25 undergraduates studied the stimulus pictures of common objects successively presented as spaced or massed repetitions, or one at a time. Immediately after a study period, they were given a free-recall test followed by a perceptual identification test. Analysis indicated that spacing effects were observed on the free-recall test but not in perceptual identification. On the later test, each stimulus picture was exposed for a short period and subjects were more likely to use perceptual cues than on first the test. Thus, the spacing effects on memory may be eliminated at test as there is no benefit of conceptual cues.

The present study investigated encoding variability in self-generated elaboration on incidental memory as a function of the type of presentation which was either massed or spaced. The subjects generated different answers to a “why” question for the first and the second presentations of a target sentence in a self-generated elaboration condition. In an experimenter-provided elaboration condition they then rated the appropriateness of the different answers provided by the experimenter for the first and second presentations. This procedure was followed by two free recall tests, one of which was immediate and the other delayed. A self-generated elaboration effect was observed in both the spaced and the massed presentations. These results indicated that the self-generated elaboration effect was facilitated, even in the massed presentation because the different answers to the first and the second presentations led to a richer encoding of each target.

Zusammenfassung. Es werden Ergebnisse der Würzburger Längsschnittstudie dargestellt, in der der Entwicklungsverlauf des strategischen Gedächtnisses vom letzten Kindergartenjahr bis zum Ende der vierten Klasse in halbjährigem Abstand untersucht wurde. Für eine Stichprobe von ca. 100 Kindern konnte das in der Münchner LOGIK-Studie gefundene Muster des sprunghaften Strategieerwerbs für die Sortierstrategie bestätigt werden, während sich bei der Wiederholungsstrategie kein bedeutsamer Unterschied in der Art des Strategieerwerbs zeigte. Der kombinierte Gebrauch von Sortier- und Wiederholungsstrategie brachte Vorteile bei der Abrufleistung der Sort-Recall-Aufgabe, nicht aber der Serial Learning-Free-Recall-Aufgabe. Für zukünftige Forschungsarbeiten wird der Einsatz einer Aufgabe zur Untersuchung der Strategieentwicklung empfohlen.

Abstract. The spacing effect refers to the finding that memory for repeated items improves when the interrepetition interval increases. To explain the spacing effect in free-recall tasks, a two-factor model has been put forward that combines mechanisms of contextual variability and study-phase retrieval (e.g., Raaijmakers, 2003 ; Verkoeijen, Rikers, & Schmidt, 2004 ). An important, yet untested, implication of this model is that free recall of repetitions should follow an inverted u-shaped relationship with interrepetition spacing. To demonstrate the suggested relationship an experiment was conducted. Participants studied a word list, consisting of items repeated at different interrepetition intervals, either under incidental or under intentional learning instructions. Subsequently, participants received a free-recall test. The results revealed an inverted u-shaped relationship between free recall and interrepetition spacing in both the incidental-learning condition and the intentional-learning condition. Moreover, for intentionally learned repetitions, the maximum free-recall performance was located at a longer interrepetition interval than for incidentally learned repetitions. These findings are interpreted in terms of the two-factor model of spacing effects in free-recall tasks.

This study examined whether additional articulatory rehearsal induced temporary durability of phonological representations, using a 10-s delayed nonword free recall task. Three experiments demonstrated that cumulative rehearsal between the offset of the last study item and the start of the filled delay (Experiments 1 and 3) and a fixed rehearsal of the immediate item during the subsequent interstimulus interval (Experiments 2 and 3) improved free recall performance. These results suggest that an additional rehearsal helps to stabilize phonological representations for a short period. Furthermore, the analyses of serial position curves suggested that the frequency of the articulation affected the durability of the phonological representation. The significance of these findings as clues of the mechanism maintaining verbal information (i.e., verbal working memory) is discussed.
