This article takes an intergenerational lens to the study of fathers. It draws on evidence from two economic and social research council-funded intergenerational studies of fathers, one of which focused on four-generation British families and the other which included new migrant (Polish) fathers. The article suggests both patterns of change and continuity in fatherhood across the generations. It demonstrates how cultural forces and material conditions need to combine to facilitate change in fathers? exercise of agency and how (...) social class and the conditions of being a migrant shape fathers? practices. It argues that in seeking to recast the public debate about parenting, it is necessary to penetrate below the discursive level of talk about parenting to examine the habitual nature of many family practices, an endeavour to which an intergenerational approach is well suited. This approach enabled us to tease out the horizontal pull of within-generation influences on fathers, the vertical pull of inheritance from older to younger generations and the material and cultural conditions of fathers? current locations, all of which shape their practices. This analysis also alerted us to changes in conceptual language ? not only from fatherhood to fathering ? but also to the historical resilience of the concept of childcare as reserved largely for the role and practices of mothers.

In this paper intergenerational dimensions of reproductive behavior are studied within the context of the experience of a mid-sized Spanish town just before and during the demographic transition. Different indicators of reproduction are used in bivariate and multivariate approaches. Fertility shows a small, often statistically significant intergenerational dimension, with stronger effects working through women and their mothers than those stemming from the families of their husbands. These effects are materialized mainly through duration-related fertility variables, are singularly absent for (...) variables such as age at first birth or birth intervals, and are much stronger in the case of firstborn daughters than with later siblings. There is a substantial increase in the strength of intergenerational effects during the course of the demographic transition, most visible in age at last birth and duration of reproduction (between women and their mothers), as well as in the effects working through the families of their husbands. These results underscore the on-going importance of biological dimensions of reproduction as well as the way attitudes toward reproduction are taught within the family. The changes identified in this study suggest that the transmission of values and attitudes became more important for reproductive outcomes during this period of demographic modernization. (shrink)

Culture drives cognitive evolution by supporting the transmission and intergenerational accumulation of skills and knowledge, based on social learning and teaching: Later generations benefit from what their predecessors acquired. Taking a metaperspective on those experimental studies that explore the mechanisms underlying cultural transmission, Caldwell discusses their potential for generating valuable insights, their possible limitations, and their generalizability to other species.

have extremely harmful impacts on an individual’s physical, social and mental health throughout their life-span. Recently, it has been reported that maternal ACEs increase the risk of developmental delay in the offspring across generations. This mini review focuses on the direct relationship between maternal ACEs and child developmental delay, and potential mediators/moderators that associate their relationship. Six studies were identified using three search engines. The results indicated that four out of six studies reported at least one significant direct association between (...) maternal ACEs and child development. Additionally, maternal biological, psychological, and social factors were identified as mediators or moderators. In summary, we identified that maternal ACEs increased the risk of developmental delay in children via biological and psychosocial pathways. Future research should examine potential buffering factors and identify when it is crucial to break the intergenerational transmission. (shrink)

To what extent do the mother's and father's jobs and occupational sex-typing influence the status and sex-typing of their children's occupation at first entry into the labour market? Referring to a database containing 5027 respondents of two merged Dutch surveys held between 1992 and 1995, this study finds that the effect of the mother's occupational status on her daughter's is significant, but smaller than either the effect of father's status on his son's or his daughter's status. The mother's occupational sex-typing (...) is related to her daughter's occupational sex-typing. The more female sex-typed the daughter's occupation, the lower her occupational status. In the same way, the father's occupational sex-typing is related to his son's occupational sex-typing. While the extension of the classical status attainment models by the mother's occupation and occupational sex-typing leads to interesting and new coefficients, the authors conclude that the more elementary classical model is not invalidated by these new perspectives.

The United States relies on uncompensated family caregivers to provide most of the long-term care required by older adults as they age. But such care comes at a significant financial cost to these caregivers in the form of lower lifetime earnings and diminished Social Security retirement benefits, ineligibility for Medicare coverage of their healthcare costs, and minimal retirement savings. To reduce the impact of uncompensated caregiving on the intergenerational transmission of poverty, this paper discusses three possible mechanisms of (...) compensating family caregivers: public payments, deemed wage credits under Social Security, and income tax incentives.

