Figure 3.

Retention scores of experiments 1–8 (called same groups in Table 1). (A) Overall retention scores of the massed- and spaced-conditioned groups at the two test intervals (early LTM: 1 and 2 d after conditioning; late LTM: 3 and 4 d after conditioning). (B) Separate retention scores of the eight massed and spaced groups at the early LTM test interval (1 or 2 d). (C) Separate retention scores of the eight massed and spaced groups at the late LTM test interval (3 or 4 d).
