ALSPAC – Age 8.5 – TEA-Ch Sky Search ShareThis

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.

Measures:Selective attention
Mental speed
Visual scanning
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
