Which mnemonic involves isolating a part of a word to form a mental image that aids memory?

The keyword method is a mnemonic technique that facilitates memory retention by linking new information to familiar words or images. In this method, a meaningful keyword related to the concept to be remembered is chosen. You then create a vivid mental image that connects the keyword with the new information. This method emphasizes the use of imagery and association, which enhances recall by creating a strong mental link between disparate pieces of information.

For example, if the goal is to remember the Spanish word "pescado" (meaning fish), one might use the keyword "pesky" to visualize a fish bothering someone. This blending of sound and mental imagery helps to solidify the memory in the learner's mind.

The other options represent different memory techniques. The semantic memory technique focuses on understanding and meaning rather than imagery. Visual imagery mnemonic is more general and doesn't necessarily isolate parts of words or use keywords as effectively as the keyword method. The image association technique might include similar principles but is not specifically about isolating a part of a word to form a mental image.
