This is a research study of experimental psychologists who have been seen to use non-human animal species and the human infants to establish quantitative relationships between perceptual and sensory experience and physical stimulation. Many studies have so far revealed the importance of using very young infants or animal-based research in exploring the complexities in nature of what they perceive. This study specifically aimed at utilizing coordinated studies of very young human infants and non-human animal, guided by Gottlieb’s pioneering vision to identify patterns of perceptual processing and selective attention that is common across species in early developments. It also aimed to examine human developments in the brain and mind. Gottlieb used his work to demonstrate the importance of using animals in researching behavioral, perceptual, or social development is to the ability to modify the timing, type, or the amount of experience available to the infant or embryo.
