Middle Childhood Stage of Development

  Elementary school children are mostly in the age range of seven to twelve years old. This stage is commonly referred to as middle childhood stage. If based on Freud's psychoanalytic thought, this stage is the fourth stage of psychosexual development called latency stage. On this stage, traumas from preceding stage, the Phallic Stage, cause sexual conflicts to be repressed and sexual urge to be rechanneled into schoolwork and vigorous play. The ego, or the rational component of personality, and the superego, the component that consists of one's internalized moral standard, continue to develop as the child gain's more problem-solving abilities at school and internalize social value.

     Meanwhile, Erikson's psychosocial Theory presents this stage in his Eight Life Crisis in which one needs to overcome. By the age of six to twelve years, children experience the crisis of industry versus inferiority. Children must master the importance of social interaction and academic skills to feel assured. Failure to acquire these important attributes leads to the feeling of inferiority. Significant social agents are teachers and peers.
Erikson labeled the elementary school years as "I am what I learn". This is the period for school children to learn everything they have to do, such as learning to play, sports, extra-curricular activities, academic competition all of which they learn from peers and classmates, as well as from the school itself. They are also anxious to demonstrate the skills mastered.
     In Piaget's Cognitive Development, middle childhood is the stage which he called Concrete-Operational Stage. By this period, children can think logically and systematically about concrete objects, events and experiences. They can now perform arithmetical operations and mentally reverse the outcome of physical actions and behavioral consequences. The acquisition of these and other cognitive operations permit the child to conserve, seriate and make transitive inferences. However, concrete operators still cannot think logically about hypothetical proposition that violates their conception of reality.
    On this stage, development continues to be rapid, although the changes that take place may not be as obvious and observable as those in the earlier periods. Physical growths has slowed and few inches yearly is no longer as dramatic as it was in infancy or toddlerhood. Now, the major changes are largely internal, having to do with the child's way of thinking and feeling.

Cognitive Model of Learning

     Information Processing Theory explains acquisition of knowledge in a step-by-step manner. Sometimes, this theory is said to be analogous to how a computer works. What is good about this theory is its being organized in presenting how information comes to our mind. It gives us a picture or a diagram about how we learn things and processes that take place inside our head.

The Three Primary Processes
I. Encoding. This when the information in our environment is being sensed, perceived or attended to.

II. Storage. After we encode the information, it is stored for either a short or long period of time depending on how we process or encode the said information.

III. Retrieval. The stored information is retrieved when needed in a certain task.

The Three Main Stages of Information Processing

1. Sensory Memory
          Human body perceives the environment through the senses. These sensations travel to the brain as electrical impulses or synapses. However, these electrical impulses or synapses must be translated in such a way that the brain can understand. This process is called transduction. Sensory Memory, the first main stage of information processing is affiliated with the transduction of energy.
In this stage, our mind holds the information for extremely brief period of time, since it receives a great amount of information more than it can hold or perceive. This is the reason why attention is very important on this stage. In order for the information to proceed to the next stage, that information must be attended to, or must be familiarized by the thinker. In addition, the duration is different among the senses, like auditory memory is more persistent than visual memory.

2. Short-Term Memory
          This memory is also called working memory because this refers to what we are thinking in a certain moment of time. This stage is created if we attend to an external information, a thought that popped in our head, or both.
The capacity of short term memory is said to be 7 plus-minus 2. This means that STM can hold 5 to 9 chunks or bits of information. The duration of the information while in the STM is dependent on how we organize or practice/repeat that information. Thus, organization and repetition, plus chunking or grouping, can help the information proceed to the next stage, that is the Long-Term Memory.

3. Long-Term Memory
          This is the final stage of memory wherein the information can be stored permanently until needed. Its capacity is unlimited and its duration is indefinite.


          Take note however that these stages are not like that of machines that once turned on, will do the process 1st step, 2nd step, 3rd step, so on and so forth. The processes are said to be controlled and regulated by an executive processing system, more popularly known as metacognition. Metacognition, in simpler terms, is "thinking about thinking"
