ABSTRACTEmotional events tend to be remembered better than neutral events, but emotional states and stimuli may also interfere with cognitive processes that underlie memory performance. The current study investigated the effects of emotional content on working memory capacity, which involves both short term storage and executive attention control. We tested competing hypotheses in a preregistered experiment. The emotional enhancement hypothesis predicts that emotional stimuli attract attention and additional processing resources relative to neutral stimuli, thereby making it easier to encode and (...) store emotional information in WMC. The emotional impairment hypothesis, by contrast, predicts that emotional stimuli interfere with attention control and the active maintenance of information in working memory. Participants completed a common measure of WMC (the operation span task; Turner, M. L., & Engle, R. W. [1989]. Is working memory capacity task dependent? Journal of Memory and Language, 28,...

The opportunity cost model offers an ultimate explanation of ego depletion that helps to move the field beyond biologically improbable resource accounts. The model's more proximate explanation, however, falls short of accounting for much data and is based on an outdated view of human rationality. We suggest that our own process model offers a better proximate account of self-control fatigue.

Birds are not commonly admired for emotional expression, and when they are, the focus is typically on negative states; yet vocal behavior is considered a direct reflection of an individual’s emotional state. Given that over 4000 species of songbird produce learned, complex, context-specific vocalizations, we make the case that songbirds are conspicuously broadcasting distinct positive emotional states and that hearing songs can also induce positive states in other birds. Studies are reviewed that demonstrate that that the production of sexually motivated (...) song reflects an emotional state of anticipatory reward-seeking (i.e., mate-seeking), while outside the mating context song in gregarious flocks reflects a state of intrinsic reward. Studies are also reviewed that demonstrate that hearing song induces states of positive anticipation and reward. This review brings together numerous studies that highlight a potentially important role for the songbird nucleus accumbens, a region nearly synonymous with reward in mammals, in positive emotional states that underlie singing behavior and responses to song. It is proposed that the nucleus accumbens is part of an evolutionarily conserved circuitry that contributes context-dependently to positive emotional states that motivate and reward singing behavior and responses to song. Neural mechanisms that underlie basic emotions appear to be conserved and similar across vertebrates. Thus, these findings in songbirds have the potential to provide insights into interventions that can restore positive social interactions disrupted by mental health disorders in humans. (shrink)

Throughout history, anthropologists have confronted a number of uncomfortable truths around the supposed nature of reality. The anthropological maxim, "through the study of others we learn more about ourselves" has been sorely tested en route. Arguably, this challenge reached culmination during the 1970s and 80s, with several prominent social commentators from Geertz to Clifford suggesting that anthropologists had, in both past and present, been much more concerned with the study of 'others' than of 'ourselves'. In essence, this reflexive critique suggested (...) that ethnographers were in the business of writing fiction and more insidiously came to the field equipped with a set of assumptions and presuppositions about the world in all its variety. These universal verities functioned to reduce all subjects of study into conformity with the observer's sense of what was real and of import and what was not and inconsequential. (shrink)

Histone variant exchange is a novel epigenetic regulator of cognition. We speculate that H2A.Z, a variant of canonical histone H2A, exerts unique effects on transcription during distinct stages of memory formation, ultimately acting to maintain memory of previous transcriptional states and poise genes for re‐activation. Hippocampus‐dependent memory formation is initiated by transient expression of memory‐related genes, which support the storage of recently acquired memories. Soon after, memories undergo systems consolidation, which transfers memories from the hippocampus to the cortex for long‐term (...) storage, and requires ongoing re‐activation of memory‐related genes. We speculate that learning‐induced H2A.Z eviction from nucleosomes initially contributes to stimulus‐induced transcriptional induction needed for the initial process of memory consolidation. During systems consolidation, we speculate that delayed incorporation of H2A.Z into nucleosomes of memory‐related genes in the cortex is needed to poise genes for rapid re‐activation, thus supporting the long‐term process of memory stabilization.Also watch the Video Abstract.

This book is an exploration of human understanding, from the perspectives of psychology, philosophy, biology and theology. The six contributors are among the most internationally eminent in their fields. Though scholarly, the writing is non-technical. No background in psychology, philosophy or theology is presumed. No other interdisciplinary work has undertaken to explore the nature of human understanding. This book is unique, and highly significant for anyone interested in or concerned about the human condition.

