Pritchard on pragmatics of knowledge ascriptions

I'm working on a review of Duncan Pritchard's book Epistemological Disjunctivism. I'll probably try out a few ideas here over the next couple of months. I want to start out by focusing on something from near the end of the book—§8 of Part III. Here, Duncan is trying to deal with what he considers to be a challenge to the particular form of neo-Moorean disjunctivist response to the skeptical paradox he's been developing. The salient element of the view is that, contrary to skeptical intuitions, one does typically know that e.g. one is related in the normal way to the world, rather than being a brain in a vat. This, even though one lacks the ability to discriminate perceptually between being related in the normal way to the world and being a brain in a vat.

The challenge Duncan considers in this section is that Moorean assertions like "I know I'm not a brain in a vat" seem conversationally inappropriate. As he puts it earlier in the book ...

We are Walking Rocks: Friends of the Pleistocene Explore the Geologic Now

Geopoetry Smudge Studio

In The Life and Death of Buildings: On Photography and Time Joel Smith writes:

Imagine making a picture using film so insensitive to light – so slow, in photographic parlance – that to burn an image onto it required an exposure of twenty-five centuries. Geologically speaking, the blink of an eye. The picture from that negative would reveal a world made of stone, and stone only. It would be a world where plants and people, seasons and civilizations, had come and gone, quite untouched, and unbothered, by mankind. And yet, here it is, a world, unmistakably shaped by human hands.

Perhaps one of humanity’s greatest weaknesses is that our power of imagination tends to be dwarfed by our power of transformation. Twenty-five centuries ago, Rome was little more than a small town; Confucius had just resigned from his government post; Olmec society had slid into decline; and none of the languages we speak today had yet evolved. Entire civilizations rise and fall within the blink of a geologic eye – and whether as cause or consequence, we ...

Study: Fish Oil Prevents Brain Shrinkage and Cognitive Decline in Older Adults

Three more cases of Alzheimer’s disease will have been diagnosed by the time you finish reading this article. More than 5 million people have Alzheimer’s in the United States alone (44 million worldwide), and the rate of new diagnosis is about one patient every minute, with no cure on the horizon. Now a new study adds evidence to the argument that fish oil supplementation could be one of the best preventives we have against the disease--at least for people not at genetic risk of developing it.

Researchers from Rhode Island Hospital studied three groups of older adults, ages 55-90, using neuropsychological tests and brain magnetic resonance imaging (MRI) every six months. The group included 229 adults with no signs of the disease; 397 who were diagnosed with mild cognitive impairment; and 193 with Alzheimer’s. All participants were part of the Alzheimer’s Disease Neuroimaging Initiative (ADNI), which began in 2003 and ended in 2010.

Results showed that adults taking fish oil, who had not yet developed Alzheimer’s, experienced significantly less cognitive ...

Improve Your Learning and Memory.

Handwritten Notes Lead to Better Learning

In response to the trend to abolish teaching of cursive in schools, about a year ago I posted an article on what I thought were the developmental benefits of handwriting (http://www.psychologytoday.com/blog/memory-medic/201303/why-writing-hand-could-make-you-smarter). That post has generated over 230 comments.

Now there is evidence that handwriting of lecture notes, compared to typing on a laptop, improves learning by college students. Following up on prior studies that indicated relative ineffectiveness of taking notes by laptop, researchers Pam Meuller and Daniel Oppenheimer provide clear evidence that handwritten note-taking produces better learning in college students.

They reported three experiments that compared the efficacy of college students taking notes by handwriting or with a lap top. Those who used handwritten notes that they studied later scored significantly higher than students using laptops, including fleet typists who took vastly more copious notes. Handwriters took fewer notes overall with less verbatim recording. There are many possible explanations, beginning with the "less is more" idea in which too much information produces cognitive overload. Notably, when the typing ...

