Social Sensitivity Hypothesis and Migration

by Sean Roberts in A Replicated Typo 2.0

Given findings that certain genetic variants will make a person more reliant on social contact under stress, the social sensitivity hypothesis proposes that certain genetic variants ‘fit’ better with certain social structures. In support of this idea, Way and Lieberman (2010) find a correlation between the prevalence of this variant and the level of collectivism (as opposed to individualism) in a society. This post looks at how this effect might interact with migration patterns.... Read more »

More on The Social Sensitivity Hypothesis

by Sean Roberts in A Replicated Typo 2.0

In a recent post, James wrote about the Social Sensitivity hypothesis.  Given findings that certain genetic variants will make a person more sensitive to social contact and more reliant on social contact under stress, it proposes that certain genetic variants ‘fit’ better with certain social structures.  In support of this idea, Way and Lieberman (2010) find . . . → Read More: More on The Social Sensitivity Hypothesis...

Review: Brain damage and ordering of panels in comic strips

by Neil Cohn in The Visual Linguist

I recently reviewed an older study of brain damaged individual's comprehension of final-panel jokes in comic strips. Here's another paper that explores brain damage and the ordering of panels in sequences.Participants were asked to arrange scrambled parts of a story into their accurate order, and the authors compared the abilities of numerous types of brain damaged patients. Participants ... Read more »

More on Phoneme Inventory Size and Demography

by Wintz in A Replicated Typo 2.0

On the basis of Sean’s comment, about using a regression to look at how phoneme inventory size improved as geographic spread was incorporated along with population size, I decided to look at the stats a bit more closely (original post is here). It’s fairly easy to perform multiple regression in R, which, in the case of . . . → Read More: More on Phoneme Inventory Size and Demography... Read more »

the original Whorf

by Chris in The Lousy Linguist

Guy Deutcher's NYT's article on how language affects thought continues to get buzz, as surely his book Through The Language Glass will when people read it (it was just released 3 days ago and is currently #234 on Amazon's book rank). One common reaction amongst bloggers is that Deutscher gives Whorf himself unfairly harsh treatment, and ultimately mis-represents Whorf's own opinions.For example, Kathryn Woolard, SLA President, says "Whorf’s own statements of his theory look little like the car........

the largest whorfian study EVER! (and why it matters)

by Chris in The Lousy Linguist

Let me take the ball Mark Liberman threw on Monday and run with it a bit. Liberman posted a thorough discussion of Fausey and Broditsky's neo-Whorfian English and Spanish speakers remember causal agents differently. Specifically, he invited readers to carefully examine the methodology of the experiments themselves, and not just focus on the conclusions. It turns out that a few years ago another set of neo-Whorfians, Jürgen Bohnemeyer and company, published a paper that addressed similar me........ Read more »

The new linguistic relativism: Guy Deutscher in the NYTimes

by gregdowney in Neuroanthropology

How does language affect thought and perception? It’s a question we’ve looked at here at Neuroanthropology.net on a number of occasions, but Prof. Guy Deutscher, offers a nice general survey of the current state of play in the research over at The New York Times in ‘Does Your Language Shape How You Think?’ Posts on [...]...

Phoneme Inventory Size and Demography

by Wintz in A Replicated Typo 2.0

It’s long since been established that demography drives evolutionary processes (see Hawks, 2008 for a good overview). Similar attempts are also being made to describe cultural (Shennan, 2000; Henrich, 2004; Richerson & Boyd, 2009) and linguistic (Nettle, 1999a; Wichmann & Homan, 2009; Vogt, 2009) processes by considering the effects of population size and other . . . → Read More: Phoneme Inventory Size and Demography...

Universal Patterns in Colour Terms are not Evidence for Innate Constraints

In a series of posts, I've been discussing constraints on the evolution of colour terms. Here, I discuss the role of drift and argue that universal patterns are not necessarily good evidence for innate constraints.... Read more »

Niche Construction in Colour Term Evolution

by Sean Roberts in A Replicated Typo 2.0

Language’s influence on perception can be regarded as a form of Niche Construction. The words we have for colours affects the way in which we co-operate with others to change the world. Therefore, not only does language become better at describing the environment, but the environment becomes better suited to being described by language.... Read more »

Neuroimaging of language: Why hasn't a clearer picture emerged?

by Greg Hickok in Talking Brains

This is the question raised in a paper by Evelina Fedorenko and Nancy Kanwisher published last year in Language and Linguistics Compass. The main point that they want to make is that language neuroimagers need to stop doing group studies and start doing functional localization in individual subjects, like the vision folks do. I don't disagree at all; e.g., see this post. In fact, we have used individual subject analyses in several of our papers (e.g., Okada & Hickok, 2006; Okada et al., in pr........ Read more »

Going Nuclear: Closing the Gap Between Radiation and Reason

by Matthew C. Nisbet in Age of Engagement

In a series of posts over at Scientific American's blog CrossCheck, John Horgan describes how several recent articles and books have prompted him to re-evaluate his views on nuclear energy. He specifically recommends Gynweth Craven's Power to Save the World, discusses John Mueller's Atomic Obsession, and describes how Wade Allison's Between Radiation and Reason has challenged his views about the risks of radiation exposure. Horgan's seminal End of Science partly inspired my research focus in gra........ Read more »

Evolution of Colour Terms: 8 Embodied Relationships

by Sean Roberts in A Replicated Typo 2.0

In a series of  posts, I’ve been discussing constraints on the evolution of colour terms.  In the last post, I discussed Perceptual Warping.  Here, a further adjustment to the assumptions about perceptual space is suggested.
The assumption that all perceptual spaces are the same may be unrealistic and may favour Universalism (see Levinson, 2000).  To begin with, . . . → Read More: Evolution of Colour Terms: 8 Embodied Relationships... Read more »

Conduction aphasia, speech repetition, and the left parietal lobe

by Greg Hickok in Talking Brains

Julius Fridriksson has been featured on this blog before and now his team has just published another noteworthy paper in J. Neuroscience. This paper sought to identify the neural correlate of repetition disorder in aphasia. Repetition deficits are characteristic of conduction aphasia although they are not exclusive to conduction aphasia nor is repetition the only deficit in conduction aphasia. Some historical background is useful, if for no other reason than most people get it wrong in one wa........ Read more »

Study: In Communicating about Nano and GMOs, Do the Frames or the Facts Matter?

by Matthew C. Nisbet in Age of Engagement

When attempting to communicate effectively with the public about a science-related debate, which is more important, framing the message or conveying science-based facts about the topic?  A forthcoming study (Word) at the Journal of Communication by Northwestern University researchers James Druckman and Toby Bolsen sheds new light on this long standing question.
As I will be highlighting at this blog, previous research consistently finds that the public typically form opinions in the absence........ Read more »

Memory and learning mechanisms are necessary to acquire colour categories (Komarova, Jameson & Narens, 2007).  Models have shown that individual learning alone does not lead to categorisations that are shared . . . → Read More: Evolution of Colour Terms: 4 Learning Constraints... Read more »
