The Open Anchoring Quest Dataset: Anchored Estimates from 96 Studies on Anchoring Effects
People’s estimates are biased toward previously considered numbers (anchoring). We have aggregated all available data from anchoring studies that included at least two anchors into one large dataset. Data were standardized to comprise one estimate per row, coded according to a wide range of variables, and are available for download and analyses online (https://metaanalyses.shinyapps.io/OpAQ/). Because the dataset includes both original and meta-data it allows for fine-grained analyses (e.g., correlations of estimates for different tasks) but also for meta-analyses (e.g., effect sizes for anchoring effects)
Socio-economic status and early childhood cognitive skills : is Latin America different?
This paper documents differences in cognitive development – as measured by a receptive vocabulary test – between children from households with high and low socioeconomic status (SES) in two different phases of childhood (before and after early school years) in four developing countries: Peru, Ethiopia, India and Vietnam. Intercontinental evidence on the timing, pattern, and persistence of these differences is provided. The non-parametric analysis suggests that differences found at the age of 5 persist into the early school years across all four countries, and the conditional analysis shows that the magnitude of within-country SES differences seem to diminish over time (with the exception of the India sample). However, both the magnitude of the gap and the degree of persistence vary. The main result is that Peru stands out, not only as the country with the largest cross-section difference between rich and poor (of around 1.30–1.40 standard deviations), but also as the country with the highest persistence in cognitive development, as shown by the value-added specification. Some channels behind these trends are discussed, but overall, the SES gradient persists even when controlling for a range of important mediators, such as preschool, early nutrition, and years of schooling. Past performance on the Peabody Picture Vocabulary Test (PPVT) is an important determinant of the SES gradient at the age of 8
Early childhood stimulation interventions in developing countries: A comprehensive literature review
Integrating a Parenting Intervention with Routine Primary Health Care: A Cluster Randomized Trial
A parenting intervention delivered at routine primary health visits improved child cognitive development and parenting knowledge
A remote parenting program and parent and staff perspectives: a randomized trial
OBJECTIVES: To assess impact and implementation of remote delivery of a parenting program following suspension of in-person visits during the coronavirus disease 2019 pandemic. METHODS: Impact of remote delivery of the Reach Up parenting program on parenting practices was evaluated by randomized trial in Jamaica. Mothers with children aged 5 to 24 months who met 1 of 7 at-risk criteria were enrolled at health centers. Participants were randomly assigned to intervention or control using random number tables generated by a statistician. Intervention comprised a manual for parents with illustrated play activities, phone calls, and short message service messages. The control group received usual care. Parent practices were measured using an adapted Family Care Indicators telephone-administered questionnaire by interviewers unaware of group assignment. Qualitative interviews were conducted with staff and parents in Jamaica and Brazil and staff in Ecuador to identify facilitators and barriers to remote delivery of Reach Up. RESULTS: Two hundred forty-seven participants were assessed at endline (control n = 130; intervention n = 117). Intervention increased parent activities that support child development, effect size 0.34 SD (95% confidence interval 0.03-0.53), and use of praise, odds 2 times higher with intervention. There were no benefits to interactive language or play materials. Qualitative results showed parents appreciated program continuation and felt motivated to help their child, and methods were acceptable to staff. Barriers included poor mobile phone access, difficulty contacting parents, and feedback limitations without in-person contact. CONCLUSIONS: Remote delivery methods have potential to contribute to scaling of parenting programs
Integrating a Parenting Intervention With Routine Primary Health Care: A Cluster Randomized Trial
Recognizing early childhood education as a human right in international law
There is incontrovertible evidence that early learning opportunities shape long-term development and health. Nevertheless, early childhood care and education (ECCE) is not expressly mentioned as part of the right to education in the Convention on the Rights of the Child, the International Covenant on Economic, Social and Cultural Rights, and the Convention on the Rights of Persons with Disabilities. This paper argues that the right to education can nevertheless be regarded as including ECCE. We examine the treaties, General Comments, and 264 Concluding Observations by relevant UN monitoring bodies, covering 152 countries from 2015 to 2020, to determine whether the right to ECCE is regarded as part of States’ obligations and the content of the duty. These demonstrate consistently that States must provide affordable, accessible, quality, inclusive ECCE, with adequate resources. We argue that monitoring committees should draw these obligations together in one General Comment, thereby improving States’ accountability and guiding the delivery of ECCE.</p
