A teacher scale based on DSM-III-R diagnostic criteria for attention deficit hyperactivity disorder (ADHD) was developed for the behavioral assessment of children in Brazil. A total of 2, 082 children (782 males and 1,300 females) with a mean age of 11.2 years who were attending a public school in the greater Rio de Janeiro area were the subjects of this study. Two factors (Hyperactivity-Impulsivity and Inattention) were extracted from a principal-factor analysis conducted on the data, and the factor structure of the scale was found to be stable. Ratings of boys were higher than ratings of girls, and younger children had higher ratings than older children for both factors. Test-retest reliability for each item of the scale ranged from .56 to .70. The data are discussed in view of current controversies in the factor structure of teacher ratings of DSM-III-R ADHD symptoms.This research was supported by FINEP (42.88.0138.00) and FUNPENE.

GLOBAL PROCESSING OF BIOLOGICAL MOTIONS 总被引:1,自引:0,他引:1
Abstract— The structure of the human form is quickly and unequivocably recognized from 10 to 13 points of light moving as if attached to the major joints and head of a person walking Recent psychophysical and computational models of this process suggest that these displays are organized by low-level processing constraints that delimit the pair-wise connections of the point lights In the current research, these low-level constraints were rendered uninformative by a masking paradigm The results from four experiments converged to show that the perception of structure in a point-light walker display does not require the prior detection of individual features or local relations 相似文献

Several studies have shown a negative linear relationship between speech rate and memory span. This relationship has implications for bilingual studies, as span could be larger in a bilingual's secondary language provided that pronunciation rate is faster than in the mother language. The purpose of this study was to investigate the effects of digit word length on digit span in bilinguals. Experiment 1 tested the effects of digit syllable length on speech rate in five different bilingual groups. Results revealed that digit-reading rates were significantly faster in all mother languages. Experiment 2 examined more closely the correspondence between speech rate and digit span with Portuguese-English bilinguals. Results showed that digit-reading rates were faster and digit span larger in the mother language even if the mean number of syllables per digit was higher. The superiority of mother tongue was discussed according to the view that digits are subject to massive practice in one's native language with a strong tendency to be abbreviated, thus reducing its spoken duration. 相似文献

Two experiments tested 3- and 5-month-old infants' sensitivity to properties of point-light displays of human gait. In Experiment 1, infants were tested for discrimination of point-light displays of a walker and a runner, which, although they differed in many ways, were equivalent with regard to the phasing of limb movements. Results revealed that 3-month-old, but not 5-month-old, infants discriminated these displays. In Experiment 2, the symmetrical phase-patterning of the runner display was perturbed by advancing two of its limbs by 25% of the gait cycle. Both 3- and 5-month-old infants discriminated the walker display from this new phase-shifted runner display. These findings suggest that 3-month-old infants respond to the absolute and relative motions within a single limb, whereas 5-month-old infants respond primarily to the relations between limbs and, in particular, to the bilateral symmetry between the limbs. 相似文献

The purpose of this study was to assess several acoustic features of the voices of 26 parkinsonian patients under two conditions, with and without bilateral chronic stimulation of the subthalamic nucleus (STN) to estimate the effectiveness of this procedure on parkinsonian speech. When compared to unstimulated patients, stimulated patients showed longer duration of sustained vowels, shorter duration of sentences, nonsense words, and pauses, more variable fundamental frequency (f0) in sentences, and more stable f0 during sustained vowels. Relative intensity was unchanged in both conditions. Further acoustic analyses are warranted to clarify the role of STN stimulation on parkinsonian speech. 相似文献

Background. Adolescence represents a critical period for brain
development, addressed by neurodevelopmental models to frontal,
subcortical-limbic, and striatal activation, a pattern associated with rise of
impulsivity and deficits in inhibitory control. The present study aimed at
studying the association between self-report measures of impulsivity and
inhibitory control with executive function in adolescents, employing structural
equation modeling. Method. Tests were administered to 434 high
school students. Acting without thinking was measured through the Barratt
Impulsiveness Scale and the Dickman Impulsivity Inventory, reward sensitivity
through the Behavioral Activation System, and sensation seeking through the
Zuckerman–Kuhlman–Aluja Personali- ty Questionnaire. Inhibitory control was
assessed through the Behavioral Inhibition System. The performance at the
Wisconsin Card Sorting Task indicated executive function. Three models were
specified using Sample Covariance Matrix, and the estimated parameters using
Maximum Likelihood. Results. In the final model, impulsivity and
inhibitory control predicted executive function, but sensation seeking did not.
The fit of the model to data was excellent. Conclusions. The
hypothesis that inhibitory control and impulsivity are predictors of executive
function was supported. Our results appear informative of the validity of
self-report measures to examine the relation between impulsivity traits rather
than others to regulatory function of cognition and behavior. 相似文献
