'''Magnification''' | {{#ev:gfycat|https://gfycat.com/DisloyalShockedJunebug|400x230|right|'''Magnification''' by '''[https://www.reddit.com/user/StingrayZ StingrayZ]''' - This is an animated example of the common [[psychedelic]] visual effect known as magnification. There is also a significant amount of [[visual drifting]] present within the animation.|frame}} | ||
'''Magnification''' (also known as '''macropsia''' or '''megalopsia'''<ref name="APADictionary-macropsia">{{cite journal|title=macropsia|journal=APA Dictionary of Psychology|url=https://dictionary.apa.org/macropsia | access-date=20 May 2022}}</ref>) is defined as the experience of distant details within one's visual field appearing closer and more "zoomed in" than they actually are due to both [[visual enhancements]] and [[hallucinatory states|hallucinatory effects]].<ref name="FischerHill1970">{{cite journal|last1=Fischer|first1=Roland|last2=Hill|first2=Richard|last3=Thatcher|first3=Karen|last4=Scheib|first4=James|title=Psilocybin-induced contraction of nearby visual space|journal=Agents and Actions|volume=1|issue=4|year=1970|pages=190–197|issn=0065-4299|doi=10.1007/BF01965761}}</ref> This can give the perception that one is seeing objects from greater distances than is usually possible within everyday life. | |||
At its lower levels, this can allow people to see objects | At its lower levels, this can allow people to see nearby objects (such as within reaching distance) as much closer than they really are, resulting in the perception that their visual capabilities have been enhanced.<ref name="FischerHill1970" /> At its higher levels, this can induce the perception of seeing distant objects as if they were right in front of the user despite their distance. These distances can range from several feet to hundreds of meters. Since this is most likely a physiological impossibility, it suggests that higher level magnification may actually be a seamless hallucinatory state in which the details of distant visual input are predictively simulated in a realistic and convincing manner. | ||
It's worth noting that this effect is considerably more likely to occur if a person spends extended periods of time staring at an object or scene within the distance. | |||
Magnification is often accompanied by other coinciding effects such as [[Visual acuity enhancement|visual acuity enhancement]] and [[pattern recognition enhancement]]. It is a rare effect that is most commonly induced under the influence of [[dosage#common|moderate]] [[dosage|dosages]] of [[psychedelic]] compounds, such as [[LSD]], [[psilocybin]], and [[mescaline]]. | |||
