Neuroaesthetics, Part 2: Fiction's Effects

Last week I posted a summary of Alexander Kafka's discussion, in the Chronicle of Higher Education, of Eric Kandel's newest book, The Age of Insight: The Quest to Understand the Unconscious in Art, Mind, and Brain, From Vienna 1900 to the Present (Random House).  In this new study Kandel synthesizes his interests in visual art and neuroscience, producing what Kafka judges to be an important text in the burgeoning field of neuroaesthetics. Not more than a week after I read Kafka's essay, I came across Annie Murphy Paul's short essay, "Your Brain on Fiction," in the New York Times' SundayReview section, and could see that she was in direct conversation with Kandel (and Kafka), and any number of other people talking about the relationship between art, the mind, consciousness and the illusion of "free will," and so many other related topics. Had my classes not already concluded I probably would have emailed this essay to all my students, because it in a concise and cogent fashion it walks through a number of fascinating points about what brain scientists are discovering concerning how fiction--and other non-documentary, narrative forms, including films--affects us.  As I like to say over and over, fiction--and art--is hardly frivolous, and as I feel I must point out over and over, the fictional works of a now deceased hack writer and philosopher and economist manquée have already profoundly and disastrously affected and constantly threatening to once again negative affect the lives of 310 million Americans, and potentially many more people around the globe. (The first person who posts the correct name of said fiction writer and at least one of said fiction writer's notorious and scarily popular books will receive a copy, sent by me, all postage paid, of either Nathanaël West's Miss Lonelyhearts and The Day of the Locust* or Allen Ginsberg's Howl, since I have several extra copies of both books and will gladly send them to you free of charge!) I'll only add that a number of the people I note online breezily ranting about slashing funding for the humanities and arts appear to be deeply influenced by this person's work and unaware of the profound resulting irony.

But back to Annie Murphy Paul's essay, which talks about how brain scans are demonstrating the profound effects of what happens when we "read a detailed description, an evocative metaphor or an emotional exchange between characters." Fictional narratives--and evocative metaphors, and other forms of figurative language occur in poetry, plays, creative nonfiction, and other literary forms--that is, "stimulate" the brain and can also change how we act in life. I have previously blogged about studies showing that fictional narratives in toto can both provoke empathy and aggression. I also discussed aspects of this operating at the granular level, primarily with metaphor, in my long review last July of James Geary's superlative survey I is an Other: The Secret Life of Metaphor and How it Shapes the Way We See the World (New York: HarperCollins, 2011). Whereas the other studies utilize psychological tests to gauge the effects of fictional texts, and Geary focuses on the relation between figuration and the mind, Murphy Paul's essay explores how descriptive words in narratives, as well as narratives as a whole, activate particular parts of the brain.

She notes that sensory words, in particular, spark not only the language-processing areas of the brain, but those that deal with those senses, so that "lavender," "cinnamon," and even "soap" make both brain regions fire up, and that according to a 2006 study in the journal NeuroImage, when researchers in Spain had participants read words with strong odor associations alongside more odor-neutral words, an MRI showed their olfactory cortex lighting up for the odor-associated words, but not for the neutral terms. "Coffee" yes, "chair" no. Similarly, last month, a team of Emory University researchers wrote in the journal Brain & Language that when when participants in a study they were conducting read metaphors involving texture--"a rough day"--their sensory cortex, the area of the brain responsible for perceiving touch, became active. Writes Murphy Paul, "Metaphors like 'The singer had a velvet voice' and 'He had leathery hands' roused the sensory cortex, while phrases matched for meaning, like 'The singer had a pleasing voice' and 'He had strong hands,' did not."  And, lest you think this is only salient with the five senses, it turns out that descriptions of action also activated parts of the brain distinct from the language-processing centers; participants reading passages about characters grasping or kicking objects experienced activity in regions of the brain associated respectively with arm or movement.

