Could put a picture in front of a person and ask them for their impressions of the picture, or give them an object. Sensors will more likely first notice the colors, shapes, forms of the object. Even will a well-researched perspective of the picture, they will still focus on how it looks, what is really there, or based on their experiences. Intuitives will look for hidden meanings behind the picture, or fuse their own personal abstract connections to said picture.
Could use a picture of an apple and ask someone to give their interpretation of it.
For sensors:
Se- focus on the color, shape, size, taste, texture, shadow. "That apple looks shiny and red." Will likely take said apple and eat it, or play around with it in their hands, examining what it looks like. More likely to savor the flavor of the apple, take in as much characteristics of the apple as they can. They will likely describe these characteristics more. This will be second nature to those with Se.
Si- focus on how said color is the "proper" color of an apple, "proper" size and shape of it. Recalling what type of apple it is, how properties of how it looks, feels, tastes, are related to the variety of apple. Past memories and experiences associated with apples (i.e. Mom's apple pie), and how it makes them feel. Focusing on ageless customs associated with apples, for instance making apple pie during Thanksgiving or Christmas. Or they may focus on the fact that the apple doesn't look the same as ones they are used to, doesn't taste the same. "This is how we've always done things with apples." This will come naturally for those with Si.
For intuitives:
Ne- focus on the implied meaning of what apples are. Apples signify "knowledge", "learning", "temptation", and juggling with the varying interpretations of what the apple represents, thinking all interpretations are true. "This apple implies A, B, C, D, and they all have a unified theme, which ties into knowledge/learning." They will brainstorm aloud what the possible meanings are behind the apple, and find a unified theme by bouncing ideas off of someone else. They would likely use an apple to create change in a social atmosphere, "let this apple help you to find your path to knowledge." This will come instinctively to one with Ne.
Ni- Will focus on what the apple symbolizes for them in their own personal goals and dreams. Apples being a symbol of the wisdom they seek in their pursuit of higher enlightenment, for instance. To achieve higher insight, an Ni-dom will focus on the apple and how it's made up of a certain type of atoms, cells, the inner workings of how it formed. This will help them to understand how plants work, for learning's sake. They will also focus on how it's also a part of the plant's reproductive cycle, and relate it to their own transformation, perhaps one's own way of bearing fruits in the pursuit of their goals. They may connect it to seemingly unrelated abstract concepts in their mind, be it a piece of music or literature, that also represents the same symbolic connection. It becomes a driving symbol for their personal journey to deeper understanding. Even the falling of an apple may be connected to an intuitive's connection to what they think will happen in interpersonal relationships, as well as it being an omen of what will come in the future. More likely to use apples to speak in metaphor about a goal or dream they wish to achieve. This will come instinctively to one with Ni.
