How is INFLectional morphology more like Chomsky and how is DERIVational morphology more like Skinner? Explain. Recall that Chomsky addresses rule-based language while Skinner addressed memory of word. One could do a brief research review of how school children (1-3 grade) have more trouble with INFL as opposed to Deriv morphology. So, there is a pedagogical issue here between the two types of morphology (Horizontal X+Y=Z/Rules vs. Vertical X=X/word).
