The primary purpose of the passage is to

The primary purpose of the passage is to Some researchers contend that sleep plays no role in the consolidation of declarative memory (i.e., memory involving factual information). These researchers note that people with impairments in rapid eye movement (REM) continue to lead normal lives, and they argue that if sleep were crucial to memory, then these individuals would have apparent memory deficits. Yet the same researchers acknowledge that the cognitive capacities of these individuals have never been systematically examined, nor have they been the subject of studies of tasks on which performance reportedly depends on sleep. Even if such studies were done, they could only clarify our understanding of the role of REM sleep, not sleep in general. The researchers also claim that improvements of memory overnight can be explained by the mere passage of time, rather than attributed to sleep. But recent studies of memory performance after sleep – including one demonstrating that sleep stabilizes declarative memories from future interference caused by mental activity during wakefulness – make this claim unsustainable. Certainly there are memory-consolidation processes that occur across periods of wakefulness, some of which neither depend on nor are enhanced by sleep. But when sleep is compared with wakefulness and performance is better after sleep, then some benefit of sleep for memory must be acknowledged. present the evidence that supports a particular claim regarding REM sleep and memory, describe how various factors contribute to the effect of sleep on memory, argue against a particular position regarding sleep’s role in memory, summarize the most prevalent theory regarding sleep and memory, defend the importance of the consolidation of declarative memory

It's been 3 years. Surely it can't take that long for somebody to make a 5 minute explanation video? I paid $100+ for this. I can't recommend this software to other people if there are such obvious notions of slacking.

Wesley, I agree that we should add more video explanations to our forums, and I wish it were a higher priority.

At the same time, a Magoosh GRE subscription pays not just for the forums, but also for the video lessons and video explanations in the Premium platform. And for now, that's where Magoosh has been focusing it's efforts. We've actually just rolled out a number of new video lessons and answer explanations for our own questions.

That said, I'm definitely encouraging our writers and editors to update forum content too, as soon as they can. I'll continue to advocate for that, and I appreciate your feedback!

Hi! I've sent a note to our content editors about the issue. Unfortunately, we're a small team with quite a few projects, so it may take a while for a new video explanation to be uploaded. In the meantime, if you have any particular questions about the practice problem, feel free to post them here and we'd be happy to answer them :)
