There is a general consensus that it is difficult to produce a basic list of human needs which satisfy all a designers requirements, however two general categories may provide the core route for the development of specialist checklists. These are biogenic and psychogenic. Biogenic needs, also described as primary needs, contain the basic physiological needs which when unfulfilled create feelings of deprivation that tends to overwhelm and dominate the individual’s attention, these include: hunger, thirst, sleep, sex, exercise, cleanliness, health. During a state of felt deprivation, these needs can become obsessive, however once the need has been satisfied others needs emerge and become more important until the condition is experienced once more. For example food intake is required at intervals according to life style, should the interval be extended beyond the norm the sense of deprivation and desire for satisfaction will grow, should it progress beyond endurance any intake of food will be acceptable no matter how awful (Chisnall, 1985).
Here will be a picture of Biogenic and Psychogenic Model of States of Felt Deprivation
Psychogenic needs, emotional and psychological needs are complex human behavior needs which emanate through cultural, social, emotional, and intellectual interests. These needs will have a bearing on the way in which biogenic needs are satisfied; for example the food intake may be combined into a social event or a cultural occasion where aesthetic requirements play a significant role. (Chisnall 1985)
A convenient classification of psychogenic needs may be affection needs, ego-bolstering needs, ego-defensive needs (Bayton 1958). These needs may apply in combinations, however there is often one that is most dominant or 'prepotent'. For example, customers may buy a new car because they need transport, but their dominant need may be to display a powerful image and position in society by demonstrating their wealth and exclusivity. While another new car customer may purchase their transport to get them to work, or for reliability because their last form of transport kept failing, or for economic reasons such as increased fuel economy or to escape rising maintenance costs.
