ABSTRACT We experimentally examine the effects of boilerplate disclosure and text markup on the judgments of novice and experienced users of financial information. We manipulate the presence of boilerplate (higher versus lower) and text markup (markup versus no markup) in sequential corporate disclosures, and examine participants' sensitivity to diagnostic information about the firm's financial performance. Using theory on the dilution effect, we predict that boilerplate will have a greater impact in the absence of markup, and markup's positive effect on sensitivity to diagnostic information will be stronger in disclosures with higher boilerplate. Our findings are consistent with this prediction. We also find that experienced users have greater sensitivity overall to diagnostic information and that markup increases novices' (but not experienced users') sensitivity to diagnostic information. Our findings extend theory on potential remedies to the dilution effect and are potentially useful to regulators as they consider improving the usefulness of corporate disclosure.

The purpose of this study was to evaluate parents' reactions and understanding of diagnostic information from written reports and conferences in a clinic which provides multidisciplinary evaluations for children with speech, learning, language, and hearing problems. Previous studies and anecdotal reports suggested that many parents do not receive appropriate diagnostic information about their children. In the present study questionnaires were mailed to parents who had received reports of evaluations and most of whom had attended hour-long conferences covering the findings. Questionnaires were also sent to professionals who had received reports. Fifty-seven percent of the parents, and 63% of the professionals returned the questionnaires. Ninety percent of the parents indicated that they had understood the results as they were presented in the conference. Ninety-three percent of the professionals and 89% of the parents stated they understood the conclusions of the written reports .Further, 83% of the parents and 80% of the professionals reported that the findings had made a change in the child's educational or medical treatment. The percentage of parents who reported understanding the findings was greater than expected. The specific informing techniques used in this study are discussed.

Purpose The purpose of this study is to examine the frequency and type of speech disfluencies (stuttering-like and nonstuttering-like) in bilingual Spanish–English (SE) children who stutter (CWS) to SE children who do not stutter (CWNS) during narrative samples elicited in Spanish and English to provide further diagnostic information for this population and preliminary data toward an expansion of this study. Method Participants included six bilingual SE children (three CWS, three CWNS) ranging in age from 5 years to 7;5 (years;months) and recruited from the surrounding Houston, Texas area. Participants provided a narrative sample in English and Spanish. The frequency of speech disfluencies was tabulated, and mean length of utterance was measured for each sample. Results Results indicate that both talker groups exceed the diagnostic criteria typically used for developmental stuttering. Regardless of the language being spoken, CWS participants had a frequency of stuttering-like speech disfluencies that met or exceeded the diagnostic criteria for developmental stuttering that is based on monolingual English speakers. The CWNS participants varied in meeting the criteria depending on the language being spoken, with one of the three CWNS exceeding the criteria in both languages and one exceeding the criteria for percentage of stuttering-like speech disfluencies in one language. Conclusion Findings from this study contribute to the development of more appropriate diagnostic criteria for bilingual SE-speaking children to aid in the reduction of misdiagnoses of stuttering in this population.

When a psychometric test has been completed by a number of examinees, an afterward analysis of required skills or attributes may improve the extraction of diagnostic information. Relying upon the retrospectively specified item-by-attribute matrix, such an investigation may be carried out by classifying examinees into latent classes, consisting of subsets of required attributes. Specifically, various cognitive diagnosis models may be applied to serve this purpose. In this article it is shown that the permission of all possible attribute combinations as latent classes can have an undesired effect in the classification process, and it is demonstrated how an appropriate elimination of specific classes may improve the classification results. As an easy example, the popular deterministic input, noisy “and” gate (DINA) model is applied to Tatsuoka’s famous fraction subtraction data, and results are compared to current discussions in the literature.
