Comparisons of the BASIC-Memory and Learning Test and the WISC-IV Under Developmental Aspects
This study compares results of a new children memory and learning test, the BASIC-MLT and the latest Wechsler Intelligence Scale for Children-Fourth edition (WISC-IV) in a nonclinical German sample (N = 103). All participants were assessed with both instruments (order balanced). Pearson correlations were computed between subtest, scale and IQ scores from the intelligence scales and the scores from the BASIC-MLT separate for three defined age groups (Group 1: 6 to < 10 years, Group 2: 10 to < 13 years, Group 3: 13 to 16 years). Moderate to high correlations were found between Full Scale IQ (FSIQ) and BASIC-MLT’s memory quotient (MQ). Referring to Siegler’s (1998 , 2004 ) memory theories the relations of reasoning (Matrix Reasoning), semantic knowledge (Vocabulary), working memory (Letter-Number Sequencing) and processing speed (Symbol Search) were focused for further investigation. Significant correlations can be found for Matrix Reasoning and MQ in Group 1 only. For Vocabulary significant correlations can be found in Group 2 (p < .05) and Group 3 (p < .01). Letter-Number Sequencing has significant correlations with MQ in all age groups and Symbol Search in none. Comparisons of t-mean deviations in scales and subtests showed no significant differences in Group 1 and only few significant differences for Group 2 and Group 3. Results of children above 10 years of age are influenced by school type.
