Neuropsychological damage to a visual process
(e.g., color, object identification, location, visual neglect) produces the same problems in imagery as in perception
Can Images Be Studied Scientifically? -Bottom line Imagery impacts memory
-Introspectionists said, "Yes" -Behaviorists said, "No" -observable behavior -Alan Paivio (1971) said, "Let's try this again" -Duel-coding (or "conceptual peg") hypothesis -Concrete vs. abstract words in paired-associate learning -Two codes are better than one (1. Verbal and Imagery)
Mental Rotation
-Shepard & Metzler (1971) examined dynamic (not static) imagery -Mental chronometry: measure reaction time to make same/different judgments for shapes that are at different orientations (mental rotation task) -Strong linear relation between reaction time and degree of rotation -The more you have to mentally rotate an image the longer it takes you to make a decision about it
Two smallest units of language
-phonemes, which refer to sounds. -morphemes, which refer to meanings.
The Four major concerns of psycholinguistics;
1. Comprehension - How do people understand spoken language? 2. Speech production - How do people produce language, included both mental and physical processes. 3. Representation - How is language represented in the mind? 4. Acquisition - How do people learn language?
Relationships Between Categories: Semantic Networks
1. Hierarchical Model (Collins and Quillian) -Nodes (concepts) are connected through links (relations) -Concepts organized hierarchically, show property inheritance -Cognitive Economy: Stored shared properties just once at a higher-level node
The topographic man
1. Research on the topographic map on the visual cortex indicates that looking at a small object causes activity in the back of the visual cortex, and looking at larger objects causes activity to spread toward the front of the visual cortex. 2. Subjects were then instructed to create small, medium, and large visual images while they were in a brain scanner. The result, is that when subject created small visual images, activity was centered near the back of the brain, but as the size of the mental image increased, activation moved toward the front of the visual cortex, just as it does for perception *Thus, both imagery and perception result in topographically organized brain activation
Is imagery Spatial or Propositional?
1. Spatial (Correct): Representation has the same structure as the thing represented -Retain properties of images 2. Propositional: Representations uses symbols or sentences; non-spatial -Propositions take the form or relation (argument)
Input Units Hidden Units Output Units
1. Units in a connectionist network that are activated by stimulation from the enviornment 2. Units in a connectionist network that are located between input units and output units. 3. Units in a connectionist network that contain the final output of the network. *A stimulus presented to the input units is represented by the pattern of activity that is distributed across other units.
Evidence for Spatial Relationships: Brain Imagining Studies
1. fMRI study of visual areas activated by perceptions and visual images (Le Bihan) *Activity in the in the striate cortex increased both when a personed observed presentations of actual visual stimuli (perception) and when the person was imagining this stimulus (imagery) 2. fMRI studies of mental images of different sizes (kasslyn, 1993, 1995) -larger images activated more early visual areas in occipital lope - just like perception -The topographic map refers to the fact that specific locations on a visual stimulus cause activity at specific locations in the visual cortex and that points next to each other on the stimulus cause activity at locations next to each other on the cortex

Prototype Approach: Does an object resemble a "typical" memory of the category? - Evidence: Effects of Protypicality 1. Fruit example 2. Sentence verification technique (RT) shows typicality effect -higher reaction time for apple than a pomegranate 3. Priming - Color Rosch 3. Exemplar Approach: Does an object resemble one or more examples of the category

fluent aphasia
A disruption of language, caused by brain damage, in which afflicted individuals are able to produce speech but the speech is not meaningful, and the individuals are not able to understand what is said to them.
Cognitive Economy
A feature of some semantic network models in which properties of a category that are shared by many members of a category are store at a higher-level node in the network. For example, the property "can fly" would be stored at the node for "bird" rather than at the node for "canary"

Lexical Decision Task
A procedure in which a person is asked to decide as quickly as possible whether a particular stimulus is a word or non word.
Back Propagation
A process by which learning can occur in a connectionist network., in which an error signal is transmitted backward through the network. This backward transmitted error signal provides the information needed to adjust the weights in the network to achieve the correct output signal for a stimulus.

