Semantic Settling Dynamics (SSD) model predicts that polysemy effect would change as a
function of time spent in processing (Armstrong & Plaut, 2016). In early processing, the
processing advantage would be large (compared to unambiguous words), whereas later, the
effect would decrease. Research in Serbian described polysemy by quantitatively expressing
the magnitude of the ambiguity of a particular word through measures such as number of
senses (NoS). Such experiments revealed a facilitatory effect of polysemy in visual lexical
decision task (vLDT; Filipović Đurđević, 2007). In SSD framework, this effect would be the
equivalent of the early processing. Once the processing is prolonged, we expected reduction
of this effect, similar to previous findings comparing polysemy to unambiguous words. This
was demonstrated in experiments that employed the prolonging strategy of comparing vLDT
(early processing) and auditory lexical decision task (aLDT; late processing). When the
stimu...li were nouns, we found the expected facilitatory polysemy effect in vLDT and null
effect in aLDT (Mišić & Filipović Đurđević, 2019). Compared to the model predictions and
the previous research, this loss of effect in later processing was unexpected. Therefore, the
aim of this research was twofold – to extend the SSD testing on polysemous verbs and to
replicate the results we found on nouns. We tested whether the NoS effect would change in
the late processing by using the same prolonging strategy as in previous experiments.
Two groups of participants (71 in vLDT, 75 in aLDT) were presented with 100 polysemous
verbs in two versions of lexical decision task – visual and auditory. NoS was estimated based
on the senses listed in the Matica Srpska dictionary (2007). Linear mixed modelling revealed
that the aLDT was significantly slower than the vLDT. Marginal facilitatory NoS effect was
found in vLDT (β = -.020, S.E. = .010, df = 100.07, t = -1.934, p = .056). The interaction with
task modality was also marginally significant (β = .019, S.E. = .010, df = 98.84, t = -1.871,
p = .064).
Even though the NoS effect was marginally significant in both the baseline and the prolonged
processing condition, the trends point to the same pattern of the results as the ones previously
found. Early processing reveals a facilitatory effect, while in later processing, that effect is
attenuated. This is a partial replication of the findings from the noun experiment and together
they converge to the conclusion that the SSD model cannot give precise predictions regarding
the effect change.
