highly significantP < 0.001
Notice that the correlation between these variables is highly significant: AOA Catalan and Catalan proficiency ( r = −0.4, P < 0.001, later exposition to Catalan, decreased proficiency in Catalan) and AOA Catalan and Language use ( r = 0.53, P < 0.002, delayed onset of Catalan exposition, greater use of Spanish).