Transhumanist Science Fiction: The Most Important Genre The World Has Ever Seen? (An Interview with David Simpson)

 

David Simpson profile imageScience fiction has been part of creative literature for several centuries, with the genre having come into modern form in the early 19th century. Unbeknownst to the casual reader perhaps, the role of science fiction in society has changed to some extent over this period of time, with new styles, mediums and subgenres developing, each with differing goals and appeals.

Exploring possible future technologies and their implications is only one aspect of the science fiction genre, but in regards to this facet writer and futurist Dr. Thomas Lombardo has said that science fiction speaks to the total person about the future, believing that it resonates with all the fundamental dimensions of the human mind and human experience. While science fiction fans may immediately grasp this sentiment and concur, I think it begs the question: why, if it does indeed address human identity in a deep and holistic way, has the genre (in written form in particular) always been somewhat of a marginalized interest? I dont believe there is an easy answer to this question ...

Meet the mother and father of cognitive neuroscience | Mo Costandi

Independently and almost single-handedly, husband and wife Uta and Chris Frith have transformed the way we view autism and schizophrenia.

Chris Frith sits at the kitchen table in his northwest London home, cutting slices of smoked salmon into irregularly-shaped pieces and then placing them in a meticulous tiling pattern onto pieces of buttered brown bread. It is, according to his wife Uta, the kind of obsessive, repetitive behaviour that is characteristic of children with autism.

There are people with perfectly normal personality variants who behave in an autistic-like way, says Uta, hovering behind him as she prepares a pot of tea. There was a time when autism was under-diagnosed and we wanted to raise awareness of it. Now, it has gone the other way these people are diagnosing themselves, and Im worried about over-extension of the diagnosis.

A torrent of accidental poems

CC Licensed photo by Flickr user Jonathan Reyes. Click for source.Neurology journal Neurocase has an interesting study of a women who started compulsively writing poetry after having brief epileptic amnesia treated with the anti-seizure drug lamotrigine.

A 76-year-old woman reported having a poor memory and short periods of disorientation and was eventually diagnosed with transient epileptic amnesia – brief recurrent seizures that lead to short periods where affected people can’t lay down new memories.

Several months after starting lamotrigine [a common and widely used anti-seizure drug], the patient suddenly began to write original verse. Whereas poetry had never previously been among her pastimes, she now produced copious short poems (around 10–15 each day) on quotidian topics such as housework or about the act of versifying itself and sometimes expressing her opinions or regret about past events. These poems often had a wistful or pessimistic nature but did not have a moral or religious focus. Her husband characterized them as “doggerel” because they were generally rhyming and often featured puns and other wordplay.

7 Rules That Keep My Life Simple

By Leo Babauta

I enjoy creating a few simple rules to live by that take away some of the overwhelming decision making we need to make every day.

Pre-think these decisions, formulate them into rules, and then just follow them, freeing your brain for more important decisions.

Why should we need to give so much thought to what we’ll wear and eat, how we’ll exercise and handle email, when these are things we do every single day?

So I’ve been crafting a few rules that keep my life simple, so I don’t need to think about the little things so much.

These rules change, depending on my life circumstances — what I’m working on, where I am, what else is going on, etc.

And I don’t get mad at myself if I need to bend a rule now and then … but try to stick with them as a general principle.

Children with autism learn imitative behavior from socially assistive robot

Humanoid robots could help autistic children practice imitation behavior, according to USC Viterbi School of Engineering researchers, based on a new study.

They examined how children with autism spectrum disorder (ASD) react to humanoid robots that provide “graded cueing” — an occupational therapy technique that shapes behavior by providing increasingly specific cues, or prompts, to help a person learn new or lost skills.

An imitation game

They divided a group of 12 high-functioning children with ASD into two groups, one experimental and one control. Each child then played an imitation game (“copycat”) with a Nao robot that asked the child to imitate 25 different arm poses.

