Frontal Deactivation and the Efficacy of Statistical Learning: Neural Mechanisms Accompanying Exposition to Visual Statistical Sequences

Description: BOLD activations during the viewing of visual stimulus sequences in healthy adults. Stimuli were presented in two conditions: abstract (DN) and easily nameable (EN). Sequences were either structured with a 1-Back statistical regularity (Statistic) or randomly ordered (Random). Figure 4 (N = 47): SPM maps for the two-tailed contrast Statistic>Random, illustrating areas of greater activation for structured sequences compared to random sequences, presented separately for DN and EN stimuli. Figure 7 (N = 41): SPM maps from partial-correlation GLM analyses with behavioral performance. For EN stimuli, significant clusters are shown for the Statistic>Fix contrast; for DN stimuli, significant clusters are shown for the Statistic>Random contrast.
