Definition for PERCEPTION:
Perception is the process of selecting, organising, and subjectively interpreting sensory data in a way that enables us to make sense of our world.
Stages of Perception:
1) The selecting stage, during which we attend to only some stimuli from all those to which we are exposed
2) The organising stage, during which we give order to the selected stimuli
3) The interpreting/evaluating stage, during which we make sense of or give meaning to the stimuli we have selected and organised based on our life experience
4) The responding stage, during which we decide what to think, say or do as a result of what we have perceived
Barriers to Perception:
a) Perceptual sets
Past experiences often provide us with expectations, or perceptual sets, that affect how we process our world.
Past experiences create perceptual sets in numerous ways e.g. culture, motivation, education, etc.
Education example: When asked to interpret a certain stimulus, a sociologist, an economist, or biologist might bring her or his specific professional bias to the assignment, which could blind each person to other possible interpretations.
b) Selectivities
Four types of Selectivities:
Selective Exposure – The tendency to expose ourselves to information that reaffirms existing attitudes, beliefs and values; the tendency to close oneself to new experiences. Example: Just as children sometimes place their hands over their ears to avoid hearing what their parents are saying.
Selective Attention – The tendency to focus on certain cues and ignore others. Example: You are more apt to overhear someone seated near you speak of wanting to buy a house if you are a real estate agent than if you are in computer sales.
Selective Perception – The tendency to see, hear and believe only what we want to. Example: We tend to overlook negative qualities in people we like.
