Final answer:
Antecedent states include internal factors such as mood, cash on hand, and physiological conditions, which impact consumer purchasing behavior prior to entering a purchase environment. Options like customer preferences, other people present, market trends, and product features are related to different categories, not antecedent states.
Step-by-step explanation:
Antecedent states are internal factors that influence a consumer's decision-making process prior to entering a purchase environment. Besides the purpose of the purchase, antecedent states include the consumer's mood, the amount of cash on hand, and physiological factors. These states can significantly alter a person's purchasing behavior.
While customer preferences are certainly a part of the decision-making process, they are not usually considered antecedent states as they are more related to consumer characteristic influences.
The other options provided: other people present (social factors), market trends (external environmental influences), and product features (product-related factors) do not fall under the category of antecedent states as they exist outside the consumer prior to the purchasing process.
Instead, antecedent states typically refer to those factors that are inside the consumer and are brought into the purchasing situation, including but not limited to: emotional state, stress level, and general attitude towards shopping at that moment.
These personal factors can substantially affect what consumers buy, how much they spend, and whether they experience buyer's remorse afterward.
