Note. RC = reading comprehension operationally defined by the total score of the CPET.
VS = vocabulary size operationally defined by the total score of the VLS.
AK = word association knowledge operationally defined by the total score of the DVK association items.
CK = collocation knowledge operationally defined by the total score of the DVK collocation items.
MK = morphological knowledge operationally defined by the total score on the MST, including two subtests: Syncat-real test and Relational test.
SYN = the total score of the Syncat-real test.
REL = the total score of the Relational test.
MO = motivation operationally defined by the total score of the LLOS.
SE = self-efficacy operationally defined by the total score of the MSLQ.
