The benefit of stimulus variability for generalization of acquired skills and knowledge has been shown in motor, perceptual, and language learning but has rarely been studied in reading. We studied the effect of variable training in a novel language on reading trained and untrained words.

Sixty typical adults received 2 sessions of training in reading an artificial script. Participants were assigned to 1 of 3 groups: a variable training group practicing a large set of 24 words, and 2 nonvariable training groups practicing a smaller set of 12 words, with twice the number of repetitions per word.

The stimulus set consisted of 36 nonwords written in an artificial script, previously used in Bitan & Booth (2012), in which a pair of symbols represents one letter, and six symbols in different permutations create all six letters of the alphabet. All nonword were composed of two consonants and one vowel in all possible syllable structures (CVC, VCC, CCV).