This article presents a fundamental advance in the theory of mental models as an explanation of reasoning about facts, possibilities, and probabilities. It postulates that the meanings of compound assertions, such as conditionals (if) and disjunctions (or), unlike those in logic, refer to conjunctions of epistemic possibilities that hold in default of information to the contrary. Various factors such as general knowledge can modulate these interpretations. New information can always override sentential inferences; that is, reasoning in daily life is defeasible (...) (or nonmonotonic). The theory is a dual process one: It distinguishes between intuitive inferences (based on system 1) and deliberative inferences (based on system 2). The article describes a computer implementation of the theory, including its two systems of reasoning, and it shows how the program simulates crucial predictions that evidence corroborates. It concludes with a discussion of how the theory contrasts with those based on logic or on probabilities. (shrink)

Review of extant research on the corporate environmental performance (CEP) and corporate financial performance (CFP) link generally demonstrates a positive relationship. However, some arguments and empirical results have demonstrated otherwise. As a result, researchers have called for a contingency approach to this research stream, which moves beyond the basic question “does it pay to be green?” and instead asks “when does it pay to be green?” In answering this call, we provide a meta-analytic review of CEP–CFP literature in which we (...) identify potential moderators to the CEP–CFP relationship including environmental performance type (e.g., reactive vs. proactive performance), firm characteristics (e.g., large vs. small firms), and methodological issues (e.g., self-report measures). By analyzing these contingencies, this study attempts to provide a basis on which to draw conclusions regarding some inconsistencies and debates in the CEP–CFP research. Some of the results of the moderator analysis suggest that small firms benefit from environmental performance as much or more than large firms, US firms seem to benefit more than international counterparts, and environmental performance seems to have the strongest influence on market-measures of financial performance.

We argue that the pratyabhijñā system of Kaśmir Śaivism holds an inconsistent position. On the one hand, the Pratyabhijñā regards Śiva as an impersonal mechanism and the universe, including persons, as not having agency; call this the Impersonal Component. On the other hand, it considers Śiva himself as a person, and individual persons as having agency sufficient to respond to Śiva; call this the Personal Component. We maintain that the Personal Component should be affirmed and the Impersonal Component rejected. The (...) Impersonal Component’s claim that Śiva is unaware of and unaffected by his manifestation should be rejected, and the doctrine of satkāryavāda should be modified. The universe is Śiva’s manifestation, in the first instance, but it also has a relative autonomy from him. Moreover, humans have agency and freedom. Their actions effect Śiva. He grows and develops in response to his manifestation. (shrink)

Two experiments investigated inferences based on suppositions. In Experiment 1, the subjects decided whether suppositions about individuals' veracity were consistent with their assertions—for example, whether the supposition “Ann is telling the truth and Beth is telling a lie”, is consistent with the premises: “Ann asserts: I am telling the truth and Beth is telling the truth. Beth asserts: Ann is telling the truth”. It showed that these inferences are more difficult than ones based on factual premises: “Ann asserts: I live (...) in Dublin and Beth lives in Dublin”. There was no difference between problems about truthtellers and liars, who always told the truth or always lied, and normals, who sometimes told the truth and sometimes lied. In Experiment 2, the subjects made inferences about factual matters set in three contexts: a truth-inducing context in which friends confided their personality characteristics, a lie-inducing context in which business rivals advertised their products, and a neutral context in which computers printed their program characteristics. Given the supposition that the individuals were lying, it was more difficult to make inferences in a truth-inducing context than in the other two contexts. We discuss the implications of our results for everyday reasoning from suppositions, and for theories of reasoning based on models or inference rules. (shrink)

This article investigates the moderating effects of organizational social consciousness on the natural environmental competency and innovativeness relationship. Organizational social consciousness reflects the organization’s awareness of its place and contribution to the larger system in which it exists and is developed through an organization’s social responsibility, ethics, culture, corporate values, and the view of its stakeholders. Through our study of key strategic decision makers from organizations located in the USA, we operationalize organizational social consciousness and demonstrate the efficacy of this (...) construct in relation to the organizational-level constructs of environmental management competency and innovativeness. Our results reveal that organizational social consciousness positively strengthens the natural environmental competency to organizational innovativeness relationship. (shrink)

