“…Key environmental variables influencing behavior in early childhood include values [ 89 ], family stress and influence [ 60 , 77 , 90 ], parental styles, parenting patterns, expectations or biases of parents [ 77 , 91 ], quality of early stimulation [ 78 , 92 ], peer acceptance, teaching-learning strategies [ 7 , 30 , 93 , 94 ] and SES [ 58 , 59 , 88 ]. Cross-cultural studies emphasize these environmental variables as contributors, to varying extents, to the variability in early childhood executive performance, while acknowledging the potential impact of methodological weaknesses in data collection, as previously suggested [ 5 , 7 , 32 , 50 , 75 , 77 , 78 ]. To enhance the East vs West model, some authors propose conducting intra-country cross-cultural studies, particularly when aiming to identify culture-specific effects on population performance in a given domain [ 51 , 52 ].…”
