We investigate how the role of predictors in models of reaction times
in auditory lexical decision experiments depends on the operational
definition of RT: whether the time is measured from stimulus onset
or from stimulus offset. In a large body of literature, RTs are measured
from the onset of the stimulus to the start of the response (often
a button press or an oral response). The rationale behind this choice
is that information about the stimulus becomes available to the listener
starting at onset. Alternatively, the RT from offset is less dependent
on stimulus duration and is assumed to focus on those cognitive processes
that play a role late(r) in the word and after word offset, when all
information is available.
The paper presents
RT-onset and RT-offset-based linear mixed effects models for three
different lexical decision-based data sets and explains the significant
differences between these models, showing to what extent both definitions
of reaction time reveal different roles for predictors and how early
and later contributions to the overall RT can be differentiated.
