Social learning has been shown to be an evolutionarily adaptive strategy, but it can be implemented via many different cognitive mechanisms. The adaptive advantage of social learning depends crucially on the ability of each learner to obtain relevant and accurate information from informants. The source of informants’ knowledge is a particularly important cue for evaluating advice from multiple informants; if the informants share the source of their information or have obtained their information from each other, then their testimony is statistically (...) dependent and may be less reliable than testimony from informants who do not share information. In this study, we use a Bayesian model to determine how rational learners should incorporate the effects of shared information when learning from other people, conducting three experiments that examine whether human learners behave similarly. We find that people are sensitive to a number of different patterns of dependency, supporting the use of a sophisticated strategy for social learning that goes beyond copying the majority, and broadening the situations in which social learning is likely to be an adaptive strategy.

The aim of this review is to show the fruitfulness of using images of facial expressions as experimental stimuli in order to study how neural systems support biologically relevant learning as it relates to social interactions. Here we consider facial expressions as naturally conditioned stimuli which, when presented in experimental paradigms, evoke activation in amygdala–prefrontal neural circuits that serve to decipher the predictive meaning of the expressions. Facial expressions offer a relatively innocuous strategy with which to investigate these normal variations (...) in affective information processing, as well as the promise of elucidating what role the aberrance of such processing might play in emotional disorders.

Lists of species underpin many fields of human endeavour, but there are currently no universally accepted principles for deciding which biological species should be accepted when there are alternative taxonomic treatments (and, by extension, which scientific names should be applied to those species). As improvements in information technology make it easier to communicate, access, and aggregate biodiversity information, there is a need for a framework that helps taxonomists and the users of taxonomy decide which taxa and names should be used (...) by society whilst continuing to encourage taxonomic research that leads to new species discoveries, new knowledge of species relationships, and the refinement of existing species concepts. Here, we present 10 principles that can underpin such a governance framework, namely (i) the species list must be based on science and free from nontaxonomic considerations and interference, (ii) governance of the species list must aim for community support and use, (iii) all decisions about list composition must be transparent, (iv) the governance of validated lists of species is separate from the governance of the names of taxa, (v) governance of lists of accepted species must not constrain academic freedom, (vi) the set of criteria considered sufficient to recognise species boundaries may appropriately vary between different taxonomic groups but should be consistent when possible, (vii) a global list must balance conflicting needs for currency and stability by having archived versions, (viii) contributors need appropriate recognition, (ix) list content should be traceable, and (x) a global listing process needs both to encompass global diversity and to accommodate local knowledge of that diversity. We conclude by outlining issues that must be resolved if such a system of taxonomic list governance and a unified list of accepted scientific names generated are to be universally adopted. (shrink)

In this article, I examine two competing republican ideals of a free society of equals in the eighteenth century. I claim that while the value of nondependency was central to the economic outlooks of both Adam Smith and Richard Price, their evaluations of free-market practices were dramatically distinct. In doing so, I introduce a new interpretation of the typologies of republicanism in the eighteenth century.

The modernization of Burgundy during the late nineteenth and early twentieth centuries drew on the coordinated efforts of numerous industrial and cultural sectors. Among these innovative developments, new tourism industries played a prominent role in providing new opportunities for the consumption of local products while redefining existing conceptions of Burgundian landscapes. This entailed collaboration of a variety of cultural intermediaries ranging from local boosters to politicians and from merchants to academics. Geographers contributed by incorporating symbolic, subjective, and performative practices into (...) the existing regional concepts of terroir and genres-de-vie. The result was newly scripted roles for tourists and locals to participate in gastronomic activities that, by virtue of the experience, altered participants’ experience of time, space, and themselves. Rapidly institutionalized in Burgundy, these developments illustrate how contemporary commercial interests influenced geographic notions of place in the French provinces. (shrink)

Communicative Understandings of Women's Leadership Development: From Ceilings of Glass to Labyrinth Paths, edited by Elesha L. Ruminski and Annette M. Holba, weaves the disciplines of communication studies, leadership studies, and women's studies to offer theoretical and practical reflection about women's leadership development in academic, organizational, and political contexts. This work claims a space for women's leadership studies and acknowledges the paradigmatic shift from discussing women's leadership using the glass ceiling to what Eagly and Carli identify as the labyrinth of (...) leadership.

Multimodal integration is the formation of a coherent percept from different sensory inputs such as vision, audition, and somatosensation. Most research on multimodal integration in speech perception has focused on audio-visual integration. In recent years, audio-tactile integration has also been investigated, and it has been established that puffs of air applied to the skin and timed with listening tasks shift the perception of voicing by naive listeners. The current study has replicated and extended these findings by testing the effect of (...) air puffs on gradations of voice onset time along a continuum rather than the voiced and voiceless endpoints of the original work. Three continua were tested: bilabial (“pa/ba”), velar (“ka/ga”), and a vowel continuum (“head/hid”) used as a control. The presence of air puffs was found to significantly increase the likelihood of choosing voiceless responses for the two VOT continua but had no effect on choices for the vowel continuum. Analysis of response times revealed that the presence of air puffs lengthened responses for intermediate (ambiguous) stimuli and shortened them for endpoint (non-ambiguous) stimuli. The slowest response times were observed for the intermediate steps for all three continua, but for the bilabial continuum this effect interacted with the presence of air puffs: responses were slower in the presence of air puffs, and faster in their absence. This suggests that during integration auditory and aero-tactile inputs are weighted differently by the perceptual system, with the latter exerting greater influence in those cases where the auditory cues for voicing are ambiguous.

Presenting traditional views alongside new critical approaches, the chapters in this book present fresh perspectives on the poetics of the 12th-century author, Marie de France, the first woman of letters to write in French.

Although Norris, McQueen & Cutler have provided convincing evidence that there is no need for contributions from the lexicon to phonetic processing, their simplification of the communication between levels comes at a cost to the processes themselves. Although their arrangement may ultimately prove correct, its validity is not due to a successful application of Occam's razor.

The managerial ethics literature is used as a base for the inclusion of Ethical Attribution, as an element in the consumer's decision process. A situational model of ethical consideration in consumer behavior is proposed and examined for Personal vs. Vicarious effects. Using a path analytic approach, unique structures are reported for Personal and Vicarious situations in the evaluation of a seller's unethical behavior. An attributional paradigm is suggested to explain the results.
