Social network structure has been argued to shape the structure of languages, as well as affect the spread of innovations and the formation of conventions in the community. Specifically, theoretical and computational models of language change predict that sparsely connected communities develop more systematic languages, while tightly knit communities can maintain high levels of linguistic complexity and variability. However, the role of social network structure in the cultural evolution of languages has never been tested experimentally. Here, we present results from (...) a behavioral group communication study, in which we examined the formation of new languages created in the lab by micro‐societies that varied in their network structure. We contrasted three types of social networks: fully connected, small‐world, and scale‐free. We examined the artificial languages created by these different networks with respect to their linguistic structure, communicative success, stability, and convergence. Results did not reveal any effect of network structure for any measure, with all languages becoming similarly more systematic, more accurate, more stable, and more shared over time. At the same time, small‐world networks showed the greatest variation in their convergence, stabilization, and emerging structure patterns, indicating that network structure can influence the community's susceptibility to random linguistic changes (i.e., drift).

People differ in the size of their social network, and thus in the properties of the linguistic input they receive. This article examines whether differences in social network size influence individuals’ linguistic skills in their native language, focusing on global comprehension of evaluative language. Study 1 exploits the natural variation in social network size and shows that individuals with larger social networks are better at understanding the valence of restaurant reviews. Study 2 manipulated social network size by randomly assigning participants (...) to learn novel evaluative words as used by two versus eight speakers. It replicated the finding from Study 1, showing that those exposed to a larger social network were better at comprehending the valence of product reviews containing the novel words that were written by novel speakers. Together, these studies show that the size of one's social network can influence success at language comprehension. They thus open the door to research on how individuals’ lifestyle and the nature of their social interactions can influence linguistic skills. (shrink)

Sociolinguistic research shows that listeners' expectations of speakers influence their interpretation of the speech, yet this is often ignored in cognitive models of language comprehension. Here, we focus on the case of interactions between native and non-native speakers. Previous literature shows that listeners process the language of non-native speakers in less detail, because they expect them to have lower linguistic competence. We show that processing the language of non-native speakers increases lexical competition and access in general, not only of the (...) non-native speaker's speech, and that this leads to poorer memory of one's own speech during the interaction. We further find that the degree to which people adjust their processing to non-native speakers is related to the degree to which they adjust their speech to them. We discuss implications for cognitive models of language processing and sociolinguistic research on attitudes. (shrink)

Successful communication is important for both society and people’s personal life. Here we show that people can improve their communication skills by interacting with multiple others, and that this improvement seems to come about by a greater tendency to take the addressee’s perspective when there are multiple partners. In Experiment 1, during a training phase, participants described figures to a new partner in each round or to the same partner in all rounds. Then all participants interacted with a new partner (...) and their recordings from that round were presented to naïve listeners. Participants who had interacted with multiple partners during training were better understood. This occurred despite the fact that the partners had not provided the participants with any input other than feedback on comprehension during the interaction. In Experiment 2, participants were asked to provide descriptions to a different future participant in each round or to the same future participant in all rounds. Next they performed a surprise memory test designed to tap memory for global details, in line with the addressee’s perspective. Those who had provided descriptions for multiple future participants performed better. These results indicate that people can improve their communication skills by interacting with multiple people, and that this advantage might be due to a greater tendency to take the addressee’s perspective in such cases. Our findings thus show how the social environment can influence our communication skills by shaping our own behavior during interaction in a manner that promotes the development of our communication skills.

Foreign-accented speech is generally harder to understand than native-accented speech. This difficulty is reduced for non-native listeners who share their first language with the non-native speaker. It is currently unclear, however, how non-native listeners deal with foreign-accented speech produced by speakers of a different language. We show that the process of language acquisition is associated with an increase in the relative difficulty of processing foreign-accented speech. Therefore, experiencing greater relative difficulty with foreign-accented speech compared with native speech is a marker (...) of language proficiency. These results contribute to our understanding of how phonological categories are acquired during second language learning. (shrink)

A classic example of the arbitrary relation between the way a word sounds and its meaning is that microorganism is a very long word that refers to a very small entity, whereas whale is a very short word that refers to something very big. This example, originally presented in Hockett's list of language's design features, has been often cited over the years, not only by those discussing the arbitrary nature of language, but also by researchers of sound symbolism. While the (...) two groups disagreed regarding the role of arbitrariness and sound symbolism in language, they both agreed there is a nonsound symbolic relation between word length and entity size in this case. This paper shows that the length of the words whale and microorganism in fact reflects a sound symbolic pattern. An analysis of >600 languages from >100 language families shows that languages use longer words to denote the concept small than they do to denote the concept big. The paper thus shows how explicit judgments might differ from implicit cognitive association and the problem of relying on these in sound symbolism research. (shrink)

