Internal cues usually stimulate the desire to go to another location, and they will usually recognize a destination when they arrive. They may forget or never form a reason to go to another location. When they do have a reason, it is usually either hunger, thirst or a need to void.
A sense of direction seems to be an innate use of linear information that guides walking to a place in the physical environment. That linear information does not seem to be used within ACL 2.4 when people walk aimlessly or follow someone to go where they are escorted to.
Spontaneous, intentional use of the hands is not observed within ACL 2.6.
