Is there a temporal basis of the word length effect? A response to Service (1998)

Service (1998) carried out a study of the word length effect with Finnish pseudowords in which short and long pseudowords were identical except for the inclusion of certain phonemes differing only in pronunciation length, a manipulation that is impossible in English. She obtained an effect of phonemic complexity but little or no word duration effect per se - a discrepancy from the expectations generated by the well-known working memory model of Baddeley (1986). In the present study using English words, we controlled for phonemic complexity differences by using the same words for the short- and long-word sets, but with instructions inducing shorter or longer pronunciation of the words. We obtained substantial word duration effects. Concerns raised by Service are addressed, and we conclude that both duration and complexity are likely to contribute to the word length effect in serial recall.     

SIMPLIFIED HABIT REVERSAL TREATMENT FOR CHRONIC HAIR PULLING IN THREE ADOLESCENTS: A CLINICAL REPLICATION WITH DIRECT OBSERVATION

Three developmentally normal adolescents with chronic hair pulling were treated with a simplified habit reversal procedure consisting of awareness training, competing response training, and social support. Treatment resulted in an immediate reduction to near-zero levels of hair pulling, with one to three booster sessions required to maintain these levels. The results were maintained from 18 to 27 weeks posttreatment, although 1 participant reported difficulty at follow-up. The effectiveness of simplified habit reversal and suggestions for future research are discussed.     

Exploring the edges: boundaries and breaks

In this article, we examine conceptual and practical issues pertaining to relationship boundaries within the helping profession. Although our focus is primarily on relationships between mental health professionals and clients, there are considerable implications for a new approach to ethically structuring and understanding the construct of "required distance" in many human-interactive professions, such as teaching, religious leadership, public administration, and others. We define the concept of boundary as applied to human relationships, provide examples of boundary breaks, and raise questions regarding how to evaluate the significance and morality issues raised by specific boundary breaks. Questions and dilemmas are presented regarding boundary setting and accidental or deliberate boundary breaking. Representative dangers present in boundary breaks are identified, and examples are provided. Possible beneficial outcomes are also discussed. Finally, a suggested protocol for assessing a proposed boundary break is provided, much of which is drawn from the work and thinking of Laura Brown, applied more generally in this article, with additions from our perspectives.     

CAT: A tool for eliciting knowledge on how to perform procedures

Procedural tasks involve context-sensitive sequences of actions that are performed in pursuit of goals. Procedural knowledge specifies how to do something (e.g., repairing a car) but not how the physical system works (e.g., how the engine works). We have developed a computer program that elicits procedural knowledge from individuals with varying amounts of domain knowledge (ranging from novices to experts) and varying amounts of computer literacy. The tool is called CAT (cognitive analysis tool). CAT is an extension of a class of cognitive models known as GOMS, which stands for goals, operators, methods, and selection rules. The tool guides the user in articulating the goals (and subgoals) the user wants to accomplish, the operators (actions, steps) to accomplish each goal, the alternative methods of accomplishing goals, the conditions in which each method is applied, and exceptional circumstances when goals are suspended and restarted. CAT can be used on most IBMcompatible microcomputers.     

Sensitivity to sucrose in smokers and nonsmokers: A comparison of TSD and percent correct measures

Ten smokers and 10 nonsmokers were compared for taste sensitivity to sucrose on two discrimination tasks, one at near-threshold (NT) concentration level and one at suprathreshold (ST) concentration level. The data were analyzed using the d_s and area under ROC curve measures based on the theory of signal detection (TSD). and by using the percentage correct responses. Analysis of both TSD measures showed smokers to be significantly more sensitive than nonsmokers on the NT .task and more sensitive on the ST task, but not significantly so. Comparison of mean percent correct responses showed no significant differences. A reflexive enhancement phenomenon was suggested as a possible interpretation. A decreased sensitivity to the bitter taste in smokers apparently results in an increased sensitivity to the sweet taste.     

