The discontinue rule was set at the lowest number of consecutive scores of 0 that resulted in a rank-order correlation of. For example, the Similarities discontinue rule was five consecutive scores of 0 for standardization and was reduced to three consecutive scores of 0 for the final version of the scale.
A number of other discrepancy analyses can be conducted between the index scores e. The process-level discrepancy comparisons reflect the differences between scores for a subtest and the corresponding process score i. These process-level discrepancy comparisons may be of particular clinical interest. For example, additional information on the contribution of speed to an examinee's Block Design performance may be obtained from comparing the BD and BDN scaled scores.
Prior to interpretation, the practitioner should know whether such a difference is statistically significant and how frequently it occurs in the normative sample. We did extensive market research with customers, using unaided questions, to determine the need for new clinical studies. Pearson may provide support for such studies by providing test materials and matched control groups for comparison. Why is reliability lower for the intellectually gifted and the intellectually disabled formerly referred to as mental retardation special group samples than for the normative sample?
It is a consistent finding that the restriction in the range of scores obtained by these groups frequently results in lower reliabilities. Generally, the answer is no. However, ongoing research may identify certain characteristics of cognitive functioning for specific clinical disorders. While specific profiles are not diagnostic of particular disorders, working memory and processing speed are implicated in a variety of psychoeducational and neuropsychological disorders. Consistent with current research, studies reported in the WAIS—IV Technical and Interpretive Manual suggest that examinees with various neuropsychological and learning issues tend to perform lower on working memory and processing speed tasks.
Why is this? Gifted examinees tend to score lower on Processing Speed subtests relative to subtests from other scales, perhaps due to a problem solving approach that stresses accuracy over speed. To meet my state's cognitive requirements for a diagnosis of intellectual disability formerly referred to as mental retardation , the VIQ, PIQ, and FSIQ scores must all be below 70 points. States and other regulatory bodies may update their terminology in the near future.
I work in an area where many different languages are spoken. What do I do if an examinee has recently immigrated to the United States and needs to be assessed in a language other than English? For examinees whose families have recently immigrated, these are the most current, valid tests available in their first language.
Use of these adaptations requires an examiner or experienced professional who is fluent in the examinee's language. Standardization projects are underway for English language versions in Australia and England; a French version is also under development for use in French-speaking Canada.
These particular subtests were omitted from the test protocol for ages 70—90 for various reasons. These subtests were not administered to ages 70—90 due to concerns with fatigue in older adults. Standardization editions include more items, involve using longer discontinue rules, and require additional recording procedures relative to final editions of tests. These factors increase testing time.
In standardization, examinees typically are administered both the main test being standardized e. The introduction of Digit Span Sequencing decreased the unique information that Letter—Number Sequencing contributes to the battery.
Figure Weights and Cancellation were new subtests, with unproven utility for older adults. All of these subtests were likely to be selected as supplemental subtests. Ultimately, the decision was made to omit these subtests for these ages. Block Design was chosen as the first subtest because it is an engaging task that gives the examiner more opportunity to establish rapport. When testing examinees with motor impairment, examiners may decide to begin with a different subtest in the interest of rapport.
If you wanted to reduce the effects of speeded performance, why not eliminate time bonus points from Block Design altogether? In general, higher ability examinees tend to perform the task faster.
Without time bonus points, Block Design does not provide fine discrimination at higher ability levels. Why do Visual Puzzles and Figure Weights have strict time limits, and Matrix Reasoning only has a 30 second guideline? Similar to Block Design, higher ability examinees tend to perform Visual Puzzles and Figure Weights items more quickly.
Given enough time, low ability examinees can eventually respond to items correctly. This is not the case with Matrix Reasoning. The 30 second guideline was established because completion time data indicated that the vast majority of examinees who will respond correctly do so within 30 seconds, but giving additional time to low ability examinees did not result in correct scores.
A strict time limit is therefore unnecessary: Grant additional time if the examinee has established a pattern of providing delayed but correct responses as the item difficulty increases. To avoid interference effects between Digit Span and Letter—Number Sequencing, these subtests were widely separated in the order of administration. In the Letter—Number Sequencing subtest, the examinee is instructed to repeat the numbers in ascending order first, and then the letters in alphabetical order.
For Items 3—10, why is credit awarded if the examinee repeats the letters first in order and then the numbers in order? There is a distinction between reordering and sequencing: Reordering involves placing the numbers as a group prior to the letters as a group, and sequencing involves placing the numbers in numerical order and the letters in alphabetical order—regardless of which grouping comes first. The reason for instructing examinees to reorder the numbers before the letters is to provide a structured way of approaching the task, which is especially helpful for examinees that are anxious or have difficulty structuring their own work.
Using Sample Item A, the examinee is taught to reorder the number before the letter for the two-character trials. If the examinee does not reorder correctly as instructed, no credit is awarded for a given trial on Items 1—2. Sample Item B is used to teach the examinee to sequence the numbers and letters, while maintaining the previous reordering instruction. For Items 3—10, credit is awarded for sequencing alone: Regardless of how the examinee reorders the numbers and letters, he or she is using working memory to sequence the numbers and sequence the letters.
Although the incorrect reordering approach has always been infrequently observed, the graduated teaching strategy introduced for WAIS—IV has reduced the frequency of incorrect reordering even further.
In addition, prior data analysis results have indicated that these items are equally difficult when either numbers or letters are given first. What should I do if an examinee writes too faintly to be seen through the Cancellation scoring template? You don't need the scoring template to score the subtest.
If necessary, remove the template and simply count each correct shape with a mark through it and each incorrect shape with a mark through it.
