Academic writing is notoriously difficult to read. Can political science do better? To assess the state of prose in political science, we examined a recent issue of the American Political Science Review. We evaluated the articles according to the basic principles of style endorsed by writing experts. We find that the writing suffers most from heavy...

Significance Humans are an unusually cooperative species, and our cooperation is of 2 kinds: altruistic, when actors benefit others at a cost to themselves, and mutualistic, when actors benefit themselves and others simultaneously. One major form of mutualism is coordination, in which actors align their choices for mutual benefit. Formal examples i...

Why do people esteem anonymous charitable giving? We connect normative theories of charitability (captured in Maimonides’ Ladder of Charity) with evolutionary theories of partner choice to test predictions on how attributions of charitability are affected by states of knowledge: whether the identity of the donor or of the beneficiary is revealed to...

What is the relationship between the language people use to describe an event and their moral judgments? We test the hypothesis that moral judgment and causative verbs rely on the same underlying mental model of people’s actions. Experiment 1a finds that participants choose different verbs to describe the major variants of a moral dilemma, the trol...

The more potential helpers there are, the less likely any individual is to help. A traditional explanation for this bystander effect is that responsibility diffuses across the multiple bystanders, diluting the responsibility of each. We investigate an alternative, which combines the volunteer's dilemma (each bystander is best off if another respond...

Political bias has indeed been a distorter of psychology, not just in particular research areas but in an aversion to the explanatory depth available from politically fraught fields like evolution. I add two friendly amendments to the target article: (1) The leftist moral narrative may be based on zero-sum competition among identity groups rather t...

Significance People have long debated about the global influence of languages. The speculations that fuel this debate, however, rely on measures of language importance—such as income and population—that lack external validation as measures of a language’s global influence. Here we introduce a metric of a language’s global influence based on its pos...

Significance We identify several common genetic variants associated with cognitive performance using a two-stage approach: we conduct a genome-wide association study of educational attainment to generate a set of candidates, and then we estimate the association of these variants with cognitive performance. In older Americans, we find that these var...

Research on human cooperation has concentrated on the puzzle of altruism, in which 1 actor incurs a cost to benefit another, and the psychology of reciprocity, which evolved to solve this problem. We examine the complementary puzzle of mutualism, in which actors can benefit each other simultaneously, and the psychology of coordination, which ensure...

Specific language impairment (SLI), a genetic developmental disorder, offers insights into the neurobiological and computational organization of language. A subtype, Grammatical-SLI (G-SLI), involves greater impairments in ‘extended’ grammatical representations, which are nonlocal, hierarchical, abstract, and composed, than in ‘basic’ ones, which a...

What function do facial expressions have? We tested the hypothesis that some expressions serve as honest signals of subjective commitments-in particular, that angry faces increase the effectiveness of threats. In an ultimatum game, proposers decided how much money to offer a responder while seeing a film clip depicting an angry or a neutral facial...

Presents an obituary for George A. Miller (1920-2012). Miller ranks among the most important psychologists of the 20th century. In addition to writing one of the best known papers in the history of psychology ("The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information," published in Psychological Review in...

The debate on the waning of war has recently moved into higher gear. This forum contributes to that debate. Steven Pinker observes that a decline in war does not require a romantic theory of human nature. In fact, it is compatible with a hardheaded view of human violent inclinations, firmly rooted in evolutionary biology. Homo sapiens evolved with...

Objectives: We explain why traits of interest to behavioral scientists may have a genetic architecture featuring hundreds or thousands of loci with tiny individual effects rather than a few with large effects and why such an architecture makes it difficult to find robust associations between traits and genes. Methods: We conducted a genome-wide...

I present the hypothesis that human language is an adaptations that evolved by natural selection for communication in a knowledge-using, socially interdependent lifestyle, the “cognitive niche.” This lifestyle is a specialization for overcoming the evolutionary fixed defences of plants and animals (poisons, coverings, stealth, speed, and so on) by...

On top of all the benefits that modernity has brought us in health, experience, and knowledge, we can add its role in the reduction of violence.

Many humanities scholars have expressed a malaise about the current state of their fields, reflecting a lack of optimism about the possibility of a progressive agenda for the discovery and accumulation of knowledge. This chapter argues that consilience, with the social and biological sciences, offers the exciting prospect that both sets of fields c...

We are getting smarter, and as a result the world is becoming a more peaceful place, says Steven Pinker.

