Mind Without Representation: Ecological Psychology |
Stellarium is a free program that will simulate a planetarium on your computer so that you will always know what stars you're looking at and when something interesting will be appearing. It's quite addictive.
Two short excerpts about James Gibson's Ecological Psychology: these are written by people who DON'T actually agree with Gibson and his ecological view, but who are describing him and his work fairly objectively. (While they're sort of skeptical, personally I'm not!) It's difficult to sum up the approach in brief; the linked passages are decent outsider views, but they're still incomplete and fail to appreciate some subtleties and philosophical implications. Ecological psychology is an approach to problems of perception and other aspects of psychology that is very different from conventional mainstream approaches. Instead of looking at the mind as a kind of computer involved in the processing of information (which is what mainstream psychology assumes), it is concerned with how animals and people can directly detect information in the environment which will be sufficient to guide their actions. The phrase "directly detect" is why the approach is often referred to as "direct perception"; it implies that the information doesn't need to be processed at all, which is controversial to say the least, and which certainly flies in the face of many centuries of epistemology. (At the end of the excerpt is an example of what a conventional "INdirect perception" approach looks like, for comparison.) The term "ecological" refers to a view of the animal and its environment as an integrated and co-evolving whole, as opposed to the conventional approach which seems to view the animal as an arbitrary observer placed into an arbitrary context. The ecological approach was developed by James Gibson over the whole course of his career, and today the University of Connecticut is the world leader in promoting and pursuing this approach. In particular the Psychology Department's Center For The Ecological Study Of Perception And Action (CESPA) is dedicated to advancing research and theory in ecological psychology.
Spiders and turkeys and bears: some pictures from backyards (mine, my brother's). You're free to exclaim "oh my!" after reading the album title. Just something to look at if you're bored.
If you're looking for a break from studying, listen to a few minutes of Richard Pryor -- someone you'd probably heard of before he died in 2005, but might never have really known the significance of. A full appreciation of him would put him in a category with people like Muhammad Ali, not just other comedians. (Here's a decent writeup from the New York Times.) In the meantime there's his work, which is not just the clowning he's famous for from movies. If you're bothered by his use of that word that I won't print (which he plastered right across a couple of his album covers in the 70's!), listen through to the end of "Africa" at about 8:30 to hear the conclusion he finally reached.
[T]he term "cognition" refers to all the processes by which
the sensory input is transformed, reduced, elaborated,
stored, recovered, and used. It is concerned with these
processes even when they operate in the absence of relevant
stimulation, as in images and hallucinations. Such terms as
sensation, perception, imagery, retention, recall, problem
solving, and thinking, among many others, refer to
hypothetical stages or aspects of cognition.

Excerpt from an interview with philosopher Daniel Dennett
(from Jonathan Miller's collection titled States Of Mind)
on the strategy of investigating the workings of the brain by probing the
information processing capacities of the mind, rather than approaching
it directly through neuroscience. Note that this difference in
investigational strategies is also referred to as top-down vs. bottom-up
in a different context.
Two excerpts from Stephen Pinker's book How The Mind Works in which the Computational Theory of Mind is nicely described. Note that at one point, Pinker claims this theory is different from "the despised computer metaphor," which he suggests is the idea that the brain is exactly like a digital computer. But no one actually thinks that, and when people "despise" the computer metaphor, it actually is Pinker's own view that they mean. Pinker just wants to make it seem that no one could possibly have any reasonable objection to what he's saying. This is typical of Pinker, and part of the reason many people (including me) sometimes can't stand him; another believer in the Computational Theory of Mind, the famous philosopher Jerry Fodor, found enough to disagree with in this book that he wrote his own book as a response, titled The Mind Doesn't Work That Way. These pages are an interesting read nonetheless. |
Some Introductory notes:
three important dates in the history of psychology; four defintions of
psychology; a timeline and four terms that are central to epistemology

