ALSPAC – Age 8.5 – TEA-Ch Attentional Control (Opposite Worlds)

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 Attentional Control (Opposite Worlds) measure 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; oral answers
Procedure:A form of Stroop task. The child was shown a trail made up of the numbers 1 and 2 (with 24 numbers in total). The tester pointed to each number, one after the other, and the child delivered responses based on two conditions. In the 'same world' (control) condition, they read the numbers out as they were, as quickly as possible. In the 'opposite world' condition, the child had to say the opposite number to the one that was pointed to. A demonstration of each condition and a practice attempt at were administered first. There were four test trials: a same world trial, followed by two opposite world trials and finishing with another same world trial.

Scoring:Mean times for both same world and opposite world trials were calculated. 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 = approx. 100).
