Mothers' and Fathers' Psychological Symptoms and Marital Functioning: Examination of Direct and Interactive Links with Child Adjustment

A community sample of 51 mother-father dyads with a school-age child rated marital functioning, parental psychological symptoms, and children's adjustment problems. Parents with more psychological symptoms reported lower marital satisfaction levels. Mothers' and fathers' marital functioning and symptomatology individually related to children's adjustment in the expected directions. In addition, interaction tests revealed that, for mothers but not fathers, the combination of poorer marital functioning and higher levels of psychological symptoms amplified the negative effects on children's adjustment problems. These findings support the hypothesis that parental psychopathology and marital adjustment together affect children's functioning in an interactive way, underscoring the need to consider multiple family influences in studies of child development.     

Assessment of ADHD: differences across psychology specialty areas

Child psychologists are frequently involved in the assessment of ADHD symptoms among school-aged youth. There is limited information regarding the extent to which psychologists adhere to recommended assessment practices and whether differences exist in assessment strategies among psychologists from different specialty areas (clinical, counseling, and school) and/or who practice in different settings (university, school, or outpatient clinic). A 3 (specialty area) x 3 (employment setting) between-groups design is used wherein 230 child psychologists completed surveys regarding diagnostic practice. Psychologists differ in adherence with Diagnostic and Statistical Manual of Mental Disorders (4th ed., text revision) diagnostic criteria, use of clinical interviews, and type of behavior observation. Only 15% of psychologists report using multiple methods consistent with recommended standards of best practice. Differences between groups of psychologists indicate that the diagnosis of ADHD in children is influenced by the type of psychologist conducting the evaluation and the setting in which the evaluation is conducted.     

What counts as knowing? The development of conceptual and procedural knowledge of counting from kindergarten through Grade 2

The development of conceptual and procedural knowledge about counting was explored for children in kindergarten, Grade 1, and Grade 2 (N = 255). Conceptual knowledge was assessed by asking children to make judgments about three types of counts modeled by an animated frog: standard (correct) left-to-right counts, incorrect counts, and unusual counts. On incorrect counts, the frog violated the word-object correspondence principle. On unusual counts, the frog violated a conventional but inessential feature of counting, for example, starting in the middle of the array of objects. Procedural knowledge was assessed using speed and accuracy in counting objects. The patterns of change for procedural knowledge and conceptual knowledge were different. Counting speed and accuracy (procedural knowledge) improved with grade. In contrast, there was a curvilinear relation between conceptual knowledge and grade that was further moderated by children's numeration skills (as measured by a standardized test); the most skilled children gradually increased their acceptance of unusual counts over grade, whereas the least skilled children decreased their acceptance of these counts. These results have implications for studying conceptual and procedural knowledge about mathematics.     

Decomposing the problem-size effect: a comparison of response time distributions across cultures

Is the locus of the problem-size effect in mental arithmetic different across cultures? In a novel approach to this question, the ex-Gaussian distributional model was applied to response times for large (e.g., 8 x 9) and small (e.g., 2 x 3) problems obtained from Chinese and Canadian graduate students in a multiplication production task (LeFevre & Liu, 1997). The problem-size effect for the Chinese group occurred in mu (the mean of the normal component), whereas the problem-size effect for the Canadian group occurred in both mu and tau (the mean of the exponential component). The results support the position that the problem-size effect for the Chinese group is purely a memory-retrieval effect, whereas for the Canadian group, it is an effect of both retrieval and the use of nonretrieval solution procedures.     

SIDDS: Simulations in developmental disabilities

SIDDS, or simulations in developmental disabilities, is a computer system that provides students with the opportunity to acquire and practice skills in behavioral psychology. During the simulation, the student assumes the role of a psychologist whose professional duties involve the assessment and treatment of the severe problem behavior displayed by a child with a developmental handicap. Following an introduction to the use of the program, SIDDS guides the student/clinician through a series of steps involved in reducing a behavior problem. With the goal of eliminating the client’s behavior problem, the student/clinician proceeds through referral, problem identification, assessment, functional hypothesis, and treatment stages. This article describes the content and structure of SIDDS and provides a glimpse of what future developments of this system will entail.     

Do event-contingent diaries about marital conflict change marital interactions?

Recent increase in the use of diary measures has prompted questions about the effect completing diaries has on participants. After extensive training, married couples completed event-contingent diaries about their couple disagreements for 15 days, focusing on emotional and behavioral aspects of marital conflict. Serving as a control for placebo effects of participation, the diary group (n=110) and a non-randomized control group (n=57) also completed brief daily checklists, with minimal training, over the reporting period. Before and after the reporting period, couples engaged in videotaped conflict-resolution tasks that were coded for conflict behaviors and emotions expressed. ANOVAs comparing groups indicated that completing event-contingent diaries for 15 days had no apparent effects on observed husbands' and wives' expressed emotions and behaviors during marital interactions. Parental reports on the brief daily diaries indicated minimal differences between the groups in global measures of marital functioning. At the same time, husbands' self-reports in the home indicated decreasing perceptions of marital quality over the recording period. Thus, although no differences in conflict tactics emerged based on observed marital interactions in the laboratory, certain self-reports of responding suggested potential reactivity effects.     

