THE ATTENTION TROVE
A Collaborative Archive of
Readings, Links, and Sundry Sources
From the founding of the "Friends of Attention" in 2018, the group has circulated sources of interest to those who work on attentional activism. Some of the Friends are teachers with relevant syllabi, others have collated samizdat "readers" or made showcases of attention material on Vimeo or Youtube. In 2022, David Landes (Duke University) undertook the heroic task of gathering and organizing the community to pull this material together, and he generously supplemented it with his own archive. This is a live and growing repository of material we think is of value to anyone who cares about radical human attention, and forms of resistance to attentional commodification.

Welcome-To-Attention Texts [non-scholarly]

Deep Play: Notes on the Balinese Cockfight, Clifford Geertz, from The Interpretation of Cultures, 21p. Example of interpretive anthropology where culture is read like a text. Example method: thick description (rather than thin description)
Theory as a Way of Seeing and Thinking, Stan Deetz, 6p. Seeing is a theory-laden process; observation requires concepts; our observations result from our starting theories, which function to direct attention, organize experience, and enable useful responses
Wabi-Sabi: For Artists, Designers, Poets & Philosophers, Leonard Koren. An example aesthetic as a mode of attention; contrasted with modernism
Exercises in Style: 21st Century Remix, Bethany Brownholtz. A two-paragraph narrative retold through different genres; example of 40 attentional modes taken upon 1 thing
Metaphors We Live By, George Lakoff. Intro to the symbolic dimension of attention: metaphors shape attention, not just via representation but also in the literally by how we conduct action
The Design of Everyday Things, Donald Norman, Ch 1&4. Intro to the material dimension of attention: a language for how designed objects shape attention; e.g., constrains, affordances, system maps, signifiers
The Medium is the Massage: An Inventory of Effects, Marshall McLuhan. Iintro to the material dimension of attention: a language for describing how media technologies interface with the body to shape the media that attention occurs through. Presented as an anti-book that performs it's own bookness by breaking textual conventions. The effect: to artfully disrupt your readerly routines, stoke attentional self-awareness, recover lost possibilities in a given medium• Audio Version: The Medium is the Massage: An Inventory of Effects, Marshall McLuhan (Audio version to compare with the written version. The anti-book in audio format! Performs the same concepts in the auditory "accoustic space" rather than the texts "visual space". Best to read the text and listen to the audio in tandem)
• Marshall McLuhan’s Theory of Attention: How to Become a Media Psychonaut, David Landes. Lists & explains McLuhan’s concepts of attention in the section titled McLuhan’s Implicit Attentional Concepts of Eco-Formed Attention p.3-7.

Keys to Drawing, Bert Dodson, p.8-25 of the original page numbers (p.9-26 of the pdf). Wonderful example of how an art/craft is taught through training its underlying attentions.

