A multi-step algorithm for serial order:Converg<strong>in</strong>g evidence from <strong>L<strong>in</strong>guistics</strong> and NeuroscienceCedric Boeckx1,2 & Anna Martínez-Álvarez21 ICREA & 2Universitat de BarcelonaThe present contribution aims to explore how serial order is computed <strong>in</strong> <strong>the</strong> humanm<strong>in</strong>d/bra<strong>in</strong> from a biol<strong>in</strong>guistic perspective (Lenneberg 1967; Chomsky 2005; Di Sciullo et al2010). To do so, <strong>the</strong> process of l<strong>in</strong>earization is decomposed <strong>in</strong>to three different computationalmechanisms described <strong>in</strong> a way that allows <strong>the</strong>ir implementation <strong>in</strong> <strong>the</strong> human bra<strong>in</strong>.Depart<strong>in</strong>g from a subdividision of Broca's area <strong>in</strong>to three different areas: pars opercularis,pars triangularis and frontal operculum (Friederici et al. 2003). The present work claims that<strong>the</strong>se three bra<strong>in</strong> areas play an important role <strong>in</strong> Language and, <strong>in</strong> particular, <strong>in</strong> <strong>the</strong> process ofl<strong>in</strong>earization converg<strong>in</strong>g with DM.As Lashley 1951 po<strong>in</strong>ted out, “<strong>the</strong> problems raised by <strong>the</strong> organization of languageseem to me to be characteristic of almost all o<strong>the</strong>r cerebral activity. There is a series ofhierarchies of organization; <strong>the</strong> order of vocal movements <strong>in</strong> pronounc<strong>in</strong>g <strong>the</strong> word, <strong>the</strong> orderof words <strong>in</strong> <strong>the</strong> sentence, <strong>in</strong> a discourse. Not only speech, but all skilled acts seem to <strong>in</strong>volve<strong>the</strong> same problems of serial order<strong>in</strong>g”. Lashley´s concern with serial order was also shared byRichard Kayne. Approach<strong>in</strong>g serialization of hierarchical organization from a l<strong>in</strong>guisticprespective, Kayne (1994) proposed that l<strong>in</strong>earization is a one-step process, that is,hierarchical relations give rise to l<strong>in</strong>ear order directly, via is L<strong>in</strong>ear Correspondence Axiom.The <strong>the</strong>oretical framework of Distributed Morphology (DM) assumes that syntax itselfgenerates and manipulates an unordered hierarchy of abstract syntactic features devoid ofphonological content, <strong>the</strong> so-called “morphemes” (Halle and Marantz 1993). Thephonological content of a morpheme is <strong>in</strong>serted postsyntactically. Unlike for Kayne, <strong>in</strong> DMl<strong>in</strong>earization would consist of a series of processes that realize <strong>the</strong> phonological content of ahierarchical representation. Follow<strong>in</strong>g <strong>the</strong> tenets of DM, Idsardi and Raimy (<strong>in</strong> press) offer adecomposition of <strong>the</strong> process of l<strong>in</strong>earization <strong>in</strong>to three different operations, as shown <strong>in</strong> (1):(1) L<strong>in</strong>earization processesModuleCharacteristicsNarrow syntax hierarchy, no l<strong>in</strong>ear order, no phonological contentLINEARIZATION-1 = ImmobilizationMorphosyntax hierarchy, adjacency, no phonological contentLINEARIZATION-2 = Spell-outMorphophonology no hierarchy, directed graph, phonological contentLINEARIZATION-3 = SerializationPhonologyno hierarchy, l<strong>in</strong>ear order, phonological str<strong>in</strong>gIn parallel to this development <strong>in</strong> l<strong>in</strong>guistics, <strong>the</strong> functional role of Broca's area hasbeen a focus of debate <strong>in</strong> <strong>the</strong> neurol<strong>in</strong>guistic field s<strong>in</strong>ce a very long time (Grodz<strong>in</strong>sky andSanti 2008; Rogalsky & Hickok 2011; a.o.). With <strong>the</strong> spread of neuroimag<strong>in</strong>g techniques,advances regard<strong>in</strong>g Broca's area have been made <strong>in</strong> <strong>the</strong> neuroscientific field. Broca's areaconstists of three different areas, namely pars triangularis (BA 44), pars triangularis (BA45)and <strong>the</strong> adjacent frontal operculum. The neural connectivity between Broca's areas and <strong>the</strong>temporal lobe is recently summarized <strong>in</strong> Rogalsky and Hickok (2011) and shown <strong>in</strong> (2):
