Spanish university students spend hours online studying, socialising and having fun. But how important are the skills to evaluate sources and behave properly online? Researchers surveyed 415 young adults aged 18 to 36, asking when they got their first smartphone. The findings reveal that those who started using a phone before age 13 rely more on two abilities: netiquette, i.e., respecting online communication rules, and the capacity to verify information reliability. Both skills better predict deep learning than for those who got a phone later. In both groups, critical thinking remains the key factor for deeper understanding. The study suggests universities should offer digital literacy courses, teaching source verification and respectful communication. Thus, regardless of the age of first smartphone use, students can develop a more critical mind and stronger learning capacity. Limitations include self‑reports, convenience sampling and a cross‑sectional design, but the results point to new teaching strategies.
The term "deep learning" in education should not be confused with neural network technology. Here it refers to profound understanding, linking new information to prior knowledge and developing analysis and synthesis skills. Netiquette, defined as the set of online behavior norms, influences interaction quality and the ability to collaborate in virtual environments. Cognitive psychology studies show that critical source evaluation activates the prefrontal cortex, enhancing long‑term memory. Early exposure to mobile devices may foster multitasking abilities but also increase reliance on superficial stimuli. The research employed multiple linear regression to isolate each variable's effect, controlling for age, gender and study level. Beta coefficients reveal that netiquette (β=0.32) and reliability verification (β=0.28) have a stronger impact on deep learning in participants with smartphones before age 13, compared to the older group (β=0.15 and β=0.12). These findings suggest digital literacy programs should include practical fact‑checking exercises and online communication simulations to strengthen neural networks involved in meaningful learning.