Case Report: Direct Access Genetic Testing and A False-Positive Result For Long QT Syndrome

We report the case of a woman who pursued direct access genetic testing and then presented with concerns regarding a positive test result for Long-QT syndrome. Although the result ultimately proved to be a false positive, this case illustrates that costs associated with follow-up of direct access genetic testing results can be non-trivial for both the patient and for health care systems. Here we raise policy questions regarding the appropriate distribution of these costs. We also discuss the possibility that, when confronted by a direct access genetic test result that reports high risk for one or more actionable diseases, a family physician might feel compelled to act out of a desire to avoid liability, even when information regarding the accuracy and validity of the testing were not easily accessible. This case outlines lessons that can easily be translated into clinical practice, not only by genetic counselors, but also by family physicians, medical specialists and members of the public.     

Forum: Insiders,Outsiders, and Disclosure in the Undergraduate Classroom

In this set of essays, three authors provide different perspectives on whether personal religious sensibilities and identities affect the ways we teach religion. Elliott Bazzano discusses how, as a white Muslim convert teaching at a Catholic college, he incorporates selective autobiographical anecdotes into his classes as a way to problematize the meaning of “insider” and “outsider,” and pushes his students to recognize the many layers of identity that any given person embodies at a given time. In the second essay, Audrey Truschke explains why she makes no reference to her own religious beliefs or affiliations in class as part of her strategy to demonstrate how students can study any religion regardless of personal convictions. In the third essay, Jayme Yeo explores the benefits of discussing personal religious identity as a means to resist the categories of “inside” and “outside,” which she sees as heterogeneous concepts that do not always offer explanatory power upon close examination.     

Zhuangzi and Buber in Dialogue: A Lesson in Practicing Integrative Philosophy

I put forward the case that comparative philosophy is best practiced as integrative philosophy. The model for integrative philosophy employed embodies its own methodology, integrating the Hegelian dialectic and the Yin-Yang 陰陽, cyclical model of change illustrated by the Yijing 易經 (Book of Changes) as strategies for integrating philosophical traditions. As an object lesson, I integrate a real, historical one-way encounter with an imagined two-way encounter between Martin Buber and Zhuangzi 莊子, to provide a counter-example to replace Huntington’s clash of civilizations with a meeting of civilizations.     

An evaluation of multi‐criteria methods in integrated assessment of climate policy

Those who conduct integrated assessments (IAs) are aware of the need to explicitly consider multiple criteria and uncertainties when evaluating policies for preventing global warming. MCDM methods are potentially useful for understanding tradeoffs and evaluating risks associated with climate policy alternatives. A difficulty facing potential MCDM users is the wide range of different techniques that have been proposed, each with distinct advantages. Methods differ in terms of validity, ease of use, and appropriateness to the problem. Alternative methods also can yield strikingly different rankings of alternatives. A workshop was held in which climate change experts and policy makers evaluated the usefulness of MCDM for IA. Participants applied several methods in the context of a hypothetical greenhouse gas policy decision. Methods compared include value and utility functions, goal programming, ELECTRE, fuzzy sets, stochastic dominance, min max regret, and several weight selection methods. Ranges, rather than point estimates, were provided for some questions to incorporate imprecision regarding weights. Additionally, several visualization methods for both deterministic and uncertain cases were used and evaluated. Analysis of method results and participant feedback through questionnaires and discussion provide the basis for conclusions regarding the use of MCDM methods for climate change policy and IA analyses. Hypotheses are examined concerning predictive and convergent validity of methods, existence of splitting bias among experts, perceived ability of methods to aid decision‐making, and whether expressing imprecision can change ranking results. Because participants gained from viewing a problem from several perspectives and results from different methods often significantly differed, it appears worthwhile to apply several MCDM methods to increase user confidence and insight. The participants themselves recommended such multimethod approaches for policymaking. Yet they preferred the freedom of unaided decision‐making most of all, challenging the MCDM community to create transparent methods that permit maximum user control.