Two commentaries on the continuing vitality of behaviorism despite rumors of its demise:
Excerpt from Out Of Our Heads by Alva Noë: from an introductory chapter of a book by one of the few philosophers to question the seemingly fundamental notion that the mind is the product of the brain. It's important to understand that he doesn't promote any supernatural alternative, but rather argues that the basic concept needs to be reconsidered.
Crimson by Josip Novakovich is a moving and disturbing short story that features this intriguing passage -- an insight that is certainly knowledge of a sort, but not scientific knowledge: "Milan thought how strange it was that he should be held responsible for the past, three years ago, when he was conscripted and enslaved--when he wasn't even himself. 'We all have multiple personalities,' he said. 'One of us is the past, and another the future, and there's no present me. We are vacant right now--spaces through which the past and the future disagree.'" Knowledge comes in many varieties, and whether it's scientific, or poetic, or spiritual, or intuitive, or common-sense, etc., all of these are valid ways of knowing the world for different purposes and contexts. Science is not the be-all-and-end-all of knowledge, or the ultimate arbiter of what is real for all purposes, but is a specially constructed tool for uncovering certain kinds of facts about nature using certain agreed-upon types of evidence.
Here are a couple of ways to get things really wrong, in viewing the relationship between science and religion:
Outline of epistemology for psychology:
This web page
highlights some differences between empiricist and rationalist
approaches to psychology, and calls them Platonic and Aristotelian in
character -- but be warned: they are not exactly what Plato or Aristotle
would have claimed, they're just descriptions of the spirit of the two
families of claims!

Some excerpts from Plato's Dialogues: They're very readable even in this classic translation from the 19th century. "Meno" features the slave boy demonstrating that he knows the Pythagorean Theorem (this version with illustrations may be easier to follow). Book VII of The Republic contains the famous Allegory Of The Cave.
David Hume on causation, from An Enquiry Concerning Human Understanding (1748) -- in case you want to see where questions about causality all began. (See also the famous conclusion.)
Outline of Logical Positivism: This is a very brief sketch of the philosophy of science known as Logical Positivism, which was very influential in the development of psychology in the first half of the 20th century. It's mainly of interest for the concluding segment, an excerpt from the first English-language manifesto of logical positivism, in which Hume's influence is explicitly acknowledged.
Chomsky, Noam (1959). A Review of B. F. Skinner's Verbal Behavior. Language, 35(1), 26-58. The famous critique of the behaviorist approach is fairly difficult, but rewarding if you're interested.
Language Development: here are a couple of brief passages scanned from Erika Hoff's text that describe the Chomskyan view of language acquisition, for those who want something more than their notes to refer to. It also makes some of the same points about behaviorism and cognitivism as I made in class, and emphasizes that behaviorism fails as a theory of language. Note that connectionism / parallel distributed processing / neural network models are mentioned in passing as embodying both nativist and empiricist elements. We described them as a type of information processing model (or "computer"), and therefore rationalist. At the same time, they are inspired by arch-empiricist David Hume's view of simple ideas "thinking for themselves" through the application of a small set of rules, rather than the complicated sets of instructions in a familiar computer "program" that might be more in line with Descartes's thinking. |
Summary of the experiment on patients with either a damaged amygdala or hippocampus that was mentioned in class, but is not in the textbook. |

PDP models are described here in an excerpt from the 2nd edition of Goldstein's cognitive psychology textbook, using somewhat different examples and presentation than the 3rd edition. This can serve as a supplement to the 3rd edition's coverage in case it is more understandable or helpful. Note that the passage is concerned with connectionist models of the organization of memory and how concepts can be related to one another; but keep in mind that the approach is much more general and has been used to model language learning, perception, reading, and many other aspects of human information processing. Apart from their applications in psychology, it's likely that neural networks are being used to recognize your preferences when you use services like Pandora or Netflix, or to decide which emails you receive are probably spam.

