Fractal Characteristics of Response Time Variability

The relations between English spellings and pronunciations have been described as a fractal pattern. Manipulations of word properties are constructed to coincide with the fractal pattern of ambiguity in these relations (sampled as random variables). New word naming and lexical decision experiments replicate previously established effects of relations between word spellings and pronunciations. The structure of these relations establishes a measurement scale, which is nested in a manner that is loosely analogous to the way that centimeters are nested within meters, and so on. The experiments revealed that broader, increasingly stretched-more variable-distributions of pronunciation and response time accompany the introduction of higher resolution measurement scales to the naming and lexical decision measurement process. Moreover, the distribution of lexical decision response times is shown to obey an inverse power-law scaling relation, which implies lexical decision does not conform to a characteristic measurement scale.     

Recovering faces from memory: the distracting influence of external facial features

Recognition memory for unfamiliar faces is facilitated when contextual cues (e.g., head pose, background environment, hair and clothing) are consistent between study and test. By contrast, inconsistencies in external features, especially hair, promote errors in unfamiliar face-matching tasks. For the construction of facial composites, as carried out by witnesses and victims of crime, the role of external features (hair, ears, and neck) is less clear, although research does suggest their involvement. Here, over three experiments, we investigate the impact of external features for recovering facial memories using a modern, recognition-based composite system, EvoFIT. Participant-constructors inspected an unfamiliar target face and, one day later, repeatedly selected items from arrays of whole faces, with "breeding," to "evolve" a composite with EvoFIT; further participants (evaluators) named the resulting composites. In Experiment 1, the important internal-features (eyes, brows, nose, and mouth) were constructed more identifiably when the visual presence of external features was decreased by Gaussian blur during construction: higher blur yielded more identifiable internal-features. In Experiment 2, increasing the visible extent of external features (to match the target's) in the presented face-arrays also improved internal-features quality, although less so than when external features were masked throughout construction. Experiment 3 demonstrated that masking external-features promoted substantially more identifiable images than using the previous method of blurring external-features. Overall, the research indicates that external features are a distractive rather than a beneficial cue for face construction; the results also provide a much better method to construct composites, one that should dramatically increase identification of offenders.     

Revisiting the Local Impact of Community Indicators Projects: Sustainable Seattle as Prophet in Its Own Land

Sustainable Seattle’s Indicators of Sustainable Community project was the first of its kind and remains one of the best known attempts by a community group to measure a wide range of what it values most about local quality of life and sustainability. The great irony in the organization’s notoriety, however, is that S2’s reputation grows with distance from its home in Seattle. National and international recognition has come to S2 much more easily than uptake and implementation of the project, its method, or its recommendations at home in Seattle and King County. This article, based on case study research, provides a closer examination of this received wisdom about the limited local impact of Sustainable Seattle by foregrounding the local legacy of this first generation indicators project in the form of nine different indicator projects that have succeeded the S2 project. All of these projects bear some connection to S2 and can be shown to constitute second, third and fourth generation indicator projects in terms of organizational structure, indicator framework, and approach to mobilizing awareness and policy and behavioural change. This article also offers lessons from indicator projects in the Seattle area about the appeal of an indicators-based approach generally, and the various Seattle models in particular, from the perspective of different key policy actor groups. In sum, the research presented in this article contributes to filling the gap in the community indicators literature with regard to the policy impacts of community indicator projects in their localities and directions for increasing the effectiveness of projects from the perspectives of different indicator organizations and policy actor groups.     

Structured personality test item characteristics and validity

Using the structured personality test item as the unit of analysis, the purpose of this research was to evaluate the relationship between validity and a variety of other test item parameters. Of particular interest was the relationship of test item criterion validity to negative keying and to negative wording. By drawing a distinction between negative keying and negative wording it was demonstrated that the use of balanced scales to control acquiescence need not result in a reduction in item criterion validity. Whereas the use of negative wording has in the past reduced validity, data demonstrated that positively worded, negatively keyed items did not. In addition, results indicated that clear, moderately short, relevant test items tended to be the most empirically valid.     

Estimating rates of chronic fatigue syndrome from a community-based sample: A pilot study

Most of the Chronic Fatigue Syndrome (CFS) epidemiological studies have relied on physicians who refer patients having at least 6 months of chronic fatigue and other symptoms. However, there are a number of potential problems when using this method to derive prevalence statistics. For example, some individuals with CFS might not have the economic resources to access medical care. Other individuals with CFS might be reluctant to use medical personnel, particularly if they have encountered physicians skeptical of the authenticity of their illness. In addition, physicians that are skeptical of the existence of CFS might not identify cases. In the present pilot study, a random community sample (N=1,031) was interviewed by telephone in order to identify and comprehensively evaluate individuals with symptoms of CFS and those who self-report having CFS. Different definitions of CFS were employed, and higher rates (0.2%) of CFS were found than in previous studies. Methodological benefits in using more rigorous epidemiological methods when estimating CFS prevalence rates are discussed. The authors appreciate the generous financial support of the CFIDS Association and Minnan, Inc. We also are grateful for many helpful suggestions provided by Judith A. Richman, William McCready, Wendell Richmond, and Stephen E. Goldston.

The Effect of Racial and Ethnic Diversity on the Delivery of Mental Health Services in Pediatric Primary Care

The effects of racial and ethnic diversity on the detection and management of behavioral and emotional problems in pediatric primary care are addressed. Service access and utilization as a function of race and culture are initially examined. Important barriers within pediatric training including minimal emphases on behavioral training and the limited supply of minority physicians are underscored. The impact of ethnicity on the development and maintenance of the clinical relationship that is critical to accurately and sensitively identifying and managing behavioral and developmental problems is briefly addressed. Recommendations for further integration of racial/ethnic issues into mental health service provision within the pediatric primary care arena are presented.     

The Impact of Gender on Productivity and Satisfaction Among Medical School Psychologists

The impact of gender on productivity and satisfaction was examined among a random sample of 293 psychologists employed as faculty members in medical schools. Forty-one percent of the respondents were female. Males were older than females, had worked in a medical school longer, had higher academic ranks, held more administrative positions, were more likely to be tenured, and earned higher salaries. When years of employment as a psychologist were statistically controlled, there were no gender differences in productivity, as measured by publications, presentations, and grant awards; however, gender differences in salary remained. Females were less satisfied than males with regard to salary, promotion opportunities, and overall respect. Results are discussed within the context of the changing gender composition within psychology and the changing demands within the health care system.     

Disclosure of Trauma and Psychosomatic Health: An Interview With James W. Pennebaker

This interview with James W. Pennebaker explores the often serendipitous career development of his interest in the relationship between the disclosure or inhibition of traumatic experience and psychosomatic illness. His current research has moved beyond psychosomatic illness to address other aspects of physical and mental health. The importance of Pennebaker's research is reflected in the many books and articles he has written, the continuing grants he has procured, and the awards he has won. His research findings yield several important implications for the counseling process and for counseling professionals themselves.
