If there is is one thing I don't like doing, is playing game of any kind. It destroys mind of both old and young ones and also wastes their precious and irreversible time.
Nothing is bad and detrimental unless it becomes an addiction. Same is with games. Here the responsibility of the parents is very high. Let the kids enjoy but do not allow them to become slaves of any sort of addiction.
Traditional games have been developed in a way that in addition to provide fun, also meet some important survival-value skills such as proficiency in the ability to employ eye contact, teamwork, interpretation of body language, as well as developing vital cognitive skills like memory and reasoning.
In contrast, video gaming can dissociate fun from any of those survival skills and become an end in itself rather than being a means for thriving in the real world. Video gamers are likely to continue to play when reward is given only under certain circumstances, which leads to excessive gaming and addiction.
The studies have shown that there is a link between gaming and release of excessive levels of dopamine in the brain, a feature also observed in cases of addiction to drugs and gambling. However, this correlation does not allow us to conclude any causal link.
In addition to involving the internal mechanism of the brain, compulsion for video gaming also involves cognitive level of social relations too. Video games provide a strong sensory stimulation as well as the capacity for gamers to escape from their purposeless, directionless, complex and uncertain real world life where there are consequences for their actions and they may feel inadequate.
Instead the game world provides simplified world, clear goals, amplified feedback and suspended consequences and allow the gamers to be involved in the game world. The no-consequences world of the video games becomes meaningless. And in case of excessive gamers, spending time on meaningless activity will risk any significance they eventually attach to the activity and to themselves.
Experts believe that technology has the potential to modify human behavior and brain. Therefore, we need to ensure that technology is designed in a way to achieve desired outcomes instead of detrimental ones.
