To determine

To determine: The term used for generalizedmental image of an object, from the following options.

Definition

Impression

Concept

Mental picture

Solution:

Option (c) is correct.

Explanation

Introduction:

An abstract idea about anything is called concept. The concept can be based on an object, a theorem or a phenomenon.

Explanation:

Reason for the correct option:

To properly understand the things in nature, a rough idea or a plan is needed about that thing. Everything can’t just be understood by just seeing the object. This rough idea or a generalized mental image helps to understand the object or phenomenon properly and is called a concept.

Hence, option (c) is correct.

Reason for the incorrect options:

Option (a) is incorrect because definition is just a statement of an object or phenomenon. It doesn’t give a mental picture of the object. Hence, it is incorrect.

Option (b) is incorrect because the impression is a feeling or opinion about something or someone with a little information about it. So, it also doesn’t require our meet of having a rough image of the object. Hence, it is incorrect.

Option (d) is incorrect because a mental picture can be of any object in a rough way, like the image of a lion is a mental picture. But to gain information from the image, it should be specific and generalized. Hence, it is incorrect.

Hence, options (a), (b) and (d) are incorrect.

Conclusion:

Concept is the generalized image of an object in one’s mind by which he/she gains information about the object.
