Some metaphors are common in spoken language but are inappropriate in sign, body-part metaphors are possible in sign metaphors but odd/uncommon in spoken metaphor. In spoken language, tone and body position determine when a metaphor is that and not literal. Sign metaphors also have similar markers such as change in facial expression but are more limited in expressing change in tone and body position (as the body is already the main mode of communication). There is a sign for "metaphor" or a way to slightly change the signs for common words in metaphor so that the "listener" knows that the "speaker" means something metaphorically as opposed to literally.

By Paul H. Thibodeau and Lera Boroditsky "In five experiments, we have explored how these metaphors influence the way that we reason about complex issues and forage for further information about them. We find that metaphors can have a powerful influence over how people attempt to solve complex problems and how they gather more information to make "well-informed" decisions.... [D]ifferent metaphorical frames created differences in opinion as big or bigger than those between Democrats and Republicans."

When people talk about positive and negative emotions they often use spatial metaphors. A happy person is on top of the world, but a sad person is down in the dumps. Some researchers believe these metaphors are a clue to the way people understand emotions: not only do we use spatial words to talk about emotional states, we also use spatial concepts to think about them. Researchers Daniel Casasanto (MPI and Donders Institute, Nijmegen) and Katinka Dijkstra (Erasmus University, Rotterdam) ran 2 experiments. In the first experiment, students had to move glass marbles upward or downward into one of two cardboard boxes, with both hands simultaneously, timed by a metronome. Meanwhile, they had to recount autobiographical memories with either positive or negative emotional valence, like "Tell me about a time when you felt proud of yourself', or 'a time when you felt ashamed of yourself.' Moving marbles upward caused participants to remember more positive life experiences, and moving them downward to remember more negative experiences. Memory retrieval was most efficient when participants' motions matched the spatial directions that metaphors in language associate with positive and negative emotions. The second experiment tested whether seemingly meaningless motor actions, e.g. moving marbles up or down, could influence the content of people's memories. Participants were given neutral-valence prompts, like "Tell me about something that happened during high school," so they could choose to retell something happy or sad. Their choices were determined, in part, by the direction in which they were assigned to move marbles. Moving marbles upward encouraged students to recount positive high school experiences like "winning an award," but moving them downward to recall negative experiences like "failing a test." "These data suggest that spatial metaphors for emotion aren't just in language," Casasanto says, "linguistic metaphors correspond to mental metaphors, and activati

New study co-authored by Lera Boroditsky: "The way we talk about complex and abstract ideas is suffused with metaphor. In five experiments...we find that metaphors can have a powerful influence over how people attempt to solve complex problems and how they gather more information to make "well-informed" decisions."

Excellent, brief article on the power of metaphor to change people's minds. Also gives a kind of algebraic formula for inventing metaphors.

(This article was by my college friend, Quinn Eastman, who's a trained scientist and science writer for Emory University.) Listening to metaphors involving arms or legs loops in a region of the brain responsible for visual perception of those body parts, scientists have discovered. The finding, recently published in Brain & Language, is another example of how neuroscience studies are providing evidence for "grounded cognition" - the idea that comprehension of abstract concepts in the brain is built upon concrete experiences, a proposal whose history extends back millennia to Aristotle. When study participants heard sentences that included phrases such as "shoulder responsibility," "foot the bill" or "twist my arm", they tended to engage a region of the brain called the left extrastriate body area or EBA. The same level of activation was not seen when participants heard literal sentences containing phrases with a similar meaning, such as "take responsibility" or "pay the bill." The study included 12 right-handed, English-speaking people, and blood flow in their brains was monitored by functional MRI (magnetic resonance imaging). "The EBA is part of the extrastriate visual cortex, and it was known to be involved in identifying body parts," says senior author Krish Sathian, MD, PhD, professor of neurology, rehabilitation medicine, and psychology at Emory University. "We found that the metaphor selectivity of the EBA matches its visual selectivity." The EBA was not activated when study participants heard literal, non-metaphorical sentences describing body parts. "This suggests that deep semantic processing is needed to recruit the EBA, over and above routine use of the words for body parts," Sathian says. Sathian's research team had previously observed that metaphors involving the sense of touch, such as "a rough day", activate a region of the brain important for sensing texture. In addition, other researchers have shown t

