This study examines the role of the lexicon and grammatical structure building in early grammar. Parent-report data in CDI format from a sample of 1151 German-speaking children between 1;6 and 2;6 and longitudinal spontaneous speech data from 22 children between 1;8 and 2;5 were used. Regression analysis of the parent-report data indicates that grammatical words have a stronger influence on concurrent syntactic complexity than lexical words. Time-lagged correlations using the spontaneous speech data showed that lexical words at 1;8 predict subsequent MLU at 2;1 significantly; grammatical words do not. MLU at 2;5 is significantly predicted by grammatical words and no longer by lexical words. The influence of different grammatical subcategories on subsequent MLU varies. Use of articles and the copula at 2;1 most strongly predicts MLU at 2;5. Children use both types of articles and multiple determiners before a noun to the same extent as adults. The present results are suggestive of early grammatical structure building.
In assessing adolescent behavior difficulties, parents, teachers, and the adolescents themselves are key informants. However, substantial disagreement has been found between informants. Specifically, children with attention-deficit/hyperactivity disorder (ADHD) tend to overestimate their competencies, also known as "positive (illusionary) bias." This study compared parent, teacher, and adolescent ratings of ADHD and other behavioral symptoms in a sample of 114 adolescents with ADHD. Further, the effect of cross-informant disagreement (CID) on treatment outcomes was investigated in a subsample of 54 adolescents who had undergone a training and coaching intervention. Overall, there was moderate agreement among informants. Parent and adolescent ratings were more strongly correlated with each other than with teacher ratings. The strongest discrepancy was found between teacher and adolescent ratings on prosocial behavior. This discrepancy explained 12% of the variance in parent-rated ADHD symptom severity after the intervention. The treatment was less effective in participants with high teacher-adolescent disagreement on prosocial behavior (d = 0.41) than with low disagreement (d = 0.98). These findings suggest that professionals working with adolescents with ADHD should consider multiple sources of information before initiating treatment and pay attention to cross-informant disagreements because these may indicate a risk of diminished treatment effects.
ADHS und Schule
(2016)
Aufmerksamkeits- und Hyperaktivitätsstörungen (ADHS) zählen zu den häufigsten Verhaltensstörungen des Kindes- und Jugendalters (ca. 5-7 %). Neben Lern- und Leistungsschwierigkeiten kann dadurch vor allem die Interaktion mit Gleichaltrigen und Erwachsenen problematisch sein. Lehrkräfte und Eltern sind somit beim Vorliegen einer ADHS besonders herausgefordert. Das Buch liefert auf der Grundlage klinisch-entwicklungspsychologischer und (sonder-)pädagogischer Theorien sowie empirischer Befunde grundlegendes Wissen zur Symptomatik, Entstehung und Diagnostik von ADHS. Darauf aufbauend werden praktische Handlungsempfehlungen und evaluierte Maßnahmen im Umgang mit Kindern und Jugendlichen mit ADHS sowie Beratungsaufgaben im Kontext Schule vorgestellt. Das Ganze wird angereichert durch Fallbeispiele und Materialien (Checklisten, Beobachtungsbögen usw.).
