A popular goal in psychological science is to understand human cognition and behavior in the ‘real world’. In contrast, researchers have typically conducted their research in experimental research settings, a.k.a. the ‘psychologist’s laboratory’. Critics have often questioned whether psychology’s laboratory experiments permit generalizable results. This is known as the ‘real-world or the lab’-dilemma. To bridge the gap between lab and life, the concept of ecological validity has been widely used to evaluate whether laboratory experiments resemble and generalize to the ‘real (...) world’. However, researchers seldom define what they mean with this concept, nor are there any guidelines or criteria available for evaluating a study’s ecological validity. In our view, the popular concept of ecological validity is ill-formed, lacks specificity, and falls short of adequately addressing the fundamental problem of generalizability. In order to move beyond this ‘real-world or the lab’-dilemma, we believe that researchers should be more specific about the contexts of behaviors they are interested in, instead of aiming to understand human cognition and behavior in the ‘real world’. We argue that this is a more constructive way of uncovering the context-specific and context-generic principles of human cognition and behavior. (shrink)

We disagree with Almaatouq et al. that no realistic alternative exists to the “one-at-a-time” paradigm. Seventy years ago, Egon Brunswik introduced representative design, which offers a clear path to commensurability and generality. Almaatouq et al.'s integrative design cannot guarantee the external validity and generalizability of results which is sorely needed, while representative design tackles the problem head on.

We develop a vector space semantics for verb phrase ellipsis with anaphora using type-driven compositional distributional semantics based on the Lambek calculus with limited contraction of Jäger. Distributional semantics has a lot to say about the statistical collocation based meanings of content words, but provides little guidance on how to treat function words. Formal semantics on the other hand, has powerful mechanisms for dealing with relative pronouns, coordinators, and the like. Type-driven compositional distributional semantics brings these two models together. We (...) review previous compositional distributional models of relative pronouns, coordination and a restricted account of ellipsis in the DisCoCat framework of Coecke et al. :1079–1100, 2013). We show how DisCoCat cannot deal with general forms of ellipsis, which rely on copying of information, and develop a novel way of connecting typelogical grammar to distributional semantics by assigning vector interpretable lambda terms to derivations of LCC in the style of Muskens and Sadrzadeh Logical aspects of computational linguistics, Springer, Berlin, 2016). What follows is an account of ellipsis in which word meanings can be copied: the meaning of a sentence is now a program with non-linear access to individual word embeddings. We present the theoretical setting, work out examples, and demonstrate our results with a state of the art distributional model on an extended verb disambiguation dataset. (shrink)

In ‘Exploitation, Labor, and Basic Income’ Michael Howard undertakes to defend an Unconditional Basic Income (UBI) as non-exploitative, and on a revised conception of what Marx called ‘exploitation’. Without taking issue with the revision itself, I point out that Howard, like many others, fails to defend UBI as non-exploitative. All his arguments fail to establish that the so-called ‘Surfer off Malibu’, a figure who is full-time dedicated to leisure, is not an exploiter in receiving UBI. The strategies to include him (...) as a rightful recipient of a labor-free income rely on the (sometimes far-fetched) attribution of certain contingent features to him that would entitle him to compensation or reward, but that he might also not have. I argue that the best strategy for UBI-advocates is to admit that ‘slackers’ should be merely tolerated as non-deserving recipients, because the UBI-policy will otherwise have good effects. Finally, I raise some questions about these good effects, as they are conceived by UBI-advocates such as Howard. (shrink)

Numerous studies have convincingly shown that prospect theory can better describe risky choice behavior than the classical expected utility model because it makes the plausible assumption that risk aversion is driven not only by the degree of sensitivity toward outcomes, but also by the degree of sensitivity toward probabilities. This article presents the results of an experiment aimed at testing whether agents become more sensitive toward probabilities over time when they repeatedly face similar decisions, receive feedback on the consequences of (...) their decisions, and are given ample incentives to reflect on their decisions, as predicted by Plott’s Discovered Preference Hypothesis (DPH). The results of a laboratory experiment with N = 62 participants support this hypothesis. The elicited subjective probability weighting function converges significantly toward linearity when respondents are asked to make repeated choices and are given direct feedback after each choice. Such convergence to linearity is absent in an experimental treatment where respondents are asked to make repeated choices but do not experience the resolution of risk directly after each choice, as predicted by the DPH.

