Letter typing times in milliseconds for four types of compounds investigated by Libben and Weber (2014). The morpheme boundary is considered to be position zero. Position minus two is thus two letters before the boundary, position minus one is the letter before, and position plus one is the letter immediately following the morphemic boundary. Thus, for the compound sailboat, positions minus two to plus two would comprise the letters “i,” “l,” “b,” and “o.” The time taken to type the letter at position plus one (e.g., the “b” in sailboat) is interpreted as the time taken to pause at the morpheme boundary.
