Figure 4

Average deoxyHb concentration over time. Analysis of deoxyHb concentration during the first four blocks and the last four blocks revealed a significant interaction between condition and time (p = 0.025), with a significantly larger deoxyHb response for the ABC grammar during the early blocks than the later blocks (p < 0.02) and no change in ABB grammar responding across time (p = 0.45). Additionally, a marginal interaction was found between condition and age (p = 0.056). One-sample t-tests revealed that the 7-month-old ABB response during Blocks 1–4 and the 9-month-old ABC response during Blocks 1–4 are significantly different from zero. Error bars represent ±SE.
