Behaving optimaly in life

Social sciences and Psychologhy have brought us a number of interesting insights into human behaviour. In a recent stumbleupon session I discovered a collection of recent scientific journal research articles relating to various aspects of life. You can read the original article on psychologytoday, what follows is a subset of the "solutions" suggested by the research papers. For a more complete description I recommend the reader to check out the full articles and of course I wouldn't take this advice literaly but only something to ponder on :-).

1-How to break bad habits: J. Quinn, A. Pascoe, W. Wood, & D. Neal (2010) Can't control yourself? Monitor those bad habits. Personality and Social Psychology Bulletin, 36, 499-511

Focus on stopping the behavior before it starts (or, as psychologists tend to put it, you need to "inhibit" your bad behavior). According to research by Jeffrey Quinn and his colleagues, the most effective strategy for breaking a bad habit is vigilant monitoring - focusing your attention on the unwanted behavior to make sure you don't engage in it. In other words, thinking to yourself "Don't do it!" and watching out for slipups - the very opposite of distraction. If you stick with it, the use of this strategy can inhibit the behavior completely over time, and you can be free of your bad habit for good.

2-How to make everything seem easier: J. Ackerman, C. Nocera, and J. Bargh (2010) Incidental haptic sensations influence social judgments and decisions. Science, 328, 1712- 1715.

For instance, we associate smoothness and roughness with ease and difficulty, respectively, as in expressions like "smooth sailing," and "rough road ahead." In one study, people who completed a puzzle with pieces that had been covered in sandpaper later described an interaction between two other individuals as more difficult and awkward than those whose puzzles had been smooth. (Tip: Never try to buy a car or negotiate a raise while wearing a wool sweater. Consider satin underpants instead. Everything seems easy in satin underpants.)

3-How to manage your time better: M. Weick & A. Guinote (2010) How long will it take? Power biases time predictions. Journal of Experimental Social Psychology.

You can learn to more accurately predict how long something will take and become a better planner, if you stop and consider potential obstacles, along with two other factors: your own past experiences (i.e., how long did it take last time?), and all the steps or subcomponents that make up the task (i.e., factoring in the time you'll need for each part.)

4-How to be happier: J. Quoidbach, E. Dunn, K. Petrides, & M. Mikolajczak (2010) Money giveth, money taketh away: The dual effect of wealth on happiness. Psychological Science, 21, 759-763.

The basic idea is that when you have the money to eat at fancy restaurants every night and buy designer clothes from chic boutiques, those experiences diminish the enjoyment you get out of the simpler, more everyday pleasures, like the smell of a steak sizzling on your backyard grill, or the bargain you got on the sweet little sundress from Target. Create plans for how to inject more savoring into each day, and you will increase your happiness and well-being much more than (or even despite) your growing riches. And if you're riches aren't actually growing, then savoring is still a great way to truly appreciate what you do have.

5-How to have more willpower: M. Muraven (2010) Building self-control strength: Practicing self-control leads to improved self-control performance. Journal of Experimental Social Psychology, 46, 465-468.

New research by Mark Muraven shows that our capacity for self-control is surprisingly like a muscle that can be strengthened by regular exercise. Do you have a sweet tooth? Try giving up candy, even if weight-loss and cavity-prevention are not your goals. Hate exerting yourself physically? Go out and buy one of those handgrips you see the muscle men with at the gym - even if your goal is to pay your bills on time. In one study, after two weeks of sweets-abstinence and handgripping, Muraven found that participants had significantly improved on a difficult concentration task that required lots of self-control. Just by working your willpower muscle regularly, engaging in simple actions that require small amounts of self-control - like sitting up straight or making your bed each day - you can develop the self-control strength you'll need to tackle all of your goals.

6-How to feel more powerfull: D. Carney, A. Cuddy, and A. Yap (2010) Power posing: Brief nonverbal displays affect neuroendocrine levels and risk tolerance. Psychological Science, 21, 1363-1368.

In the animal kingdom, alphas signal their dominance through body movement and posture. Human beings are no different. The most powerful guy in the room is usually the one whose physical movements are most expansive - legs apart, leaning forward, arms spread wide while he gestures.  The nervous, powerless person holds himself very differently - he makes himself physically as small as possible: shoulders hunched, feet together, hands in his lap or arms wrapped protectively across his chest. We adopt these poses unconsciously, and they are perceived (also unconsciously) by others as indictors of our status. posing in "high power" positions not only created psychological and behavioral changes typically associated with powerful people, it created physiological changes characteristic of the powerful as well. High power posers felt more powerful, were more willing to take risks, and experienced significant increases in testosterone along with decreases in cortisol (the body's chemical response to stress.)

