Infant search strategies with containers that move but do not alter the location at which contents can be found.
A number of hypotheses about infants' delayed search accuracy have been based upon the notion that a location associated with repeated retrieval of the object attains privileged status. Infants may need strong cues to search at a new location. However, a test is reported in which performance of 12- and 15-month-old infants was shown to be indifferent to the location. The results were reliable at an individual level. The data accord with previous research upon the canonicality effect in infant spatial search, an effect which is taken to index an experiential constraint on spatial discrimination. The experimental design thus serves as a discriminative test between three approaches: the original privileged location hypothesis, a newer spatial-contrast hypothesis, and a wider approach which focuses on experiential constraints on learning, including the canonicality effect.
