Learning Through Shared Christian Praxis: Reflective Practice in the Classroom

The cultivation of reflective practice has become a commonly accepted goal of theological education. However, theological educators must face the challenge of teaching and assessing reflective practice. Hypothesizing that this concern is best addressed in community, the authors of this article devised a collaborative action‐research project using Thomas Groome's “shared Christian praxis” model. They describe the ways in which they have, over the course of the project, modified their pedagogy to improve their students' reflection on practice.     

Impact of rumination versus distraction on anxiety and maladaptive self-beliefs in socially anxious individuals

A large body of experimental evidence has demonstrated the adverse effects of rumination on depressive mood and cognitions. In contrast, while prominent models of social phobia (Clark & Wells, 1995; Rapee & Heimberg, 1997) have proposed rumination as a key maintaining factor, the effects of rumination in social anxiety have not been extensively explored. In a sample of (N = 93) undergraduates, this study investigated the impact of rumination versus distraction following a social-evaluative task on anxiety and another key component of social phobia: maladaptive self-beliefs. Relative to distraction, rumination maintained anxiety in both high and low socially anxious individuals, and maintained unconditional beliefs in high socially anxious individuals. The results support models of social phobia and also suggest important theoretical extensions. Implications for the treatment of social anxiety are discussed.     

Hope versus optimism in Singaporean adolescents: Contributions to depression and life satisfaction

This study explored the discriminant validity of optimism and hope in accounting for unique variance in depression and life satisfaction for 334 secondary school students from Singapore. Correlational analysis showed that optimism and hope were significantly correlated with each other. Hierarchical multiple regression findings indicated that both optimism and hope significantly predicted depression and life satisfaction even after controlling for hope and optimism, respectively. However, the incremental unique variance accounted for in depression by optimism is 6% more than that accounted for by hope in terms of R² Change values. Simultaneous multiple regression analyses using the subscale scores found that only agency, optimism, and pessimism contributed uniquely to the variance in depression and life satisfaction. Implications and limitations of these findings are discussed.     

Unification of psychophysical phenomena: The complete form of Fechner’s law

Many of the laws and empirical observations of fundamental psychophysics can be unified with a single equation, which has been called the complete form of Fechner’s law. It can be shown that this law embraces both of the commonly used forms: Stevens’s and Fechner’s laws. It assumes one or the other form with appropriate values of the parameters. However, the complete equation confers an advantage beyond simply containing the classical laws. It offers greater flexibility in the representation of experimental data. It is shown that psychophysical phenomena may be represented by any number of triplets of quantities: subjective magnitude of stimulus, subjective just noticeable difference (jnd), and differential threshold. Each of the preceding quantities are functions of the physical magnitude of the stimulus. The investigator has the license to choose two of these quantities in the form he or she thinks is best; the third quantity is determined by the choice of the first two. Thus, for example, different forms of the law of sensation and different forms of the mathematical function for differential threshold may coexist with equal validity.     

MMPI Scale Five: its meaning, or lack thereof

As a widely used test of personality and psychopathology, the MMPI play an important part in making decisions that affect people's lives. The addition of "cookbooks" and, more recently, computer-generated output based on MMPI scale scores provide even the most unsophisticated user with what appear to be credible and valid interpretations of scale and profile variations. A comprehensive review of the literature on MMPI Scale Five (MJ) calls into question generalizations arising from scores on the scale. Empirical research provides no consistent meaning for any score level on the scale. Attempts to map the structure of the scale result in numerous factors and account for, at best, 30% of the variance. Discussion focuses on the shortcomings of the scale as well as the assumptions on which it was developed. Conclusions suggest that the concept of sex difference itself is inappropriately defined and establishes artificial boundaries.     

Sharp targets are detected better against a figure, and blurred targets are detected better against a background

There is growing evidence that the performance of perceptual tasks is often facilitated by perceived "figureness." Accuracy in detection and discrimination of targets is higher when the targets are presented in figural regions than when they are presented in ground regions of an image. This "figure superiority" might be a result of a functional specialization in the visual analysis of figure; recent theories have also assumed a functional specialization in the visual analysis of ground. If so, we might expect "ground superiority" in situations where task performance requires information available primarily through analysis of ground. We manipulated the spatial frequency of a small line segment and found that when it was sharp (i.e., the high-spatial-frequency components were present), it was detected better in figural regions, but when we blurred it (only the low-to-medium spatial frequencies were present) it was detected better in ground regions. These findings support the view that figure and ground analyses involve different specialized functions.     

The effect of visual-vestibular conflict on the latency of steady-state visually induced subjective rotation

Two experiments were carried out to test the hypothesis that the long onset latency of steady-state subjective rotation induced by rotating a tall striped drum around a stationary observer is the result of visual-vestibular conflict. A reduction of this conflict should, therefore, reduce the length of the latency period. In Experiment 1, visual-vestibular conflict was reduced by providing the observers with corroborating vestibular stimulation at the start of optokinetic stimulation. Onset latencies were found to be significantly shortened with corroborating vestibular stimulation, but to be unaffected by noncorroborating vestibular stimulation. In Experiment 2, testing was done on a group of patients with unilateral (right labyrinth) Ménière’s disease, which produces decreased vestibular sensitivity to rightward body rotation and increased vestibular sensitivity to leftward body rotation. Visual-vestibular conflict during subjective rotation to the right should therefore be decreased, while during leftward subjective rotation it should be increased. The prediction that the latency to steady-state subjective rotation should be shorter than normal with subjective rotation to the left was supported.     

Personality, Self-Disclosure and Friendship Between Chinese University Roommates

The present study examined the relations among personality perceptions, self-disclosing behavior, and friendship strength between Chinese roommates. These variables are rarely measured together and, when jointly assessed, allow for the disentanglment of personality factors from the social behavior of self-disclosure, making it possible to assess the role of self-disclosure behavior in the nexus of personality perceptions relating to friendship. One hundred and thirty-one university students rated their own and their roommate's personality, their self-disclosing behavior, and the strength of their friendship six months after being assigned to room together. It was found that self-ratings on the personality dimension of application were related both to one's friendship ratings and one's self-disclosing behavior, suggesting that personality variation is responsible for some of the well-established (Collins and Miller, 1994) links between self-disclosure and friendship strength. After controlling for self-rated application, it was found that both the respondent's and the roommate's self-disclosing behavior contributed separately to increasing the respondent's friendship ratings, as has also been found in Western research. Surprisingly, respondent self-disclosure was unrelated to how respondents perceived their roommates. However, the perceived roommate qualities of helpfulness and intellect were associated with the respondent's friendship ratings, suggesting that other, unmeasured social behaviors are being exchanged between roommates to enhance their friendship. Future research should examine these other behavioral mediators of friendship, so that we can develop a behavioral topology for this important social relationship and link these behaviors to dimensions of interpersonal perception.
