This paper aims to deepen the understanding of the role of "local norms" in explaining ecological behavior within Ajzen's Theory of Planned Behavior. A longitudinal investigation (overall N = 222), focused on households waste recycling, tested the hypothesis that the effects of this type of norms on behavioral intentions varies as a function of the individual's spatial proximity to the social categories relevant to the social-physical context (in this study: housemates, neighbors, inhabitants of the district or quarter, and inhabitants of the city) in which the behavior takes place.

Background: Premature birth is often associated with neurodevelopmental difficulties throughout childhood. In
the first three years of life, the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III)
constitute one of the most used tools for assessing child development. Since Bayley-III original norms are based
on United States (US) population, it remains uncertain whether their use in other countries (e.g., European) is
appropriate.
