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)

John Pell worked in the Netherlands from 1643 until 1652. He therefore deserves a place in a survey of mathematics c. 1650 in the Netherlands. During his stay he was mainly concerned with refuting a quadrature of the circle that was published in 1644 in Amsterdam by the Danish astronomer and mathematician Longomontanus. We therefore make Pell's refutation the main theme of this paper, but other aspects of Pell's work and some biographical information will be discussed within this framework. This (...) paper includes a discussion of the refuted quadrature, and the first publication of a copy of the original one-leaf refutation, which was thought to be lost. In addition, we survey Pell's correspondence about the affair and in that connection discuss some unknown letters from Mersenne. (shrink)

Between‐trial effects in Stroop‐like interference tasks are linked to differences in the amount of cognitive control. Trials following an incongruent trial show less interference, an effect suggested to result from the increased control caused by the incongruent previous trial (known as the Gratton effect). In this study, we show that cognitive control not only results in a different amount of interference but also in a different locus of the interference. That is, the stage of the task that shows the most (...) interference changes as a function of the preceding trial. Using computational cognitive modeling, we explain these effects by a difference in the amount of processing of the irrelevant dimension of the stimulus. (shrink)

This article discusses how sequential sampling models can be integrated in a cognitive architecture. The new theory Retrieval by Accumulating Evidence in an Architecture (RACE/A) combines the level of detail typically provided by sequential sampling models with the level of task complexity typically provided by cognitive architectures. We will use RACE/A to model data from two variants of a picture–word interference task in a psychological refractory period design. These models will demonstrate how RACE/A enables interactions between sequential sampling and long-term (...) declarative learning, and between sequential sampling and task control. In a traditional sequential sampling model, the onset of the process within the task is unclear, as is the number of sampling processes. RACE/A provides a theoretical basis for estimating the onset of sequential sampling processes during task execution and allows for easy modeling of multiple sequential sampling processes within a task.

The speed‐accuracy trade‐off (SAT) effect refers to the behavioral trade‐off between fast yet error‐prone respones and accurate but slow responses. Multiple theories on the cognitive mechanisms behind SAT exist. One theory assumes that SAT is a consequence of strategically adjusting the amount of evidence required for overt behaviors, such as perceptual choices. Another theory hypothesizes that SAT is the consequence of the mixture of multiple categorically different cognitive processes. In this paper, these theories are disambiguated by assessing whether the fixed‐point (...) property of mixture distributions holds, in both simulations and data. I conclude that, at least for perceptual decision making, there is no evidence for a mixture of different cognitive processes to trade off accuracy of responding for speed. (shrink)

According to logical theories of meaning, a meaning of an expression can be formalized and encoded in truth conditions. Vagueness of the language and individual differences between people are a challenge to incorporate into the meaning representations. In this paper, we propose a new approach to study truth-conditional representations of vague concepts. For a case study, we selected two natural language quantifiers most and more than half. We conducted two online experiments, each with 90 native English speakers. In the first (...) experiment, we tested between-subjects variability in meaning representations. In the second experiment, we tested the stability of meaning representations over time by testing the same group of participants in two experimental sessions. In both experiments, participants performed the verification task. They verified a sentence with a quantifier (e.g., “Most of the gleerbs are feezda.”) based on the numerical information provided in the second sentence, (e.g., “60% of the gleerbs are feezda”). To investigate between-subject and within-subject differences in meaning representations, we proposed an extended version of the Diffusion Decision Model with two parameters capturing truth conditions and vagueness. We fit the model to responses and reaction times data. In the first experiment, we found substantial between-subject differences in representations of most as reflected by the variability in the truth conditions. Moreover, we found that the verification of most is proportion-dependent as reflected in the reaction time effect and model parameter. In the second experiment, we showed that quantifier representations are stable over time as reflected in stable model parameters across two experimental sessions. These findings challenge semantic theories that assume the truth-conditional equivalence of most and more than half and contribute to the representational theory of vague concepts. The current study presents a promising approach to study semantic representations, which can have a wide application in experimental linguistics. (shrink)

A letter written by Christiaan Huygens to David Gregory is published here for the first time. After an introduction about the contacts between the two correspondents, an annotated English translation of the letter is given. The letter forms part of the wider correspondence about the ‘new calculus’, in which L'Hospital and Leibniz also participated, and gives some new evidence about Huygens's ambivalent attitude towards the new developments. Therefore, two mathematical passages in the letter are discussed separately. An appendix contains the (...) original Latin text. (shrink)

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.

