When the restrictions regarding which subtests could enter were relaxed, the best four-subtest solution included information, block design, comprehension, and similarities.
Why Princess Toadstool, Yoshi and Toad all were passed over for Question Mark block is beyond my comprehension.
Maternal IQ was assessed using the Information, Comprehension, Similarities, and Block Design subtests of the Wechsler Adult Intelligence Score (Wechsler 1968).
The full-scale intelligence quotient (IQ) provides a summary of overall cognitive ability and was obtained using a shortened version of the Wechsler Adult Intelligence Scale III (WAIS-III), which assesses vocabulary comprehension, visuoconstructive ability (block design), verbal reasoning (similarities) and nonverbal deductive reasoning (matrices).
The autism group resembled only one of the schizophrenia clusters, with both showing elevations on the WAIS-R Information and Block Design subtests and depressions on Comprehension and Digit Symbol.
Data from measures analogous to those in the WISC-III were examined (performance and verbal IQs, verbal information, digit symbol coding, block design, picture completion and verbal comprehension).
But reading comprehension may be a larger stumbling block.
The test, a version of an exam known as the Wechsler Preschool and Primary Scale of Intelligence, consists of two sections: verbal (which includes vocabulary and comprehension) and performance (picture concepts and block design, among other skills).
Verbal (information, similarities, arithmetic, vocabulary, comprehension) and performance (picture completion, coding, picture arrangement, block design, object assembly) subscales were administered, the subtests scaled and scores for total IQ derived.
Following up with basic yes-no questions about each sentence's content, they found that comprehension dropped by about 25% in trials that blocked rereading versus those that didn't, the researchers report online this month in Psychological Science.
Block Design, Similarities, Digit Span, Picture Concepts, Coding, Vocabulary, Letter-Number Sequence, Matrix Reasoning, Comprehension, and Symbol Search subtests were completed.