So, you might be say: and? On one level, as Murphy Paul suggests, immersion in textual fictional narratives does entail a form of virtual experience that is hardly surprising to anyone who has ever written even a bad short story or read any fiction at all. On the other hand, it is significant that experimental methods are bearing this commonsense perception about the power of fiction out. The relationship between language, our minds and our bodies is not arbitrary. Let me say that again. The relationship between language, our minds and our bodies is not arbitrary.  Fiction, and literature more broadly, is powerful stuff.  Moreover, Cartesianism and all that has folowed in its wake (or the Platonism of The Symposium) really did get it wrong; the Plato of The Republic, like Aristotle in his Poetics, got it right. Indeed, to quote Murphy Paul, "The brain, it seems, does not make much of a distinction between reading about an experience and encountering it in real life; in each case, the same neurological regions are stimulated."  She also cites University of Toronto emeritus psychology professor Keith Oatley, whom I also cited in an earlier blog post, who argues that fiction offers a particularly powerful mode of simulation running in readers minds simular to ones running on computers.

Murphy Paul concludes her case by citing some of the material I previously pointed to regarding the effects of fiction on creating empathy--though she doesn't cite the aggression studies--and locates this in "novels" (though the studies show that movies have a similar effect, though many fictional TV shows appear not to), but I would argue that any kind of fictional, textual narratives, from short stories and tales up through full-length works, including ones purporting to be "nonfiction" but which are actually mostly made up, probably have the same effect. (Think James Frey.) She also makes a quick slide from "novels" and "fiction" in general to "great literature," which she avers "enlarges and improves us" (and that was part of Samuel Richardson's aim, as it has been many another fiction writer), but I think she's leaving out the fact that all kinds of fiction, including much that isn't "great" or barely "literature" at all, can have powerful effects on readers, for good, yes, and sometimes for ill, or sometimes with no evaluative appraisal possible. You have read the book, been affected in ways even you don't grasp, and how you act in the world, who's to say. The effects of the wretched novelist I describe above we know are hardly "enlarging or improving," unless selfishness, greed and antisociality are considered moral and social "goods". There too is a great deal of fiction, particularly from the 19th century on, that aims not towards moral uplift but towards simply getting the reader to think about the world, and words themselves. It is deeply ethical, even as it does not push us in one direction or another. I think of Moby Dick, say, or The Red and the Black, or the stories of Anton Chekhov and the countless writers, including this blogger, who toil in his wake.  And, what are the aims of those beloved and not-so-well-written Twilight novels, or the newest sensation, the Hunger Games trilogy?  Do we know or even need to know? Do the writers? Do readers? Do scholars? Because readers are not setting these works without things occurring between their ears....

One final point I'll make that links back to the first half of Murphy Paul's essay is this: I always stress to my students that attentiveness to language itself, including precision in description, but especially sensory description, use of figuration, varied syntax, and vivid verbs, alongside the other fundamentals--character, plot, voice, tone, dialogue, pacing, structure, beginnings and endings, etc.--are key to improving their work. I can see from their revisions that they grasp this, but in the future, I will use this article as another persuasive device. Stronger verbs than compound formations using the necessary but weak verbs "to be," "to have," "to get," etc., are often hallmarks of beginning writers, and it's thrilling to have confirmed what I try to convey, but also experience myself when reading fiction, mine or others: that our brains start firing when we read words that evoke the senses, or activate our mirror neurons, and immerse us in a world that at least initially exists only on the page but comes a real world to and in and for us--that is, if we or someone else can properly create it.

Can Fiction Improve Empathy and Provoke Aggression?

One of the newer areas of literary scholarly and critical inquiry, at least over the last 10 years, has involved exploring philosophical theories of mind, cognitive linguistics and neuroscience, each distinct, related but not always commensurate fieds, in relation to literature and the arts more broadly. What also has occurred over this same period is that psychologists and brain scientists have increasingly been thinking and conducting research on how the various artistic genres function and what effects they have, in a cognitive and biological sense. (Humanists and scientists in other older fields, such as philosophers going back to Plato, have extensively examined and theorized about the functions and operations of literature and the arts; aesthetics is one of the oldest rooms in the house of Western philosophy, and factors into philosophies across the globe.) I won't dare speak to the literary scholarship involving theories of mind and cognitive neuroscience, but I found two recent articles on psychologists' studies of fiction's effects quite fascinating, not only for what they have to say about the genre's power, but also for what one researcher argues the effects this new understanding about the art form might play, especially on public policy.

