Impostors are outwardly successful individuals who experience secret intens
e feelings of fraudulence in achievement situations. Elements of perfection
ism are evident in a tendency on the part of impostors to maintain high sta
ndards for personal evaluation while being critical of their inability to r
ealise these standards. This study utilised a 2 (impostor status: high, low
) x 2 (task type: high vs, low frequency of mistakes) between-subjects fact
orial design to investigate the connection between impostor fears and perfe
ctionistic concern over mistakes. Sixty undergraduate students completed ei
ther a high or low frequency of mistake Stroop Colour-Word task, following
which they completed items assessing perceptions of their performance, conc
ern over mistakes, perceptions of control and anxiety, the Positive and Neg
ative Affect Scale and the Russell Causal Dimension Scale. Links with perfe
ctionistic concern over mistakes and anxiety were strongly supported, with
impostors reporting less control, greater anxiety, more negative affect and
greater concern over mistakes than non-impostors irrespective of experimen
tal condition. The roles of anxiety and perfectionist cognitions in the mai
ntenance of impostor fears are discussed. (C) 2000 Elsevier Science Ltd. Al
