AbstractIn most social species, position in the male social hierarchy and reproductive success are positively correlated; in humans, however, this relationship is less clear, with studies of traditional societies yielding mixed results. In the most economically advanced human populations, the adaptiveness of status vanishes altogether; social status and fertility are uncorrelated. These findings have been interpreted to suggest that evolutionary principles may not be appropriate for the explanation of human behavior, especially in modern environments. The present study tests the adaptiveness of social status with actual mating and reproductive data in a representative sample of males from an industrial society. Reproductive success, even when assessed by a more reliable measure ofactualmale fertility than the one commonly used, fails to correlate with social status. In striking contrast, however, status is found to be highly correlated withpotentialfertility, as estimated from copulation frequency. Status thus accounts for as much as 62% of the variance in thisproximatecomponent of fitness. This pattern is remarkably similar to what is found in many traditional societies and would result in a substantial positive relationship between cultural and reproductive success in industrial populations were it not for the novel conditions imposed by contraception and monogamy. Various underlying mechanisms are suggested for these findings, illustrating the value of current behavioral and reproductive data in the study of adaptation. It is concluded that evolutionary explanations of human behavior remain entirely relevant in modern societies.

Western psychology tends to be divisive in dealing with human personality and has been responsible for the nature-versus nurture controversy. On the one hand, it contends that certain corrupt behavior is predetermined by psychological or biological factors from conception—while on the other, it explains behavior as a simplistic series of reinforcements from contingencies and conditioned responses to environmental stimuli. This secular humanistic outlook has produced an ethical relativism that is the current trend in today’s world. This stance is not condemned only by Islam, but also by most religions of the world. This shows that the human nature (fitrah) is still vibrant and dynamic. This article attempts to highlight the importance of the Islamic belief system—which is an integrated and comprehensive way in dealing with human behavior—especially by means of the interaction of nature, nurture, and the spiritual factor in the formation of human behavior.

Evolutionary psychology and behavioral endocrinology provide complementary perspectives on interpreting human behavior and psychology. Hormones can function as underlying mechanisms that influence behavior in functional ways. Understanding these proximate mechanisms can inform ultimate explanations of human psychology. This chapter introduces this edited volume by first discussing evolutionary perspectives in behavioral endocrinology. It then briefly addresses three broad topic areas of behavioral endocrinology: (1) development and survival, (2) reproductive behavior, and (3) social and affective behavior. It provides examples of research within each of these areas and describes potential adaptations. The chapter concludes with a discussion on the importance of integrating mechanisms with function when investigating human behavior and psychology.

This article contributes to the debate between the merits of the ‘politics of presence’ versus the ‘politics of ideas’ by examining the case of the first female Korean president, Park Geun-Hye. On the one hand, Park did not represent ‘the ideas’ of feminist politics. While her gender identity was widely propagated and accepted, it did not transform into deliberate identity-based politics. On the other hand, she contributed to the elevation of women’s social status through various unintended consequences, although Park’s ‘femininity without feminism’ inevitably led to the negligence of gender politics in her government. Indeed, Park’s existence, rather than her intention, stimulated the debate on the role and status of women in Korean society and enabled the rise of a number of first females in various sectors. In sum, the ‘politics of presence’ was triggered even without overt political measures.

In many social species, there are important connections between social behaviour and reproduction that provide critical insights into the evolution of sociality. In this study, we describe associations between agonistic behaviour and male reproductive success in stable social groups of bluebanded gobies (Lythrypnus dalli). This highly social, sex-changing species forms linear hierarchies of a dominant male and multiple subordinate females. Males reproduce with each female in the harem and care for the eggs. Since aggression tends to be associated with reduced reproduction in social hierarchies, we hypothesized that males in groups with high rates of aggression would fertilise fewer eggs. We also hypothesized that a male’s agonistic behaviour would be associated with his reproductive success. Dominants often exert substantial control over their harem, including control over subordinate reproduction. To address these hypotheses, we quantified egg laying/fertilisation over 13 days and observed agonistic behaviour. We show that there was a significant, negative association between male reproductive success and the total rate agonistic interactions by a group. While no male behaviours were associated with the quantity of eggs fertilised, female agonistic behaviour may be central to male reproductive success. We identified a set of models approximating male reproductive success that included three female behaviours: aggression by the highest-ranking female and approaches by the lowest-ranking female were negatively associated with the quantity of eggs fertilised by males in their groups, but the efficiency with which the middle-ranking female displaced others was positively associated with this measure. These data provide a first step in elucidating the behavioural mechanisms that are associated with L. dalli reproductive success.

