2 In cognitive psychology, an improvement in memory for material or performance of a task some time after learning it, compared to the level of performance immediately after learning, especially when the learning was carried out by massed practice. The concept was introduced in 1913 by the Welsh schoolteacher Philip Boswood Ballard (1865–1950), who reported that schoolchildren who memorized passages of poetry and were tested repeatedly for periods up to a week could often recall lines on later tests that they could not recall on earlier tests. Ballard contrasted this phenomenon with obliviscence. Reminiscence of some items of information can be offset by forgetting of others, so that the overall performance may not improve over time; however, under some conditions there may be an overall gain in performance over successive tests, in which case the phenomenon is called hypermnesia.
