title: Children's memory for orientation in the absence of external cues.
abstract: Some have interpreted children's reliance on external visual cues as evidence that they are unable to use internal cues for orientation. This hypothesis was examined in experiment 1, where 24 preschoolers were tested on left-right, vertical-horizontal, and mirror-image oblique discriminations under essentially context-free conditions. Subjects succeeded on all discrimination problems and performed equally well on vertical-horizontal and mirror-image oblique discriminations. Thus, preschoolers can use an internal frame of reference to code orientation. Experiment 2 contrasted children's performance under context-free conditions with their ability to discriminate orientation in the presence of external visual cues. Children who had discriminated left-right oblique and nonoblique mirror-image forms in experiment 1 failed to so discriminate in experiment 2. This result is discussed in terms of a breakdown in the ability to use internal cues when external visual cues are available.
