Starting from a system bringing French individuals to express the affective links which they perceive between Europeans of various nationalities, we obtain a representation of Europe opposing the western to the eastern countries on an axis and the &ldquo;sunny&rdquo; to the &ldquo;cold&rdquo; countries on a second axis. The correspondence to geographic reality is quite close, the correlations between the subjective and the geographical axes being &gt; 0.67, and so, significant. Yet, the bias due to social categorisation (assimilation, contrast, discrimination) only appears for the East-West axis, whereas the situation on the North-South axis does not reveal a systematic distortion in the perception. So, it seems that belonging to the Western bloc is a part of the subjects&rsquo; identities since they treat this bloc as an endogroup, opposite to the exogroup constituted by the countries of the other bloc.</p> </r2r:ml><r2r:ml lang="fr"> <p class="resume" dir="ltr">Le but de cette recherche est de mettre au jour, gr&acirc;ce aux lois de la cat&eacute;gorisation sociale, les dimensions identitaires pertinentes dans le cadre de l&rsquo;Europe.&nbsp;A partir d&rsquo;un dispositif amenant des sujets fran&ccedil;ais &agrave; exprimer les liens affectifs qu&rsquo;ils per&ccedil;oivent entre Europ&eacute;ens de diff&eacute;rentes nationalit&eacute;s, on obtient par AFC une repr&eacute;sentation de l&rsquo;Europe opposant les pays occidentaux aux pays orientaux sur un premier axe et les pays ensoleill&eacute;s aux pays froids sur un deuxi&egrave;me axe. La conformit&eacute; &agrave; la r&eacute;alit&eacute; g&eacute;ographique est importante, les corr&eacute;lations entre les axes subjectifs et les axes g&eacute;ographiques &eacute;tant sup&eacute;rieures &agrave; 0,67 et &eacute;tant significatives. Cependant, les biais dus &agrave; la cat&eacute;gorisation sociale (assimilation, contraste, discrimination) n&rsquo;apparaissent que pour l&rsquo;axe Est-Ouest, la situation sur l&rsquo;axe Nord-Sud n&rsquo;entra&icirc;nant pas de d&eacute;formation syst&eacute;matique dans la perception. Il semble donc que l&rsquo;appartenance au bloc occidental est constitutive de l&rsquo;identit&eacute; des sujets puisqu&rsquo;ils traitent ce bloc comme un endogroupe auquel s&rsquo;oppose l&rsquo;exogroupe constitu&eacute; par les pays de l&rsquo;autre bloc.</p> </r2r:ml>
