Do not use "perceiving that" when you are describing a simple, literal observation with no interpretive element. For example, use "seeing the red light" instead of "perceiving that the light was red" unless you specifically intend to discuss the mental process of color identification.

Linguistic Context
The phrase "perceiving that" functions as a present participial phrase followed by a complementizer. In this structure, "perceiving" acts as the head of the phrase, governing a subordinate "that" clause which functions as its direct object. This construction is highly effective for establishing a character's or subject's viewpoint within a narrative or scientific report. Ludwig AI confirms this as a standard and correct way to introduce cognitive or sensory states.

Ludwig's WRAP-UP
In conclusion, "perceiving that" is a robust and grammatically correct expression favored in sophisticated writing. As Ludwig AI suggests, it is typically used to indicate that someone has become aware of something through observation or inference. Whether in a scientific context discussing sensory reactivation or a historical narrative describing a general's tactical shift, the phrase serves as a precise tool for articulating the intersection of sight and thought. By using alternatives like "sensing that" or "discerning that", writers can further refine the specific type of awareness they wish to convey.
