Final answer:
The statement that most mnemonic techniques require little conscious effort is false, as mnemonics generally need a conscious effort to create and utilize effectively for long-term memory retention.
Step-by-step explanation:
The statement that most mnemonic techniques require little conscious effort is false. Mnemonic devices are memory aids utilized to encode, store, and retrieve information, often making use of acronyms, acrostics, and jingles. These strategies can be particularly useful for retaining information in long-term memory, such as the steps in a process or the order of planets in the solar system. However, despite the effectiveness of mnemonics in helping with memory retention, they usually require a conscious effort to create and remember, especially when initially learning the mnemonic.
Effortful processing is involved in the use of mnemonics, as opposed to automatic processing, which occurs with little or no conscious effort. It is critical to actively engage with the mnemonic device to make the information meaningful and thus improve retention. Kahneman's description of heuristics highlights that while some mental shortcuts are automated, others like mnemonic devices necessitate conscious attention and effort.
