Question

Sleep-dependent Consolidation of Important Information. Carefully review the article “Sleep Supports Selective Retention of Associative Memories Based on Relevance for Future Utilization” by van Dongen et al. (2012) and answer the following questions.

1a)   Hypothesis. What was the hypothesis being tested?

1b)   Methods. Provide a summary of the basic methodology (avoid too much detail here, and avoid cut-and-paste using the authors’ text).

1c)   Results. What were the most important results of the experiment (those findings highlighted by the authors in the Discussion Section of each article)?

1d)   Discussion. What conclusions do the authors make based on their findings?

Explanation / Answer

1a)   Hypothesis. What was the hypothesis being tested?

The hypothesis being tested is that whether the process of uniting memories is an active process, which occurs during a person being awake, or a passive process, depending on if the memories are to be utilised in the future.

1b)   Methods. Provide a summary of the basic methodology

The basic methodology used two sets of students, who, studied picture association locations, and instructed the students that there was going to be a retest of one of the sets. This retest was done after 14hours. During this delay, one set of students were allowed to sleep and the other set of students experienced a normal day with daily routine. After 14 hours, they were retested with both the sets of pictures, rather than one set.

1c)   Results. What were the most important results of the experiment (those findings highlighted by the authors in the Discussion Section of each article)?

It was observed as results that the memory retention was sleep dependent. This happened when the test takers were instructed that there was going to be a test next day. This memory retention was only associated with sleep delay and the subjects who were not subjected to sleep, had bad performance.

1d)   Discussion. What conclusions do the authors make based on their findings?

The conclusions made by the author is sleep dependence increased memory retention. Also, that these findings are in accordance with Diekelmann and colleagues', recent memories were prompted after the sleep wake cycle.
