“…It seems rather that a certain degree of productivity is needed in order for computational effects to arise (see Vannest, Bertram, Jä rvikivi, & Niemi, 2002), and productivity -as other affix specific characteristics -is likely to be tied together with a number of other factors, such as (orthographic) length, frequency, and ambiguity. Laudanna and Burani (1995) showed that affix length and both type and token frequency of the affix affect whether derivational affixes are used in the course of processing in Italian , for a review; Burani & Laudanna, 1992;Burani, Dovetto, Thornton, & Laudanna, 1997;Burani, Thornton, Iacobini, & Laudanna, 1995). More precisely, long and frequent affixes were more likely to act as processing units than short and infrequent affixes.…”