Parents typically favour their own children over others’. For example, most parents invest more time and money in their own children than in other children. This parental partiality is usually regarded as morally permissible, or even obligatory, but it can have undesirable distributive effects. For example, it may create unfair or otherwise undesirable advantages for the favoured child. A number of authors have found it necessary to justify parental partiality in the face of these distributive concerns, and they have typically (...) done so by appealing to features of the parent–child relationship. Parental partiality is said to be justified, despite its undesirable distributive effects, in part because the parent enjoys a special kind of relationship with her child. In this paper, I raise a problem for such relational defences of parental partiality. I report empirical findings suggesting that parental partiality will frequently create advantages—sometimes undesirable—not only for one’s children, but also for one’s more distant descendants; I argue that the creation of these latter advantages stands as much in need of justification as does the creation of advantages for one’s own children; and I claim that existing relational defences do not clearly contain the resources necessary to deliver such a justification. I then examine three possible responses to this problem. (shrink)

A number of tasks have been developed to measure the affective theory of mind, nevertheless, recent studies found that different affective ToM tasks do not correlate with each other, suggesting that further studies on affective ToM and its measurement are needed. More in-depth knowledge of the tools that are available to assess affective ToM is needed to decide which should be used in research and in clinical practice, and how to interpret results. The current study focuses on the Reading the (...) Mind in the Eyes Test primarily to investigate in a sample of 112 children the currently unexplored relationships in middle childhood between performance on the RMET and fluid intelligence. Relationships with receptive vocabulary, age, and sex were also investigated. Moreover, because studying the family's influence on children mentalization could have important implications in developing prevention and treatment interventions, this study offers a novel contribution to the field by exploring the family's influence on children's RMET performance. Although significant positive correlations were found among RMET-C performance, fluid intelligence, and receptive language, regression analysis revealed that fluid intelligence was the only predictor. No family influence was found on children's RMET performance. On the whole, results from the current study offer some support to the hypothesis that RMET-C is not a “pure” ToM task, specifically the effect of fluid intelligence on RMET performance should be taken into account when RMET is used both in research and in the clinical setting.

Recent work on enculturation suggests that our cognitive capacities are significantly transformed in the course of the scaffolded acquisition of cognitive practices such as reading and writing. Phylogenetically, enculturation is the result of the co-evolution of human organisms and their socio-culturally structured cognitive niche. It is rendered possible by evolved cerebral and extra-cerebral bodily learning mechanisms that make human organisms apt to acquire culturally inherited cognitive practices. In addition, cultural learning allows for the intergenerational transmission of relevant (...) knowledge and skills. Ontogenetically, enculturation is associated with neural plasticity and the development of new motor routines and action schemas. It relies on scaffolded learning that structures novice-teacher interactions. The acquisition of reading and writing are paradigm examples of enculturation. Based on an empirically informed analysis of the components of enculturation, I will apply the emerging account of enculturated cognition to narrative practices. To date, research on the impact of narratives on the constitution of the self and our understanding of folk psychology has not paid much attention to the question how narratives are influenced by cumulative cultural evolution and our capacity to acquire reading and writing during ontogeny. I will argue that textual narratives, above and beyond oral narratives, provide genuinely new ways of narration. Therefore, the enculturated interaction with textual narratives has the potential to contribute to a better understanding of ourselves and other cognitive agents. (shrink)

Research on cultural transmission among Americans has established a bias for transmitting stories that have disgusting elements. Conceived of as a cultural evolutionary force, this phenomenon is one type of emotional selection. In a series of online studies with Americans and Indians we investigate whether there are cultural differences in emotional selection, such that the transmission process favours different kinds of content in different countries. The first study found a bias for disgusting content among Americans (...) but not among Indians. Four subsequent studies focused on how country interacts with kind of emotional content in reactions to transmission of stories or information. Whereas Indian participants, compared to Americans, tended to be less interested in, and excited by, transmission of stories and news involving common disgust-elicitors, the opposite pattern held for transmission of happy surprises and good news. We discuss various possible explanations and implications. (shrink)