Norms of subjective frequency of use and imagery for a sample of 1,916 French nouns.

Norms of rated subjective frequency of use and imagery on seven-point scales are reported for 1,916 French nouns. Subjective frequency was defined as the rated frequency of occurrence of words in spoken French, and imagery was defined as the rated case with which a word aroused a mental image. The mean, standard deviation, and percentile rank of the frequency and imagery ratings for each item are presented in the Appendix together with their objective frequency of occurrence in Baudot's (1992) dictionary. Interjudge reliability was assessed by calculating the correlation between the mean ratings of items repeated in the booklet, between the mean ratings obtained from odd-numbered and even-numbered respondents, and by computing the Cronbach alpha statistic for each page of the booklet. These reliability estimates were equal to or greater than .92 for frequency and for imagery, confirming the high level of interjudge consistency. Although the estimates provided by female and male participants were highly correlated (r = .97), the former gave a slightly higher frequency rating to the word sample but a slightly lower imagery rating than the latter did. Moreover, female respondents gave slightly more extreme ratings on the frequency and imagery scales. An analysis of the absolute difference between female and male ratings revealed a discrepancy of one half point or more on 20% of the word sample for frequency and 13% for imagery. On both scales, the mean absolute difference between male and female ratings was larger than that obtained by chance alone. This finding highlights the possibility that some words may not be equally familiar to women and men or may not evoke imagery with the same ease in these groups. Validity estimates for the frequency and imagery ratings were derived from correlations with scale values drawn from other normative studies. These correlation coefficients were equal to or greater than .78 for frequency and .86 for imagery, confirming the high level of consistency between this and other studies. An analysis of the relationship between subjective frequency and imagery ratings indicated that these variables are generally uncorrelated but exceptions occur. In the present study the coefficient of the correlation between subjective frequency and imagery was .24. However, when items with extreme mean frequency were excluded from the calculation, the correlation coefficient dropped to .04 and was no longer significant. Imagery ratings from five independent studies were all positively and significantly correlated with Vikis-Freibergs's (1974) frequency estimates, which were obtained from a free-association task. This finding suggests that word association, as a form of cued recall, may be influenced by several stimulus attributes including prior frequency of association and imagery-evoking value. The pattern of correlation between imagery ratings and text-based frequency estimates is not coherent. It reveals significant correlations only in select cases and no consistent polarity of linear relationship. The main contribution of this research is to provide reliable estimates of subjective frequency and imagery value for a word sample that is larger than those included in previous studies. A close examination of the linear relationship among the various sources of frequency and imagery data underscores the risk of confounding these variables in the selection of lexical stimuli for research.     

Children and Political Violence from a Social Ecological Perspective: Implications from Research on Children and Families in Northern Ireland

The effects on children of political violence are matters of international concern, with many negative effects well-documented. At the same time, relations between war, terrorism, or other forms of political violence and child development do not occur in a vacuum. The impact can be understood as related to changes in the communities, families and other social contexts in which children live, and in the psychological processes engaged by these social ecologies. To advance this process-oriented perspective, a social ecological model for the effects of political violence on children is advanced. This approach is illustrated by findings and methods from an ongoing research project on political violence and children in Northern Ireland. Aims of this project include both greater insight into this particular context for political violence and the provision of a template for study of the impact of children’s exposure to violence in other regions of the world. Accordingly, the applicability of this approach is considered for other social contexts, including (a) another area in the world with histories of political violence and (b) a context of community violence in the US.     

Children and marital conflict resolution: implications for emotional security and adjustment.

This study addresses multiple gaps in understanding the implications of marital conflict resolution for children. Mothers' diary home reports (N = 102 mothers, N = 578 reports) of marital conflict resolution (i.e., compromise, apology, submission, agreement to disagree, withdrawal) and of children's responses, along with the reactions of children (N = 163) to analogue presentations of the same conflict endings in the laboratory, were examined. The significance of specific marital conflict endings, including the emotionality of endings, was supported and demonstrated for the first time in the home. Parents' and children's appraisals of resolution were generally similar, although for some endings these appraisals differed, supporting the notion that children are sensitive to the broader implications of conflict endings for interparental relations and family functioning. Children's responses to conflict resolution were related to their broader adjustment, further indicating the significance of conflict endings to understanding the impact of marital conflict.
