How Culture Shapes Our Senses. Photo FLORENCE, Italy — WE think of our senses as hard-wired gateways to the world. Many years ago the social psychologist Daryl J. Bem described the knowledge we gain from our senses as “zero-order beliefs,” so taken for granted that we do not even notice them as beliefs. The sky is blue. The fan hums. Ice is cold. That’s the nature of reality, and it seems peculiar that different people with their senses intact would experience it subjectively.

Yet they do. Now they have some quantitative evidence to support the point. For example, it’s fairly common, in scientific literature, to find the view that “humans are astonishingly bad at odor identification and naming,” as a recent review of 30 years of experiments concluded. It turns out that the subjects of those 30 years of experiments were mostly English-speaking. The team also found that some of these differences could change over time.

Why do radiologists miss dancing gorillas? 15 February 2013Last updated at 21:10 ET By Lorna Stewart Health Check, BBC World Service There is something odd about this scan of a patient's lung. Have you spotted it yet? How about the dancing gorilla on the right? It is not an everyday finding for radiologists, who are skilled at searching scans for tiny anomalies with potentially life-threatening consequences. But in one study, more than three-quarters of specialist tumour spotters were caught out by the greatest anomaly of their career.

The out-of-place image was the brainchild of Dr Trafton Drew, a psychologist at Harvard medical school. "When I first saw radiologists searching through these images, they go through so fast and they detect these things that to me looked completely invisible and I just wondered how in the world are they doing this? " He was inspired by a classic experiment from the 1990s, in which observers of a basketball practice failed to see a man in a gorilla suit walk across the screen. Distractions.

About KosmosLF. Sense Perception - Tok - Mr. 0' Perception - The awareness of things through our five senses- sight, sound, touch, taste and smell... an active process...our experience of the world is affected not only by what is 'out there' (the data our senses collect), but also by the structure of our sense organs and our minds. Perception is really a two step process involving: Perception are the result of a psychological process that combines what our eyes see with what we already think, feel, know, want, and believe, and then uses this combination of sensory information and preexisting knowledge to construct our perception of reality.

'Silencing' is an illusion that happens when an object that is moving is also changing it's appearance. Normally we can immediately tell if an object becomes lighter or darker, if it changes colour, or if it changes shape. However a recent paper by Jordan Suchow and George Alvarez (Suchow and Alvarez, Motion Silences Awareness of Visual Change, Current Biology (2011), doi:10.1016/j.cub.2010.12.019) of Harvard University, published in January 2011, shows something quite extraordinary. They created a number of videos in which an array of dots change their appearance.

In one video, the dots keep changing their colour, in another, they keep changing their shape. Initially this is very easy to see. In fact, it is completely obvious what is happening. The pattern of dots starts rotating. For most people, when the dots start to rotate, they either completely stop changing colour, or they hardly change colour at all. The authors explore various hypotheses as to why our visual system is fooled. Optical Illusions - The Hidden Tiger. Test Your Awareness : Whodunnit?

Synesthesia's blended senses. If you ask Emma Anders about the number five, she'll tell you that it's red. She'll also tell you that five is a mischievous, self-centered brat — like a kid throwing a temper tantrum at a party. "Two is yellow, three is purple, four is an intense sky blue," says the 21-year old student at UC San Diego. "An eight is very noble and kind of held together, almost like a parent figure to five. Nine is a brown-haired guy, and he's pretty calm — but he's really into seven. " For most people, a number is simply an arithmetical value that represents a quantity. But for Anders, it is also a thing that has a particular color and an entire suite of personality traits. This is the world of synesthesia, a perceptual phenomenon in which one sense kindles sensation in another. Other synesthetes see colors when they hear music, taste words before they say them or feel textures on their fingertips when they discern the flavors of particular foods.

Published: January 9, 2005 WO Mondays ago, the scale of the Indian Ocean catastrophe was just emerging from the incomplete earlier reports (from a Times article the day before: a tidal wave had "killed more than 150 people in Sri Lanka"). By the 4:30 Page 1 meeting, picture editors had examined more than 900 images of devastation to find the one that would stretch across five columns and nearly half the depth of Tuesday's front page.

Into a million homes came a grieving mother crouched beside the lifeless bodies of tiny children [photo], and perhaps more horrifying, three pairs of feet extending from beneath a white sheet in an upper corner, suggesting the presence beyond the frame of row upon awful row of the tsunami's pitiless toll. Many readers and at least a few members of The Times's newsroom staff considered the picture exploitative, unduly graphic, and by its size and placement, inappropriately forced upon the paper's readers. But in every case, someone needs to choose them. [3] Brain Story: The Mind's Eye - Part. 1. Kate Fridkis: The Problem With Dove's Real Beauty Sketches Campaign. Don't get me wrong, I am a sucker for the message "seriously, though, you're beautiful.

" And I agree with the viral Dove Real Beauty Sketches clip, so many of us get distracted by all of our perceived flaws. We get caught up in criticizing our appearances and miss out on our own beauty. We are often more generous toward strangers than we are toward ourselves. I like that the Dove campaign is pointing all of this out. I hope it starts a bunch of conversations. And I hope that my reaction is interpreted as a continuation of the conversation, rather than nitpicking criticism. Because I really don't want to nitpick, I just want to point out some things I noticed as I was watching. In the clip, some lovely, thin, mostly white women who are all pretty young describe their appearances to a forensic artist, who sketches them without looking at them. Something felt a little off.

And there was the slight issue of the artist being a man. It's true, many (though definitely not all!) When Eyes Deceive - Eyewitness Testimony. BBC Nature - How whales and dolphins focus sound beams on prey. 22 March 2012Last updated at 07:47 By Victoria Gill Science reporter, BBC Nature The team worked with a trained false killer whale named Kina Many marine mammals live in a world shaped by sound - producing clicks to map their underwater environment out of echoes. Researchers in Hawaii have now discovered just how finely tuned this "echolocation" can be. The scientists found that toothed whales can focus their beam of sound - pinpointing a target with a narrow stream of clicks to study it in detail. Their findings are published in the Journal of Experimental Biology. Laura Kloepper, a PhD student at the University Hawaii, led the study. Kina came to the University of Hawaii's Hawaii Institute of Marine Biology when the US Navy closed its Hawaii laboratory.

"The Navy was reducing its animal inventory at that time," Ms Kloepper told BBC Nature. "She's a dream to work with; we think she's probably the best echolocator in the world. " Dr Nachtigall said that Kina was a "professional researcher". Recalibrate Your Reality.
