The rule expectancy effect on the electrophysiological correlates underlying numerical rule acquisition.

The present study aimed to provide electrophysiological evidence about acquiring complex numerical rules when unexpected numbers were presented. Hence, we compared the neural correlates underlying the acquisition of unexpected complex rules (e.g.

Relational complexity modulates activity in the prefrontal cortex during numerical inductive reasoning: an fMRI study.

Most previous studies investigating relational reasoning have used visuo-spatial materials. This fMRI study aimed to determine how relational complexity affects brain activity during inductive reasoning, using numerical materials. Three numerical relational levels of the number series completion task were adopted for use: 0-relational (e.
