Blurting out is the function of which consciousness?

Which consciousness's function does blurting out reveal? Is it the sixth consciousness or the seventh consciousness that is in charge? It is the functional activity of the seventh consciousness, the manas. When He contacts sense objects, He immediately knows the object-realm, makes a decision, and has a reaction, not allowing the mind consciousness to deliberate further, without the mind consciousness needing to consider again—He makes the decision arbitrarily and unilaterally, and the six consciousnesses instantly comply. Afterwards one may regret it; this is because after the mind consciousness has analyzed and deliberated, it feels that what was just done was wrong, too rash, and so one feels regret.
