T1 - Ausbildung zum Gedächtniskünstler : ein experimenteller Zugang zur Überprüfung von Theorien kognitiven Lernens und Alterns N2 - Der hier berichtete Forschungsansatz kombiniert entwicklungs- und kognitionspsychologische Fragestellungen. Das entwicklungspsychologische Ziel war, Potential und Grenzen latenter kognitiver Leistungsreserven bei jungen und älteren Erwachsenen sichtbar zu machen. Eine systematische Heranführung an Leistungsgrenzen sollte außerdem die unterschiedliche Alterssensitivität kognitiver Prozesse verdeutlichen und zu einer Vergrößerung interindividueller Unterschiede führen. Das kognitionspsychologische Ziel war, die Genese kognitiver Expertise unter Laborbedingungen zu simulieren, wobei vor allem die Transformation von Laien- in Expertenwissen untersucht werden sollte. Diese Überlegungen wurden in einem Trainingsprogramm überprüft, in dessen Verlauf junge und ältere Erwachsene in einer Gedächtniskunst für das Behalten von Zufallszahlen und Wortlisten unterwiesen wurden. Die Brauchbarkeit dieses experimentellen Paradigmas für die Überprüfung der theoretischen Fragen wird durch Ergebnisse aus vier Einzelfallstudien belegt. N2 - This research examines developmental and cognitive psychological questions. The developmental interest is to demonstrate the potential and limits of latent cognitive reserve in young and older adults. A testing-the-limits methodology is advocated to identify differential sensitivity to aging in cognitive processes and to magnify interindividual differences. The cognitive psychological goal is to simulate the acquisition of cognitive expertise in a laboratory situation and, in particular, to study processes that transform novice to expert knowledge. In the context of a training program that was designed to test these assumptions, young and older adults acquired a memory expertise that allowed recall of random digit strings and lists of words. Results from four case studies are used to illustrate and to document the utility of this research paradigm.

A1 - Sowarka, Doris A1 - Kliegl, Reinhold T1 - Cognitive training research on fluid intelligence in old age : what can older adults achieve by themselves? N2 - Cognitive research on the plasticity of fluid intelligence has demonstrated that older adults benefit markedly from guided practice in cognitive skills and problem-solving strategies. We examined to what degree older adults are capable by themselves of achieving similar practice gains, focusing on the fluid ability of figural relations. A sample of 72 healthy older adults was assigned randomly to three conditions: control, tutor-guided training, self-guided training. Training time and training materials were held constant for the two training conditions. Posttraining performances were analyzed using a transfer of training paradigm in terms of three indicators: correct responses, accuracy, and level of item difficulty. The training programs were effective and produced a significant but narrow band of within-ability transfer. However, there was no difference between the two training groups. Older adults were shown to be capable of producing gains by themselves that were comparable to those obtained following tutor-guided training in the nature of test-relevant cognitive skills.

T1 - Das Janusgesicht des Alters : über Wachstum und Abbau in Intelligenz und Gedächtnis N2 - Vier Forschungsansätze im Bereich der Altersintelligenz und des Altersgedächtnisses werden referiert: Untersuchungen (1) Uber unterschiedliche Altersverläufe intellektueller und kognitiver Prozesse, (2) über interindividuelle Variabilität und historischen Wandel, (3) über Plastizität und Reservekapazität und (4) über Leistungsgrenzen. Das Wesen der Altersintelligenz erschöpft sich nicht in einem Prozeß des Leistungsabfalls. Vielmehr treten sowohl Wachstum als auch Abbau und komplexe Wechselwirkungen zwischen beidem auf. Altersbedingter Abbau zeigt sich am ehesten an den Leistungsgrenzen der Grundmechanismen der Intelligenz. Wachstum kann in jenen Bereichen stattfinden, in denen Menschen Wissenssysteme weiterentwickeln und üben (Pragmatik der Intelligenz). Die Methode des Belastungstests (Testing-the-Limits oder Grenztesten) wird als eine Strategie vorgestellt, mit deren Hilfe Mechanismen positiver und negativer Veränderungen beim kognitiven Altern bestimmt werden können. Die Anwendung des kognitiven Belastungstests wird für die neuropsychologische Forschung, beispielsweise für Untersuchungen über die Altersdemenz, empfohlen.

T1 - Effects of cognitive training and testing on intellectual efficacy beliefs in elderly adults N2 - Elderly adults (N = 116; average age = 73 years) were randomly assigned to one of four treatment groups varying in the amount of training and testing on fluid intelligence tests. They were compared before and after treatment on self-efficacy and utility beliefs for intelligence tests and everyday competence. Although both ability training and extended retest practice resulted in significant gains in objective test performance (Baltes, Kliegl, & Dittmann-Kohli, 1988), only ability training resulted in positive changes in self-efficacy. However, these changes were restricted to testrelated self-efficacy. Training had no impact on perceived utility or on everyday self-efficacy beliefs. Implications of the results are discussed with regard to interventions to increase intellectual self-efficacy in elderly persons.

A1 - Kliegl, Reinhold T1 - Further testing of limits of cognitive plasticity : negative age differences in a mnemonic skill are robust N2 - Earlier testing-the-limits research on age differences in cognitive plasticity of a memory skill was extended by 18 additional assessment and training sessions to explore whether older adults were able to catch up with additional practice and improved training conditions. The focus was on the method of loci, which requires mental imagination to encode and retrieve lists of words from memory in serial order. Of the original 37 subjects, 35 (16 young, ranging from 20 to 30 years of age, and 19 older adults, ranging from 66 to 80 years of age) participated in the follow-up study. Older adults showed sizable performance deficits when compared with young adults and tested for limits of reserve capacity. The negative age difference was substantial, resistant to extensive practice, and applied to all subjects studied. The primary origin for this negative age difference may be a loss in the production and use of mental imagination for operations of the mind.
