In previous Investigations the existence of sex differences has been provedin an adult sample, in landscape (Macia, 1979a, 1979b; Bernaldez, 1989)as well as in the categorization that adults make of the environment (Maciaand Huici, 1986). We are carrying out, with permission from LE. Bunting, the translation andadaptation of the Children Environmental Response Questionnaire (CERI) toa Spanish population. The CERI, which may be considered as a downward re-view of -- Mckechnie's ERI (McKechnie, 1974), is based on the considera-tion that children have a set of stable and relatively enduring dispositionstoward the environment (Bunting and Cousings, 1983). These dispositions would be reflected in beliefs, attitudes and values. The questionnarle is corn-posed, In the original English version, by one hundred and eighty-five itemswhich evaluate nine scales: Pastoralism (PA): Enjoyment and conservationof the natural environment in an intellectual and aesthetic fashion; Urban-ism (UR): Attraction to the complexity and diversity of city living, itsphysical, social and cultural richness; Environmental Adaptation (EA):Professed belief in man's ability to dominate nature. Strong preference fortechnologically adapted environment; Stimulus Seeking (55): Interest inunusual, adventurous and varied events and envronmental settings; Envi-ronmental Trust (ET): Feelings of competence, securityand comfort in man-made and natural environments; Antiquarianim (AN): A positive emotionalresponsiveness to the historical past and a traditional orientation to envi-ronmental design; Need Privacy (NP): A need to control stimuli impiningfrom the surronding environment; Mechanical Orientation (MO): Attractionto mechanical processes and the application of manipulative skills; andCommuuunality (CO): A validity scale derived from responding In a statisti-cally model fashion.In the version that we are carrying out we have reduced these one hun-dered-and eighty-five items to eighty-seven, which evaluate the same orig-inal scales. These items were defined and reduced using several factor anal-ysis, verifying-that reliability and validity of the scales awere constant.The questionnarie has been applied to a sample of two hundered and fifty-four children in the age range of ten to fourteen years,of which one hunderedand sixty-four were boys and ninety were girls.The investigation that we present is a studyof the results obtained in the ap-plication of CERI for the sample described. Our goal is centered in studying-possible sex and age differences in the answers given to the questionnaire.
