Summary

Haptic processing subserve perception and action. During the first year of life, an infant's developing perceptual, motor and cognitive capabilities are coupled. Touch experiences are largely involved in cognitive development. Infants can perceive and understand the physical world with their hands alone.

Object names map to physical objects; they appear to be the most prevalent words in infants' early lexicons in the period of single-word utterances. The nature of their representation is complex. A concept is formed by transforming a sensorimotor schema into an image-schema. Conceptual knowledge is the most important aspect in how to generalise an object's name. Concerning the haptic system for word-learning, it is absolutely essential in the cognitive canon of modal representation for non-verbal categorisation, since infants interactively integrate object information from all sensory modes, especially the haptic mode - the first functioning system in utero is touch. Haptics offer a sensorimotor organising structure for non-verbal categorisation in early learning of object words. Because objects are discrete, they are more easily conceptualized.

There are at this time no plausible correlational hypotheses for any other types of word and object categorisation. Verbs enter the individual vocabulary much later than nouns and at a slower rate [4], since it is harder to form concepts for actions as opposed to objects. Semantic representation of objects and actions are different, because noun-meaning is more restrictive than verb-meaning. Compared to objects, actions are intangible and transient. The relationship between linguistic input and non-linguistic categorisation has not been sufficiently specified.