Cumulative cultural knowledge [CCK], the knowledge we acquire via social learning and has been refined by previous generations, is of central importance to our species’ flourishing. Considering its importance, we should expect that our best epistemological theories can account for how this happens. Perhaps surprisingly, CCK and how we acquire it via cultural learning has only received little attention from social epistemologists. Here, I focus on how we should epistemically evaluate how agents acquire CCK. After sampling some reasons (...) why extant theories cannot account for CCK, I suggest that things aren’t as bleak as they might look. I explain how agents deserve epistemic credit for how CCK is transmitted in cultural learning by promoting a central need of their social group: The efficient and safe transmission of CCK. A good initial fit exists between this observation and Greco’s knowledge-economy framework. Ultimately, however, Greco’s account doesn’t straightforwardly account for CCK because of its strict focus on testimony. I point out two issues in the framework due to this focus. The resulting view advocates giving epistemic credit to agents when they act to promote their communities’ epistemic needs in the right way and highlights the various ways in which agents come to do this.

Culture, defined as shared behavior or information within a community acquired through some form of social learning from conspecifics, is now suggested to act as a second inheritance system. Cultural processes are important in a wide variety of vertebrate species. Birdsong provides a classic example of cultural processes: cultural transmission, where changes in a shared song are learned from surrounding conspecifics, and cultural evolution, where the patterns of songs change through time. This form of (...) class='Hi'>cultural transmission of information has features that are different in speed and form from genetic transmission. More recently, culture, vocal traditions and an extreme form of song evolution has been documented in cetaceans. Humpback whale song ‘revolutions’, where the single population-wide shared song type is rapidly replaced by a new, novel song type introduced from a neighbouring population, represents an extraordinary example of ocean basin-wide cultural transmission rivalled in its geographic extent only by humans. In this review, we examine the cultural evolutions and revolutions present in some birdsong and whale song, respectively. By taking a comparative approach to these cultural processes, we review the existing evidence to understand the similarities and differences for their patterns of expression and the underlying drivers, including anthropogenic influences, which may shape them. Finally, we encourage future studies to explore the role of innovation vs. production errors in song evolution, the fitness information present in song, and how human-induced changes in population sizes, trajectories and migratory connections facilitating cultural transmission may be driving song revolutions.

This paper presents the hypothesis that linguistic capacity evolved through the action of natural selection as an instrument which increased the efficiency of the cultural transmission system of early hominids. We suggest that during the early stages of hominization, hominid social learning, based on indirect social learning mechanisms and true imitation, came to constitute cumulative cultural transmission based on true imitation and the approval or disapproval of the learned behaviour of offspring. A key factor for this (...) transformation was the development of a conceptual capacity for categorizing learned behaviour in value terms - positive or negative, good or bad. We believe that some hominids developed this capacity for categorizing behaviour, and such an ability allowed them to approve or disapprove of their offsprings- learned behaviour. With such an ability, hominids were favoured, as they could transmit to their offspring all their behavioural experience about what can and cannot be done. This capacity triggered a cultural transmission system similar to the human one, though pre-linguistic. We suggest that the adaptive advantage provided by this new system of social learning generated a selection pressure in favour of the development of a linguistic capacity allowing children to better understand the new kind of evaluative information received from parents.

China is experiencing high social inequality accompanying influential education reforms. The Independent Freshmen Admission policy was one of the multiple strategies in higher education reforms in China against the social context of high social inequality and the expansion of higher education. By comparing students admitted through IFA with those admitted by the National College Entrance Examination, we examined how family advantages contributed to higher education inequality in terms of educational opportunity, process, and results. Using data from an elite university in (...) Beijing, we found that: Family advantages improved a student’s likelihood of being admitted through IFA, exhibiting opportunity inequality. No significant difference in academic grades existed between the students admitted through IFA and NCEE. In comprehensive quality, however, those recruited through IFA performed significantly better than those admitted through NCEE. Family social capital not only increased the likelihood of students being admitted through IFA but also, through direct and indirect effects, increased their comprehensive quality performance in terms of receiving student association and social practice awards.

