Fig. 4.
Estimates of blood-oxygenation-level-dependent activation in both hippocampal regions (reported in Fig. 3), based on corresponding accuracy across conditions. Results for the right hippocampus are shown in (a) through (d). The observed and the fitted peak percentage signal change for the three serial-position (SP) groups (passive set: SPs 1–8; active set: SPs 9–11; focus of attention: SP 12) is shown in (a). The observed and the fitted peak percentage signal change across SPs is shown in (b). Bars indicate the data; the line indicates the fit with Equation 2. The observed and the fitted peak percentage signal change for the three SP groups when redefined on the basis of individual participants’ behavioral data is shown in (c). The observed and the fitted peak percentage signal change across SPs when redefined on the basis of individual participants’ behavioral data is shown in (d). The bars indicate the data; the line indicates the fit with Equation 1. Corresponding data for activation in the left hippocampus are shown in (e) through (h).
