  • Married Too Young? the Behavioral Ecology of 'Child Marriage'
    social sciences $€ £ ¥ Review Married Too Young? The Behavioral Ecology of ‘Child Marriage’ Susan B. Schaffnit 1,* and David W. Lawson 2 1 Department of Anthropology, Pennsylvania State University, University Park, PA 16801, USA 2 Department of Anthropology, University of California, Santa Barbara, CA 93106, USA; [email protected] * Correspondence: [email protected] Abstract: For girls and women, marriage under 18 years is commonplace in many low-income nations today and was culturally widespread historically. Global health campaigns refer to marriage below this threshold as ‘child marriage’ and increasingly aim for its universal eradication, citing its apparent negative wellbeing consequences. Here, we outline and evaluate four alternative hypotheses for the persistence of early marriage, despite its associations with poor wellbeing, arising from the theoretical framework of human behavioral ecology. First, early marriage may be adaptive (e.g., it maximizes reproductive success), even if detrimental to wellbeing, when life expectancy is short. Second, parent– offspring conflict may explain early marriage, with parents profiting economically at the expense of their daughter’s best interests. Third, early marriage may be explained by intergenerational conflict, whereby girls marry young to emancipate themselves from continued labor within natal households. Finally, both daughters and parents from relatively disadvantaged backgrounds favor early marriage as a ‘best of a bad job strategy’ when it represents the best option given a lack of feasible alternatives. The explanatory power of each hypothesis is context-dependent, highlighting the complex drivers of life history transitions and reinforcing the need for context-specific policies Citation: Schaffnit, Susan B., and addressing the vulnerabilities of adolescence worldwide.

  • THE DESCENT of MADNESS: Evolutionary Origins of Psychosis
    THE DESCENT OF MADNESS Drawing on evidence from across the behavioural and natural sciences, this book advances a radical new hypothesis: that madness exists as a costly consequence of the evolution of a sophisticated social brain in Homo sapiens. Having explained the rationale for an evolutionary approach to psych- osis, the author makes a case for psychotic illness in our living ape relatives, as well as in human ancestors. He then reviews existing evolutionary theor- ies of psychosis, before introducing his own thesis: that the same genes causing madness are responsible for the evolution of our highly social brain. Jonathan Burns’ novel Darwinian analysis of the importance of psychosis for human survival provides some meaning for this form of suffering. It also spurs us on to a renewed commitment to changing our societies in a way that allows the mentally ill the opportunity of living. The Descent of Madness will be of interest to those in the fields of psychiatry, psychology, sociology and anthropology, and is also accessible to the general reader. Jonathan Burns is chief specialist psychiatrist at the Nelson Mandela School of Medicine. His main areas of research include psychotic illnesses, human brain evolution and evolutionary origins of psychosis.

Abstract: We used computer-based automatic expression analysis to investigate the impact of im- itation on facial emotion recognition with a baseline-intervention-retest design. The participants: 55 young adults with varying degrees of autistic traits, completed an emotion recognition task with images of faces displaying one of six basic emotional expressions. This task was then repeated with instructions to imitate the expressions. During the experiment, a camera captured the participants’ faces for an automatic evaluation of their imitation performance. The instruction to imitate enhanced imitation performance as well as emotion recognition. Of relevance, emotion recognition improve- ments in the imitation block were larger in people with higher levels of autistic traits, whereas imitation enhancements were independent of autistic traits.

  • Reasoning Versus Text Processing in the Wason Selection Task: a Nondeontic Perspective on Perspective Effects
    Memory & Cognition 2000,28 (6), 1060-1070 Reasoning versus text processing in the Wason selection task: A nondeontic perspective on perspective effects AMITALMOR University ofSouthern California, Los Angeles, California and STEVEN A. SLOMAN Brown University, Providence, Rhode Island Weargue that perspective effects in the Wason four-card selection task are a product of the linguis­ tic interpretation of the rule in the context of the problem text and not of the reasoning process un­ derlying card selection. In three experiments, participants recalled the rule they used in either a se­ lection or a plausibility rating task. The results showed that (1) participants tended to recall rules compatible with their card selection and not with the rule as stated in the problem and (2) recall was not affected by whether or not participants performed card selection. Weconclude that perspective ef­ fects in the Wason selection task do not concern how card selection is reasoned about but instead re­ flect the inferential text processing involved in the comprehension of the problem text. Together with earlier research that showed selection performance in nondeontic contexts to be indistinguishable from selection performance in deontic contexts (Almor & Sloman, 1996; Sperber, Cara, & Girotto, 1995), the present results undermine the claim that reasoning in a deontic context elicits specialized cognitive processes.

