TY - JOUR A1 - Schneider, Wolfgang A1 - Bjorklund, David F. T1 - Expertise, aptitude, and strategic remembering N2 - 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.

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.

N2 - Previous research has shown German children to be more strategic on sort-recall memory tasks than their American age-mates, and to show fewer effort-related attributions. We conducted this study to determine if those differences are due to systematic differences in the strategy instruction and attributional beliefs of German and U.S. teachers, and to explore metacognitive instructional practices in the two countries. Teachers responded to a questionnaire that inquired about their use of strategy instructions, fostering of reflective thinking in pupils, sources of children’s learning problems, and modeling of metacognitive skills such as monitoring. The second part of the questionnaire asked about the reasons underlying children’s academic successes and failures. German teachers reported more instruction of task-specific strategies, while American teachers showed more effort-related attributions. The types of strategies instructed and types of learning problems most frequently described varied across the two countries, and also according to how many years the teachers had taught. Results were discussed regarding their implications for metacognitive developmental theory, particularly regarding culture and other environmental influences on the development of controlled processing.

Ghildren could fool a competitor by hiding targets in locations that were labeled with semantically weakly associated cues and help a cooperative partner by hiding them in semantically highly associated locations. Very few 4-year-olds, half the 5-year-olds, and almost all 6-year-olds appropriately chose semantically highly vs. weakly associated hiding places to make the targets easy vs. difficult to find. The second experiment showed that 4-year-olds did not strategically manipulate cues as sources of information, although they themselves proficiently used them as such in a search task. These findings are discussed with regard to research on children's developing understanding of origins of knowledge and belief and with regard to recent claims that young preschoolers possess a metacognitive understanding of cognitive cuing.

A1 - Schneider, Wolfgang A1 - Pressley, Michael T1 - The challenges of teaching good information processing to learning disabled students N2 - A MODEL of good information processing is sketched, describing how metacognitive knowledge influences strategy selection and use. Three factors pose particular problems for learning disabled students as they attempt to acquire metacognitive knowledge and to use study strategies productively: neurological impairments; deficiencies in general world knowledge; and negative beliefs, attitudes, and styles that limit self-efficacy. Creating an educational atmosphere that explicitly builds conceptual (domain-specific) knowledge and teaches positive beliefs about learning potential is essential in promoting metacognitively-oriented instruction.

Both level of soccer knowledge and overall aptitude were varied in a factorial design. Third, fifth, and seventh grade children were given several measures of text recall and comprehension and were retested on these measures about 1 year later. Performance was more a function of soccer knowledge than of aptitude level.

T1 - Strategy acquisition and transfer among American and German children: Environmental influences on metacognitive development N2 - This study explored the differential effects of strategy training on German and American elementaryschool children and assessed the role of parents in the development of their children's strategic behavior and metacognition. 184 German and 161 American children were pretested on memory and metamemory tasks. Children were then assigned to either an organizational strategy training condition or a control condition. All children were tested on the maintenance and far-transfer of the strategy and task-related metamemory 1 week following training. Parents completed questionnaires about strategy instruction in the home. Strategy maintenance and metacognition were reassessed 6 months following training. German children were more strategic than American children. Instructed children performed better than control children. German parents reported more instruction of strategies in the home. These data suggest that formal education is responsible for aspects of cognitive development that have sometimes been viewed as a function of age.

Second and fourth grade children were presented with clusterable sort/recall lists representing the factorial combinations of high and low interitem association, and high and low category relatedness. Strategy use in the task was rated by the experimenter and also assessed via self reports. General and task-related strategy knowledge tmetamemoryt was also examined. Second graders displayed more category clustering during recall for highly associated items than for weakly associated items. whereas older children’s recall organization (but not recall) was unaffected by this organizational dimension. Correlations among measures of metamemory and organizational behavior indicated that second graders in general were unaware of the importance of categorization strategies for facilitation of recall. On the other hand. sorting during study and task-related metamemory were the most important predictors of fourth graders’ recall performance, thus indicating that most fourth graders used categorization strategies deliberately.

