Cephalic index viewed from above the head. The cephalic index or cranial index is a number obtained by taking the maximum width (biparietal diameter or BPD, side to side) of the head of an organism, multiplying it by 100 and then dividing it by their maximum length (occipitofrontal diameter or OFD, front to back).

In other words, the idea is that individuals' most basic needs must be met before they become motivated to achieve higher-level needs. [ 14 ]