  • Conditional Reasoning: the Importance of Individual Differences*
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Repositorio Institucional da Universidade de Santiago de Compostela CONDITIONAL REASONING: THE IMPORTANCE OF INDIVIDUAL DIFFERENCES* Mª Dolores Valiña, Gloria Seoane, Mª José Ferraces & Montserrat Martín University of Santiago de Compostela (Spain) INTRODUCTION The study of thinking and reasoning is a topic of central interest for economists, anthropologists, logicians, pedagogues and of course for psychologists. A central problem in the experimental investigation in Psychology is to describe how people think and reason deductively and inductively. There are three fundamental theoretical approaches to deductive reasoning in the Cognitive Psychology: mental logic, mental models and pragmatic schemas (see Evans, Newstead & Byrne, 1993, for a detailed review). There are several proponents of a universal mental logic (Inhelder & Piaget, 1958) or natural logics (Braine, 1978, 1990, 1994; Braine & O´Brien, 1991; Braine & Rumain, 1983; Osherson, 1974, 1975; Rips, 1983, 1990, 1994). Other authors propose that reasoning is based on construction and evaluation of mental models (Johnson-Laird, 1983; Johnson-Laird & Byrne, 1991). A third approach asserts that reasoning is not based on general inference rules and assumes that people have domain-specific reasoning mechanisms such as pragmatic reasoning schemas inductively acquired (Cheng & Holyoak, 1985, 1989; Cheng, Holyoak, Nisbett & Oliver, 1986; Holyoak & Cheng, 1995) or innates procedures for identify potential deviations from social contracts (Cosmides 1985, 1989; Cosmides & Tooby, 1992) _______________________ * An extended version of this paper has been published in the chapter: “Conditional reasoning: The importance of individual differences”, of the book: Mental Models in Reasoning, J.A.

  • The Law of Placenta
    The Law of Placenta Mathilde Cohent ABSTRACT: Of the forms of reproductive labor in which legal scholars have been interested, placenta, the organ developed during pregnancy, has been overlooked. As placenta becomes an object of value for a growing number of individuals, researchers, clinicians, biobanks, and biotech companies, among others, its cultural meaning is changing. At the same time, these various constituencies may be at odds. Some postpartum parents and their families want to repossess their placenta for personal use, while third parties use placentas for a variety of research, medical, and commercial purposes. This Article contributes to the scholarship on reproductive justice and agency by asking who should have access to placentas and under what conditions. The Article emphasizes the insufficient protection the law affords pregnant people wishing to decide what happens to their placenta. Generally considered clinical waste under federal and state law, placental tissue is sometimes made inaccessible to its producers on the ground that it is infectious at the same time as it is made available to third parties on the ground that placenta is discarded and de-identified tissue. Less privileged people who lack the ability to shop for obstetric and other pregnancy-related services that allow them to keep their placentas are at a disadvantage in this chain of supply and demand. While calling for further research on the modus operandi of placenta markets and how pregnant people think about them, this Article concludes that lawmakers should take steps to protect decision-making autonomy over placental labor and offers a range of proposals to operationalize this idea.

  • Integrative Anthropology and the Human Niche: Toward a Contemporary Approach to Human Evolution
    AMERICAN ANTHROPOLOGIST Integrative Anthropology and the Human Niche: Toward a Contemporary Approach to Human Evolution Agustın´ Fuentes ABSTRACT A niche is the structural, temporal, and social context in which a species exists. Over the last two million years, the human lineage underwent clear morphological changes alongside less easily measurable, but significant, behavioral and cognitive shifts as it forged, and was shaped by, new niches. During this time period, core human patterns emerged, including the following: hypercooperation; lengthy childhood and complex parenting; intricate and diverse foraging and hunting patterns; novel and dynamic material and symbolic cultures; and complex communication and information sharing, eventually resulting in language. Approaches to human evolution grounded in paleoanthropology and archaeology offer fundamental insights into our past, and traditional evolutionary the- ory offers a strong grounding for explaining them. However, given the centrality of distinctive physiological, social, semiotic, and cognitive processes in human evolutionary histories, a broader anthropological approach can facilitate additional understanding of the human story. An integrative anthropology, reaching across subfields and foci, com- bined with contemporary evolutionary theory is an approach that can enhance our abilities to model and understand human evolution.
