The spreadsheet contains data from 101 children between 4.5 and 6 years tested in the UK and in Germany in 2016. Children were assigned to one of two conditions (baseline, transmission chain). The data contains information about: - age in months - sex - ethnicity - condition (baseline, transmission chain) - if applicable: number of chain - if applicable: position/generation within chain (ranging from 1 to 10) Children were asked to build something as tall as possible using 100 g of plasticine and 30 plastic sticks. (this is an adaptation of the "spaghetti tower task" (Caldwell & Millen, 2008). Building time was 10 min. The main dependent variables are: - final tower height (= height of the tower that was standing at the end of the testing session) - tower shape (using the classification system in Reindl, Apperly, Beck, & Tennie, in press) The spreadsheet also contains data on: - whether the "final tower" was also the tower with the maximum height (yes/no) - the height of the tower with the maximum height - the shape of the tower with the maximum height - actual testing duration (max 10 min)