Incomplete Archaeologies takes a familiar archaeological concept--assemblages--and reconsiders such groupings, collections and sets of things from the perspective of the work required to assemble them. The discussions presented here engage with the practices of collection, construction, performance and creation in the past (and present) which constitute the things and groups of things studied by archaeologists--and examine as well how these things and thing-groups are dismantled, rearranged, and even destroyed, only to be rebuilt and recreated. The ultimate aim is to reassert (...) an awareness of the incompleteness of assemblage, and thus the importance of practices of assembling (whether they seem at first creative or destructive) for understanding social life in the past as well as the present. The individual chapters represent critical engagements with this aim by archaeologists presenting a broad scope of case studies from Eurasia and the Mediterranean. Case studies include discussions of mortuary practice from numerous angles, the sociopolitics of metallurgy, human-animal relationships, landscape and memory, the assembly of political subjectivity and the curation of sovereignty. These studies emphasise the incomplete and ongoing nature of social action in the past, and stress the critical significance of a deeper understanding of formation processes as well as contextual archaeologies to practices of archaeology, museology, art history, and other related disciplines. Contributors challenge archaeologists and others to think past the objects in the assemblage to the practices of assembling, enabling us to consider not only plural modes of interacting with and perceiving things, spaces, human bodies and temporalities in the past, but also to perhaps discover alternate modes of framing these interactions and relationships in our analyses. Ultimately then, Incomplete Archaeologies takes aim at the perceived totality not only of assemblages of artefacts on shelves and desks, but also that of some of archaeology's seeming-seamless epistemological objects"--From publisher's website.

Summary In his book Serpentum et Draconum Historiae Libri Duo, the sixteenth-century Italian naturalist Ulisse Aldrovandi described and illustrated an alleged dragon that had supposedly been killed in 1572. The ?dragon? became famous and was the centrepiece of Aldrovandi's museum. The specimen, a long-necked, long-tailed, scale-covered biped with a thickened torso and a forked tongue, was unlike any currently known bipedal animal and is therefore suspicious. Even so, an explicit description of its true nature has not been published before now. (...) Here we examine Aldrovandi's description and illustration, compare these with extant animals, and conclude that the specimen was a taxidermic hoax. It was made by attaching the forelimbs of a common toad (Bufo bufo) to a European grass snake (Natrix natrix) the midsection of which had been replaced by that of a fish. Fake dragons abounded in the museums of Renaissance Europe, but only in a few cases has the mystery of their true nature been investigated. Aldrovandi's dragon can now be added to the list of such solved zoological mysteries. (shrink)

Previous research has found that more embodied insults are identified faster and more accurately than less embodied insults. The linguistic processing of embodied compliments has not been well explored. In the present study, participants completed two tasks where they identified insults and compliments, respectively. Half of the stimuli were more embodied than the other half. We examined the late positive potential component of event-related potentials in early, middle, and late time windows. Increased embodiment resulted in improved response accuracy to compliments (...) in both tasks, whereas it only improved accuracy for insults in the compliment detection task. More embodied stimuli elicited a larger LPP than less embodied stimuli in the early time window. Insults generated a larger LPP in the late time window in the insult task; compliments generated a larger LPP in the early window in the compliment task. These results indicate that electrophysiological correlates of emotional language perception are sensitive to both top-down and bottom-up processes. (shrink)

Business Ethics: A European Review, EarlyView.

Dissociative experiences have been associated with diachronic disunity. Yet, this work is in its infancy. Dissociative identity disorder is characterized by different identity states reporting their own relatively continuous sense of self. The degree to which patients in dissociative identity states experience diachronic unity has not been empirically explored. This study examined the degree to which patients in dissociative identity states experienced diachronic unity. Participants were DID adults assessed in adult and child identity states, adults with a psychotic illness, adults (...) from the general population, children from the general population and adults imagining themselves as children. They completed the Diachronic Disunity Scale, the Dissociative Experiences Scale, and the Self-Concept Clarity Scale. Diachronic disunity was not limited to psychiatric groups, but evident to some degree in all adult and child samples. The DID adult sample experienced more dissociation and self-confusion than the psychosis and adult comparison groups, but did not differ on the diachronic measure. DID patients in their child identity states and child comparisons showed disunity and were significantly different from child simulators, who showed relatively more unity. Results suggest that DID patients in either adult or child dissociative identity states, like those in other samples, do not universally experience themselves as having a consistent sense of self over time.
