My thesis title is « ages and cinema : the cinematographic culture of young spectators ». This work deals with the seventh art socialization among youth and focus on the determinations of age – known as one of the most important sociological variable to understand societies – to select, taste and appreciate feature movies and series.In order to understand better its action, we decompose age between four different scales in the first part : individual age, socio-collective age, historical age and age of the objets surround us. This categories aren’t closed on themselves : they are combined by the actors to analyse and interprete arts and situations. Each temporality fragment known or imagined on each scale, lived or remembered by the actor can be mobilised as an appreciation’s tool. Theorising each age is a long work which necessits a better comprehension of individuality, memory, social interrelations, time, histories and body growth. We demonstrate that everybody embodies and crosses different fragments of different scales in everyday life to understand himself, the world surrounding and ultimately, the feature films content. Ways to understand, judge and appreciate art are a good field for studying temporal relations because arts objects are relatively preserved in time and tell about societies of the past. Each situation, person, object is structured by different kind of virtual or lived temporalities. When they are crossed according to the actor’s knowledge and his society position, they bring to different ways of art’s pleasure.The second part of my thesis shapes the first theorical one. It analyses the youth cinematographic culture. Thirty-four young spectators contributed to my sociological survey. They were aged from eight to fourteen years old. I studied the present socio-political structures in France and Europe leading to different forms of cinematographic socialisation. This part copes with the first feature movies rememberances – which are almost always composed by animation movies passed on by the parents – and their role in present art appreciation. At the age of the participants, the cinematography faces a global censure agreement : violent features are banished. Nevertheless, growing means to socialized with, that’s why two chapters of my thesis are consacred to the reception of more violent types of show at this ages, like the horrific gender for example which is often enjoyed by the youth. I try to understand how young people assimilate, step by step, the dark side of the world, the one which was previously hidded for their own safety. However, it is now a requirement of growth to mix with this forbidden shows. Peer reinforcement and autonomy help this initiation. They also bring to new cinematographic cultures as much as new social considerations. All this studies help us to understand how children and teenagers develop series and feature films’ taste by sharing it with friends or parents, depending on the content. This tell us about the developpment of quality classifications based on aesthetic, tales, relations, peers conversations, art memory, emotions and feelings. Finally, cinematographic culture appears to be a large social and aesthetical laboratory for the youth.This thesis is based on a qualitative survey. More specifically, I used a bottom-up method (Becker : 1988). The theories and the demonstrations are no less than the result of five years of several investigations’ technics on the field study. I began with individual consultations in France, Luxembourg and Belgium, then made collective groups in associations and schools. I created different questionnaires for the parents and the teenagers in aim to observe connections between their cinematographic cultures. This thesis claims interdisciplinarity.
