Abstract
This chapter discusses the concept of homo informaticus—the individual organization member that performs complex cognitive processes, engages in decision making and satisfying of informing needs, and designs and evaluates information systems. Discussed are cognitive processes of thinking, feeling, perceiving, memorizing/memory recalling, and learning. These cognitive processes are involved in the fundamental informing process that starts with perception of external data, continues with applying knowledge to data, and ends with inferring information (meaning). Homo informaticus is typified based on Karl Jung's psychology and Kolb's learning styles. The discussion also addresses cognitive limitations. Memory is limited in volume and content, perception is prone to illusions, and thinking is susceptible to biases. These limitations influence the outcomes of informing, learning, and decision making.
TopHomo informaticus is the subject that performs high level cognitive processes. These are represented in Figure 1. The model depicts main cognitive processes of thinking, feeling, perception, learning, and memorizing as well as their corresponding states or structures signified in italics (thought, emotion, percept, and memory).
Figure 1. Cognitive processes and states
The central idea in the model is the relationships between cognitive processes and between them and cognitive structures. One should not infer that the relationships are linear. For example, the process of perceiving that is initiated by external data can be assisted by feeling and then by thinking, or thinking and then feeling. It may also happen that the process of feeling dominates the perception process, preempting room for thinking; e.g., an existentially grave situation can trigger an overwhelming emotion of fear, which further influences the perception process. Learning compounds some combination of other cognitive processes and structures, such as perceiving, retrieving of memory for previous knowledge, and thinking.
