In a production by typing task, with extraneous factors (e.g., length) controlled, measures such as latency to initialkeystroke as well as mean inter keystroke interval typically vary systematically according to the word’s lexical properties.Conventionally, lexical effects in production tasks get interpreted as evidence of cascaded processing between central andperipheral levels. We compare mean and distribution of keystroke latencies within the same stem as it undergoes affixation insets such as DEPRESS, DEPRESSION, DEPRESSIVE. Novel is the comparison of stems that differ with respect to number ofaffixes like SUPER, SUPERIOR, SUPERIORITY. Results provide new insights into the ways in which morphological structurecan influence purportedly peripheral motor processing.