Serious Noticing, James Wood. 3 revisions of the same 8-page essay about attention. An argument for literary types of attention involved in storytelling and human observation. Serious noticing is both method and product of storycraft. Reading all 3 drafts shows Wood reworking his own storycraft, role modeling how one arrives at serious noticing through text
1st version, 2010
2nd version, 2013
3rd version, 2014
Why the World Needs ‘Dataism,’ the New Art Movement That Helps Us Understand How Our World Is Shaped by Big Data Article: art thru the lens of data and data literacy; positions art as attention engines to teach what words can't
Thank You For Arguing, Jay Heinrichs Ch 1-6, 12, 20-22, 24-25. Rhetorical concepts that function as ways of attending to/through argument. Reading notes of how his rhetorical concepts are also attentional.
Fourteen Ways to Interpret the Constitution, Brad Reid. [4p. Great fast illustration of “the hermeneutic question”: choosing an interpretive lens in any situation, especially in law by these 14 common lenses to legal interpretation]
Attention-Related Videos [non-scholarly]
To See or Not To See, Bretislav Pojar, 1969, 14 min. Ignore the film’s reductive binary argument ("how sould we look at the world, realistically or not?"). Useful is its depiction of attention as our inner author--an active, social, emotional, layered capacity for constructing experience
How Does an Editor Think and Feel?, Every Frame a Painting, 9 min. Example attn situation: how a film scene is edited changes in the audience’s experience and meaning. There are no rules or consistent “right answers” of how to do it well. For the film editor, each scene is its own attention situation, requiring decisions on how to construct it based on their goal and sense of audience attention.
Century of the Self, Adam Curtis, 4 1-hour videos. Documentary telling the story of history’s largest and most sophisticated attention industry. Provides a context of where our common “normal” kinds of attention come from and how their manufacture aims for "consumption beyond reason".
Santa Goes to Therapy 4 min. Santa character read through the lens of psychotherapy. The language of mental-health diagnosis recasts the familiar Santa Claus. This use of psychology language concludes Santa exhibits schizotypal personality disorder. Demonstrates linguistic framing. Imagine refuting this argument within the same language of psychology (e.g., alternative diagnoses, altruism, trauma). Imagine refuting or supplimenting this diagnosis with a non-psychological discourse (labor, nationality, race, class, gender, etc.)
Why Baseball is Interesting, Daniel Coffeen, 1p. An interpretation of baseball through some new attentions you might never have used. Every paragraph takes a new attentional lens to a part of the game. Makes the familiar unfamiliar.
The Hidden Sensory World of Animals, Ed Yong, 9min. Different non-human sense organs create different attns
Fake Sounds Companies Add to Products, 9 min. The sonic configuration of attn. More of your world is designed for consumer experience than you may realize. Sensations (e.g., sounds) have associations of meaning. We are unconscious of many aural interpretations
How The Microphone Changed the Way We Sing, 7 min. Media shape attn, action, and art. A case study of how a new technology imposes technical parameters that a culture adapts to. Certain genres, styles, details become possible that weren’t before. Much (all?) of a culture is a result of its technological arrangement. Abstract ideas (e.g., “love”) are experienced in the image of its technology (e.g., microphone). Parallels: cameras, computers, automobiles, etc.
"Friends": Ross Geller without laugh track = psychopath, 2 min. Removing a material part changes everything. The change of music, color, and laugh track changes meanings, character, and whole scene
History of Media Literacy Part 1, 9 min. And Part 2 9 min. Media and technology are the most ubiquitous source of the material dimension of attention. Consider the difference between a first introduction occurring in person vs. over texting. vs. through snapchat vs. telephone. The medium shapes attention (recall McLuhan’s The Medium is the Massage above). “With every new medium, a new set of skills is required to navigate it.” “This history of media literacy closely follows the history of media technology.”
Blind and deaf people can teach us much about our senses, which are attention’s materialities
Seeing through One’s Ears, human echo-location, 3 min.
• Sound indicates “contour, dimension, size, position, layout, texture, density” about the environment
The Ben Underwood Miracle, 3 min.
• “I can hear the wall, I can hear the couch, and the TV and computer”
How Do Blind People Dream?, 1 min
Describing Colors as a Blind Person, 3 min.
Intangible Concepts To A Blind Person, 4 min.
• Born blind & explaining his perception of the sun, sky, fog, Great Wall of China, Grand Canyon, and space.
The body’s rhythms are always changing, 3 min. “The body, the heart, doesn’t have the same time-length between each heartbeat. If they’re the same, that’s extremely dangerous… The more exact the time-measures, the more dangerous… That means your body is not responding. It must respond…”
Smell, the forgotten sense, has untapped possibilities
Smellosophy: What the Nose tells the Mind, Ann Sophie Barwich 0:00 - 31:00 Q&A onward
• The science of olfaction, a material dimension of attention, the “language” of the nose is different than the other senses.
What Can the Experience of Smell Tell Us About Art?, Ann Sophie Barwich
• examples of smell-art and how we underutilize the nose (a material dimension of attention)
How Language Shapes the Way We Think, Lera Boroditsky 14 min.
• Evidence of particular ways in which the structure of language relates to the structure of thought/attention
• Exemplifies the Sapir-Whorf Hypothesis
The Science of Linguistic Relativity, Robert Sapolsky, 6 min.
• Same as Boroditsky’s topic but with a little more explanation and implications for your thinking about Essays
• Exemplifies the Sapir-Whorf Hypothesis
Legal analysis of the Laws Broken in Willy Wonka & The Chocolate Factory 21 min but can watch to 6:30 and skip to 18:26 for the final verdict and summary of legal liability. If you know the law, you’ll see this film differently. Meanings are remade. For example, how the opening premise of the film are illegal (child labor violation, illegal lottery). Law is exemplary of how symbols (e.g., knowing the law itself) changes the way you see. I hope you have seen this film for this class example. Otherwise, I probably ruined the film for you… or made it attentionally more interesting :)
What makes good acting on screen? A slo-mo analysis, 8.5 min. This slow-motion analysis may change the way you watch actors and make you more self-aware of their silences and conveying of internal/mental activity. “Good acting” is more than about merely resembling the outward appearance of things. It’s about conveying the inward significance of things via “noble lies” that enhance the storytelling fullness. [I’m adapting Aristotle’s and Picasso’s ideas of art here]
How To Do Nothing, Jenny Odell, 37 min [ignore the Q&A after]