Feminists today are re-imagining nature, biology, and matter in feminist thought and critically addressing new developments in biology, physics, neuroscience, epigenetics and other scientific disciplines. Mattering, edited by noted feminist scholar Victoria Pitts-Taylor, presents contemporary feminist perspectives on the materialist or ‘naturalizing’ turn in feminist theory, and also represents the newest wave of feminist engagement with science. The volume addresses the relationship between human corporeality and subjectivity, questions and redefines the boundaries of human/non-human and nature/culture, elaborates on the entanglements of (...) matter, knowledge, and practice, and addresses biological materialization as a complex and open process. This volume insists that feminist theory can take matter and biology seriously while also accounting for power, taking materialism as a point of departure to rethink key feminist issues. The contributors, an international group of feminist theorists, scientists and scholars, apply concepts in contemporary materialist feminism to examine an array of topics in science, biotechnology, biopolitics, and bioethics. These include neuralplasticity and the brain-machine interface; the use of biometrical identification technologies for transnational border control; epigenetics and the intergenerational transmission of the health effects of social stigma; ADHD and neuropharmacology; and randomized controlled trials of HIV drugs.A unique and interdisciplinary collection, Mattering presents in grounded, concrete terms the need for rethinking disciplinary boundaries and research methodologies in light of the shifts in feminist theorizing and transformations in the sciences.

Many survivors of the Holocaust have carried feelings of shame related to having survived this horrific event. This paper traces a genealogy of shame by exploring the sources of shame that have haunted survivors, and how these have manifested themselves in their lives and the lives of their children. Arguing that the intergenerational transmission of shame has reinforced a culture of silence among survivors and their children, this paper calls for a reconceptualizing of the afterlife of the Holocaust, (...) which leverages shame as a powerful piece of remembering and understanding the Holocaust.

Cet article a pour but de retracer, à partir de l’exemple des étendards polonais du xxe siècle, la genèse et le fonctionnement à travers le temps de cet important support identitaire. L’iconographie et la chromatique vexillologique ont un rôle précis à jouer dans la transmission intergénérationnelle de la mythologie nationale. À partir d’un échantillon thématique de bannières des immigrées polonaises en France, nous nous interrogerons sur l’évolution ou l’immuabilité de cet imaginaire spécifique conditionné non seulement par le temps et (...) l’espace, mais surtout par le besoin collectif de représentation. This article aims to trace selected examples of Polish flags from the 20th century, focusing on their meaning and function, as they were crucial to cultural identity. This is also how the iconography or the color of the flags played an important role in shaping the intergenerational transmission of national and private mythology. Our goal is to show the evolution, as well as the timelessness of this imagery, on the basis of thematically and chronologically circumscribed sets of examples of twentieth century Polish émigré flags from Northern France, where they played an important social and political role.

This article approaches queer history by offering a salutary corrective to dominant cultural and subcultural forces enjoining us to remember. The life-enabling and properly revolutionary effects of actively forgetting the past and, in particular, the legacy of previous generations, are first outlined in readings of Nietzsche, The Aeneid, Freud, Deleuze and Guattari. The localized exercise of an active forgetting is proposed as a response to one especially problematic case of intergenerational transmission in recent French gay and lesbian (...) history: a collective act of self-censorship by the team responsible for the 2002 internet republication of the 1973 ‘cult’ special issue of Recherches, entitled Three Billion Perverts. While the article does not seek to contest the decision to censor these thirty-two pages headed ‘Pédo-Philie’ from the republication, it does take issue with the assumptions underlying the way in which the decision was presented. The article suggests that this act of self-censorship typifies the way in which younger gay and lesbian people of the early twenty-first century are placed in a schizogenic ‘double bind’ by their immediate forebears, radical gays and lesbians of the 1970s, the generation of Guy Hocquenghem and the FHAR; members of the younger generation are told simultaneously to remember and that what they are being told to remember cannot be conveyed to them. The ascesis of an active forgetting is presented as the only way out of this impasse and a necessary emancipating prerequisite for new life and new possibilities. (shrink)

