|---|---|---|---|---|---|
Domain | Sub-test | Outcome Measures | Domain | Sub-test | Outcome Measures |
Processing Speed | Simple Reaction Time Test (a plus sign of the screen prompts the child to press a key on the keyboard fast) | Mean RT & Median RT | - | - | Â |
Visuo-motor Coordination | Visuo-motor test (involves connection of elements/number in a given sequence) | TT & Total Errors | Â | Â | Â |
Sustained Attention | Continuous Performance Test (respondent presses any key every time the required stimulus appears) | Hits/CA, EO, EC, Mean RT & Median RT | Visual Sustained and Selective Attention Auditory Sustained and Selective Attention | People Search (A stimulus sheet comprising complete and incomplete stick figures is presented. The subject is required to cross out only complete figures, as quickly as possible) Digit span as we could not find the tape. The child is instructed to repeat a series of numbers (with increasing numbers of digits) forward. Each correct response is worth one point; with a maximum of 14 points for each sub-score series | TT, RT, Errors of Omission (EO) and Errors of Commission (EC) TT and Highest Score |
Memory | Verbal memory test (child listens to some words then repeats the ones remembered) Verbal memory delayed recall test (the series of words said are repeated after 20 min) Verbal Memory Essay of Recognition test (words are read out loud and respondents identifies those that were in the previous list) Visual memory (series of images are presented after which respondents verbalizes those remembered) Visual Memory delayed Essay (the images remembered are said out loud after 20 min) Visual Memory Essay of Recognition (respondent identifies if images presented were in previous list) | Hits/CA, P & I Hits/CA, P & I Hits/CA & Errors Hits/CA, EC & EO Hits/CA, EC & EO Hits/CA, EC & EO | Memory | Working Memory: Verbal List Learning – VLL (Two lists of 15 items are read out to the child as a shopping list. The first is presented five times and the second only once) Subtests within include: - Verbal Memory Test Free Recall Trial Test Short Delay Free Recall Trial Short Delay Cued Recall Trial Long Delay Free Recall Trial Long Delay Cued Recall Trial Long Delay Recognition Trial | Intrusions (I), Perseverations (P), CA and TT |
Language | Verbal Comprehension Images Test (respondent matches images to given conditions) Verbal Comprehension Figures (respondent matches geographic shapes to given conditions) Phonetic Fluency (a letter is presented and respondents verbalizes all words that start with the letter given.) | Hits/CA & Errors Hits/CA & Errors Hits/CA, I & P | - | - | Â |
Executive Functioning | Working Memory (a list of color and numbers are said and respondent repeats the numbers then the colors) Abstract Reasoning (respondent completes a logical series by selecting the right element) Semantic Fluency (a category is given and respondents says the elements known in that category) Inhibition: Go/NO-GO (respondents identifies distinguishing factor between two elements and later identify the distinguishing element) Flexibility: Spatial Stroop (respondent matches arrow directions to arrow labels) (Two components of spatial stroop—attention shifting task measures flexibility while proper spatial stroop task measures inhibition) Flexibility: Alternate Visuo-motor (is flexibility measure that involves two distinct series in which the respondent should connect alternatively) Planning: Attraction Park (respondent chooses a number of attractions according to money in hand with each attraction chosen expiring after a given period) | Hits/CA Hits/CA Hits/CA, I & P EC, Hits/CA & Mean RT Median RT, EC, EO TT & Total Errors Planning Time, TT, Rule 1, Rule 2, fairground amusements & different fairground amusements/CA | Executive Functioning | Self-Ordered Pointing Test—SOPT (Selection of pictures displayed in varying positions on separate sheets in sets of 6, 8, 10, and 12. As each page is turned the subject is required to identify all members of the set, but to point to each item of the set only once. Touching a picture more than once is considered an error) Raven progressive matrices: Reasoning: Colored Progressive Matrices – CPM (Three sets with 12 matrices made of abstract patterns. The subject is asked to complete the matrix by placing one of a choice of four patterns in the empty space) Attention and attention shift: Contingency Naming Test – CNT (The child is taught a series of rules to name nine drawings displayed in a single series. Each drawing consists of a large outer colored shape and a smaller inner colored shape. Each drawing is named according to the shape or color of one of its two shapes. The rules taught for selecting the name of the item become more complex over four trials) Planning: Tower Test/ Tower of London (Three colored wooden balls are moved between three pegs to match a goal position. Time and number of moves required are recorded) | Time Taken(TT), Reaction Time(RT) and Correct Answers (CA) |
