- ItemCommonality and variation in mental representations of music revealed by a cross-cultural comparison of rhythm priors in 15 countries(2021) Jacoby, Nori; Polak, Rainer; Grahn, Jessica Adrienne; Cameron, Daniel J.; Lee, Kyung Myun; Godoy, Ricardo; Undurraga Fourcade, Eduardo Andrés; Huanca, Tomas; Thalwitzer, Timon; Doumbia, Noumouké; Goldberg, Daniel; Margulis, Elizabeth; Wong, Patrick; Jure, Luis; Rocamora, Martín; Fujii, Shinya; Savage, Patrick E.; Ajimi, Jun; Konno, Rei; Oishi, Sho; Jakubowski, Kelly; Holzapfel, André; Mungan, Esra; Kaya, Ece; Rao, Preeti; Ananthanarayana, Rohit Mattur; Alladi, Suvarna; Tarr, Bronwyn; Anglada-Tort, Manuel; Harrison, Peter M. C.; McPherson, Malinda J.; Dolan, Sophie; Durango, Alex; Mcdermott, JoshMusic is present in every known society, yet varies from place to place. What, if anything, is universal to music cognition? We measured a signature of mental representations of rhythm in 39 participant groups in 15 countries, spanning urban societies and indigenous populations. Listeners reproduced random ‘‘seed’’ rhythms; their reproductions were fed back as the stimulus (as in the game of “telephone”), such that their biases (the prior) could be estimated from the distribution of reproductions. Every tested group showed a sparse prior with peaks at integer ratio rhythms. However, the importance of different integer ratios varied across groups, often reflecting local musical practices. Our results suggest a common feature of music cognition – discrete rhythm “categories” at small integer ratios. These discrete representations likely stabilize musical systems in the face of cultural transmission, but interact with culture-specific traditions to yield diversity evident when mental representations are probed across many cultures.
- ItemThe effect of gender targeting of food transfers on child nutritional status: experimental evidence from the Bolivian amazon(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2021) Bauchet, Jonathan; Undurraga, Eduardo; Zycherman, Ariela; Behrman, Jere; Leonard, William; Godoy, RicardoSome research suggests women are more likely to allocate additional resources to their children than are men. This perception has influenced policies such as in-kind food transfer programmes and cash transfer programmes, which often target women recipients. We assess whether targeting in-kind rice transfers to female versus male adult household members has a differential impact on children's short-run nutritional status. We estimate the impacts of transfers of edible rice and rice seeds, randomly allocated to female or male adults, on three anthropometric indicators: BMI-for-age, arm-muscle area, and triceps skinfold thickness. The trial includes 481 children aged 3-11 years in a horticultural-foraging society of native Amazonians in Bolivia. On average, the gender of the transfer recipient does not influence child anthropometric dimensions, possibly due to norms of cooperation and sharing within and between households. We find limited evidence of heterogeneity in impacts. Transfers to women help children who were growth stunted at baseline to partially catch-up to their better-nourished age-sex peers and help boys (but not girls) and children in higher-income households increase their BMI-for-age. The results of this research point to the importance of considering cultural context in determining if allocating food transfers according to gender are most effective.
