The Writing Pal is an intelligent tutoring system that provides writing strategy training. A large part of its artificial intelligence resides in the natural language processing algorithms to assess essay quality and guide feedback to students. Because writing is often highly nuanced and subjective, the development of these algorithms must consider a broad array of linguistic, rhetorical, and contextual features. This study assesses the potential for computational indices to predict human ratings of essay quality. Past studies have demonstrated that linguistic indices related to lexical diversity, word frequency, and syntactic complexity are significant predictors of human judgments of essay quality but that indices of cohesion are not. The present study extends prior work by including a larger data sample and an expanded set of indices to assess new lexical, syntactic, cohesion, rhetorical, and reading ease indices. Three models were assessed. The model reported by McNamara, Crossley, and McCarthy (Written Communication 27:57-86, 2010) including three indices of lexical diversity, word frequency, and syntactic complexity accounted for only 6 % of the variance in the larger data set. A regression model including the full set of indices examined in prior studies of writing predicted 38 % of the variance in human scores of essay quality with 91 % adjacent accuracy (i.e., within 1 point). A regression model that also included new indices related to rhetoric and cohesion predicted 44 % of the variance with 94 % adjacent accuracy. The new indices increased accuracy but, more importantly, afford the means to provide more meaningful feedback in the context of a writing tutoring system.  相似文献

From the perspective of signal detection theory, different lineup instructions may induce different levels of response bias. If so, then collecting correct and false identification rates across different instructional conditions will trace out the receiver operating characteristic (ROC)—the same ROC that, theoretically, could also be traced out from a single instruction condition in which each eyewitness decision is accompanied by a confidence rating. We tested whether the two approaches do in fact yield the same ROC. Participants were assigned to a confidence rating condition or to an instructional biasing condition (liberal, neutral, unbiased, or conservative). After watching a video of a mock crime, participants were presented with instructions followed by a six‐person simultaneous photo lineup. The ROCs from both methods were similar, but they were not exactly the same. These findings have potentially important policy implications for how the legal system should go about controlling eyewitness response bias.Copyright © 2017 John Wiley & Sons, Ltd.  相似文献

This investigation examined relations between adolescent students' daily and cumulative perceptions of teachers' practice and their experience of autonomy. Two-hundred and eighteen high school science students in 43 classes participated in a 6-week diary study. Multilevel modeling results suggested that perceptions of 8 out of 9 practices predicted a change in students' daily autonomy. Results also revealed that autonomy-relevant practices interacted with time, each other, and characteristics of students and classrooms. Implications are discussed.  相似文献

A channel differentiator for brick-and-mortar retail stores is the availability of salespeople to assist customers directly in their purchase decision. This research considers two aspects of customer interactions with retail salespeople that lead to perceptions of extraordinary service and enhance repurchase intentions: customer comfort and salesperson expertise. Retail customers desire value-added informational assistance from the salesperson to minimize ambiguity associated with the product and to reduce the risk associated with a purchase decision. A retail salesperson needs to make customers feel comfortable so that the customer will share specific needs during the interaction, and the salesperson can recommend appropriate products and services. Our findings reveal that while both customer comfort and salesperson expertise positively influence satisfaction with the salesperson and customer delight, only customer delight leads to repurchase intentions. While satisfaction is a commonly asserted goal for retailers; the present research suggests that in a transaction-based environment, elevated emotions such as customer delight represent a more powerful predictor of repurchase intentions. This research provides evidence of trainable salesperson behaviors that enhance customer perceptions of extraordinary service and offer firms an opportunity for significant performance gains.  相似文献

Strategic Incremental Rehearsal (SIR) is a recently developed flashcard intervention that blends Traditional Drill with Incremental Rehearsal (IR) for teaching sight words. The initial study evaluating SIR found it was more effective than IR for teaching sight words to first-grade students. However, that study failed to assess efficiency, which is important to consider when evaluating and selecting interventions. Therefore, the current study evaluated both the efficiency and effectiveness of SIR compared with IR for teaching sight words to 4 general education students (3 in second grade and 1 in first grade) who were enrolled in 1 of 2 schools. An alternating treatments single-case design was used to compare the effects of SIR and IR interventions implemented 4 days per week across 4 or 5 weeks. Students’ accuracy with words that were introduced during the week was assessed on Fridays, and maintenance of these words was assessed the following Friday. Results indicated that both interventions were effective for teaching students sight words, but that SIR was slightly more effective and efficient than IR for 3 of the 4 students. Findings have implications for the selection of flashcard interventions for teaching sight word vocabulary to early elementary students.  相似文献

The present study evaluated the psychometric properties of the Spanish versions of the Perceived Religious Influence on Health Behavior scale and the Illness as Punishment for Sin scale in a sample of churchgoing Latina women (N = 404). For the Perceived Religious Influence on Health Behavior scale, confirmatory factor analysis provided support for the expected one-factor model, internal consistency reliability was good, and there was evidence of convergent validity. For the Illness as Punishment for Sin scale, confirmatory factor analysis provided support for the expected one-factor model, but on a revised seven-item version of the measure. Internal consistency reliability and convergent validity for this revised version were good. It is recommended that future studies use the Perceived Religious Influence on Health Behavior scale and the revised Illness as Punishment for Sin scale when examining these constructs among Latina women.  相似文献

In this article, we draw on our experiences as therapists and supervisors to highlight the errors new clinicians tend to make and how they can be avoided. A critical issue is how to approach the client's narrative. We propose a stance of “respectful skepticism,” in which the factors that shape the client's truth can best be appreciated. This represents a middle way between gullible listener and prosecuting attorney. We also discuss common problems with client motivation, as well as the changing role of feelings in therapy, the importance of the therapeutic contract, the high cost of defensiveness, the concept of conversational domains, and the advantages of avoiding therapeutic platitudes, explanatory fictions, and jargon.  相似文献

Given the preponderance of evidence supporting the efficacy of cognitive behavior therapy (CBT), there has been an increased emphasis on dissemination to community mental health systems (CMH). Trainers from two large-scale dissemination initiatives (n = 27) were surveyed regarding the common pitfalls and difficulties encountered by CMH clinicians learning CBT. Common pitfalls were organized according to the items of the Cognitive Therapy Rating Scale (CTRS; Young & Beck, 1980) and reviewed. Guided discovery was reported to be the most challenging CBT competency to learn. Qualitative methods were used to construct a grounded theory; trainer responses indicated they viewed the practice of CBT as not only a set of discrete skills, but also a way of thinking. Efforts may be needed to provide support, assistance, and resources to these CMH clinicians as they continue to build CBT competency.  相似文献

People expressed many different reactions to the events of September 11th, 2001. Some of these reactions were clearly negative, such as political intolerance, discrimination, and hate crimes directed toward targets that some, if not many, people associated with the attackers. Other reactions were more positive. For example, people responded by donating blood, increasing contributions of time and money to charity, and flying the American flag. The goal of this article is to review some of Americans' negative and positive reactions to 9/11. We also describe two frameworks, value protection and terror management theory, that provide insights into Americans' various reactions to the tragedy of 9/11.  相似文献
