What psychological factor can influence perception according to the concept of perceptual set?

The concept of perceptual set refers to the predisposition to perceive things in a certain way based on expectations, experiences, or psychological factors. Emotional state is one of the key psychological factors that can influence this perception. When individuals are in a heightened emotional state, such as being happy, anxious, or sad, their perception can be skewed by these feelings. For example, someone who is feeling happy might interpret neutral stimuli more positively, whereas someone who is feeling anxious might perceive the same stimuli as threatening.

This predisposition forms a mental framework through which information is filtered, effectively shaping how experiences and stimuli are understood. The emotional state can prime a person to expect certain outcomes or interpretations, thus influencing their perception of various scenarios.

In contrast, while physical condition, cognitive dissonance, and environmental noise can affect how information is processed, they do not primarily embody the concept of a psychological factor that shapes interpretation based on previous experiences or emotions in the same way that emotional states do. Therefore, emotional state stands out as the primary influence within the context of perceptual set.
