Exposure—meaning; Experimental Evidence The f i r s t e x p e r i m e n t a l study on the r e l a t i o n s h i p between exposure and word meaning was c a r r i e d out by Johnson, Thomson, and F r i n c k e ( 1 9 6 0 ) . These authors f i r s t asked Ss t o r a t e a number of nonsense words on the GOOD-BAD s c a l e o f the semantic d i f f e r e n t i a l . t h a t " t h i s i s an experiment The S s were then i n s t r u c t e d concerning the e f f e c t i v e n e s s o f r e p e t i t i o n i n l e a r n i n g t o pronounce strange words c o r r e c t l y . " Some o f these words were shown once, others t w i c e , f i v e t i m e s , o r t e n times. Ss were r e - q u i r e d t o look a t t h e s e words and t o pronounce them on each p r e s e n t a t i o n . F o l l o w i n g t h i s t r a i n i n g procedure the words were again r a t e d on the GOOD-BAD s c a l e . A s i g n i f i c a n t exposure e f f e c t was obtained by Johnson, Thomson, and F r i n c k e , with the words shown f r e q u e n t l y i n c r e a s i n g on the e v a l u a t i v e s c a l e . S t r a n g e l y , however, words which were seen only once i n t r a i n i n g were judged afterwards not q u i t e as "GOOD" as before Zajonc 22. training. Thus, as a r e s u l t of two, f i v e , and t e n exposures words im- proved i n meaning, and as a r e s u l t of but one exposure they d e t e r i o r a t e d . T h i s r e s u l t might be an a r t i f a c t of the b e f o r e - a f t e r procedure used by Johnson, Thomson, and F r i n c k e . Our experiment used the same s t i m u l i which, i n c i d e n t a l l y , came from the f a m i l i a r experiment by Solomon and Postman (1952) on the e f f e c t s of word frequency on r e c o g n i t i o n t h r e s h o l d . The s p e c i f i c experimental aims were a l s o t h e same as those of Johnson, Thomson, and F r i n c k e . our design d i f f e r e d from t h e i r s i n s e v e r a l r e s p e c t s . But I n the Johnson4 Thomson-Frincke experiment the same words always appeared i n the same frequencies t o a l l S s . Thus, the word JANDAR^, f o r i n s t a n c e , was given t e n times to each S_, and the word MECBURI was given once t o each S. It i s p o s s i b l e t h a t the e f f e c t s t h e s e authors obtained are not due t o the frequency manipulation a l o n e , but t h a t they depend on the s t i m u l u s m a t e r i a l w i t h which the frequency v a r i a b l e was f u l l y confounded. I n our study words and t r a i n i n g f r e q u e n c i e s were, t h e r e f o r e , counterbalanced i n a l a t i n square design. Because words and the number of exposures were counterbalanced an a f t e r - o n l y design c o u l d be employed, r e q u i r i n g no pre-measures. The e f f e c t s of repeated exposure could be observed by comparing f o r each word the f a v o r a b i l i t y r a t i n g i t r e c e i v e d a f t e r having been exposed during t r a i n i n g once, t w i c e , f i v e t i m e s , e t c .
