Definition

Embodied cognition claims that an organism’s sensorimotor capacities (ability of the body to respond to its senses with movement), body and environment not only play an important role in cognition, but the manner in which a person’s body and their surroundings interacts allows for specific brain functions to develop and in the future to be able to act. (website link). This means that not only does the mind influence the body’s movements, but the body also influences the abilities of the mind. There are three generalizations that are assumed to be true relating to embodied cognition. A person's motor system (that controls movement of the body) is activated when (1) they observe manipulable objects, (2) process action verbs, and (3) observe another individual's movements (Mahon).

In order to create movement of the body, a person usually thinks (or the brain subconsciously functions) about the movement it would like to accomplish. Embodied language processing asserts that there can also be an opposite influence. This means that moving your body in a certain way will impact how you comprehend, as well as process, language - whether it is an individual word or a complete phrase or sentence. Embodied language processing suggests that the brain resources that are used for perception, action, and emotion are also used during language comprehension (Rueschemeyer). Studies have found that participants are faster at comprehending a sentence when the picture that goes along with it matches the actions described in the sentence (Zwann 2). Action and language about action have been found to be connected because the areas of the brain that control them overlap (Rueschemeyer).

Theories

Some research has claimed that simulating emotions can play an important role in understanding and processing language. In one study, the researchers measured the time needed for a person to comprehend a sentence written with an implied emotion while they were in either a matching or opposite emotional state. The participants who were forced to smile responded with higher humor ratings of cartoons than participants who read these cartoons while frowning. These researchers also found that pleasant sentences were read faster when participants were smiling than when they were frowning. Unpleasant sentences were read slower when participants were smiling than when frowning. These results demonstrate that emotional cues created by the body help in language comprehension. Further research has shown that the same areas in the brain that process emotions also function during language comprehension that has an emotional connection (Havas & Glenberg).

Other research has shown that words with a positive connotation, for example: love, are identified faster when the identification process includes an approach action (flexing an arm) than when the action is a withdrawal action (arm extension) (Havas & Glenberg).

Emotional stimulation affects language comprehension within a sentence or a phrase, but has not been shown to facilitate language comprehension on a single word basis. Whereas a person's motor (action) system influences understanding for both individual word as well as entire sentences (Havas & Glenberg).

Experiential Trace Hypothesis

Experiential Trace Hypothesis states that each time we interact with the world, traces of that experience are left in our brain (Zwann). These traces can be accessed again when thinking of words or sentences that relate to that experience. Additionally, these traces in our brain are linked to the action that they are associated with (Zwann). Words and sentences become those cues that retrieve these traces from our mind. Researchers have studied if the previous experience with a word (such as its location in vertical space) affects how people understand and then respond to that word (Lachmair). In one experiment, researchers hypothesized that if reading an object noun also activates a location that is linked to that noun, then the following action response should be compatible with that association (Lachmair). They found that participants were faster to push a button higher up when the word was associated with being "up" or "above" than when the button was lower for words associated with "up" and "above". The results of this study displayed that participants were faster to respond when the location of the word and the action they had to perform were compatible. This demonstrates that language processing and action are connected. This research also found that the location information of a word is automatically activated after seeing the word (Lachmair). In a similar study, it was discovered that participants were equally as fast at responding to words that were associated with either an upward or downward location when the buttons to respond to these words were horizontal - meaning that the experiential trace effect was ruled out when the responding action did not link to either of the locations that were activated (Zwann 2).

Word Activation

One theory by researchers is that when a person processed different words, the location of those words is also called to mind based on past experience with those words. For example, if a person thinks about an airplane, they also think about the sky and the direction "up". Whereas, if a person thinks about the word snail, they also think about the ground and the downward direction. There is research that provides evidence that previous experiences with words will affect how they are processed. As a result, movement associated with these words is also automatically processed simultaneously when these words are being processed. These action words (such as, jump) produce greater activity levels in the brain than abstract verbs (for example, feel) (Rueschemeyer).

