comprehensive model for the characterization of cognitive processes

Introduction: To propose a model for the determination and characterization of mental activities. Materials and methods: The cognitive processes under study are analyzed into six cognitive events according to Bloom’s taxonomy. For each cognitive event the 6 dimensions including the cognitive activities are assigned using the relevant action verbs using ontology measures. The input and the output concepts are defined for each event in sequence of the cognitive process. The internal relations and the input relations as well as the output relations are described. The alternative routes for a given cognitive process are compared to judge on the best and optimal processes. Results: In our model four major assumptions are considered as the bases of this model. First, it is supposed that a cognitive process exists underling every task performance by an individual. Second, we presume that in every cognitive process there are six hierarchical levels of cognitive events, as worked up in the Bloom’s taxonomy revision study during 1996 to 2001 namely: remembering, understanding, applying, analyzing, evaluating and creating. Third assumption poses that every mental process including a sequence of some cognitive events each characterized by a 6-tuples, as elaborated by Xujie Zhang and colleagues and defined by e= formula. The last and the fourth assumption implies that the basic unit of cognition is concept, that is characterized by a 5-tuple. In cognitive informatics, logic, linguistics, psychology, software engineering, and knowledge engineering, concepts are identified as the basic unit of all thinking processes and sub-processes. An abstract concept c on a semantic context is a 5-tuple, and formulated by Yingxu Wang as:c = (O, A, Rc, Ri, Ro). Concept is the currency of thinking as the output of one cognitive activity and the input of another in the sequence of events of a cognitive process, as previously mentioned. Conclusion: Testing the model by the exam questions in medicine showed that for every cognitive task performance different and specific cognitive processes may be employed, depending on the subject, objectives and their properties including: the concept characteristics and the event features. The type of each activity is identified by the action verbs allocated to each cognitive event, according to Bloom’s taxonomy.
