Classroom behavior and children with mental retardation: Comparison of children with and without ADHD

Thirty-four children (ages 6–12 years) with moderate to borderline mental retardation were studied in a laboratory classroom setting to determine whether children identified as having attention deficit hyperactivity disorder on the basis of Conners Questionnaires differed in classroom behavior. Half of the children scored 15 or greater on both the Parent and Teacher Conners; the remaining children scored 11 or less. All were participants in a Saturday Education Program serving children with mental retardation. Direct observation of the laboratory classroom documented significant differences between groups on measures of on-task behavior and fidgetiness, especially during situations where little direct teacher feedback or supervision was available. Saturday Education Program staff, while blind as to group designation, rated the two groups as differing significantly on all scales of two standardized behavior problem checklists. Checklists by parents and teachers appear to be valid measures of classroom behavior of children with moderate to borderline mental retardation.This research was supported by a grant to the first author from the National Institutes of Child Health and Human Development, U.S. Department of Health and Human Services, grant No. 1R29HD26186-01A1.

Female and male intravenous drug users not-in-treatment: Are they at differential risk for AIDS?

We describe and compare the drug-use patterns of ethnically diverse (45% white, 39% African American, 15% Hispanic) female and male intravenous drug users (IVDUs) not-in-treatment. Focusing on a group of hard-to-reach and economically disadvantaged IVDUs, we were able to document drug use patterns and practices that have been shown to place them at increased risk for AIDS. We were also able to examine if women IVDUs were at differential risk for AIDS in comparison to men IVDUs. Results indicated that female IVDUs practices may place them differentially at risk for contracting HIV because they were more likely than male IVDUs to share needles. When female IVDUs shared needles, they were also more likely than male IVDUs to share needles with a spouse or sexual partner. We argue that these results may be tied to gender role socialization and have important implications for designing interventions for female IVDUs.This research was supported by Grant DA01070 from the National Institute on Drug Abuse to the second author.     

Psychopathology Following Interpersonal Violence: A Comparison of Risk Factors in Older and Younger Adults

A randomly selected sample of 549 women age 55 years and older and 2,669 women age 18–34 years was interviewed via telephone to determine prevalences of physical and sexual assault, posttraumatic stress disorder (PTSD) symptomatology, and depression. Prevalences of sexual and physical assaults were lower in older compared to younger women. In addition, given a trauma, prevalences and proportionate risk of posttraumatic psychopathology and depression were also lower for older, relative to younger women. Specifically, multivariate analyses revealed that sexual assault predicted only PTSD avoidance in older adults, but all forms of PTSD symptomatology and depression in younger adult women. Similarly, physical assault predicted only PTSD re-experiencing symptoms in older women, but all forms of PTSD symptoms and depression in younger women. Self-reported health status was not associated with any increased risk of psychopathology, and low income predicted increased avoidance and depression only in younger women.     

Gender Differences in Interest and Knowledge Acquisition: The United States,Taiwan, and Japan

The relationship between interest and knowledge was investigated in a representative sample of 11th grade students from cultures that differ in the strength of their gender-role stereotypes and their endorsement of effort-based versus interest-based learning. Among 11th graders from the United States (N = 1052), Taiwan (N = 1475), and Japan (N = 1119), boys preferred science, math, and sports, whereas girls preferred language arts, music, and art. General information scores were comparable across the three locations; however, boys consistently outscored girls. Gender and interest in science independently predicted general information scores, whereas gender and interest in math independently predicted mathematics scores. Cultural variations in the strength of the relationship between gender, interest, and scores indicate that specific socialization practices can minimize or exaggerate these gender differences.     

What's behind different kinds of kinds: effects of statistical density on learning and representation of categories

This research examined how differences in category structure affect category learning and category representation across points of development. The authors specifically focused on category density--or the proportion of category-relevant variance to the total variance. Results of Experiments 1-3 showed a clear dissociation between dense and sparse categories: Whereas dense categories were readily learned without supervision, learning of sparse categories required supervision. There were also developmental differences in how statistical density affected category representation. Although children represented both dense and sparse categories on the basis of the overall similarity (Experiment 4A), adults represented dense categories on the basis of similarity and represented sparse categories on the basis of the inclusion rule (Experiment 4B). The results support the notion that statistical structure interacts with the learning regime in their effects on category learning. In addition, these results elucidate important developmental differences in how categories are represented, which presents interesting challenges for theories of categorization.     

Mathematics Participation and Mathematics Achievement Across Secondary School: The Role of Gender

The present study investigated whether the relationship between mathematics participation and mathematics achievement is reciprocal for boys and girls. In Years 1, 2, 4 and 6 (US grades 7, 8, 10 and 12), we administered mathematics achievement tests to a cohort of 1,495 Flemish students and collected data on the number of classroom hours allocated to mathematics. A cross-lagged panel design was used to analyze the data. Evidence was found for a reciprocal relationship between mathematics participation and mathematics achievement, particularly in Years 4 and 6 (US grades 10 and 12). The results suggest that boys’ better performance in mathematics is related to their higher participation in math, whereas other factors—in addition to gender differences in math achievement—play a role in explaining why boys participate more in mathematics than girls.     

Emergence of syntax: commonalities and differences across children

This paper presents the results of a longitudinal examination of syntactic skills, starting at the age of emergence of simple sentences and continuing through the emergence of complex sentences. We ask whether there is systematic variability among children from different socioeconomic backgrounds in the early stages of sentence production. The results suggest a different answer for simple versus complex sentences. We found a striking similarity across SES groups on the measures tapping early mastery of basic syntactic rules of simple sentences. At the same time, there was a significant difference between SES groups in the mastery of complex sentence structures. This difference emerged at the earliest stages of production of multi-clause sentences and persisted throughout the period of observation. The implications of these findings for the understanding of mechanisms of syntactic development are discussed.     

Implementation and Utilization Characteristics of a Rural,School-linked Mental Health Program

We examined variables associated with treatment engagement in a real-world therapeutic setting. The model of care examined involved school-linked mental health care for children and their families in a rural county. Service utilization characteristics, as well as child- and treatment-specific variables were examined in relation to their impact on therapy length, missed appointments, and treatment outcome. A total of 168 students and their families participated in therapeutic services over a period of approximately 4.5 years. Overall, children who had less psychopathology and a higher level of clinician-rated functioning (GAF) at the start of therapy were more likely to successfully complete treatment. Parental involvement in therapy was associated with a longer course of therapy, as well as more missed appointments. Barriers to treatment and treatment engagement, as well as future directions of study, are discussed.     

Coping responses by adults who stutter: Part I. Protecting the self and others

Using a grounded theory approach, four clusters were identified that represent patterns of coping by adults who stutter. In order to understand the complexities within the coping responses of speakers to the experience of stuttering, this first of two companion papers summarizes the literature on the human coping response to stress and the nature of two of the four main findings identified. These findings describe a coping process that emphasizes strategies of protecting both the speaker and the listener from experiencing discomfort associated with stuttering. The companion paper describes the remaining two main findings that emphasize the characteristics of self-focused and action oriented coping responses.Educational Objectives: The reader will be able to: (1) describe, from the perspective of a select group of adults who stutter, the themes associated with the process of coping with stuttering, (2) describe the basic rationale for the procedures associated with grounded theory methods, (3) describe the factors that influence the choice to use emotion-focused and problem-focused coping strategies, and (4) explain the factors that contribute to the use of methods of escape.