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.

Parametric cognitive models are increasingly popular tools for analyzing data obtained from psychological experiments. One of the main goals of such models is to formalize psychological theories using parameters that represent distinct psychological processes. We argue that systematic quantitative reviews of parameter estimates can make an important contribution to robust and cumulative cognitive modeling. Parameter reviews can benefit model development and model assessment by providing valuable information about the expected parameter space, and can facilitate the more efficient design of experiments. (...) Importantly, parameter reviews provide crucial—if not indispensable—information for the specification of informative prior distributions in Bayesian cognitive modeling. From the Bayesian perspective, prior distributions are an integral part of a model, reflecting cumulative theoretical knowledge about plausible values of the model's parameters (Lee,2018). In this paper we illustrate how systematic parameter reviews can be implemented to generate informed prior distributions for the Diffusion Decision Model (DDM; Ratcliff and McKoon,2008), the most widely used model of speeded decision making. We surveyed the published literature on empirical applications of the DDM, extracted the reported parameter estimates, and synthesized this information in the form of prior distributions. Our parameter review establishes a comprehensive reference resource for plausible DDM parameter values in various experimental paradigms that can guide future applications of the model. Based on the challenges we faced during the parameter review, we formulate a set of general and DDM-specific suggestions aiming to increase reproducibility and the information gained from the review process.

The parameters governing our behavior are in constant flux. Accurately capturing these dynamics in cognitive models poses a challenge to modelers. Here, we demonstrate a mapping of ACT-R's declarative memory onto the linear ballistic accumulator (LBA), a mathematical model describing a competition between evidence accumulation processes. We show that this mapping provides a method for inferring individual ACT-R parameters without requiring the modeler to build and fit an entire ACT-R model. Existing parameter estimation methods for the LBA can be used, (...) instead of the computationally expensive parameter sweeps that are traditionally done. We conduct a parameter recovery study to confirm that the LBA can recover ACT-R parameters from simulated data. Then, as a proof of concept, we use the LBA to estimate ACT-R parameters from an empirical dataset. The resulting parameter estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals. In addition, we find that the mapping between ACT-R and LBA lends a more concrete interpretation to ACT-R's latency factor parameter, namely as a measure of response caution. This work contributes to a growing movement towards integrating formal modeling approaches in cognitive science. (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.

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.

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)

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)

Wie ‘Mill’ zegt, zegt in eerste instantie bovenal ‘vrijheid’ en ‘utilisme’. In hun onderling verband vormen deze begrippen nog steeds een sterke verwoording van het zelfbegrip van de moderne mens. In de maakbare, nieuwe wereld van het modernisme ervaart de mens de mogelijkheid en wenselijkheid, de wereld naar eigen inzicht en ontwerp in te richten. Daarbij verlangt hij zo veel mogelijk verschoond blijven van onderdrukkende, traditionele, paternalistische machten, of die nu van de overheid komen of uit de samenleving. Richtsnoer vormt (...) niet meer louter de morele wet die hij zichzelf oplegt, of door anderen opgelegd krijgt, maar het systeem van sociale wetten zoals dat wordt geformuleerd in de positieve wetenschap: de economie en de sociologie.

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)

Van Oenen stuit op een opvallende paradox: democratie wordt niet bedreigd door mensen die tegen democratie zijn, maar juist door degenen die zeer enthousiast zijn over de democratie. Wij lijken nooit genoeg democratie te hebben. Dit is een motor voor veel van de democratische onvrede die vandaag de dag door velen ervaren wordt. Maar de democratie is eigenlijk volledig gerealiseerd, zo stelt Van Oenen, en begint inmiddels vormen van slijtage te vertonen. Het lastige aan een volledig gerealiseerde democratie is dat (...) het steeds moeilijker wordt de bestuurders verwijten te maken over zaken die niet goed lopen. Wij zijn in dat geval immers zelf medeschuldig, want wij hebben deze mensen verkozen. Volgens Van Oenen is ook dit een belangrijke motor van ontevredenheid. (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)

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.

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.
