Towards a metaphorical biology

The metaphorical nature of biological language is examined and the use of metaphors for providing the linguistic context in which similarities and differences are made is described. Certain pervasive metaphors which are characterised by systemic properties are noted, and in order to provide some focus to the study, systemic metaphors associated with machine, text and organism are discussed. Other systemic metaphors such as society and circuit are also reported. Some details concerning interrelations between automaton and organism are presented in the light of the previous discussion.An approach towards the analysis of biosystem metaphors is outlined which relates part-whole, organisational level and systemic metaphors in a single model. Examples are provided throughout the discussion and mainly come from computing. The potential for metaphorical transfers between these domains is considered.     

Metaphor Identification in Large Texts Corpora

Identifying metaphorical language-use (e.g., sweet child) is one of the challenges facing natural language processing. This paper describes three novel algorithms for automatic metaphor identification. The algorithms are variations of the same core algorithm. We evaluate the algorithms on two corpora of Reuters and the New York Times articles. The paper presents the most comprehensive study of metaphor identification in terms of scope of metaphorical phrases and annotated corpora size. Algorithms’ performance in identifying linguistic phrases as metaphorical or literal has been compared to human judgment. Overall, the algorithms outperform the state-of-the-art algorithm with 71% precision and 27% averaged improvement in prediction over the base-rate of metaphors in the corpus.     

Genomics: shifts in metaphorical landscape between 2000 and 2003

This article examines the shifts and changes in the metaphors used to describe the human genome and the human genome project (HGP) between 2000 and 2003, with the year 2001 as a trigger for genomic and metaphorical reflection. We want to answer questions, such as: Did the findings announced in 2001 shake the metaphorical foundations on which the HGP had been built or not? Did novel metaphors capture the imagination of scientists and the public or did old metaphors survive throughout this period? What influence does the continuity or discontinuity in metaphorical framing of the HGP have on the public perception of the HGP as well as on its scientific understanding? To answer these questions we have systematically compared the metaphors used in one major scientific journal, Nature, and in one major UK newspaper, the online edition of the Guardian/The Observer during a period of two months around June 2000, February 2001 and April 2003.     

Untying the Gordian knot of creation: metaphors for the Human Genome Project in Greek newspapers

This article studies the metaphorical expressions used by newspapers to present the near completion of the Human Genome Project (HGP) to the Greek public in the year 2000. The analysis, based on cognitive metaphor theory, deals with the most frequent or captivating metaphors used to refer to the human genome, which give rise to both conventional and novel expressions. The majority of creative metaphorical expressions participate in the discourse of hope and promise propagated by the Greek media in an attempt to present the HGP and its outcome in a favorable light. Instances of the competing discourse of fear and danger are much rarer but can also be found in creative metaphorical expressions. Metaphors pertaining to the Greek culture or to ancient Greek mythology tend to carry a special rhetorical force. However, it will be shown that the Greek press strategically used most of the metaphors that circulated globally at the time, not only culture specific ones.     

The conditional relationship between English language proficiency and earnings among US immigrants

Using the 2000 US census data for immigrants of twenty language groups resided in metropolitan areas, we test the hypothesis that the rate of returns (in earnings) to English proficiency is not constant but varies with the language environment (as defined by group size, segregation, linguistic heterogeneity and inequality) in which immigrants are embedded. Results from our hierarchical model indicate that while an increase in the size and segregation of the language group diminishes returns to English proficiency, a rise in linguistic heterogeneity and inequality in the metropolitan area has the opposite effects. This study expands the scope of the previous studies by identifying conditions under which returns to English proficiency among immigrants are modified by a set of contextual factors often overlooked.     

Metaphors we think with: the role of metaphor in reasoning

The way we talk about complex and abstract ideas is suffused with metaphor. In five experiments, we explore how these metaphors influence the way that we reason about complex issues and forage for further information about them. We find that even the subtlest instantiation of a metaphor (via a single word) can have a powerful influence over how people attempt to solve social problems like crime and how they gather information to make "well-informed" decisions. Interestingly, we find that the influence of the metaphorical framing effect is covert: people do not recognize metaphors as influential in their decisions; instead they point to more "substantive" (often numerical) information as the motivation for their problem-solving decision. Metaphors in language appear to instantiate frame-consistent knowledge structures and invite structurally consistent inferences. Far from being mere rhetorical flourishes, metaphors have profound influences on how we conceptualize and act with respect to important societal issues. We find that exposure to even a single metaphor can induce substantial differences in opinion about how to solve social problems: differences that are larger, for example, than pre-existing differences in opinion between Democrats and Republicans.     

