Which of the following is a personal determinant that influences consumer behavior?

The factor of learned experience as a personal determinant influencing consumer behavior is grounded in the concept that individuals develop preferences and decision-making frameworks based on their past interactions with products and services. This personal experience shapes how a consumer perceives value, quality, and relevance of a product or service in their purchasing decisions.

When consumers engage with a product, they form expectations based on previous experiences—whether those experiences are positive or negative. For example, if someone has consistently found that a particular brand of toothpaste effectively meets their oral health needs, they are likely to return to that brand for future purchases. Similarly, negative experiences can deter consumers from re-purchasing or exploring that brand again.

In contrast, the other options pertain to external influences or broader market dynamics rather than personal determinants rooted in individual psychology or past interactions. Market trends involve general industry movements and consumer preferences over time; peer influence deals with social factors and relationships that impact decision-making; while product availability refers to the presence or lack of products in the market, affecting access rather than personal affinity or prior experience with a product. These factors, while significant in their own rights, do not stem from an individual's direct, personal history with a product as learned experience does.
