“…The papers vary across different domains; theory of mind and inhibitory control (Flynn, 2007), analogical reasoning (Cheshire et al, 2007;Tunteler & Resing, 2007), understanding balance (Philips & Tolmie, 2007), counting (Cheshire et al, 2007;Chetland & Fluck, 2007) and language development (van Dijk & van Geert, 2007). The studies vary across time scales, from trial-by-trial change (Chetland & Fluck, 2007), to developmental trajectories over weeks (Cheshire et al, 2007) or months (Flynn, 2007;van Dijk & van Geert, 2007). This can be measured at the levels of individuals (Chetland & Fluck, 2007;Flynn, 2007;van Dijk & van Geert, 2007), dyadic relationships (Philips & Tolmie, 2007) or in terms of group changes (Cheshire et al, 2007;Philips & Tolmie, 2007).…”
