Final answer:
Jason's inability to remember his first pet's name after a brain injury is an example of retrograde amnesia, which is a loss of memory for events before the trauma.
Step-by-step explanation:
After sustaining a traumatic brain injury, Jason could no longer remember the name of his first pet. This scenario describes an example of retrograde amnesia. Retrograde amnesia is the loss of memory for events or information that occurred prior to the traumatic event that caused the injury. Unlike anterograde amnesia, which is characterized by the inability to form new memories after the incident, retrograde amnesia affects memories that were formed before the trauma. Therefore, Jason's inability to recall the name of his first pet, which is a memory from the past, falls under retrograde amnesia according to Figure 8.10 in the provided information.
