Age perception refers to how individuals interpret and judge the age of themselves and others. This perception can be influenced by various factors, including physical appearance, behavior, and cultural norms. For example, someone may appear younger or older than their actual age based on their lifestyle choices, such as diet and exercise. Additionally, age perception can affect social interactions and expectations. People often make assumptions about abilities and interests based on perceived age, which can lead to stereotypes. Understanding age perception is important in fields like psychology and marketing, where age-related biases can impact decision-making and communication.
