“…Secondly, these individual differences seem to be rather stable or even increasing over time in MCK (e.g., Alexander et al 1995;Hannah and Shore 1995;Schwanenflugel et al 1997) and rather stable in RC (e.g., De Jong and Van der Leij 2002; Lerkkanen et al 2004;). However, some recent studies, looking more carefully at the individual transitions across time, have revealed different individual developmental trends, both progressive and regressive, thus changing the relative position of a number of children (in metacognition, see e.g., Annevirta and Vauras 2001; in RC, see e.g., Aunola et al 2002). Therefore, we cannot expect to find straightforward cumulative developmental trends in either skill domain.…”
