D) faces.

Question

Quizplus · Accepted Answer

The preferential looking technique involves presenting infants with two grating stimuli of different spatial frequencies and recording their looking times towards each stimulus. Infants prefer to look at stimuli with higher spatial frequencies, indicating that they can discriminate fine details and have relatively good acuity. Other stimuli such as faces or Greebles may be used in other types of visual preference tasks, but they are not specific to testing infant acuity. Geons are basic shapes used in visual recognition and are not relevant to the preferential looking technique.
