Oaksford & Chater's (O&C's) account of deductive reasoning is parsimonious at a local level (because a rational model is used to explain a wide range of behavior) and at a global level (because their Bayesian approach connects to other areas of research). Their emphasis on environmental structure is especially important, and the power of their approach is seen at both the computational and algorithmic levels.

For a variety of reasons, including the common use of deception in psychology experiments, participants often disbelieve experimenters' assertions about important task parameters. This can lead researchers to conclude incorrectly that participants are behaving non- normatively. The problem can be overcome by deriving and testing normative models that do not assume full belief in key task parameters. A real experimental example is discussed.

Any instance (i.e., event, behavior, trait) belongs to infinitely many reference classes, hence there are infinitely many base rates from which to choose. People clearly do not entertain all possible reference classes, however, so something must be limiting the search space. We suggest some possible mechanisms that determine which reference class is evoked for the purpose of judgment and decision.

The normative principle of description invariance presupposes that rational preferences must be complete. The completeness axiom is normatively dubious, however, and its rejection opens the door to rational framing effects. In this commentary, we suggest that Bermúdez's insightful challenge to the standard normative view of framing can be clarified and extended by situating it within a broader critique of completeness.

Psychologists and philosophers who pose moral dilemmas to understand moral judgment typically specify outcomes as certain to occur in them. This contrasts with real-life moral decision-making, which is almost always infused with probabilities (e.g., the probability of a given outcome if an action is or is not taken). Seven studies examine sensitivity to the size and location of shifts in probabilities of outcomes that would result from action in moral dilemmas. We find that moral judgments differ between actions that result (...) in an equal increase in probability of harm (equal size), but have different end-states (e.g., an increase in harm probability from 25% to 50% or from 50% to 75%). This deviation from expected value is robust under separate evaluation, and increases when the comparison between shifts is made explicit under simultaneous evaluation. Consistent with the centrality of perceived harm in some models of moral judgment, perceived harm partially mediates sensitivity to location of harm probability shift. Unlike for shifts in harm probabilities, participants are insensitive to the location of shifts in probability of beneficial outcomes. They are also insensitive to the location of shifts in probability of analogous monetary losses and gains, suggesting an asymmetry between harm and benefit in moral reasoning, as well as an asymmetry between moral and monetary decision-making more broadly. Implications for normative philosophical theory and moral psychological theory, as well as practical applications, are discussed. (shrink)

The mammalian chromosome is longitudinally heterogeneous in structure and function and this is the basis for the specific banding patterns produced by various chromosome staining techniques. The two most frequently used techniques are G, or Giemsa banding and R, or reverse banding. Each type of stained band is characterised by variations in gene density, time of replication, base composition, density of repeat sequences, and chromatin packaging. It is increasingly apparent that R and G bands, which are complementary to each other, (...) represent separate compartments of the euchromatic human genome, with R bands containing the vast majority of genes. R bands are also more GC‐rich, contain a higher density of Alu repeats, and replicate earlier in S phase, than G bands. These properties may be interdependent and may have coevolved. (shrink)

Whitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

This article is the lead piece in a special report that presents the results of a bioethical investigation into chimeric research, which involves the insertion of human cells into nonhuman animals and nonhuman animal embryos, including into their brains. Rapid scientific developments in this field may advance knowledge and could lead to new therapies for humans. They also reveal the conceptual, ethical, and procedural limitations of existing ethics guidance for human‐nonhuman chimeric research. Led by bioethics researchers working closely with an (...) interdisciplinary work group, the investigation focused on generating conceptual clarity and identifying improvements to governance approaches, with the goal of helping scholars, funders, scientists, institutional leaders, and oversight bodies (embryonic stem cell research oversight [ESCRO] committees and institutional animal care and use committees [IACUCs]) deliver principled and trustworthy oversight of this area of science. The article, which focuses on human‐nonhuman animal chimeric research that is stem cell based, identifies key ethical issues in and offers ten recommendations regarding the ethics and oversight of this research. Turning from bioethics’ previous focus on human‐centered questions about the ethics of “humanization” and this research's potential impact on concepts like human dignity, this article emphasizes the importance of nonhuman animal welfare concerns in chimeric research and argues for less‐siloed governance and oversight and more‐comprehensive public communication.

