Final answer:
Qiang's recollection of words by their meaning rather than the exact terms illustrates the impact of encoding meaning, which is related to semantic encoding.
Step-by-step explanation:
When Qiang was asked to memorize a list of words and then later recalled those words as similar but different words, this exemplifies the impact of encoding meaning. This is because he remembered words such as 'boat' instead of 'ship' and 'teacher' instead of 'professor', which shows that he had understood the semantic content of the words but had not encoded the exact terms. This relates to semantic encoding, which involves encoding the meaning of a word rather than its visual or acoustic properties. People tend to remember information more effectively when it is encoded semantically, especially when using the self-reference effect, making the material personally meaningful.
