Sometimes-competing retrieval (SOCR): a formalization of the comparator hypothesis

Cue competition is one of the most studied phenomena in associative learning. However, a theoretical disagreement has long stood over whether it reflects a learning or performance deficit. The comparator hypothesis, a model of expression of Pavlovian associations, posits that learning is not subject to competition but that performance reflects a complex interaction of encoded associative strengths. That is, subjects respond to a cue to the degree that it signals a change in the likelihood or magnitude of reinforcement relative to that in the cue's absence. Initially, this performance-focused view was supported by studies showing that posttraining revaluation of a competing cue often influences responding to the target cue. However, recently developed learning-focused accounts of retrospective revaluation have revitalized the debate concerning cue competition. Further complicating the picture are phenomena of cue facilitation, which have been addressed less frequently than cue competition by formal models of conditioning of either class. The authors present a formalization and extension of the comparator hypothesis, which results in sharpened differentiation between it and the new learning-focused models.     

Reputation as a moderator of political behavior-work outcomes relationships: a two-study investigation with convergent results

Personal reputation has been acknowledged to have an important influence on work outcomes. However, substantive research has been relatively scarce to date. The 2-study research plan reported here supports reputation's role as a moderator of the relationships between political behavior and the work outcomes of uncertainty, emotional exhaustion, and job performance ratings (i.e., self- and supervisor report). The 1st investigation contained both a pilot study, which was undertaken to demonstrate the consistency of self- and others' perceptions of reputation, and a test of the substantive relationships. The 2nd study served as a constructive replication of the hypothesized relationships. Supporting prior research, Study 1 demonstrated that self-reports of personal reputation were significantly related to peer report. In each study, political behavior was associated with decreased uncertainty and emotional exhaustion and increased job performance ratings for individuals with a favorable reputation. Conversely, political behavior predicted increased uncertainty and emotional exhaustion and decreased job performance ratings for individuals with an unfavorable reputation. Implications of these results, strengths and limitations, and directions for future research are discussed.     

What You Know When You Know an Answer to a Question

A significant argument for the claim that knowing‐wh is knowing‐that, implicit in much of the literature, including Stanley and Williamson (2001), is spelt out and challenged. The argument includes the assumption that a subject's state of knowing‐wh is constituted by their involvement in a relation with an answer to a question. And it involves the assumption that answers to questions are propositions or facts. One of Lawrence Powers’ counterexamples to the conjunction of these two assumptions is developed, responses to it are rebutted, and the possibility of rejecting the second rather than the first of these assumptions is explored briefly.     

Assembling an army: considerations for just war theory

The aim of this paper is to draw attention to an issue which has been largely overlooked in contemporary just war theory – namely the impact that the conditions under which an army is assembled are liable to have on the judgments that are made with respect to traditional principles of jus ad bellum and jus in bello. I argue that the way in which an army is assembled can significantly alter judgments regarding the justice of a war. In doing so, I present and defend a principle of ‘just assembly’ and argue that satisfying this principle is an essential part of any deliberation regarding the justice of a particular conflict.

The role of trainee knowledge structures in aviation team environments

The importance of having well-developed knowledge structures to enhance complex team performance has been recently indicated in the training effectiveness literature. This work tested that proposition within an aviation team training setting. Results suggested that aviation team training improved the knowledge structures of those participants who received the training. Knowledge structure data also provided information related to the training that was not available from more traditional measures of learning. Finally, results obtained from the knowledge structure measures were consistent with performance results, suggesting that knowledge structure measures are a potentially valid predictor of performance.     

Survival skills and ethics training for graduate students: A graduate student perspective

Graduate students in the sciences must develop practical skills geared toward scientific survival and success. This is particularly true now, given the paucity of research funds and jobs. Along with more elementary skills, research ethics should be an integral part of students’ scientific training. Survival skills include research skills, communication skills, general efficiency, and preparation for post-graduate work. Ethics training covers guidelines for use of animal and human subjects, data treatment, disclosure, credit issues, conflicts of interest, and response to misconduct. The objective of this paper is to describe, from a graduate student’s perspective, the need for survival and ethics training in graduate programs and to raise both faculty and student awareness of the possibilities for explicit instruction of these skills. Many survival skills and ethical practices will be learned without explicit direction and some are already part of standard training; but, this is not the case for all students or for all skills, so specific instruction is a necessity. Research faculty can use their own experience to help students to develop the proficiencies they will need to succeed.     

A new procedure for detection of crossing DIF

The purpose of this paper is to present a hypothesis testing and estimation procedure, Crossing SIBTEST, for detecting crossing DIF. Crossing DIF exists when the difference in the probabilities of a correct answer for the two examinee groups changes signs as ability level is varied. In item response theory terms, crossing DIF is indicated by two crossing item characteristic curves. Our new procedure, denoted as Crossing SIBTEST, first estimates the matching subtest score at which crossing occurs using least squares regression analysis. A Crossing SIBTEST statistic then is used to test the hypothesis of crossing DIF. The performance of Crossing SIBTEST is evaluated in this study.This research was partially supported by a grant from the Law School Admission Council and by National Science Foundation Mathematics Grant NSF-DMS-94-04327.
