Working memory in children: tracing age differences and special educational needs to parameters of a formal model

This study is related with the working memory in the early childhood and the difficulties faced in learning by children. This article discusses the research made in past two years. Working memory is described as a storage system storing limited number of independent items with a selective access. The study also found that the difficulties in learning in children with special needs. The disability was found in children of various ages but the disability increased with the learning deficits. Deficit in verbal domain was found in age-matched working memory. Spatial disability was found in mixed results. This study tested one theoretical perspective related to the working memory to trace differences in development. Verbal and spatial task were administered to children for memory-updating tasks. Interference model is also presented for the description of the representational aspects. The interference measurement is assumed of bounding one element to one feature only. Overlapping of features in elements creates problems and loss of certain properties of the features. The second assumption related to the interference is that the activation is not selective with the attention of the ring.

There are four parameters of interference memory. First is average proportion of feature overlapping; standard deviation of internal noise and two processing rates. The article further links the parameters of learning difficulties to general disabilities. There are three levels of Dyslexia. At the biological level, the dyslexia may occur due to hereditary factors. A person with cognitive level dyslexia has problems with information processing and sequencing ideas. For this person, lengthy instructions mean an inability to comprehend what has been asked of the person. For people suffering from dyslexia at the behavioral level, the difficulties may include a difficulty with reading and learning to read, difficulty with handwriting and speech impairment. Their mathematical skills are also subordinate to the skills of an ordinary person. Moreover, they have difficulty in rhyming words. Lipsy is also a form of behavioral dyslexia. The article was able to determine time accuracy functions for different children age groups. Dyslexia found to be linked with high noise. Learning-difficulty group showed fast processing than intelligence-matched group.