Regional food is grounded in local practices and heritage. With industrialization and post-green revolution threat to food produced within specific region and the associated knowledge has become imminent. Scholars have analyzed the revival of regional foods in different parts of the world. However, there have been limited studies focusing on the revival of regional food from the perspective of food as commons. The paper fills this gap by analyzing the efforts of Morarka-GDC Foundation along with farmers collective in Nawalgarh, India. (...) Employing the framework of commons, we examine how the foundation along with the collective is reviving Shekhawati region’s foods. We used primary and secondary sources to capture the social activities undertaken to sustain the commons. It was found that adopting organic agricultural practices helped in reviving the regional foods by creating and using stock of local resources. Further, social dilemma associated with culinary commons was avoided by creating networks between producers and consumers through _Shekhawati_ festival and Morarka Organics. These practices have resulted in rebuilding the local food system, local tourism, and intergenerational transmission strengthening the local gastronomic identity. However, linking regional food with gastronomic tourism can threaten the local gastronomic culture and survival of authentic regional food. We also find that for a sustained management of the regional foods, scaling-up plays an essential role which has further limitations. (shrink)

Focus on the way in which cultural variants affect other variants' probabilities of transmission in modeling and empirical work can enrich Kline's conceptualization of teaching. For example, the problem of communicating complex cumulative culture is an adaptive problem; teaching methods that manage transmission so that acquisition of some cultural variants increases the probability of acquiring others, provide a partial solution.

Humans have developed the capacity to approve or disapprove of the behavior of their children and of unrelated individuals. The ability to approve or disapprove transformed social learning into a system of cumulative cultural inheritance, because it increased the reliability of cultural transmission. Moreover, people can transmit their behavioral experiences (regarding what can and cannot be done) to their offspring, thereby avoiding the costs of a laborious, and sometimes dangerous, evaluation of different cultural alternatives. Our thesis (...) is that, during ontogeny, the evaluative communication (approval/disapproval) between parents and offspring is substituted by other evaluative communications among peers, like individuals of the same generation. Each person belongs to a reference social group with individuals that interact more intensively. Humans have developed psychological mechanisms that enable cultural transmission by being receptive to parental advice as well as their reference social group. The selective pressure that promoted these new evaluative interactions arose to facilitate the establishment of efficient cooperative relationships. In short, the social control of behavior is essential to understand human cultural transmission. (shrink)

The application of phylogenetic methods to cultural variation raises questions about how cultural adaption works and how it is coupled to cultural transmission. Cultural group selection is of particular interest in this context because it depends on the same kinds of mechanisms that lead to tree-like patterns of cultural variation. Here, we review ideas about cultural group selection relevant to cultural phylogenetics. We discuss why group selection among multiple equilibria is not subject (...) to the usual criticisms directed at group selection, why multiple equilibria are a common phenomena, and why selection among multiple equilibria is not likely to be an important force in genetic evolution. We also discuss three forms of group competition and the processes that cause populations to shift from one equilibrium to another and create a mutation-like process at the group level. (shrink)

In a volume that traverses multiple disciplines, Michael Robbins proposes that the structures of the mind that distinguish us as uniquely human also incline us towards destructive behaviours on a personal and societal level. Psychoanalysis was created by Freud in an effort to understand neurosis and psychosis, the names he gave to individual human destructiveness. His understanding was limited and incorrect because the science of evolution and the disciplines of sociology and cultural anthropology were in their infancy when he (...) formulated his ideas. He did not comprehend that destructiveness is qualitatively different in humans than in other species and he ignored the problem of how biological instincts become mental processes. These limitations left psychoanalysis with one of its most perplexing unsolved problems, the mysterious leap from mind to body. The book explains how neoteny, the prolonged period of post-natal immaturity that distinguishes humans from other animals, requires and enables complex learning from caregivers. It is the knowledge acquired from this learning and its intergenerational transmission that links the biological theory of evolution with the psychosocial theory of psychoanalysis and explains how the human species is unique. The book will be of interest to those who want to learn about how integrating the findings of evolutionary science, primatology, sociology and cultural anthroplogy with the theory of psychoanalysis expands our understanding of what makes humans unique and its implications for the future of our species, and empowers us to influence the destiny of humankind.