The Return of Radical Empiricism

z

“All our knowledge begins with the senses, proceeds then to the understanding, and ends with reason. There is nothing higher than reason.” So wrote Immanuel Kant in his Critique of Pure Reason, one of the most influential philosophy books of all time. Kant is also the philosopher credited for finally overcoming the opposition between empiricism and rationalism in epistemology, as he realized that neither position, by itself, is sufficient to account for human knowledge.Kant was notoriously awoken from what he termed his “dogmatic slumber” [1] by reading David Hume, who had written in his Enquiry Concerning Human Understanding:“All the objects of human reason or enquiry may naturally be divided into two kinds, to wit, Relations of Ideas, and Matters of fact. Of the first kind are the sciences of Geometry, Algebra, and Arithmetic … [which are] discoverable by the mere operation of thought … Matters of fact, which are the second object of human reason, are not ascertained in the same manner; nor is our evidence of their truth, however great, of a like nature ...

Continuing our series on co-veillance, sousveillance and general citizen empowerment, on our streets... last time we discussed our right and ability to use new instrumentalities to expand our ability to view, record and hold others accountable, with the cameras in our pockets.

Now -- the other side of this accountability equation. 

Some ideas seem far-out "scifi"... until suddenly they become mainstream.  In the wake of the recent Ferguson, Missouri riots, a petition asking for a "Mike Brown Law" that would require all state, county, and local police to wear cameras. has achieved almost 150,000 signatures. Last August, a federal judge called for the NYPD to wear such cameras when she ruled that the department's stop-and-frisk policy violated people's constitutional rights. But as A.J.

Improving memory with transcranial magnetic stimulation

Using repetitive transcranial magnetic stimulation (rTMS) to indirectly stimulate the hippocampus (credit: Northwestern University Feinberg School of Medicine)

Northwestern Medicine researchers have discovered that using high-frequency repetitive transcranial magnetic stimulation (rTMS) to indirectly stimulate the hippocampus portion of the brain (which is involved in forming memories) improves long-term memory.

The discovery opens up interesting new possibilities for treating memory impairments caused by conditions such as stroke, early-stage Alzheimer’s disease, traumatic brain injury, and cardiac arrest — along with the memory problems that occur in aging.

“We show for the first time that you can specifically change memory functions of the brain in adults without surgery or drugs, which have not proven effective,” said senior author Joel Voss, assistant professor of medical social sciences at Northwestern University Feinberg School of Medicine. “This noninvasive stimulation improves the ability to learn new things. It has tremendous potential for treating memory disorders.”

The study was published today (August 29) in Science.

The study is also the first to demonstrate that remembering events requires a collection of many brain regions ...

Citizen Power - Part I: using our cell cameras for safety and freedom

If you push long and hard enough for something that is logical and needed, a time may come when it finally happens! At which point – pretty often – you may have no idea whether your efforts made a difference. Perhaps other, influential people saw the same facts and drew similar, logical conclusions! Here is my own latest example:

“Qualcomm and other wireless companies have been working on a new cellular standard—a set of technical procedures that ensures devices can “talk” to one another—that will keep the lines open if the network fails. The Proximity Services, or so-called LTE Direct, standard will be approved by the end of the year.”

This technology, which would allow our pocket radios to pass along at-minimum basic text messages, on a peer-to-peer basis (P2P), even when the cell system is down, would seem to be the obvious backup mode that we all might rely upon, in emergencies. Indeed, failure of cell service badly exacerbated the tragedies of Hurricane Katrina and Tsunami Fukushima. I have been hectoring folks about this ...

Posthuman Life: Philosophy at the Edge of the Human (new book)

Screen Shot 2014-08-29 at 9.55.11 AM

An exciting new book by h+ Magazine author and contributor, David Roden.

We imagine posthumans as humans made superhumanly intelligent or resilient by future advances in nanotechnology, biotechnology, information technology and cognitive science. Many argue that these enhanced people might live better lives; others fear that tinkering with our nature will undermine our sense of our own humanity. Whoever is right, it is assumed that our technological successor will be an upgraded or degraded version of us: Human 2.0.

