Figure 8.
Network performance on the Harris, et al (2008) task. The upper panel compares US activation patterns on element alone and compound trials when the network was trained concurrently with positive and negative patterning problems. The symbols are as in the previous figures. The lower panel displays network performance on a biconditional discrimination task. US activation patterns on reinforced compound (Cpd+) and nonreinforced (Cpd−) compound trials are displayed separately. See text for additional details.
