Fluency disorders in genetic syndromes

The characteristics of various genetic syndromes have included “stuttering” as a primary symptom associated with that syndrome. Specifically, Down syndrome, fragile X syndrome, Prader-Willi syndrome, Tourette syndrome, Neurofibromatosis type I, and Turner syndrome all list “stuttering” as a characteristic of that syndrome. An extensive review of these syndromes indicated clients diagnosed with these syndromes do show evidence of nonfluency patterns, but not all would be considered stuttering. Many of the syndromes are marked by degrees of mental retardation that probably contribute to a higher than average prevalence of stuttering, as well as a higher than average prevalence of other fluency disorders (when compared to the population at large).

An in-depth analysis of the available data indicates that some of these genetic syndromes show patterns of stuttering that may be indicative of only that syndrome (or similar syndromes) that can be differentially diagnosed from developmental stuttering. Among these patterns are the word-final nonfluencies noted in Prader-Willi syndrome; the presence of stuttering in the absence of secondary behaviors noted in Prader-Willi syndrome and; the presence of palilalia, word-final and word-medial nonfluencies, and word-medial and word-final nonfluencies in Tourette syndrome. Implications for future research are discussed in light of these findings.

Educational objectives: The reader will be able to: (1) describe the various different genetic syndromes that are associated with fluency disorders; (2) describe the types of nonfluencies that are associated with the major types of genetic syndromes that have fluency disorders; (3) describe the behaviors that may assist in differentially diagnosing different types of speech characteristics associated with various genetic syndromes.     

Exercise commitment and proneness to eating disorders in a group of physical education teachers

The study examined the association of exercise commitment with proneness to eating disorders in 50 physical education teachers who had been practicing various aerobic sports at least three times a week for at least 5 years. Significant coefficients were found between Commitment to Exercise Scale scores, the number of weekly training sessions, and scores on the Eating Disorders Inventory-2 scales measuring Maturity Fears, Social Insecurity, Perfectionism, and Asceticism. However, no relationship was found between the Commitment to Exercise Scale and the Eating Disorders Inventory-2 variables measuring anorexic tendencies (such as Drive for Thinness, Body Dissatisfaction, and Bulimia). Findings suggest the presence of some psychological factors common to both anorexic tendencies and excessive exercising but not complete overlap, so a rather more complex pattern of relationships appears to be mediated by sex and personality characteristics.     

Fluency and fluency disorders: Their definition,measurement, and modification

Attempts at designing clinical procedures that would directly enhance fluency in disfluent speakers have been increased in the recent past. However, some of the basic problems relating to the definition, measurement, and modification of fluency and fluency disorders have not received much systematic attention. Some of these problems are examined in this article with a view to identify important research and clinical needs. Published studies on fluency therapy are also reviewed.     

Tolerance in a rigorous science

Scientists often evaluate other people's theories by the same standards they apply to their own work; it is as though scientists may believe that these criteria are independent of their own personal priorities and standards. As a result of this probably implicit belief, they sometimes may make less useful judgments than they otherwise might if they were able and willing to evaluate a specific theory at least partly in terms of the standards appropriate to that theory. Journal editors can play an especially constructive role in managing this diversity of standards and opinion.     

Fluency and Attitudes

The goal of this article is to review how, when, and why fluency, or processing ease, affects attitudes. The current article first defines fluency and then discusses its direct impact on attitudes, noting that fluency usually makes attitudes more positive and that it does so for a wide array of attitude objects. Mechanisms and moderators of these direct effects are also described. The article then summarizes how fluency can affect attitudes indirectly, through its impact on other judgments (like perceptions of confidence or truth) and on cognitive operations (like information processing). The article ends by highlighting a few areas where additional research is likely to reap impressive benefits.     

A Multinomial Model to Assess Fluency and Recollection in a Sequence Learning Task

We suggest that well-formedness judgements in conjunction with L.L. Jacoby's (1991) process dissociation procedure and an appropriate measurement model can be used to obtain measures of implicit and explicit sequence knowledge. We introduce a new measurement model designed specifically for the sequence learning task. The model assumes that sequence identification is based on recollection, perceptual or motor fluency, systematicity detection, and guessing. The model and the application of the process dissociation procedure were empirically evaluatedusing auditory eventsequences. In Experiment 1, the parameterreflecting recollection was higher in an intentional than in an incidental learning condition. Experiment 2 showed that random sequences interspersed among the systematic sequences during the acquisition phase may change this pattern of results. A manipulation of processing fluency in Experiment 3 was reflected in the appropriate model parameter. In sum, the new measurement model and the application of the process dissociation procedure appear to be useful tools in sequence learning research.     

