MC is best known for his writings about flow.

Wiki: In his seminal work, 'Flow: The Psychology of Optimal Experience', Csíkszentmihályi outlines his theory that people are most happy when they are in a state of flow-- a state of concentration or complete absorption with the activity at hand and the situation. The idea of flow is identical to the feeling of being in the zone or in the groove. The flow state is an optimal state of intrinsic motivation, where the person is fully immersed in what he or she is doing. This is a feeling everyone has at times, characterized by a feeling of great freedom, enjoyment, fulfillment, and skill--and during which temporal concerns (time, food, ego-self, etc.) are typically ignored.

Reverse graffiti

| No Comments

Reverse graffiti is form of street art that involves carving into the dirt and dust that surrounds us. Artists subtract from a surface in order to create a negative image within the positive, often quite dark layer of grime.

The National Republican Congressional Committee is running an ad in Minnesota that local officials suggest distorts the skin color of the Democratic candidate for the seat, Ashwin Madia. Basic visual evidence seems to back them up.

Madia, a son of East Indian immigrants and a marine veteran, is pictured in the spot with a darker face and long shadows cast upon it. The ad accuses him of wanted to raise taxes, but the superficial aspects are the ones that have jumped out to observers.

This is a really cute clip set to good music that shows how parents teach a little girl to put her toys away by reinforcing each link in a behavioral chain with M&Ms.

This clip is about Skinner and some of his work. It mentions his social engineering, his inventions, his work with operant conditioning, and his learning machines. There is some nice narrated stock footage.

Backwards Chaining

| No Comments

In this clip the rat is trained to put a marble in a ring, push a rod, then press a lever to receive reinforcement. There are 3 links in the behavioral chain. It is backwards chaning because the last link, the third (the one that is reinforced) is trained first. Then the second, pushing the rod, is added. And finally the first link, picking up and moving the marble, is added.

The Do the Right Thing Effect

| No Comments

In our lab we have developed a model that examines cross-racial identification and have linked it basic cognitive processes. The model makes clear predictions about how faces of famous individuals who are of other-races will be processed. This is a clip from a blog that Kim sent as it is relevant to our model.

I hesitated about posting this section as I have concerns about even copying and pasting something that has the "N" word in it. However, since the text comes directly from Eric Deggans and I presume it is a direct quote from a movie...well I decided to edit the quote anyway.

Ask the white person nearest you whether these ideas make any sense.
The Do the Right Thing effect - I named this for the moment in Spike Lee's legendary film where he confronts a racist pizzeria operator with the observation that the guy makes awful comments about black people but loves Prince, Eddie Murphy and Magic Johnson.

"It's different," John Turturro's Pino Frangione insists. "Magic, Eddie, Prince are not [ivylea]iggers...They're not really black. They're black but they're not really black. They're more than black. To me, it's different."

And that's a dynamic no one can measure. It's been my experience as the occasional object of racism that there are some folks who feel badly about the idea of black people, but those attitudes can change for specific black people they feel they know.

So there are probably some Democratic voters who don't see Obama as a typical black person, and don't transfer those negative, generic feelings onto him -- particularly because he doesn't fit the easy stereotypes, even of black politicians. And as long as Obama has been running for president, there are many voters who didn't really get to know him until he clinched the Democratic nomination in July.

It's something people of color face every day: you're a symbol to the world until you get famous enough that you're not.

But as strong and as clear as Biden was tonight I am not in anyway advocating taking a victory lap. Yes, Obama is six to eight points ahead in many polls and yes, McCain has chosen a radical religious right unqualified VP and yes, the economy is in bad shape because of exactly the kinds of policies of deregulation that McCain has prided himself on. But still, the corporatists own the media, and I'm sure as I'm writing this they are talking about how it was a victory for Palin because she didn't repeat the Couric interview debacle or because she didn't say that troops were on their way to Russia right now. No, this isn't over. Many Americans are still freaked out about gradients in skin tone and voter caging and fraud are very real threats. And fear and lies are always hard to combat no matter how disconnected from reality they are. The good news is, we've got a decent chance. But I can't shake the feeling our system is more messed up than we know and we could still lose this thing.

Face Blind Lab - Prosopagnosia

| No Comments

Prosopagnosia, also called face blindness, is an impairment in the recognition of faces. It is often accompanied by other types of recognition impairments (place recognition, car recognition, facial expression of emotion, etc.) though sometimes it appears to be restricted to facial identity. Not surprisingly, prosopagnosia can create serious social problems. Prosopagnosics often have difficulty recognizing family members, close friends, and even themselves. They often use alternative routes to recognition, but these routes are not as effective as recognition via the face.


Eyetracking Study - CrossRace

| No Comments
Equally attending but still not seeing : an eye-tracking study of change detection in own and other race faces. (2007)

The present study aimed to investigate whether the faster change detection in own race faces in a change blindness paradigm, reported by Humphreys, Hodsoll and Campbell (2005, Visual Cognition, 12, 249-262) and explained in terms of people's poorer ability to discriminate other race faces, may be explained by people's preferential attention towards own race faces. The study by Humphreys et al. was replicated using the same stimuli, while participants' eye movements were recorded. These revealed that there was no attentional bias towards own race faces (analysed in terms of fixation order, number and duration), but people still detected changes in own race faces faster than in other race faces. The current results therefore give further support for the original claim that people are less sensitive to changes made in other race faces, when own and other race faces are equally attended.