Active cultural transmission of fitness-enhancing behavior can be seen as a costly strategy: one for which its evolutionary stability poses a Darwinian puzzle. In this article, we offer a biological market model of cultural transmission that substitutes or complements existing kin selection-based proposals for the evolution of cultural capacities. We demonstrate how a biological market can account for the evolution of teaching when individual learners are the exclusive focus of social learning. We also show how (...) this biological market can affect the dynamics of cumulative culture. The model works best when it is difficult to have access to the observation of the behavior without the help of the actor. However, in contrast to previous non-mathematical hypotheses for the evolution of teaching, we show how teaching evolves, even when innovations are insufficiently opaque and therefore vulnerable to acquisition by emulators via inadvertent transmission. Furthermore, teaching in a biological market is an important precondition for enhancing individual learning abilities. (shrink)

Using samples from three diverse populations, we test evolutionary hypotheses regarding how people reason about the inheritance of various traits. First, we provide a framework for differentiat-ing the outputs of mechanisms that evolved for reasoning about variation within and between biological taxa and culturally evolved ethnic categories from a broader set of beliefs and categories that are the outputs of structured learning mechanisms. Second, we describe the results of a modified “switched-at-birth” vignette study that we administered among children and adults (...) in Puno, Yasawa, and adults in the United States. This protocol permits us to study perceptions of prenatal and social transmission pathways for various traits and to differentiate the latter into vertical versus horizontal cultural influence. These lines of evidence suggest that people use all three mechanisms to reason about the distribution of traits in the population. Participants at all three sites develop expectations that morphological traits are under prenatal influence, and that belief traits are more culturally influenced. On the other hand, each population holds culturally specific beliefs about the degree of social influence on non-morphological traits and about the degree of vertical transmission—with only participants in the United States expecting parents to have much social influence over their children. We reinterpret people's differentiation of trait transmission pathways in light of humans' evolutionary history as a cultural species. (shrink)

Social transmission is at the core of cultural evolutionary theory. It occurs when a demonstrator uses mental representations to produce some public displays which in turn allow a learner to acquire similar mental representations. Although cultural evolutionists do not dispute this view of social transmission, they typically abstract away from the multistep nature of the process when they speak of cultural variants at large, thereby referring both to variation and evolutionary change in mental representations as (...) well as in their corresponding public displays. This conflation suggests that differentiating each step of the transmission process is redundant. In this paper, I examine different forms of interplay between the multistep nature of social transmission and the metric spaces used by cultural evolutionists to measure cultural variation and to model cultural change. I offer a conceptual analysis of what assumptions seem to be at work when cultural evolutionists conflate the complex causal sequence of social transmission as a single space of variation in which populations evolve. To this aim, I use the framework of variation spaces, a formal framework commonly used in evolutionary biology, and I develop two theoretical concepts, ‘technique’ and ‘technical space’, for addressing cases where the complexity of social transmission defies the handy assumption of a single variation space for cultural change.

Atran's account of cultural transmission can be further refined by considering constraints from early-developed, domain-specific intuitive ontological understanding. These suggest specific predictions about the cultural survival of “memes,” depending on the way they activate intuitive understanding. There is no general dynamic of cultural inheritance; only complex predictions for domain-specific competencies that cut across cultural domains.

The articles in this theme issue seek to understand the evolutionary bases of social learning and the consequences of cultural transmission for the evolution of human behaviour.

Introducción: Camagüey ocupa el cuarto lugar nacional en cuanto al número de infectados con VIH/SIDA, después de La Habana, Santiago de Cuba y Holguín. Camagüey se encuentra dentro de los 45 municipios con mayor prevalencia en Cuba. Objetivo: identificar las actitudes socioculturales frente a las infecciones de transmisión sexual en estudiantes de primer año de Medicina. Método: en noviembre de 2011 se realizó un estudio analítico, de corte transversal, a una muestra de estudiantes de la Universidad de Ciencias Médicas "Carlos (...) J. Finlay". Se utilizó una encuesta para recoger información. Con el método no paramétrico de Kruskal Wallis se determinó el nivel de conocimiento de los mismos en cada uno de los componentes relacionados con las actitudes socioculturales. Se utilizó la técnica no paramétrica de ji cuadrado para evaluar si existían diferencias significativas entre los distintos grupos de edades, el sexo y el estado civil. Resultados: se valoró que el componente conductual se encuentra fortalecido, entre otras actitudes, por la tendencia de los estudiantes a mantener parejas estables. En el componente cognitivo sólo un 46 % supo reconocer las vías de transmisión del VIH/SIDA, y un 13,2 % no identificó las manifestaciones clínicas relacionadas con las infecciones de transmisión sexual. En el componente afectivo se destacó un 12 % de los encuestados como grupo de riesgo a los que no les gusta usar el preservativo. Conclusiones: como resultado de la encuesta se lograron identificar algunas actitudes socioculturales frente a las infecciones de transmisión sexual en estudiantes de Medicina de primer año, en los componentes valorados. Background: Camagüey has the fourth national place in the number of persons infected with VHI/AIDS, after Havana, Santiago and Holguín. Objetive: the aim of this work is identifying socio-cultural attitudes to face of the infections of sexual transmission in first year Medicine students. Methods: in November 2011, a group of students participated in a questionnaire. The non-parametric test Kruskal Wallis was made to find significant differences in the answers given by persons with different age, sex or civil status, Frequency of answers to each question was found out. The non parametric technique of Ji square was used to evaluate if there were significant differences among the different groups of ages, the sex and the civil status. Results: it was valued that the behavioral component is strengthened, among other attitudes, for the tendency of the students to maintain stable couples, only a 46 % know most of transmission ways of STD and a 13,2 % know the clinical symptoms, a 12 % said they did not like condom use. Conclusions: it was possible to find with this survey some socio-cultural attitudes to face of the infections of sexual transmission in first year Medicine students. (shrink)

