The nonlexical pathway is thought to be more active and constructive as it assembles and selects the correct subword units from various potential combinations. For example, when reading the word "leaf", that adheres to spelling to sound rules, the reader must assemble and recognize the two-letter grapheme "ea" in order to produce the sound "ee" that corresponds to it. It engages in controlled processing and thus requires more attentional capacities, which can vary in amount depending on the complexity of the words being assembled. On the other
