质疑星座决定人格特质的实证研究

星象学的基本假设是一个人出生时的星运位置可以决定其人格特质和重大际遇。本研究以16PF为工具,测查了165名大一学生,并按被试的出生日期和时辰确定了其星座。总的来说,结果不支持星座决定人格倾向的理论。     

Avoiding an EST Monopoly: Toward a Pluralism of Philosophies and Methods

We contend in this article that the EST movement is becoming an ideological and economic monopoly through the exclusive use of one philosophy of science—empiricism. This epistemology monopolizes the methods that produce the ESTs. We provide lists of the values and assumptions that other scholars have demonstrated is endemic to empirical research, and we provide here an in-depth discussion about one central, uninvestigated value of such research. We, then, show the impact of this value—bias and favoritism—not only on the research itself but also on what is deemed an EST. This is followed by a discussion of a non-monopolistic alternative, an alternative that disallows the relativism and anything goes of psychotherapys history but avoids the dogmatism of an exclusive ideology.     

Factors Predicting Intention to Enroll in a Philosophy of Life Course

This research examined factors predicting university students' intentions to enroll in a philosophy of life course. One hundred and ninety subjects participated in two surveys. The first was qualitative, identifying factors students considered in forming intentions, but without ranking the factors. The second study used a quantitative model to predict student intentions from their beliefs about the course, themselves, and other people. The model was based on Ajzen's theory of planned behavior, a theory that successfully predicts many different behaviors. Analysis was done using partial least squares, a robust structural equation modeling technique. The results show that students focused primarily on personal outcomes from the course. They wanted the course to help them understand life and themselves. To a lesser extent, students' perceptions of other people's views affected their intentions, especially the opinions of parents, friends, and religious people. Some students thought all beliefs are subjective, and discussing them would be pointless. Recommendations are given for designing and promoting philosophy of life courses.     

A derived transfer of simple discrimination and self-reported arousal functions in spider fearful and non-spider-fearful participants

Two experiments investigated the derived transfer of functions through equivalence relations established using a stimulus pairing observation procedure. In Experiment 1, participants were trained on a simple discrimination (A1+/A2-) and then a stimulus pairing observation procedure was used to establish 4 stimulus pairings (A1-B1, A2-B2, B1-C1, B2-C2). Subsequently, a transfer of the simple discrimination functions through equivalence relations was observed (e.g., C1+/C2-). These procedures were modified in Experiment 2, which demonstrated that spider-fearful and non-spider-fearful participants show differing levels of a transfer of self-reported arousal functions for stimuli used in equivalence relations with video-based material depicting scenes with spiders. The results demonstrate that the stimulus pairing observation procedure provides a viable alternative to matching-to-sample, and also offer tentative support for a derived-relations model of the acquisition of anxiety responses in at least one sub-clinical population.     

Empirical indistinguishability: From the knowledge structure to the skills

Recent literature has pointed out that the basic local independence model (BLIM) when applied to some specific instances of knowledge structures presents identifiability issues. Furthermore, it has been shown that for such instances the model presents a stronger form of unidentifiability named empirical indistinguishability, which leads to the fact that the existence of certain knowledge states in such structures cannot be empirically tested. In this article the notion of indistinguishability is extended to skill maps and, more generally, to the competence-based knowledge space theory. Theoretical results are provided showing that skill maps can be empirically indistinguishable from one another. The most relevant consequence of this is that for some skills there is no empirical evidence to establish their existence. This result is strictly related to the type of probabilistic model investigated, which is essentially the BLIM. Alternative models may exist or can be developed in knowledge space theory for which this indistinguishability problem disappears.     

Tests for linear trend in the smallest eigenvalues of the correlation matrix

A test for linear trend among a set of eigenvalues of a correlation matrix is developed. As a technical implementation of Cattell's scree test, this is a generalization of Anderson's test for the equality of eigenvalues, and extends Bentler and Yuan's work on linear trends in eigenvalues of a covariance matrix. The power of minimumx ² and maximum likelihood ratio tests are compared. Examples show that the linear trend hypothesis is more realistic than the standard hypothesis of equality of eigenvalues, and that the hypothesis is compatible with standard decisions on the number of factors or components to retain in data analysis.This work was supported by National Institute on Drug Abuse Grants DA01070 and DA00017.

Quartic rotation criteria and algorithms

Most of the currently used analytic rotation criteria for simple structure in factor analysis are summarized and identified as members of a general symmetric family of quartic criteria. A unified development of algorithms for orthogonal and direct oblique rotation using arbitrary criteria from this family is given. These algorithms represent fairly straightforward extensions of present methodology, and appear to be the best methods currently available.The research done by R. I.

Easy bayes estimation for rasch-type models

A Bayes estimation procedure is introduced that allows the nature and strength of prior beliefs to be easily specified and modal posterior estimates to be obtained as easily as maximum likelihood estimates. The procedure is based on constructing posterior distributions that are formally identical to likelihoods, but are based on sampled data as well as artificial data reflecting prior information. Improvements in performance of modal Bayes procedures relative to maximum likelihood estimation are illustrated for Rasch-type models. Improvements range from modest to dramatic, depending on the model and the number of items being considered.This research was supported by ORN Contact #00014-86-K0087. We wish to thank Sheng-Hui Chu and Dzung-Ji Lii for providing intelligent and energetic programming support for this article. We also thank one of the reviewers for pointing out several interesting and useful perspectives.     

THE WHOLE BRAIN AS THE BASIS OR THE ANALOGICAL EXPRESSION OF GOD

Abstract. As human beings we inevitably try to explain our experience. In philosophical language, we deal with transcendent assertions and aspirations. The issue, then, is: how can we talk about what matters, given the structures inherent in language and basic to the way we are made? Instead of the philosophical category of Being, I advance a case for giving the human brain privileged status as an analogical expression of God, the symbol-concept of what matters most, and then suggest the illumination which can come with using that analogical expression, especially as that analogy connects us with the environment at the limbic level and constructs our world at the cerebral level.