Self-deception is a powerful but overapplied theory. It is adaptive only when a deception-detecting audience is in the loop, not when an inaccurate representation is invoked as an internal motivator. First, an inaccurate representation cannot be equated with self-deception, which entails two representations, one inaccurate and the other accurate. S...

We constructed a corpus of digitized texts containing about 4% of all books ever printed. Analysis of this corpus enables us to investigate cultural trends quantitatively. We survey the vast terrain of ‘culturomics,’ focusing on linguistic and cultural phenomena that were reflected in the English language between 1800 and 2000. We show how this app...

Steven Pinker's The Better Angels of Our Nature: Why Violence Has Declined is a brilliant analysis of the decline in human violence over the past several centuries and of the social and psychological processes associated with this decline. His sweeping work encompasses the intricacies of the medieval practice of breaking miscreants on the wheel, to...

Embora Darwin tenha insistido que a inteligência humana pudesse ser inteiramente explicada pela teoria da evolução, o co-descobridor da seleção natural, Alfred Russel Wallace, afirmou que a inteligência abstrata era de nenhuma serventia para os ancestrais humanos e só poderia ser explicada pelo design inteligente. 2 O aparente paradoxo de Wallace p...

Whether a word has an irregular inflection does not depend on its sound alone: compare lie-lay (recline) and lie-lied (prevaricate). Theories of morphology, particularly connectionist and symbolic models, disagree on which nonphonological factors are responsible. We test four possibilities: (1) Lexical effects, in which two lemmas differ in whether...

Speakers often do not state requests directly but employ innuendos such as Would you like to see my etchings? Though such indirectness seems puzzlingly inefficient, it can be explained by a theory of the strategic speaker, who seeks plausible deniability when he or she is uncertain of whether the hearer is cooperative or antagonistic. A paradigm ca...

Although Darwin insisted that human intelligence could be fully explained by the theory of evolution, the codiscoverer of natural selection, Alfred Russel Wallace, claimed that abstract intelligence was of no use to ancestral humans and could only be explained by intelligent design. Wallace's apparent paradox can be dissolved with two hypotheses ab...

While endorsing Evans & Levinson's (E&L's) call for rigorous documentation of variation, we defend the idea of Universal Grammar as a toolkit of language acquisition mechanisms. The authors exaggerate diversity by ignoring the space of conceivable but nonexistent languages, trivializing major design universals, conflating quantitative with qualitat...

Seeing the Brain's One, Two, Three Taking advantage of the rare opportunity to record neuronal activity in the human brain using intracranial electrodes, Sahin et al. (p. 445 ; see the Perspective by Hagoort and Levelt ) document the spatial and temporal pattern of neuronal populations within Broca's area as patients thought of a single word, chang...

Hauser, Chomsky, and Fitch (HCF) proposed that recursion is the only thing that distinguishes language (a) from other human capacities, and (b) from the capacities of animals. These factors are independent. The narrow faculty of language might include more than recursion, falsifying (a). Or it might consist only of recursion, although parts of the...

ONE OF THE PERKS of being a psychologist is access to tools that allow you to carry out the injunction to know thyself. I have been tested for vocational interest (closest match: psychologist), intelligence (above average), personality (open, conscientious, agreeable, average in extraversion, not too neurotic) and political orientation (neither lef...

Why do compounds containing regular plurals, such as rats-infested, sound so much worse than corresponding compounds containing irregular plurals, such as mice-infested? Berent and Pinker (2007) reported five experiments showing that this theoretically important effect hinges on the morphological structure of the plurals, not their phonological pro...

This chapter confronts several fears that determinism engenders, such as the fear that deep down we are not in control of our own choices, and the fear that determinism makes it impossible to hold anyone accountable for their actions. Although the fear of biological determinism seems to many people more frightening, environmental determinism must c...

When people speak, they often insinuate their intent indirectly rather than stating it as a bald proposition. Examples include sexual come-ons, veiled threats, polite requests, and concealed bribes. We propose a three-part theory of indirect speech, based on the idea that human communication involves a mixture of cooperation and conflict. First, in...

Which of the following people would you say is the most admirable: Mother Teresa, Bill Gates or Norman Borlaug? And which do you think is the least admirable? For most people, it's an easy question. Mother Teresa, famous for ministering to the poor in Calcutta, has been beatified by the Vatican, awarded the Nobel Peace Prize and ranked in an Americ...

