The Strengths and Difficulties Questionnaire (SDQ) is a widespread tool for assessing behavior problems in children and adolescents. Despite being investigated thoroughly concerning both validity and reliability, peer reviewed studies that provide norms, especially for preschool children, are lacking. This paper provides Swedish norms using data from a large community sample of children aged 3–5, based on mothers’, fathers’, and preschool teacher’s ratings. Preschool teachers’ ratings were generally lower than parents’ ratings, which contradicts some previous studies. Differences between girls and boys were found, suggesting that boys display higher levels of behavior problems. Lower parental education and country of origin outside of Sweden were also associated with more difficulties. Cut-offs are presented for each age group, gender and rater category. Population-specific norms and percentile cut-offs provided in this study facilitate identifying children in need of interventions in paediatric care and enable cross-country comparisons of children’s mental health problems. 相似文献

Phonology, Working Memory, and Foreign-language Learning 总被引:15,自引:0,他引:15

Three tasks were used to predict English learning by Finnish children over a three-year period. In the pseudoword repetition task the pupils had to repeat aloud tape-recorded pseudowords sounding like Finnish or English. In the pseudoword copying task the pupils saw strings of letters resembling Finnish or English words and copied them when they had disappeared from view. When comparing syntactic-semantic structures, the pupils had to find the syntactically matching pairs from two sets of Finnish sentences. Repetition and copying accuracy and the ability to compare syntactic-semantic structures predicted English learning. Intercorrelations between test scores and English and mathematics grades suggest that repetition and copying accuracy were specifically related to language learning. It is concluded that the ability to represent unfamiliar phonological material in working memory underlies the acquisition of new vocabulary items in foreign-language learning. 相似文献

The Effect of Word Length on Immediate Serial Recall Depends on Phonological Complexity, Not Articulatory Duration 总被引:4,自引:0,他引:4
Elisabet Service 《The Quarterly Journal of Experimental Psychology Section A: Human Experimental Psychology》1998,51(2):283-304
Immediate recall for sequences of short words is better than for sequences of long words. This word-length effect has been thought to depend on the spoken duration of the words (Baddeley, Thomson, & Buchanan, 1975) or their phonological complexity (Caplan, Rochon, & Waters, 1992). In Finnish both vowel and consonant quantity distinguish between words. Long phonemes behave like phoneme repetitions. In Experiment 1, subjects were presented with auditory lists of three kinds of pseudowords based on Finnish phonotactics: short CVCV-structures (e.g. / tepa/ ), long two-syllable items with long phonemes (e.g. / te: p: a / ), and long three-syllable items with CVCVCV structures (e.g. / tepalo / ). Although both kinds of long stimuli (of identical spoken length) took longer to read, only three-syllable items were more difficult to remember than the short stimuli. Experiment 2 contrasted the effect of number of syllables with number of different phonemes. The long two-syllable items were replaced by two-syllable items of equal spoken duration but containing six different phonemes (e.g. / tiempa / ). These two-syllable items were as difficult to recall as were the three-syllable items. Experiment 3 controlled for the possibility that long stimuli might be rehearsed in a shorter form. It is concluded that aspects of phonological complexity are critical for word-length effects. Implications of this finding for working memory theory are discussed, and future work based on multi-layered phonological representations is proposed. 相似文献

BORG, G., BRATFISCH, O. & DORNI'C, S. On the problems of perceived difficulty. Scand. J. Psychol. , 1971, 12, 249–260.–The development and meaning of the concept of "perceived difficulty" is presented. A concise survey of experiments carried out so far is given with regard to the main theoretical, methodological and applied problems at which the investigations aimed. A substantial part of the paper is devoted to the analysis of the concept of perceived difficulty and to the possibilities of measurement. The concept of perceived difficulty is dealt with also in a differential connection and a model for interindividual comparisons is suggested. It is emphasized that a systematic investigation of perceived difficulty is both possible and useful, and that it yields an opportunity to improve and facilitate the construction of psychological tests. Finally, possible future research projects are briefly outlined. 相似文献

This study assessed the effectiveness of the Utah State University Self-Concept Protocol Modules in changing teacher behaviors presumed to be related to pupil self-concept. This research focused on teachers and handicapped pupils in mainstreamed intermediate grade classrooms. The modules cover specific teacher behaviors including ways of expressing anger, listening skills and nonjudgemental messages, praising and giving instructions, and ways of fostering positive self-perception statements by pupils. The experimental group contained 15 teachers; 18 teachers were in the control group. Seven hundred and fifteen pupils (251 of which were in the experimental group) from the classrooms of the participating teachers were included. Observational data were collected on the teacher behaviors. The intermediate form of the Piers-Harris Children's Self-Concept Scale was administered before and after teachers were trained. Analyses of covariance (with prescores as the covariates) in which the experimental treatment was the independent variable and the postscores for the teacher behaviors were the dependent variables revealed a significant difference between the experimental and control group teachers. The experimental group had more favorable postscores than the control group on four of the teacher behaviors. For children's self-concept postscores, a significant treatment X pupil classification interaction was found indicating that experimental group handicapped pupils scored significantly higher (p<.05) than the control group handicapped pupils. Enhancement was not obtained for either the nonhandicapped nonminority or minority group pupils. 相似文献

A model and algorithm for multidimensional scaling with external constraints on the distances 总被引:1,自引:0,他引:1
A method for externally constraining certain distances in multidimensional scaling configurations is introduced and illustrated. The approach defines an objective function which is a linear composite of the loss function of the point configurationX relative to the proximity dataP and the loss ofX relative to a pseudo-data matrixR. The matrixR is set up such that the side constraints to be imposed onX's distances are expressed by the relations amongR's numerical elements. One then uses a double-phase procedure with relative penalties on the loss components to generate a constrained solutionX. Various possibilities for constructing actual MDS algorithms are conceivable: the major classes are defined by the specification of metric or nonmetric loss for data and/or constraints, and by the various possibilities for partitioning the matricesP andR. Further generalizations are introduced by substitutingR by a set ofR matrices,R
i
,i=1, ...r, which opens the way for formulating overlapping constraints as, e.g., in patterns that are both row- and column-conditional at the same time. 相似文献

The performance of 12 subjects in a hand steadiness task was compared at different work loads. Hand steadiness expressed in the form of values of hand shakiness was found not to increase linearly with work intensity. On the contrary, the relation between hand shakiness and activation level, induced by physical work, was found to be positively accelerated by an exponent of 1.6. Subjective effort measured by a ratio estimation method grew, likewise, according to a positively accelerating function with an exponent of about 1.6, while subjective effort according to the "RPE" category scale like hear rate grew linearly with work load. 相似文献

Scales on the badness of 10 offenses/crimes are derived by using the five most common scaling methods: averaging of the badness-ratings of the stimuli on an 11-point scale; mean ranks of complete rankings of the 10 stimuli; Thurstone scales for complete forced-choice and constant-sum pair comparisons, resp.; and ratio scales derived from pairwise ratio judgments for all pairs. From older investigations, a logarithmic correspondence of ratio scales and Thurstone or average ratings, resp., can be predicted. The data corroborate this prediction. They show furthermore that the ratio scale has an exceedingly close, logarithmic relation to each of the other four scales. We therefore conclude that, once a universe has been shown to be scalable, a scale can be constructed very economicaly by simply averaging ratings. 相似文献
