This article analyzes local algorithmic practices resulting from the increased use of time-lapse (TL) imaging in fertility treatment. The data produced by TL technologies are expected to help professionals pick the best embryo for implantation. The emergence of TL has been characterized by promissory discourses of deeper embryo knowledge and expanded selection standardization, despite professionals having no conclusive evidence that TL improves pregnancy rates. Our research explores the use of TL tools in embryology labs. We pay special attention to standardization (...) efforts and knowledge-creation facilitated through TL and its incorporated algorithms. Using ethnographic data from five UK clinical sites, we argue that knowledge generated through TL is contingent upon complex human–machine interactions that produce local uncertainties. Thus, algorithms do not simply add medical knowledge. Rather, they rearrange professional practice and expertise. Firstly, we show how TL changes lab routines and training needs. Secondly, we show that the human input TL requires renders the algorithm itself an uncertain and situated practice. This, in turn, raises professional questions about the algorithm’s authority in embryo selection. The article demonstrates the embedded nature of algorithmic knowledge production, thus pointing to the need for STS scholarship to further explore the locality of algorithms and AI. (shrink)

A number of theories about the origins of musicality have incorporated biological and social perspectives. Darwin argued that musicality evolved by sexual selection, functioning as a courtship display in reproductive partner choice. Darwin did not regard musicality as a sexually dimorphic trait, paralleling evidence that both sexes produce and enjoy music. A novel research strand examines the effect of musicality on sexual attraction by acknowledging the importance of facial attractiveness. We previously demonstrated that music varying in emotional content increases the (...) perceived attractiveness and dating desirability of opposite-sex faces only in females, compared to a silent control condition. Here, we built upon this approach by presenting the person depicted (target) as the performer of the music (prime), thus establishing a direct link. We hypothesized that musical priming would increase sexual attraction, with high-arousing music inducing the largest effect. Musical primes (25 s, piano solo music) varied in arousal and pleasantness, and targets were photos of other-sex faces of average attractiveness and with neutral expressions (2 s). Participants were 35 females and 23 males (heterosexual psychology students, single, and no hormonal contraception use) matched for musical background, mood, and liking for the music used in the experiment. After musical priming, females’ ratings of attractiveness and dating desirability increased significantly. In males, only dating desirability was significantly increased by musical priming. No specific effects of music-induced pleasantness and arousal were observed. Our results, together with other recent empirical evidence, corroborate the sexual selection hypothesis for the evolution of human musicality. (shrink)

Foreign language education in the twenty-first century still teaches vocabulary mainly through reading and listening activities. This is due to the link between teaching practice and traditional philosophy of language, where language is considered to be an abstract phenomenon of the mind. However, a number of studies have shown that accompanying words or phrases of a foreign language with gestures leads to better memory results. In this paper, I review behavioral research on the positive effects of gestures on memory. Then (...) I move to the factors that have been addressed as contributing to the effect, and I embed the reviewed evidence in the theoretical framework of embodiment. Finally, I argue that gestures accompanying foreign language vocabulary learning create embodied representations of those words. I conclude by advocating the use of gestures in future language education as a learning tool that enhances the mind. (shrink)

In this paper we introduce a new generation of language trainers: intelligent virtual agents (IVAs) with human appearance and the capability to teach foreign language vocabulary. We report results from studies that we have conducted with Billie, an IVA employed as a vocabulary trainer, as well as research findings on the acceptance of the agent as a trainer by adults and children. The results show that Billie can train humans as well as a human teacher can and that both adults (...) and children accept the IVA as a trainer. The advantages of IVAs are multiple. First, their teaching methods can be based on neuropsychological research findings concerning memory and learning practice. Second, virtual teachers can provide individualized training. Third, they coach users during training, are always supportive, and motivate learners to train. Fourth, agents will reside in the user's mobile devices and thus be at the user's disposal everywhere and anytime. Agents in apps will make foreign language training accessible to anybody at low cost. This will enable people around the world, including physically, financially, and geographically disadvantaged persons, to learn a foreign language and help to facilitate multilingualism. (shrink)

We previously showed that owner personality and human-dog relationship predicted the performance of a human-dog dyad in a practical task. Based on the same data set we presently investigate the effects of individual and social factors on the social attraction of dogs to their owners. Twenty-two male and female owners and their intact male dogs were observed during a “picture viewing” test, where we diverted the owner's attention away from their dog whilst it was permitted to move freely around the (...) room. Owner personality axis “neuroticism” and dog personality axis “vocal and aggressive” were, respectively, positively and negatively related to the time the dog stayed in proximity to the owner. Quality of relationship and attachment also had significant effects on this proximity. We conclude that personality and the nature of the human-dog relationship may all influence dogs' social attraction to their owners. (shrink)

All humans share a universal, evolutionarily ancient approximate number system (ANS) that estimates and combines the numbers of objects in sets with ratio-limited precision. Interindividual variability in the acuity of the ANS correlates with mathematical achievement, but the causes of this correlation have never been established. We acquired psychophysical measures of ANS acuity in child and adult members of an indigene group in the Amazon, the Mundurucú, who have a very restricted numerical lexicon and highly variable access to mathematics education. (...) By comparing Mundurucú subjects with and without access to schooling, we found that education significantly enhances the acuity with which sets of concrete objects are estimated. These results indicate that culture and education have an important effect on basic number perception. We hypothesize that symbolic and nonsymbolic numerical thinking mutually enhance one another over the course of mathematics instruction. (shrink)

To date, we know very little about the effects of the differences in attachment classifications on the physiological correlates of stress regulation in adolescent age groups. The present study examined for the first time heart rate and heart rate variability during an attachment interview in adolescents. HR and HRV data were collected during a baseline assessment as well as during the administration of the Adult Attachment Projective Picture System in a community-based sample of 56 adolescents. We additionally used the Adult (...) Attachment Interview in 50% of our sample to test the convergent validity. Adolescents with a secure attachment representation showed a higher HRV from baseline to the AAP interview compared to those with an insecure-dismissing and the unresolved group. A comparison between the two insecure attachment groups showed no significant difference related to HR and HRV. Cohen’s Kappa revealed an almost perfect agreement between the AAP and the AAI for the four-group classification. Our results indicate that adolescents with a secure attachment representation are more capable of dealing with attachment-related distress which is represented in higher HRV during an attachment interview.