Video of the peregrine falcon and the gos hawk in flight. Especially note at 1:43 how the gos hawk navigates a cluttered environment, and consider whether the evolutionary route to that skill really seems to have involved examing a sequence of static images that come in quick succession, as the conventional approach to perception seems to suggest.
A point-light display of a human walking, which doesn't look like much of anything when seen in a single static frame, but reveals various characteristics of the person when viewed in motion. Movement isn't something perception has to account for -- rather it's essential to what perceiving is.
An illustration of top-down processing, as noted above in a different context, and repeated here: in reading the words "THE CAT" as printed in the link, bottom-up or purely stimulus-driven processing is not sufficient to decide whether the ambiguous letter is an A or an H in each word, since it could be either; instead the reader makes use of higher-level knowledge (of vocabulary and word spellings) which is normally the end product of the reading process, to resolve the ambiguous stimulus in each context through what is known as top-down or knowledge-driven processing (i.e., the knowledge that there is a word C-A-T in English, but no word C-H-T).
The Rubin Vase illusion, illustrating figure-ground switching in a bi-stable display (i.e., a picture that can be seen in two different ways equally clearly).
Two versions of Roger Shepard's monster illusion: with a ruler to show the same heights, and with a movable monster to show the overlap; other illusions are available from these sources as well. Unconscious inferences seem to be based on premises about convergence of lines and relative retinal image size, and their implications for object size.
The Ames Room Illusion, and its explanation.
Inverted faces are more difficult to identify, though it can still be done at some cost. (Look at this and this for comparison. Or view a different face if you prefer (give it a few seconds to load).
Hunting the Hidden Dimension, an episode of the PBS series NOVA that explores the mathematics and applications of fractals in a very accessible and interesting way. The program has apparently expired from the PBS.org streaming site but can also be viewed on youtube. The segment from 8:02 to 10:10 is a nice capsule summary of how fractals describe nature differently than traditional mathematics.
Arcadia, Tom Stoppard's 1993 play as described in Wikipedia. If you choose, you can read this entire synopsis including details of the plot, and it will not ruin the experience of reading the actual play -- which, I remind you, is quite a fast read and is available at libraries and could change how you look at the world. But if the synopsis bores you, don't let that put you off. You liked Shakespeare In Love, didn't you? Same author. Also Rosencrantz and Guildenstern Are Dead, and Travesties, mentioned elsewhere on this page.

The auditory sensory memory experiment by Darwin, Turvey and Crowder (1972) used an auditory analog of Sperling's partial report procedure. Presentation of stimuli to the left ear, right ear, or both ears (perceived as coming from a "middle" ear) was followed by a visual signal to report items from the left, right, or middle set. Whole report resulted in an average of 4 of the 9 items being recalled, while partial report suggested that 5 of the 9 items were available -- a small but statistically significant difference. Delayed partial report indicated a duration of up to 4 seconds. See results here. |
Summary of arguments about the "modal model": this list provides an outline of the arguments and evidence concerning the first explicit model of memory as covered in lecture, along with citations and page references when possible. |
Excerpt from Alan Baddeley's 1990 textbook Human Memory which can serve as a resource for various experiments discussed in class that are not in the Goldstein text. See also the excerpt from Mark Ashcraft's 1994 textbook Human Memory And Cognition (2nd Ed.) as an alternative treatment of similar material. These are meant only as a supplement or backup for class notes, if needed.
Working memory dual task results from Baddeley and Hitch (1974), as described in the Baddeley textbook excerpt above. Participants were asked to hold anywhere from 0 to 8 digits in memory while simultaneously classifying sentences such as "B is not followed by A" as true or false when shown stimuli like "A B". The time it took to verify those statements increased with digit load, but never became impossible even while holding 8 digits in memory (which, one assumes, would fully occupy short term memory). Thus a model was proposed that allowed both tasks to be done at once, though with a shared pool of limited cognitive resources. |
The late Henry Molaison, of Windsor Locks, CT
Clive Wearing is a famous patient suffering from anterograde amnesia like Henry ("H.M."), caused by a viral infection that attacked his brain (presumably including the hippocampus). As you see from this video he has the additional burden of considerable retrograde amnesia. His case is outlined here and is also featured in Oliver Sacks's latest book titled Musicophilia. Note that there are many other clips available on youtube, some of which bear the misleading title of "man without a short term memory" or some such thing, when it's apparent that like Henry, his short term memory is intact -- it's just his ability to move its contents into long term memory that is impaired.
Analysis of the film "Memento" by Andy Klein on salon.com. If you haven't seen the movie you should try to puzzle your way through it first, because it's a challenge; the main character suffers from an H.M.-like anterograde amnesia, and you are put in the same situation through the technique of having the story told backwards -- so you never know what past events preceded the current action of the film. The short-story version is quite different from the movie but pretty interesting on its own.
