant of the logarithmic law is proposed for higher mental activities. Throughout, Fechner's main concern is with what he called inner psychophysics in his later writings.Translated and edited by Eckart Scheerer Selection from: G. T.

First-order factor structure of the Personality Research Form

To establish the first-order factor structure of the Personality Research Form, a high school sample of 327 boys and a college sample of 215 men and women were administered Form AA. Principal component analyses were made, in both samples, of the 20 scales subdivided into two subsets. Nine factors were found to be equivalent in the college and high school data. Comparison with Edwards and Abbott analyses revealed substantial agreement. It was concluded that 12 scales could be used to measure the constructs embodied in the Personality Research Form.     

Reasoning about curvilinear motion: Using principles or analogy

People possess implicit theories about the motion of objects, theories that are often incorrect. When asked to predict the path of an object emerging from a curved tube, for example, people often say that the object will continue to follow a curved path. However, when solving a problem that reminds them of a familiar previous instance, people often reason by analogy to the instance. In this study, we show that a previous instance must be very superficially similar to a problem in order to be used as an analogy; otherwise, people will use their implicit theories as the basis of their reasoning.     

Deterministic Chaos and Computational Complexity: the Case of Methodological Complexity Reductions

Some problems rarely discussed in traditional philosophy of science are mentioned: The empirical sciences using mathematico-quantitative theoretical models are frequently confronted with several types of computational problems posing primarily methodological limitations on explanatory and prognostic matters. Such limitations may arise from the appearances of deterministic chaos and (too) high computational complexity in general. In many cases, however, scientists circumvent such limitations by utilizing reductional approximations or complexity reductions for intractable problem formulations, thus constructing new models which are computationally tractable. Such activities are compared with reduction types (more) established in philosophy of science. This revised version was published online in August 2006 with corrections to the Cover Date.
