Picture-name priming in the cerebral hemispheres: evidence for phonological access in the right hemisphere.

This study investigated right hemisphere involvement in access to phonology, using a picture-naming priming paradigm where pictures and names of common objects printed in Japanese Kana were presented in succession to the same visual field or different visual fields with a stimulus onset asynchrony of 250 msec. A naming task was used for this purpose. The result showed that, when primes and targets were presented to the same visual field, facilitation for related pairs was observed in each hemisphere, with overall naming latencies being slower in the right hemisphere than in the left hemisphere.

Access to concrete word meanings in the cerebral hemispheres: facilitation and inhibition effects.

In 2002 Shibahara and Lucero-Wagoner, using a priming paradigm, reported a larger facilitation for concrete noun pairs in the right than left hemisphere when the stimulus onset asynchrony was 250 msec. Their related prime-target pairs were similar not only in meaning but also perceptual attributes, such as shape. They had reported such perceptual information to be available only in the right hemisphere early in target processing.

Semantic effects in word naming: evidence from English and Japanese Kanji.

Three experiments investigated whether reading aloud is affected by a semantic variable, imageability. The first two experiments used English, and the third experiment used Japanese Kanji as a way of testing the generality of the findings across orthographies. The results replicated the earlier findings that readers were slower and more error prone in reading low-frequency exception words when they were low in imageability than when they were high in imageability (Strain, Patterson, & Seidenberg, 1995).

Variables affecting naming latency for Japanese Kanji: a re-analysis of Yamazaki, et al. (1997).

Yamazaki, Ellis, Morrison, and Lambon Ralph in 1997 demonstrated that written and spoken age-of-acquisitions had a stronger effect on the naming latency of single Kanji words than any other variable including familiarity. The present study was designed to reanalyze Yamazaki, et al.'s data, using the ratings of written and spoken age-of-acquisitions and visual and auditory familiarities taken from the NTT lexical database.

Hemispheric asymmetry in accessing word meanings: concrete and abstract nouns.

The present experiments investigated hemispheric differences in the brain in accessing concrete and abstract word meanings. For this purpose, an automatic semantic priming paradigm was used with a short stimulus onset asynchrony between prime and target (250 msec.) as well as a low proportion of related trials (20%).
