4.7. The Perceiver

Human beings are not just mechanical and passive recipients of stimuli from the external world. They are creative beings, and try to understand the external world in their own ways. In this process their motivations and expectations, cultural knowledge, past experiences, and memories as well as values, beliefs, and attitudes play an important role in giving meaning to the external world.

This chunk explains that humans actively interpret their environment rather than simply react to it. Our motivations—which refer to our needs and desires—significantly alter how we perceive things. For instance, when hungry, a person may view ambiguous images as food items, reflecting how their immediate desire influences their perception.

Imagine you are at a buffet after starving for hours; while looking around, you might see a shape on the table and immediately think it's a dish of food. On the other hand, if you just had a meal, you would interpret the same image as just a shadow or a decoration. This illustrates how your motivation (hunger) affected what you perceived.

The expectations about what we might perceive in a given situation also influence our perception. This phenomenon of perceptual familiarisation or perceptual generalisation reflects a strong tendency to see what we expect to see even when the results do not accurately reflect external reality.

Our expectations guide our perception of reality. If we expect to see a familiar person at a certain time and hear a knock on the door around that time, we might assume it's that person knocking. This illustrates a mental shortcut where we expect to see what we're familiar with, potentially leading to mistakes in our perception.

Think of an example where you are waiting for your friend at a café. You might hear footsteps and immediately expect your friend to arrive. If someone else enters, your brain might temporarily misinterpret that sound as your friend’s arrival. This expectation driven perception can lead to confusion or moments of surprise.

Cognitive style refers to a consistent way of dealing with our environment. It significantly affects the way we perceive the environment. There are several cognitive styles that people use in perceiving their environment.

Cognitive styles influence how we interpret our surroundings. For example, some individuals are 'field dependent' and perceive things holistically, while others are 'field independent' and analyze details separately. This results in different perceptions of the same scenario or object.

Imagine a group of friends observing a painting in a gallery. One friend might focus on the overall feel of the painting, appreciating it as a whole (field dependent), while another friend might analyze the brush strokes and color choices in detail (field independent). Both are valid perspectives influenced by their cognitive styles, demonstrating how our individual processing affects perception.

Different experiences and learning opportunities available to people in different cultural settings also influence their perception.

Cultural background plays a crucial role in shaping how we interpret visual stimuli. People from various cultural environments have different experiences that inform their perception. For instance, someone from a culture accustomed to interpreting flat images might struggle with three-dimensional representations.

Consider two groups of people: one group has grown up in a culture with rich art traditions that include depth in paintings, while the other group comes from a region where art is mostly two-dimensional. When asked to interpret a landscape painting, the first group may easily discern depth cues, while the second group may find it confusing and less realistic. This showcases how cultural familiarity affects our interpretations of visual information.
