Haptic communication many terms such as positive, playful, control, ritualistic, task-related or unintentional. It can be both sexual (kissing is one example that some perceived as sexual), and platonic (such as hugging or a Handshake). Touch is the earliest sense to develop in the fetus. The development of an infant's haptic senses and how it relates to the development of the other senses such as vision has been the target of much research. Human babies have been observed to have enormous difficulty surviving if they do not possess a sense of touch, even if they retain sight and hearing. Infants who can
Haptic memory stimuli. According to a study done by Bruce V. DiMattia, Keith A. Posley and Joaquin M. Fuster, it was found that monkeys were quite capable of concurrent Visual-to-Haptic as well as Haptic-to-Visual crossmodal matching of objects by size, shape and texture. It was also discovered that they were more adept at performing cross modal matching in the Visual-to-Haptic direction. Memory is important in infancy as it forms the basis for more complex procedures such as learning and reasoning. Studies of haptic memory in infants is particularly useful because it allows researchers to study the more perceptual representation of information as
