This study reports 4 experiments that investigated the locus of temporal ef
fects of printed word frequency in speeded-naming tasks. Response latencies
and onset durations are shorter for high-frequency words compared with low
-frequency words, but there is no effect of frequency on rime durations. Th
ese results can only be accounted for if (a) phonemes are activated in para
llel and not sequentially from left to right and (b) the criterion to initi
ate pronunciation is based on the initial phoneme and not the whole word. I
n addition, the effect of word-initial phoneme characteristics on acoustic
latency was investigated. The acoustic latency of words beginning with voic
eless sibilants was less than that of words beginning with plosives, a patt
ern opposite that reported by R. Treiman, J. Mullennix, R. Bijeljac-Babic,
and E. E. Richmond-Welty (1995). This difference was attributed to the lowe
r sensitivity of voice keys compared with measures based on digitized respo
nses.
