This paper presents the results of a comprehensive meta-analysis of 82 word production experiments. The analysis focused on both the spatial overlap of activated regions and the time course of activations. The study identified specific regions and time windows for core word production processes: lexical selection, phonological code retrieval, syllabification, and phonetic/articulatory preparation. The findings were compared with studies on auditory word/non-word perception and reading, showing that the time course of activations in word production is compatible with the temporal constraints of perception processes in picture/word interference paradigms. The study outlines the functional organization of word production, involving a neural network with left-lateralized activation for core processes. The LRM theory, which underpins the analysis, describes the sequential stages of spoken word production, including conceptual preparation, lemma retrieval, form encoding, and phonetic encoding. The time course of these processes was analyzed, with specific time windows identified for each stage. For example, conceptual preparation occurred within 150–200 ms post picture onset, lemma retrieval within 100–150 ms, and form encoding within 217–530 ms. The study also examines the relationship between word production and perception networks, highlighting the integration of these systems. The results suggest that the time course of activations in word production is compatible with the temporal constraints of perception processes. The meta-analysis identified cerebral regions involved in word production and perception, showing that these regions are active in both tasks. The study also discusses the reliability of these findings, considering the variability in experimental techniques and the need for conservative criteria in interpreting results. Overall, the study provides a detailed understanding of the spatial and temporal signatures of word production components, highlighting the complex interplay between perception and production in language processing.This paper presents the results of a comprehensive meta-analysis of 82 word production experiments.
