The social and communication impact of stuttering on adolescents and their families

Purpose

Stuttering can cause wide ranging psychosocial impact. This is particularly the case for adolescents who may face additional physical, emotional and personality changes as they become adults. This study reports the findings of an investigation into the social and communication impacts of stuttering on Australian adolescents seeking treatment for stuttering and their families.

Method

A cross-sectional design utilising questionnaires assessed the self-perceived communication competence and apprehension, stigma and disclosure, and experiences of teasing and bullying of 36 adolescents who stutter. Additionally, the impact of stuttering on the families of these adolescents was investigated.

Results

Adolescents who stutter have below average self-perceived communication competence, heightened communication apprehension, are teased and bullied more often than fluent peers, and they try to keep their stuttering secret. The families of the adolescents in the study reported high levels of emotional strain, family conflict and difficulty managing their child's frustrations.

Conclusion

The findings from this study emphasise the wide-ranging impact of stuttering beyond the surface level behaviours. Clinicians working with adolescents who stutter should take note of both the outcomes of this study and the suggestions for more effectively coping with the condition in this population.Educational objectives: The reader will be able to: (a) summarise findings with regards to the impact of stuttering on an adolescent's social and communication skills; (b) summarise areas of impact on the families of adolescents who stutter; (c) compare these findings with previous reported data for this population; (d) discuss the clinical implications of the results for working with adolescents who stutter and their families.     

Subculture Theory: An Historical and Contemporary Assessment of the Concept for Understanding Deviance

Subcultures attract attention in culture, society, and the media because they have been theorized as not merely distinct from, but also in opposition to, the dominant culture. In the United States and the United Kingdom the concept of subculture has been a major explanatory tool for sociology and criminology to understand deviant behavior. For nearly a hundred years the concept has been at the center of academic struggle for superiority between rival paradigmatic approaches, which have employed different theoretical explanations. In this article I critically assess the origins and politics of the way the concept of subculture has been applied primarily to youth cultures in terms of the relationship between agency and constraint.     

Optimism Is Universal: Exploring the Presence and Benefits of Optimism in a Representative Sample of the World

Current theories of optimism suggest that the tendency to maintain positive expectations for the future is an adaptive psychological resource associated with improved well‐being and physical health, but the majority of previous optimism research has been conducted in industrialized nations. The present study examined (a) whether optimism is universal, (b) what demographic factors predict optimism, and (c) whether optimism is consistently associated with improved subjective well‐being and perceived health worldwide. The present study used representative samples of 142 countries that together represent 95% of the world's population. The total sample of 150,048 individuals had a mean age of 38.28 (SD = 16.85) and approximately equal sex distribution (51.2% female). The relationships between optimism, subjective well‐being, and perceived health were examined using hierarchical linear modeling. Results indicated that most individuals and most countries worldwide are optimistic and that higher levels of optimism are associated with improved subjective well‐being and perceived health worldwide. The present study provides compelling evidence that optimism is a universal phenomenon and that the associations between optimism and improved psychological functioning are not limited to industrialized nations.     

Virtuous testimonial belief in young children

I lay out the challenge posed by testimonial knowledge in young children to virtue reliabilist accounts of knowledge. In particular, I examine accounts from Greco and Pritchard and argue that those accounts are too demanding. More specifically, I make the case that young children can have testimonial knowledge without meeting the ability requirements claimed by Greco and Pritchard. As a virtue theoretic alternative, I argue that an agent’s belief must be epistemically virtuous, but that this may sometimes involve belief from a trait rather than an ability.     

An evaluation of early and late stage attentional processing of positive and negative information in dysphoria

Depressive disorders may be characterised by hyperattention toward negative information, hypoattention toward positive information, or a combination of both processing biases. In two studies, a dot-probe task was utilised to better ascertain the specific direction and time-course of these biases. In both studies, the dysphoric group showed significantly less attentional allocation toward positive stimuli than the non-dysphoric group. In study two, the dysphoric group also showed greater attentional allocation toward depression-specific stimuli. Importantly, the bias toward depression-specific stimuli, and the bias away from positive stimuli, were uncorrelated with each other. It may be that both biases can act as sufficient, but not necessary, characteristics of dysphoric processing. An additional possibility is that the relative level of each bias type may best characterise dysphoric processing. Each of these possibilities is discussed in turn.     

