People talk a lot: a typical adult knows tens of thousands of words in their first language, thousands more in any additional languages they might speak, and continue to learn new words throughout their life.
The literature on language production agrees on the existence of three levels before the retrieval of a word: conceptualisation, formulation and articulation.
However, there is an inconclusive debate on how the correct word is chosen for selection, i.e. whether similar lexical representations (i.e. couch and sofa) compete (Levelt et al., 1999) or do not compete (Dell, 1986) before the selection of the target.
Most research on production has used psychologically complex designs to investigate these processes and has often interpreted population-level variables (i.e. name agreement in picture naming) as indexes of individual-level cognitive processes.
In this talk, I will argue that some of the effects that have previously been attributed to endogenous lexical competition may in fact reflect task-specific biases and that such predictors cannot always directly inform us about the processes that occur within the individual speaker.
Moreover, I will present Oppenheim, Dell and Schwart’s (2010) simple model of word production, as an error-driven implicit learning algorithm that operates on the task of meaning-driven word retrieval and report recent and ongoing behavioural and electrophysiological studies that support this idea.
