ALSPAC - Age 4 months - Habituation Task

The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) at 4 months’ age (Children in Focus Clinic) using the Habituation Task.

Details on this measure and the data collected from the CMs are outlined in the table below.

Years of data collection:	1992-1993
Domain:	Non-verbal; Habituation
Measures:	Correlates with later general ability
CHC:	None

Administration method:	Trained interviewer; clinical setting; physical task (eye-tracking)
Procedure:	Habituation refers to the extent to which attention directed towards a stimulus lessens over time. Research in this area works on the assumption that the amount of time an infant spends looking at a non-threatening stimulus before losing attention reflects speed of information processing. In other words, a child that ‘habituates’ to (i.e. loses interest in) a stimulus quickly is thought to be more efficient at processing information, compared with a child that takes a long time to lose interest in a stimulus. Habituation has been shown to correlate with later general ability (McCall & Carriger, 1993). During the task, the infant sat on the lap of the researcher, 18″ away from a computer screen that projected a picture of four diamonds. The eye movements of the infants were tracked, and ‘habituation’ was reached when two successive ’bouts’ of looking at the stimulus were shorter than the two previous ’bouts’. The infant was then presented with the same image alongside a new image, until s/he spent a total of 40 seconds looking at both (novelty preference).
