Letter-Number Sequencing (secondary) – children are provided a series of numbers and letters and asked to provide them to the examiner in a predetermined order. The WMI is a measure of working memory ability. The PSI is derived from the Coding and Symbol Search subtests. The Processing Speed subtests are as follows:
The WAIS-5 introduces several new subtests, particularly in the working memory domain, with Digit Span Sequencing and Running Digits now being the core subtests that compose the Working Memory Index. Digit Span Forward, Digit Span Backward, and Letter-Number Sequencing may also be used to construct the Expanded Working Memory Index.
The Verbal Fluency Test measures letter fluency, category fluency, and category switching The Design Fluency Test measures one's initiation of problem-solving behavior, fluency in generating visual patterns, creativity in drawing new designs, simultaneous processing in drawing the designs while observing the rules and restrictions of the task ...
A digit-span task is used to measure working memory's number storage capacity. Participants see or hear a sequence of numerical digits and are tasked to recall the sequence correctly, with increasingly longer sequences being tested in each trial. The participant's span is the longest number of sequential digits that can accurately be remembered.
The Trail Making Test is a neuropsychological test of visual attention and task switching. It has two parts, in which the subject is instructed to connect a set of 25 dots as quickly as possible while maintaining accuracy. [ 1 ]
A verbal fluency test is a kind of psychological test in which a participant is asked to produce as many words as possible from a category in a given time (usually 60 seconds). This category can be semantic , including objects such as animals or fruits, or phonemic , including words beginning with a specified letter, such as p , for example. [ 1 ]
A popular example is King Tut's funeral mask which is adorned with turquoise, the Geological Institute of America reports. The stone spans from blue to green in color.
The missing letter effect is more likely to appear when reading words that are part of a normal sequence, than when words are embedded in a mixed-up sequence (e.g. readers asked to read backwards). [5] Despite the missing letter effect being a common phenomenon, there are different factors that have influence on the magnitude of this effect.
