From Savolainen on Nahl: "The model connects information behavior to two particular biological functions of the human affective system: infor- mation reception and information use. Of these, information reception denotes the processes of information searching or seeking, including in- formation encountered incidentally. The model demonstrates that in- formation behavior consist of a continuous dynamic flow of individual biological procedures in an attempt to adapt and cope within a context (Nahl, 2007a). The affective subsystem deals with emotions and moti- vations, and it determines the consummatory value of the information first appraised by the cognitive subsystem. More specifically, the affec- tive subsystem is involved in promoting the information seeker's confi- dence and satisfaction. The affective subsystem also includes the continuous motivational energy provided by one's intent, goal, purpose, use, aswell as the emotional dynamic features that determine the qual- ity of the search process. The emotional features include perseverance, frustration, hope, disappointment, excitement, and disbelief, for example."
