Filmmakers use continuity editing to engender a sense of situational continuity or discontinuity at editing boundaries. The goal of this study was to assess the impact of continuity editing on how people perceive the structure of events in a narrative film and to identify brain networks that are associated with the processing of different types of continuity editing boundaries. Participants viewed a commercially produced film and segmented it into meaningful events, while brain activity was recorded with functional magnetic resonance imaging (...) (MRI). We identified three degrees of continuity that can occur at editing locations: edits that are continuous in space, time, and action; edits that are discontinuous in space or time but continuous in action; and edits that are discontinuous in action as well as space or time. Discontinuities in action had the biggest impact on behavioral event segmentation, and discontinuities in space and time had minor effects. Edits were associated with large transient increases in early visual areas. Spatial-temporal changes and action changes produced strikingly different patterns of transient change, and they provided evidence that specialized mechanisms in higher order perceptual processing regions are engaged to maintain continuity of action in the face of spatiotemporal discontinuities. These results suggest that commercial film editing is shaped to support the comprehension of meaningful events that bridge breaks in low-level visual continuity, and even breaks in continuity of spatial and temporal location.

What role do moment‐to‐moment comprehension processes play in visual attentional selection in picture stories? The current work uniquely tested the role of bridging inference generation processes on eye movements while participants viewed picture stories. Specific components of the Scene Perception and Event Comprehension Theory (SPECT) were tested. Bridging inference generation was induced by manipulating the presence of highly inferable actions embedded in picture stories. When inferable actions are missing, participants have increased viewing times for the immediately following critical image ( (...) class='Hi'>Magliano, Larson, Higgs, & Loschky, ). This study used eye‐tracking to test competing hypotheses about the increased viewing time: (a) Computational Load: inference generation processes increase overall computational load, producing longer fixation durations; (b) Visual Search: inference generation processes guide eye‐movements to pick up inference‐relevant information, producing more fixations. Participants had similar fixation durations, but they made more fixations while generating inferences, with that process starting from the fifth fixation. A follow‐up hypothesis predicted that when generating inferences, participants fixate scene regions important for generating the inference. A separate group of participants rated the inferential‐relevance of regions in the critical images, and results showed that these inferentially relevant regions predicted differences in other viewers’ eye movements. Thus, viewers’ event models in working memory affect visual attentional selection while viewing visual narratives. (shrink)

Drawn sequences of images, like those in comics and picture stories, are a pervasive and fundamental way that humans have communicated for millennia. Yet, the study of visual narratives has only recently gained traction in Cognitive Science. Here we explore what has held back the study of the cognition of visual narratives, and why researchers should join in scholarship of this ubiquitous aspect of expression.

The goal of this study was to assess the relationships between computational approaches to analyzing constructed responses made during reading and individual differences in the foundational skills of reading in college readers. We also explored if these relationships were consistent across texts and samples collected at different institutions and texts. The study made use of archival data that involved college participants who produced typed constructed responses under thinking aloud instructions reading history and science texts. They also took assessments of vocabulary (...) knowledge and proficiency in comprehension. The protocols were analyzed to assess two different ways to determine their cohesion. One approach involved assessing how readers established connections with themselves. The other approach involved assessing connections between the constructed responses and the texts that were read. Additionally, the comparisons were made by assessing both lexical and semantic comparisons. The result showed that both approaches for analyzing cohesion and making the comparisons were correlated with vocabulary knowledge and comprehension proficiency. The implications of the results for theory and practice are discussed. (shrink)

Understanding how people comprehend visual narratives (including picture stories, comics, and film) requires the combination of traditionally separate theories that span the initial sensory and perceptual processing of complex visual scenes, the perception of events over time, and comprehension of narratives. Existing piecemeal approaches fail to capture the interplay between these levels of processing. Here, we propose the Scene Perception & Event Comprehension Theory (SPECT), as applied to visual narratives, which distinguishes between front-end and back-end cognitive processes. Front-end processes occur (...) during single eye fixations and are comprised of attentional selection and information extraction. Back-end processes occur across multiple fixations and support the construction of event models, which reflect understanding of what is happening now in a narrative (stored in working memory) and over the course of the entire narrative (stored in long-term episodic memory). We describe relationships between front- and back-end processes, and medium-specific differences that likely produce variation in front-end and back-end processes across media (e.g., picture stories vs. film). We describe several novel research questions derived from SPECT that we have explored. By addressing these questions, we provide greater insight into how attention, information extraction, and event model processes are dynamically coordinated to perceive and understand complex naturalistic visual events in narratives and the real world.

Approaches to clinical ethics dilemmas that rely on basic principles or rules are difficult to apply because of vagueness and conflict among basic values. In response, casuistry rejects the use of basic values, and specification produces a large set of specified rules that are presumably easily applicable. Balancing is a method employed to weigh the relative importance of different and conflicting values in application. We argue against casuistry and specification, claiming that balancing is superior partly because it most clearly exhibits (...) the reasoning behind moral decision-making. Hence, balancing may be most effective in teaching bioethics to medical professionals. (shrink)

Researchers designing a clinical trial may be aware of disputed evidence of serious risks from previous studies. These researchers must decide whether and how to describe these risks in their model informed consent document. They have an ethical obligation to provide fully informed consent, but does this obligation include notice of controversial evidence? With ACCORD as an example, we describe a framework and criteria that make clear the conditions requiring inclusion of important controversial risks. The ACCORD model consent document did (...) not include notice of prior trials with excess death. We develop and explain a new standard labeled risk in equipoise. We argue that our approach provides an optimal level of integrity to protect the informational needs of the reasonable volunteers who agree to participate in clinical trials. We suggest language to be used in a model consent document and the informed consent discussion when such controversial evidence exists. (shrink)