Asked her subjects to "project" visual images of common objects onto a screen, and then to describe these images. Unbeknowst to the subject, Perky was back-projecting a very dim image of this object onto the screen. Therefore, The subjects descriptions of their images matched the images that Perky was projecting. *Not one of Perky's 24 subjects noticed that there was an actual picture on the screen. They had mistaken an actual picture for a mental image.

Categories provide definitions of groups of related objects.
Theory-Based View
Concept represented mentally in terms of our theory about them by considering certain important diagnostic features
Classical View
Concept represented mentally in which there are clear boundaries and features that something has (ex: a bachelor is male, human, and adult); has necessary and sufficient attributes
Probabilistic View
Concept represented mentally in which there are varying levels of category membership; having certain features makes it more likely that an instance belongs to a category
Advantages of the Connectionist Approach
Concepts are represented by distributed network activity Connection weights can be excitatory or inhibitory Networks can be trained!

Explanation oh how semantic information is represented in the brain that stated that the ability to differentiate living things are artifacts depends on one system that distinguishes sensory attributes and another system that distinguishes function.
Self-Report Data
Form of evidence in which the person is asked directly about his or her own thoughts or experiences
Amir Amedi
Found that when subjects were using visual imagery, some areas associated with non-visual stimuli, such as hearing and touch, were deactivated or their action was decreased. This may be because visual images are more fragile than real perception and this deactivation helps quiet down irrelevant activity that might interfere with the mental image.
Finke and Pinker
Four dot display presentation experiment. They argue that because their subjects wouldn't have had time to memorize the distances between the arrow and the dot before making their judgements, it is unlikely that they used tacit knowledge about how long it should take to get from one point to another.

Freedom
Category
Group of things that have something in common

He published a book called "Verbal Behavior" which proposed that language is learned through reinforcement.
Noam Chomsky's view on language
He published a book in the same year as B.F Skinner, titled "Syntactic Structures" which proposed that human language is encoded in our genes. He noted that the underlying basis of all language is similar. His most persuasive arguments against B.F's behaviorist view on language is that as children learn language, they produce sentences they have never heard, and have never been reinforced. Example of this is "I hate you, Mommy"
Giorgio Ganis
His results show activation at three different locations in the brain. 1. Perception and imagery both activate the same areas in the frontal lobe 2. Perception and imagery both activate the same areas in the temporal and parietal lobes of the brain 3. Perception activates more of the brain in the occipital lobe than imagery

Which approach works better in the description of how people use categories: Prototypes or exemplars?
It has been proposed that as we initially learn about a category, we may average exemplars into a prototype; then later in learning, some of the exemplar information becomes stronger. Research shows that the exemplar approach may work better for small categories and the prototype approach may work best for larger categories

Conceptual Knowledge
Knowledge that enables people to recognize objects and events and to make inferences about their properties.
Transcranial Magnetic Stimulation
Kosslyn and coworkers presented transcranial magnetic stimulation to the visual cortex while subjects were carrying out either a perception task or an imagery task. *The results showed that stimulation caused subjects to respond more slowly, and that Kosslyn concluded that the brain activation that occurs in response to imagery is not an epiphenomenon and that brain activity in the visual cortex plays a casual role in both perception and imagery
Imagery Neurons
Kreiman and coworkers found neurons that responded to some objects but not others. -For example, the records show the response of a neuron that responded to a picture of a baseball but did not respond to a picture of a face. The neuron fired in the same way when the person closed his or her eyes and imagined a baseball (good firing) or a face (no firing)
What is language?
Language is a system of communication using sound or symbols that enables us to express out feelings, thoughts, ideas, and experiences.

