We found that the number of blocks children tidied up was significantly positively correlated with the containers they used to tidy up, both across conditions and within the collaborative condition separately (across conditions: rho = .55, p <.01, N = 35; collaborative condition: rho = .58, p <.05, N = 18; for the individual condition it was marginally significant: rho = .45, p = .07, N = 17).
