The computerized version of the Concentration Endurance Test (test d2) and the problem of transfer equivalence
T. Merten

148 neurological patients with an age range from 16 to 69 years were given Brickenkamp’s Concentration Endurance Test on two consecutive days. The administration mode (conventional vs. computerized) and constancy vs. change of mode from first to second administration varied systematically. When the same test version was given twice, there was an increase in test performance. However, similar to a previous study (Merten, 1999a) with the Benton Visual Retention Test, specific transfer effects were observed when the mode of administration was changed. In particular, there was no increase in test scores when the conventional administration of the test was followed by the computerized version. However, both tests yielded substantial correlations with a number of other neuropsychological tests, such as Reitan’s Trails A and B, WAIS Block Design, Hooper Visual Organization Test, Raven’s Standard Progressive Matrices, etc. Patients indicated a clear preference for the computerized d2 test version.

Key words: computer-assisted testing, attention, equivalence, Concentration Endurance Test