Propagation of novel linguistic terms is an important aspect of language use and language change. Here, we test how social network size influences people's likelihood of adopting novel labels by examining hashtag use on Twitter. Specifically, we test whether following fewer Twitter users leads to more varied and malleable hashtag use on Twitter, because each followed user is ascribed greater weight and thus exerts greater influence on the following user. Focusing on Dutch users tweeting about the terrorist attack in Brussels (...) in 2016, we show that people who follow fewer other users use a larger number of unique hashtags to refer to the event, reflecting greater malleability and variability in use. These results have implications for theories of language learning, language use, and language change. (shrink)

Our sense of entitlement influences our interactions and attitudes in a range of specific relational contexts, one of them being aging parents’ relationships with their adult children. This study aimed to examine the factor structure of the Sense of Relational Entitlement—aging parents toward their offspring, an 11-item questionnaire that assesses aging people’s sense of relational entitlement toward their children, and examine the associations of its subscales with related personality and mental health constructs. One thousand and six participants, aged 65–99, with (...) at least one child, completed the SRE-ao, Brief Symptom Inventory, Loneliness Scale, and General Belongingness scale. The SRE-ao demonstrated good construct structure using confirmatory factor analysis. Both SRE-ao subscales were significantly and positively associated with anxiety, depression, somatization and sense of loneliness and negatively with sense of belonging. When all variables were entered into a regression model, age, anxiety, and low sense of belonging, but not sense of loneliness, positively predicted both restricted and inflated sense of entitlement. Somatization negatively predicted inflated sense of entitlement. The SRE-ao is a reliable and valid scale that can be used in clinical practice and research to enhance our understanding of parent–child relationships throughout the lifespan. (shrink)

Maxmin Expected Utility was first axiomatized by Gilboa and Schmeidler in an Anscombe–Aumann setup Anscombe and Aumann which includes exogenous probabilities. The model was later axiomatized in a purely subjective setup, where no exogenous probabilities are assumed. The purpose of this note is to show that in all these axiomatizations, the only assumptions that are needed are the basic ones that are used to extract a cardinal utility function, together with the two typical Maxmin assumptions, Uncertainty Aversion and Certainty Independence, (...) applied only to 0.5:0.5 mixtures. For the purely subjective characterizations, this means that assumptions involving an unbounded number of variables can be replaced with assumptions that involve only a finite number thereof.

What is the significance of GDP per capita to a society? What does it represent conceptually? These questions have been addressed in past decades, engendering extensive explorations of the limitations of the indicator, yet answers have proved problematic or partial. The paper presents the main conclusions so far drawn and builds upon them to present a new reading of the significance of GDP per capita. At the heart of this reading is the view that, while GDP per capita is not (...) indicative of the welfare of individuals, it is indicative of an irreducible ‘group well-being.’ This view, however, requires one to relinquish the belief that only individuals can be ‘well.’ It turns out that the allegedly orthodox view, which sees GDP as a human-centered indicator, requires an unorthodox philosophical standpoint, one that accepts an irreducible group well-being. The paper presents this alternative interpretation and addresses its upsides and limitations. (shrink)

Edgeworth's original mathematical formalization of utilitarianism as presented in his works of 1877–81 illustrates an intriguing phase in the mutually intertwined history of economics and utilitarianism. In this article I analyse Edgeworth's motivations and point to its interesting implications. In particular, it is pointed out that the starting point of Edgeworth's project had little to do with the field of economics, but formed part of an attempt to present utilitarianism in the most scientific way possible; an attempt made in the (...) context of intensive dispute between the three opposing camps in the field of ethics at the time. Nevertheless, the project concluded with the monograph Mathematical Psychics (1881) that embodied an original relationship between economics and utilitarianism. (shrink)

Character strengths are widely studied positive traits considered to be “values in action,” reflecting morally valued virtues. They are hypothesized to serve as pathways to the manifestation of values in life for the benefit of individuals and societies. However, there is surprisingly limited theoretical writing and empirical research on the expected links of character strengths with specific values [e.g., as defined by Schwartz ] or on character strengths as the pathway for behavioral and social manifestations of these values. In this (...) paper, we delineate theoretical links between the two theories and outline their implications. We then provide an initial empirical examination of a specific character strength – gratitude, as a pathway from Schwartz’s self-transcendence values to prosocial behavior and peer acceptance, in two samples of adolescents. The findings indicated that most pathways were significant, providing initial support for the theoretical model. However, in one of the samples, the indirect path from self-transcendence values to prosocial behavior was only marginally significant. Taken together, the findings point to the need for further research on the role of character strengths in creating a pathway from values to various social outcomes. (shrink)

