Do Our Brains Determine Our Facebook Friend Count
Guest Post by Ian Fyfe, cheap Canada Goose originally posted on his own blog.
The canadian goose jacket amount of Facebook friends a person has correlates with the structure of brain regions involved in social interactions, according to Canada Goose Online research this week. But while this study made the top science news stories, looking a little closer reveals that it Canada Goose online has not delved deeply enough into our online behaviour to really tell us anything.
The researchers took brain scans of volunteers and measured the volumes of certain brain regions that have previously been buy canada goose jacket cheap linked with social behaviour in humans. These measurements were then compared with individuals’ answers to questions about their social life, including how many friends they have on social networking site Facebook.
They found that the volumes of some brain regions were bigger in individuals with more Facebook friends. In fact, on canada goose closer examination, there canada goose clearance is very little evidence that the correlation means anything at all.
One of the regions that correlated was the amygdala, a brain region involved primarily in emotion and emotional memory. Its volume has previously been shown to correlate with the size of an individual’s world’ social network, so the same result with Facebook is not groundbreaking; those with more friends might be expected to have more online friends. Two of these regions, canada goose clearance sale the right superior temporal sulcus (STS) and the left buy canada goose jacket middle temporal gyrus (MTG), have been previously linked to social behaviour, and the third, the entorhinal cortex, is involved in canada goose black friday sale memory, essential for keeping track of friends.
The amygdala (left image) is deep inside
the brain at the interface of emotional and The entorhinal
cortex (centre) overlays this on the inside, and feeds information into theThe function of the middle temporal cortex canada goose store (MTG) (central
image, red) is unknown, but it has been linked several functions including face
recognition and word meaning. The superior temporal sulcus (STS) is the tissue
in the groove along the top of the MTG this is thought to process biological
motion and where others are looking.
However, examining what we know about the functions of these areas challenges their relevance to online social networking. The STS processes biological motion and the direction of another’s gaze socially important functions, but not easily related to making friends remote friends via a screen https://www.officialcanadagoosesoutlet.ca . Moreover, the exact function of the MTG is unknown, and canada goose outlet store locations although it’s been implicated in Canada Goose Outlet face recognition, it has also been linked to understanding words while reading; a function more in line with web surfing than socialising. Finally, the entorhinal Canada Goose Coats On Sale cortex functions in all kinds of memory, so is not specific canada goose replica to social behaviour. In light of this, the relevance of the correlation diminishes considerably. On top of these dubious functional links, there are any number of confounding factors that cause variations in online social network sizes, as pointed out by Dr Heidi Johansen Berg in Canada Goose Parka her interview Canada Goose sale with the
While the study did find a correlation between social network and world’ network sizes, the average size of Facebook networks was more than three times the average number of phone book entries and over ten times greater than that of any other world’ measure, leaving plenty of room for the influence of other factors.
The actual significance of this study seems to hinge on a question that it didn’t even address: what canada goose outlet toronto factory does it actually mean to have more Facebook friends? It could mean that you are more sociable, as implicitly assumed in the study. But given that it indicates more time spent on the internet, it could also mean you are less canada goose coats on sale sociable. It may be that canada goose deals you moved schools several times when young and have added your entire year group from each school, or that you move jobs regularly. It could also mean you are more insecure or indiscriminate, more competitive or Canada Goose Jackets self important. It could even mean that you add who have a nice picture, or have the same very common name as you.
In short, there is little to say that the size of your online social network has anything to do with how sociable you are. This issue needs to be clarified before any links are made between brain function and online friendship groups homesite . Even then, uncertainty in brain region functions and confounding factors could still 2018 canada goose outlet outweigh anything else and render the results of this study meaningless. It may be research that attracts the masses to the science news, but canada goose coats it is a long way from actually telling us anything useful.
