...........,you are experiencing: concept formation
Concept formation is a process by which an individual develops the ability to respond to common characteristics of classes of objects or ideas. Concept formation allows an individual to group/classify objects or events that have similar characteristics intellectually. For example in terms of action, an individual picks up and wear a particular dress and in terms of thought the person appears to be concerned with classes (the style or color of the dress). This describes concept formation. From the question given, the person is likely experiencing concept formation because he is able to mentally class and differentiate (based on features) between what he saw and a house.
