Domain-Specific Knowledge and Memory Performance: A Comparison of High- and Low-Aptitude Children
(1989)
Two studies compared memory performance and text comprehension of groups that were equivalent on domain-specific knowledge but differed in overall aptitude, to investigate whether prior knowledge about a particular domain or overall aptitude level was more important when the task was to acquire and use new information in the domain of interest. Both studies dealt with third-, fifth-, and seventh-grade soccer experts' and novices' memory and comprehension of a story dealing with a soccer game. Several measures of memory performance, memory monitoring, and text comprehension were used. Levels of soccer knowledge and of overall aptitude were varied in a factorial design. Neither study detected significant differences between high-aptitude and low-aptitude experts, regardless of their ages. Low aptitude experts outperformed high-aptitude novices on all memory and comprehension measures. The results indicate that domain-specific knowledge can compensate for low overall aptitude on domain-related cognitive tasks.
Second- and fourth-grade children were classified according to their knowledge of soccer (experts vs. novices) and IQ (high vs. low), and given 2 sort-recall tasks. One task included items related to the game of soccer and the other included items from familiar natural language categories. Previous research has shown that expertise in a snbject can compensate for low levels of performance on text comprehension tasks. Our results, the flrst examing the effects of both expertise and intelligence on a strategic memory task, were that soccer expert children recalled more items on the soccer list bnt not on the nonsoccer list than soccer novice children. However, soccer expertise did not modify a significant effect of IQ level, with high-IQ children recalling more than low-IQ children for all contrasts. Interest in soccer was found to be related to expertise but did not contribute to differences in memory performance. The results demonstrate that the knowledge base plays an important role in children's memory, but that domain knowledge cannot fully eliminate the effects of IQ on sort-recall tasks using domain-related materials. That is, although rich domain knowledge seemed to compensate for low aptitude, in that low-aptitude experts performed at the level of high-aptitude novices, its effects were not strong enough to eliminate performance differences between highand low-aptitude soccer experts.

The nature of good information processing is outlined as determined by intact neurology, information stored in long-term memory, and general cognitive tendencies, attitudes, and styles. Educators can promote the development of good information processing by promoting what is in long-term memory. This can be accomplished by teaching important literary, scientific, and cultural knowledge; teaching strategies; motivating the acquisition and use of important conceptual knowledge and strategies; and encouraging the general tendencies supporting good information processing. Good information processing can be produced by years of appropriate educational input. Good information processors cannot be produced by short-term interventions.
Vorgestellt wird ein Versuch, die in der einschlägigen literatur postulierte multifaktorielle Bedingtheit von Rechtschreibleistungen in der Grundschule über ein angemessenes methodisches Design zu prüfen. Zentral ist dabei die Frage, ob sich identische Kausalstrukturen für beginnende und geübte Rechtschreiber (Schüler der zweiten w. vierten Klasse) nachweisen lassen. Konventioneffe Verfahren der Kausafanafysa hatten sich in der Primärstudie (Schneider 1980) als unökonomisch und wenig aussagekräftig erwiesen, 10 daß in der Sekundäranalvse auf eine flexiblere Prozedur zurückgegriffen wird. Mit diesem Verfahren zur AnaIVse von Strukturgleichungssysteman (LiSREL) ist es möglich, für die Gruppe der Zweitund Viertkläßler Modelle zu entwickeln und zu überprüfen, die mit den Ausgangsdaten kompatibel sind. Als wesentliches Ergebnis zeigt sich, daß die theoretisch postulierte Bedingungsstruktur nur für die Viertkläßler (eingeschränkt) bestätigt werden kann, während für die Schüler der zweiten Klassenstufe ein grundlegend verschiedenes Muster resultiert.
Im vorliegenden Beitrag wird der Versuch gemacht, neuere Befunde der kognitiven Psychologie, insbesondere der Expertiseforschung, zur Entwicklung außergewöhnlicher Fertigkeiten und Kenntnisse auf den Bereich des Sports zu übertragen und damit deren Generalisierungsmöglichkeiten zu prüfen. In einem ersten Schritt werden dabei die Grundannahmen der traditionellen fähigkeitsorientierten Leistungsprognose mit denen der neueren Expertiseforschung verglichen und im Hinblick auf ihre empirische Bewährung untersucht. Der zweite Schritt besteht darin, daß mögliche Parallelen zwischen der Entwicklung kognitiver und sportlicher Expertise aufgezeigt und an Fallbeispielen demonstriert werden. Dies leitet zum Schwerpunkt des vorliegenden Beitrags über, der in einer Reanalyse von Daten besteht, die im Rahmen einer fünfjährigen Längsschnittstudie an jugendlichen deutschen Tennistalenten gewonnen wurden (vgl. Rieder, Krahl, Sommer, Weicker & Weiss, 1983). Da in dieser Untersuchung sowohl Daten zur Entwicklung allgemeiner motorischer Basisfähigkeiten wie auch zur Entwicklung sportartspezifischer Fertigkeiten erhoben worden waren, ließ sich die Bedeutsamkeit dieser beiden Komponenten für den sportlichen Erfolg relativ genau bestimmen. Weiterhin waren Informationen zu Hintergrundmerkmalen wie z.B. der elterlichen Unterstützung, der Trainingsintensität sowie Merkmalen der Motivation und Konzentration verfügbar, von denen anzunehmen war, daß sie zusätzlich dazu geeignet sein sollten, individuelle Unterschiede in den beobachteten Entwicklungsverläufen zu erklären.
The goal of the present study was to determine whether 4- and 5-year-old kindergarten children could be trained to maintain an organizational strategy over 2- and 8 week periods through an elaborate training program. A second goal was to assess the effects of the training program on strategy awareness. Twenty-eight kindergarten children were pretested on two sort-recall tasks and their awareness of the use of the clustering strategy was assessed through a protocol type procedure. Half the children received seven half-hour sessions of individual training in the clustering strategy and half the children participated in a control group. Both groups were post-tested on two sort-recall tasks 2 weeks following training and again 8 weeks following training. Strategy awareness, as measured by verbal protocol, was assessed at both post-test points. The elaborate strategy training program was successful in inducing short- and long-term strategy maintenance of the clustering strategy. Trained children’s clustering during sorting and clustering during recall was consistently related to the amount of items correctly recalled. No differences in strategy awareness were found. These findings demonstrate that the elaborate training procedure used in this study can be a very effective memory technique for young kindergarten children.