Search all text files by file's content

Finding a text-file, when one doesn't remember the file-name, or where one has stored it on the hard-drive can be a nightmare, especially since the Windows file-search fails. Powershell (udner Windows) comes to the rescue... all you have to do, is open up a Powershell console (in the newer versions it comes with the Windows OS, in older ones, you might need to download it).
  1. Make shure that in the command prompt of powershell you are within the drive you want to search (i.e. use cd and ..cd commands to get there, or type cd c: if you need to search the c drive.
  2. Get-ChildItem -Recurse -Include *.txt | Select-String "search string"
where search string is simply a piece of text that you know is in the contents of the file. For example in my case I type ANOVA, since I was looking for my notes on ANOVA tests. I think you can also use regex expressions, since powershell's Select-String cmd-let supports it, if I'm not mistaken.

Sports Informatics and Social Collaboration

After a long time, I felt it was about time for a quick update on my Blog. Things have been rather hectic in the last few months. After my torn-ligaments injury, I'm still recuperating, although I've been working for five months as a Research Associate in the field of Sports Informatics, for the computer science department at Loughborough University. This work involves grass-root research of various areas in computer science applications within sport. I am tasked with organising seminars, and a symposium, in addition to initial academic research. There are numerous potential applications, such as the use of image analysis in sports science, virtual reality uses in sports science, coaching applications within sports, or AI / intelligent systems in sports-data management / systems solutions in sports science.

The table below (Lames 2012 - Departmental Presentation) illustrates the two-way relationships between computer science and sports science subjects. Essentially any work at these subject intersections is known as the field of sports-informatics (see the IACSS association website, which is an umbrella association for this type of work).
My task in this research position is to establish research links with international and nation wide research centres, for the department. Loughborough has a strong tradition in sports science with international research excellence (see SSEHS or STI, for instance), and there is a lot of potential applications, for example in team player image analysis based tracking algorithms, or the use of Machine Learning in detection of team-play patterns within the computer science department. To me, an area of most interest are the application of communications / social-media technologies in sports. Recently some work looked at several sporting events, and analysed the social-media UGC (User Generated Content). What type of things people are talking about in regard to sporting events, how the fan-athlete relationship is changing from traditional media, and whether any revealing information is shared (Pegoraro 2010, Kassing and Sanderson 2010). I am especially curious whether Twitter and other social-media contributions may be revealing in relation to for example sport draft picks, line-ups and team-play / strategy changes (in other words, these are problems of talent detection and coaching). There is also more work to be done in investigating fan-athlete communications, such as predicting how likely an athlete / celebrity is to respond with a direct message to fans, identifying fans, and classifying them based on the dynamics of interactions, or correlating match tracking data with social media contributions, since this type of work has not seen much research.

I am also beginning a new RA position in the All-in-One project (funded by the EPSRC) at Leicester University. This is a project looking at single infrastructure provision, and its technological and scientific feasibility within a 100 years from now. This progress is motivated by climate change, cost reductions, and efficient use of utilities (see this working paper, for a basic introduction). My main task in this project is to work on a collaborative web-based (web 2.0 / social-media type) system that facilitates collaboration and sharing within an academic and also a wider citizen-science community. This is an interesting area of work, with various problems, such as: how to design a system that facilitates efficient social, web based collaboration of many individuals?; or how to attract and maintain an active user-base of contributors and collaborators on the web based system? There is some very interesting research work in this area that was done within the Climate CoLab project of MIT's Collective Intelligence Centre, and for example the CSCW conference, contains highly relevant research contributions that help answer the questions, above. My work, within the All-in-One project involves the deployment of a collaborative system / processes based on the evaluation of prior academic research. Some of my work within my PhD, such as the design of the Newsmental system, is relevant to this, and it will be interesting to put the entire concept of collective intelligence into practice, within a larger scale project, such as this one.

Simplicity in Web Apps

Dr. BJ Fogg from Stanford University does some interesting work in understanding Web 2.0 to human interactions... he even teaches a course at Stanford fully dedicated to Facebook :-)

Anyway, this is his model of simplicity as it relates to web apps, a very brief and rough intro, but maybe you'll find it useful - http://behaviormodel.org/ability.html

What I took away from it:

  • An ugly / simplistic but useful definition of SIMPLICITY: The minimally satisfying solution at the lowest cost.
  • Simplicity is contextual, i.e. it depends on the situation or person (not necessarily the product)
  • Simplicity is a function of your scarcest resource at that moment, where Fogg identifies these resources: Time, Money, Physical Effort, Brain Cycles, Social Deviance (i.e. going against socially acceptable norms), Non-Routine
Interesting stuff, he has many more resources on his web pages.
