Three thoughts for today:

One

Charles Watts, essay “The Meaning of Rationalism”, 1905, (in An Anthology of Atheism & Rationalism, Gordon Stein, pg 22)

“The Rationalist Press Association, in its Prospectus, defines Rationalism ‘as the mental attitude which unreservedly accepts the supremacy of reason and aims at establishing a system of philosophy and ethics verifiable by experience and independent of all arbitrary assumptions or authority.’”

Two

Charles Watts, essay “The Meaning of Rationalism”, 1905, (in An Anthology of Atheism & Rationalism, Gordon Stein, pg 25)

“We have outgrown the old mode of propaganda, and we recognize more than ever the influences of our environment. We are, in this particular, like trees: we expand and grow from within, but often the iron band of circumstances that surrounds us prevents our free growth and expansion. We, therefore, adopt the rational plan of imparting a knowledge of the facts of existence as revealed by science and philosophy, believing that, in proportion as truth is recognised and accepted, error will disappear. Rationalism is bound by no ancient creeds, hampered by no alleged sacred books, nor marred by dread of punishment in some other world for entertaining unpopular opinions in this. Our desire, as Rationalists, is to urge a sound motive for conduct, which is that “the welfare of the people is the supreme law,” to obtain freedom for all in matters of opinion, to promote ethical culture irrespective of theological teachings, and to foster friendly co-operation in spite of divergency of thought.”

Three

Annie Besant, essay “Why I Do Not Believe In God” , 1887 (in An Anthology of Atheism & Rationalism, Gordon Stein, pg 30)

“…Truth, is a thing to be shouted from the housetops, not to be whispered over the walnuts and wine after the ladies have left; for only by plain and honest speech on this matter can liberty of thought be won. Each who speaks out makes easier speech for others, and none, however insignificant, has right of silence here. Nor is it unfair, I think that a minority should be challenged on its dissidency, and should be expected to state clearly and definitely the grounds of its disagreement with the majority.”

Are we out of context?

In the book Evolutionary Medicine and Health: New Perspectives (2008), edited by Wenda Trevathan, E.O. Smith, and James KcKenna, there’s a chapter by Carol Worthman titled After Dark: The Evolutionary Ecology of Human Sleep.

Worthman takes a look at how well people’s current sleep patterns match up with our ecological and evolutionary history — the context in which human sleep evolved. Any species with a long history is affected by the long-term development of the species over time in particular environments. When the environment changes dramatically in a relatively short period of time, there’s a lag as the species’ development catches up, so to speak, adapting to the change in environment. For a while, there’s a mismatch between the species’ current state and its current context.

The motivating question of Worthman’s chapter is are we out of context?

Human sleep

No one actually knows exactly why organisms sleep. Researchers have shown it’s essential; they’ve determined that sleep disruption and deprivation often has negative effects; they’ve mapped out stages of sleep as characterized by patterns of physiological, behavioral, and cognitive activities. Sleep habits are fairly plastic. We have the capacity to have “sleep debts” and make that up later — but if sleep is so important, asks Worthman, why is that possible? What kinds of situations provoke sleep restriction? What roles do stress and stress physiology play in disrupted sleep? And, most importantly, how have our sleep habits and the conditions under which we sleep changed in modern times from the context in which we evolved?

Factors that Worthman addresses include

• - housing, beds, climate control
• - co-sleeping practices
• - material, social, and psychological contexts
• - macrosocial factors such as technology, labor, social structure

How and when a person sleeps is regulated by demands for wakefulness from the circadian system, and demands for rest and slumber. Worthman talks about the evolutionary roots and elements of human sleep ecology. She discusses how sleep settings have tended to be social across societies, even before longhouses and one-room log cabins. We didn’t evolve in an environment where we put oursleves in a room to “lie down and die” for the night. Rather, humans tended to live in groups and sleep in groups, with all manner of activity occurring throughout the night — were fires, noise, other people, conversations, nighttime pests, and more. These were, ecologically speaking, signs of safety and security — signs that it was okay to sleep and let our own vigilance mechanisms relax.

Now think about insomnia for a moment. In some instances, difficulties getting sleep in our current society may be related to how and where we now sleep. If we close ourselves off from noise, fire, other people (essentially, take ourselves out of an environment in which some of the vigilance is taken care of for us), our vigilance mechanisms go off, so to speak, and attention is focused on the kinds of things about which we should be vigilant.

In these kinds of group settings and active-nightlife contexts, was sleep interrupted? Sure. But rather than just losing sleep, people stayed awake for good reasons — useful activities, time and energy demands, threats to physical survival, and social challenges. People have adapted to defer sleep to these kinds of activities. An interesting point — one can recover from lost sleep in far less time than the original deficit. An example Worthman gives is that tem days sleep deprivation can be recovered in one or three eight-hour nights.

