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.

| 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 | ||
