How many Facebook Mends do you have? For some, the answer can be a signal of social success, and the numbers claimed can be enormous: Facebook permits 5,000 of them (though these might include products and companies as well as people). But Robin Dunbar, a psychologist at Oxford University, has long reckoned that claims of vast numbers of Facebook friends do not say much about actual human relationships.
Dr. Dunbar is the originator of Dunbar’s number, a rough measure of the number of stable relationships that individuals can maintain. He found a correlation between the average size of each species’s neocortex (a recently evolved part of the brain) and that of their social groups. 【F1】
Deducing the results to humans, he reckoned, meant they should have social circles—of close friends and relatives, and frequently seen acquaintances—of about 150 people.
Things have changed a bit since Neolithic and Roman times, though, and many wonder what effects modem technology might have on the size of such circles. 【F2】
Perhaps there is indeed a cognitive limit, imposed by the brain’s internal architecture, on how large a social structure can be maintained.
But there may also be another limit: time. Mamtaining 150 friendships face-to-face consumes a lot of that. Gathering together many times this number of connections online, though, is an easy thing.
Previous attempts to decide between these possibilities have tended to come down on the cognitive-limit side of the fence. 【F3】
But they have been criticized for looking at unrepresentative groups of people: students (inevitably), scientists and particularly heavy users of social networks.
The latest try, in which Dr. Dunbar carried on a survey organized by a biscuit-maker, has overcome that. It is the first national-scale, randomly sampled study to investigate the matter.
【F4】
The survey asked 2,000 people, chosen because they were regular social-network users, and a further 1,375 adults in full-time employment who might or might not have been such users, how many friends they had on Facebook.
The results showed, to no surprise whatsoever on the part of Dr. Dunbar, that the average number in the two groups were Dunbar-sized numbers: 155 and (when those who did not use Facebook at all were excluded) 187, respectively.
【F5】
These results, then, confirm that what constrains an individual’s number of friends is neurological.
Even though social networks could help people handle far more social interactions than Dunbar’s number describes, it seems the human brain simply cannot keep up.
【F1】
选项
答案
他认为,若将此研究结论对人类进行推断,它表示人类应当拥有150人左右的社交圈——包括密友、亲人以及经常碰面的熟人。
解析
①此句为主从复合句,主句宾语是由一个省略引导词that的从句充当。②主句的主语是动名词短语Deducing the results to humans。he reckoned可视作是插入语。③破折号之间的介词短语of close friends…acquaintances也可看作是插入语,作宾语social circles的后置定语,说明人类社交圈的范围,即包括什么人。句末的of about 150 people亦是social circles的后置定语,说明人类社交圈的人数。
