Temporal processing and phonological impairment in dyslexia: effect of phoneme lengthening on order judgment of two consonants

The evidence of supporting phonological deficit as a cause of developmental dyslexia has been accumulating rapidly over the past 2 decades, yet the exact mechanisms underlying this deficit remain controversial. Some authors assume that a temporal processing deficit is the source of the phonological disorder observed in dyslexic children. Others maintain that the phonological deficit in dyslexia is basically linguistic, not acoustic, in nature. Three experiments were conducted and tested the impact of the temporal alteration and the impact of complex syllabic structure on consonant order judgments. Thirteen phonological dyslexics (age 10-13) and 10 controls matched for chronologial age were compared on a Temporal Order Judgment (TOJ) task using the succession of two consonants (/p/ /s/) within a cluster. In order to test the possible relevance of the temporal deficit hypothesis, the task also included two additional conditions where either the two stimuli were artificially slowed or two phonological structures were opposed (CCV and CVCV). As expected, the TOJ performance was significantly poorer in dyslexics than in controls. Moreover, in the "slowed speech" condition dyslexics' performance improved to reach the normal controls' level, whereas manipulating the phonological structure complexity provided no significant improvement. Finally dyslexics' performances, especially on the slowed condition, were found correlated with several tests of phonological processing. These results lend support to the general temporal deficit theory of dyslexia.     

Labeling and the Adoption of a Deviant Status

This study explores the role of labeling in the process by which individuals come to perceive their personal indebtedness as indicative of a deviant status. Particular attention is paid to the respective roles one's informal social network and self-help groups play in promoting the transformation from a non-deviant to deviant status. In-depth interviews with a convenience and snowball sample of 46 members of Debtors Anonymous (DA), was supplemented with contextual data from a DA newsletter and other print materials. The theoretical implications for both labeling theory and identity change processes are discussed.     

Using integrated theory to explain the movement into juvenile delinquency

Research grounded in labeling, differential association, social learning, and social control theory provides useful information about various phases of the delinquency process. However, none of these theories accounts for the entire delinquency process. Recent work has demonstrated, for example, that social control theory may be more suitable for explaining initial delinquency, whereas labeling theory is more useful in explaining continued delinquency. This paper incorporates theoretical elements of labeling, differential association, social learning, and social control theories into a model that explains both initial and continued delinquency. Analysis of data from three waves of the National Youth Survey provides support for the model and shows that weakened social controls increase opportunities for associating with delinquent peers, learning delinquent behaviors, and committing initial delinquent acts. Initial delinquency increases the likelihood of being observed and negatively labeled by parents. These labels in turn increase the likelihood of future delinquency. These results lend support to arguments for integrated theory in the study of juvenile delinquency.     

Dyadic Versus Individual Storytelling by Preschool Children

A constructive model of recall and communication (D. Edwards & D. Middleton, 1986) and certain whole-word approaches to learning (C. Pontecorvo & C. Zucchermaglio, 1989) were evaluated in conjunction with an investigation of the benefits of joint storytelling on children's cognitive processes. Preschoolers (N = 36, aged 30-62 months) were prompted to compose a story, working with a classmate (during which they talked together freely and generated a mutual narrative) or individually. Findings revealed that, although dyadically generated stones were longer, containing significantly more words, propositions, and additive conjunctions, stories told by individuals contained proportionally more logically connected statements and greater use of the past tense. Moreover, compared with dyadic stories, individually generated narratives contained fewer alterations of the protagonist.     

Representational momentum when attention is divided

Observers tend to misremember a transforming object's final appearance as further along in the direction of continued transformation. This forward bias, termed representational momentum (RM), suggests that the dynamics associated with an object cannot be ignored in the effort to remember a particular instance of the object. Two experiments tested how attentional focus affects this memory bias. Observers attended to one object, divided attention across more than one object, or performed a secondary task simultaneously with the RM task. For objects translating in space, diminished attention increased the forward memory shift, suggesting that under distraction, motion can be represented but the stopping point is less effectively represented. We propose that object dynamics are well represented when attention is distracted, but that representing a change—including stopping—in the dynamics requires attention. We suggest some experiments to examine this proposal further.     

Integrated Schooling and Religious Tolerance in Northern Ireland

The design of educational institutions has long been seen as a key element in determining social divisions. This article examines the long-term impact of separate and integrated education on relations between the two religious communities (Catholics and Protestants) in Northern Ireland. Using a large-scale survey, the results suggest that in comparison to their previously separate counterparts, individuals who attended an integrated school are more likely to be understanding and respectful of the culture and traditions of others. The finding holds even after a range of background characteristics are taken into account. The results have implications for the role of segregated educational institutions in ameliorating religious, ethnic or racial division in other post-conflict societies. The Northern Ireland evidence suggests that a segregated school system rather than ameliorating intolerance and division may end up exacerbating and reinforcing it.     

Two Concepts or Two Approaches? A Bifactor Analysis of Psychological and Subjective Well-Being

Researchers often debate about whether there is a meaningful differentiation between psychological well-being and subjective well-being. One view argues that psychological and subjective well-being are distinct dimensions, whereas another view proposes that they are different perspectives on the same general construct and thus are more similar than different. The purpose of this investigation was to examine these two competing views by using a statistical approach, the bifactor model, that allows for an examination of the common variance shared by the two types of well-being and the unique variance specific to each. In one college sample and one nationally representative sample, the bifactor model revealed a strong general factor, which captures the common ground shared by the measures of psychological well-being and subjective well-being. The bifactor model also revealed four specific factors of psychological well-being and three specific factors of subjective well-being, after partialling out the general well-being factor. We further examined the relations of the specific factors of psychological and subjective well-being to external measures. The specific factors demonstrated incremental predictive power, independent of the general well-being factor. These results suggest that psychological well-being and subjective well-being are strongly related at the general construct level, but their individual components are distinct once their overlap with the general construct of well-being is partialled out. The findings thus indicate that both perspectives have merit, depending on the level of analysis.     

The Advantages of Predictive Interval Forecasts for Non‐Expert Users and the Impact of Visualizations

Three experiments demonstrated advantages over conventional deterministic forecasts for participants making temperature estimates and precautionary decisions with predictive interval weather forecasts showing the upper and lower boundaries within which the observed value is expected with a specified probability. Participants using predictive intervals were better able to identify unreliable forecasts, expected a narrower range of outcomes, and were more decisive than were participants using deterministic forecasts. Predictive interval format was also manipulated to determine whether adding visualizations enhanced understanding. Some participants using visualizations misinterpreted predictive intervals as expressions of diurnal fluctuations (deterministic forecasts). Almost no misinterpretations occurred when the predictive interval was expressed in text alone. Moreover, no advantages were found for visualizations over text‐only formats, demonstrating that visualizations, especially those investigated in these studies, may not be suitable for expressing this concept. Thus, predictive intervals are both understandable and advantageous to non‐expert decision makers, as long as they are carefully expressed. Copyright © 2013 John Wiley & Sons, Ltd.     

Targeting Self-Stigma in Returning Military Personnel and Veterans: A Review of Intervention Strategies

Research suggests that mental health-related stigma significantly decreases the use of mental health services by military personnel and veterans. The goal of this article is to review what is known about mental health stigma as it relates to military personnel and veterans, as well as to offer an interpretive review of self-stigma intervention strategies that have been applied within the field. Target areas for future work and the concerns and challenges faced by interventionists are discussed.
