Sažetak The aim of this study was to test the basic assumption of the paulhus model which splits socially desirable responding into 'unconscious' self-deception and 'conscious' impression management. The study was conducted in three motivational conditions: anonymous/honest (N=370), selection (N=602) and 'fake good' on independent samples of participants. In all three situations the same instruments were used: IPIP-100 for measurement of five broad personality dimensions and social desirability scales measuring self-deception and impression management.The results have shown that impression management and self-deception increased with the increase of motivation for favorable self presentation. Regarding personality, the two dimensions showed different patterns of relationship with five dimensions. The results reject the original Paulhus model, confirming its new conceptualizations.