In this paper we describe a test for Nijhout's hypothesis that the eyespot patterns on butterfly wings are the result of a threshold reaction of the epidermal cells to a concentration gradient of a diffusing degradable morphogen produced by focal cells at the centre of the future eyespot. The wings of the nymphalid butterfly, Bicyclus anynana, have a series of eyespots, each composed of a white pupil, a black disc and a gold outer ring. In earlier extirpation and transplantation experiments (...) it has been established that these eyespots are indeed organised around groups of signalling cells active during the first hours of pupal development. If these cells were to supply the positional information for eyespot formation in accordance with Nijhout's diffusion-degradation gradient model, then, when two foci are close together, the signals should sum, and this effect should be apparent in the detailed shape of the resulting pigment pattern. We give an equation for the form of the contours that would be obtained in this manner. We use this to test the morphogen gradient hypothesis on measurements of the outlines of fused eyespots obtained either by grafting focal cells close together, or by using a mutation that produces adjacent fused eyespots. The contours of the fused patterns were found to satisfy our equation, thus corroborating Nijhout's hypothesis to the extent possible with this particular type of experiment. (shrink)

Of late, historians have been realising that South Asia and Europe have more in common than a particular strand in the historiography on "the rise of the West" would have us believe. In both world regions a plurality of languages, religions, and types of belonging by birth was in premodern times matched by a plurality of legal systems and practices. This volume describes case-by-case the points where law and social diversity intersected.

Presentation times of study words presented in the Deese/Roediger and McDermott (DRM) paradigm varied from 20 to 2000 ms per word in an attempt to replicate the false memory effect following extremely short presentations reported by . Both in a within-subjects design (Experiment 1) and in a between-subjects design (Experiment 2) subjects showed memory for studied words as well as a false memory effect for related critical lures in the 2000-ms condition. However, in the conditions with shorter presentation times (20 (...) ms in Experiment 1; 20 and 40 ms in Experiment 2) no memory for studied words, nor a false memory effect was found. We argue that there is at present no strong evidence supporting the claim for a nonconscious basis of the false memory effect. (shrink)

This book explores how traditional theories of economic justice, both from the libertarian right and the egalitarian left, have failed to appreciate the objection against exploitative behavior that would be possible through the exercise of property rights. This failure also underlies the recent plea for a so-called unconditional basic income.

Within the literature on emotion and behavioral action, studies on approach-avoidance take up a prominent place. Several experimental paradigms feature successful conceptual replications but many original studies have not yet been replicated directly. We present such a direct replication attempt of two seminal experiments originally conducted by Chen and Bargh (1999). In their first experiment, participants affectively evaluated attitude objects by pulling or pushing a lever. Participants who had to pull the lever with positively valenced attitude objects and push the (...) lever with negatively valenced attitude objects (i.e., congruent instruction) did so faster than participants who had to follow the reverse (i.e., incongruent) instruction. In Chen and Bargh's second experiment, the explicit evaluative instructions were absent and participants merely responded to the attitude objects by either always pushing or always pulling the lever. Similar results were obtained as in Experiment 1. Based on these findings, Chen and Bargh concluded that (1) attitude objects are evaluated automatically; and (2) attitude objects automatically trigger a behavioral tendency to approach or avoid. We attempted to replicate both experiments and failed to find the effects reported by Chen and Bargh as indicated by our pre-registered Bayesian data analyses; nevertheless, the evidence in favor of the null hypotheses was only anecdotal, and definitive conclusions await further study.