The younger children recalled significantly more items under sort-and-remember than under play-and-remember instructions, whereas no significant recall differences between instructional conditions were found for the older children. However, 6-year-olds showed higher levels of recall than 4-year-olds in both instructional conditions. Category cues were much more effective than color cues, regardless of age. In addition, clustering scores indicated that conceptual organization at both encoding and retrieval increased with age and with instruction. These results show that from 4 to 6 years of age children are learning to spontaneously employ memory strategies. In addition, they highlight the increasing importance of conceptual organization to retention of young children. Finally, the metamemory data suggest that there may be a lag between children’s articulated declarative knowledge about the usefulness of conceptual organization and their procedural use of it.

The effects of coverage, similarity measures, and cluster overlap were studied by including different levels of coverage for the hierarchical algorithms, Euclidean distances and Pearson correlation coefficients, and truncated multivariate normal mixtures in the analysis. The results confirmed the findings of previous Monte Carlo studies on clustering procedures in that accuracy was inversely related to coverage, and that algorithms using correlation as the similarity measure were significantly more accurate than those using Euclidean distances. No evidence was found for the assumption that the positive effects of the use of correlation coefficients are confined to unconstrained mixture models.

Eight classrooms were preselected on the basis of their widely differing slopes obtained in a regression analysis of pre- and posttest achievement scores. Mathematics achievement differences among sixth graders were analyzed in a four-wave design and explained by aptitude and instructional variables in a structural equation framework provided by LISREL. The results demonstrate the local nature of achievement models in that neither their measurement nor structural components proved generalizable across both groups of classrooms. Mention is also made, however, of technical problems and analytical ambiguities in the interpretation of these results.

With regard to validity, results from a longitudinal study of 36 depressed patients and nine controls as weil as often schizophrenic patients and their relatives will be referred to. These results are used to illustrate the following principles which have to be taken into account when studying facial behavior: a) communication strongly facilitates facial expression, b) activation of facial behavior follows the "principle of least effort", and c) the principle of individual specificity applies to the association of nonverbal behavior and mood states. Making allowance for these principles has, among others, consequences a) for situations or conditions under which to asses behavior (specifically conditions of communication), b) for data analysis (e.g., dealing with frequent and rare events), and c) for empirical or experimental strategies (e.g., aggregation of single-case longitudinal comparisons). From the results on facial behavior during depression it can be concluded that the nonverbal reaction tendencies of endogenous and neurotic depressed patients differ. Moreover, the differential behavioral pattems observed cast doubt on the assumption of a homogeneity of affects in depression. Taking into account the conditions which govern it, facial behavior has proved to be a valid and, especially, a differential indicator for pathoIogic affective states and their changes. Given the fact that a psychiatric illness generally incorporates emotional problems it is more than surprising that little attention has been paid to the systematic study of emotional behavior. Some of the reasons for this will be clarified in the following. N2 - Dieser Beitrag gibt eine Übersicht über die Möglichkeiten zur Erfassung mimischen Verhaltens. Zur Bewertung der Validität werden Ergebnisse aus einer Verlaufsuntersuchung an 36 depressiven Patienten und neun Kontrollpersonen sowie von zehn schizophrenen Patienten und ihren Angehörigen herangezogen. Diese Ergebnisse sollen die folgenden Prinzipien, die bei der Untersuchung mimischen Verhaltens zu berücksichtigen sind, illustrieren: a) Kommunikation erleichtert in hohem Maße das Auftreten mimischen Ausdrucks, b) die Aktivierung mimischen Verhaltens folgt dem "Prinzip des geringsten Aufwandes", und c) auf die Beziehung zwischen nonverbalem Verhalten und Stimmungszuständen trifft das Prinzip der Individuenzpezifität zu. Aus diesen Prinzipien ergeben sich Konsequenzen a)für die Situationen oder Bedingungen, unter denen Verhalten zu erfassen ist (speziell Bedingungen der Kommunikation), b) für die Datenanalyse (z. B. die statistische Behandlung häufiger und seltener Ereignisse) und c) für empirische oder experimentelle Strategien (z. B. die Aggregation von Einzelfall-Verlaufsbeobachtungen). Aus den Ergebnissen zum mimischen Verhalten in der Depression kann geschlossen werden, daß sich endogen und neurotisch depressive Patienten hinsichtlich ihrer nonverbalen Reaktionstendenzen unterscheiden. Darüber hinaus stellen die differentiellen Verhaltensmuster die Annahme einer Affekthomogenität in der Depression in Frage. Berücksichtigt man die Bedingungen, die das mimische Verhalten steuern, so erweist es sich als valider und insbesondere differentieller Indikator für pathologische affektive Zustände und deren Veränderungen. Angesichts der Tatsache, daß eine psychiatrische Erkrankung im allgemeinen emotionale Probleme beinhaltet, so ist es mehr als erstaunlich, daß bisher dem Studium des unmittelbaren emotionalen Ausdrucksverhaltens so wenig Aufmerksamkeit geschenkt wurde. Einigen Gründen hierfür wollen wir im folgenden nachgehen.

