Observers have difficulty detecting visual changes. However, they are unaware of this inability, suggesting that people do not have an accurate understanding of visual processes. We explored whether this error is related to participants’ beliefs about the roles of intention and scene complexity in detecting changes. In Experiment 1 participants had a higher failure rate for detecting changes in an incidental change detection task than an intentional change detection task. This effect of intention was greatest for complex scenes. However, participants (...) predicted equal levels of change detection for both types of changes across scene complexity. In Experiment 2, emphasizing the differences between intentional and incidental tasks allowed participants to make predictions that were less inaccurate. In Experiment 3, using more sensitive measures and accounting for individual differences did not further improve predictions. These findings suggest that adults do not fully understand the role of intention and scene complexity in change detection. (shrink)

Many experiments have demonstrated that people fail to detect seemingly large visual changes in their environment. Despite these failures, most people confidently predict that they would see changes that are actually almost impossible to see. Therefore, in at least some situations visual experience is demonstrably not what people think it is. This paper describes a line of research suggesting that overconfidence about change detection reflects a deeper metacognitive error founded on beliefs about attention and the role of meaning as a (...) support for a coherent perceptual experience. Accordingly, CBB does not occur in all situations , while the scope of the phenomenon remains broad enough to suggest more than a misunderstanding of a small niche of visual experience. I finish by arguing that despite the very small amount of research on visual metacognition, these beliefs are critical to understand. (shrink)

Smilek, Eastwood, Reynolds, and Kingstone suggests that the studies reported in Beck, M. R., Levin, D. T. and Angelone, B. A. are not ecologically valid. Here, we argue that not only are change blindness and change blindness blindness studies in general ecologically valid, but that the studies we reported in Beck, Levin, and Angelone, 2007 are as well. Specifically, we suggest that many of the changes used in our study could reasonably be expected to occur in the real (...) world. Furthermore, the conclusion from Beck et al. that knowledge about the role of intention and scene complexity in change detection is not readily accessible applies not only to the laboratory studies we conducted but also to real world situations.

Recently, a number of experiments have emphasized the degree to which subjects fail to detect large changes in visual scenes. This finding, referred to as “change blindness,” is often considered surprising because many people have the intuition that such changes should be easy to detect. Levin, Momen, Drivdahl, and Simons documented this intuition by showing that the majority of subjects believe they would notice changes that are actually very rarely detected. Thus subjects exhibit a metacognitive error we refer to (...) as “change blindness blindness.” Here, we test whether CBB is caused by a misestimation of the perceptual experience associated with visual changes and show that it persists even when the pre- and postchange views are separated by long delays. In addition, subjects overestimate their change detection ability both when the relevant changes are illustrated by still pictures, and when they are illustrated using videos showing the changes occurring in real time. We conclude that CBB is a robust phenomenon that cannot be accounted for by failure to understand the specific perceptual experience associated with a change. (shrink)

Although eye tracking has been used extensively to assess cognitions for static stimuli, recent research suggests that the link between gaze and cognition may be more tenuous for dynamic stimuli such as videos. Part of the difficulty in convincingly linking gaze with cognition is that in dynamic stimuli, gaze position is strongly influenced by exogenous cues such as object motion. However, tests of the gaze‐cognition link in dynamic stimuli have been done on only a limited range of stimuli often characterized (...) by highly organized motion. Also, analyses of cognitive contrasts between participants have been mostly been limited to categorical contrasts among small numbers of participants that may have limited the power to observe more subtle influences. We, therefore, tested for cognitive influences on gaze for screen‐captured instructional videos, the contents of which participants were tested on. Between‐participant scanpath similarity predicted between‐participant similarity in responses on test questions, but with imperfect consistency across videos. We also observed that basic gaze parameters and measures of attention to centers of interest only inconsistently predicted learning, and that correlations between gaze and centers of interest defined by other‐participant gaze and cursor movement did not predict learning. It, therefore, appears that the search for eye movement indices of cognition during dynamic naturalistic stimuli may be fruitful, but we also agree that the tyranny of dynamic stimuli is real, and that links between eye movements and cognition are highly dependent on task and stimulus properties.

