This study examines the perceived product longevity before and after consumption across different age groups and product categories. Hypotheses tested include the main effects of time and product category on perceived product longevity, and interaction effects between time and age, as well as between product category and age. The sample consisted of 49 participants divided into younger (under 40 years) and older (41 years and above) age groups. Using a within-subjects design, significant differences were found in the expected durability of products before and after usage, confirming Hypothesis 1. Although no significant interaction between age and time was initially observed, further analysis revealed significant complex interactions when product category was considered. Specifically, older participants expected longer product lifespans across all categories compared to younger participants, with automobiles showing the largest expected longevity, followed by household appliances and electronics. These findings highlight significant perceptual differences in product durability expectations, influenced by both age and product type. The results suggest that age significantly alters perceptions of product durability and interacts with product categories to influence expectations, providing valuable insights for marketers and manufacturers concerning consumer expectations and product communications.
