A Five Minute Nature Daydream May Make You More Energetic and Playful!
It’s the middle of the afternoon, the morning’s
coffee has long worn off, and the soporific effects of that lunchtime sandwich
are kicking in. Rather than gulping down
that energy drink, perhaps a little nature daydreaming might help. Today in my urban ecology class I investigated
this possibility.
The study was designed primarily
to initiate a conversation about the role of nature in human health and well
being. It comes as no surprise that active engagement in nature, running,
walking, engaging in restoration work, gardening and so forth has measureable
benefits for human health. A little more
surprising perhaps are findings that passive
engagement with nature, living in prettily landscaped surroundings has
positive effects on people and on their communities. Bordering on mystifying though are the
results of studies indicating that even views
of nature, pictures of nature or nature glimpsed through a window delivers
benefits to people. This skein of
research became big news with the publication of Roger Ulrich’s paper in Science demonstrating that patients with
views of nature through a window recovered more rapidly from surgery, required
fewer post-operative narcotics, and were less testy with their nurses.[1]
So, it was with a view to opening
up a discussion on this range of effects that I conducted a little experiment. There were 16 attendees – 14 undergraduates, 1
graduate students, and 1 post-doctoral researcher. Students were assigned one of two
pictures. One is a view down an alley in
Evanston – it has both a lot of vegetation but also has garbage bins etc. The other is of a living room (harvested from
the internet) which deliberate was chosen to look comfortable and with a
television.
I read the following prompt: “View
the picture you have been assigned.
Imagine yourself in this place and what you would typically be doing in
this setting. With the image in mind
contemplate this activity for 5 minutes.
Relax, close your eyes if you prefer.
When Heneghan calls time turn over the page and answer the questions.”
The questions were
On a scale of 1-5 (with 5 being
the highest for each factor and 1 being lowest) rate your level of
1. Overall energy levels (1 2 3 4 5)
2. Feeling of aggression (1 2 3 4 5)
3. Playfulness (1 2 3 4 5)
4. Peacefulness (1 2 3 4 5)
5. General satisfaction with life (1 2 3 4 5)
Then students were asked to
answer the following numerical puzzle
Mr. Brown has 8 black gloves and
8 brown gloves in his closet. He blindly picks up some gloves from the closet.
What is the minimum number of gloves Mr. Brown will have to pick to be certain
to find a pair of gloves of the same color?[2]
The results are summarized as
follows:
I analyzed the results using a
Mann-Whitney U test (run on SAS). There are probably more appropriate ways of
analyzing this data but this approach did reveal some exciting trends. By convention ecologists report effects as "statistically significant" when there is less than a 5% chance that
they are in error in reporting that two study populations differ. This is usually reported as p<0,05. By
this metric none of the responses among students was significant. That being said several difference in responses
to daydreams based upon the two landscapes were very close to this cut off
point.
For instance, self reported
energy levels after contemplating the urban nature scene averaged 3.25 compare with
2.375 when the living room was viewed. Calling
the two populations of viewers different in their energy levels is probably “safe”. The probability is about 5.8% that they
differ by chance (p=0.058) – good enough to be interesting.
Students arose from their
micro-slumber with an average playfulness score of 3.375 when they viewed urban nature but
a mere 2.375 after dreams of a living room.
The p-value associated with differences in playfulness scores was 0.065,
enough to be also worth thinking about.
There were no other substantial
differences in the response of viewers.
I did detect a greater restlessness of my living roomers during their 5
minutes of contemplation. In contrast,
the nature viewers were almost uniformly still and engaged in their meditation. I guess I just thought that this was cool!
The conversation was interesting
after the test. But, I will invite the
students in the class to comment if they care to.
Now, I am no social scientists,
and one thing I have learned from my social science colleagues in recent years
is that survey design if a complex business.
On top of this there are many design limitations in the implementation
of the study. For instance, I clustered
the hand outs in the room so that students would not look at their neighbors
and have a scene other than their designated one to think about. The replication is, of course, poor. And frankly, I didn’t have any particular well
articulated question in mind, or theoretical framework in which I was
working. I was basically tooling
around. To be very clear, this is not a publishable piece of work, being designed to swell a conversation. All of this being said, I think
we were all a little shocked by the results.
Oh, in case you are wondering half of the nature contemplatives solved the brain teaser whereas only a third of the indoor crew answered correctly.
[Update: I reran this experiment with 18 more students in May 2013 - same results, almost exactly. The reported energy difference were even stronger. The same methodological limitations should be stressed, but the results remain, to my thinking at least, intriguing!]

