Children perseverate to a human's actions but not to a robot's actions

Previous research has shown that young children commit perseverative errors from their observation of another person's actions. The present study examined how social observation would lead children to perseverative tendencies, using a robot. In Experiment 1, preschoolers watched either a human model or a robot sorting cards according to one dimension (e.g. shape), after which they were asked to sort according to a different dimension (e.g. colour). The results showed that children's behaviours in the task were significantly influenced by the human model's actions but not by the robot's actions. Experiment 2 excluded the possibility that children's behaviours were not affected by the robot's actions because they did not observe its actions. We concluded that children's perseverative errors from social observation resulted, in part, from their socio-cognitive ability.     

The effect of labour on ownership decisions in two cultures: Developmental evidence from Japan and the United Kingdom

Creative labour has an effect on children's and adults' ownership decisions in Western cultures. We investigated whether preschoolers and adults from an Eastern culture (Japan) would show a similar bias. In a first‐party task (Experiment 1), in which participants created their own objects, Japanese preschoolers but not adults assigned ownership to creators. When participants watched videos of third‐party conflicts between owners of materials and creators (Experiment 2), Japanese adults, but not preschoolers, transferred ownership to creators. In a British comparison group, both preschoolers and adults showed an effect of creative labour in the third‐party task. A bias to attribute ownership on the basis of creative labour is thus not specific to Western culture.
