Recall performance and memory organization. (A) Probability of recall was greater for strong (blue) compared to weak (orange) semantic associates and was greater for first compared to second associates. There was a significant interaction between associate and semantic association strength (P = 0.006). The boxes denote the interquartile range, the horizontal bars denote median, and the whiskers denote minimum and maximum values. (B) Probability of recall was greater for strong than weak semantic associates across serial positions. Error bars denote standard error of the mean. (C) Participants were more likely to make transitions between strong compared to weak semantic associates. The vertical, dashed line denotes the boundary between weak semantic bins (below 0, 0.0–0.2, 0.2–0.4) and strong semantic bins (0.4–0.6, 0.6–0.8, 0.8–1.0). Error bars denote standard error of the mean. (**) P < 0.01, (***) P < 0.001.
