Children like dense neighborhoods: Orthographic neighborhood density effects in novel readers.

Previous evidence with English beginning readers suggests that some orthographic effects, such as the orthographic neighborhood density effects, could be stronger for children than for adults. Particularly, children respond more accurately to words with many orthographic neighbors than to words with few neighbors. The magnitude of the effects for children is much higher than for adults, and som...

Orthographic and Associative 1 PSYCHOPHYSIOLOGY, in press Running head: Orthographic and Associative Neighborhood Density Orthographic and Associative Neighborhood Density Effects: What is Shared, What is Different?

Words with many orthographic neighbors elicit a larger N400 than words with few orthographic neighbors. This has been interpreted as stronger overall semantic activation due to orthographic neighbors activating their semantic representations. To investigate this claim, we manipulated the number of associates of words (NoA), a variable directly affecting overall semantic activation, and compared...

The Impact of Semantic Neighborhood Density on Semantic Access

Theories of word recognition agree that multiple word candidates are activated and compete for recognition when a word is read or heard. Orthographic and phonological density metrics have provided significant, but partial, accounts of this activation and competition process. We extend this approach to examine the impact of semantic neighborhood density on visual semantic access. We compare meas...

Differentiating the effects of phonotactic probability and neighborhood density on vocabulary comprehension and production: a comparison of preschool children with versus without phonological delays.

PURPOSE To differentiate the effect of phonotactic probability from that of neighborhood density on a vocabulary probe administered to preschool children with or without phonological delays. METHOD Twenty preschool children with functional phonological delays and 34 preschool children with typical language development completed a 121-item vocabulary probe in both an expressive and receptive r...
