Final answer:
Without specific information on the family's awareness and understanding of synesthesia, it's difficult to assess how they would treat the member with synesthesia. A supportive family might be inquisitive and accommodating, whereas a less understanding family could be confused or dismissive. Like in Rosa's case, cognitive changes often lead families to react with concern and urge medical help.
Step-by-step explanation:
The question does not provide enough information about the individual's family's reactions post-discovery of synesthesia to give a definitive answer. Synesthesia, a condition where one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway, could lead to a family treating a member differently based on their level of understanding and acceptance of the condition. If they are supportive, they may show curiosity and a willingness to accommodate or assist with the unique perceptions associated with synesthesia. Alternatively, a lack of understanding might result in confusion or dismissiveness toward the individual's experiences.
In cases similar to Rosa's, where cognitive changes such as memory lapses and mood swings are apparent, families might react with concern and encourage medical consultation. A diagnosis, whether it be synesthesia or any other cognitive condition, can sometimes lead to changes in family dynamics and the way an individual is treated, largely depending on the knowledge and emotional response of the family members. The support and reactions can significantly affect the individual's coping mechanisms and quality of life.
