<p>Certainly. </p>

<p>It depends on the type of learning process of a person. One can be better at remembering images, so he might access the images first when trying to define an object/event/etc. This can be thought of as having a <a href="http://en.wikipedia.org/wiki/Eidetic_memory">photographic memory</a>. </p>

<p>The main reason why most people think with words is because it is a much more sophisticated and structured learning process, and is taught young. Missing the opportunity to learn a language when youre young would most likely cause them to develop a different way of processing information.</p>

<p>Same way goes for someone with visual agnosia. He might develop another way of recognizing objects. For example to use other senses (much like the blind uses his hands to "see"). So one with agnosia would have to use another approach to understand that the fork and the cutting board are two different objects.</p>

<p>Developing (with time or by injury) agnosia or aphasia at some point in your life would certainly mess your usual way of processing information; and it would be very hard to rebuild a new recognition system as old habits are hard to break.</p>

<p>On another note, some friend of mine claims that he consciously thinks with noises when playing and writing music. </p>

<p>It is hard to imagine what evidence might be found of thoughts existing without language. Even <a href="https://en.wikipedia.org/wiki/Feral_child" rel="nofollow noreferrer">feral children</a> encounter language (either verbal or nonverbal) through limited contact with people or animals, and lab animals communicate nonverbally with researchers, even if only through their environments (the researcher observes the animal's behavior, and the animal observes how the researcher changes its environment, e.g., its food, waste, and cage furnishings). For reasons such as these, the prospect of thought without language may be somewhat untestable. Producing a sentient being that is never allowed the opportunity to communicate with others would also be unethical by most means I can imagine.</p>

<p>As for your (largely unrelated) question about object discrimination in the absence of recognition, I can't offer any insight in the context of visual agnosia per se, other than to point out that (according to <a href="https://en.wikipedia.org/wiki/Visual_agnosia" rel="nofollow noreferrer">Wikipedia</a>), "Visual agnosia...is not due to a deficit in...language." However, outside that context, I would recommend watching <a href="http://youtu.be/lfGwsAdS9Dc" rel="nofollow noreferrer">an episode of Scientific American Frontiers, "The Man with Two Brains"</a> that I mentioned in <a href="https://cogsci.stackexchange.com/a/5459/4086">another answer of mine</a> just yesterday! The effects of lacking communication between one's cerebral hemispheres are different from visual agnosia, but give some insight into how unknown objects (e.g., crude drawings) may be identified and differentiated in the absence of linguistic function, which is generally left-hemisphere-dominant. In this episode, Mike Gazzaniga also demonstrates how his split-brain case study subject attends differently to the components that comprise larger objects vs. the overall unity of those objects as one <em>meta-object</em> (coined here for lack of a better term), depending on which hemisphere's visual field processes such an object comprised of smaller objects. The left hemisphere, in which linguistic functions primarily operate, tends to break down these meta-objects and perceive them separately, whereas the right hemisphere tends to notice mostly the overall silhouette of the meta-object. Thus when a still-life painting of a pile of objects that together resemble a face is presented to the right (relatively non-linguistic) hemisphere, a face is perceived, not a bunch of objects (that happen to be organized in a face-resembling pattern).</p>

<p>This sort of evidence might offer the next-best thing to what you'd hope to find through study of visual agnosia. From Gazzaniga's demonstrations with his split-brain case study subject, it seems likely that, without involving the left hemisphere (and thus largely avoiding the involvement of major linguistic processes), the right hemisphere operating alone would perceive a fork on a cutting board as one object in the shape of a cutting board, or would at least require stronger visual contrasts between the two (e.g., color, shadow, texture) to achieve a <a href="https://en.wikipedia.org/wiki/Just-noticeable_difference" rel="nofollow noreferrer">just-noticeable difference</a> between the two, relative to the left hemisphere operating without the right. Whether that actually has anything to do with language though, or whether it's a separate qualitative difference in the functions of each hemisphere's visual processes, is another question on which I can hardly even begin to speculate.</p>

<p>Yes, I do think thinking without language is possible. A pretty simple example is the word 'perceive'. A person may perceive a lot many phenomena even if s/he doesn't know how to put it in words.</p>

<p>To me Leonardo Da Vinci seems to be a great thinker who used to think without language, evident by his ability to develop a fly-able sketch without accompanying language of aviation. This is to be understood in the context that every field of specialty has its own language and even then time and again there are prodigies who deny this language and add value to the specialty. If logic and proof is the language of Mathematics then Srinivas Ramanujan thought without that language thereby finding it difficult to provide proofs to his formulas and theorems.</p>