A question Worthman asks is just how atypical our sleep patterns are, and whether these patterns are giving us problems we wouldn’t otherwise have.

How much do you sleep?

The biggest thing I got out of her article was this: Bedtimes are fluid. In the US, we seem to have the idea that to sleep properly, we have to be dead to the world for a solid chuck of eight hours. But sleep’s more fluid than that, and sleep isn’t just the time during which you’re dead to the world. We probably underestimate the time that we actually spend sleeping, and we probably make a bigger deal than is actually necessary about getting the recommended eight hours.

Take a look at other cultures — in some, people sleep for five or six hours and night, and maybe have a two-hour nap in the afternoon. Sleep doesn’t have to just be in one chunk. Punctuated sleep is fine. Napping is fine. Some college students seem to have figured this one out already.

Essentially, Worthman argues, we should worry about our sleep a little bit less.

Interested in more of the details?

Worthman’s chapter is definitely worth a read. Pun intended.

Gender, scientists, and reductionism: Why Vassar is special

This fall, for the first time in four years, I’m not returning to Vassar. What better time to muse on the college’s specialness?

Over the summer, a couple divisions became more apparent to me than they had been previously:

1. Gender in technology fields – I worked in a lab at NASA Goddard of fifty-some interns/apprentices with a large number of mentors who dropped in on a regular basis. I was the only female on my project; I generally worked in a room with fifteen guys. Only one of the mentors I knew was female, and she was a professor from a collaborating university, not from NASA.

   I should emphasize that the difference I’m focusing on here is not in treatment but in sheer numbers. Why is it that fewer women end up in technology fields? The fact that so many prominent organizations focus on promoting women in technology — including WIT, the Women in Technology project, NCWIT, and of course the Grace Hopper Celebration, which I attended last year — suggests there’s a problem. It’s at the point where it doesn’t even feel weird to be the only female in the room. Is there something wrong with that?

2. Science vs engineering – I mentioned this recently. There is a clear division between those who have been trained as scientists and those trained as engineers. Yes, each have their own goals and purposes, but why isn’t there more crossover?
3. Reductionism vs dualism – As elaborated in one of the first essays I wrote here, I’m not a dualist. A prominent place to find dualisms is in many of the world’s fine religions. Some of the conversations I had with people this summer have accentuated just how different that point of view is from my own.

The fact that I noticed these differences now — not during a previous summer or semester — highlights just how special a place Vassar is, and how different being at an undergraduate liberal arts college is from being in the rest of the world.

My closest friends at Vassar were also non-dualists; Vassar’s mix of genders is unique enough to begin with that the ratio in technology-related majors continues to be unique; Vassar lacks an engineering department and is generally full of scientists.

The rest of the world has different ratios of people and mixes of beliefs. I’m finding it fascinating to explore.

Questions vs answers

Recently, I had a discussion with a friend about the key difference between science and engineering.

As a computer engineer, my friend found that the more advanced his coursework got and the more he learned about electronics, circuits, and microprocessors, the better he understood the subjects as a whole.

Which shouldn’t be too surprising. That’s the point of a college engineering degree: learn how stuff works and how to make stuff work.

But me, I find that as I learn more about brains and minds, filled with complex interactions between neurons, glial cells, neurotransmitters, and hormones, the picture gets steadily more complicated. The universe is one big dynamic system, full of chaotic pieces, and I keep finding more questions. The more I learn, the less I know.

That’s the scientist’s perspective on the world: more knowledge means more questions. More astonishment, more confusion.

(This is not a novel pronouncement, merely a recent observation supporting previously suggested differences between the two disciplines.)

One identity?

I ran across the following quote from Mark Zuckerberg the other day — not for the first time — but this time my initial response, instead of being some disgruntled mumbling about Facebook’s privacy settings, was how Western.

“You have one identity. The days of you having a different image for your work friends or co-workers and for the other people you know are probably coming to an end pretty quickly… Having two identities for yourself is an example of a lack of integrity.” –Mark Zuckerberg

Why Western?

