KVK trigram

from Wikipedia, the free encyclopedia

KVK trigrams or KVK combinations are primarily used in learning psychology and in memory tests, consisting of a consonant, a vowel and another consonant (KVK). They were first used in 1885 by the German psychologist Hermann Ebbinghaus . Ebbinghaus randomly assigned a certain answer to different trigrams and thus created learning lists that he used to examine his own learning ability. KVK trigrams are particularly suitable for examining learning performance because they are so-called low- meaning syllables that have no meaning. This is to ensure that a test person in an experiment or a memory test has no or only a weak association with a trigram if possible and that all trigrams and their answers in a learning list can be learned easily. Interference that could arise from an existing association should be eliminated in this way. Even Hermann Ebbinghaus recognized, however, that KVK trigrams are not completely meaningless syllables. Therefore, they can differ significantly in terms of how they can be learned or they can be learned differently by different test subjects. For example, the trigram MEL could remind a test person of flour and can therefore be learned differently than, for example, the trigram XUZ.