This article introduces an agent-based and a system-dynamics model investigating the cultural transmission of frequent collective rituals. It focuses on social function and cognitive attraction as independently affecting transmission. The models focus on the historical context of early Christian meals, where various theoretically inspiring trends in cultural transmission of rituals can be observed. The primary purpose of the article is to contribute to theorizing about cultural transmission of rituals by suggesting a clear operationalization (...) of their social function and cognitive attraction. Furthermore, the article challenges recent trends in the field by providing a theoretically feasible model for how, under certain conditions, cognitive attraction can influence the transmission to a relatively greater extent than social function. In the system dynamics model we reproduce the results of our agent-based model while putting some of our basic operational assumptions under scrutiny. We consider approaching social function and cognitive attraction in isolation as a preliminary but necessary step in the process of creating more complex models of the cultural selection of rituals, where the two aspects will be combined to produce ritual forms with greater correspondence to real-world religious rituals.

Evolved dispositions influence, but do not determine, how people think about economic problems. The evolutionary cognitive approach offers important insights but underweights the social transmission of ideas as a level of explanation. The need for asocialexplanation for the evolution of economic attitudes is evidenced, for example, by immense variations in folk-economic beliefs over time and across individuals.

Social learning and imitation is central to culture in cetaceans. The training technology used with cetaceans facilitates reinforcing imitation of one dolphin's behavior by another; the same technology, now widely used by pet owners, can lead to imitative learning in such unlikely species as dogs and horses. A capacity for imitation, and thus for cultural learning, may exist in many species.

Information changes as it is passed from person to person, with this process of cultural transmission allowing the minds of individuals to shape the information that they transmit. We present mathematical models of cultural transmission which predict that the amount of information passed from person to person should affect the rate at which that information changes. We tested this prediction using a function-learning task, in which people learn a functional relationship between two variables by observing the (...) values of those variables. We varied the total number of observations and the number of those observations that take unique values. We found an effect of the number of observations, with functions transmitted using fewer observations changing form more quickly. We did not find an effect of the number of unique observations, suggesting that noise in perception or memory may have affected learning. (shrink)

The evidence of high cognitive abilities in cetaceans does not stand up to close scrutiny under the standards established by laboratory researchers. This is likely to lead to a sterile debate between laboratory and field researchers unless fresh ways of taking the debate forward are found. A few suggestions as to how to do this are proposed.

Much recent empirical work in the developmental sciences has emphasized the importance of cultural knowledge transmission for the processes of human evolution and development. This body of empirical work provides indirect support for the “knowledge economy framework” developed by John Greco in his book The Transmission of Knowledge. In doing so, however, it also raises questions concerning the scope or generality of Greco’s framework. Whereas Greco contends that testimonial knowledge transmission is paradigmatic of the process of (...) knowledge transmission generally, this empirical literature recognizes a variety of non-testimonial forms of knowledge transmission, many of which function in ways that are importantly different from outright testimony. This leaves us with some decisions to make concerning the extent to which we wish to tie the concept of knowledge transmission to the topic of testimony and concerning how to characterize the various non-testimonial ways in which knowledge gets around within epistemic communities.
