The EVD concept is very useful in Database designing procedure and in conceptual schema design. Designing of a Database is considered as a systematized process that moulds data into a structure which is similar to the underlying system of database management model. Systems of database management are categorized into three main types:

Research Methods in Cognitive Level of Analysis There are 3 research methods can be used in cognitive level of analysis. They are lab experiments‚ case studies of patients with brain-damage‚ and brain imaging techniques. The methods are basically the same methods used in biological level of analysis. These methods are useful depending how the researchers want to study the cognitive process. One of the most scientific ways to study mental processes is through lab experiments because the high

1. Discuss the topic of social cognition and in particular the role of heuristics in the way we process information. Briefly describe two different heuristics and give examples of how and when they might be used as well as problems connected with their use. The manner in which we interpret‚ analyze‚ remember‚ and use information about the social world is known as social cognition to social psychologists. This process has a large effect on our daily lives as we interact socially. The thought processes

mental representation‚ this is what we call schemas. Our mental representations are the meaning that we give to objects‚ people and events that we experience. We used this to solve problems and make sense out of the world. The information we use to create a schema are gathered through our senses e.g smell‚ hearing‚ vision‚ taste and touch then it goes to our brain to be processed and made into our schemas. This is what we called assimilation. Schemas are not permanent sometimes due to a bad experience

HOW IMPORTANT ARE MENTAL REPRESENTATIONS IN COGNITIVE THEORIES? How the world around us is represented mentally is the corner stone of cognitive architectures. It facilitates understanding of information received and perceived from our environment. The storage and retrieval of knowledge would be impossible without mental representations. Mental representations are the way in which we create copies’ of the real things around us‚ which we perceive. A description of a representation is a symbol
