Involuntary competence

This article addresses whether the state has the right to medicate involuntarily a defendant who is incompetent either to plead guilty or to stand trial for the purpose of restoring legal competence. It first presents the constitutional background concerning incompetence and the right of prisoners generally to refuse psychotropic medication. Then the article examines the individual and state interests that must be considered to decide specifically whether the state may involuntarily medicate a criminal defendant solely for the purpose of restoring competence. Although the individual interests are strong, the article contends that the state does have a right to medicate involuntarily defendants charged with most crimes to restore trial competence, and that adequate remedies are available to ensure that medicated defendants receive a fair trial.     

Decoding digit symbol: speed,memory, and visual scanning

The authors evaluated the relative contributions of speed, memory, and visual scanning to Digit Symbol score in a sample of young adults (N = 87). Speed (Symbol Copy) explained 35% of Digit Symbol variance; only half of this was attributable to graphomotor speed (Name Printing), implying a role for perceptual speed. Visual-scanning tests (e.g., Symbol Scan) explained (on average) 34% of Digit Symbol variance, much of which was independent of perceptual-motor speed, establishing an important role for visual-scanning efficiency in Digit Symbol performance. By contrast, memory tests (on average) explained only 4% to 5% of Digit Symbol variance: statistically significant but clearly subsidiary, although a visual memory composite correlated more strongly with Digit Symbol. The Digit Symbol incidental learning procedures did, however, correlate moderately with other memory measures, suggesting that they are valid memory screening devices.     

Cost-effectiveness and test-performance factors in relation to universal newborn hearing screening

The first portion of this paper reviews current understanding of the cost of universal newborn hearing screening (UNHS), including capital and operating expenses, as well as the costs for follow-up testing on infants who do not pass the hearing screening test in the perinatal period. Capital expenses include the cost of equipment. Operating expenses include the costs for disposables and personnel. Follow-up costs relate to the diagnostic testing that must be performed in order to determine hearing status in those infants who do not pass the newborn hearing screening test. This section is followed by a more theoretical approach, in which test performance, prevalence, program costs, and "costs of hearing loss" are combined in a model that includes all costs of hearing loss, including screening, follow-up testing, and costs (benefits) associated with identifying hearing loss early in life. While some of the model's cost/benefit assumptions may be incorrect, the general approach of taking into account both costs and benefits provides a framework for evaluating the utility of UNHS in a more global manner. Model assumptions (costs, benefits, prevalence, sensitivity, specificity) can be changed to values deemed more appropriate, but the general approach is still informative. With the present assumptions, it is shown that initially, the costs of UNHS exceed its benefits. However, after only four years of operation, UNHS programs will result in a net savings to society. These savings increase rapidly, reaching a maximum annual benefit of seven billion dollars 75 years after initiation of the program, which is also the societal benefit for all years thereafter.     

Generalized eta and omega squared statistics: measures of effect size for some common research designs

The editorial policies of several prominent educational and psychological journals require that researchers report some measure of effect size along with tests for statistical significance. In analysis of variance contexts, this requirement might be met by using eta squared or omega squared statistics. Current procedures for computing these measures of effect often do not consider the effect that design features of the study have on the size of these statistics. Because research-design features can have a large effect on the estimated proportion of explained variance, the use of partial eta or omega squared can be misleading. The present article provides formulas for computing generalized eta and omega squared statistics, which provide estimates of effect size that are comparable across a variety of research designs.     

Boredom proneness and sleep disorders as predictors of adult attention deficit scores

This study examined the extent to which boredom proneness and sleep disturbances were related to attention deficit scores in college-aged adults. In a sample of 148 college students, Attention scores on the Adult Behavior Checklist were best predicted by Boredom Proneness (BP) subscale scores, which assess one's inability to maintain internal stimulation and feelings of constraint, and scores on the Epworth Daytime Sleepiness Scale and Athens Insomnia Scale (R2 = .57). Hyperactivity scores were best predicted by the BP subscales, which assess one's need for a stimulating environment, the perception of time passing slowly, and feelings of constraint, and the Epworth Scale (R2 = .51). The findings contribute to the understanding of the symptomatology of attention deficit in adults and provide further evidence of the validity of this measure.     

Depression and Self-Esteem in Boys with Attention-Deficit/Hyperactivity Disorder: Associations with Comorbid Aggression and Explanatory Attributional Mechanisms

It was tested whether boys with attention-deficit/hyperactivity disorder (ADHD), subgrouped by aggressive status, would show higher rates of depressive symptomatology and lower levels of self-esteem than would comparison boys and, in a subsample, explored attributional mechanisms that may be related to such internalizing features. Study 1 utilized 114 boys with ADHD (all prior recipients of stimulant medication) and 87 comparison boys, aged 7–12 years. Aggressive boys with ADHD reported more symptoms of depression than did nonaggressive boys with ADHD, who, in turn, reported more depression than did comparison boys. Effect sizes were moderate to large and did not vary with a depression rating scale uncontaminated by ADHD-related items. For self-esteem, the most pronounced effect was that aggressive boys with ADHD showed lower levels than did nonaggressive ADHD or comparison boys; effects were again moderate to large. Study 2 participants were a subsample of boys with ADHD from Study 1 (N = 27). We probed causal attributions in ADHD-related domains through responses to hypothetical vignettes, in which the protagonist's medication status (medicated, not medicated) was crossed with type of outcome (good, bad). Medication-related attributions were frequent. In describing the protagonist's success in relation to medication treatment, the sample showed significant associations between (a) medication-related attributions and (b) increased depressive symptomatology as well as decreased self-esteem. We discuss attributional processes that may help to explain the variation in internalizing symptoms among children with ADHD.     

Patterns of acquisition in the emerging mental lexicon: the case of to and for in English.

A corpus analysis of 32 English-speaking children's first usages of the prepositions to and for (which have similar properties semantically and grammatically) was undertaken for the purpose of tracking intralexemic sense acquisition and lexical organization in an often neglected word class. The earliest senses used by these children do not reflect historical patterns of semantic extension. Diachronically, concrete, spatial, and semantically transparent usages emerged before more abstract, nonspatial, and opaque usages. Developmentally, frequency of use in the child's linguistic environment and co-occurrence in collocations with favored verbs or other useful expressions proved to be the major determinant of early production, suggesting that external rather than internal/cognitive factors play the major role in lexical development.     

Measuring Judgments of Professionals: Using Vignettes in a Social Survey About Patient Confusion

The use of a factorial survey to measure the clinical judgments of professionals is described. This design allows the researcher to partial out the effects of variables on clinical decision making while using probability sampling. Methods frequently used to study judgments are reviewed and a study of nurses' judgments about patients' confusional episodes are used to illustrate the application of the factorial survey. Acute confusion in patients is a common clinical problem for nurses working in medical-surgical units in acute care hospitals. Using the factorial survey to study a real-life problem such as confusion demonstrates how this design can be used to test judgments in complex clinical situations, to aid in concept development, and to identify consensus among professionals.
