We aimed to assess which comorbid problems (oppositional defiant behaviors, anxiety, autistic traits, motor coordination problems,
and reading problems) were most associated with Attention-Deficit/Hyperactivity Disorder (ADHD); to determine whether these
comorbid problems shared executive and motor problems on an endophenotype level with ADHD; and to determine whether executive
functioning (EF)—and motor-endophenotypes supported the hypothesis that ADHD with comorbid problems is a qualitatively different
phenotype than ADHD without comorbid problems. An EF—and a motor-endophenotype were formed based on nine neuropsychological
tasks administered to 816 children from ADHD—and control-families. Additional data on comorbid problems were gathered using
questionnaires. Results indicated that oppositional defiant behaviors appeared the most important comorbid problems of ADHD,
followed by autistic traits, and than followed by motor coordination problems, anxiety, and reading problems. Both the EF—and
motor-endophenotype were correlated and cross-correlated in siblings to autistic traits, motor coordination problems and reading
problems, suggesting ADHD and these comorbid problems may possibly share familial/genetic EF and motor deficits. No such results
were found for oppositional defiant behaviors and anxiety. ADHD in co-occurrence with comorbid problems may not be best seen
as a distinct subtype of ADHD, but further research is warranted.

Three questions are addressed concerning the relationship of Jewish identity to secular achievements. Are the secular achievements of American Jews related at all to the strength of their Jewish identity? Which has a stronger relationship to secular achievement, a religious or an ethnic Jewish identity? Do communal aspects or private, personal aspects of Jewish identity have the stronger relationship to secular achievements? Using the 2000–2001 National Jewish Population Survey, we find that educational attainment, labor force participation, and occupational achievements are related to several expressions of Jewish identity, even after controlling for the traditional sources of variation (age, gender, education, family status). Jewish identity, as expressed in terms of religion, ethnicity, communal commitment, and private attitudes and practices, is related to contemporary Jewish secular achievement, albeit differently for men and women. 相似文献

To test the relation between sluggish cognitive tempo (SCT) and DSM-IV ADHD symptoms, parent and teacher ratings of the 18 DSM-IV ADHD items and five potential SCT items were obtained in a community sample of 8-18 year-old twins that was overselected for ADHD and learning disabilities (n = 296). Confirmatory factor analyses revealed that a three-factor model provided the best fit to the data for both parent and teacher ratings. DSM-IV inattention and hyperactivity-impulsivity symptoms loaded on two factors consistent with the DSM-IV model, and five SCT symptoms loaded primarily on a third factor. The SCT and inattention factors were highly correlated, whereas SCT and hyperactivity-impulsivity were weakly related. Both raters indicated that children meeting symptom criteria for the combined and inattentive subtypes exhibited significantly more SCT symptoms than those meeting symptom criteria for hyperactive-impulsive type and the comparison group without ADHD. Children meeting symptom criteria for the inattentive type exhibited significantly more SCT symptoms than those meeting criteria for the combined type, based on teacher ratings. These results suggest that SCT is an internally consistent construct that is significantly associated with DSM-IV inattention. 相似文献

Examining the locus of age effects on complex span tasks 总被引:1,自引:0,他引:1
To investigate the locus of age effects on complex span tasks, the authors evaluated the contributions of working memory functions and processing speed. Age differences were found in measures of storage capacity, language processing speed, and lower level speed. Statistically controlling for each of these in hierarchical regressions substantially reduced, but did not eliminate, the complex span age effect. Accounting for lower level speed and storage, however, removed essentially the entire age effect, suggesting that both functions play important and independent roles. Additional evidence for the role of storage capacity was the absence of complex span age differences with span size calibrated to individual word span performance. Explanations for age differences based on inhibition and concurrent task performamce were not supported. 相似文献

While establishing a database that describes students' aggressive behaviors and the conditions present at the time of occurrence, we discovered a variety of definitions of aggression in the literature. This lack of consistency limits the information provided to teachers working with the frequent problem of violence. We propose an inclusive and verifiable definition of aggression gleaned from experience and the literature. The definition incorporates verbal, paraverbal, nonverbal, and physical aggression. Validation is presented from the literature, and from 39 practicing teachers who used the definition to categorize 659 target behaviors. The teachers' level of agreement with the authors' categorization was 93% (median). 相似文献

In a longitudinal study of 78 graduate business students, three aspects of career exploration—environment exploration, self-exploration, and the amount of information acquired—were examined as predictors of interview performance (interview rating and self-rating) and outcomes (call-back interviews and job offers). Environment exploration and the amount of information acquired related significantly with the recruiter's rating of interview performance and interview outcomes; self-exploration correlated with the recruiter's rating of interview performance. Interview readiness variables (perceived past performance, verbal persuasion, and feelings of self-efficacy) correlated modestly with career exploration variables, interview performance ratings, and interview outcomes. 相似文献

The present study was an attempt to determine the reliability and validity of an adapted vocational indecision scale designed for undergraduates (Osipow, S. H., Carney, C. G., Winer, J. L., Yanico, B. J., & Koschir, M., In Journal of Vocational Behavior, 1976, 9, 237) for use in a graduate student population. Internal consistency, test-retest, interrater reliability, and validity coefficients were calculated. A factor analysis and a multiple regression were also conducted. The findings suggest that the characteristics of the adapted indecision scale for the graduate students sample are similar to the characteristics of the unadapted instrument for the undergraduate sample in the S. H. Osipow, C. G. Carney, and A. Barak (Journal of Vocational Behavior, 1976, 9, 223–243) study. Potential therapeutic and research uses of the adapted indecision scale are also discussed. 相似文献

Six speech samples containing varying amounts of whole-word repetitions were tape-recorded and presented to 36 male and 36 female listeners. For each sample, listeners were asked to make judgments of fluent, disfluent, and stuttered speech, and to answer the question, “Would you recommend speech therapy?” Results showed that samples containing 5% or more word repetitions were not judged fluent speech by a majority of listeners. Judgments of disfluent and stuttered speech were nearly equal for speech samples containing word repetitions from 5% to 15%. At 20%, however, the judgments of stuttered speech were found to be more likely than judgments of disfluent speech. A majority of listeners recommended clinical services for speech samples containing 5% or more word repetitions. Generally, the results indicated that (1) the presence of whole-word repetitions is not normal regardless of frequency, (2) fluent speech may not contain 5% or more word repetitions, and (3) with 20% word repetitions the judgments of stuttering may be more likely than judgments of disfluency. 相似文献

This study used a between-subjects analysis of variance design (2 × 2 × 2 × 2) to estimate the effects of rater gender, ratee gender, the gender stereotype of the job, and the gender stereotype of the ratee's personal characteristics on a promotion decision. The results indicated that female employees with masculine characteristics were evaluated as most promotable regardless of the gender stereotype of the job or the gender of the rater. We also investigated the personal characteristics raters reported using in making their decisions. We asked raters to select ratee personal characteristics that most influenced their promotion decisions. Discriminant analyses showed that male and female raters approached the rating process differently and that it is predominantly the gender stereotype of the ratee's personal characteristics rather than the ratee's gender that influences the promotion process. 相似文献
