Spacing Repetitions Over Long Timescales: A Review and a Reconsolidation Explanation
نویسندگان
چکیده
Recent accounts of the spacing effect have proposed molecular explanations that explain spacing over short, but not long timescales. In the first half of this paper, we review research on the spacing effect that has employed spaces of 24 h or more across skill-related tasks, language-related tasks and generalization for adults and children. Throughout this review, we distinguish between learning and retention by defining learning (or acquisition) as performance at the end of training and retention as performance after a delay period. Using this distinction, we find age- and task-related differences in the manifestation of the spacing effect over long timescales. In the second half of this paper, we discuss a reconsolidation account of the spacing effect. In particular, we review the evidence that suggests the spacing of repetitions influences the subsequent consolidation and reconsolidation processes; we explain how a reconsolidation account may explain the findings for learning; the inverted-U curve for retention; and compare the reconsolidation account with previous consolidation accounts of the spacing effect.

Effects of Mineralocorticoid Receptors Blockade on FearMemory Reconsolidation in Rats
Reconsolidation memory is defined as a process in which the retrieval of a previously consolidated memory returns to a labile state which is then subject to stabilization. Previous studies have shown that mineralocorticoid receptors (MRs) modulate distinct phases of learning and memory, which display a high concentration and distinct distribution in the hippocampus. Moreover, we found no studie...
متن کاملIranian EFL Learners’ Motivational Fluctuation in Task Performance over Different Timescales
Motivation for learning a new language is both self and time-oriented. The language learner’s motivation experiences gradual fluctuation over time and the view of oneself is different on each timescale of the study. Interaction among different timescales throughout the Second Language Development (SLD) is a novel area of investigation (de Bot, 2015). In order to probe this interactive nature, t...
متن کاملSpacing repetitions over 1 week.
Does varying the spacing of repetitions over intervals as long as I week affect recall? The answer from three experiments is yes. Subjects incidentally processed words repeated within a single list and words repeated in separate lists at list spacings of up to I week. Memory was tested by free recall shortly after the second presentations or after retention intervals of up to I week. Recall of ...
متن کاملSpacing and lag effects in free recall of pure lists.
Repeating list items leads to better recall when the repetitions are separated by several unique items than when they are presented successively; the spacing effect refers to improved recall for spaced versus successive repetition (lag > 0 vs. lag = 0); the lag effect refers to improved recall for long lags versus short lags. Previous demonstrations of the lag effect have utilized lists contain...
متن کاملTwo components of long-term memory.
The existence of two independent components of long-term memory has been demonstrated by the authors. The evidence has been derived from the authors' findings related to the optimum spacing of repetitions in paired-associate learning. The two components are sufficient to explain the optimum spacing of repetitions as well as the spacing effect. Although the molecular counterparts of the two comp...
