T1 - Mnemonic training for the acquisition of skilled digit memory N2 - This article outlines a research strategy for investigating, in a laboratory setting, the acquisition and the "limits" of a cognitive skill. Expert digit memory is used as an illustration. Two participants with initial average digit- and word-span memory were trained to memorize and reproduce strings of 80 to 90 digits presented at 10- to 1-sec rates. The instruction and training program, based on a theory of skilled memory, focused on three components: (a) acquisition of a mnemonic system (i.e., recoding digits into historical dates or concrete nouns), (b) use of a long-term memory retrieval structure (i.e., instruction in the Method of Loci), and (c) improvement in processing speed. After 86 experimental sessions, one participant recalled 90 random digits presented at a 1-sec rate. The digits were, however, constrained to be compatible with the participant's historical knowledge. The second participant recalled 80 random digits presented at a 5-sec rate after 70 sessions. Speed of encoding and retrieval processing was the only component that required extensive practice for skilled digit-memory acquisition.

T1 - Testing-the-limits, expertise, and memory in adulthood and old age N2 - This research has three interrelated foci: (i) engineering and testing a cognitive model of expert memory, (ii) the study of intellectual reserve capacity and (iii) the use of a testing-the-limits methodology to magnify and delineate age differences in limits of reserve capacity. The assumption is that age differences are magnified if studied at high levels of expertise or task difficulty. Results from age-comparative point training studies in expert memory are reported. Both young and elderly subjects reached high levels of skilled memory, confirming the model. However, despite this sizeable reserve capacity, when compared to IQ-eguivalent young adults, superior elderly showed decline in upper limits of function.

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 - Kliegl, Reinhold T1 - An apology for research integration in the study of psychotherapy N2 - Criticisms of the integration of psychotherapy-outcome research performed by Smith, Glass, and Miller (1980) are reviewed and answered. An attempt is made to account for the conflicting points of view in this disagreement in terms of certain issues that have engaged philosophers of science in the 20th century. It is hoped that, in passing, something useful is learned about research of many types on psychotherapy.

A1 - Dittmann-Kohli, Freya A1 - Kliegl, Reinhold T1 - Reserve capacity of the elderly in aging-sensitive tests of fluid intelligence : replication and extension N2 - Fluid intelligence belongs to that cluster of intellectual abilities evincing aging loss. To examine further the range of intellectual reserve available to aging individuals and the question of replicability in a new cultural and laboratory setting, 204 healthy older adults (mean age = 72 years; range = 60-86) participated in a short-term longitudinal training study. For experimental subjects, 10 sessions consisted of cognitive training involving two subability tests (Figural Relations, Induction) of fluid intelligence. The pattern of outcomes replicates and expands on earlier studies. Older adults have the reserve to evince substantial increases in levels of performance in fluid intelligence tests. Transfer of training, however, is narrow in scope. Training also increases accuracy of performance and the ability to solve more difficult test items. Difficulty level was estimated in a separate study, with a comparable sample of N = 112 elderly adults. Future research is suggested to examine whether intellectual reserve extends to near-maximum levels of performance.

The first module rescales eye positions to coordinates of the display. The second and third modules reduce data to a fixation format and identify areas of bad measurement by means of iterative passes over the data. In the fourth module iterative algorithms are employed for the identification of line numbers and for achieving congruence between fixations and display.
