I remember a site where you load it up and it says something simple, like "I like tea". And then you click tea and it expands so it says "I like really good tea." And then you can click other words, over and over, until there's finally a whole paragraph.
Love the site. Can't remember where it is. Can anyone remember?

I have a project where I need to see inside a sealed cup to see water flow pattern. The water is hot. I was thinking of a fiber optic camera, but need some help. The idea would be to make this repeatable. So the top and bottom are punctured to push water through at brew time.
Any thoughts on device? Setup?

I was recently in an Emotional Intelligence course where the facilitator discussed the "Three Chair Experiment," where three people sat beside each other without saying a word for 10 minutes. The result was the experiment was that all three people would eventually take on the emotions of the "emotionally strongest" individual - ie if someone was really happy, the other two would end up being happy too, even without talking. Or if someone was really angry, the other two would end up also being angry after the 10 minutes. I thought it was really interesting so I googled it, but couldn't find any more information. Has anyone else heard about this experiment? Are there any sites or papers out there that provide more information about this?

I'm trying to find information about taxes and volunteer paid experimental (non-clinical) studies. I work in a lab, and one of our participants told us a week ago that if a study pays (the volunteer) over a certain amount, it gets taxed. Can anyone tell me if this is true and give me an official link? We're in Philadelphia, PA, USA. I can provide any other relevant information you need. Thanks!

[StatisticsFilter] I’m trying to understand the extent that the statics of a particular experiment can be evaluated and trying to relate that to a 95% confidence interval. The experiment is considered “a standard”, but I want to keep the discussion as “high level” as I can so that we focus on only the relevant details. Any help or pointers in the right direction are greatly appreciated. [more inside]

My dog Duffy is very smart and even though he's pretty old he learns new things fast, so I am doing an experiment with him and I am finding his failure to pick up the trigger puzzling. He discerns the most subtle cues from others when he's trying to decide what to do next, so I wonder how this isn't working. [more inside]

Several years ago a psychology experiment found that in emergency situations, the body seems to engage in fight/flight before the cortex determines that, say, a lion is running at us. Can anyone help me find that study? And, for extra points, any subsequent studies showing action coming before thought in other sorts of scenarios?

When I was in college, probably in 1995 or 96, I was shown two short videos as part of an experiment that a graduate student in linguistics was conducting and then asked to describe the events in each.
I was later told that the first video was from a well-known psychology experiment and was shown to subjects as a control. The experiment was about my reaction to the second video.
Ever since then I've been wondering about that first video. [more inside]

I remember doing a discussion activity/thought experiment in high school where we had to choose 6-8 people from a list (e.g. pregnant teen, scientist, priest, stay-at-home mom, doctor) to save in a nuclear apocalypse and justify our decision. There was a paper handout associated with the activity, and I'm pretty sure my teacher didn't write it himself, because I've talked to friends who've done the same thing in a different context (church groups, retreats, etc. ).
I'm looking for a link to a copy of this activity, or a place where I'd be able to find it.

Computer Coding: I'm trying to write an experiment in E-Prime
that uses a Visual Analog Scale to allow subjects to bid on items. Basically, this means they move a slider with their mouse over a bar, and the position on the bar represents how much they are willing to bid. The thing is, they need to know what value
the slider currently represents before they can actually bid, and I'm having problems getting the text to update with the cursor position. Now, if any of you out there are E-Prime gurus I could really use your help for this bit. I need to figure out how to update a textbox in a 'slide' object in the middle of a loop. [more inside]

Okay, here is my dilemma. I'm trying to get an experiment running in which I present a series of BMPs to my participants. After months of pain and suffering, I have finally tweaked a set of stimuli which work for me, so I'm swimming in around 3500 BMPs.
But, since I can only torture my participants for an hour, I can only ask them to go through about 1200 of these BMPs, so I need some way to quickly and easily generate a selection of random BMPs from my bigger collection. [more inside]

I'm a social psychologist looking for some advice about where to find a programmer to write what would basically be a very simple flash-type game. The game itself would require some simple user-interactiveness (e.g. selecting options), a fairly low level of graphics (maybe not stick figures, but nothing too artsy), and the ability to collect and store user data. Any suggestions? [more inside]
