Voice acoustical measurement of the severity of major depression

A number of empirical studies have documented the relationship between quantifiable and objective acoustical measures of voice and speech, and clinical subjective ratings of severity of Major Depression. To further explore this relationship, speech samples were extracted from videotape recordings of structured interviews made during the administration of the 17-item Hamilton Depression Rating Scale (HDRS; ). Pilot data were obtained from seven subjects (five males, two females) from videotapes that have been used to train expert raters on the administration and scoring of the HDRS. Several speech samples were isolated for each subject and processed to obtain the acoustic measurements. Acoustic measures were selected on the basis that they were correlated with HDRS ratings of symptom severity as seen under ideal voice recording conditions in previous studies. Our findings corroborate earlier reports that speaking rate is well correlated (negatively) with HDRS scores, with a strong correlation and nearly significant trend seen for the measure of pitch variability. A moderate pairwise correlation between percent pause time and HDRS score was also revealed, although this relationship was not statistically significant. The results from this cross-sectional study further demonstrate the ability of voice and speech signal analyses to objectively track severity of depression. In the present case, it is suggested that this relationship is robust enough to be found despite the less than ideal recording conditions and equipment used during the original videotape recording. Voice acoustical analyses may provide a powerful compliment to the standard clinical interview for depression. Use of such measures increases the range of techniques that are available to explore the neurobiological substrates of Major Depression, its treatment, and the dynamic interplay of the systems that govern the motor, cognitive, and emotional aspects of speech production.     

"Frog, where are you?" Narratives in children with specific language impairment, early focal brain injury, and Williams syndrome

In this cross-population study, we use narratives as a context to investigate language development in children from 4 to 12 years of age from three experimental groups: children with early unilateral focal brain damage (FL; N=52); children with specific language impairment (SLI; N=44); children with Williams syndrome (WMS; N=36), and typically developing controls. We compare the developmental trajectories of these groups in the following domains: morphological errors, use of complex syntax, complexity of narrative structure, and types and frequency of evaluative devices. For the children with early unilateral brain damage, there is initial delay. However, by age 10, they are generally within the normal range of performance for all narrative measures. Interestingly, there are few, if any, side specific differences. Children with SLI, who have no frank neurological damage and show no cognitive impairment demonstrate significantly more delay on all morphosyntactic measures than the FL group. Quantitatively, on morphosyntactic measures, the SLI group clusters with those children with WMS who are moderately retarded. Together these data help us to understand the extent and nature of brain plasticity for language development and those aspects of language and discourse that are dissociable.     

Narrative Discourse in Children with Early Focal Brain Injury

Children with early brain damage, unlike adult stroke victims, often go on to develop nearly normal language. However, the route and extent of their linguistic development are still unclear, as is the relationship between lesion site and patterns of delay and recovery. Here we address these questions by examining narratives from children with early brain damage. Thirty children (ages 3;7–10;10) with pre- or perinatal unilateral focal brain damage and their matched controls participated in a storytelling task. Analyses focused on linguistic proficiency and narrative competence. Overall, children with brain damage scored significantly lower than their age-matched controls on both linguistic (morphological and syntactic) indices and those targeting broader narrative qualities. Rather than indicating that children with brain damage fully catch up, these data suggest that deficits in linguistic abilities reassert themselves as children face new linguistic challenges. Interestingly, after age 5, site of lesion does not appear to be a significant factor and the delays we have witnessed do not map onto the lesion profiles observed in adults with analogous brain injuries.     

The Influence of Indirect Knowledge of Previous Performance on Ratings of Present Performance: The Effects of Job Familiarity and Rater Training

In a 2 × 2 × 2 crossed factorial design, trained or untrained subjects viewed a videotape and evaluated performance on either a familiar (college lecturer) or unfamiliar (salesperson) job. Prior to viewing the videotape, some subjects reviewed positive information about the ratee's prior performance, whereas other subjects did not review any prior performance information. To determine whether assimilation or contrast effects occurred, we compared ratings provided by subjects who reviewed positive information about prior performance with ratings provided by subjects who did not review any prior performance information. A three-way interaction was obtained. Ratings of performance on the familiar job by untrained or trained subjects revealed only a small assimilation effect. However, when rating performance on the unfamiliar job, a large assimilation effect was observed among untrained subjects, whereas a large contrast effect was observed among trained subjects. The results indicate that rater error training may reverse, rather than reduce or eliminate, rating errors that arise from knowledge of a ratee's prior performance. Implications for further understanding and reducing assimilation and contrast effects are discussed.     

