Apart from their remarkable phonological skills young infants prior to their first birthday show ability to match the mouth articulation they see with the speech sounds they hear. They are able to detect the audiovisual conflict of speech and to selectively attend to articulating mouth depending on audiovisual congruency. Early audiovisual speech processing is an important aspect of language development, related not only to phonological knowledge, but also to language production during subsequent years. Th is article reviews recent experimental work delineating the complex developmental trajectory of audiovisual mismatch detection. Th e central issue is the role of age-related changes in visual scanning of audiovisual speech and the corresponding changes in neural signatures of audiovisual speech processing in the second half of the first year of life. Th is phenomenon is discussed in the context of recent theories of perceptual development and existing data on the neural organisation of the infant ‘social brain’.

In Japanese, numeral classifiers-or measure words-co-occur with numbers in counting phrases. Th e present study characterized parent numeral classifier use and its relation to children’s classifier acquisition and number learning. Twenty-four Japanese-speaking parents and their two- to six-year-old children viewed and talked about two wordless picture books about counting to each other. Children also participated in a Counting task and Give-N task. Results revealed (1) parents’ classifier use changed in relation to children’s age and classifier use, and (2) parents’ increased use of specific classifiers was uniquely associated with children’s number understanding. These results suggest that aspects of children’s language and numerical development are related to parents’ language input, demonstrating the importance of examining the relation between language and cognition in a developmental context.

Little is known about the acquisition of another language modality on second language (L2) working memory (WM) capacity. Differential indexing within the WM system based on language modality may explain differences in performance on WM tasks in sign and spoken language. We investigated the effect of language modality (sign versus spoken) on L2 WM capacity. Results indicated reduced L2 WM span relative to first language span for both L2 learners of Spanish and American Sign Language (ASL). Importantly, ASL learners had lower L2 WM spans than Spanish learners. Additionally, ASL learners increased their L2 WM spans as a function of proficiency, whereas Spanish learners did not. This pattern of results demonstrated that acquiring another language modality disadvantages ASL learners. We posited that this disadvantage arises out of an inability to correctly and efficiently allocate linguistic information to the visuospatial sketchpad due to L1-related indexing bias.

This paper models conventionalisation of language structure as constitutive of processing fluency. I postulate that the difference in conventionalisation of linguistic forms used for communication significantly influences our reasoning about linguistically-expressed problems. Two studies are reported that tested this hypothesis with the use of variably conventionalised - fluent and disfluent - formulations of problem-solving tasks. Th e findings indicate that even in tasks requiring analytic reasoning, the degree to which the linguistic forms employed to communicate are conventionalised is correlated with the subjects’ performance success rate. On a more general level, this paper seeks to empirically address the nature of links between linguistic form and meaning construction.

Initiated by Davis and Knowles (1999), the-disrupt-then-reframe technique is based on the linking of two moments in time. First of all, slipping an unexpected element into a communication situation that is likely to provoke a disruption in communication. Once this disruption has been achieved, proposing a target behaviour by insisting on the benefit that the individual could derive from it. We wanted to verify that this technique, effective in American, Dutch, and Polish contexts and naturally dependent on the culture of individuals and the communication norms which prevail there, could be effective in a French context. In accordance with the literature, our results show that when the two phases of the technique are linked, a greater persuasive effect is observed. A theoretically interesting way to interpret the effectiveness of the technique is proposed.
