Science-Fellows® As previously stated, cognition is the encoding, structuring, storing, retrieving, using, or otherwise learning knowledge (Neisser, 1967). There are important developmental aspects for each of these activities. According to Flavell et al. (2002), from an information processing perspective some of the most important are: 1. 2. 3. 4. 5. Brain changes brought about by biological maturation or experience; Increased processing capacity, speed, and efficiency as a result of both maturation and knowledge development; Modifications of connections in a neural network; New emergent concepts arising from repeated self-organization as a result of adapting to the demands of a changing environment; and Increased capacity for problem-solving and metacognition. Encoding Encoding occurs during the initial processing of a stimulus or event. Maturation and experience influence this process. In terms of maturation, Dempster (1981) suggests that the adult capacity for short-term memory of 5 + 2 digits might be as much as 2 digits lower for children aged 5 and 1 digit lower for children aged 9. As for experience, in a series of well-known studies of expertise, novices remember new information less well than experts (e.g., Chi, 1978; Schneider, Korkel, & Winert, 1989). One of the most important differences between novices and experts is the structure and organization of domain-specific knowledge. Structuring and Organizing Structuring and organizing information occur as the learner processes and stores information. The learner’s ability changes over time as a result of both maturation and experience. When presented with information they are asked to remember, younger children do not rehearse ElmCore® Journal of Educational Psychology information in order to remember it. As they get into school, they begin to develop or are taught various strategies. At first these strategies are only used when prompted by someone else, but as the child becomes more competent in their use and uses them more frequently, the child will increasingly use the strategies spontaneously (Flavell et al., 2002).
