Is the go/no-go lexical decision task an alternative to the yes/no lexical decision task?

In the go/no-go lexical decision task (LDT), participants are instructed to respond as quickly as they can when a word is presented and not to respond if a nonword is presented. By minimizing part of the response selection process in the experimental task, the impact of response decision time on the obtained lexical decision time is probably reduced relative to the standard yes/no LDT (Gordon, 1983). Experiments 1 and 2 show that the go/no-go LDT is sensitive to the effects of word frequency and associative priming--the magnitude of these effects is similar with the two tasks. More important, the go/no-go LDT has a number of advantages with respect to the "standard" yes/no LDT: It offers faster response times, more accurate responding, and fewer processing demands than does the yes/no task. Accordingly, the go/no-go task appears to be an excellent alternative to the standard yes/no task.

Masked priming effects with syllabic neighbors in a lexical decision task.

Four lexical decision experiments using a masked priming paradigm were conducted to analyze whether the previous presentation of a syllabic neighbor (a word sharing the same 1st syllable) influences recognition performance. The results showed an inhibitory effect of more frequent syllabic primes and some facilitation of nonword syllabic primes (Experiments 1-3). When monosyllabic pairs were used (Experiment 3), no priming effects of the 2 initial letters were found. Finally, when using only syllables as primes, latencies to words were shorter when preceded by primes that corresponded to the 1st syllable than by primes that contained 1 letter more or less than the 1st syllable (Experiment 4). Results are interpreted using activation models that take into account a syllabic level of representation.

Naming pseudowords in Spanish: effects of syllable frequency.

Three naming experiments were conducted to examine the role of the first and the second syllable during speech production in Spanish. Facilitative effects of syllable frequency with disyllabic words have been reported in Dutch and Spanish (Levelt & Wheeldon, 1994; Perea & Carreiras, 1998). In both cases, the syllable frequency effect was independent of-and additive to-the effect of word frequency. However, Levelt and Wheeldon (1994) found that words ending in a high-frequency syllable were named faster than words ending in a low-frequency syllable, whereas Perea and Carreiras (1998) found a facilitative effect of syllable frequency for the initial syllable. In Experiments 1-2, we manipulated the frequency of the first and the second syllable of disyllabic CV.CV pseudowords. In Experiment 3, participants named CVC disyllabic pseudowords for which only the frequency of the first syllable was manipulated. The experiments showed a facilitative effect of frequency of the first syllable. The findings are discussed in terms of the current models of speech production.