English speakers disfavor compounds containing regular plurals compared to irregular ones. Haskell, MacDonald and Seidenberg (2003) attribute this phenomenon to the rarity of compounds containing words with the phonological properties of regular plurals. Five experiments test this proposal. Experiment 1 demonstrated that novel regular plurals (e.g....

This paper proposes a new analysis of indirect speech in the framework of game theory, social psychology, and evolutionary psychology. It builds on the theory of Grice, which tries to ground indirect speech in pure rationality (the demands of efficient communication between two cooperating agents) and on the Politeness Theory of Brown and Levinson,...

The role of Broca's area in grammatical computation is unclear, because syntactic processing is often confounded with working memory, articulation, or semantic selection. Morphological processing potentially circumvents these problems. Using event-related functional magnetic resonance imaging (fMRI), we had 18 subjects silently inflect words or rea...

Portugues O debate genética-cultura tem sido uma preocupação para a Psicologia e para as Ciências Sociais há séculos. Muitos escritores têm expressado uma esperança que se chegue a um meio termo que faça o debate desaparecer. Neste meio termo, todo comportamento vem de uma interação intrincada entre a hereditariedade e o meio ambiente, e seria um e...

In a continuation of the conversation with Fitch, Chomsky, and Hauser on the evolution of language, we examine their defense of the claim that the uniquely human, language-specific part of the language faculty (the “narrow language faculty”) consists only of recursion, and that this part cannot be considered an adaptation to communication. We argue...

The distinction between singular and plural enters into linguistic phenomena such as morphology, lexical semantics, and agreement and also must interface with perceptual and conceptual systems that assess numerosity in the world. Three experiments examine the computation of semantic number for singulars and plurals from the morphological properties...

We examine the question of which aspects of language are uniquely human and uniquely linguistic in light of recent suggestions by Hauser, Chomsky, and Fitch that the only such aspect is syntactic recursion, the rest of language being either specific to humans but not to language (e.g. words and concepts) or not specific to humans (e.g. speech perce...

In my book How the Mind Works, I defended the theory that the human mind is a naturally selected system of organs of computation. Jerry Fodor claims that ‘the mind doesn’t work that way’(in a book with that title) because (1) Turing Machines cannot duplicate humans’ ability to perform abduction (inference to the best explanation); (2) though a mass...

MacWhinney is to be commended for reopening questions about the logical problem of language acquisition in the light of new data and models. Unfortunately his discussion is marred by technical errors, false dichotomies, and inadequate attention to detail. The ‘logical problem of language acquisition ’ (Baker & McCarthy, 1981 ; Pinker, 1979, 1989) i...

Psychology Version of Record

Does knowledge of language consist of mentally-represented rules? Rumelhart and McClelland have described a connectionist (parallel distributed processing) model of the acquisition of the past tense in English which successfully maps many stems onto their past tense forms, both regular (walk/walked) and irregular (go/went), and which mimics some of...

study, taking truly independent ratings to see which verbs participants considered to be denominal or deverbal (i.e. exocentric or not). The results of this new experiment were clear. The semantic similarity (or otherwise) of verbs-incontext to ordinary irregular usage predicted the acceptability of past-tense forms. Whether or not verbs were perce...

In The Blank Slate, Steven Pinker, one of the world's leading experts on language and the mind, explores the idea of human nature and its moral, emotional, and political colorings. With characteristic wit, lucidity, and insight, Pinker argues that the dogma that the mind has no innate traits-a doctrine held by many intellectuals during the past cen...

What is the interaction between storage and computation in language processing? What is the psychological status of grammatical rules? What are the relative strengths of connectionist and symbolic models of cognition? How are the components of language implemented in the brain? The English past tense has served as an arena for debates on these issu...

Most evidence for the role of regular inflection as a default operation comes from languages that confound the morphological properties of regular and irregular forms with their phonological characteristics. For instance, regular plurals tend to faithfully preserve the base's phonology (e.g., rat-rats), whereas irregular nouns tend to alter it (e.g...

Does our ability to talk lie in our genes? The suspicion is bolstered by the discovery of a gene that might affect how the brain circuitry needed for speech and language develops.

There are no fossils to show how language evolved. But evolutionary game theory is revealing how some of the defining features of human language could have been shaped by natural selection.

According to the 'word/rule' account, regular inflection is computed by a default, symbolic process, whereas irregular inflection is achieved by associative memory. Conversely, pattern-associator accounts attribute both regular and irregular inflection to an associative process. The acquisition of the default is ascribed to the asymmetry in the dis...
