An international group of scientists from Harvard, Oxford, Manchester, Sydney Universities and King's College London summed up the research on the impact of the Internet on cognitive functions and the human brain. Both temporary and stable changes in most areas of human intellectual activity have been identified. The influence of the Internet (including negative) on memory, attention, socially-oriented cognitive abilities and the general intellectual level of a person has been confirmed.

We publish the main provisions of the work.

The brain initially possesses neuroplasticity — the most important quality that allows it to change its own organization in the process of learning, solving new tasks, mastering a new environment by a person (4).

Thus, the collection of information on the Internet quickly causes people to become dependent on this tool when faced with any previously unknown problems.

  • the average person has about 150 "friendships" (which, however, varies greatly between people), and
  • "friendships" are divided into five hierarchical levels — "main partners", "intimate relationships", "best friends", "[close] friends" and "all friends";
  • in numerical terms, these levels are arranged with a scaling factor of "about 3" — the average value of the "volume" of the levels: 1.5, 5, 15, 50 and 150 people, respectively.

For better or worse, we are already conducting a massive experiment on the widespread use of the Internet by the world's population. In this regard, new studies are becoming increasingly important, which should provide more specific data (including for different ages, nationalities, social groups, etc.) for a more complete understanding of the impact of the Internet on us and our society.