Before describing the studies, let me posit that many artists and many who appreciate the arts intuitively grasp how specific artistic genres and forms work.  This is no less true for architects or dancers as it is for poets or fiction writers.  For fiction writers in particular, I would also posit that many recognize in their own experience as writers and readers what's discussed in the studies mentioned below.  As I pointed out in my July review of James Geary's fine survey I is an Other: The Secret Life of Metaphor and How it Shapes the Way We See the World (New York: HarperCollins, 2011), sometimes what we grasp intuitively is correct, that our understanding of how things, especially language, function is, if not always empirically verified or verifiable, sometimes still right at a deeper level, and yet there remains so much still hidden to us and only slowly being revealed concerning how language works; there is so much that exceeds or eludes many of the popular or dominant theories, including some long held by major scholars and critics.  As Geary's book points out, othering--making oneself an other--is constitutively wired into language; it is built into our understanding of the world through language.  As he argues quite effective, the subject of his book, metaphor, turns out to be more than a mere trope or rhetorical device, but intimately connected to our mental and bodily experience in the world.

But what does this have to do with the articles I'm talking about? According to two studies recently cited in the Guardian, passages in fiction or fictional works in toto appear to "improve" and affect empathetic feeling in their readers. Concerning those fictional passages, Alison Flood relates how a University of Buffalo team, led by Shira Gabriel and Ariana Young, "gave 140 undergraduates passages from either [Stephanie] Meyer's Twilight or JK Rowling's Harry Potter and the Philosopher's Stone to read." In the former text (which I have not read), a character describes what it is like to be a vampire; in the latter, the young wizards are sorted into their respective Hogwarts Academy houses. The researchers then conducted successive computer tests, using personal pronouns and keywords, to measure identification with and as vampires, and then and as wizards. As it turns out, the study, published in Psychological Science, found that the students reading the text involving a description of vampirism were more likely to identify as vampires, while the students reading the text involving the youthful wizards self-identified as wizards. What the researchers also found was something that writers and readers have long known, which is that
"Belonging" to these fictional communities actually provided the same mood and life satisfaction people get from affiliations with real-life groups. "The current research suggests that books give readers more than an opportunity to tune out and submerge themselves in fantasy worlds. Books provide the opportunity for social connection and the blissful calm that comes from becoming a part of something larger than oneself for a precious, fleeting moment," Gabriel and Young write.

In a second study Flood cites, University of Toronto psychologist and novelist Keith Oatley gave 166 readers either a translation of Anton Chekhov's actual story "The Lady with the Little Dog" (which my undergraduates and I will be reading and discussing in just a few weeks!) or a more linguistically neutral, documentary account of the plot and characters featured in the story. What Oatley found upon measuring readers' personality traits and emotions before and after the story was that those who read Chekhov's "unadulterated" story, a profound and deeply complex essay in imagination and feeling, were found "to have gone through greater changes in personality--empathising with the characters and thus becoming a little more like them," while those reading the documentary account were less likely to have done so. (I also thought of Rainer Maria Rilke's extraordinary poem "The Archaic Torso of Apollo," which lyricizes and dramatizes what this study demonstrates; the experience with the statue marks the speaker not just empathetically, but transforms him, leading to that final, arresting line: "du mußt dein Leben ändern": you must change your life, but also: you must make yourself an other/another ("other" in German is ander).)

To quote Oatley:

"I think the reason fiction but not non-fiction has the effect of improving empathy is because fiction is primarily about selves interacting with other selves in the social world," said Oatley. "The subject matter of fiction is constantly about why she did this, or if that's the case what should he do now, and so on. With fiction we enter into a world in which this way of thinking predominates. We can think about it in terms of the psychological concept of expertise. If I read fiction, this kind of social thinking is what I get better at. If I read genetics or astronomy, I get more expert at genetics or astronomy. In fiction, also, we are able to understand characters' actions from their interior point of view, by entering into their situations and minds, rather than the more exterior view of them that we usually have. And it turns out that psychologically there is a big difference between these two points of view. We usually take the exterior view of others, but that's too limited.
Or to put it another way: reading fiction allows us to enter those other lifeworlds quite deeply, imaginatively, psychologically and affectively; we become those other people, or identify with them, even if negatively.  We become part of the fictional world, even if temporarily; we change our lives, if only in the moments while in and shortly after leaving a fictional text. (I would argue this occurs in an engagement with other works of art too, as many others have written far more eloquently and persuasively than I ever could.)  A connection occurs--our inner and outer worlds fuse in the experience of reading the text, we draw upon and redraw the fictional world in our heads. And we leave it changed, even if temporarily. (Think of J. W. G. von Goethe's The Sorrows of Young Werther, and its powerful, often deleterious effects on the youth of Romantic-era Germany; think of the Victorian era concerns about the effects of fiction on young women, both good and bad; think of the Beat era's poetry and fictional narratives, which not only captured the experiences of youthful social and cultural rebellion, but provided pointers for readers. And so on.) To those who've read a bit of philosophy or literary theory of an older sort, doesn't this sound familiar?

