Sleep and Memory
Sleep is an essential aspect of the life of every human being. Taking some time to have a
good sleep helps people not only to rest their bodies from exhaustion but also to improve their
memory by reducing the rate of forgetting. According to research, the number of hours a person
spends in sleep each night affects how well the mind stores information (Abel & Bäuml, 2013).
Abel and Bäuml authored an article covering the essence of sleep. The article’s title was “Sleep
Can Eliminate List-Method Directed Forgetting.” Their work was experimental and of
importance thus appearing in the peer-reviewed Journals of Experimental Psychology (Abel &
Bäuml, 2013).
Abel and Bauml did their experiment in 2013. According to their peer-reviewed article,
the research question was directed to finding out whether sleep reduces or amplifies list-method
directed forgetting (LMDF) (Abel & Bäuml, 2013). The two writers hypothesized their study by
stating that the people who sleep more forget less while those who sleep less forget more. This
hypothesis was meant to guide the experiment in finding out the necessity of sleep and its’
association with memory keeping. Memory and rest are apparently associated with each other.
People wherever all through the world rest unimportantly amid the night, wake up, and
encounter their dreary day of working Students, especially, stay up amid the night trusting that
the more they consider, the more they'll remember (Abel & Bäuml, 2013). This may be
substantial, yet rest is a fundamental key to advance to memory get. Understudies similarly may
pack information just before recollecting that it and assume that the sooner you know it, the
sooner you'll review it. This isn't legitimate in any capacity.
For memories to be expanded, sufficient rest is critical when learning is grabbed.
Looking into and reviewing the memory also depends upon limits that are maintained in the

prefrontal cortex (Abel & Bäuml, 2013). Cross-cortical association depends upon how much the
memory has been gotten to. Complete memories change given getting ready. This backing crosscortical association and empowers memories to be open. There is a various possible relationship
between EEG theta development in the midst of rest and memory mix.
Initially, the study comprised of 210 student participants. However, some factors were
considered thus eliminating 18 participants from the data analysis. These factors included sleep
disorders, alcohol intake between sessions and even taking a nap during the wake time (Abel &
Bäuml, 2013). After the elimination, the research remained with the data of 192 healthy students.
These participants had an average age of 22.5 years, and their age ranged from 18-30 years.
Additionally, the group included 76 males and 116 females with an equal distribution of
conditions (Abel & Bäuml, 2013).
A list of 16 concrete nouns was presented to the participants at the beginning of the
study. The experiment included a cue guiding the participants to either remember or forget
specific randomly selected terms. Moreover, there was a requirement for them to stay awake for
12 hours, sleep for 12 hours and have a short delay. The first half had a list that was followed by
a cue of remembering the items while the other half were given a prompt of forgetting the
details. After 12 hours, their memory performance was tested. The research design required the
participants to study the items and stay awake for 12 hours or asleep for 12 hours (Abel &
Bäuml, 2013). After that, the researchers assessed the effects of sleep against wake. They made a
comparison of the participants’ memory performance with regards to the 12-hour delay
conditions.
Statistical analysis for the experiment utilized ANOVA as the statistical tool. The
analysis made consideration of the cues, remember/forget, and time of day, am or pm. It showed

that there was a significant effect caused by the given cue, “F (1, 60) = 10.05, MSE = 408.37, p =
.002” (Abel & Bäuml, 2013). This revealed that participants recalled less when cued to forget
that when cued to remember, 31.6% vs. 47.7%. It was also found that there the condition and cue
had a significant interaction, “F (1, 124) = 4.23, MSE = 242.61, p = .042” (Abel & Bäuml,
2013).
This was an indication that the cue differently affected item remembrance; depending on
the state of the participants, either after sleep or after an awake period. Reliably, compared to the
cue to remember, the cue to forget “impaired item recall when the study group stayed awake –
28.5% vs. 41.4%), t (62) = 3.29, p = .002, d = 0.77” (Abel & Bäuml, 2013). However, this cue
did not affect remembrance if the “participants slept during the retention interval (48.0% vs.
49.6%), t (62) = 1” (Abel & Bäuml, 2013).
From the results gathered, it was clear that sleep played a significant role in LMDF. This
was evident since, in the 12-hour wake condition, participants presented consistent directed
forgetting whereas those subjected to 12-hour sleep did not. In fact, they were able to remember
the items equally well irrespective of the cue given to them. Therefore, the researchers concluded
that a successful LMDF depends a lot on whether the individuals stay awake or sleep after
encoding is done (Abel & Bäuml, 2013). Being awake after encoding may lead to successful
forgetting while sleeping after encryption may inhibit forgetting.
This study has adequately exhibited the relationship between energetic direct and human
understanding. Rest has furthermore related to specific subjective methodology, associated with
particular parts of the cerebrum. There is a critical relationship between REM rest and life
frameworks described to emotions (Abel & Bäuml, 2013). (In all psychological personality
issue, an association with a rest issue has been made.) It is at present apparent that this article

will pressure the relationship among rest, excited bearing, and mental mien issue. There is an
association between rest and the ability to change as per emotions.