“This will clear your mind”: The use of metaphors for medication in psychiatric settings

Psychiatric medications are an important part of the interaction between patients and clinicians in psychiatric settings. This article examines metaphors used by patients and clinicians to talk about the effects of antipsychotic medication. Metaphors provide a way to communicate about issues of identity and change involved in giving and taking medication. Although metaphorical language can contribute to misunderstandings between patients and clinicians, metaphor is also a major way in which clinical experiences are given shared meanings.     

Speech rhythm: a metaphor?

Is speech rhythmic? In the absence of evidence for a traditional view that languages strive to coordinate either syllables or stress-feet with regular time intervals, we consider the alternative that languages exhibit contrastive rhythm subsisting merely in the alternation of stronger and weaker elements. This is initially plausible, particularly for languages with a steep ‘prominence gradient’, i.e. a large disparity between stronger and weaker elements; but we point out that alternation is poorly achieved even by a ‘stress-timed’ language such as English, and, historically, languages have conspicuously failed to adopt simple phonological remedies that would ensure alternation. Languages seem more concerned to allow ‘syntagmatic contrast’ between successive units and to use durational effects to support linguistic functions than to facilitate rhythm. Furthermore, some languages (e.g. Tamil, Korean) lack the lexical prominence which would most straightforwardly underpin prominence of alternation. We conclude that speech is not incontestibly rhythmic, and may even be antirhythmic. However, its linguistic structure and patterning allow the metaphorical extension of rhythm in varying degrees and in different ways depending on the language, and it is this analogical process which allows speech to be matched to external rhythms.     

Traces of cannibalistic instinct in food denomination

Drawing attention to the associations evoked in the process of food denomination, the paper attempts to reveal the traces of cannibalistic instinct in this realm. By singling out some of the principal ways used in the semantic reticulum to name food, special attention is devoted to those names that allude to particular categories of enemies (devoured as wholes or as parts of the body). What is referred to as "anti-taboo" shows how the linguistic and more generally the anthropological 'substitution process' is a human reaction to the persistence of the cannibalistic taboo in the face of the belief that cannibalism is an impulse far removed from modern society. Finally it is noted that cannibalistic metaphors have been analysed in other fields, whereas in the area of food denomination they have been neglected. The suggestion is that the reason for such neglect may lie in an attempt to conceal our closeness to the cannibalistic instinct in the form of linguistic substitution.     

Prediction of psychosis across protocols and risk cohorts using automated language analysis

Language and speech are the primary source of data for psychiatrists to diagnose and treat mental disorders. In psychosis, the very structure of language can be disturbed, including semantic coherence (e.g., derailment and tangentiality) and syntactic complexity (e.g., concreteness). Subtle disturbances in language are evident in schizophrenia even prior to first psychosis onset, during prodromal stages. Using computer‐based natural language processing analyses, we previously showed that, among English‐speaking clinical (e.g., ultra) high‐risk youths, baseline reduction in semantic coherence (the flow of meaning in speech) and in syntactic complexity could predict subsequent psychosis onset with high accuracy. Herein, we aimed to cross‐validate these automated linguistic analytic methods in a second larger risk cohort, also English‐speaking, and to discriminate speech in psychosis from normal speech. We identified an automated machine‐learning speech classifier – comprising decreased semantic coherence, greater variance in that coherence, and reduced usage of possessive pronouns – that had an 83% accuracy in predicting psychosis onset (intra‐protocol), a cross‐validated accuracy of 79% of psychosis onset prediction in the original risk cohort (cross‐protocol), and a 72% accuracy in discriminating the speech of recent‐onset psychosis patients from that of healthy individuals. The classifier was highly correlated with previously identified manual linguistic predictors. Our findings support the utility and validity of automated natural language processing methods to characterize disturbances in semantics and syntax across stages of psychotic disorder. The next steps will be to apply these methods in larger risk cohorts to further test reproducibility, also in languages other than English, and identify sources of variability. This technology has the potential to improve prediction of psychosis outcome among at‐risk youths and identify linguistic targets for remediation and preventive intervention. More broadly, automated linguistic analysis can be a powerful tool for diagnosis and treatment across neuropsychiatry.     

Linguistic Magic Bullets in the Making of a Modernist Anthropology

This article engages current debates about concepts of culture in U.S. anthropology by examining how assumptions about language shape them. Characterizing linguistic patterns as particularly inaccessible to conscious introspection, Franz Boas suggested that culture is similarly automatic and unconscious—except for anthropologists. He used this notion in attempting to position the discipline as the obligatory passage point for academic and public debate about difference. Unfortunately, this mode of inserting linguistics in the discipline, which has long outlived Boas, reifies language ideologies by promoting simplistic models that belie the cultural complexity of human communication. By pointing to the way that recent work in linguistic anthropology has questioned key assumptions that shaped Boas's concept of culture, the article urges other anthropologists to stop asking their linguistic colleagues for magic bullets and to appreciate the critical role that examining linguistic ideologies and practices can play in discussions of the politics of culture.

