According to the lecturer of the Biophysics and Complexity course in the Biophysics Masters study program at the Bogor Agricultural University (IPB), Husin Alatas, this phenomenon is known as the Kappa Effect in the discipline of psychoanalysis.
The Kappa effect is when the length of the journey from one place to another feels different for some people, precisely when they go and return.
He continued, physically, if you take the same route, there is no difference in distance between going and returning. However, the travel time will be different if the speed when going and returning is different.
"Jika pulang dengan kecepatan lebih besar dibanding pergi, tentu waktu pulang lebih singkat dari pergi, dan sebaliknya," jelas Guru Besar bidang Fisika Teori ini kepada gobloker.com, Minggu (30/1/2022).
Let's assume the speed when going and returning remains the same, so the time it takes is physically the same.
HHowever, some people may still feel that the time to go home is faster.
This is more due to the way the brain works in perceiving time, especially regarding the duration of an activity.
According to his explanation, the Kappa Effect, which is related to the perception of the duration of activity by the brain, is very complex and involves many parts of the brain.
Not only that, under certain conditions, this perception may involve hormones.
Perception of time is based on information processed by the brain related to activities carried out during the trip.
"Stimulus from the outside is received in the form of what is seen, heard, and felt, and is also related to the accompanying environmental conditions," said Hus.
All of these things then have an impact on the brain's ability to perceive the duration of an activity.
In addition, a more familiar way home is also a factor.
Returning to the perception of a shorter time when returning home, it is reasonable to assume that there is little information about the destination when leaving and knowing information about that plreturning