Past research has repeatedly documented the close relationship between visual attention and awareness. Most recently, research exploring change blindness, inattentional blindness, repetition blindness, and the attentional blink has converged on the conclusion that attention to one aspect of a scene or event may lead to a highly circumscribed awareness of only the specific information attended, while other information, even that which is spatially or temporally nearby can go completely unnoticed. In the present report, we extend these observations to the dynamic (...) allocation of attention during a well-structured meaningful event. In two experiments, subjects viewed brief videos of simple events and were told to pay close attention to them. During the events, an unexpected disruption consisting of a brief low spatial frequency motion field occurred. Despite intensive questioning and opportunities for recognition, the majority of subjects reported no awareness of 200, 400, or 600 ms disruptions. In a second experiment, blank-screen disruptions were added, and these resulted in no increase in detection. We conclude that visual attention may result in far more transitory awareness of visual information than previously appreciated. (shrink)

Recent research exploring phenomena such as change blindness, inattentional blindness, attentional blink and repetition blindness has revealed a number of counterintuitive ways in which apparently salient visual stimuli often go unnoticed. In fact, large majorities of subjects sometimes predict that they would detect visual changes that actually are rarely noticed, suggesting that people have strong beliefs about visual experience that are demonstrably incorrect. However, for other kinds of visual metacognition, such as picture memory, people underpredict performance. This paper describes two (...) experiments demonstrating that both these overpredictions of change detection, and underpredictions of visual memory can be linked with intuitions about the visual experience of different kinds of agents. Subjects predicted more visual change detection and poorer visual memory for mechanical representational systems when these were anthropomorphized using intentional terminology. (shrink)

People may exhibit two kinds of modifications when demonstrating action for others: modifications to facilitate bottom‐up, or sensory‐based processing; and modifications to facilitate top‐down, or knowledge‐based processing. The current study examined actors' production of such modifications in action demonstrations for audiences that differed in their capacity for intentional reasoning. Actors' demonstrations of complex actions for a non‐anthropomorphic computer system and for people (adult and toddler) were compared. Evidence was found for greater highlighting of top‐down modifications in the demonstrations for the (...) human audiences versus the computer audience. Conversely, participants highlighted simple perceptual modifications for the computer audience, producing more punctuated and wider ranging motions. This study suggests that people consider differences in their audiences when demonstrating action. (shrink)

Previous research demonstrates that implicitly learned probability information can guide visual attention. We examined whether the probability of an object changing can be implicitly learned and then used to improve change detection performance. In a series of six experiments, participants completed 120–130 training change detection trials. In four of the experiments the object that changed color was the same shape on every trial. Participants were not explicitly aware of this change probability manipulation and change detection performance was not improved for (...) the trained shape versus untrained shapes. In two of the experiments, the object that changed color was always in the same general location . Although participants were not explicitly aware of the change probability, implicit knowledge of it did improve change detection performance in the trained location. These results indicate that improved change detection performance through implicitly learned change probability occurs for location but not shape. (shrink)

The contributors to The Moral of the Story, all preeminent political theorists, are unified by their concern with the instructive power of great literature. This thought-provoking combination of essays explores the polyvalent moral and political impact of classic world literatures on public ethics through the study of some of its major figures-including Shakespeare, Dante, Cervantes, Jane Austen, Henry James, Joseph Conrad, Robert Penn Warren, and Dostoevsky. Positing the uniqueness of literature's ability to promote dialogue on salient moral and intellectual virtues, (...) editor Henry T. Edmonson III has culled together a wide-ranging exploration of such fundamental concerns as the abuse of authority, the nature of good leadership, the significance of "middle class virtues" and the needs of adolescents. This collection reinvigorates the study of classic literature as an endeavor that is not only personally intellectually satisfying, but also an inimitable and unique way to enrich public discourse.