New research in a Princeton University and the Free University of Berlin report shows that taste-related words actually engage the emotional centers of the brain more than literal words with the same meaning. sentences containing words that invoked taste activated areas known to be associated with emotional processing, such as the amygdala, as well as the areas known as the gustatory cortices that allow for the physical act of tasting. Interestingly, the metaphorical and literal words only resulted in brain activity related to emotion when part of a sentence, but stimulated the gustatory cortices both in sentences and as stand-alone words. Metaphorical sentences may spark increased brain activity in emotion-related regions because they allude to physical experiences, said co-author Adele Goldberg, a Princeton professor of linguistics in the Council of the Humanities. Human language frequently uses physical sensations or objects to refer to abstract domains such as time, understanding or emotion, Goldberg said. "You begin to realize when you look at metaphors how common they are in helping us understand abstract domains," Goldberg said. "It could be that we are more engaged with abstract concepts when we use metaphorical language that ties into physical experiences."

This article explains what a metaphor is and why metaphors are important. In this article you learn about how metaphors can be very effective in communicating tangible and abstract information. Tips and examples for making effective metaphors are also given in this article. For example, visual words are most effective when communicating.

Working on the metaphor poems lead me to wonder why metaphors are so important to communication and emotional connection. This article explains why metaphors have a different affect than other types of communication.

"A small research arm of the U.S. government's intelligence establishment wants to understand how speakers of Farsi, Russian, English, and Spanish see the world by building software that automatically evaluates their use of metaphors."

"We can't talk about any complex situation-like crime-without using metaphors," says Lera Boroditsky, assistant professor of psychology.... In one study, 71 percent of the participants called for more enforcement when they read: "Crime is a beast ravaging the city of Addison." That number dropped to 54 percent among participants who read an alternative framing: "Crime is a virus ravaging the city of Addison."

Because of the role they play in our thought processes, the metaphors we choose to use can dramatically impact people's perceptions in ways that have real-world consequences. Metaphors may also reinforce culturally-ingrained stereotypes.

Researchers found that people tend to rate discoveries that came about "like a light bulb" as more exceptional than those that are "nurtured like seeds." These two metaphors are often used to describe scientific discovery and what we perceive as genius. Along with them come ingrained, subconscious associations that may have unintended consequences, according to a study published Friday in Social Psychological and Personality Science. Also, those metaphors had different effects depending on the gender of the idea's creator.

Metaphors are extremely useful things. They provide a common language-an agreed-upon shorthand-for truths that can be difficult to discuss in terms that are simultaneously broad and precise. It doesn't take a Lakoff or a Luntz to appreciate the power of shared metonyms, particularly as the country grapples with the results of an election that was a political embodiment of that well-worn Fitzgerald line: "The test of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function." This election, in particular, featured many more than two oppositional ideas. The 2018 midterms were about voter suppression, which is also to say about robbing swaths of Americans of their constitutional rights, which is also to say about structuralized inequality. They were about enfranchisement and its opposite. They were about progress. They were about backlash. They were about women winning. They were about women losing. They were about compassion empowered, and racism rewarded, and hard work realized, and cruelty weaponized, and corruption unpunished. They were about hatred. They were about love. They were about history made. They were about history ignored. They were about American exceptionalism in the best sense and-at the same time-in the worst. How do you sum that up in a headline or a news article? How do you talk about it in neatly cable-newsed sound bites? The true answer is that you can't, and the even truer answer is that this is why it is necessary to have a flourishing and extremely diverse media ecosystem, so that a broadly coherent picture might emerge from the individual efforts-but the more practical and immediate answer is that you can try to use metaphors to summarize the situation. You can talk about waves, with their familiarity and their liquidity and their visual power, and you can talk about the color of your notional water, and the size and shape of the swell, and you

New brain imaging research at Emory University reveals that a region of the brain important for sensing texture through touch, the parietal operculum, is also activated when someone listens to a sentence with a textural metaphor. The same region is not activated when a similar sentence expressing the meaning of the metaphor is heard.

This article connects the use of metaphor and language throughout the election, and how metaphors are often the phrases we remember throughout an election.

According to research led by V. S. Ramachandran, director of the Center for Brain and Cognition at the University of California, San Diego, a region of the brain known as the angular gyrus is probably at least partly responsible for the human ability to understand metaphor. Ramachandran and colleagues tested four right-handed patients with damage to the left angular gyrus. Fluent in English and otherwise intelligent and mentally lucid, the patients showed gross deficits in comprehending such common proverbs as "the grass is always greener on the other side" and "an empty vessel makes more noise." Asked to explain the sayings, the patients tended give responses that were literal. The metaphorical meaning escaped them almost entirely.

This article discusses how the brain responds when hearing textural metaphors and literal sentences.
