If a word is cognitively synonymous with another word, they refer to the same thing independently of context.Thus, a word is cognitively synonymous with another word if and only if all instances of both words express the same exact thing, and the referents are necessarily identical, which means that the words' interchangeability is not context-sensitive.
The functional-equivalency hypothesis is that mental images are "internal representations" that work in the same way as the actual perception of physical objects. [33] In other words, the picture of a dog brought to mind when the word dog is read is interpreted in the same way as if the person was observing an actual dog before them.

[1] The mental lexicon is used in linguistics and psycholinguistics to refer to individual speakers' lexical, or word, representations. However ...
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire ...

[ 1 ] In perceptual psychology , a stimulus is an energy change (e.g., light or sound) which is registered by the senses (e.g., vision, hearing, taste, etc.) and constitutes the basis ...

Lastly, we have semantic processing in which we encode the meaning of the word with another word that is similar or has similar meaning. Once the word is perceived, the brain allows for a deeper processing.