Does the "definitional approach" work for sorting objects? what is the "definitional approach to categorization?
NO. Cognitive psychologists do not use this approach. It means that we can decide if something is a member of a category by determining whether it meets the definition of the category. This definition works well for geometrical objects but not natural objects and human made objects
Are basic - level categories special

Patient M.G.S.
She had part of her right occipital lobe removed. Removing part of the visual cortex reduced the size of her field of view, so the horse filled up the field when she was farther away. This result supports the idea that the visual cortex is important for imagery
Martha Farah (Proposed a way out of the imagery debate)
She suggested that instead of solely relying on behavioral experiments, we should investigate how the brain responds to visual imagery. *Results of her experiment - accuracy was higher when the letter shown was the same as the one that had be imagined.
Alan Paivio

The idea that we can decide whether something is a member of a category by determining whether the objet meets the definition of the category.
Prototype Approach to Categorization
The idea that we decide whether something is a member of a category by determining whether it is similar to a standard representation of the category - called a prototype.
Old Representation of Thought
The idea that we store ideas as abstract representations in the case of language comprehension

Hierarchical
The organization of language
1) Input Nodes (question) 2) Hidden Nodes 3) Output Nodes (answer)
The pathway for "growing" a PDP (parallel distributed processing) network
Prosody
The pattern of pauses and pitch changes that characterize speech production. Can be used to emphasize elements of a spoken sentence, to highlight the sentence's intended structure, or to signal the difference between a question and an assertion.
place of articulation
The position at which a speaker momentarily obstructs the flow of air out of the lungs to produce a speech sound. For example, the [b] sound is the lips; the [d] sound is created by the tongue briefly touching the roof of the mouth.
Categorization
The process by which objects are placed in categories.
speech segmentation
The process through which a stream of speech is "sliced" into its constituent words and, within words, into the constituent phonemes.
Parsing
The process through which one divides an input into its appropriate elements-for example, divides the stream of incoming speech into its constituent words
linguistic relativity
The proposal that the language that we speak shapes our thought, because the structure and vocabulary of our language create certain ways of thinking about the world.

The proposal that the language we speak shapes our thought, because the structure and vocabulary of our language create certain ways of thinking about the world
Random Errors
The reason the library analogy of the model of knowledge fell down
Phonology

Which of the following has been used as an argument AGAINST the idea that imagery is spatial in nature?
The tacit-knowledge explanation
categorical perception
The tendency to hear speech sounds "merely" as members of a category-the category of "z" sounds, the category of "p" sounds, and so on. As a consequence, one tends to hear sounds within the category as being rather similar to each other; sounds from different categories, however, are perceived as quite different.
VOT (Voice Onset Time)
The time that elapses between the start of a speech sound and the onset of voicing
Generativity
The trait of a system that allows someone to combine and recombine basic units to create new and more complex entities (ex: linguistic rules)
Connectionist Network
The type of network proposed by the connectionist approach to the representation of concepts. Connectionist networks are based on neural networks but are not necessarily identical to them. One of the key properties of a connectionist network is that a specific category is represented by activity that is distributed over many units in the network. This contrasts with semantic networks, in which specific categories are represented at individual nodes. -Input units send signals to hidden units, which send signals to output units
D-structure
The underlying and abstract representation of a speaker's intended meaning in uttering a sentence.
Manner of Production
The way in which a speaker momentarily obstructs the flow of air out of the lungs to produce a speech sound (ex: air flow is stopped for a moment when producing the "t" or "b" sound)
manner of production
The way in which a speaker momentarily obstructs the flow of air out of the lungs to produce a speech sound. This obstruction can take several forms. For example, the airflow can be fully stopped for a moment, as it is in the [t] or [b] sound; or the air can continue to flow, as it does in the pronunciation of [f ] or [v].
Dual Coding Theory
Theory that imaginable materials, such as high-imagery words, will be doubly represented in memory; the word itself will be remembered with the corresponding image
Kosslyn's Theory of Perception and Imagery
Theory that there is a prime stored representation to create an image and that imagery is a pattern of activation in the visual areas and then attention selects for further processing
Transformation Studies
Theory-based view study that shows concepts thought to be natural kinds were not represented in terms of features or similarity (ex: raccoon turning into skunk vs. coffeepot turning into bird feeder)
Gelman-Markman Triad Task
Theory-based view task showing that similar tests using artifacts show more reliance on visible features, especially "natural kinds" (ex: bat vs. bird laying eggs)
Why are Phonemes and Morphemes so important?