Motivated by Kalman residuated lattices, Nelson residuated lattices and Nelson paraconsistent residuated lattices, we provide a natural common generalization of them. Nelson conucleus algebras unify these examples and further extend them to the non-commutative setting. We study their structure, establish a representation theorem for them in terms of twist structures and conuclei that results in a categorical adjunction, and explore situations where the representation is actually an isomorphism. In the latter case, the adjunction is elevated to a categorical equivalence. By (...) applying this representation to the original motivating special cases we bring to the surface their underlying similarities. (shrink)

Although we are beginning to understand the neurocognitive processes that underlie the emergence of dreaming, what accounts for the bizarre phenomenology of dreams remains debated. I address this question by comparing dreaming with waking mind wandering and challenging previous accounts that utilize bizarreness to mark a sharp divide between conscious experiences in waking and sleeping. Instead, I propose that bizarreness is a common, non-deficient feature of spontaneous offline simulations occurring across the sleep-wake cycle and can be tied to the specific (...) characteristics of spontaneous thought as being dynamic, unconstrained, (hyper)associative and highly variable in content. Rather than misrepresenting waking reality, bizarreness can be employed to investigate the very building blocks of spontaneous cognition. The absence of bizarreness in thought processes is imposed by automatic and deliberate cognitive constraints. By contrast, thought and memory processes operating on their own without such constraints are inherently marked by different degrees and types of bizarreness. (shrink)

This paper aims to contribute to an integrated understanding of what goes missing in adverse meditation experiences and in cases of depersonalization disorder. Depersonalization disorder is characterized by distressing alterations in, and sometimes the complete disappearance of, the 'I'-sense. This paper examines the nature of the 'I'-sense and what it means to lose it from a Buddhist perspective. We argue for a nihilist position that the loss of the sense of self arises from misidentifications of the psychophysical complex with non-self (...) elements, such as memories, thoughts, or body movements. Drawing from meditation experiences and depersonalization symptoms, we propose that the sense of self is not a static entity given in experience but fluctuates between various senses of self (and no-self) depending on circumstances. This pluralistic understanding of the various senses of self offers a more nuanced understanding of symptoms in depersonalization disorder and adverse effects of meditation practices. (shrink)

The purpose of this paper is to uncover some of the limitations that critical contextual empiricism, and in particular Longino's contextualism, faces when trying to provide a normative account of scientific knowledge that is relevant to current scientific research. After presenting the four norms of effective criticism, I show how the norms have limited scope when dealing with cases of current scientific practices. I then present some historical evidence for the claim that the organization of science has changed in recent (...) decades, and I argue that the uncovered limitations emerge from this larger phenomenon. Finally, I conclude by suggesting two ways to overcome the previously uncovered limitations. (shrink)

Gender bias is a recalcitrant problem in academia and society. However, dissent has been created on this issue. We focus on dissenting studies by Stephen J. Ceci and Wendy M. Williams, arguing that they reach conclusions that are unwarranted on the basis of the available evidence and that they ignore fundamental objections to their methodological decisions. Drawing on discussions from other contexts, particularly on manufactured dissent concerning anthropogenic climate change, we conclude that dissent on gender bias substantially contributes to the (...) exacerbation of biases in society and an increasing number of attacks on researchers, making it both epistemically and socially problematic.

A layoff is a threatening yet common event which employees might face at some point in their working lives. In two scenario-based experiments, we investigated which actions of a layoff agent during a dismissal notification meeting may contribute to laid-off employees’ fairness judgments and negative attitudes toward the employer. In general, the extent to which layoff victims were treated with respect was consistently found to increase perceptions of interpersonal and procedural fairness and to mitigate negative attitudes toward the employer. Further (...) results showed that layoff victims preferred to be given an adequate explanation of the reasons for the layoff and to receive notice from the direct supervisor. Relationships between the layoff agent’s actions and layoff victims’ negative attitudes toward the employer were mediated by perceptions of procedural fairness. In addition, delegating the layoff agent’s task to an external consultant increased perceived psychological contract breach. Our findings have important implications for organizational justice research and for the managerial practice of implementing fair layoffs. In particular, small actions, such as treating employees with respect, might be of benefit both to humans and organizations. (shrink)

A study of the conflict between philosophy and poetry in four Platonic dialogues: the Ion, the Symposium, the Republic, and the Sophist.

El concepto de generación, con casi dos siglos de presencia en las Humanidades y las Ciencias Sociales, si bien conserva todo su vigor para la construcción de imaginarios, o simples imágenes, con las que captar la atención, y por tanto reaparece de tanto en tanto, sigue planteando no obstante serios problemas conceptuales, epistemológicos y sobre todo metodológicos, cuando intentamos aplicarlo desde presupuestos positivos en la Sociología, más allá del colorismo de los “estudios culturales”, los “estudios de juventud” o el marketing. (...) El presente trabajo parte expone justamente parte de los problemas encontrados, a nivel teórico, a la hora de intentar una operatividad del concepto en el marco de una investigación, en curso, sobre valores y actitudes medioambientales entre distintas --según se mire-- generaciones, cohortes, momentos del ciclo vital o periodos del curso de vida.
