The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 8.5 sweep (Focus@8) using the Sky Search measure of selective attention and motor control from the Test of Everyday Attention for Children (TEA-Ch).
Details on this measure and the data collected from the CMs are outlined in the table below.
|CHC:||Gs (Processing Speed)|
|Gps (Psychomotor Speed)|
|Gv (Visual Processing)|
|Gsm (Short-Term Memory)|
|Administration method:||Trained interviewer; clinical setting; pen and paper|
|Procedure:||The child was presented with an array of non-identical and identical spaceships, and was tasked with circling pairs of identical spaceships as quickly as possible, whilst trying to avoid any errors. The interviewer provided a demonstration, and the child worked through a practice sheet before commencing the test. After the practice sheet, the child was presented with a larger sheet and asked to do the same (20 identical pairs). The above task was then repeated, without the non-identical pairs of ships. The aim was to identify how quickly the child could complete the task, in order to control for motor performance.|

|Scoring:||Three summary scores are provided:|
|i. unadjusted score: time taken (in seconds) for the search task divided by the number of spaceship pairs correctly circled|
|ii. motor score: time in seconds for the motor task divided by number of correct pairs|
|iii. The adjusted score is calculated by subtracting the motor score from the unadjusted score, thus controlling for motor speed|
|iv. A normative score is also available, however the ALSPAC codebook recommends this is used with caution, as the original sample used to create the normative scores was small (N = ~100)|
|Item-level variable(s):||f8at003 - f8at061|
|Total score/derived variable(s):||f8at061, f8at062, f8at065|
|Descriptives:||Unadjusted score||Motor score||Adjusted score|
|N = 7,249||N = 7,219||N = 7,184|
|Range = 1.94 - 48.33||Range = 0.35 - 7||Range = -4.05 - 46.58|
|Mean = 6.58||Mean = 1.37||Mean = 5.20|
|SD = 2.07||SD = 0.46||SD = 1.92|
