 Meinong (1906, §§11 and 13; 1910, §43) thinks that attention allows us to do two different things with one and the same experience and content respectively: (1) If we direct our attention to our inner experience, for instance, to the red content of a representation of red, this very content serves for the inner perception of itself — the red-content becomes an intended object and serves for the apprehension (perception) of itself. He also says that in this case the content becomes turned inwards (introversion, [Einwärtswendung]). (2) If the content contributes to a perception or a thought of something red, the content concerns something external to the mind — it serves for the apprehension of the coordinated outer objects and can therefore be called turned outwards (extraversion, [Auswärtswendung]).
