Özet

In the present study a test of digit span, classified also as a neuropsychological device, is revised with respect to its empirical, methodological and theoretical shortcomings or handicaps and is made suitable for utilization on adults also. The test is called the Visual Aural Digit Span Test Form B (GIST-B) and involves visual or aural presentation of digits which the subject responds to in oral or written form The standardization study was carried on 848 Ss. The 13-19 year old Ss ware from state and private junior and senior high schools (n= 372) and the 20-54 year old Ss from state and private institutions (n= 476). The research design of the standardization study involved age (2 levels), sex (2 levels) and education (3 levels). Test-retest reliability of the Total Score of GIST-B was found to he 0.84 and the construct validity obtained from the correlation of the test with the digit span subtests of WAIS was in the range of 0.67 - 0.84. The results substantiated the general finding about the STM capacity; the basic 7+2 rule. However the scores varied with age and education. The 2X2 Anova revealed a significant main effect of age and sex for the Total Score. The 2X2X2 Anova revealed a significant main effect of age and also education for the Total Score. The findings on Total Scores was parallel to those on the other 10 scores.