Geography, ecology, philosophy

Last semester, I read a book called The Geography of Thought: How Asians and Westerners Think Differently…and Why by Richard Nisbett. As you may infer from the book’s title, Nisbett talks about all kinds of differences in Western versus East Asian cultures and why those differences exist — and I mean all kinds. It’s a broad book. I’m going to give you the flavor:

Nisbett starts by outlining differences in philosophy. Greek philosophy took as a fundamental principle that matter divides into discrete objects. The Greeks drew a line between the internal and external, essentially inventing nature. Perhaps this was a result of their culture of debate, which relies on the notion that two minds can have different representations of the world and that the world has its own nature independent from both minds. Western cultures grew out of Greek philosophy. Since boundaries between any object and its surroundings were built in, people were discrete. Westerners emphasize individualism. The focus on objects and individuals may have led to many of dualisms we have encountered this semester.

Ancient Chinese philosophy, on the other hand, bespoke a constantly changing world, full of contradictions and moving in endless cycles. Harmony and holism were emphasized: there was a mutual influence of everything on everything else. Chinese has no abstractness, either; no “whiteness” without a thing that is white – the white of a swam, the white of the snow. People defined themselves in relation to others, interdependent rather than independent; the goal was The Way rather than truth or knowledge.

Some of these differences may have arisen in part from the ecology in which the cultures developed. Greece was a maritime location where people of many customs and beliefs were encountered, a city-state where rational argument was king, and curiosity and knowledge were valued for their own sake. Occupations favored the autonomous individual – herding, hunting, trading, fishing. Intellectual rebels could move cities to retain the ability for free inquiry, and the clashing of so many customs may have led to the development of formal logic to help deal with the frequent contradiction of opinion. In contrast, the Chinese population by and large belongs to the same ethnic group. Rarely were people with different beliefs and customs encountered, and because many people were farmers who depended on joint irrigation, agreed-upon norms and harmony with one’s neighbors were the goal. From Nisbett’s discussion, one might infer that it is the ecology that led to the development of these features of culture in the first place.

Assumptions about individualism – and language’s role

Nisbett also talks about assumptions. Westerners, he says, consider people to be individuals, assuming that everyone is in control of his/her own behavior, oriented toward goals, striving to be different from everyone else, and preferring justice to be blind. This is Zuckerberg’s assumption, in his above quote.

But not everyone thinks that way. Nisbett notes that East Asians tend to be more concerned with coordinated action and group goals, fitting in, and negotiating a “middle way” that will satisfy particular disagreeing parties. In Confucian philosophies, man cannot exist alone. This has interesting implications for how people understand themselves and how a self-concept is developed! East Asians tend to think that people are defined by their relationships to other people. This is reflected in their languages: Chinese has no word for “individualism” and Japanese has many “I” words, using different words to refer to the self in relation to parents, friends, or professors. East Asians, when describing themselves, refer to their social roles and find it difficult to not specify situations and contexts. Westerners explain personality traits, role categories, and activities – none of which are solely dependent on context.

What I wondered, while reading, was this: How does cultural emphasis on individualism versus collectivism change a person’s concept of self? Fivush & Nelson (PDF) (2004) suggested that autobiographical memory and a concept of self are partially developed through an awareness of self versus other. Wang & Ross (2007) proposed that language is very important to autobiographical memory, and Ratcliffe (2007) suggested that a person might learn to distinguish the self as an individual through interactions with others – but Ratcliffe is a Westerner! Do Westerners build up a concept of self in a different way than East Asians? Does the fact that people who speak certain East Asian languages have few if any explicit ways to refer to individualism or to an “I” without reference to other people influence them to conceive of themselves in a more relational, collectivist way? This points to a deeper question: How much do people’s languages impact their thoughts, conceptions, beliefs, and perceptions? Nisbett presented examples of how language might change how we think about the world around us. E.g., Westerners tend to learn nouns faster – nouns are objects, inert, and tend to be emphasized more in parent-child conversations. Verbs, which are reactive and about relationships, are more salient in East Asian languages. The properties of the language and how the language is used help drive the object versus relation and individual versus collective dichotomies we see across cultures. Again, I see the same paradoxical question: which came first, the language, or the concepts? How and why did these language differences originally evolve?

An interesting question here, with regards to the role of language priming for certain ways of thought, and differences in memory and recall, is this: Do people focus on things (such as objects, situations, and contexts) because they regard them as causally important, or do they regard them as casually important because they focus on them? Regardless of which statement is more true – and perhaps neither is – this statement highlights the role of interpretation. Nisbett discussed a study in which American students were primed to think either interdependently or independently. Students primed for independence rated individualist values as higher and collectivist values as lower; if primed for interdependence, the opposite was true. In an unprimed condition, American students rated individualist values higher while Hong Kong students rated collectivist values higher – but if primed for either case, all the students showed the aforementioned trend. This is interesting because Westerners, in their everyday lives, are constantly being primed as individuals, while East Asians are being primed with interdependence cues. Nisbett offers anecdotes of people who switched locations in the world and subsequently started behaving more independently or interdependently. Context matters!