This article presents the results of an experiment that completely measures the utility function and probability weighting function for different positive and negative monetary outcomes, using a representative sample of N = 1,935 from the general public. The results confirm earlier findings in the lab, suggesting that utility is less pronounced than what is found in classical measurements where expected utility is assumed. Utility for losses is found to be convex, consistent with diminishing sensitivity, and the obtained loss-aversion coefficient of (...) 1.6 is moderate but in agreement with contemporary evidence. The estimated probability weighting functions have an inverse-S shape and they imply pessimism in both domains. These results show that probability weighting is also an important phenomenon in the general population. Women and lower educated individuals are found to be more risk averse, in agreement with common findings. In contrast to previous studies that ascribed gender differences in risk attitudes solely to differences in the degree utility curvature, however, our results show that this finding is primarily driven by loss aversion and, for women, also by a more pessimistic psychological response toward the probability of obtaining the best possible outcome.

The concept of interpassivity, coined by Žižek and Robert Pfaller in the nineties, delineates an original and fruitful field of research that deserves to be developed further. First, interpassivity should be understood in a historical way, as originating with modernity. Second, interpassivity should thus be identified with modernity, in that it expresses modernity’s preoccuption with activity. This explains why interpassivity should be understood as the delegation or ‘outsourcing’ of passivity, in order to become even more active, as Pfaller and Žižek (...) claim. But thirdly, the occupations of late or post-modernity invite us to understand interpassivity still differently: as the outsourcing of activity, not passivity. (shrink)

Punishment and forgiveness are two very different responses to a moral transgression that both have been argued to restore perceptions of moral order within an organization. Unfortunately, it is currently unclear what motivates organizational actors to punish or forgive a norm transgressor. We build on social cognitive theory to argue that punishment and forgiveness of a transgressor are both rooted in self-regulatory processes. Specifically, we argue that organizational actors are more likely to respond to intentional transgressions with punishment, and to (...) unintentional transgressions with forgiveness. However, these effects of transgressor intentionality should be found in particular among actors for whom moral identity is central. We find support for these predictions in a laboratory experiment and a field study among organizational leaders. By simultaneously studying punishment and forgiveness in organizational settings, we provide crucial insight in their shared motivational bases, as well as into important differences between the two.

This interpretation of the Odyssey challenges conventional readings in a way that recaptures the strangeness in a text that has been colonized by interpretative strategies, interpretations that impose certain cultural and gendered stereotypes. My reading inverts and subverts some of these stereotypes, without claiming to reveal, or aiming to establish, true identities. Rather, my point is that identities are unstable and unpredictable; the main characters in the Odyssey can be understood best by analysing their characteristic style of dealing with these (...) uncertainties. In this light, Odysseus appears as much less stable and much less ‘in control’ than in standard readings. His presumed, and famed, autonomy is shown to be largely a product of self‐deception, deriving from an inability to confront himself. The women in the Odyssey, on the other hand, are stronger characters, both less helpless, and more helpful, than standard readings allow for. Calypso and Circe play a positive role in liberating and educating Odysseus. Penelope, for her part, turns out to be involved in a much more subtle and elusive form of self‐fabrication than Odysseus. Rather than applying stereotypes of cunning' or ‘faithful’, we should understand both Odysseus' and Penelope's actions as the product of their own idiosyncratic way of dealing with contingency, within the bounds set by cultural and natural circumstance.

Identity politics, like Krisis, has its origins in the early 1980s. This coincides with Michel Foucault’s rejection of demands or claims of identity as ‘to be left to the police’. In a strange but perhaps inevitable twist of fate, identity politics has later one become affiliated precisely with policing, leading to political correctness in which identity claims are both mandatory and subject to politically motivated censure. While initially in the service of emancipation, identity has thus become weaponized, which reflects an (...) important shift in political and cultural sensitivities between the 1980s and the 2010s.

