Dependent variable are single-trial means in the time window 300–500 ms from stimulus onset using only subjects and (direct) objects. For animacy and position, the coefficients are named for the dispreferred condition (note the minus sign) and represent the contrast dispreferred > mean.” Morphology also has an additional “neutral” level for ambiguous case marking, and so the coefficients represent the contrast from the respective marked conditions (note the minus and plus signs for dispreferred/unambiguous accusative and preferred/unambiguous nominative) to the (grand) mean.
