From: Children’s limited tooling ability in a novel concurrent tool use task supports the innovation gap
The innovation gap in two tool reshaping tasks. Each colour represents a study, each point represents an experimental condition, and sample size for each experimental condition is reflected in point size. The black line represents predicted values, weighted by sample size. The “hook task” represents only conditions in which a wire had to be reshaped; results from conditions in which children were shown a premade hook tool template before attempting the task were not included (as any subsequent tool made was not strictly innovated). More information on the experiments and data included in the graphs can be found in the open access repository.
