An educational psychologist is studying how students retain information during online lecture slides. They present a list of 16 distinct astronomical terms (e.g., nebula, pulsar, quasar) sequentially on a projector screen, with each term shown for 2 seconds.

• Cohort Alpha: Students are asked to write down as many terms as they can recall immediately after the final slide is shown.
• Cohort Beta: Students are asked to write down as many terms as they can recall only after counting backwards in threes from 999 for 30 seconds.

The psychologist's results show:

• Students in Cohort Alpha achieved high recall accuracy for the first few terms and the last few terms of the sequence.
• Students in Cohort Beta achieved high recall accuracy for the first few terms, but very low recall accuracy for the last few terms.

Explain these findings with reference to the multi-store model of memory.
