Post 2: Self-Presentation

Review

In the third lecture, we mainly focused on the psychology of human beings. We first had an overview of human activity in social network, and then talked about the information processing procedure of human. It is very interesting to me that there are such many sub-categories of memory, and I am very curious that how our brain process memory and classify it. After that, we learnt about the hierarchy of cognition. I have never considered that human’ knowledge is a higher level than information processing, and I would like to consider it more from now on.

In the fourth lecture, we talked more about the human psychology in society, especially social networks. We learnt the social cognition theory, which is about how people learn from others, and then discussed collaboration in social network. Actually, from my various observations in life, I can feel people’s behavior is like what is stated in the social cognition theory, but it was the first time I came across the theory. It brought me to a brand new world of psychology!

Today’s Topic: Self-Presentation

The theories match my observations in life. Among these, I am most interested in self-presentation.

Self-presentation is the way that an individual represent him/herself, to match the impression that he/she want to leave to others. This concept was brought out by Erving Goffman (1922-1982) in his book The Presentation of Self in Everyday Life [1]. In his opinion, life is like a stage and people are like the actors on it. People judge how the others expect according to different situations and act to build their image.

Strategies

There are mainly 5 different ways (strategies) of self-presentation. 1) Self-promotion is trying to make others think you are competent or capable, which is usually used when one is proposing a job vacancy. 2) Ingratiation is trying to make others like you, for example, always praise or flatter others. 3) Intimidation is trying to make others think you are dangerous or dignified, and obey you, for example, a boss showing anger explicitly may make his colleagues work harder. 4) Exemplification is trying to let other respect you as a model, such as doing something moral apparently. 5) Supplication is trying to get others’ sympathy, such as stating yourself as helpless and needy. Besides, there are some other ways of self-presentation. One is called self-handicapping, which is stating there is an obstacle in front of you, then, if you succeed finally, it is because you overcome it; if you failed, it is because the obstacle.

Posting encouraging status - I think it is an example of exemplification


Posting “I’m sick” - an example of supplication, which is usually seen on Facebook

If you ask, which kind do I belong to in most situations? I think I am more of the kind of Ingratiation. When discussing with others, I seldom express different opinion towards others, even though they have a totally different view from me. Although people may apply different strategies in different situations, I seldom apply other strategies. Maybe it is because I have not interacted with others completely and have not come across enough situations!

Motivation

There are different reasons for self-presentation. Firstly, people want to leave good impression to others, and build good image of themselves, this is the basic motivation. Secondly, when one possesses negative emotion, self-presentation of a positive image can help to regulate it, by encouraging positive emotion and restrain negative emotion. Thirdly, due to need for belong, people need to show the membership of the group by presenting they are similar to each other. Fourthly, due to self-esteem, being respected by others or cared by others make people feel good, and self-presentation is one of its main sources.

Effect on Social Networking

On social networking, it is more easy to use self-presentation, especially when one is going to pretend differently from how he/she behaves normally. The reason is that the ways we communicate on social network is limited due to technology so far. For example, we mainly use text and picture on Facebook, twitter etc. Although some software allow us use different ways, such as video, people online can just see a part of us, which is easier to pretend, compared to a community in everyday life.

For example, when more and more lovers “show-off” what they do together on Facebook, men who are single are feeling lonely, because they still cannot find their Ms.right. There is even a Japanese guy who invented a way to pretend to have a lover [2]. See the picture below, he takes photo by himself but makes the photo look like taken by his girlfriend! Although most of the readers think it is useless to pretend to be in love, but it proves that pretending is very easy on social network.

Self-presentation can be seen as a kind of art and it is very hard to explain it fully in such a short paragraph. If you have any doubts, questions or comments, please leave it here and I am looking forward to it! =)

Post 1: Derived Social Recommendation

Review

In the first lecture, we had an overview about social media and social networking. From the lecture, I learnt about different characteristics of social networking, such as the user age. And I found that mobile apps are bringing more and more influence to people in daily life, especially in the aspect of social networking.

In the second lecture, we discussed about some kinds of social tasks and social media, and then go to social media marketing. I was surprised to found that there are already a large number of different social tasks in our life, and various companies and people are benefited by ideas provided by different individuals.

My Topic: Derived Social Recommendation

I am especially interested in the topic of derived social recommendations. Along with the rapid development of different social networking applications, techniques of derived social recommendations are applied more and more widely. Derived social recommendation is a system used to provide different recommendations to different individuals according to their personalized information.

Types and Applications

There are different types of derived social recommendations: collaborative filtering (including user-based filtering and item-based filtering) and content-based filtering. Let me show you some applications with these different types.

For user-based filtering, it groups similar users and find out what they like, and then recommends items that a lot of users like to another similar user. For content-based filtering, it groups similar items and recommends high correlated items to individuals. Such collaborative filtering is used on people who indicated their “targets”, for example, friends relations like Facebook, product purchase records like Taobao and Amazon, and music sharing platform like Douban FM, Last.fm. The advantage of such filtering is that it provides personalized choice to users, and you can find what you like easily by this system. The more items you indicated that you like, you will get more customized recommendations.

A part of recommendation page of Taobao, obviously using user-based filtering.

My friend recommendation interface of the app “LINE”, although I don’t know which collaborative filtering it is using, I still see some friends’ name (and I don’t have their numbers!) This is because I have a lot of common friends with them.

For content-based filtering, it relies more on an item called “tag cloud”. When you read a piece of blog or news article, for example, an article introducing Hong Kong food, you will see recommended articles about Hong Kong food too. This is because they have similar tags, and system tends to mark them as high correlated items. Of course, they are more applied on news sites, blog providers, since they are usually described in words. However, other contents can also apply this system as long as they can be described in words and categories! Its advantage is obviously that it doesn’t rely heavily on the “user-target” relationship, and you don’t need to indicate a lot of items you like in order to see a new one. But it may need more artificial work, such as tagging the items.

Drawbacks It Causes

Well, benefits it brings are well-known: it helps people discover new items they like easily. Therefore, I will talk more about its drawbacks.

1. Biased information

Do you know that your internet browser is filtering your information when you are unconscious? If you don't believe, just open Google and search a keyword, then ask a friend in another country to do so, you will find the results are different. The author Eli Pariser expresses his worry in his book The Filter Bubble: What the Internet is Hiding From You [1]. When the internet presents a biased world to you, your view will also be biased. For example, if you are politically radical, and you may find all radical post on Facebook, and conservative views will be hidden. This is somehow scary since you will be more and more radical, and may finally fail to judge fairly. In another way, does this process make people separated into different circles and communicate different ideas less and less?

2. Inappropriate tags

As I mentioned above, in content-based filtering, more artificial work may be needed such as tagging items. For simplicity purpose, many websites let users do the work of tagging by themselves, like blog providers will let the blog holders tag their own articles. Another example is Douban FM, which develops an application called Doublo and encourages users to tag music in a game. However, when users’ goal is to achieve more coincidence tags, they may just try words randomly, regardless of whether the word can represent that piece of music. Hence, we can see that, due to various reasons, users may tag items inappropriately. When an item is tagged inappropriately, it may encounter difficulties in matching users and items.

Description about Doublo

OK, I will end my topic here. Thank you for reading this piece of article and all comments are welcomed! =)