Politics and participation: Some antecedents of young people's attitudes to the political system and political activity

The antecedents of political disaffection and political activism have been extensively studied in adult populations, producing two models of political protest, the ‘dissatisfaction model’, suggesting that protest action is rooted in political disaffection, and the ‘resource model’ which bases interest in politics in a sense of political self-efficacy. There has been a dearth of research extending this theorizing to young people of prevoting age. The present study presents the results of regression analysis applied to longitudinal data collected in a U.K. Programme of research and economic and political socialization, the ESRC 16-19 Initiative. The analysis relates ‘lack of interest in politics’, ‘intention not to vote’ and ‘political activity’, to attitudes, personality characteristics, experience and circumstances measured earlier. It is concluded that political disaffection including lack of interest and intention not to vote, is strongly associated with a growing cynicism about politics rooted in poor educational performance and a working class family background. The connections with activism are negative but much weaker, suggesting the potential for protest activity across a wider spectrum of youth. This lends support to Marsh's (1990) view that given the right circumstances, protest action under both the ‘resource model’, and the ‘dissatisfaction model’, can apply.     

Analysis of systems influencing renal hemodynamics and sodium excretion. I. Biochemical systems theory

In this article we present a new methodology—Biochemical Systems Theory and Analysis—as an alternative to traditional parametric statistical procedures for investigating differences between risk groups in a population. We review the systems theory and how it can be used to represent a model of processes influencing renal hemodynamics and sodium (Na⁺) excretion. We also discuss the potential for new measures of the biology of common diseases that can emerge from a synergism between systems theory and population-based statistical approaches.

Family therapy training—give the customers what they want

Family therapy training is an area of current interest and debate within the Association for Family Therapy. At a local level regional groups and branches have been promoting family therapy through a variety of sources and events (Bott, 1979; Haldane, 1980). The development of training has therefore been of a haphazard and ad hoc nature. More recently the Sub-Committee on Training for Family Therapy has addressed itself to establishing and co-ordinating formalized training programmes and to the attendant issues of course structure, content and accreditation.
The Workshop at Bangor looked at the rationale behind and organization involved in setting up introductory training in family therapy. Several introductory training schemes already in operation throughout the U.K. were described and the results of a recent consumer survey conducted in Northern Ireland were presented.     

Choice freedom

Individuals seek and value choice freedom, firms provide consumers ever-increasing opportunities to exercise it, citizens worry about protecting their right to choose freely, and scholars across different disciplines study the topic around the globe. We adopt a consumer psychology perspective to systematize the vast literature on choice freedom, and we present a framework to examine the relationship between choice freedom and personal and societal well-being. We begin by proposing choice freedom as an antecedent of autonomy and personal control and by clarifying the meaning of these interrelated constructs. We then use autonomy and personal control as separate processes to explain benefits and limits of choice freedom for well-being, and we review interventions that mitigate the limits. Finally, we discuss future research questions related to autonomy and personal control. Whereas extant literature focuses on the presence of freedom and on the relationship between choice freedom and the individual, we reflect on the extent to which consumers actually have freedom of choice and on the role of others in the provision and exercise of choice freedom.     

Dynamic and Static Work-Family Relationships

This study investigated the linkages between work and family of 281 dual-employed couples. First, we developed a theoretical framework, distinguishing between the causal direction and the sign of the relationship between work and family. We classified the social and psychological mechanisms that explain specific directions and signs of work–family relationships and reviewed the empirical literature from the point of view of this framework. We then provided an illustration of how this framework can be used to generate a model for a specific sample. We generated a model and corresponding hypotheses for a sample of dual-employed couples in which the male′s career was dominant and analyzed these hypotheses by testing males and females separately using LISREL 7. In our sample, the relationship between work and family was reciprocal for males, suggesting a dynamic system in which males were able to adjust one domain to compensate for the other. Females exhibited a unidirectional relationship from family to work involvement, suggesting a static system. For both males and females, the family → work involvement relationship was negative as hypothesized. For males, the work → family relationship was positive. There were some similarities and some differences in the influence of exogenous constructs in the models for males and females. Results are discussed in terms of the importance of understanding dynamic versus static models of work and family relationships and the potential role of organizations in helping their employees lower the fixed demands of the family.
