Summary Individual differences in susceptibility to metacontrast may have their origin in differences in tke thresholds for identification target. When this threshold is controlled, some subjects appear to be more susceptible than others to metacontrast. When the target and the mask are simultaneous, the increase of the target threshold is accounted for by the reduction of figure-ground contrast resulting from luminance summation of the stimulus fields.Résumé Les différences individuelles existant dans le métacontraste peuvent avoir pour origine celles qui sont enregistrées dans les seuils d'identification du ST. Lorsque cette variabilité due aux seuils d'identification est neutralisée, on constate que certains sujets sont plus sensibles qu...