<p>Language is basically a digitised construct of an analogous world. If one were to think based only on words , s/he might never be able to perceive the reality of the world. This is evident in Einstein's statement, “Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.” Here, Einstein might be seen referring to knowledge as known by language and words and imagination as an ability to think beyond these words. Einstein's inability or blessing to have not been able to speak till age of seven ( Edit: <a href="http://www.albert-einstein.org/article_handicap.html" rel="nofollow noreferrer">http://www.albert-einstein.org/article_handicap.html</a> ) might be reason behind his 'superpower' to look beyond words.</p>

<p>To cite a more orientalist example, Indian meditative sages are supposed to have pretty sharp contemplative skills using mediation. (Edit : <a href="http://newsroom.ucla.edu/releases/evidence-builds-that-meditation-230237" rel="nofollow noreferrer">http://newsroom.ucla.edu/releases/evidence-builds-that-meditation-230237</a> ) As a personal experience, which most Indians can relate to, meditating on a situation is much more helpful than trying to fit it into the maze of language. ( Edit : can't cite a study to showcase experiences of people around me, but to me more precise I have had many teachers who would tell us to just meditate over a new concept if the words are enough, and it has helped many students including me)</p>

<p>Yes, Thinking without language is possible. Suppose a well-known boy "Mogli" who was left alone in jungle before he could learn language from his parents. But still he could manage to live many years in jungle till he met other humans. Mogli may be a fictional character but story is based on real incidence and much this kind of cases has been recorded. </p>

<p>My point is, in absence of language the jungle boy was able to learn things, think which is good and bad. Make strategies and learned how to use objects. His learning was beyond natural instincts. Without thought or cognitive processes it would not be possible to live throughout these many years. When these kinds of kids are adopted again by humans they learned how to use their vocal cords, modulate voices, and understand gestures. During this learning they think and finally they learn to use language to express their thoughts.</p>

For a person with a visual agnosia I wonder this: if two unrecognizable objects are shown to them, and one is entirely within the background of the other, (say a fork on a cutting board) do these two objects mold into a single unrecognizable object or do they remain distinct unrecognizable objects? Or have I got it all wrong and they don't even "see" any object to speak of (regardless of how many or how they are positioned)?</p>

It all depends on how you define "language" and "thought". The way I define them (very broadly, really universally), neither can exist without the other.

Language is a component of thought, while thought produces language. Language and thought are so inter-dependent as to be virtually the same thing.

And at the social level, thought and language are commutative, so that at times one's language may serve to provoke others to think, while at other times one's thoughts may motivate one to express them in language, for purposes of communicating or sharing with others. And vice-versa.

Language and thought are also commutative on the personal, individual level, in that they help bridge the barriers between internal and external realities.

Perceptions on the other hand, are the mechanisms through which we gain the awareness we need to form thoughts and language. Neither thoughts nor language are possible without the ability to perceive on some level.

So in the order of primacy:

1. Perception or sense
2. Awareness (consciousness)
3. Generic Ideas and language, often equally irrational
4. Reasoned logic and logical language (with increasing complexity)
5. Sound judgment or wisdom, and the ability to use language for good purposes (most complex)

I say "primacy" for this list, because *perception* (or sense) is the foundation for all thought and language, at any level. People can and often do compensate for losses of perceptual ability.

Certainly.

It depends on the type of learning process of a person. One can be better at remembering images, so he might access the images first when trying to define an object/event/etc. This can be thought of as having a [photographic memory](http://en.wikipedia.org/wiki/Eidetic_memory).

Developing (with time or by injury) agnosia or aphasia at some point in your life would certainly mess your usual way of processing information; and it would be very hard to rebuild a new recognition system as old habits are hard to break.

On another note, some friend of mine claims that he consciously thinks with noises when playing and writing music.

It is hard to imagine what evidence might be found of thoughts existing without language. Even [feral children](https://en.wikipedia.org/wiki/Feral_child) encounter language (either verbal or nonverbal) through limited contact with people or animals, and lab animals communicate nonverbally with researchers, even if only through their environments (the researcher observes the animal's behavior, and the animal observes how the researcher changes its environment, e.g., its food, waste, and cage furnishings). For reasons such as these, the prospect of thought without language may be somewhat untestable. Producing a sentient being that is never allowed the opportunity to communicate with others would also be unethical by most means I can imagine.

