Community guidelines

Posts must:
1. be of academic interest to experts (i.e. someone already trained in cogsci or one of its related fields)
2. link directly to the original source material discussed (e.g. the actual research paper, not a blog or popular media discussion of it)
3. not be commercial (with rare exceptions, e.g. for companies' posts of actual research)
4. have comments enabled and not delete comments (summon a mod if there's a problem)

We've had a lot of posts lately that are of marginal quality, or are questions that a cogsci undergrad night have in their early years. Because of the breadth of the field, this is quite wide indeed, and dilutes the value of the community.

I'm adopting the same standard here that I did with the Computer Security & Lockpicking community[0]: for experts by experts, so that the signal to noise ratio is high for those of us who are in the field.

There are lots of other avenues for more newbie level discussion; this will not be one of them.

Current moderators are +Melissa Hall, +Michael Bernstein, and +Richard Law.


If you have any questions, issues with moderation, or would like to help moderate, please leave a comment on this post.

Sincerely,
Your friendly neighborhood community owner / meta-moderator

This is equally fascinating and worrying. Fascinating that there are these deviations that non-typicals exhibit, worrying that the idea that normality is health will simply enforce normal biases, rather than seek the truth using by combining a variety of biases.

As long as we are equally critical of normal cognition, I am not concerned, but I do not believe that this is true of the mental ‘health’ system.

An optimal level of procrastination to produce the best results.
 
How do creative people come up with great ideas? Organizational psychologist Adam Grant studies "originals": thinkers who dream up new ideas and take action to put them into the world. In this talk, learn three unexpected habits of originals — including embracing failure. "The greatest originals are the ones who fail the most, because they're the ones who try the most," Grant says. "You need a lot of bad ideas in order to get a few good ones."

This is a Demo App in the MatLab language which is meant for comparison of Bipropagation algorithm with Deep Neural Net from Google (AutoencoderDigitsExample).  
Find out for yourself which algorithm is faster and more accurate.

More info on the ResearchGate/Bojan Ploj, or 3rd chapter in the book Advance in machine learning research

+charles griffiths I know that this is a wiki quote. I dont know what is your message.

Bipropagation algorithm:
1st layer:
        weights selection, weights training

2nd layer:
        weights selection, weights training
...
last layer:
         weights selection, weights training

finaly
         stacking all the layers together,
         fine tuning

Yes. The weights are at first selected and after that they are also trained. Layer by Layer, from first one  to the last one. Only then are the layers stacked together and fine tuned. Selection is not based on data set, it is allway the same - eye matrix. Input values of each layer are very similar to the target values of the same layer - therefore learning is fast, accurate and reliable. Only few learning epochs is needed!

Algorithm is superior to the backpropagation and also to the autoencoder deep learning. Comparison with other was not done yet.

Consider to submit abstracts to our forthcoming Frontiers Research Topic "Owning a Body + Moving a Body = Me?"
The conscious experience of the bodily self is a cornerstone of human nature, which allows us to delineate the boundaries between the surrounding environment and us. A plethora of clinical and experimental investigations has clearly demonstrated that bodily self-consciousness draws on different neuro-cognitive mechanisms with distinct anatomo-functional underpinnings. Among these, the sense of body ownership (i.e., my body belongs to me), an...

The new SAMBA paper!!!
Here it is demonstrated that interpersonal interactions and empathic concerns to other people strongly affect subcortical defensive responses within peripersonal space. These findings add further hints to the debate on top down control over bottom up perceptual streams which defines the safety margins surrounding our body.

There's No Such Thing as Free Will
tl;dr:
“We need our beliefs to track what is true,” Harris told me. Illusions, no matter how well intentioned, will always hold us back. For example, we currently use the threat of imprisonment as a crude tool to persuade people not to do bad things. But if we instead accept that “human behavior arises from neurophysiology,” he argued, then we can better understand what is really causing people to do bad things despite this threat of punishment—and how to stop them. “We need,” Harris told me, “to know what are the levers we can pull as a society to encourage people to be the best version of themselves they can be.”

Recognizing this, we can dispassionately consider how to manage offenders in order to rehabilitate them, protect society, and reduce future offending. Harris thinks that, in time, “it might be possible to cure something like psychopathy,” but only if we accept that the brain, and not some airy-fairy free will, is the source of the deviancy.
Accepting this would also free us from hatred. Holding people responsible for their actions might sound like a keystone of civilized life, but we pay a high price for it: Blaming people makes us angry and vengeful, and that clouds our judgment.

“Hatred is toxic,” he told me, “and can destabilize individual lives and whole societies. Losing belief in free will undercuts the rationale for ever hating anyone.”

