Definition

Retention and protention name Husserl’s paired horizons of the lived present: the just-past remains operative while the next moment is already anticipated. They make temporal objects such as melodies intelligible as unfolding wholes. The corpus uses this phenomenological structure alongside predictive theories without reducing it to neural error correction or deliberate recollection and forecasting.

Explanation

The currently sounding note is heard within the fading presence of preceding notes and an expectation of continuation. Retention is not a later act of adding memory to an otherwise isolated instant. Protention likewise belongs to the organization of experience before explicit reflection formulates a prediction.

AB describes surprise as depending on an expectation already under way; without these horizons, melody and sentence would fragment into disconnected moments. PB supplies a condensed formulation of the temporally spread present, retaining the relation between the note heard, retained and awaited.

RB2 places this account beside Rosen’s biological anticipation and predictive processing. The convergence is suggestive rather than an identity: phenomenology characterizes lived temporal unity, whereas neural and organizational theories explain other aspects of anticipation. Neither register automatically supplies the complete warrant for the other.
