The interference of a baseline with children's orientation judgement need not entirely mask their contextual responsiveness

Children below the age of seven are very influenced by the orientation of the external frame of reference when they attempt to lay down a stimulus to match that of a tilted target. If, however, the target be set upon a baseline the children seem unable to benefit from salient parallel alignment cues. By modifying the usual design it is shown that children can remain able to take their bearings from contextual alignment even when setting a pointer upon a baseline; but the effect is only revealed in a complex three-way interaction. Contextual sensitivity is thus not abolished, but masked; and its re-emergence is in an apparently anomalous form.