When you learn a category, you acquire the prototype
Because it is fast - as many as 50 phonemes per second
Why is the perception of phonemes difficult?
Smith and Medlin 1981
Without concepts and categories, mental life would be chaotic.
Imageless thought debate
Wundt proposed that images were one of three basic elements of consciousness, along with sensations and feelings. This led to the Imageless thought debate: 1. (Francis Galton) Thought is possible without an image -Galton: people who had great dificulty formnig visual images were still quite capable of thinking 2. (Aristotle) Thought is impossible without an image *The behaviorists branded the study of imagery as unproductive because visual images are invisible to everyone except the person experiencing them.
Make sense of mixed results (look in notes for double dissociation)
You need attention to maintain a mental image -Visual perception necessarily involves bottom-up processing; visual imagery is necessarily top-down *The neuropsychological cases present a paradox: One one hand, there are many case that show close parallels between perceptual deficits and deficits in imagery. On the other hand, there are a number of cases in which dissociations occur, so that perception is normal but imagery is poor, or perception is normal but imagery is poor -The cases in which imagery and perception are affected differently by brain damage provide evidence for a double dissociation between imagery and perception. 1. One way to explain this (Behrmann) is that the mechanisms of perception and imagery overlap only partially, with the mechanism for perception being located at both lower and higher visual centers and the mechanism for imagery being located mainly in higher visual centers
Imagery Debate
Zenon Pylyshyn: proposed another explanation (rather than kosslyn's) a debate about whether imagery is baed on spatial mechanisms, such as those involved in perception, or on mechanisms related to language, called propositional mechanisms. -Just because we experience imagery as spatial, that doesn't mean that the underlying representation is spatial *The spatial experience of mental images, argues Pylyshyn, is an epiphenomenon: something that accompanies the real mechanism but is not actually part of the mechanism -Example: of an epiphenomenon is lights flashing as a mainframe computer carried out its calculations. The lights may indicate that something is going on inside the computer, but they don't necessarily tell is what is actually happening.
prototype
a "typical" member in a category. It is based on an average of members of a category that are commonly experienced.
Suppose we asked people to form simultaneous images of two or more animals such as a rabbit alongside an elephant. Then, we ask them basic questions about the animals. For example, we might ask if the rabbit has whiskers. Given our knowledge of imagery research, we would expect the fastest response to this question when the rabbit is imagined alongside
a bumblebee

an effect in which understanding a sentence that implies a movement away from yourself happens more quickly if the movement to reach for the response button is also moving away from yourself
family resemblance
an idea that philosopher Ludwig Wittgenstein proposed to deal with the problem that definitions often do not include all members of a category. It refers to the idea that things in a particular category resemble one another in a number of ways. this allows for some variation within a category so there is no definite criteria that every member of a category must meet.
Aphasia

basic units of meaning (test vs posttest, enter vs re-enter)
Phonemes
basic units of sound (bat and cat differ by one phoneme) - difficult perception because fast
Levels of categories
basic, superordinate, subordinate
Rosch provided evidence for the idea that the basic level is "psychologically privileged" what is special about basic level categories?
because going above it (global) results in a large loss of information and going below it (specific) results in little gain of information
Why are categories often called "pointers of knowledge"?
because once you know that something is in a category, you know a lot of general things about it and can focus your energy on specifying what is special about that particular object

Categorization task
compare the exemplar to the prototype (canary big overlap=fast // ostrich, small overlap=slow = typicality effect) - not reducible to necessary and sufficient
Theory-based view
concepts are not just represented in terms of visible attributes or apparent similarity (to a prototype), similarity is too flexible, concepts are represented in terms of our theory about them, theory=any explanation, concepts=organized by our theories, theories=determine what counts as attribute or feature, concepts=natural kinds not just represented in terms of features or similarity
Exemplar theory
conceptual category (birds) is represented by memory of all different examples (exemplars) you've seen, we categorize objects based on their similarity to previously stored instances, All instances (exemplars) of a category you have experienced make up your knowledge

