Enhanced performance at a higher level of the PAL task
may represent strengthened competency in the specific network
underlying episodic memory, yet importantly, we also
found improved functional outcome in the CT group as
measured by the GAF at outcome assessment. This suggests
that the effectiveness of our memory game might not be limited
to improved episodic memory, but it also has the
potential to improve functioning in activities of daily living.
This functional improvement could be driven by several possible
mechanisms. For example, improvements in memory may
have had a direct impact on global functions. An alternative
explanation is that CT may have had an indirect impact on
functionality by improving low self-esteem. Or indeed, both
of these explanations may have played a role in terms of the
impact of training on functional outcome
