'''Memory enhancement''' is defined as an improvement in a person's ability to recall or retain memories.<ref name="MondadoriMöbius1996">{{cite journal|last1=Mondadori|first1=Cesare|last2=Möbius|first2=Hans-Jörg|last3=Borkowski|first3=Jürgen|title=The GABAB receptor antagonist CGP 36 742 and the nootropic oxiracetam facilitate the formation of long-term memory|journal=Behavioural Brain Research|volume=77|issue=1-2|year=1996|pages=223–225|issn=01664328|doi=10.1016/0166-4328(95)00222-7}}</ref><ref name="IlievaHook2015">{{cite journal|last1=Ilieva|first1=Irena P.|last2=Hook|first2=Cayce J.|last3=Farah|first3=Martha J.|title=Prescription Stimulants' Effects on Healthy Inhibitory Control, Working Memory, and Episodic Memory: A Meta-analysis|journal=Journal of Cognitive Neuroscience|volume=27|issue=6|year=2015|pages=1069–1089|issn=0898-929X|doi=10.1162/jocn_a_00776}}</ref><ref name="BorotaMurray2014">{{cite journal|last1=Borota|first1=Daniel|last2=Murray|first2=Elizabeth|last3=Keceli|first3=Gizem|last4=Chang|first4=Allen|last5=Watabe|first5=Joseph M|last6=Ly|first6=Maria|last7=Toscano|first7=John P|last8=Yassa|first8=Michael A|title=Post-study caffeine administration enhances memory consolidation in humans|journal=Nature Neuroscience|volume=17|issue=2|year=2014|pages=201–203|issn=1097-6256|doi=10.1038/nn.3623}}</ref><ref name="MorganStevens2010">{{cite journal|last1=Morgan|first1=Annette|last2=Stevens|first2=John|title=Does Bacopa monnieri Improve Memory Performance in Older Persons?

It can also help one retain new information that may then be more easily recalled once the person is no longer under the influence of the psychoactive substance.  
'''Enhancement of memory''' is an effect which allows for both better recollection and retention of short and long term memories.  


This effect can be described as a cognitive enhancement which amplifies and enhances both the ability to absorb and retain information and experiences in a level of clarity that exceeds normal recall abilities. This allows for a person to easily access stored memories and recall them vividly in a lossless manner, which can be expressed and interrelated with other stored memories more fluidly. This leads to the recollection and access of previously forgotten or repressed memories and the ability to vividly store new memories that are ascribed with a great amount of detail.  
Memory enhancement is often accompanied by other coinciding effects such as [[analysis enhancement]] and [[thought acceleration]]. It is most commonly induced under the influence of [[dosage#common|moderate]] [[dosage|dosages]] of [[stimulant]] and [[nootropic]] compounds, such as [[methylphenidate]],<ref name="MehtaOwen2000">{{cite journal|last1=Mehta|first1=Mitul A.|last2=Owen|first2=Adrian M.|last3=Sahakian|first3=Barbara J.|last4=Mavaddat|first4=Nahal|last5=Pickard|first5=John D.|last6=Robbins|first6=Trevor W.|title=Methylphenidate Enhances Working Memory by Modulating Discrete Frontal and Parietal Lobe Regions in the Human Brain|journal=The Journal of Neuroscience|volume=20|issue=6|year=2000|pages=RC65–RC65|issn=0270-6474|doi=10.1523/JNEUROSCI.20-06-j0004.2000}}</ref> [[caffeine]],<ref name="BorotaMurray2014" /> [[Noopept]],<ref>{{cite journal | vauthors=((Ostrovskaia, R.

This ability leads to a better system of organizing and labeling perceived content within the short and long term memories and stores it in a more structured, organized and easily accessible manner. In terms of the pharmacological aspect of this effect, while the enhancements on absorbing and retaining information and experience in the short term memory is something that generally occurs for the duration of the substance, the effects on long term memory recall can allow old and forgotten memories and information to seem vivid and new, while also allowing newly absorbed information to be retained for a longer amount of time without repeated exposure than normal.
====Types====
<onlyinclude>
Different substances can enhance different kinds of memory with some considerable overlap. Generally, there are three types:
* '''Long-term memory:''' A vast store of knowledge and a record of prior events.<ref name="Cowan2008">{{cite journal|last1=Cowan|first1=Nelson|title=Chapter 20 What are the differences between long-term, short-term, and working memory?|volume=169|year=2008|pages=323–338|issn=00796123|doi=10.1016/S0079-6123(07)00020-9}}</ref>
* '''Short-term memory:''' Faculties of the human mind that can hold a limited amount of information in a very accessible state temporarily.<ref name="Cowan2008" /><ref name="EngleTuholski1999">{{cite journal|last1=Engle|first1=Randall W.|last2=Tuholski|first2=Stephen W.|last3=Laughlin|first3=James E.|last4=Conway|first4=Andrew R.

* '''Working memory:'''  Information used to plan and carry out behavior. Not completely distinct from short-term memory, it's generally viewed as the combination of multiple components working together. Measures of working memory have been found to correlate with intellectual aptitudes (and especially fluid intelligence) better than measures of short-term memory and, in fact, possibly better than measures of any other particular psychological process. Both storage and processing have to be engaged concurrently to assess working memory capacity, which relates it to cognitive aptitude.<ref name="Cowan2008" /><ref name="EngleTuholski1999" /><ref name="DanemanMerikle1996" /><ref name="DanemanCarpenter1980">{{cite journal|last1=Daneman|first1=Meredyth|last2=Carpenter|first2=Patricia A.|title=Individual differences in working memory and reading|journal=Journal of Verbal Learning and Verbal Behavior|volume=19|issue=4|year=1980|pages=450–466|issn=00225371|doi=10.1016/S0022-5371(80)90312-6}}</ref><ref name="KyllonenChristal1990">{{cite journal|last1=Kyllonen|first1=Patrick C.|last2=Christal|first2=Raymond E.|title=Reasoning ability is (little more than) working-memory capacity?!|journal=Intelligence|volume=14|issue=4|year=1990|pages=389–433|issn=01602896|doi=10.1016/S0160-2896(05)80012-1}}</ref>