Natural Language Metaphors Covertly Influence Reasoning

Metaphors pervade discussions of social issues like climate change, the economy, and crime. We ask how natural language metaphors shape the way people reason about such social issues. In previous work, we showed that describing crime metaphorically as a beast or a virus, led people to generate different solutions to a city’s crime problem. In the current series of studies, instead of asking people to generate a solution on their own, we provided them with a selection of possible solutions and asked them to choose the best ones. We found that metaphors influenced people’s reasoning even when they had a set of options available to compare and select among. These findings suggest that metaphors can influence not just what solution comes to mind first, but also which solution people think is best, even when given the opportunity to explicitly compare alternatives. Further, we tested whether participants were aware of the metaphor. We found that very few participants thought the metaphor played an important part in their decision. Further, participants who had no explicit memory of the metaphor were just as much affected by the metaphor as participants who were able to remember the metaphorical frame. These findings suggest that metaphors can act covertly in reasoning. Finally, we examined the role of political affiliation on reasoning about crime. The results confirm our previous findings that Republicans are more likely to generate enforcement and punishment solutions for dealing with crime, and are less swayed by metaphor than are Democrats or Independents.     

Language choices in the teaching of human reproduction

The choice of which language strategies to use in schools in Africa is the subject of much debate. In the Life Sciences, cultural issues associated with the use of biological terminology add to this debate. In our study, we examined the language choices made by Grade 7 Natural Sciences teachers in South Africa during their teaching of human reproduction. A mixed method approach was employed, involving firstly a survey questionnaire amongst 40 teachers in urban schools followed by a multiple case study of 10 of these teachers. Data were collected during classroom observations by means of field notes and audio-recordings followed by interviews which were transcribed and coded. We found that teachers used a variety of language strategies including use of home languages, English or code switching. The teacher’s and/or learners’ fluency in English and the teacher’s perception of the need for learners to feel at ease when discussing human reproduction influenced their choices. In addition, teachers’ belief in the importance of using biological terminology rather than traditional metaphors in order to create a more formal and thus respectful discourse, led them to use the English version of the biological terms. We argue that different language choices are appropriate for different urban contexts, and that teachers should use the language/s in which learners are most comfortable in order to enable deep and rich discussions on the sensitive subject of human reproduction.     

Language and Culture on the North Coast of New Guinea

Statistical analysis of variability in assemblages of material culture obtained at different villages on the North Coast of New Guinea indicates that similarities and differences among these assemblages are most strongly associated with geographic propinquity, irrespective of linguistic affinities. When assemblage similarity is adjusted for the effect of distance, diversity in material culture appears unrelated to the linguistic relationships of these communities. This study shows that similarity in material culture assemblages can mask marked heterogeneity in language. Language, however, is frequently used to index people in Melanesia on the assumption that language is a useful key to their other human characteristics. This analysis does not lend support to this common practice, and it has implications for how prehistoric cultural complexes in Melanesia are defined and interpreted.     

Zombie Linguistics: Experts,Endangered Languages and the Curse of Undead Voices

The alarming projection that up to ninety per cent of the world's languages will become extinct by the end of this century has prompted a new sense of urgency among linguists and other language scholars to rush out and record the last utterances from the last speakers of ‘endangered languages’. As the last speaker utters her/his last words, the ‘expert’ is there to record this important moment and preserve it for all time. Among the benefits from such preservation efforts is the ability to play back the recordings at any time in any place. In popular media this process is described as ‘saving the language’ through recording and documentation. Unfortunately, these recordings are not living voices. Rather, they are zombie voices—undead voices that are disembodied and techno-mechanized. They are cursed with being neither dead nor alive. They become artefacts of technological interventions, as well as expert valorisations of linguistic codes. Expert rhetoric compounds the problem by the use of metaphoric frames such as death, endangerment and extinction. Metaphors not only frame discourses of language endangerment, but they also frame and influence actions and interventions. This essay critically evaluates the metaphors used by language experts to understand the unintended consequences for community members who are actively revitalising and reclaiming their languages. The essay also identifies key strategies used by community language activists to ignore existing metaphors, while creating new metaphors to potentiate new solutions to language death to promote emergent vitalities.     