As for your (largely unrelated) question about object discrimination in the absence of recognition, I can't offer any insight in the context of visual agnosia per se, other than to point out that (according to [Wikipedia](https://en.wikipedia.org/wiki/Visual_agnosia)), "Visual agnosia...is not due to a deficit in...language." However, outside that context, I would recommend watching [an episode of Scientific American Frontiers, "The Man with Two Brains"](http://youtu.be/lfGwsAdS9Dc) that I mentioned in [another answer of mine](https://cogsci.stackexchange.com/a/5459/4086) just yesterday! The effects of lacking communication between one's cerebral hemispheres are different from visual agnosia, but give some insight into how unknown objects (e.g., crude drawings) may be identified and differentiated in the absence of linguistic function, which is generally left-hemisphere-dominant. In this episode, Mike Gazzaniga also demonstrates how his split-brain case study subject attends differently to the components that comprise larger objects vs. the overall unity of those objects as one *meta-object* (coined here for lack of a better term), depending on which hemisphere's visual field processes such an object comprised of smaller objects. The left hemisphere, in which linguistic functions primarily operate, tends to break down these meta-objects and perceive them separately, whereas the right hemisphere tends to notice mostly the overall silhouette of the meta-object. Thus when a still-life painting of a pile of objects that together resemble a face is presented to the right (relatively non-linguistic) hemisphere, a face is perceived, not a bunch of objects (that happen to be organized in a face-resembling pattern).

This sort of evidence might offer the next-best thing to what you'd hope to find through study of visual agnosia. From Gazzaniga's demonstrations with his split-brain case study subject, it seems likely that, without involving the left hemisphere (and thus largely avoiding the involvement of major linguistic processes), the right hemisphere operating alone would perceive a fork on a cutting board as one object in the shape of a cutting board, or would at least require stronger visual contrasts between the two (e.g., color, shadow, texture) to achieve a [just-noticeable difference](https://en.wikipedia.org/wiki/Just-noticeable_difference) between the two, relative to the left hemisphere operating without the right. Whether that actually has anything to do with language though, or whether it's a separate qualitative difference in the functions of each hemisphere's visual processes, is another question on which I can hardly even begin to speculate.

Yes, I do think thinking without language is possible. A pretty simple example is the word 'perceive'. A person may perceive a lot many phenomena even if s/he doesn't know how to put it in words.

To me Leonardo Da Vinci seems to be a great thinker who used to think without language, evident by his ability to develop a fly-able sketch without accompanying language of aviation. This is to be understood in the context that every field of specialty has its own language and even then time and again there are prodigies who deny this language and add username_0ue to the specialty. If logic and proof is the language of Mathematics then Srinivas Ramanujan thought without that language thereby finding it difficult to provide proofs to his formulas and theorems.

Language is basically a digitised construct of an analogous world. If one were to think based only on words , s/he might never be able to perceive the reality of the world. This is evident in Einstein's statement, “Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.” Here, Einstein might be seen referring to knowledge as known by language and words and imagination as an ability to think beyond these words. Einstein's inability or blessing to have not been able to speak till age of seven ( Edit: <http://www.albert-einstein.org/article_handicap.html> ) might be reason behind his 'superpower' to look beyond words.

To cite a more orientalist example, Indian meditative sages are supposed to have pretty sharp contemplative skills using mediation. (Edit : <http://newsroom.ucla.edu/releases/evidence-builds-that-meditation-230237> ) As a personal experience, which most Indians can relate to, meditating on a situation is much more helpful than trying to fit it into the maze of language. ( Edit : can't cite a study to showcase experiences of people around me, but to me more precise I have had many teachers who would tell us to just meditate over a new concept if the words are enough, and it has helped many students including me)

Yes, Thinking without language is possible. Suppose a well-known boy "Mogli" who was left alone in jungle before he could learn language from his parents. But still he could manage to live many years in jungle till he met other humans. Mogli may be a fictional character but story is based on real incidence and much this kind of cases has been recorded.

My point is, in absence of language the jungle boy was able to learn things, think which is good and bad. Make strategies and learned how to use objects. His learning was beyond natural instincts. Without thought or cognitive processes it would not be possible to live throughout these many years. When these kinds of kids are adopted again by humans they learned how to use their vocal cords, modulate voices, and understand gestures. During this learning they think and finally they learn to use language to express their thoughts.
