| - | These two kinds of processing systems result in two types of stored representations: | + | The two mentioned kinds of processing systems, **verbal and non-verbal** are functionally and structurally independent. This means that each of them can work independently of the other one and that they work on different kinds of representational units. Representational units are "//relatively stable long-term information corresponding to perceptually identifiable objects and activities, both verbal and nonverbal.//".(()) They are divided into: |
| - | * **logogens**, referring to verbal entities and organized in terms of associations and hierarchies, and | + | * **logogens**, referring to verbal entities (spoken or written words) and organized in terms of associations and hierarchies, and |
| * **imagens**, referring to mental images and non-verbal entities and organized in terms of part-whole relationships. | * **imagens**, referring to mental images and non-verbal entities and organized in terms of part-whole relationships. | ||
| - | Logogens and imagens are connected with two kinds of relations: | + | For example, a written or spoken word will be processed using the verbal processor and stored as a verbal representation - logogen, but a sound not related to language will be processed by the non-verbal processor and stored as a non-verbal representation - imagen. Logogens and imagens are connected with two kinds of connections: |
| * **//Referential connections//**, which represent links between logogens and imagens. Referential connections enable performing operations like imaging to words and namings to pictures or images to words. For example, associations of an image of a school building or an unpleasant feeling (both non-verbal entities) elicited by the word //school// (a verbal entity). | * **//Referential connections//**, which represent links between logogens and imagens.

| + | Pavio also refers to the issue of problem-solving. Problem-solving is, according to Pavio, the result of joined work of both verbal and non-verbal processing, but if the task is more concrete and non-verbal, the contribution of non-verbal processing system will be more crucial to the outcome and vice-versa. | ||