Organizational citizenship behavior (OCB) is considered vital for organizations’ performance, and there is notable interest in factors that foster it. However, recent research has questioned the absolute positivity of OCB and pointed to its understudied possible adverse effects (e.g., on employees’ well-being). The present research aims to shed light on these issues by exploring the daily dynamics of employees’ social and emotional work lives’ interplay with their OCB. Specifically, the research focuses on teachers, whose job enables notable OCB and whose (...) performance is profoundly affected by it. Based on the literature linking work relationships and emotional experiences with OCB, we examined the interplay between teachers’ OCB and their daily perceived supervisor and colleague support, and daily positive and negative emotional experiences. Sixty teachers completed self-report questionnaires of the research variables every day for twelve workdays. Results indicated significant associations of daily supervisor support and negative emotions with increased OCB on the following day, links of daily positive emotions with decreased OCB on the following day, and associations of daily OCB with increased negative emotions on the following day. These findings point to daily processes that may underly longer-term effects of OCB (such as burnout), including a potential downward spiral of negative emotions that seem to result from OCB and reinforce it.

Progressions of iterated reflection principles can be used as a tool for the ordinal analysis of formal systems. We discuss various notions of proof-theoretic ordinals and compare the information obtained by means of the reflection principles with the results obtained by the more usual proof-theoretic techniques. In some cases we obtain sharper results, e.g., we define proof-theoretic ordinals relevant to logical complexity Π1 0 and, similarly, for any class Π n 0 . We provide a more general version of the (...) fine structure relationships for iterated reflection principles (due to U. Schmerl [25]). This allows us, in a uniform manner, to analyze main fragments of arithmetic axiomatized by restricted forms of induction, including IΣ n , IΣ n − , IΠ n − and their combinations. We also obtain new conservation results relating the hierarchies of uniform and local reflection principles. In particular, we show that (for a sufficiently broad class of theories T) the uniform Σ1-reflection principle for T is Σ2-conservative over the corresponding local reflection principle. This bears some corollaries on the hierarchies of restricted induction schemata in arithmetic and provides a key tool for our generalization of Schmerl's theorem. (shrink)

We suggest an algebraic approach to proof-theoretic analysis based on the notion of graded provability algebra, that is, Lindenbaum boolean algebra of a theory enriched by additional operators which allow for the structure to capture proof-theoretic information. We use this method to analyze Peano arithmetic and show how an ordinal notation system up to 0 can be recovered from the corresponding algebra in a canonical way. This method also establishes links between proof-theoretic ordinal analysis and the work which has been (...) done in the last two decades on provability logic and reflection principles. Because of its abstract algebraic nature, we hope that it will also be of interest for non-prooftheorists. (shrink)

We deal with the fragment of modal logic consisting of implications of formulas built up from the variables and the constant ‘true’ by conjunction and diamonds only. The weaker language allows one to interpret the diamonds as the uniform reflection schemata in arithmetic, possibly of unrestricted logical complexity. We formulate an arithmetically complete calculus with modalities labeled by natural numbers and ω, where ω corresponds to the full uniform reflection schema, whereas n<ω corresponds to its restriction to arithmetical Πn+1-formulas. This (...) calculus is shown to be complete w.r.t. a suitable class of finite Kripke models and to be decidable in polynomial time. (shrink)

This paper has two goals. First, we develop frameworks for logical systems which are able to reflect not only non-monotonic patterns of reasoning, but also paraconsistent reasoning. Our second goal is to have a better understanding of the conditions that a useful relation for nonmonotonic reasoning should satisfy. For this we consider a sequence of generalizations of the pioneering works of Gabbay, Kraus, Lehmann, Magidor and Makinson. These generalizations allow the use of monotonic nonclassical logics as the underlying logic upon (...) which nonmonotonic reasoning may be based. Our sequence of frameworks culminates in what we call plausible, nonmonotonic, multiple-conclusion consequences relations . Our study yields intuitive justifications for conditions that have been proposed in previous frameworks and also clarifies the connections among some of these systems. In addition, we present a general method for constructing plausible nonmonotonic relations. This method is based on a multiple-valued semantics, and on Shoham's idea of preferential models. (shrink)