Posthuman Life argues that the enhancement debate projects a human face onto an empty screen. We do not know what will happen and, not being posthuman, cannot anticipate how posthumans will assess the world. If a posthuman future will not necessarily be informed by our kind of subjectivity or morality the limits of our current knowledge must inform any ethical or political assessment of that future. Posthuman Life develops a critical metaphysics of posthuman succession and argues that only a truly speculative posthumanism can support an ethics that meets the challenge of the transformative potential ...

Deep Habits: Pursue Clarity Before Pursuing Results

hour-tally-600px

Shallow September

I track my deep work hours using a weekly tally, so I have a good sense of how my commitment to depth varies over time. A trend I’ve noticed is that my deep work rate hits a low point around this time of year.

The obvious explanation is that the start of the fall semester adds extra time constraints. But I don’t think that’s the whole story. My deep work tends to increase as the fall continues, even though my teaching commitments also increase during this period (i.e., once there are problem sets and exams to grade).

In thinking about this mystery I’ve begun to better understand a crucial but often ignored aspect of working deeply on important things: the necessity of clarity.

The bad teacher conspiracy

Any time I see an article about the evaluation system for teachers in New York State, I wince. People get it wrong so very often. Yesterday’s New York Times article written by Elizabeth Harris was even worse than usual.

First, her wording. She mentioned a severe drop in student reading and math proficiency rates statewide and attributed it to a change in the test to the Common Core, which she described as “more rigorous.”

The truth is closer to “students were tested on stuff that wasn’t in their curriculum.” And as you can imagine, if you are tested on stuff you didn’t learn, your score will go down (the Common Core has been plagued by a terrible roll-out, and the timing of this test is Exhibit A). Wording like this matters, because Harris is setting up her reader to attribute the falling scores to bad teachers.

Harris ends her piece with a reference to a teacher-tenure lawsuit: ‘In one of those cases, filed in Albany in July, court documents contrasted the high ...

A Touch to Fear: Chiropractic and the Newborn Baby

A significant part of my job as a pediatric hospitalist involves caring for newborns. It is arguably the best thing that I get to do as a physician, even if I do at times prefer the increased intellectual stimulation of the ill hospitalized child. While seeing newborns, I am almost always surrounded by happy and appreciative parents, grandparents and whoever else is invited to meet and greet the new arrival because the babies are almost always healthy. In fact, and not that I really care (sniff, sniff), the parents of newborns are with rare exception the only caregivers that ever thank me at discharge.

Unfortunately, sometimes I am called upon to assist babies that are having difficulty transitioning into the outside world for a variety of reasons. These reasons can range from the fairly minor and transient to the catastrophic.

I'm not sure what "another study" refers to in this case.

The mouseover title suggests a future research program in computational humanistic educational psychology:

I'd like to find a corpus of writing writing from children in a non-self-selected sample (e.g. handwritten letters to the president from everyone in the same teacher's 7th grade class every year)–and score the kids today versus the kids 20 years ago on various objective measures of writing quality. I've heard the idea that exposure to all this amateur peer practice is hurting us, but I'd bet on the generation that conducts the bulk of their social lives via the written word over the generation that occasionally wrote book reports and letters to grandma once a year, any day.

I suspect that children's letters to the president have always been heavily edited by adults. But modulo difficulties about selecting comparable samples across time, it might be possible to use the historical archive of ETS essays.

When we talk about the “file drawer,” let’s not assume that an experiment can easily be characterized as producing strong, mixed, or weak results

Neil Malhotra:

I thought you might be interested in our paper [the paper is by Annie Franco, Neil Malhotra, and Gabor Simonovits, and the link is to a news article by Jeffrey Mervis], forthcoming in Science, about publication bias in the social sciences given your interest and work on research transparency.

Basic summary: We examined studies conducted as part of the Time-sharing Experiments in the Social Science (TESS) program, where: (1) we have a known population of conducted studies (some published, some unpublished); and (2) all studies exceed a quality threshold as they go through peer review. We found that having null results made experiments 40 percentage points less likely to be published and 60 percentage points less likely to even be written up.
