Naming a picture is more difficult in the context of a taxonomically-related picture. Disagreement exists on whether non-taxonomic relations, e.g., associations, have similar or different effects on picture naming. Past work has reported facilitation, interference and null results but with inconsistent methodologies. We paired the same target word (e.g., cow) with unrelated (pen), taxonomically-related (bear), and associatively-related (milk) items in different blocks, as participants repeatedly named one of the two pictures in randomized order. Significant interference was uncovered for the same target item in the taxonomic vs. unrelated and associative blocks. There was no robust evidence of interference in themore »
Behavioral interference or facilitation does not distinguish between competitive and noncompetitive accounts of lexical selection in word production.
One of the major debates in the field of word production is whether lexical selection is competitive or not. For nearly half a century, semantic interference effectsin picture naming latencieshave beenclaimed as evidence for competitive (relative threshold) models of lexical selection,while semantic facilitation effects have beenclaimed as evidence for non-competitive (simple threshold) models instead.In this paper, we use a computational modelingapproach to comparethe consequences of competitive and noncompetitive selection algorithms for blocked cyclic picture naming latencies, combined with two approaches to representing taxonomic and thematic semantic features.We show thatalthough our simplemodel can capture both semantic interference and facilitation,the presence or absence of competition in the selection mechanism is unrelated to the polarity of these semantic effects.These results question the validity of prior assumptions and offer new perspectives on the origins of interference and facilitation in languageproduction.

Do Cross-Language Script Differences Enable Bilinguals to Function Selectively When Speaking in One Language Alone?The present study examined the role of script in bilingual speech planning by comparing the performance of same and different-script bilinguals. Spanish-English bilinguals (Experiment 1) and Japanese-English bilinguals (Experiment 2) performed a picture-word interference task in which they were asked to name a picture of an object in English, their second language, while ignoring a visual distractor word in Spanish or Japanese, their first language. Results replicated the general pattern seen in previous bilingual picture-word interference studies for the same-script, Spanish-English bilinguals but not for the different-script, Japanese-English bilinguals. Both groups showed translation facilitation, whereas only Spanish-English bilinguals demonstrated semanticmore »
Picture-naming tasks provide critical data for theories of lexical representation and retrieval and have been performed successfully in sign languages. However, the specific influences of lexical or phonological factors and stimulus properties on sign retrieval are poorly understood. To examine lexical retrieval in American Sign Language (ASL), we conducted a timed picture-naming study using 524 pictures (272 objects and 251 actions). We also compared ASL naming with previous data for spoken English for a subset of 425 pictures. Deaf ASL signers named object pictures faster and more consistently than action pictures, as previously reported for English speakers. Lexical frequency, iconicity,more »
abstract A growing body of research shows that both signed and spoken languages display regular patterns of iconicity in their vocabularies. We compared iconicity in the lexicons of American Sign Language (ASL) and English by combining previously collected ratings of ASL signs (Caselli, Sevcikova Sehyr, Cohen-Goldberg, & Emmorey, 2017) and English words (Winter, Perlman, Perry, & Lupyan, 2017) with the use of data-driven semantic vectors derived from English. Our analyses show that models of spoken language lexical semantics drawn from large text corpora can be useful for predicting the iconicity of signs as well as words. Compared to English, ASLmore »
Advanced Second Language Learners of Mandarin Show Persistent Deficits for Lexical Tone Encoding in Picture-to-Word Form MatchingPeople who grow up speaking a language without lexical tones typically find it difficult to master tonal languages after childhood. Accumulating research suggests that much of the challenge for these second language (L2) speakers has to do not with identification of the tones themselves, but with the bindings between tones and lexical units. The question that remains open is how much of these lexical binding problems are problems of encoding (incomplete knowledge of the tone-to-word relations) vs. retrieval (failure to access those relations in online processing). While recent work using lexical decision tasks suggests that both may play a role,more »
