Infant vocalizing and phenotypic outcomes in autism: Evidence from the first 2 years

Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White; collected from 2007 to 2017 near Philadelphia) were analyzed at 6, 12, and 24 months. At 12 months, HR-ASD infants produced fewer vocalizations than HR-Neg infants. From 6 to 24 months, HR-Neg infants demonstrated steeper vocalization growth compared to HR-ASD and LR infants. Finally, among HR infants, vocalizing at 12 months was associated with language, social phenotype, and diagnosis at age 2. Infant vocalizing is an objective behavioral marker that could facilitate earlier detection of ASD.     

Decolonising curriculum practice: developing the indigenous cultural capability of university graduates

Higher Education - The pedagogical urge to decolonise student thinking has been at the heart of the drive to embed Indigenous knowledge in universities throughout the western world. Despite ongoing...     

Writing week-journals to improve the writing quality of fourth-graders’ compositions

Students’ writing problems are a global educational concern and is in need of particular attention. This study aims to examine the impact of providing extra writing opportunities (i.e., writing journals) on the quality of writing compositions. A longitudinal cluster-randomized controlled design using a multilevel modeling analysis with 182 fourth grade students was conducted. We examined whether students’ writing quality differed when writing journals on a weekly basis for 12 weeks, compared with a control group. Three covariates were analyzed, namely: (i) the students’ attitudes towards writing; (ii) their self-efficacy in writing; (iii) and their use of self-regulation (SRL) strategies while writing. Findings have shown that students who wrote week-journals significantly improved the writing quality of their compositions and reported a higher use of SRL strategies in writing. Nevertheless, self-efficacy and attitude towards writing were found to not be related to the quality of the compositions. Moreover, data indicated that the writing quality of compositions improved along with the writing quality of the week-journals. Findings suggest the use of week-journals in class to promote writing.     

Making the Pap smear into the "right tool" for the job

Despite being a rather recalcitrant tool, the "Pap smear" is today the major cancer screening technology in the world. This paper examines how and why hetrogeneous actors chose to advocate the Pap smear as a screen for cervical cancer in the late 1940's, and to tinker both in and far beyond the diagnostic laboratory for over 50 years to make the Pap smear "fit" as a screening and clinical technology. Tinkerings included gendering the division of labour, attempting to automate reading of smears, juggling costs, exploring alternative screening technologies, pushing for regulation of laboratories, and settling for locally-negotiated orders of clinical accuracy instead of global standardization, still elusive today.     

Can Children With Autism Spectrum Disorders “Hear” a Speaking Face?

This study used eye-tracking methodology to assess audiovisual speech perception in 26 children ranging in age from 5 to 15 years, half with autism spectrum disorders (ASD) and half with typical development. Given the characteristic reduction in gaze to the faces of others in children with ASD, it was hypothesized that they would show reduced influence of visual information on heard speech. Responses were compared on a set of auditory, visual, and audiovisual speech perception tasks. Even when fixated on the face of the speaker, children with ASD were less visually influenced than typical development controls. This indicates fundamental differences in the processing of audiovisual speech in children with ASD, which may contribute to their language and communication impairments.     

The status of girls’ education in Education for All Fast Track Initiative partner countries

This viewpoint examines girls’ performance in primary education in the countries that joined the Education for All Fast Track Initiative between 2002 and 2008. At the time they joined the initiative, a first group of countries (high performers) had already achieved high and equal enrollment of girls and boys. Significant progress is evident in a second group of countries (good performers) after joining the initiative. In contrast, a third group of countries (weak performers) continue to struggle to achieve any increase in girls’ enrollment. The article summarizes the various interventions that countries have adopted to encourage girls to attend school and then highlights the importance of developing strategic plans based on extensive collaboration between development partners and government. The viewpoint concludes by describing the three challenges that remain: increasing learning, reducing the number of out-of-school girls, and improving girls’ performance in fragile and post-conflict countries.
