Figure 8. — Acquisition and 1-d retention after three-trial conditioning with 30-sec I_1–2 and different I_2–3 (A,B) and after two pairing trials with a 30-sec interval (I_1–2) and subsequent presentation of CS or US alone with a 10-min interval (I_2–3) (C,D). (A) Acquisition performance. The change in percentages of MERs to the CS with progress of training was statistically evaluated (Cochran's Q test: 5-min I_2–3, n = 23, P = 0.00019, χ² = 17.08; 10-min I_2–3, n = 23, P = 0.0045, χ² = 10.8; 15-min I_2–3, n = 24, P = 0.0047, χ² = 10.71; 20-min I_2–3, n = 22, P = 0.0084, χ² = 9.56; 30-min I_2–3, n = 24, P = 0.0023, χ² = 12.17). (B) One-day retention performance. The percentage of MERs to the CS was statistically compared with that to a novel odor in each group (McNemar's test: 5-min I_2–3, n = 23, P = 0.027, χ² = 4.9; 10-min I_2–3, n = 23, P = 1, χ² = 0; 15-min I_2–3, n = 24, P = 1, χ² = 0; 20-min I_2–3, n = 22, P = 0.0077, χ² = 7.11; 30-min I_2–3, n = 24, P = 0.0015, χ² = 10.08). (C) Acquisition performance after two pairing trials with a 30-sec interval (I_1–2) and subsequent presentation of CS or US alone with a 10-min interval (I_2–3). The percentage of MERs in the first trial was statistically compared with that in the second trial in each group (Cochran's Q test: CS only, n = 22, P = 0.002, χ² = 12.46; US only, n = 35, P = 3.06 × 10⁻⁷, χ² = 30.0). (D) One-day retention performance. The percentage of MERs to the CS was statistically compared with that to a novel odor in each group (McNemar's test: CS only, n = 22, P = 0.027, χ² = 4.9; US only, n = 35, P = 0.0055, χ² = 7.69). (*) P < 0.05, NS: P > 0.05.