Tässä artikkelissa tarkastellaan, kuinka Suomen ja Unkarin pääministereitä puhutellaan Facebookissa. Tutkimuksen kohteena on se, mitä puhuttelukeinoja kommentoijat käyttävät kahdessa eri tarkoituksessa: toisaalta sympatian tai samaa mieltä olemisen, toisaalta erimielisyyden tai kritiikin ilmaisemisessa. Kahden sukukielen, suomen ja unkarin, puhuttelukeinot ovat samankaltaisia, mutta niiden käytössä on huomattavia eroja esimerkiksi sinuttelun ja teitittelyn yleisyydessä. Aineistona on viiteen Suomen pääministeri Juha Sipilän ja yhdeksään Unkarin pääministeri Viktor Orbánin vuosina 2015–2017 kirjoittamaan Facebook-päivitykseen tulleita kommentteja. Tarkastelun kohteena on 189 suomenkielistä ja 191 unkarinkielistä puhuttelumuotoa sisältävää kommenttia. Kommentit on jaettu myötäileviin ja vastustaviin ja näitä kahta kommenttityyppiä tarkastellaan kvantitatiivisesti ja kvalitatiivisesti pyrkimyksenä selvittää, mitä eroja puhuttelumuodon valinnassa ilmenee. Tutkimuksen teoreettis-metodisena taustana on aiempi sosiopragmaattinen puhuttelututkimus. Tutkimus osoittaa, että suomessa sinuttelu on hyvin yleistä riippumatta kommentin laadusta, mutta unkarissa sinuttelu on tavallisesti erimielisyyden osoittamisen keino. Tyypillinen kannustavan kommentin kirjoittaja käyttää suomessa sinuttelua ja pääministerin etunimeä, unkarissa teitittelyä, ön-teitittelypronominia ja pääministerin titteliä. Unkarin kielessä puhuteltavan yhteiskunnallinen asema vaikuttaakin puhuttelumuodon valintaan vahvemmin kuin suomessa. Toissijaisena strategiana unkarissa esiintyy jonkin verran myös uudenlaista kunnioittavaa sinuttelua yhdistettynä pääministerin etunimen käyttöön. Suomenkielisen aineiston vastustavissa kommenteissa esiintyy vielä todennäköisemmin sinuttelua kuin myötäilevissä kommenteissa sekä sinä-pronominia ja pääministerin sukunimeä, unkarinkielisessä aineistossa puolestaan sinuttelua, te ’sinä’ -pronominia ja pääministerin etu- tai sukunimeä tai nimenmuunnoksia. Toissijaisena strategiana joissain unkarin vastustavissa kommenteissa hyödynnetään ylikohteliaisuutta ja intentionaalista inkoherenssia. Aineiston perusteella näyttää siltä, että Facebook-kommenteissa käytetään suomessa etupäässä sinuttelua samoin kuin muissakin internetkeskusteluissa; kommentoijien mielipiteen ilmaisemisessa nominaalisilla puhuttelumuodoilla on tärkeä rooli. Unkarissa taas internetin yleisestä sinuttelupainotteisuudesta huolimatta tärkeimpänä keinona on sinuttelun ja teitittelyn vastakkainasettelu.   How to address a Prime Minister? Forms of address in comments to posts from the Prime Ministers of Finland and Hungary This article examines how the Prime Ministers of Finland and Hungary are addressed on Facebook. The aim of the study is to investigate which forms of address are used by commentators expressing, on the one hand, sympathy or consent, and on the other, disagreement or criticism. The repertoires of address forms of these two related languages, Finnish and Hungarian, bear many similarities, but the frequency and status of these forms are different. The data consists of comments on five posts written by Prime Minister of Finland Juha Sipilä and on nine posts written by Prime Minister of Hungary Viktor Orbán between 2015–2017, comprising a total of 189 comments in Finnish and 191 comments in Hungarian, all containing forms of address. The comments have been divided into two types: comments showing sympathy and comments showing disagreement or criticism. These two comment types have been analysed quantitatively and qualitatively aiming to determine how the address practices employed differ from each other. The theoretical background of this study is based upon previously conducted socio­pragmatic address research. The article shows that the use of T forms  is very common in Finnish, regardless of the type of comment, but that in Hungarian, T forms are typically used as a linguistic tool to express disagreement. In Finnish, a typical commentator showing sympathy will use T forms and address the Prime Minister by his first name, whereas in Hungarian V forms, the V form pronoun ön, and the title ‘Prime Minister’ are favoured. The social status of the addressee has a stronger effect on the choice of address forms in Hungarian than it does in Finnish. However, some Hungarian comments include a new, respectful type of T form used with the first name of the Prime Minister. In comments expressing disagreement in the Finnish data, writers favour T forms, especially T form pronouns, and the use of the Prime Minister’s surname, whereas in the Hungarian data T forms, the T form pronoun te ‘you’ and the use of the Prime Minister’s first name, surname or nicknames are the most typical address practices. In conclusion, commentators in the Finnish data seem to use mostly T forms on Facebook, thus imitating address practices common in other online conversations. Instead of the T/V opposition, nominal forms of address play an important role in expressing the commentators’ attitude. In the Hungarian data, despite the prevalence of the T forms in online chats, the most important resource in expressing relation to the Prime Minister seems to be the contrast between the T and V forms, reflecting their significant status in Hungarian.

