Final answer:
Kaden is likely to perceive racial and gender similarities due to the tendency to use these visible characteristics to inform immediate categorizations, influenced by stereotypes and identity importance.
Step-by-step explanation:
Research on how we categorize social information suggests that Kaden is most likely to perceive racial and gender similarities. This is because social categories of race, gender, and age provide significant information to an individual, often influenced by stereotypes. While economic differences are also important, the immediate categorization tends to focus on visible characteristics such as race and gender, as they provide a wealth of stereotypical information. Moreover, research, such as the work by Rogers & Meltzoff (2017), indicates that gender identity can be more meaningful than racial identity, especially in younger demographics.
