## 3 DIKWP Semantic Interaction for Unidirectional Communication Impairments
### Purpose-Driven Decision-Making for Object Differentiation  
As infants observe and differentiate between various objects through their senses, they begin to recognize the categories or attributes of particular objects, even if these objects differ in visual (color, shape), auditory (sound), tactile (texture), or olfactory (scent) aspects. This recognition occurs because these objects share a set of critical semantic attributes. Through continuous sensory interactions, infants gradually form semantic spaces for various categories, allowing them to group objects with similar semantics into the same category. We use the DIKWP model to explain this process in detail. Through their cognitive experiences, infants continuously learn and iteratively form the semantic understanding and concept of a \"ball\". When an infant sees an object and identifies it as a \"ball\" based on semantic attributes such as \"shape\", \"tactile feel\", and \"sound\", this recognition occurs within the semantic space of \"ball\". When a \"red\" ball is introduced, it adds a color constraint to the concept of \"ball\" within the infant's understanding. Therefore, visually recognizing a ball as red, blue, or green reflects different and similar semantics. When the purpose is simply to identify a \"ball\", red and blue balls belong to the same semantic space category. However, when the purpose is to identify a \"red ball\", a blue ball would not belong to the same category as a red ball. As infants continue to iterate their object recognition, they link objects they need to identify with objects they already recognize in their semantic space. This process leads to forming either similar cognition (semantic similarity) or different cognition. Information semantics are confirmed or logically judged by recognizing differences in the cognitive space, resulting in distinct information semantics. Knowledge semantics, on the other hand, add dynamism and flexibility to knowledge concepts, allowing them to adapt to different cognitive tasks and environmental changes. Through continuous iterative cognitive processing, including data collection, information generation, knowledge construction, wisdom application, and purpose-driven action, the concepts and semantics of knowledge evolve interactively. The judgment of value within wisdom is a crucial aspect driven by purpose, remaining consistent regardless of changes in tasks or goals. Under different purposes, infants can accurately select targets and execute specific actions. The purpose of playing with a ball can be deconstructed into a dynamic semantic processing sequence, starting from the initial perception of the \"red ball\" (input) and progressively building toward the specific goal of wanting to play with the ball (output). This further develops into sub-purposes like bouncing, chasing, or pushing the ball (outputs). While playing with the ball, the infant deepens their understanding of the \"ball\" through practice and forms a more complete DIKWP semantic space, as shown in Figure 6.  
The purpose-driven infant semantic space decision for \"playing with the ball\" is as follows:  
**A. Sensory System Input**  
_Object = \(\{\)RedBall, Balloon\(\}\)_  
Figure 6: DIKWP semantic space interaction for infant recognition of the “red ball”. \(Input=f_{Sensory}(object)=\{Sight,Hearing,Smell,Touch\}\)  
**B. Target Semantic Space Formation**  
\(\exists t_{0}(f_{Sensory}(RedBall)\to S_{RedBall}(t_{0}))\)  
\(\exists k_{0}(f_{Sensory}(Balloon)\to S_{Balloon}(k_{0}))\)  
Through continuous sensory interactions, the infant forms the semantic space for the red ball at time \(t\) and the semantic space for the balloon at time \(k\).
