Two‐year‐olds’ understanding of self‐symbols

This study investigated 48 2.5‐year‐olds’ ability to map from their own body to a two‐dimensional self‐representation and also examined relations between parents’ talk about body representations and their children's understanding of self‐symbols. Children participated in two dual‐representation tasks in which they were asked to match body parts between a symbol and its referent. In one task, they used a self‐symbol and in the other they used a symbol for a doll. Participants were also read a book about body parts by a parent. As a group, children found the self‐symbol task more difficult than the doll‐task; however, those whose parents explicitly pointed out the relation between their children's bodies and the symbols in the book performed better on the self‐symbol task. The findings demonstrate that 2‐year‐old children have difficulty comprehending a self‐symbol, even when it is two‐dimensional and approximately the same size as them, and suggest that parents’ talk about self‐symbols may facilitate their understanding.     

Early humour production

The current studies explored early humour as a complex socio‐cognitive phenomenon by examining 2‐ and 3‐year‐olds’ humour production with their parents. We examined whether children produced novel humour, whether they cued their humour, and the types of humour produced. Forty‐seven parents were interviewed, and videotaped joking with their children. Other parents (N= 113) completed a survey. Parents reported children copy jokes during the first year of life, and produce novel jokes from 2 years. In play sessions, 3‐year‐olds produced mostly novel humorous acts; 2‐year‐olds produced novel and copied humorous acts equally frequently. Parents reported children smile, laugh, and look for a reaction when joking. In play sessions, 2‐ and 3‐year‐olds produced these behaviours more when producing humorous versus non‐humorous acts. In both parent reports and play sessions, they produced novel object‐based (e.g., underwear on head) and conceptual humour (e.g., ‘pig says moo’) and used wrong labels humorously (e.g., calling a cat a dog). Thus, parent report and child behaviour both confirm that young children produce novel humorous acts, and share their humour by smiling, laughing, and looking for a reaction.