No Jordan and Morton Discussion Tomorrow
Because of some logistical
snafus (Heneghan’s) we will not meet tomorrow nor for a few weeks.
Here’s
the plan: We are reading The Sunflower Forest http://www.amazon.com/The-Sunflower-Forest-Ecological-Restoration/dp/0520272706/ref=sr_1_3?s=books&ie=UTF8&qid=1334175269&sr=1-3 And
The Ecological Thought http://www.amazon.com/The-Ecological-Thought-Timothy-Morton/dp/0674064224/ref=tmm_pap_title_0 side by side…back to front
etc.
Rather that read small sections at a time I am urging us all the
read both thoroughly in April and then we can convene every Thursday morning
11:30 am in McGowan S rm 204 in May. I shall send us out a reading
schedule soon.
Both books are now available in
paperback...let Liam know if you care to join us when we reconvene in May. Price of admission is having read the books!

Tim Morton’s Marinade: An Interdisciplinary Recipe for The Ecological Thought
“Quantity humiliates.68”p40
"68. TI, 137, 274" p 143"
From Timothy Morton, The Ecological Thought.
(TI, Emmanuel Levinas, Totality and Infinity: An Essay on Exteriority)
In the introductory sequence to
each episode of Clever
Apes, a science segment on WBEZ, a Chicago-based NPR affiliate, a small
explosion sounds its bang and a kid goes “Whoa!” That’s the sound of science.
But it may be more than
that. The frisson of a fantastic bang
can reverberate as the disciplines collide and that sound alone might be reason
enough, says Tim Morton author of The
Ecological Thought, to tempt us to indulge in an interdisciplinarity
exchange. “The ecological thought”, Morton
writes, “is intrinsically queer.
(Joining ecological thinking with thinking on gender and sexuality would
make a fantastic bang, and this is reason alone to try it.)”
The ecological thought is that everything
is connected, the living, the dead and the never-alive. Intertwined in this
mesh are strange strangers, entities with whom (with which?) we are connected
and yet cannot predict. The more we
learn about our mesh-mates the more crepuscular they seem. There is more to say on this, in fact there
will quite literally always more to say about this because there is no bottom
to get to – it is a mesh. I am
re-reading The Ecological Thought with colleagues at DePaul’s University’s
Institute for Nature and Culture and will write more specifically about the
book in the coming weeks.
For now, I want to comment on
Tim’s work as an interdisciplinary model. Not to promote it as the model, but
rather to ask what sort of interdisciplinarity it might represent, and moreover
to show what this particular species of interdisciplinarity looks like. I want to quantify it.
Now, if there ever was a thought
that’s going to transcend a discipline it will be the ecological thought, since
the ecological thought contains the disciplines that might try to grapple with
it. In her taxonomy of
interdisciplinarity (ID) Julie Thomson Klein reported that the defining
characteristic of transciplinarity TD (let’s assume here that TD is a variant
form of ID) is that it is transcending, transgressing, and transforming. [1] That the topic of Tim’s book is transcending
cannot be in much doubt for the reason stated above. As we are pushed to the brink in thinking the
ecological thought we are “goad[ed]..to greater levels of consciousness, which
means more stress, more disappointment, less gratification(though perhaps more
satisfaction), and more bewilderment.”
(ET, 135.) The ecological thought
transgresses in that we can’t be the same having really thought it. If Tim is correct we can’t be the same
because the thought nags us with the realization that we were never what we
thought we were. We are part of a
mesh. We have transgressed (Latin, transgredÄ«, to step across, OED) – we
have leapt out of our own skin, which never was much of a boundary anyway. The ecological thought will transform us – it
already has.

