Final answer:
The motivation to perform an activity due to external goals is referred to as extrinsic motivation, which is considered true.
Step-by-step explanation:
The question is asking about the motivation to engage in an activity due to the external goals that the activity is directed towards. This is known as extrinsic motivation, which involves performing an action to achieve external rewards or to avoid punishments instead of for the action's own intrinsic value. An example of extrinsic motivation would be when someone studies hard to receive a good grade (the external goal) rather than for the enjoyment of learning the material itself (which would be intrinsic motivation).
So, the motivation to perform an activity because of the external goals toward which that activity is directed can be labeled as true, as this is the definition of extrinsic motivation.
