Vote for your story of the year - psychology

It's round five of the Poll of the Year, where you vote in your favourite stories from this blog for 2009. This round - psychology. Here's a smattering of some of the (in my opinion) coolest, most surprising and, in some cases, most useful, stories of the year. Which do you rate?

• People who think they are more restrained are more likely to succumb to temptation
• Holding heavy objects makes us see things as more important
• Information overload? Heavy multimedia users are more easily distracted by irrelevant information
• Do lost people really go round in circles?
• Our moral thermostat - why being good can give people license to misbehave
• To predict what will make you happy, ask a stranger rather than guessing yourself
• Violent films and games delay people from helping others
• The peril of positive thinking - why positive messages hurt people with low self-esteem
