Making sense of conflicting information: A touchscreen paradigm to measure young children's selective trust

Abstract

Abstract Much recent research has shown that children from age 4 onwards reveal a robust preference for reliable over unreliable informants when choosing whom to trust and learn from. Findings concerning selective model choice in children younger than 4 years have mostly been mixed. The present study developed a new touchscreen‐based paradigm with reduced task demands in order to test 2‐ and 3‐year‐old children ( N = 48). Results showed that 3‐year‐olds selectively endorsed information from a previously reliable rather than a previously unreliable informant when searching for objects whereas 2‐year‐olds just followed the first hint even if provided by an unreliable informant. Whether the lack of selective model choice in 2‐year‐olds reflects competence or performance deficits remains to be clarified. But the present results do suggest that 3‐years‐olds have the basic competence to selectively choose reliable over unreliable informants that may have been masked in some previous studies by task demands. Highlights The paper develops a novel touchscreen‐based search paradigm to test young children's selective trust with reduced task demands. Three‐year‐olds chose selectively between conflicting hints, whereas 2‐year‐olds followed the first hint even if provided by an unreliable informant.
