However, there is a lack of studies investigating the preconditions and effects of interindividual variability within age groups across different memory tasks. Similarly, our knowledge about the stability of interindividual differences across the life span as well as the sources and the amount of intraindividual variability across memory tasks is scarce. In the present chapter, we concentrate on these neglected issues. First, theoretical assumptions concerning the interindividual and intraindividual variability of memory development are discussed. Next, empirical evidence is presented that seems suited to document the importance of these neglected issues. While we try to give a representative account of the literature, the emphasis is on more recent studies of memory development in children and elderly adults conducted in our laboratory. The results demonstrate that age-related changes and individual differences in the knowledge base are particularly important for describing and explaining individual differences in memory develoment. In comparison, the rote of stable individual differences in basic memory capacities in explaining variations in memory development is less clear given tbe conflicting empirical evidence. In the final section of the chapter consequences for future research are discussed.}, subject = {Ged{\"a}chtnisbildung}, language = {en} } @incollection{Schneider1977, author = {Schneider, Wolfgang}, title = {Taxonomie der Ged{\"a}chtnisleistungen schwacher und normaler Rechtschreiber}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-69476}, publisher = {Universit{\"a}t W{\"u}rzburg}, year = {1977}, abstract = {No abstract available.}, subject = {Ged{\"a}chtnisleistung}, language = {de} } @incollection{ZimmermannStopper1987, author = {Zimmermann, U. and Stopper, Helga}, title = {Electrofusion and electropermeabilization of cells}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-73065}, publisher = {Universit{\"a}t W{\"u}rzburg}, year = {1987}, abstract = {No abstract available.}, subject = {Elektrofusion}, language = {en} } @incollection{LohseKlotzSchwabe1987, author = {Lohse, Martin J. and Klotz, Karl-Norbert and Schwabe, Ulrich}, title = {Functional characterization of A1 adenoosine receptors by photoaffinity labelling}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-86097}, publisher = {Universit{\"a}t W{\"u}rzburg}, year = {1987}, abstract = {The ligand-binding subunit ofthe A1 adenosine receptor has been identified in membranes with the photoaffinity Iabel R-2-azido-N6-p-hydroxyphenylisopropyladenosine (R-AHPIA). Covalent labelling ofthe A1 receptor can also be achieved in intact cells. The dissociation of the radioiodinated label (1251-AHPIA) from isolated rat fat cells was incomplete after UV irradiation, leaving about 20°/o of irreversible specific binding. Such covalent labelling of the receptor led to a concentration-dependent reduction of cellular cyclic AMP levels. This persistent effect of covalent labeHing occurred with an IC50 value of 9 nM, as compared to an IC50 value of 0.9 nM for the direct reduction of cyclic AMP Ievels by the ligand. The difference in the IC5o values can be explained by assuming spare receptors. This hypothesis was verified in binding studies using [ 3HJPIA as a radioligand. R-AHPIA inhibited binding of [3H)PIA to intact fat cells with a K1 value of about 20 nM, which is about 20 tim es high er than the corresponding IC50 value of cyclic AMP reduction. These data show that the A1 receptor is activated according to the occupancy theory. The high sensitivity of the activation in intact ceJis is due to a large number of spare receptors.}, subject = {Adenosinrezeptor}, language = {en} } @incollection{AltschmiedSchartl1994, author = {Altschmied, Joachim and Schartl, Manfred}, title = {Genetics and molecular biology of tumour formation in Xiphophorus}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-69752}, publisher = {Universit{\"a}t W{\"u}rzburg}, year = {1994}, abstract = {No abstract available.}, subject = {Schwertk{\"a}rpfling}, language = {en} }
