In schema-based source monitoring, people mistakenly predict better source memory for expected sources (e.g., oven in the kitchen; "expectancy effect"), whereas actual source memory is better for unexpected sources (e.g., hairdryer in the kitchen; "inconsistency effect"; Schaper et al., 2019b). In three source-monitoring…

Despite the clear long-term benefits of spaced practice, students and teachers often choose massed practice. Whether learners actually fail to appreciate the benefits of spacing is, however, open to question. Early studies (e.g., Zechmeister & Shaughnessy, 1980) found that participants' judgments of learning were higher after massed than after…

We examined associative and item recognition using the maintenance rehearsal paradigm. Our intent was to control for mnemonic strategies; to produce a low, graded level of learning; and to provide evidence of the role of attention in long-term memory. An advantage for low-frequency words emerged in both associative and item recognition at very low…

The reconsolidation hypothesis states that a consolidated memory could again become unstable and susceptible to facilitation or impairment for a discrete period of time after a reminder presentation. The phenomenon has been demonstrated in very diverse species and types of memory, including the human procedural memory of a motor skill task but not…

The relation of arousal to retention in free learning was studied in a 3 x 2 design employing 48 undergraduates as Ss, three list conditions (high arousal, low arousal, mixed list) and two retention intervals (immediate and 3 days). Arousal value of the words was based on earlier studies. Contrary to previous paired-associate studies, no…

In three experiments employing 60 Ss, arousal was manipulated by white noise during paired-associate, serial, and free learning in an effort to investigate the relationships of arousal and long-term recall. Previous research suggested that high arousal in the paired-associate paradigm leads to better retention relative to low arousal. The present…

This research on factors influencing verbal learning and retention has used new techniques, attacked new problems, and tested new theories while trying to keep the experiments systematic. Studies conducted involved (1) the effect of varying the length of the intertrial interval on the learning and retention of different types of learning tasks;…
