Volitional action and inaction in the lives of undergraduate students: State orientation, procrastination and proneness to boredom

The purpose of this research was to examine the relation between state orientation, proneness to boredom and procrastination as proposed in Kuhl's theory of action (Kuhl, 1994a). The findings from two studies are reported. Based on data collected from 143 undergraduate students on the Action Control Scale (Kuhl, 1994b), study 1 revealed arousal, avoidance and decisional procrastination to be positively related to state orientation. Results of study 2 (n = 120) demonstrated proneness to boredom to be positively related to state orientation, arousal procrastination and decisional procrastination. Overall, this research provides support for a link between proneness to boredom, state orientation, and procrastination. The results are discussed in terms of self-identity and time perception.     

An investigation of hierarchical Bayes procedures in item response theory

Hierarchical Bayes procedures for the two-parameter logistic item response model were compared for estimating item and ability parameters. Simulated data sets were analyzed via two joint and two marginal Bayesian estimation procedures. The marginal Bayesian estimation procedures yielded consistently smaller root mean square differences than the joint Bayesian estimation procedures for item and ability estimates. As the sample size and test length increased, the four Bayes procedures yielded essentially the same result.The authors wish to thank the Editor and anonymous reviewers for their insightful comments and suggestions.     

A SCIENTIST AND A THEOLOGIAN SEE THE WORLD: COMPROMISE OR SYNTHESIS?

Abstract. A scientist (for whom the world is the universe) and a theologian (for whom the world is planet Earth) engage in dialogue, not contrived Platonic or Galilean dialogue, but true bidisciplinary dialogue that strives for higher viewpoint. S: Is the preservation of the human species a primary human responsibility? T: It may be a responsibility we share with God. S: The human species has a limited future if confined to the planet Earth. We must diversify our habitat by colonizing space. T: We are responsible for other life on the planet as well. The discussants conclude that besides protecting Earth ecologies, we should create new ecologies in space.     

Symbolic comparison of color similarity

This study investigated symbolic comparison of color similarity using a triplet paradigm. Results showed that the time to choose which of two color samples is more similar to a color name was a function of several measures of distance between the samples relative to the focal color for the category name. Since colors appear to be represented in memory only as names and images and not as abstract entities such as features or propositions, these results provide support for models of symbolic comparison that assume that items are stored and compared as mental analogs.     

An evaluation of touch-screen input for a HyperCard-based digit-span task

The touch screen appears to be an ideal input device for human subjects in many research applications in psychology. Nonetheless, the research on relative merits of input devices is inconclusive. The present experiments were carried out to compare touch-screen, mouse, and voice responses on a HyperCard-based digit-span task. The results indicated that touch-screen input has no advantage in comparison to the use of a mouse, but that it produces better performance than voice response does. The latter finding, however, may be an artifact of visual cues embedded in this implementation of the digit-span task.     

Ethnic differences in subclinical paranoia: an expansion of norms of the paranoia scale

The Paranoia Scale (PS) was designed to assess subclinical paranoid ideation (A. Fenigstein & P. A. Vanable, 1992). Despite its established validity, the PS has several problems that need to be addressed. There are no normative data on ethnic minority groups such as African Americans, making it difficult to interpret this group's performance on the PS. Data from the present research revealed that African Americans scored higher on the PS than non-Hispanic Whites. However, interpretation of these findings should be tempered as they may reflect other contextual factors such as discrimination and the impact of racism. Implications for using the PS with African Americans and possible explanations for the observed results were discussed.     

Temporal bisection with trial referents.

In temporal bisection, the subject is required to compare the similarity of a probe duration with two referent durations. Two bisection experiments with human subjects are reported in which performance under three referent conditions was compared. In two of the conditions, no-referent and fixed-referent, the referent pair was constant throughout the session and was varied between sessions. In the no-referent condition, samples of the referents were presented at the beginning of a block of trials, but not on the probe trials. In contrast, in the fixed-referent condition, the referent pair was presented on each probe trial. In the third referent condition, roving-referent, the referent pair was also presented on each probe trial, but the values of the pair varied during a session rather than between sessions. The pseudologistic Model (PLM; Killeen, Fetterman, & Bizo, 1997) provided an excellent account of the data from all referent conditions and indicated that (1) the scalar variability was located in the perception of the probe and was independent of the structure of the bisection task, (2) the role of the referents was to set the criterion, (3) the probe was compared with the criterion rather than with the referents, and (4) the comparison of the probe with the criterion occurred even when trial referents were available.     

De‐schooling the Theological Seminary: An Appropriate Paradigm for Effective Ministerial Formation

The most common paradigm of contemporary Protestant theological education for ministerial formation is that of schooling, seen in the institution of the theological seminary/college. This article notes the limitations of the schooling paradigm for educational intervention in the range of domains inherent in effective ministerial formation; recognizes that teaching and learning take different but still legitimate shape when used to describe educational processes in this context; and argues for an integrated, formational, and missional community paradigm modeled especially on the relationship of Jesus with his disciples as being both more consistent with biblical precedents and more effective educationally. The implications of this for the role of faculty of theological institutions are explored.

In temporal bisection, the subject is required to compare the similarity of a probe duration with two referent durations. Two bisection experiments with human subjects are reported in which performance under three referent conditions was compared. In two of the conditions, no-referent and fixed-referent, the referent pair was constant throughout the session and was varied between sessions. In the noreferent condition, samples of the referents were presented at the beginning of a block of trials, but not on the probe trials. In contrast, in the fixed-referent condition, the referent pair was presented on each probe trial. In the third referent condition, roving-referent, the referent pair was also presented on each probe trial, but the values of the pair varied during a session rather than between sessions. The pseudologistic Model (PLM; Killeen, Fetterman, & Bizo, 1997) provided an excellent account of the data from all referent conditions and indicated that (1) the scalar variability was located in the perception of the probe and was independent of the structure of the bisection task, (2) the role of the referents was to set the criterion, (3) the probe was compared with the criterion rather than with the referents, and (4) the comparison of the probe with the criterion occurred even when trial referents were available.