Culture as a Natural Product - Exploratory Notes
Niles Eldredge, curator of
invertebrate paleontologist at the American Museum of Natural History, has
maintained eclectic interests over the course of his career. He is an expert in trilobites (extinct early
arthropods), co-creator with Stephen Jay Gould of the punctuated equilibrium
hypothesis (which challenged conventional thinking on the tempo of evolutionary
change), a vocal opponent of creationism, an impassioned writer on contemporary
environmental issues, especially on the issue of biodiversity loss, and is
known for his collection of trumpets and cornets.
Eldredge’s initial interests at
Columbia University were in anthropology though during an ethnographic
fieldtrip to Brazil in 1963 he found himself more interested in collecting
fossils in a nearby reef than in life in the fishing village that the research team
was visiting.[1] He went on to receive his PhD in geology at
Columbia, but nevertheless retained an interest in culture, especially on the question
of connections between biological evolution – oftentimes restricted to
explications of changes in the anatomical hard-parts of organisms – and the
evolution of culture. Humans are
pronouncedly cultural organisms, an aspect of their constitution that confers
upon them behavioral flexibility and capacity for rapid change that exceeds the
speed of typical biological change. From
this perspective, can it be claimed this it is our capacity for culture that
primarily determines our species evolving relationship with our environment?
That culture in large part
determines our environmental prospects is a contention that Eldredge examines
in his book Dominion. To see the force of the argument one must take
the long view. The emergence of culture
must be seen as an outcome of those same evolutionary processes that produced,
let’s say, the compound eyes on a trilobite.
Eldredge says:
"We have reached our present precarious position as an outcome of an ecological evolutionary course on which our ancestors embarked at least 2.5 million years ago. And our deep evolutionary history - hence our deep evolutionary future - is a story of shifting positions vis-Ã vis our approach to the natural world and its component ecosystems."[2]

Launching a quarter-long informal discussion of Bill Jordan and Tim Morton's Work at DePaul
As some of you know William Jordan III’s book The Sunflower Forest: Ecological Restoration and the New Communion with Nature is out in paperback finally. Coincidentally, so is Tim Morton’s The Ecological Thought (out tomorrow, 2nd April). We are proposing a reading of both this quarter at DePaul. In particular we will hone in on the overlaps between the two writers on the “shame” issue, “dark ecology”, and the perennial question of the “other.” I have written a short introductory note on the overlaps here.
We will start with an orientation on Thursday 5th April at 11:30 in the McGowan conference room 1110 W Belden Av. and will collectively decide upon the reading schedule.
If you are planning on attending email Liam at lhenegha at gmail com
In and Of the City: The Cost of Urban Ecology’s Foundational Distinction
Urban ecology, the environmental sciences youngest and most
rambunctious cousin, is in a position to influence the design of the
cities of the future. Its clout comes from its willingness to think
big, to think about the ecology of entire cities as if they were just
any other ecosystem. Urban ecologists call this big picture view the
“ecology of the city”.
From this disciplinary perspective, Chicago is just another savannah, one where admittedly the commonest species is the human animal.
However, by taking this bird’s eye view of cities, is urban ecology losing sight of the bird-on-the-ground? I mean this quite literally. Is urban ecology losing it roots in natural history? Will the successful cultivation of relationships with decision makers, municipal authorities, city planners and other governmental powers-that-be, come at the expense of urban ecologists’ knowledge about birds, wildlife, beetles and the other creeping things inhabiting the city?
Are we (and I count myself in this troupe) urban ecologists, forgetting the world-fascination, the intense delight, that comes from direct encounters with nature in the city?

Soil Ecological Knowledge: Investigating Invasive Species and Restoration Management from the Bottom Up
Abstract for the Forest Preserve District of Cook County Symposium (April 19)
Three years ago a team of soil ecologists, including me,
coined the term soil ecological knowledge (SEK) to refer to ways in which insights
from the our discipline might be incorporated into restoration management. Formally SEK acknowledges interactions among
the principal components of the soil system as well as feedback between the
aboveground and belowground ecosystem processes. For restoration to achieve its complex ends intentional
and holistic integration of all aspects of the soil knowledge, physical,
chemical and biological is necessary.
Some of the motivation for the development of SEK approaches to
restoration emerged from work in the Forest Preserve District of Cook County. We illustrate the approach with examples of
managing in the face of invasion by exotic shrubs and earthworms.
