Truth over falsehood
The English poet John Milton portrayed truth as a powerful warrior capable of defeating falsehood in open combat. The spread of false information online suggests otherwise. Here, we test the persuasive power and transmission potential of true versus false messages in a controlled experimental setting, free from the effects of social media algorithms and bot amplification. Across four experiments (combined N = 4,607), we tested how perceived verac…
A Cross-Sectional Test of Sign Creation by Children in the Gesture and Vocal Modalities
Naturalistic studies show that children can create language-like communication systems in the absence of conventional language. However, experimental evidence is mixed. We address this discrepancy using an experimental paradigm that simulates naturalistic sign creation. Specifically, we tested if a sample of 6- to 12-year-old children (52 girls and 56 boys drawn from an urban, predominantly white population in Western Australia) can comprehend an…
Innovation and enculturation in child communication
Applying the cultural ratchet to a social artefact
Material artefacts evolve by cumulative cultural evolution (CCE), the accumulation of adaptive modifications over time. We present a large-scale experiment investigating the CCE of a social artefact in transmission chains, each containing 8 adult human participants (N = 408). The social artefact is what Wittgenstein calls a ‘language game’, the subset of language used to perform a particular activity; in the present study the language game is to …