When Do Natural Language Metaphors Influence Reasoning? A Follow-Up Study to Thibodeau and Boroditsky (2013)

In this article, we offer a critical view of Thibodeau and Boroditsky who report an effect of metaphorical framing on readers'' preference for political measures after exposure to a short text on the increase of crime in a fictitious town: when crime was metaphorically presented as a beast, readers became more enforcement-oriented than when crime was metaphorically framed as a virus. We argue that the design of the study has left room for alternative explanations. We report four experiments comprising a follow-up study, remedying several shortcomings in the original design while collecting more encompassing sets of data. Our experiments include three additions to the original studies: (1) a non-metaphorical control condition, which is contrasted to the two metaphorical framing conditions used by Thibodeau and Boroditsky, (2) text versions that do not have the other, potentially supporting metaphors of the original stimulus texts, (3) a pre-exposure measure of political preference (Experiments 1–2). We do not find a metaphorical framing effect but instead show that there is another process at play across the board which presumably has to do with simple exposure to textual information. Reading about crime increases people''s preference for enforcement irrespective of metaphorical frame or metaphorical support of the frame. These findings suggest the existence of boundary conditions under which metaphors can have differential effects on reasoning. Thus, our four experiments provide converging evidence raising questions about when metaphors do and do not influence reasoning.     

A Dataset of Metaphors from the Italian Literature: Exploring Psycholinguistic Variables and the Role of Context

Defining the specific role of the factors that affect metaphor processing is a fundamental step for fully understanding figurative language comprehension, either in discourse and conversation or in reading poems and novels. This study extends the currently available materials on everyday metaphorical expressions by providing the first dataset of metaphors extracted from literary texts and scored for the major psycholinguistic variables, considering also the effect of context. A set of 115 Italian literary metaphors presented in isolation (Experiment 1) and a subset of 65 literary metaphors embedded in their original texts (Experiment 2) were rated on several dimensions (word and phrase frequency, readability, cloze probability, familiarity, concreteness, difficulty and meaningfulness). Overall, literary metaphors scored around medium-low values on all dimensions in both experiments. Collected data were subjected to correlation analysis, which showed the presence of a strong cluster of variables—mainly familiarity, difficulty, and meaningfulness—when literary metaphor were presented in isolation. A weaker cluster was observed when literary metaphors were presented in the original contexts, with familiarity no longer correlating with meaningfulness. Context manipulation influenced familiarity, concreteness and difficulty ratings, which were lower in context than out of context, while meaningfulness increased. Throughout the different dimensions, the literary context seems to promote a global interpretative activity that enhances the open-endedness of the metaphor as a semantic structure constantly open to all possible interpretations intended by the author and driven by the text. This dataset will be useful for the design of future experimental studies both on literary metaphor and on the role of context in figurative meaning, combining ecological validity and aesthetic aspects of language.     

Phonetic Ability and Related Anatomy of the Newborn and Adult Human, Neanderthal Man, and the Chimpanzee

The sounds of human speech make human language a rapid medium of communication through a process of speech "encoding." The presence of sounds like the vowels [a], [i], and [u] makes this process possible. The supralaryngeal vocal tracts of newborn Homo sapiens and chimpanzee are similar and resemble the reconstructed vocal tract of the fossil La Chapelle-aux-Saints Neanderthal man. Vocal tract area functions that were directed toward making best possible approximations to the human vowels [a], [i], and [u], as well as certain consonantal configurations, were modeled by means of a computer program. The lack of these vowels in the phonetic repertories of these creatures, who lack a supralaryngeal pharyngeal region like that of adult Homo sapiens, may be concomitant with the absence of speech encoding and a consequently linguistic ability inferior to modern man.     

Dreaming and the Impossible Art of Translation

This essay identifies translation both as an historically core metaphor in Euro-American dream theory and as a contemporary ally for dream teaching and research. It also traces the mutuality of translators' reliance on Freud, Jung, and other dream theorists in their metaphorical expression of the art and craft of translation. The sustained interaction of oneiric and linguistic metaphor-making stems from the fact that virtually all of our knowledge about dreams has been mediated through language and that all dream reporting is itself an act of intersemiotic translation. In an attempt to stimulate further comparative inquiry, the overlapping concerns and often uncanny affinities between language/translation studies and dream/interpretation studies are presented.     

Animal Metaphors and Metaphorizing Animals: An Integrated Literary, Cognitive, and Evolutionary Analysis of Making and Partaking of Stories

Humans use metaphors to explore their relationship with nature. Our ability to make and understand metaphors appears to be an automatic cognitive process, one that likely evolved along with our ability to create and understand language. Because metaphors are processed automatically, without conscious appraisal, they can be used to rapidly communicate, or manipulate. Applying theories of evolutionary psychology and cognitive science to literary texts, we explored the role of animal metaphors in the making and partaking of stories in the context of a course in environmental studies. We investigated how humans are animals and yet use culture to shield themselves from this reality. We read and analyzed literature in which animal metaphors are central, such as Honoré de Balzac’s short story Passion in the Desert and Langdon Smith’s poem “Evolution.” Throughout the course, the overarching theme is that animal metaphors are powerful tools for framing our relationship with the environment and that they can be best understood in the context of humans as evolved animals.
