Outstanding long-term face recognition of suspects is a hallmark of the exceptionally skilled police 'super-recognisers' (SRs). Yet, research investigating SR's memory for faces mainly employed brief retention intervals. Therefore, in Experiment 1, 597 participants (121 SRs) viewed 10 target videos and attempted identification of targets from 10…

Thirty-six nonmusicians practiced a five-element key-press sequence on a digital piano, repeating the sequence as quickly and accurately as possible during twelve 30-s practice blocks alternating with 30-s pauses. Twelve learners rested for 5 min between Blocks 3 and 4, another 12 learners rested for 5 min between Blocks 9 and 10, and the…

By balancing the spacing effect against the effects of recency and frequency, this paper explains how practice may be scheduled to maximize learning and retention. In an experiment, an optimized condition using an algorithm determined with this method was compared with other conditions. The optimized condition showed significant benefits with…

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…
