Steven Mithen argues that language evolved from an antecedent he terms “Hmmmmm, [meaning it was] Holistic, manipulative, multi-modal, musical and mimetic”. Owing to certain innate and learned factors, a capacity for segmentation and cross-stream mapping in early Homo sapiens broke the continuous line of Hmmmmm, creating discrete replicated units which, with the initial support of Hmmmmm, eventually became the semantically freighted words of modern language. That which remained after what was a bifurcation of Hmmmmm arguably survived as music, existing as a sound stream segmented into discrete units, although one without the explicit and relatively fixed semantic content of language. All three types of utterance – the parent Hmmmmm, language, and music – are amenable to a memetic interpretation which applies Universal Darwinism to what are understood as language and musical memes. On the basis of Peter Carruthers’ distinction between ‘cognitivism’ and ‘communicativism’ in language, and William Calvin’s theories of cortical information encoding, a framework is hypothesized for the semantic and syntactic associations between, on the one hand, the sonic patterns of language memes (‘lexemes’) and of musical memes (‘musemes’) and, on the other hand, ‘mentalese’ conceptual structures, in Chomsky’s ‘Logical Form’ (LF).

Sign languages like British Sign Language (BSL) include partially lexicalized constructions depicting object handling or manipulation – handling constructions. Object sizes gradiently vary, yet it is unclear whether handling handshapes depict handled objects categorically or gradiently. This study investigates the influence of sign language experience on perception of handling handshapes. Deaf signers and hearing non-signers completed perceptual handshape identification and discrimination tasks. We examined whether deaf BSL signers perceived handshape continua categorically or continuously compared with hearing non-signers, and whether reaction times were modulated by linguistic representations. The results revealed similar binary categorization of dynamically presented handling handshapes as deaf and hearing perceivers displayed higher discrimination accuracy on category boundaries, and lower, but above chance, within-category discrimination, suggesting that perceptual categorization was not uniquely mediated by linguistic experience. However, RTs revealed critical differences between groups in processing times; deaf signers’ RTs reflected stronger category bias and increased sensitivity to boundaries, suggesting underlying linguistic representations. Further, handshape variability within categories influenced deaf signers’ discrimination RTs in a manner that suggested graded category organization, with handshape prototype grounding the category. These findings provide an insight into the internal organization of handling handshapes and highlight the complex relationship between sign language, cognition, and gesture.

Usage-based (UB) accounts conceive of language learning as continuous, locally contingent construction learning, i.e., a lifelong process of developing and honing the repertoire of constructional patterns geared to the optimization of a language user’s communicative ability across a wide range of language domains. The continuous nature of the process entails that a full UB model needs to account for not only the dynamics of language learning at early stages of acquisition, but also the functionally motivated adaptations of the language system at more advanced levels of proficiency. We present a design based on naturalistic second language (L2) written productions that sets out to reconstruct the states of constructional knowledge of advanced L2 learners through the statistical analysis of their productions. Irrespective of theoretical framing, the study provides foundational data relevant for any property theory of language learning, i.e., any theory that is concerned with the nature of the language system to be acquired, which logically precedes a transition theory of the developmental processes of L2 acquisition.

The aim of this study was to test that the ability to obtain information about more than one letter at a glance develops prior to conventional reading. This study included 55 Dutch-speaking prereaders (mean age 63.56 months, SD = 6.55) and 45 Hebrew-speaking prereaders (mean age = 66.71 months, SD = 8.35). In a perceptual span task, one letter was projected in the fovea, the other to the right or to the left, at a distance of 4 or 6 letters from the center letter. A second perceptual span task included letter-like forms instead of letters. Eye-tracking was used to control whether children fixated on the center letter or letter-like form during the task. Obtaining information about two letters/forms was easier when the parafoveally projected letter/form was projected to the right for both Hebrew and Dutch children. Hemispheric dominance and not the dominant reading direction (right to left in Hebrew and left to right in Dutch) may explain this preference for right, which may mean that left-to-right reading is easier to learn than right-to-left reading. We did find, nevertheless, some evidence that reading direction in the dominant orthography affected how children divided attention over letters.

The present study was concerned with the question whether comprehension is based on mental simulation processes beyond the word level. In Experiment 1, participants were presented with coherent sentence pairs, consisting of a context sentence and a target sentence. Target sentences ended with a word referring to an entity with a typical location in the upper vertical space (e.g., bird in There she sees a bird). Context sentences either supported the target entity’s typical location or not (Anna looks to the sky vs. Anna looks to the ground, respectively). Participants responded to the final word of the sentence pair by pressing an up- or a down-key. The results showed a main effect of response direction (faster up compared to down responses) as well as an interaction between context location and response direction. In Experiment 2, participants were presented with incoherent sentence pairs with the same context sentences and different target sentences (whereby the target word was kept identical), but in an incoherent manner (target sentence: On the poster one sees a bird). Here, the results showed a main effect of response direction but no interaction. The same result was obtained in Experiment 3, in which participants were presented with word pairs consisting of an up- or down-context word (e.g., sky vs. ground) and an up-target word (e.g., bird). Overall, the results provide evidence for the view that comprehension involves simulation processes at the word level as well as simulation processes at the sentence or discourse level.