Learning in the connectionist network is represented by adjustments to network
connection weights.
One of the key properties of the _____ approach is that a specific concept is represented by activity that is distributed over many units in the network.
connectionist
One beneficial property of connectionist networks is graceful degradation, which refers to the property that
damage to the system does not completely disrupt its operation.
Parietal lobe damage
damage to this part of the brain has a parallel effect in imagery making it difficult to describe relative locations of landmarks, but can describe objects, faces, and animals
Temporal lobe damage
damage to this part of the brain has a parallel effect in imagery making it difficult to report color or describe faces, objects, and animals, but can describe relative locations and landmarks
Not all of the members of everyday categories have the same features. Most fish have gills, fins, and scales. Sharks lack the feature of scales, yet they are still categorized as fish. This poses a problem for the approach to categorization.

Sometimes a behavioral event can occur at the same time as a cognitive process, even though the behavior isn't needed for the cognitive process. For example, many people look toward the ceiling when thinking about a complex problem, even though "thinking" would likely continue if they didn't look up. This describes a(n)
epiphenomenon.
If you say that "a Labrador retriever is my idea of a typical dog," you would be using the approach to categorization.

image rotation, scanning, mainly spatial representations
Parallel distributed processing models
in semantic networks concepts are represented by nodes which are symbols, local representation, concept representation is distributed across nodes, modeled after neuronal networks, start with 3 layers of nodes with connections between layers, (input nodes, hidden nodes, output nodes), random weights, ask question, gives response, give it feedback, model adjusts weights while learning
corpus of language

involves reading a list that consists of words and non-words.
Imagine that a young child is just learning about the category "dog." Thus far, she has experienced only two dogs, one a small poodle and the other a large German shepherd. On her third encounter with a dog, she will be LEAST likely to correctly categorize the animal as a dog if that animal
is a dog that does not bark.
Hierarchical nature of language
it consists of a series of small components that can be combined to form larger units. ex: words can be combined to create phrases, which in turn can create sentences, which themselves can become components of a story.
In drawing conclusions about the relationship between imagery and perception, a notable difference between them is that
it is harder to manipulate mental images than perceptual images.
Difficulty of speech perception
lack of invariance
hierarchical organization
larger more general categories are divided into smaller more specific categories creating a number of levels of categories

Olin and Bob are neighbors. Olin loves birds and his father works for the zoo. He has been to a dozen bird sanctuaries, and he and his dad go on bird watching hikes once a month. In contrast, Bob doesn't think much about birds. His only contact with them is in his backyard. It would be correct to say that Olin's standard probably involves
more exemplars than Bob's.
Sentence verification task
must quickly decide whether sentences are true (cats are birds)
Classical view
necessary & sufficient attributes (male, human, adult = bachelor, you either have these features or you don't) - classical view is wrong/rejected, if it were true, all exemplars should be equal
Probabilistic view
no necessary & sufficient attributes define concepts, having certain features makes it just more likely that an instance belongs to a category
Network
nodes and links are in a network
Why definitions don't work for categories?
not all the members of a category have the same features ex: different objects, all possible "chairs"
phonemic restoration effect
occurs when phonemes are perceived in speech when the sound of the phoneme is covered up by an extraneous noise. Ex: Richard Warren (1970) had subjects listen to a sentence, then replaces a phoneme in a word with a cough. They didn't notice that a letter was missing, but still understood. This "filling in" of the missing phoneme is an example of top-down processing.
speech segmentation
our ability to perceive individual words even though there are often no pauses between words in the sound signal.
Categorical perception
our categorization of phonemes shows abrupt boundaries, even when there is no corresponding abrupt change in the stimuli themselves