Harmony vs agency

Nisbett also explains the ideas of erabi and awase. Erabi is active, agentic: the idea that people can freely manipulate their environments to suit their own purposes. Awase is harmonious, fitting in: the idea that people adjust themselves to their environments rather than trying to change them. The Western versus East Asian dichotomy is clear here. Are Westerners resistant to context-based models of the world, to theories such as Pentland’s (2007) that language may not do as much as we think, and to the general idea that individuals are subject to external forces and influences because of their erabi style? Perhaps this is also why the illusion of conscious will is so appealing – do Westerners have more of an obsession with free will than do East Asians? Nisbett notes later than East Asians report feeling less in control of their lives than do Westerners, but that they have less of an issue with this – instead of trying to control situations, they try to adjust them. East Asians also tend to be less susceptible to illusions of control than Westerners.

I am reminded of a quote from Nikos Kazantzakis: “Since we cannot change reality, let us change the eyes that see reality.” It puts me in mind of expectations. Peoples’ experiences set up their expectations about significance and meaning of future experiences – their culture influences what experiences they have. The same events don’t mean the same thing to everyone. In the context of this person’s experiences so far, different events may have been encountered more frequently, different behaviors may have been encouraged or discouraged, and different values emphasized. Nisbett (2003) discusses several studies that suggested East Asians are not as surprised by unexpected outcomes as are Westerners. This could be because they are more accepting of change to begin with – their world view anticipates that no situation will stay constant. Westerners, on the other hand, presume linearity of trends – the fact that they predict a trend to continue in its same direction could lead to their greater surprise when that prediction turns out to be false.

In sum: Agent, environment

In summary: Culture constantly surrounds us. It shapes how the people we interact with react to and interpret their environments, which in turn shape how they interact with us and what they emphasize in those interactions. It shapes and is shaped by language; language shapes and is shaped by our expectations and experiences. We have to keep in mind, however, that cultural differences are averages. Nisbett is careful to note this. Any individual person may not conform to the cultural norms. Although culture is a remarkably important context for a human, the development of a person in a culture is not quite so set as a cell being cultured in a petri dish. It is still the dynamic interactions between genes and an environment that develop a phenotype — an agent plus an environment. The environment, for a person, includes that person’s culture. A person’s past experiences with aspects of their culture – e.g., parent speaking styles, emphasis on objects versus relations, language – will influence that person’s present behavior. Oyama (2000a, 2000b) said we cannot attribute development solely to genes. Neither can development be attributed solely to culture, nor to the wider environment. It is through the interaction of all these contexts that we get functioning organisms.

A comprehensive Cognitive Science and Computer Science internship resource list

As my undergrad years draw to a close, I’ve compiled a list of internships and related opportunities for students in Cognitive Science and Computer Science. Most programs are also open to students in other engineering and technology fields and are not limited to undergraduate students!

Take a look! Pass along the page to anyone you know who may find it useful. Although deadlines for some summer 2011 programs have passed, many have March or April deadlines, and many of the semester or year-round programs have later deadlines.

Rock on

Are you familiar with perceptual control theory? If you aren’t, the basic idea is this: People are not rocks. As Philip Runkel puts it,

“Living creatures behave very differently from lifeless things. Unlike a rock, a human does not just sit until something bumps it.”
– Philip Runkel, “Casting Nets and Testing Specimens,” pg 75

The idea is, organisms and agents and people get a bunch of different sensory inputs. They have some internal standards for what they want that set of sensory inputs to be like — some desired state of the world. The difference between how they want the world to be and what the world is actually like drives what they do — what we see as behavior.

The reason this is appealing to me? Perceptual control theory (PCT) says we’re not just input-output machines. Behavior is goal-directed and purposeful.

It’s a useful theory if you want to figure out why people are doing what they do and how to avoid or mediate conflict. Everyone has internal standards that they’re trying to control. As Runkel says,

“[M]ost of us very often act as if we expect other people to behave like rocks. And when we act toward other people as if they were rocks or blankets or typewriters or teacups, we make unending trouble for ourselves. It is true that people do have some features in common with rocks and typewriters. There are, however, important differences between living and nonliving things that most of us overlook time and time again, and to our sorrow.”
– Philip Runkel, “People as Living Things; The Psychology of Perceptual Control,” pg 14

If you want to learn more, I’ve found you a nice list of articles, an informative Less Wrong post a friend linked me to, a comprehensive website, and Google.

And yes, talking about PCT really just was my excuse to share those lovely quotes from Runkel.
