TL;DR: This article found that the mothers interacted with their infants using a conversational model, and that the changes in the mothers' speech reflect their children's growing ability to function as conversational partners.
Abstract: The speech of two mothers to their infants at several points between three and eighteen months of age was analysed. Simplicity of the speech, as measured by MLU, was about the same at all ages, and none of the other features of the mothers' speech style showed any abrupt change at the time the children started to talk. The changes that did occur started much earlier, at about seven months. These findings are incompatible with the explanation that mothers speak simply and redundantly in response to cues of attention and comprehension from the child listener. It is suggested that the mothers interacted with their infants using a conversational model, and that the changes in the mothers' speech reflect their children's growing ability to function as conversational partners.

TL;DR: In this article, Gut microbiota composition in early infancy and the subsequent development of atopic manifestations and sensitisation was examined, and the presence of Escherichia coli was associated with a higher risk of developing eczema (OR adj ǫ= 1.87; 95% CI 1.15 to 3.04).
Abstract: Background and aims: Perturbations in intestinal microbiota composition due to lifestyle changes may be involved in the development of atopic diseases. We examined gut microbiota composition in early infancy and the subsequent development of atopic manifestations and sensitisation. Methods: The faeces of 957 infants aged 1 month and participating in the KOALA Birth Cohort Study were analysed using quantitative real-time PCR. Information on atopic symptoms (eczema, wheeze) and potential confounders was acquired through repeated questionnaires. Total and specific IgE were measured in venous blood samples collected during home visits when the infant was 2 years old. During these home visits a clinical diagnosis of atopic dermatitis was made according to the UK-Working Party criteria. Results: The presence of Escherichia coli was associated with a higher risk of developing eczema (OR adj = 1.87; 95% CI 1.15 to 3.04), this risk being increased with increasing numbers of E coli (p for trend = 0.016). Infants colonised with Clostridium difficile were at higher risk of developing eczema (OR adj = 1.40; 95% CI 1.02 to 1.91), recurrent wheeze (OR adj = 1.75; 95% CI 1.09 to 2.80) and allergic sensitisation (OR adj = 1.54; 95% CI 1.02 to 2.31). Furthermore, the presence of C difficile was also associated with a higher risk of a diagnosis of atopic dermatitis during the home visit (OR adj = 1.73; 95% CI 1.08 to 2.78). Conclusion: This study demonstrates that differences in gut microbiota composition precede the development of atopy. Since E coli was only associated with eczema and C difficile was associated with all atopic outcomes, the underlying mechanisms explaining these association may be different.

TL;DR: A new explanation of the positive manifold based on a dynamical model is proposed, in which reciprocal causation or mutualism plays a central role, and it is shown that thepositive manifold emerges purely by positive beneficial interactions between cognitive processes during development.
Abstract: Scores on cognitive tasks used in intelligence tests correlate positively with each other, that is, they display a positive manifold of correlations. The positive manifold is often explained by positing a dominant latent variable, the g factor, associated with a single quantitative cognitive or biological process or capacity. In this article, a new explanation of the positive manifold based on a dynamical model is proposed, in which reciprocal causation or mutualism plays a central role. It is shown that the positive manifold emerges purely by positive beneficial interactions between cognitive processes during development. A single underlying g factor plays no role in the model. The model offers explanations of important findings in intelligence research, such as the hierarchical factor structure of intelligence, the low predictability of intelligence from early childhood performance, the integration/differentiation effect, the increase in heritability of g, and the Jensen effect, and is consistent with current explanations of the Flynn effect.

TL;DR: Analysis of the p63 gene, a homolog of p53 located in the critical LMS/EEC interval, revealed heterozygous mutations in nine unrelated EEC families that provide a molecular explanation for the dominant character of p63 mutations in EEC syndrome.