Studies of change blindness indicate that more intentional monitoring of changes is necessary to successfully detect changes as scene complexity increases. However, there have been conflicting reports as to whether people are aware of this relation between intention and successful change detection as scene complexity increases. Here we continue our dialogue with [Beck, M. R., Levin, D. T., & Angelone, B. . Change blindness blindness: Beliefs about the roles of intention and scene complexity in change detection.

We also discuss how this dialogue illustrates the need for psychological studies to be grounded in measurements taken from real world situations rather than laboratory experiments or questionnaires.

Ayahuasca, a hallucinogen with profound consciousness- altering properties, has been increasingly utilized in recent studies (e.g., Strassman, 2001; Shanon, 2002a,b). However, other than Shanon's recent work, there has been little attempt to examine the effects of ayahuasca on perceptual, affective and cognitive experience, its relation to fringe consciousness or to pertinent personality variables. Twenty-one volunteers attending a seminar on ayahuasca were administered personality measures and a semi-structured interview about phenomenal qualities of their experience. Ayahuasca ingestion was associated with profound alterations (...) of temporal- spatial experiences including expansive space and slowed time. Ayahuasca use was also associated with positive emotional states, higher levels of fantasy proneness and psychological absorption and a greater openness to mystical experiences. Conversely, quickened time was associated with negative emotionality. The results are discussed within a multi-faceted model of fringe consciousness with a particular emphasis on Hunt's (1995) models of cross-modal translation as the basis for higher-order symbolic cognition and support James' (1890/1950) contention that fringe consciousness is essential to human cognition.

This article explores the law and ethics of lobbying. The legal discussion examines disclosure regulations, employment restrictions,bribery laws, and anti-fraud provisions as each applies to the lobbying context. The analysis demonstrates that given the social value placed on the First Amendment, federal law generally affords lobbyists wide latitude in determining who, what, when, where, and how to lobby.The article then turns to ethics. Lobbying involves deliberate attempts to effect changes in the law. An argument is advanced that because law implicates (...) the use of force and because law ideally reflects the values of a democratic society, seeking to slant the law to serve a client’s narrow interests cannot provide an adequate ethical end for a lobbyist. On the contrary, a lobbyist has an affirmative moral duty to seek reasonably balanced and just laws. The article examines, refines, and defends this proposition in a number of settings. (shrink)

Plato's "laches" is an investigation into the nature of courage with the intention of demonstrating the difficulty of singling out one virtue, namely courage, and defining it separately from the other cardinal virtues such as bravery, wisdom, justice, temperance, and piety. As the dialogue proceeds it becomes evident that socrates not only relates courage with the battlefield, but also with other spheres of life. Of special interest is his reference of being courageous regarding desires and pleasures where an overlap of (...) virtues is anticipated. This extension of the range of manifestations of courage indicates that his conception of courage transcends the traditional one in which he hints at a new sort of unity of courage and temperance, and on the other of courage and justice. One of plato's main aims in writing this dialogue was to mark out the intellectual limits of the two generals' positions, especially that of nicias, whose philosophical position could appear to be deceptively similar to the socratic one which he did not fully understand.

Stefan Collini's Absent Minds is a rich, critical history of a cliché: that English culture is peculiarly hostile to intellectuals. Despite striking differences in the organization of intellectual life in the U.S. and Britain, precisely the same cliché pervades American writing. The explanation may lie less in structure than in the transnational mobility of the language of the intellectual.

Spatial attention and eye-movements are tightly coupled, but the precise nature of this coupling is controversial. The influential but controversial Premotor theory of attention makes four specific predictions about the relationship between motor preparation and spatial attention. Firstly, spatial attention and motor preparation use the same neural substrates. Secondly, spatial attention is functionally equivalent to planning goal directed actions such as eye-movements (i.e. planning an action is both necessary and sufficient for a shift of spatial attention). Thirdly, planning a goal (...) directed action with any effector system is sufficient to trigger a shift of spatial attention. Fourthly, the eye-movement system has a privileged role in orienting visual spatial attention. This article reviews empirical studies that have tested these predictions. Contrary to predictions one and two there is evidence of anatomical and functional dissociations between endogenous spatial attention and motor preparation. However, there is compelling evidence that exogenous attention is reliant on activation of the oculomotor system. With respect to the third prediction, there is correlational evidence that spatial attention is directed to the endpoint of goal-directed actions but no direct evidence that this attention shift is dependent on motor preparation. The few studies to have directly tested the fourth prediction have produced conflicting results, so the extent to which the oculomotor system has a privileged role in spatial attention remains unclear. Overall, the evidence is not consistent with the view that spatial attention is functionally equivalent to motor preparation so the Premotor theory should be rejected, although a limited version of the Premotor theory in which only exogenous attention is dependent on motor preparation may still be tenable. A plausible alternative account is that activity in the motor system contributes to biased competition between different sensory representations with the winner of the competition becoming the attended item.

