All concrete objects generate images and the knowledge related to them is encoded both verbally as well as visually.

• This is known as dual coding hypothesis, originally proposed by the Paivio.
• According to this hypothesis, concrete nouns and information related to concrete objects are encoded and stored in the form of images while information related to abstract concepts assume a verbal and a descriptive code.
• e.g. If you are asked to describe a bird, the first thing that happens is that an image of a bird is generated and based on this image, you describe a bird. But on the other hand, the meanings of concepts link "truth” or “honesty" will not have such accompanying images.

So, any information which has been encoded verbally as well as in the form of images is recalled with greater ease.