Risk-factor research and prevention programs for anxiety disorders: a translational research framework

The aim of the present essay is to discuss the interconnection between risk-factor research and prevention program development for panic-spectrum psychopathology. We argue that prevention of panic-spectrum psychopathology specifically, and anxiety disorders more generally, is likely to be best advanced through active, systematic translation of basic, risk-factor research. After operationalizing key terminology, we present some exemplar risk-factor candidates for panic-spectrum psychopathology, summarize research related to their role as risk-factors for panic problems, and link this discussion to risk-factor nomenclature. We then present a translational framework for extrapolating extant knowledge on these and other potential risk-factors for panic-spectrum psychopathology with respect to the development of preventative interventions. The proposed translational framework is intended to describe a forward-feeding process by which risk-factor research could be used by clinical researchers to inform prevention programs; and reciprocally, how such prevention knowledge could be most effectively utilized to drive new, clinically focused risk-factor research.     

An Intervention Program to Increase Reading Fluency

Abstract

This study investigated the effects of a self-modeling/ self-monitoring intervention to increase oral reading fluency in 5 elementary school students. Initially, students were videotaped reading from grade-appropriate text. The videotape was then edited to create a self-modeling intervention tape of approximately 5-minutes in duration, depicting the students reading in a fluent manner. The edited videotape was shown back to the students on two occasions in order to initiate the self-modeling intervention. Following this, students were videotaped reading 1-minute reading passage probes and these videotapes, without editing, were then shown back to the students during each subsequent session. The videotapes were viewed by the students twice weekly for a period of 4 weeks. To promote self-monitoring, after each passage reading session students were provided with performance feedback in the form of words correct per minute (WCPM) and progress toward their long-term goal. Results indicated increases in growth of oral reading rate overtime with concomitant advances in instructional placement criteria.     

Using Percentile Schedules to Increase Academic Fluency

After a learner becomes accurate with a task, fluency must be shaped over time to reach the target goal. However, shaping criteria can be somewhat arbitrary; thus, an objective criteria has the potential to improve implementation consistency. One such method is through the use of percentile schedules. The purpose of the current study was to use a percentile schedule as a means of determining the reinforcement criterion to improve the fluency for three academic tasks. The participant was a 14‐year‐old boy diagnosed with developmental disabilities. The use of the percentile schedule based reinforcement criterion resulted in increased fluency with two of the three academic tasks. This study suggests that percentile schedules may provide an objective criterion for improving fluency. Copyright © 2016 John Wiley & Sons, Ltd.     

Managing organizational commitment: Insights from longitudinal research

This article summarizes what is known about the active management of affective organizational commitment (AOC) through a review of 58 studies employing longitudinal research designs. The review yields six broad categories of antecedents that have empirically demonstrated effects on AOC: socialization practices, organizational changes, human resource practices, interpersonal relations, employee–organizational relations, and a residual “other” category. Insights from the review include (a) that perceptions of personal attachment to the organization are among the most substantiated (but tenuous) strategies for enhancing AOC, (b) that theorizing and research efforts have focused almost exclusively on achieving high levels of AOC, and (c) organizations have been reticent to address situations when AOC is low. Implications and recommendations for the theoretical, research and practical advancement of AOC are offered.     

Civil commitment: A review of empirical research

This article presents a comprehensive review of empirical micro-level research which has attempted to evaluate changes in civil commitment law in the United States. It groups studies by category of the general question they address: Who are being processed through civil commitment and who are being committed? How dangerous are civil commitment candidates on admission, in the hospital, and after release? To what extent are court officers adhering to procedural protections in form and in intent? To what extent have restrictive criteria influenced the behavior of medical professionals in processing individuals through civil commitment? and What happens to individuals after their civil commitment experience and their involuntary hospitalization? The article points to needed research and concludes by summarizing existing research from the perspective of finding a balance between civil liverty and benevolence.     

Effects of a Multicomponent Intervention to Improve Reading Fluency in Adult Students

The purpose of the present study was to use a delayed multiple probe design to evaluate the effects of a multicomponent intervention on reading fluency in three adult Norwegian university students. Prior to the study, all the participants had below average reading speed and one had the diagnosis dyslexia. The present procedure consisted of reading support, fluency aim, repeated reading, performance feedback, and error correction. Training involved daily sessions where a passage was read four times in a session or until a predetermined fluency aim was reached. Each participant read 10 passages during the intervention. Maintenance, generalization, and reading comprehension were tested to evaluate characteristics of fluent performance. The main findings indicate that reading fluency of all the participants improved. Results are discussed with regard to (i) conducting a multicomponent intervention; (ii) maintenance of the achieved improvements; (iii) possible effects on reading comprehension; and (iv) social validity of the study.

Computers and commitment to a public management decision: An experiment

Based on results of an experiment, hypotheses are tested concerning the effects of computer use on decision commitment. The experiment required subjects to make an adoption decision regarding a hypothetical government agency's innovation. Subjects could choose from a variety of information sets, some computer based, some not, before making the decision. After their decision the subjects were given “new evidence” that contradicted their initial position. Two experimental treatments included more difficult access to the computer-based information and higher cost for the computer-based information. Results indicate that access difficulty diminishes confidence in decisions and leads to lesser commitment. However, the cost of the computer information seems to have little bearing on decision commitment.