Real-libertarianism, as it is expressed in Philippe Van Parijs' recent monograph Real Freedom for All is characteristically committed to both self-ownership and 'solidarity with the infirm or handicapped. In this article it is argued that the conception of freedom that is used to endorse self-ownership is inconsistent with the conception of freedom or opportunity that is used to justify transfer payments to those with no or low earning capacity. The problem turns around the question whether one's freedom consists in the (...) access one has to a share of the social product or in the measure of economic self-sufficiency one enjoys. Accordingly the role of private property in external resources as a condition for freedom is unclear: is it the basis of people's capacity for self-determination or is it the basis of people's bargaining power? Van Parijs' commitment to self-ownership suggests the former, his commitment to solidarity suggests the latter. A similar ambivalence is pointed out in his argument for a universal basic income, for which Real Freedom for All is so well-known. (shrink)

This book is dedicated to clarify ambiguous concepts from the world of creativity and innovation. One of the initial triggers for the development of the book was the perceived ambiguity of the binomials Design vs. Design Thinking and Innovation vs. Invention. Frequently, designers and innovation consultants are questioned by their clients about the relationships between these kind of concepts. Has the second emerged through the first, or vice-verse? Is one part of the other? Where are the similarities and which are (...) the differences? This conceptual incomprehension makes itself noticeable between many ambiguous concepts in the world of innovation and creativity. What is the difference between Radical and Disruptive Innovation? Or is Social Innovation the same as Social Intervention? And regarding Creativity, are Creativity and Creative Thinking the same? In this book the reader will find answers to these kinds of questions and doubts. 28 authors from 10 different countries and cultural backgrounds are questioning current definitions and perceptions, by comparing different sources and ideas, or simply by giving their personal opinions. Some of the authors have an academic background, others a practical one, being either entrepreneurs, working with innovation in companies, or being innovation/design consultants. (shrink)

Despite the incremental nature of Dynamic Syntax, the semantic grounding of it remains that of predicate logic, itself grounded in set theory, so is poorly suited to expressing the rampantly context-relative nature of word meaning, and related phenomena such as incremental judgements of similarity needed for the modelling of disambiguation. Here, we show how DS can be assigned a compositional distributional semantics which enables such judgements and makes it possible to incrementally disambiguate language constructs using vector space semantics. Building on (...) a proposal in our previous work, we implement and evaluate our model on real data, showing that it outperforms a commonly used additive baseline. In conclusion, we argue that these results set the ground for an account of the non-determinism of lexical content, in which the nature of word meaning is its dependence on surrounding context for its construal.

An important challenge when creating automatically processable laws concerns open-textured terms. The ability to measure open-texture can assist in determining the feasibility of encoding regulation and where additional legal information is required to properly assess a legal issue or dispute. In this article, we propose a novel conceptualisation of open-texture with the aim of determining the extent of open-textured terms in legal documents. We conceptualise open-texture as a lever whose state is impacted by three types of forces: internal forces (the (...) words within the text themselves), external forces (the resources brought to challenge the definition of words), and lateral forces (the merit of such challenges). We tested part of this conceptualisation with 26 participants by investigating agreement in paired annotators. Five key findings emerged. First, agreement on which words are open-texture within a legal text is possible and statistically significant. Second, agreement is even high at an average inter-rater reliability of 0.7 (Cohen’s kappa). Third, when there is agreement on the words, agreement on the Open-Texture Value is high. Fourth, there is a dependence between the Open-Texture Value and reasons invoked behind open-texture. Fifth, involving only four annotators can yield similar results compared to involving twenty more when it comes to only flagging clauses containing open-texture. We conclude the article by discussing limitations of our experiment and which remaining questions in real life cases are still outstanding. (shrink)

In this paper, we use the risk apportionment technique of Eeckhoudt, Rey and Schlesinger (2007) to study higher order risk preferences for others’ health as well as ex-ante and ex-post inequality preferences for social risky distributions, and their interaction. In an experiment on a sample of university students acting as impartial spectators, we observe risk aversion towards social health losses and a dislike of ex-ante inequality. In addition, evidence for ex-post inequality seeking is much weaker than evidence for ex-ante inequality (...) aversion. Because ex-ante inequality aversion is unrelated to risk aversion, we conclude that simple forms of utilitarianism are not relevant for individual judgment of social risk over health. Last, our investigation of precautionary distribution, which would occur when one particular group in the society suffers from background health risk, shows substantial polarization of preferences.

