Errorless learning is particularly helpful for individuals with what type of memory impairment?

Errorless learning is a teaching strategy that focuses on preventing errors during the learning process. This technique is especially beneficial for individuals with memory impairments because it reduces the likelihood of practicing incorrect responses, which can reinforce errors rather than promote correct learning.

For individuals with severely impaired declarative memory, errorless learning is advantageous because these individuals struggle with recalling facts and episodes, which is essential for declarative memory. The structured approach of errorless learning allows them to learn information in a manner that does not rely on their ability to remember or retrieve that information actively. Instead, they are guided stepwise toward the correct response, which they can then learn more effectively.

When considering individuals with relatively unimpaired procedural memory, they may still benefit from errorless learning methods because procedural memory involves skills and tasks learned through repetition and practice. However, it's the combination of impairments in declarative memory that makes the strategy particularly effective, as these individuals may find it difficult to learn from their mistakes when attempting to recall or recognize information they should know.

Thus, the inclusion of both severely impaired declarative memory and relatively unimpaired procedural memory leads to the correct conclusion that errorless learning can be beneficial for individuals experiencing both conditions, making the chosen answer effective.
