Figure 6. Comparison of spontaneous recovery of fear memory in each group. Note. E: Traditional extinction group, R1: Single-retrieval extinction group, R2: Double-retrieval extinction group, R4: Quadruple-retrieval extinction group. Spontaneous recovery index = spontaneous recovery of the first trial of SCR value - extinction of the last trial of SCR value (Schiller et al., 2010). *p < 0.05, **p < 0.01
