Young children fail to generate an additive ratchet effect in an open-ended construction task

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)本数据集以电子表格形式存储，包含2016年于英国与德国对101名年龄介于4.5至6岁之间的儿童开展测试所得的数据。所有儿童被分配至两种实验条件之一：基线条件（baseline）与传递链条件（transmission chain）。 数据集涵盖以下维度信息： - 月龄 - 性别 - 族裔 - 实验条件（基线条件、传递链条件） - （若适用）传递链编号 - （若适用）传递链内的位置/世代（取值范围为1至10） 受试儿童需使用100克橡皮泥与30根塑料棒搭建尽可能高的结构，该任务改编自Caldwell与Millen于2008年提出的意面塔任务（spaghetti tower task）。搭建时长限定为10分钟。 核心因变量包括： - 最终塔高：即测试结束时仍保持直立的塔的高度 - 塔的形状：采用Reindl、Apperly、Beck及Tennie即刊论文中的分类体系进行标注 本数据集同时包含以下补充信息： - 最终搭建的塔是否为高度最高的塔（是/否） - 高度最高的塔的实际高度 - 高度最高的塔的形状 - 实际测试时长（最长不超过10分钟）