This article explores the motives underlying corporate responses to the COVID-19 pandemic. The analysis begins with Thomas Dunfee’s Statement of Minimum Moral Obligation, which specifies, more precisely than any other contribution to the business ethics canon, the level of corporate beneficence required during a pandemic. The analysis then turns to Milton Friedman’s neoliberal understanding of human nature, critically contrasting it with the notion of stoic virtue that informs the works of Adam Smith. Friedman contends that beneficence should play no role (...) in corporate settings. Smith, by contrast, emphasizes the need for prudence, beneficence and self-command in all human endeavours. The article then uses these competing frameworks to reflect on a published survey of 145 corporate responses to COVID-19. In many of these responses, the benefit to a non-financial stakeholder is clear, while the financial consequence to the firm remains nebulous. This supports the contention that during a pandemic, beneficence provides a more complete explanation of many corporate actions than the profit motive alone. The article contests Friedman’s Chicago School profit imperative and goes beyond Dunfee’s SMMO by endorsing the more full-throated embrace of beneficence and stoic virtue found in the works of Smith.

Aristotle on the Perfect Life may be viewed as part of such a detailed study. In this book, Kenny discusses a series of topics relating to the central Aristotelian concept of the supreme good, and compares the treatment of these topics in the two treatises. He devotes separate discussions to the notions of finality, perfection, and self-sufficiency as attributes of the supreme good. He also considers the way in which friendship and good fortune relate to happiness. A theme which recurs (...) throughout the book is the divergent ways in which the EE and the NE conceive the relationship between moral excellence, contemplation and happiness. In some cases Kenny suggests that the EE offers a subtler treatment than the NE; in other cases he argues that the EE presents a more coherent, more plausible, position. Are we in a position, then, to conclude with confidence that the EE is the later, more authoritative, treatise? Kenny does not draw such a conclusion. One comes away with the impression that although he leans towards this conclusion, he also believes that still more work, especially on the EE, is needed. (shrink)

ARISTOTLE thought his predecessors in general, and Plato in particular, made a serious mistake in failing to mark the boundaries separating the different sciences and branches of philosophical inquiry. All of them failed to grasp the fundamental distinction between practical and theoretical knowledge. Ethics and politics, the prime examples of practical knowledge, differ from such theoretical sciences as metaphysics and physics not only in their aims but in their methods and subject matter as well. Indeed, Aristotle thinks the differences are (...) such that we cannot regard practical and theoretical knowledge as two species of a single genus, for there is no common definition of knowledge which applies to both.

This study explores the legal and ethical issues associated with contract pricing. In particular, it focuses on a set of legal precedents which have addressed the enforceability of allegedly unfair contract prices. Traditionally, the common law has emphasized the consent of the parties. If the parties consented to a given price; it is presumptively fair and enforceable. The cases reviewed in this study, however, seem to draw upon alternative moral conceptions of fairness not normally associated with the common law. The (...) analysis begins by distinguishing the traditional legal conception of fairness from alternative moral conceptions. The cases are then read with a critical eye so as to tease out the underlying principles which best explain them. The analysis illustrates that, notwithstanding judicial rhetoric to the contrary, the courts continue to employ the traditional legal notion of fairness, to the exclusion of alternative moral concerns. The study clarifies an otherwise murky area of the law and illustrates that the legal meaning of fairness differs greatly from the moral one. (shrink)
