Essay on Psychology: Critical Thinking

The three important points in the reading are: (1) infants know so little that they cant explore purposefully, (2) people hold information in three parts of the mental system for processing (sensory register, the short-term memory store, and the long-term memory store), and (3) the two main theories of language development are Nativist Perspective and the Interactionist perspective.

The Piaget's Sensorimotor Stage argues that at birth, infants know so little that they cant explore purposefully. It is divided into six sub-stages: reflective schemes, primary circular reactions, secondary circular reactions, coordination of secondary circular reactions, tertiary circular reactions, and mental representations. The reflective schemes sub-stage entails struggling onto a new encounter brought about by the babys own motor experience. Here, the reaction is circular since the infant attempts to re-do the event time and time again. The other four stages involve an infant engaging in intentional behaviours. In the mental representation sub-state, the infant starts to create innate manifestations of information which can be interpreted by the mind, mostly images and concepts.

People hold information in three parts of the mental system for processing: sensory register, the short-term memory store, and the long-term memory store. The information enters sensory register where the sights and sounds are directly represented and stored briefly. In the short-term memory store, people retain attended-to information briefly so that they can attend on it depending on their goals. The other part, the long-term memory is a permanent knowledge base where unlimited information can be stored ad retrieved any time for usage.

There are two main theories of language development: the Nativist Perspective and the Interactionist perspective. In the Nativist perspective, language gets into the structure of the brain focusing on grammar. It argues that the rules of sentence organisation are too complex to be understood by eve cognitively sophisticated young child. For this reason, the theory suggests that all young children have a language acquisition device (LAD). This is an internal system which has generally accepted grammar principles and rules in all languages. On the other hand, the Interactionist perspective emphasises interactions between inner capacities and environmental influences.

I would wish to agree with the argument from the passage that people hold information in three parts of mental system processing: sensory register, the short-term memory store, and the long-term memory store. For example, a person first acquires information through sights and sounds and this is enabled by the sensory register. Then, not all information gets to be stored by we filter and store the relevant information which is worked on to achieve our goals and this is enabled by the short-term memory store. From there, complete information is stored in large amount permanent in long-term memory store such that it can be retrieved anytime.
