Are we really measuring what matters? The hidden challenges of studying children across cultures

Cross-cultural research in the social sciences is expanding rapidly, helping us understand how different cultures shape human behaviour. But here’s the big question: Are the tools we use actually measuring what we think they are in diverse populations? This issue of construct validity—ensuring research instruments truly capture what they are meant to—becomes even more complicated when studying children in diverse cultural settings. Our recent paper, Construct Validity in Cross-Cultural, Developmental Research: Challenges and Strategies for Improvement, reveals why this matters and how researchers can (try to, at least!) get it right

“Why We Love Suffixes: The Fascinating Cognitive Bias Shaping Language”

Verbal language, one of the hallmarks of human beings, enables us to express intricate thoughts, transmit cultural knowledge, and connect through generations. It is also one of the most studied domains in disciplines ranging from social sciences to neuroscience. Within this broad realm, the suffixing bias has turned out to be a particularly compelling phenomenon that continues to fascinate researchers as they attempted to provide an answer to the following question: Why do most world's languages use suffixes more than prefixes to convey grammatical meanings like tense or number? And what is this related to? Our general cognition? Is it language-specific? Or even an accidental distribution caused by some random factors that are not related to language cognition per se?
