Masked Repetition

The present study used event-related potentials (ERPs) to examine the time course of visual word recognition using a masked repetition priming paradigm. Participants monitored target words for occasional animal names, and ERPs were recorded to nonanimal critical items that were full repetitions, partial repetitions, or unrelated to the immediately preceding masked prime word. The results showed a strong modulation of the N400 and three earlier ERP components (P150, N250, and the P325) that we propose reflect sequential overlapping steps in the processing of printed words.

Participant Characteristics

The aim of this paper is to examine when signers start to recognize the lexical meaning of a sign. This is studied with movies of 32 mono-morphemic signs of Sign Language of the Netherlands (SLN). Signs were presented in isolation or with preceding fidgets (e.g., rubbing your nose). Signers watched these movies at normal playing speed and had to respond as soon as they recognized a sign, which they were able to do, on average, about 850 ms after the coded beginning of the sign. By subtracting the time participants need to generate a motor response to a visible event, which was 310 ms on average, sign recognition was estimated to occur after around 540 ms. The results were further analyzed in relation to the sign’s movement phases (preparation, nucleus, and recovery) and for effects of participant characteristics, sign characteristics, and embedding conditions. The current findings are compared with earlier work on the time course of lexical sign recognition. Moreover, they are compared with findings from an earlier experiment on detecting the beginning of a sign (Arendsen et al., 2007) to study possible interference of lexical recognition with sign detection by signers.

The Impact

In three experiments, we assessed the impact of auditory homophone primes (/swi:t/) on lexical decisions to visually presented low-frequency (suite) and high-frequency (sweet) homophone spellings. In Experiment 1 we investigated the time course of these cross-modal repetition priming effects. Results suggested that low-frequency homophone spellings do not reach the same activation level as nonhomophones, even at long SOAs. There were no differences in priming between high-frequency homophones and nonhomophones. In Experiments 2 and 3 we attempted to eliminate the impact of strategies with lower proportions of repetition primes. Results showed smaller priming effects for both low- and high-frequency homophones than for nonhomophones, suggesting that neither homophone spelling is fully activated. Implications for local and distributed models of word recognition are discussed.
