Information and knowledge about the world come to us only through our sensory and perceptual apparatus. Because the fetus has limited access to the world, investigators who are interested in the development of sensory and perceptual processes find a natural starting point in the very young infant. My purpose is to provide readers with an overview of what we know about the sensory and perceptual status of the infant in the first year or so of life. I will also try to convey a sense for the methods that have been designed to yield information from organisms who cannot speak, who cannot understand our instructions to respond, and who do not possess the motoric competence to do so even if they did. Several excellent reviews and chapters exist for the reader who desires extensive coverage of this topic (see, for example, references 1 through 5). Therefore, the attempt here is illustrative rather than exhaustive.The paper is organized by sensory modality: touch vestibular sensitivity, smell and taste, hearing, and vision. This sequence follows, roughly, the developmental onset of function in vertebrate species. 6 But the coverage of sensory modalities cannot be even. Audition and vision have attracted much more attention than the other senses, and vision, especially, enjoys more elaborate concepts and techniques. Thus the discussion of visual processes outweighs those of other modalities, and includes how perceptual competencies are deployed by the infant to acquire and organize the unlimited information with which he or she is confronted.