Defensive copers show a deficit in passive avoidance learning on Newman's go/no-go task: implications for self-deception and socialization

The present study investigated whether passive avoidance learning was retarded by defensive coping strategies designed to minimize exposure to negatively valenced stimuli. High-anxious individuals, low-anxious individuals, and defensive copers completed a computerized go/no-go task, in which they learned when to press or not to press a button, in response to contingent positive and negative feedback. The duration that feedback remained onscreen was self-regulated. Defensive copers showed preferential reflection away from negative feedback, committed more passive-avoidance errors, and were characterized by impaired learning, overall. Further, the ratio of reflection on negative feedback to reflection on positive feedback directly mediated both passive-avoidance errors and overall learning. Defensive coping strategies, therefore, appear to interfere with passive avoidance learning, thereby fostering perseverative, dysfunctional action patterns by reducing knowledge gained from previous mistakes. Implications for the learning of effective socialization strategies, and for psychopathy-which is commonly characterized by similar passive-avoidance deficits-are subsequently considered.     

Preliminary evaluation of a 10-wk. resistance and cardiovascular exercise protocol on physiological and psychological measures for a sample of older women

A preliminary 10-wk. study was conducted to determine the effect a combined strength and cardiovascular exercise protocol had on both physiological and psychological change in 17 older (M age = 66.8 yr.), formerly sedentary women. The protocol was associated with better adherence than typically found for new and returning exercisers. Significant improvements over 10 wk. were found on Body Mass Index, body fat, resting heart rate, and balance. Significant, positive changes in mean ratings were also found on Physical Self-concept, Total Mood Disturbance, Depression, and Fatigue (small to moderate treatment effect sizes). Although no significant changes were found for rated Tension, Vigor, Anger, and Confusion, mean changes were in the desired direction and rated Tension showed a moderate effect size. The need for replication, including a control group and follow-up, plus continued research on exercise protocols both well-tolerated and effective for older individuals and other specific groups, were discussed.     

The influence of belief that a car crashed on witnesses' estimates of civilian and police car speed

The authors performed 2 experiments investigating the influence of the belief that a vehicle crashed on witnesses' estimates of the vehicle's speed. In Experiment 1, participants saw a video of a civilian car being driven, after which they were assigned to 1 of 2 conditions. The 1st group was told that the vehicle subsequently crashed; the 2nd group was not told that the vehicle crashed. The results indicted no differences between the 2 groups on a number of factors, including estimates of the vehicle's speed. Experiment 2 was identical except that the video showed a police car using flashing lights and sirens. Participants who had been told that the car had crashed overestimated speed, the likelihood of a crash, and the likelihood of someone being killed. Participants who were not told that the vehicle crashed estimated the speed of the vehicle accurately. Confidence in their estimates of speed was not significantly different between the 2 groups. Results are discussed with regard to police investigations of road accidents.     

Responding to persons with mental illnesses: police perspectives on specialized and traditional practices

Persons with mental illnesses increasingly come into contact with police in the community due to changes in local and national policies and police responsibility for maintaining order. Recently, specialized intervention strategies have been advanced to ensure that persons with mental illnesses are not inappropriately arrested and moved into the criminal justice system. This study builds on previous research undertaken on police perceptions of dealing with persons with mental illnesses in the community and effectiveness of response (see Borum et al., 1998). A subsample of 182 officers from the Newark, NJ, Police Department was surveyed and added to a sample of 452 officers from three agencies with specialized responses to persons with mental illnesses. The authors conclude that, despite a non-specialized response to this population, the actual and perceived effectiveness of Newark's strategy is similar to (and in some cases better than) that which is observed in the agencies with specialized response programs. Implications for implementing specialized responses for persons with mental illnesses are discussed.     

Finding the "genuine" schizotype: a model and method for resolving heterogeneity in performance on laboratory measures in experimental psychopathology research

Heterogeneity in the performance of persons affected with schizophrenia or schizotypic psychopathology on various laboratory tasks has long been recognized, both for its consistency across tasks and studies and for the massive methodological and substantive challenges it poses for experimental psychopathology, genetic, and other investigations. Traditional multivariate techniques, such as factor analysis, discriminant function analysis, and cluster analysis, have all been deemed inadequate for resolving heterogeneity, because of one or another statistical limitation. Here, an objective statistical approach based on a formal statistical model that uses the ubiquitous and well-developed expectation-maximization (EM) algorithm (A. P. Dempster, N. M. Laird, & D. B. Rubin, 1977) is presented, which enables one effectively to partition a group of experimental subjects, in this case identified initially using the well-known Perceptual Aberration Scale (L. J. Chapman, J. P. Chapman, & M. L. Raulin, 1978), in a manner that reduces heterogeneity and allows for the separation of what are termed genuine and false-positive schizotypes. The validity of the parsing strategy was supported by reference to other laboratory indexes of relevance to schizophrenia and schizotypy that were not included in the initial EM-based analyses. The potential utility of this approach is discussed with reference to future schizophrenia and schizotypy research.
