Antecept

It is a difficult question whether the serial principle permits us to draw sharp lines of demarcation between the percept and the near anticipation, or say the antecept, and between the percept and the recent memory (may I be permitted to call this the ponecept, a distant and dubious memory being perhaps quite another thing?), or whether the percept is at once but an extreme case of an antecept and an extreme case of a ponecept.
