MICROGENETIC PATTERNS OF ADAPTATION ON THE STROOP TASK BY PATIENTS WITH BRONCHIAL ASTHMA AND DUODENAL PEPTIC ULCER

Abstract

Microgenetic patterns of adaptation on the Stroop task were assessed by means of the Serial Color-Word Test given 21 patients with bronchial asthma and 20 with duodenal peptic ulcer, who were compared with 41 normal controls matched for sex, age, and education. Two measures were calculated on each of the five trials of the test, one of linear change and one of nonlinear change in reading times. As predicted, patients presented more frequently patterns characterized by high nonlinear change and less frequently stabilized patterns (low linear and nonlinear change of reading speed). Linear and nonlinear change were then calculated on the five linear change scores and the five nonlinear change scores; again patients presented more frequently patterns characterized by high nonlinear change on both the linear change scores and nonlinear change scores and less frequently stabilized patterns. These findings indicate strong similarities between the adaptation patterns of patients with ulcer and asthma and the microgenetic patterns previously known to characterize neurotic and psychotic patients. Furthermore, scores on the Serial Color-Word Test also differentiated between ulcer and asthma groups.