Prominent thinkers such as Jurgen Habermas and Michael Sandel are warning that biomedical enhancements will undermine fundamental political values. Yet whether biomedical enhancements will undermine such values depends on how biomedical enhancements will function, how they will be administered and to whom. Since only few enhancements are obtainable, it is difficult to tell whether these predictions are sound. Nevertheless, such warnings are extremely valuable. As a society we must, at the very least, be aware of developments that could have harmful (...) consequences. Indeed, if important values were to be jeopardized, we should take appropriate measures to protect them. This paper focuses on four central values: solidarity, personal responsibility, equality and autonomy. It delineates the conditions under which biomedical enhancements would undermine these values. It also details the circumstances under which these values would be unaffected by enhancements as well as those under which they would be promoted. Specifying these conditions is valuable; it would enable society to prepare appropriate ethical guidelines and policy responses in advance. (shrink)

For “natural enough” systems of ordinal notation we show that α times iterated local reflection schema over a sufficiently strong arithmetic T proves the same Π 1 0 -sentences as ω α times iterated consistency. A corollary is that the two hierarchies catch up modulo relative interpretability exactly at ε-numbers. We also derive the following more general “mixed” formulas estimating the consistency strength of iterated local reflection: for all ordinals α ⩾ 1 and all β, β ≡ Π 1 0 (...) T ω α · , α ≡ Π 1 0 T β + ω α . Here T α stands for α times iterated local reflection over T , T β stands for β times iterated consistency, and ≡ Π 1 0 denotes mutual Π 1 0 -conservativity. In an appendix to this paper we develop our notion of “natural enough” system of ordinal notation and show that such systems do exist for every recursive ordinal. (shrink)

The notion of bilattice was introduced by Ginsberg, and further examined by Fitting, as a general framework for many applications. In the present paper we develop proof systems, which correspond to bilattices in an essential way. For this goal we introduce the notion of logical bilattices. We also show how they can be used for efficient inferences from possibly inconsistent data. For this we incorporate certain ideas of Kifer and Lozinskii, which happen to suit well the context of our work. (...) The outcome are paraconsistent logics with a lot of desirable properties.1.

Analyzes principal forces that determined the direction of Camus' thought on ethics and political values.

The main focus of the book is the presentation of the 'inertial' view of population growth. This view provides a rather simple model for complex population dynamics, and is achieved at the level of the single species without invoking species interactions. An important part of this account is the maternal effect. Investment of mothers in the quality of their daughters makes the rate of reproduction of the current generation depend not only on the current environment, but also on the environment (...) experienced by the previous generation.

A well-known result states that, over basic Kalmar elementary arithmetic EA, the induction schema for ∑n formulas is equivalent to the uniform reflection principle for ∑n + 1 formulas . We show that fragments of arithmetic axiomatized by various forms of induction rules admit a precise axiomatization in terms of reflection principles as well. Thus, the closure of EA under the induction rule for ∑n formulas is equivalent to ω times iterated ∑n reflection principle. Moreover, for k < ω, k (...) times iterated ∑n reflection principle over EA precisely corresponds to the extension of EA by k nested applications of ∑n induction rule.The above relationship holds in greater generality than just stated. In fact, we give general formulas characterizing in terms of iterated reflection principles the extension of any given theory by k nested applications of ∑n or Πn induction rules. In particular, the closure of a theory T under just one application of ∑1 induction rule is equivalent to T together with ∑1 reflection principle for each finite Π2 axiomatized subtheory of T.These results have closely parallel ones in the theory of subrecursive function classes. The rules under study correspond, in a canonical way, to natural closure operators on the classes of provably recursive functions. Thus, ∑1 induction rule precisely corresponds to the primitive recursive closure operator, and ∑1 collection rule, introduced below, corresponds to the elementary closure operator. (shrink)

Provability logic GLP is well-known to be incomplete w.r.t. Kripke semantics. A natural topological semantics of GLP interprets modalities as derivative operators of a polytopological space. Such spaces are called GLP-spaces whenever they satisfy all the axioms of GLP. We develop some constructions to build nontrivial GLP-spaces and show that GLP is complete w.r.t. the class of all GLP-spaces.

Constructions of Intersubjectivity shows that the meaning of grammatical constructions often has more to do with the human cognitive capacity for taking other peoples' points of view than with describing the world. Treating pragmatics, semantics, and syntax in parallel and integrating insights from linguistics, psychology, and animal communication, Arie Verhagen develops a new understanding of linguistic communication. In doing so he shows the continuity between language and animal communication and reveals the nature of human linguistic specialization. Professor Verhagen uses Dutch (...) and English data from a wide variety of sources and considers the contributions of grammar to the coherence of discourse. He argues that important problems in semantics and syntax may be resolved if language is understood as an instrument for exerting influence and coordinating different perspectives. The grammatical phenomena he discusses include negative expressions, the let alone construction, complementation constructions, and discourse connectives.This powerfully argued and original explanation of the nature and operation of communication will interest a wide range of scholars and advanced students in linguistics, cognitive science, and human evolution.