Rare copy number variants have a prominent role in the aetiology of schizophrenia and other neuropsychiatric disorders. Substantial risk for schizophrenia is conferred by large CNVs at several loci, including microdeletions at 1q21.1, 3q29, 15q13.3 and 22q11.2 and microduplication at 16p11.2. However, these CNVs collectively account for a small fraction of cases, and the relevant genes and neurobiological mechanisms are not well understood. Here we performed a large two-stage genome-wide scan of rare CNVs and report the significant association of copy (...) number gains at chromosome 7q36.3 with schizophrenia. Microduplications with variable breakpoints occurred within a 362-kilobase region and were detected in 29 of 8,290 patients versus 2 of 7,431 controls in the combined sample. All duplications overlapped or were located within 89 kilobases upstream of the vasoactive intestinal peptide receptor gene VIPR2. VIPR2 transcription and cyclic-AMP signalling were significantly increased in cultured lymphocytes from patients with microduplications of 7q36.3. These findings implicate altered vasoactive intestinal peptide signalling in the pathogenesis of schizophrenia and indicate the VPAC2 receptor as a potential target for the development of new antipsychotic drugs. © 2011 Macmillan Publishers Limited.

Religious and Ethical Perspectives on Global Migration examines the complicated social ethics of migration in today's world. Editors Elizabeth W. Collier and Charles R. Strain bring the perspectives of an international group of scholars toward a theory of justice and ethical understanding for the nearly two hundred million migrants who have left their homes seeking asylum from political persecution, greater freedom and safety, economic opportunity, or reunion with family members.

Craig Eisendrath reinterprets and unifies the writings of the late-nineteenth-century psychologist William James and the twentieth-century philosopher Alfred North Whitehead. James's psychology achieves greater depth by its grounding in philosophic doctrine, and Whitehead's abstract and frequently abstruse philosophy gains greater specificity through the concrete illustrations provided by a wealth of psychological evidence. The result is an extension of James and an exegesis of Whitehead. The merging of James's theory of will and Whitehead's theory of concrescence and organism is the (...) central pivot of the book. Eisendrath discusses as well the philosophical traditions behind both men and analyzes their theories on perception, time, space, causality, the nature and role of ideas, the laws of nature, God and civilization.

The general purposes of this essay are as follows: First, to outline an ecological model of autobiographical remembering by examining the purposes, processes, and products of reconstructing meaningful memories. Second, to argue that autobiographical remembering is embedded in affective, interpersonal, sociocultural, and historical contexts. Improvised selves are created in present contexts to serve psychosocial, cultural, and historical purposes, and third, to demonstrate essential constraints on the construction of coherent personal narratives that give meaning and purpose to our everyday lives. -/- (...) The specific aim of this essay is to illustrate that the subjective experiences of trauma and atrocity often lack the essential narrative elements needed to give coherence to those experiences as well as affectively grounded evaluative information. Evaluations of experiences give meaning to our lives. Evaluative information leads to culturally recognized coherent stories structured by known canonical narrative forms because affect conveys how subjective experiences should be interpreted and understood. On this view, autobiographical memories that are the essence of one's personal history can appear as coherent or incoherent to others to the extent others are familiar with the narrative structure used to reconstruct the past and the coherence inherent in autobiographical memories associated with the temporal and evaluative structure of those recollections. -/- I claim that autobiographical experiences that cannot be reconstructed and shared through spoken or written language, music, movement (e.g., dance), art, literature, or science precipitate feelings of existential stress because articulated deep motivations cannot be related intimately to others.

A model of autobiographical remembering and the creation of personal culture is proposed. In this model we hypothesize that autobiographical memories are instantiations--objectifications as in metaphors or idioms-constituted through reconstructive processes that come to be recognized as self. Such memories are subsequently subjectified as personal culture. Our emphasis is on the functions and uses of autobiographical remembering, especially in interaction with others, where reconstructed memories are marked with affective significance. We propose that memories become autobiographical as a function of how (...) they are used--to establish and maintain intimacies or to calm ourselves during times of hightened anxiety-and signified by affect and emotion. From an object-relations theory perspective, autobiographical memories are seen as transitional phenomena (selfobjects) that reconstitue caregiving relationships both when we are alone and when we are interacting with others.