Psychophysical studies suggest that different colors have different perceptual status: red and blue for example are thought of as elementary sensations whereas yellowish green is not. The dominant account for such perceptual asymmetries attributes them to specificities of the neuronal representation of colors. Alternative accounts involve cultural or linguistic arguments. What these accounts have in common is the idea that there are no asymmetries in the physics of light and surfaces that could underlie the perceptual structure of colors, and this is why neuronal or cultural processes must be invoked as the essential underlying mechanisms that structure color perception. Here, we suggest a biological approach for surface reflection properties that takes into account only the information about light that is accessible to an organism given the photopigments it possesses, and we show that now asymmetries appear in the behavior of surfaces with respect to light. These asymmetries provide a classification of surface properties that turns out to be identical to the one observed in linguistic color categorization across numerous cultures, as pinned down by cross cultural studies. Further, we show that data from psychophysical studies about unique hues and hue cancellation are consistent with the viewpoint that stimuli reported by observers as special are those associated with this singularity-based categorization of surfaces under a standard illuminant. The approach predicts that unique blue and unique yellow should be aligned in chromatic space while unique red and unique green should not, a fact usually conjectured to result from nonlinearities in chromatic pathways.

To Darwin, parasites were fascinating examples of adaptation but their significance as selective factors for a wide range of phenomena has only been studied in depth over the last few decades. This work has had its roots in behavioural/evolutionary ecology on the one hand, and in population biology/ecology on the other, thus shaping a new comprehensive field of ‘evolutionary parasitology’. Taking parasites into account has been a success story and has shed new light on several old questions such as sexual selection, the evolution of sex and recombination, changes in behaviour, adaptive life histories, and so forth. In the process, the topic of ecological immunology has emerged, which analyses immune defences in a framework of costs and benefits. Throughout, a recurrent theme is how to appropriately integrate the underlying mechanisms as evolved boundary conditions into a framework of studying the adaptive value of traits. On the conceptual side, major questions remain and await further study.

If the concept of “free will” is reduced to that of “choice” all physical world share the latter quality. Anyway the “free will” can be distinguished from the “choice”: The “free will” involves implicitly a certain goal, and the choice is only the mean, by which the aim can be achieved or not by the one who determines the target. Thus, for example, an electron has always a choice but not free will unlike a human possessing both. Consequently, and paradoxically, the determinism of classical physics is more subjective and more anthropomorphic than the indeterminism of quantum mechanics for the former presupposes certain deterministic goal implicitly following the model of human freewill behavior. Quantum mechanics introduces the choice in the fundament of physical world involving a generalized case of choice, which can be called “subjectless”: There is certain choice, which originates from the transition of the future into the past. Thus that kind of choice is shared of all existing and does not need any subject: It can be considered as a low of nature. There are a few theorems in quantum mechanics directly relevant to the topic: two of them are called “free will theorems” by their authors (Conway and Kochen 2006; 2009). Any quantum system either a human or an electron or whatever else has always a choice: Its behavior is not predetermined by its past. This is a physical law. It implies that a form of information, the quantum information underlies all existing for the unit of the quantity of information is an elementary choice: either a bit or a quantum bit (qubit).

Abstract Background In the context of the COVID-19 emergency, the concern has been raised that people may compensate the reduction in risk ensured by mask use with an increase in risk induced by lower adherence to physical distancing rules. Purpose The paper investigates if people compensate risk in this manner when their interaction partner wears a face mask, examining if risk compensation further depends on gender, signaled social status and perceived race. Methods An experiment was conducted in two waves (June, n = 1396 and September 2020, n = 1326) in front of the traffic lights of four busy roads in Paris. A confederate asked a randomly selected pedestrian for directions following a script and keeping the recommended distance. Confederates were locally recognizable as Blacks or Whites and alternatively presented themselves with a costume indicative of high or low social status. An observer recorded whether the pedestrian kept the recommended distance. Results Both in June and September, men are less likely to comply with the distancing rule when the confederate wears the face mask, and particularly so when the confederate signals high status. When the confederate wears the mask, female pedestrians observe less the one-meter rule in September than in June. Conclusions Men’s risk compensatory behavior is constant over time. In contrast, women’s depends on the time period.