Parietal lobe
part of the brain that assists with attention and further processing of imagery; spatial properties, location, size, rotation, etc.
Area V1
part of the brain that is activated during visualization and imagery tasks; important for visual perception and mental imagery, disrupting V1 with magnetic pulses causes problems with vision and with visual imagery
sentence verification technique
participants are presented with statements and asked to answer "yes" if they think the statement is true and "no" if they think it isn't. doing this technique shows that participants respond faster for objects that are high in prototypicality than they did for objects with low prototypicality.
Wernicke's aphasia
patients studied by Wernicke, who had damage to their temporal lobe, produced speech that was fluent and grammatically correct, but tended to be incoherent.
Perky's imagery study (1910) had participants describe images of objects that were dimly projected onto a screen. The significance of Perky's results was that
people were influenced by the projected images when forming their mental images, even when they were unaware that the projected images were present.

spatial
If we were conducting an experiment on the effect knowledge has on categorization, we might compare the results of expert and non-expert groups. Suppose we compare horticulturalists to people with little knowledge about plants. If we asked the groups to name, as specifically as possible, five different plants seen around campus, we would predict that the expert group would primarily label plants on the ______ level, while the non-expert group would primarily label plants on the ______ level.
specific (subordinate); basic
syntax
specifies the rules for combining words into sentences. Ex: changing the sentence "the cat's wont eat" into "the cat's wont eating" is an error of syntax because the grammar is not correct.
Collins and Quillian explained the results of priming experiments by introducing the concept of _____ into their network model.
spreading activation
given-new contract
states that a speaker should construct sentences so that they include two types of information; 1. given information - information the listener already knows 2. new information - information that the listener is hearing for the first time.
late closure
states when a person encounters a new word, the persons parsing mechanism assumes that this word is part of the current phrase, so each new word is added to the current phrase for as long as possible.

the meanings or words and sentences Ex: changing the sentence "the cat's wont eat" into "the cat's wont bake" is an error of semantics because the meaning doesn't make sense.
Rosch and coworkers conducted an experiment in which participants were shown a category label, like car or vehicle, and then, after a brief delay, saw a picture. The participants' task was to indicate as rapidly as possible whether the picture was a member of the category. Their results showed
the priming effect was most robust for basic level categories.
categorization
the process by which things are placed into groups called categories.
syntactic coordination
the process in which people use similar grammatical constructions.

event related potential (ERP)
the rapid electrical response recorded with small disc electrodes placed on a person's scalp.
coherence
the representation of the text in a person's mind that information in one part of the text is related to information in another part of the text.
Phonology:
the sequence of phonemes that make up the word

the shortest segment of speech, that is changed, changes the meaning of the word. the word "bit" contains the phonemes of /b/ /i/ /t/ we can change bit into pit by replacing letter b with p.
Morphemes
the smallest units on language that have a definable meaning or a grammatical function. Ex: Truck consists of many phonemes, but only one morpheme. Truck means "one truck" and Trucks means "more than one truck" this has two morphemes.
common ground

"Stop consonants"
utterance requires a momentary blockage of the vocal tract
Prototype approach
we categorize items by comparing to the prototype of a category, if an object is similar to the prototype, it will be categorized as an instance of a category (which is more like the prototypical dog), concept is represented by a prototype, prototypes require exemplars and they emerge gradually, the first members are usually the prototypes, and hence those most tightly linked to a category, the last members will be more loosely linked, and hence will be last
Old Representation of Thought
we store ideas as abstract representations in the case of language comprehension
balanced dominance
when a word has more than one meaning but the meanings have about the same dominance. Cast (play cast) and cast (broken arm)
what does it mean when the family resemblance is high for items? low?
when the items characteristics have a large amount of overlap with the characteristics of many other items in the category. Low means little overlap
biased dominance
when words have two or more meanings with different dominances.
One reason why basic level categories may be "psychologically privileged" is that
you lose a lot of details when jumping to a global category, but gain only a few details by jumping to a specific category.
