Final answer:
Chou with anterograde amnesia will struggle to remember new information learned after the diagnosis, as this condition impairs the ability to form new episodic and semantic memories.
Step-by-step explanation:
Chou, who was recently diagnosed with anterograde amnesia, will be least likely to remember information learned after the diagnosis. Anterograde amnesia is a form of memory loss where an individual is unable to form new episodic or semantic memories following the onset of the condition, although their procedural memory may still function. This means that while Chou might remember events from childhood, the names of family members, and other experiences from before the diagnosis, they will struggle with retaining new information or experiences that occur after they have developed amnesia.
