Effects of morphology and semantic transparency on typing latencies in english compound and pseudocompound words.

We used a typing task to measure the written production of compounds, pseudocompounds, and monomorphemic words on a letter-by-letter basis to determine whether written production (as measured by interletter typing speed) was affected by morphemic structure and semantic transparency of the constituents. Semantic transparency was analyzed using a dichotomous classification (opaque vs. transparent) as well as participant ratings. Our results indicate that written production is sensitive to morphemic structure and to the semantic transparency of the first constituent. (PsycINFO Database Record
