This paper presents the results of a Rorschach assessment of a group of children with severe asthma (n = 21) compared to a control group (n = 21) of normal school children, matched for age and intellectual abilities. The design allows comparable data on total responses, movement, forms, color and other determinants. The mode of perception differs significantly between the groups. These differences will be discussed according to old hypotheses of personality traits as causative factors in the etiology of asthma.