But it's not just empathy. In the September 7, 2011 issue of Miller-McCune, Tom Jacobs describes a  Brigham Young University research team study, led by psychologist Sarah Coyne, on the relationship between fictional accounts of two types of aggression and behavioral responses.  Coyne previously conducted studies on violence and popular culture, but had not previously studied fiction, so she focused on it in this one. According to Jacobs's article, the study shows that exposure to an account of violence in literature can effect an aggressive response to provocation.  Jacobs is clear to state that Coyne's study does not claim that "reading a fictional account of an aggressive action increases belligerent behavior," but that reading fiction containing one of two types of aggression, physical, or outright physically assaultive action, and "relational," or actions that upset a person's relationship in a group, resulted in responses marked by the particular type of aggression featured in the work.  In the first study, readers of material featuring physical aggression were more likely to respond with physical aggression when provoked during a video game test; in the second study, readers of texts featuring relational aggression responded with that form of aggression when provoked in a similar virtual game. As Jacobs says:
In both cases, provoked people who were given the opportunity to engage in a specific form of retaliatory violence were more likely to do so if they had just read a fictional account of similar activity.
He again notes that reading fiction does not increase aggressiveness, but that having a scene or mental experience, even fictional, of aggression--not a mere picture or mental image, as Wittgenstein might caution us to be wary of describing it, but something more complicated and nuanced, involving neural mirroring and affect, and embedded and embodied in language--can impact our subsequent behavior.  This also parallels what Geary suggested in terms of how certain words, terms, and figuration of many kinds, can affect and effect responses in us that we do not consciously register.

I mentioned that one aspect of these accounts that interested me was the implication one of the researchers, Keith Oatley, drew from the knowledge his study provided. He argues that his is the first "empirical finding" he knows of--though, as we see, there are apparently others--demonstrating a psychological effect produced by reading fiction.  What philosophers and literary scholars have long argued, he has demonstrated through a scientifically validated experiment, i.e., an empirical method.  Professor Oatley thus thinks we could--and ought--make the case that fiction writing might have instrumental value for readers--students, everyone--and thus "economic" value, in our society.  Oatley's specific argument is that "reading fiction improves understanding of others" in that it can improve interpersonal understanding, and thus might be useful in a range of fields, including business studies, law, and so on. While I agree that reading fiction can have instrumental value, I'm not sure I would go so far as to say it "improves understanding of others," let alone for everyone, because as I see the studies, what's going on is that it might not entail more understanding, but rather something antecedent to that, which is to say, pre-rational emotional connection and empathy, or, as the latter study suggests, negative behavioral responses to provocation.

Either way, what all these studies suggest is what writers and readers know--and what Plato warned about concerning poetry, which is to say, imaginative uses, in particular forms, of language--which that literature, and fiction specifically, are more important to and powerful for and on us than they're often taken to be, even by people interested in studying them.  In that sense, then, Oatley is writing--reading fiction is certainly worthwhile, and studying what it does is worthwhile too. Learning to read it, write it, and understand its effects are also truly worthwhile. (He does not discuss it at all, but we should also be aware of another instrumental possible use of this mode of language, which Geary suggests is possible: propaganda.)  I'll only add that none of these studies look at language at the micro level; none studied syntax, meter, pacing. None studied word choice, connotation, denotation, rhetoric. None studied figuration or tropes in any way. None of the three explore the narratives morphologically.  Instead, they look only at fictional narrative in the holistic or macro level, but suggest that fictional narrative, by itself--and the range in terms of talent, skill and art between the work of Stephanie Meyer and Anton Chekhov, I will dare to say, is great indeed--has powerful effects that should be explored more, and estimated in a different way.  I cannot think of a serious fiction writer or poet I know who doesn't already.