The big problem, in Harris’s view, is that people often confuse determinism with fatalism. Determinism is the belief that our decisions are part of an unbreakable chain of cause and effect. Fatalism, on the other hand, is the belief that our decisions don’t really matter, because whatever is destined to happen will happen.

Some scholars argue that we should think about freedom of choice in terms of our very real and sophisticated abilities to map out multiple potential responses to a particular situation… For Waller, it simply doesn’t matter that these processes are underpinned by a causal chain of firing neurons. In his view, free will and determinism are not the opposites they are often taken to be; they simply describe our behavior at different levels.

But we all may be better off believing in it anyway.

+Ryan Graham Yea, me too. It's shocking that we're still using a Medieval understanding of psychology as the underlying model upon which our injustice system is based. Somehow the entire legal system is based on fundamentalist Christian notions, and not on science. The separation of church and state should be applied to the legal system!

Another way to look at this is AlphaGo represents what general purpose hardware will be able to do seven years from now.

Hello all,
I am currently working on a 50+ page Literature review on processing fluency and truthiness. I am expecting to support a study I have designed for next semester examining processing fluency as the primary mechanism behind the production of the truthines phenomenon as described by Newman, Bernstein, Kantner, and Lindsay (2012).
I have the very few articles on truthiness currently available in the literature and am looking for as many strong/ prominent articles on processing fluency that I can gather to intellectually establish the link officialy. Seeing as none of the truthiness artcles outwardly states this as the underlying mechanism responsible I believe that both the literature reviewand the later empirical study an important addition to the literature.
If anyone could perhaps assist in any suggestions of important processing fluency papers please feel free to offer your suggestions. I am aiming for a min of 50 citations by the end so thought If i reached out to those better educated than myself I could broaden my range of articles.
Thankyou for any consideration you may give this, and I look forward to reading more in this comunity. I am so happy to have located this and the research being shared throughout it.

+Adriana Pérez The idea that cognitive biases persist despite awareness of the biases? We're not always the kind of rational we imagine ourselves to be, making up our minds subconsciously and then inventing a story about conscious deliberation.

It would be funny if only it were somebody else.

Interesting. Never heard of PPA before now. "[Joanne] Douglas has primary progressive aphasia (PPA)—a brain disorder that robs people of their language skills. Unlike other aphasias (language impairments) caused by trauma or stroke, PPA is degenerative: It gets worse, slowly and inexorably. But unlike other degenerative conditions, like Alzheimer’s dementia, it leaves most of a patient’s mental faculties untouched. People can still plan, reason, and multi-task. Their memories stay healthy and their personalities remain unchanged, at least at first.

But their blooming inability to write, read, speak, and comprehend can leave them locked inside their own heads, responsive but unable to respond, thoughtful but unable to share those thoughts. “It can be a truly devastating condition,” says Joseph Duffy from the Mayo Clinic College of Medicine. “It sucks our humanity, or what makes us uniquely human, from us.
[...]
It’s as if she has a daily quota of words—currently around half an hour of talking time, and less for writing. The disorder has progressed to the point when she can’t “have a significant conversation and produce a piece of high-quality writing on the same day.” And once the quota depletes, speech becomes hard and sentences start to look strange. Then, she lapses into silence and puts away any text, allowing herself to rebuild her cognitive resources.

So, Douglas carefully prioritizes when and how to use up her quota. “I’m always looking for quality rather than quantity, making the absolute best use of what I have, and not frittering away my very precious coterie of words,” she tells me. “I try to store up my reserves of language so they’re available for optimum use when I want to. And I spend most of my time alone fairly quietly.”
[...]
“My goal is always to be grateful for the abilities I have and use them to the best of what I can,” Douglas tells me. “The diagnosis makes all the difference to how I can approach the disorder.””
It's called primary progressive aphasia, and there's still a lot we don't know about it.

By comparing time travelling from self- and other-perspective, we found that temporal representation underlying one’s own projection shares many of the same characteristics of the temporal representation underlying another person’s projection

Comedy Theory
I am trying to understand how comedy works, and I have written an article about the subject:

https://medium.com/@rayalez/comedy-theory-fd142076657e

This is my first attempt to express the ideas I have about it. I'm not a neuroscientist, and I'm sure everything is much more complicated, and my theory can be totally incomplete and mistaken, but I think it has some useful epiphanies that explain a lot of things.

I am still working on it and trying to figure it out, and now I'm looking for some feedback/ideas, I really want to talk to some smart people about the subject.


Please let me know what you think. Any criticism/questions that you have, anything that is unclear or can be better explained, any thoughts/ideas would be very valuable to me!
I am working on a theory that would explain how comedy works, and turn the process of writing jokes into an understandab…
