Verified step by step guidance

1. Understand the context of the problem: The question is asking about the cognitive process people use to determine the number of televisions in their house.
2. Identify the key terms: The options provided are 'mental image,' 'concept,' 'prototype,' and 'algorithm.' Each of these terms relates to different cognitive processes.
3. Define 'mental image': A mental image is a representation in a person's mind of the physical world outside that person. It is often used to visualize objects or scenarios.
4. Consider how people might use a mental image: When asked about the number of televisions, individuals might visualize their home and mentally 'walk through' it to count the televisions.
5. Evaluate the other options: A 'concept' is a general idea or understanding, a 'prototype' is an ideal example of a category, and an 'algorithm' is a step-by-step procedure for calculations. These are less likely to be used in this context compared to a mental image.
