Semantic Priming in Monolingual Russian and Bilingual Russian (L1)-English (L2) Speakers in a Single Word Naming Task

Identifying and exploring factors that influence bilingual language processing has been the topic of much psycholinguistic research. Semantic priming is typically used to examine semantic processing and refers to the phenomenon in which semantically related items (doctor-nurse) are processed faster and more accurately than semantically unrelated items (doctor-butter). The aim of the chapter is to address two key questions: 1) how the two languages of a bilingual are organised or stored and 2) how the two languages are processed. A review of the literature shows that there are currently no theoretical frameworks that explain Russian monolingual or Russian (L1)-English (L2) bilingual storage or processing. Monolingual Russian speakers and bilingual Russian (L1)-English (L2) speaking university students were asked to name target words under related or unrelated conditions. The results show that the magnitude of the semantic priming effect was determined by L2 proficiency. The implications for these findings is discussed within the current bilingual theoretical models.

Out-of-vocabulary but not meaningless: Evidence for semantic-priming effects in pseudoword processing

Non-arbitrary phenomena in language, such as systematic association in the form-meaning interface, have been widely reported in the literature. Exploiting such systematic associations previous studies have demonstrated that pseudowords can be indicative of meaning. However, whether semantic activation from words and pseudowords is supported by the very same processes, activating a common semantic memory system, is currently not known. Here, we take advantage of recent progresses from computational linguistics models allowing to induce meaning representations for out-of-vocabulary strings of letters via domain-general associative-learning mechanisms applied to natural language. We combined these models with data from priming tasks, in which participants are showed two strings of letters presented sequentially one after the other and are then asked to indicate if the latter is a word or a pseudoword. In Experiment 1 we re-analyzed the data of the largest behavioral database on semantic priming, while in Experiment 2 we ran an independent replication on a new language, Italian, controlling for a series of possible confounds. Results were consistent across the two experiments and showed that the prime-word meaning interferes with the semantic pattern elicited by the target pseudoword (i.e., at increasing estimated semantic relatedness between prime word and target pseudoword, participants’ reaction times increased and accuracy decreased). These findings indicate that the same associative mechanisms governing word meaning also subserve the processing of pseudowords, suggesting in turn that human semantic memory can be conceived as a distributional system that builds upon a general-purpose capacity of extracting knowledge from complex statistical patterns.

SPAML: Semantic Priming Across Many Languages

Semantic priming has been studied for nearly 50 years across various experimental manipulations and theoretical frameworks. These studies provide evidence of cognitive underpinnings of the structure and organization of semantic representation in both healthy and clinical populations. In this registered report, we propose to create a large database of semantic priming values, alleviating the sample size and limited language issues with previous studies in this area. Consequently, this database will include semantic priming data across multiple languages using an adaptive sampling procedure. This study will test the size of semantic priming effect and its variability across languages. Results will support semantic priming when reduced response latencies are found for related word-pair conditions in comparison to unrelated word-pair conditions. Differences in semantic priming across languages will be supported when priming effect confidence intervals do not overlap.

The status of conventional metaphorical meaning in the L2 lexicon

This paper investigates how L2 speakers of English process conventional metaphorical expressions. While much of the literature on L2 processing of figurative expressions focuses on idioms only, the aim of this paper is to investigate how L2 speakers process conventional metaphorical expressions. The results of a cross-modal semantic priming task show that conventional metaphors have a special status in comparison to literal language in the L2 lexicon. The differences in reaction times show that L2 speakers are aware of the connections between literal primes and targets, resulting in slower reaction times, while this effect is not found in the metaphorical condition. This demonstrates that even when metaphorical language is very conventional, it can cause difficulties for L2 speakers. Furthermore, these results show that conventional metaphorical expressions can pose a semantic and pragmatic challenge for language learners, thus creating a need for explicit teaching of metaphorical meanings of polysemous words.