Die Methode besteht aus einer Kombination der Auswahl zutreffender Selbstbeschreibungen ("Probleme") und der Beantwortung motivationsbezogener Zusatzfragen. Jeder Pb wird so zu seinen spezifischen Problemen hinsichtlich der Ausprägung therapierelevanter motivationaler Variablen befragt. Aus der Beantwortung der Zusatzfragen können verschiedene Therapiemotivations- Syndrome (TMS) gebildet werden. Die statistische Absicherung des individuellen Vorkommens eines TMS in den Zusatzbefragungen erfolgt über die Multinominalverteilung. Dabei wird von der Häufigkeit ausgewählter Probleme eines Pb abstrahiert. Die Erprobung des Verfahrens wurde an 211 Inhaftierten einer Jugendstrafanstalt als potentieller Klienten-Population vorgenommen. Als Kontrollgruppe dienten 207 Berufsschüler vergleichbaren Alters. Während bei den Berufsschülern die Häufigkeit bei der Klassifikation in verschiedene TMS-Gruppen immer im zufälligen Bereich lagen, konnten bei den Delinquenten überzufällig häufig besetzte Gruppenstärken gefunden werden. In der Diskussion wurde auf den Unterschied des hier benutzten Klassifikationsverfahrens zur Konfigurations-Frequenzanalyse und zu Maßen Externaler-Internaler-Kontrolle eingegangen. Außerdem wurden Implikationen der Diagnose von Klienten-Therapiemotivation ftir die Entwicklung therapeutischer Verfahren aufgezeigt. N2 - By a configural classification method, clients can be grouped into therapy-motivation syndromes (TMS). The method of examination ist composed of two steps: choice of true self-descriptions from "problem-items" and questions regarding five distinctive motivational variables to the selected items. From the configuration of answers to the motivational questions, the prevailure of a certain TMS can be tested against the expectation of a multinomial distribution. In an empirical test of the method it is shown that juvenile delinquents as potential clients of psychotherapy could be classified into certain TMS-groups. The difference of the described method of the configurational classification to chi-square-analysis and to measures of internalexternal control ist discussed.

This hypothesis was confirmed with a data set originating from dichotomized distributions of a three-variate measure of generalized locus of control.

The amount of damage varied in the stories as weIl as whether the harmdoer apologized or whether someone else compensated the harm. The effect of apology and amount of damage were unrelated to age. Apology reduced the punishment twice as much as amount of damage. The effect of third-party compensation was the same as that of apology, but was reduced in adults to around the amount of damage. Even after compensation of the damage, the prior amount of damage was still - though to a lesser degree - relevant for the punishment judgments. However, the total explanation of the effects of the harmdoer's restitution by apology and third-party compensation was not possible.
