Final answer:
According to the Atkinson-Shiffrin model of memory, there are three stages: sensory memory, short-term memory, and long-term memory. In the initial stage, the person tries to understand the task. In the second stage, the client becomes more fluid at the task, but may still be processing new aspects. In the final stage, tasks become more automatic and require a low degree of attention.
Step-by-step explanation:
The three-stage model you are referring to is the information processing model of memory, specifically the Atkinson-Shiffrin model. According to this model, there are three stages of memory: sensory memory, short-term memory, and long-term memory.
The first stage, sensory memory, is when the person is trying to understand the task. In this stage, information from the environment is briefly stored and processed through the senses. However, sensory memory can only hold a limited amount of information for a short duration before it decays or gets replaced.
The second stage, short-term memory, is the skill acquisition phase. It acts as a temporary holding place for information that is being actively processed. In this stage, the person is more fluid at the task but may still be processing new aspects of it. Short-term memory has a limited capacity and is susceptible to forgetting if not properly encoded into long-term memory.
The third stage, long-term memory, involves the storage and retrieval of information over a long period of time. At this stage, the person has acquired a high level of proficiency in the task and tasks become more automatic, requiring a low degree of attention. Strategies or techniques developed during the earlier stages of processing may become more automatic and intuitive.
