Edited sentence: Comparing North American Exner normative data with data from European and South American subjects showed marked differences in some features, some of which impact important variables, while others (such as the average number of responses) coincide.For instance, texture response is typically zero in European subjects (if interpreted as a need for closeness, in accordance with the system, European would seem to express it only when it reaches the level of a craving for closeness), and there are fewer "good form" responses, to the point where schizophrenia may be suspected if data were correlated to the North American norms.Form is also often the only determinant expressed by European subjects; while color is less frequent than in American subjects, color-form responses are comparatively frequent in opposition to form-color responses; since the latter tend to be interpreted as indicators of a defensive attitude in processing affect, this difference could stem from a higher value attributed to spontaneous expression of emotions.The differences in form quality are attributable to purely cultural aspects: different cultures will exhibit different "common" objects (French subjects often identify a chamaleon in card VIII, which is normally classed as an "unusual" response, as opposed to other animals like cats and dogs), and different languages will exhibit semantic differences in naming the same object (the figure of card IV is often called a troll by Scandinavians and an ogre by French people)
