dc.description.abstract
Effects of stimulus length on reaction times (RTs) in the lexical decision
task are the topic of extensive research. While slower RTs are consistently
found for longer pseudo-words, a finding coined the word length effect (WLE),
some studies found no effects for words, and yet others reported faster RTs
for longer words. Moreover, the WLE depends on the orthographic transparency
of a language, with larger effects in more transparent orthographies. Here we
investigate processes underlying the WLE in lexical decision in German-English
bilinguals using a diffusion model (DM) analysis, which we compared to a
linear regression approach. In the DM analysis, RT-accuracy distributions are
characterized using parameters that reflect latent sub-processes, in
particular evidence accumulation and decision-independent perceptual encoding,
instead of typical parameters such as mean RT and accuracy. The regression
approach showed a decrease in RTs with length for pseudo-words, but no length
effect for words. However, DM analysis revealed that the null effect for words
resulted from opposing effects of length on perceptual encoding and rate of
evidence accumulation. Perceptual encoding times increased with length for
words and pseudo-words, whereas the rate of evidence accumulation increased
with length for real words but decreased for pseudo-words. A comparison
between DM parameters in German and English suggested that orthographic
transparency affects perceptual encoding, whereas effects of length on
evidence accumulation are likely to reflect contextual information and the
increase in available perceptual evidence with length. These opposing effects
may account for the inconsistent findings on WLEs.