We report an experiment where each subject’s ambiguity sensitivity is measured by an ambiguity premium, a concept analogous to and comparable with a risk premium. In our design, some tasks feature known objective risks and others uncertainty about which subjects have imperfect, heterogeneous, information. We show how the smooth ambiguity model can be used to calculate ambiguity premia. A distinctive feature of our approach is estimation of each subject’s subjective beliefs about the uncertainty in ambiguous tasks. We find considerable heterogeneity (...) among subjects in beliefs and ambiguity premia; and that, on average, ambiguity sensitivity is about as strong as risk sensitivity. (shrink)

Statements are always under the threat of the potential counter-question How do you know? To pre-empt this question, language users often indicate what kind of access they had to the communicated content: Their own perception, inference from other information, 'hearsay', etc. Such expressions, grammatical or lexical, have been studied in recent years under the cover term of evidentiality research. The present volume contributes 11 new studies to this flourishing field, all exploring evidential phenomena in a range of languages (Dutch, Estonian, (...) Finnish, French, German, Khalkha Mongolian, Spanish, Tibetan, Yurakaré), using a variety of methodologies. Evidential meaning is discussed in relation to other semantic dimensions, such as epistemic modality, semantic roles, commitment, quotative meaning, and tense. The volume is of interest to scholars and students who are interested in up-to-date methods and frameworks for studying evidential meaning and the various ways it is expressed in the languages of the world.

Recent work on compositional distributional models shows that bialgebras over finite dimensional vector spaces can be applied to treat generalised quantifiersGeneralised quantifiers for natural language. That technique requires one to construct the vector space over powersets, and therefore is computationally costly. In this paper, we overcome this problem by considering fuzzy versions of quantifiers along the lines of ZadehZadeh, L. A., within the category of many valued relationsMany valued relations. We show that this category is a concrete instantiation of the (...) compositional distributional model. We show that the semantics obtained in this model is equivalent to the semantics of the fuzzy quantifiers of ZadehZadeh, L. A.. As a result, we are now able to treat fuzzy quantification without requiring a powerset construction. (shrink)

In recent years, there has been a significant increase in research on mediated communication via social touch. Previous studies indicated that mediated social touch can induce similar positive outcomes to interpersonal touch. However, studies investigating the user experience of MST technology predominantly involve brief experiments that are performed in well-controlled laboratory conditions. Hence, it is still unknown how MST affects the relationship and communication between physically separated partners in a romantic relationship, in a naturalistic setting and over a longer period (...) of time. In a longitudinal explorative field study, the effects of MST on social connectedness and longing for touch among geographically separated romantic couples were investigated in a naturalistic setting. For 2 weeks, 17 couples used haptic bracelets, that were connected via the internet, to exchange mediated squeeze-like touch signals. Before and after this period, they reported their feelings of social connectedness and longing for touch through questionnaires. The results show that the use of haptic bracelets enhanced social connectedness among geographically separated couples but did not affect their longing for touch. Interviews conducted at the end of the study were analyzed following the thematic analysis method to generate prominent themes and patterns in using MST technology among participant couples. Two main themes were generated that captured the way the bracelets fostered a positive one-to-one connection between partners and the way in which participants worked around their frustrations with the bracelets. Detailed findings and limitations of this longitudinal field study are further discussed, and suggestions are made for future research. (shrink)
