Using mobile devices

The technological trend affecting consumer behavior among the options you provided is "using mobile devices".

The technological trend that affects consumer behavior among the options provided is "using mobile devices." This trend has significantly impacted how consumers interact with brands, make purchases, and consume information.

To arrive at this answer, I evaluated each option and considered its relevance to technological trends.

- "Evaluating purchases" is a consumer behavior related to decision-making but not necessarily tied to technology.

- "Having reference groups" is a social aspect of consumer behavior that focuses on individuals seeking guidance or inspiration from others. While technology can facilitate the access to reference groups (e.g., online communities, social media), this option is not explicitly a technological trend itself.

- "Meeting affiliation needs" is a broader concept related to human psychology and socialization, which is also not solely influenced by technology.

However, "using mobile devices" is a clear technological trend affecting consumer behavior. With the widespread availability of smartphones and tablets, consumers can now access information, browse products, and make purchases anytime and anywhere. Mobile devices have revolutionized the shopping experience, enabling consumers to research products, read reviews, compare prices, and make informed decisions conveniently. This trend has led to a significant shift in customer behavior and has forced businesses to adapt their marketing strategies to cater to mobile-first consumers.
