Peer reviewedButterworth, George – Child Development, 1976
To establish the spatial generality of perseverative errors in infant manual search, a group of infants aged 8-11 months performed Piaget's Stage IV task with an object hidden at successive locations in the vertical plane. (Author/JMB)

Peer reviewedHarris, P. L. – Child Development, 1973
Three experiments are presented which examine the ability of 10-month-old infants to search in a new hiding place. (Author)

Eight- to 12-month-olds might make A-not-B errors, knowing the object is in B but searching at A because of ancillary (attention, inhibitory, or motor memory) deficits, or they might genuinely believe the object is in A (conceptual deficit). This study examined how diligently infants searched for a hidden object they never found. An object was…

Results do not support Piaget's explanation of object conceptualization. (MB)

Peer reviewedMarcovitch, Stuart; Zelazo, Philip David – Child Development, 1999
Meta-analysis of the A-not-B error was conducted, using logistic regression, on studies conducted before September 1997. Results replicated earlier findings, with exception that the number of trials at the A location was a significant predictor, and the number of locations was a significant predictor of the proportion of infants who searched…