Schemas

Language comprehension involves three processes that overlap. First, words and phrases are associated with certain objects in the environment or perceived symbols. Secondly, a person must determine how they can interact with the objects; these are called affordances. For example, a chair affords sitting for a human, but not for a tree. Or a pen affords writing for a human but not for a hamster. And finally, a person must look at the different parts of the sentence to determine how the affordances combine in order to accomplish a goal. This process is called the Indexical Hypothesis.

To summarize this hypothesis, an understanding of language results from a simulation of the actions that are implied by the meaning of the sentence. Put more simply, meaning is based on action (Glenberg & Kaschak).

Actions can also influence a person's reaction time even when it doesn't make sense with the actual meaning of the sentence. A study conducted asked participants to perform a list of actions. They were then asked to make judgments if a sentence was logical or not. Participants were faster to respond that a sentence was logical if they had performed that action previously. For example, participants were faster to determine that the metaphorical phrase "toss out some ideas" was a logical phrase after they had performed a tossing motion, even though you can't literally toss a plan (Gibbs). — Preceding unsigned comment added by Lino08 (talk • contribs) 05:51, 12 April 2012 (UTC)

Action-Sentence Compatibility Effect (ACE)

Sentence processing can activate motor neurons based on the actions referred to in the sentence. In one study, researchers asked participants to make judgments on whether a sentence was sensible or not. For example, "You handed Courtney the notebook" versus "Courtney handed you the notebook". They asked participants in one condition to push a button farther away from their body if the sentence was sensible and a button close to their body when it wasn't sensible and they switched the meaning of these two buttons in the other condition. The results of this study demonstrated that participants were faster at pushing the button that was sensible when the action in the sentence coincided with the action required by them to push the correct button (Havas & Glenberg). The depicted motion in these sentences affected the amount of time required to understand the sentences that described the motion that is in the same direction. This effect has been shown to apply to sentences that describe concrete actions (putting a book on a shelf) as well as more abstract actions (you told the story to the policeman) (Glenberg & Kaschak). The Action-Compatibility Effect also states that the brain resources used to plan and carry out actions are also used in language comprehension; therefore, if an action implied in a sentence is different than the suggested response, there is interference within these brain resources (Glenberg & Kaschak).

Another study demonstrated that the areas in people's brains that control a person's leg are activated even when just reading the word "kick". The areas in their brains related to hands were activated when reading the word "pick". This study provides further evidence that motor areas in the brain linked to motion are also activated when processing words and sentences related to that motion (Havas & Glenberg).

Actions emphasize meaning

Many studies have shown how body movements and speech can be combined to emphasize meaning. A person can observe the actions of another to help them comprehend what that person is saying (Gibbs). For example, if a person is pointing repeatedly, it helps the listener to understand that the direction being inferred is very important; whereas if it was a casual point in the general direction, the location of the object may not be as necessary to comprehend what the speaker is saying. Another example may be the stomping of one’s foot. This can help the listener to understand the anger and frustration being conveyed by the speaker.

Implications

Many studies have demonstrated that people’s understanding of words and sentences can influence their movements and actions as well as the opposite – peoples’ actions can influence how quickly they can comprehend a word or sentence. This knowledge is important for many reasons. People who are in occupations that have to make split second decisions based on commands (such as people in the military) will be much faster at responding correctly when the type of action that is required of them matches how they process the meaning of that action in the command. Embodied language processing can also be important in understanding how to teach language to children. Children are much more apt to comprehend words and sentences when the motor system in their brain is activated and they can make a connection between the word or sentence and its corresponding action.

Review

• I really like where this article is going so far! I was aware of some of the concepts before, but I didn't know what things were called and you were able to expand my knowledge of the topic - good!
• You did a good job of putting things into different sections which really helped with clarity.
• You don't have a lead section yet, but it might be easier to write once you have the rest of your information solidified. Search "WP:LEAD" to find a page that has more information about how to write the lead section.
• You'll have to add in your references, but you know that already.
• In the Definition and Schemas paragraphs you used the word "you." This might be okay, but usually we try to avoid using this word in formal writing. It sounds okay to me, but it might be more formal if you rephrased those sentences.
• All in all, it's looking really good so far. It will really come together once you start adding references, linking to other Wikipedia pages and adding your lead paragraph.