The controversy over the equivalence of continuous sedation until death (CSD) and physician-assisted suicide/euthanasia (PAS/E) provides an opportunity to focus on a significant extended use of CSD. This extension, suggested by the equivalence of PAS/E and CSD, is designed to promote additional patient autonomy at the end-of-life. Samuel LiPuma, in his article, “Continuous Sedation Until Death as Physician-Assisted Suicide/Euthanasia: A Conceptual Analysis” claims equivalence between CSD and death; his paper is seminal in the equivalency debate. Critics contend that sedation follows (...) proportionality protocols for which LiPuma’s thesis does not adequately account. Furthermore, sedation may not eliminate consciousness, and as such LiPuma’s contention that CSD is equivalent to neocortical death is suspect. We not only defend the equivalence thesis, but also expand it to include additional moral considerations. First, we explain the equivalence thesis. This is followed by a defense of the thesis against five criticisms. The third section critiques the current use of CSD. Finally, we offer two proposals that, if adopted, would broaden the use of PAS/E and CSD and thereby expand options at the end-of-life. (shrink)

Neil Levy offers the most prominent moral principles that are specifically and exclusively designed to apply to neuroethics. His two closely related principles, labeled as versions of the ethical parity principle , are intended to resolve moral concerns about neurological modification and enhancement [1]. Though EPP is appealing and potentially illuminating, we reject the first version and substantially modify the second. Since his first principle, called EPP , is dependent on the contention that the mind literally extends into external props (...) such as paper notebooks and electronic devices, we begin with an examination of the extended mind hypothesis and its use in Levy’s EPP . We argue against reliance on EMH as support for EPP . We turn to his second principle, EPP , which is not dependent on EMH but is tied to the acceptable claim that the mind is embedded in, because dependent on, external props. As a result of our critique of EPP , we develop a modified version of EPP , which we argue is more acceptable than Levy’s principle. Finally, we evaluate the applicability of our version of EPP.

As currently practiced, the use of continuous sedation until death (CSD) is controlled by clinicians in a way that may deny patients a key choice in controlling their dying process. Ethical guidelines from the American Medical Association and the American Academy of Pain Medicine describe CSD as a “last resort,” and a position statement from the American Academy of Hospice and Palliative Medicine describe it as “an intervention reserved for extreme situations.” Accordingly, patients must progress to unremitting pain and suffering (...) and reach a last-resort stage before the option to pursue CSD is considered. Alternatively, we present and defend a new guideline in which decisionally capable, terminally ill patients who have a life expectancy of less than six months may request CSD before being subjected to the refractory suffering of a treatment of “last resort.”.

Some bioethicists have argued in favor of a sliding scale notion of competence, paternalistically requiring greater competence in relation to more significant risk. I argue against a sliding scale notion, taking issue with the positions of Allen E. Buchanan and Dan W. Brock, Ian Wilkes, and Joel Feinberg. Rejecting arguments that a sliding scale is supported by legal cases, by ordinary usage, and by fallible judgments about competence, I argue in favor of greater evidence of competence when risk is greater. (...) Two clinical cases are examined, both involving amputation, to show that my fixed concept of competence, with a requirement of clearer evidence of competence when risk is high, better accounts for good moral decisions in bioethics.

Susan D. McCammon and Nicole M. Piemonte offer a thoughtful and thorough commentary on our manuscript entitled “Expanding the use of Continuous Sedation Until Death.” In this reply we attempt to clarify and further defend our position. We show how continuous sedation until death is not a “first resort” but rather a legitimate option among many that should available to terminally ill patients whose life expectancy is less than six months. We also attempt to show that we do not equivocate (...) the meaning of palliative care as the commentators suggested. We argue that the traditional notion of palliative care should move beyond relief of “experienced suffering” to relief of potential suffering for those whose life expectancy is less than six months. Lastly, we challenge the commentator’s position that the realm of ordinary medicine” should be the guide to care, by showing how the notion of ordinary medicine has been successfully challenged in both bioethical scholarship and the courts in a way that shows ordinary medicine to be an evolving concept rather than a static, universal guide.

People often choose intuitive rather than equally valid nonintuitive alternatives. The authors suggest that these intuitive biases arise because intuitions often spring to mind with subjective ease, and the subjective ease leads people to hold their intuitions with high confidence. An investigation of predictions against point spreads found that people predicted intuitive options more often than equally valid nonintuitive alternatives. Critically, though, this effect was largely determined by people's confidence in their intuitions. Across naturalistic, expert, and laboratory samples, against personally (...) determined point spreads, and even when intuitive confidence was manipulated by altering irrelevant aspects of the decision context, the authors found that decreasing intuitive confidence reduced or eliminated intuitive biases. These findings indicate that intuitive biases are not inevitable but rather predictably determined by contextual variables that affect intuitive confidence. (shrink)

In order for a moral theory to support application it must be able to provide determinate answers to actual moral problems or, at the least, to significantly narrow acceptable options. It must also support the development of a genuine consensus, one that is disinterested, reasonable, and unbiased. I argue that theories concentrating on principles, or on rules, or on particular cases fail to meet these standards. A full coherence theory, taking into account principles, rules, practices, and judgments holds the greatest (...) promise for successful application. I present a detailed outline of a full coherence theory that is principled, pluralistic, and comprehensive. This coherence theory includes three basic principles (expressed both negatively and positively), but binds these, in terms of their explication and application, to rules and practices. This theory respects current practices but also directs us to change practices and institutions and even the interpretation of basic moral principles. The theory includes ways to determine which aspect of moral experience should take precedence in given circumstances, ways to determine who has particular obligations, and how — by means of a mutuality principle — value may be enhanced under conditions of value conflict.
