Children’s Learning of a Semantics-Free Artificial Grammar with Center Embedding
No full textWhether non-human animals have an ability to learn and process center embedding, a core property of human language syntax, is still debated. Artificial-grammar learning (AGL) has been used to compare humans and animals in the learning of center embedding. However, up until now, human participants have only included adults, and data on children, who are the key players of natural language acquisition, are lacking. We created a novel game-like experimental paradigm combining the go/no-go procedure often used in animal research with the stepwise learning methods found effective in human adults’ center-embedding learning. Here we report that some children succeeded in learning a semantics-free artificial grammar with center embedding (A2B2 grammar) in the auditory modality. Although their success rate was lower than adults’, the successful children looked as efficient learners as adults. Where children struggled, their memory capacity seemed to have limited their AGL performance
Attention To People Like You: A Proposal Regarding Neuroendocrine Effects on Linguistic Variation
No full textAlthough the literature on language change has often replicated and discussed a pattern in which female speakers lead in changes that occur below the level of awareness, there is no consensus on why this pattern should arise. Interestingly, recent findings in endocrinology show that differences in prenatal testosterone exposure can impact learning patterns. In the light of these findings, we first present preliminary results consistent with the hypothesis that a biological factor, prenatal exposure to androgens, can have a small, continuous biasing effect on linguistic variation, namely the variable duration of pre-aspiration conditioned by voiceless obstruents in Tyneside English. Second, we propose an explanatory model in which the biological factor—prenatal testosterone exposure—creates subtle bias in how speakers learn linguistic variants and suggest that some reported sex effects are derivative. This model is compatible with the high tendency for females to lead in language change from below (Labov 1990: 206)
The Relationship between Phoneme Production and Perception in Speech-Impaired and Typically-Developing Children
No full textOne of the central questions that Eric Lenneberg raised in his seminal book, Biological Foundations of Language is: What is the relationship between language comprehension and language production? This paper reviews Lenneberg’s case study of a child with congenital anarthria and then presents the results of two studies that investigate the relationship between phoneme perception and production. The first study investigates the phoneme identification skills of a child with developmental apraxia who, like the anarthric child studied by Lenneberg, had essentially no speech yet had no difficulty understanding speech. The second study investigates the extent to which 28 typically-developing children’s ability to identify phonemes is related to their ability to produce phonemes. The results of both studies support Lenneberg’s conclusion that children’s ability to perceive speech is not dependent on their ability to produce speech. Thus, Lenneberg’s original case study and the two studies presented in this paper argue against gestural theories of speech perception such as the Motor Theory
Merge and Labeling as Descent with Modification of Categorization: A Neo-Lennebergian Approach
No full textPhi-Features in Animal Cognition
No full textThis paper argues that the core phi-features behind grammatical person, number, and gender are widely used in animal cognition and are in no way limited to humans or to communication. Based on this, it is hypothesized (i) that the semantics behind phi-features were fixed long before primates evolved, (ii) that most go back as far as far as vertebrates, and (iii) that some are shared with insects and plants
Justifications for a Discontinuity Theory of Language Evolution
No full textIn Chapter 6 of Biological Foundations of Language, Lenneberg argues against continuity theories of language evolution, which claim that language evolved from simpler communication systems. Although Lenneberg was pessimistic about even discontinuity theories explaining how language evolved, discontinuity has become significant in the Minimalist program, which posits that our species’ acquisition of Merge was the key discontinuity that made language possible. On the basis of a unified description of natural communication systems, I show that language is indeed based upon a cognitive discontinuity, which is moreover specific to linguistic ability. However, I argue that even Minimalist theories must recognise this discontinuity as the sensorimotor interface with syntax, rather than syntax itself. This ultimately supports the view that syntactic structures are structures of thought, but taking this claim seriously means reimagining how syntax relates to semantics and morphology, as the traditional ‘lexical item’ is no longer a tenable primitive of generative theory
