Listening to someone from some distance in a crowded room you may experience the following phenomenon: when looking at them speak, you may both hear and see where the source of the sounds is; but when your eyes are turned elsewhere, you may no longer be able to detect exactly where the voice must be coming from.

This ‘ventriloquist’ effect reflects the ways in which visual cognition can dominate auditory perception.

What is the correct procedure for determining the contents of perception? Philosophers tackling this question increasingly rely on empirically-oriented procedures in order to reach an answer. I argue that this constitutes an improvement over the armchair methodology constitutive of phenomenal contrast cases, but that there is a crucial respect in which current empirical procedures remain limited: they are unimodal in nature, wrongly treating the senses as isolatable faculties. I thus have two aims: first, to motivate a reorientation of the admissible (...) contents debate into a multimodal framework, charting its various significances. The second is to explore whether any experimental studies of multimodal perception support a so-called Liberal (or ‘high-level’ or ‘rich’) account of perception’s admissible contents. I conclude that the McGurk effect and the ventriloquist effect are both explicable without the postulation of high-level content, but that at least one multimodal experimental paradigm may necessitate such content: the rubber hand illusion. One upshot of this argument is that Conservatives who claim that the Liberal view intolerably broadens the scope of perceptual illusions, particularly from the perspective of perceptual psychology, should pursue other arguments against that view.

Multisensory processing encompasses all of the various ways in which the presence of information in one sensory modality can adaptively influence the processing of information in a different modality. In Part I of this survey article, I begin by presenting a cartography of some of the more extensively investigated forms of multisensory processing, with a special focus on two distinct types of multisensory integration. I briefly discuss the conditions under which these different forms of multisensory processing occur as well as (...) their important perceptual consequences and interrelations. In Part II, I then turn to examining of some of the different possible ways in which the structure of conscious perceptual experience might also be characterized as multisensory. In addition, I discuss the significance of research on multisensory processing and multisensory consciousness for philosophical attempts to individuate the senses. (shrink)

Cognitive scientists have long known that the modalities interact during perceptual processing. Cross-modal illusions like the ventriloquism effect show that the course of processing in one modality can alter the course of processing in another. But how do the modalities interact in the specific domain of object perception? This paper distinguishes and analyzes two kinds of multisensory interaction in object perception. First, the modalities may bind features to a single object or event. Second, the modalities may cooperate when (...) differentiating an object or event from its surroundings. I critically evaluate evidence for various forms of multisensory binding. I then consider the case for multisensory differentiation. I argue that existing evidence for multisensory differentiation is inconclusive. I highlight ways that the issue might be empirically resolved. (shrink)

This chapter distinguishes between two kinds of ordinary multisensory experience that go beyond mere co-consciousness of features (e.g., the experience that results from concurrently hearing a sound in the hallway and seeing the cup on the table). In one case, a sensory experience in one modality creates a perceptual demonstrative to whose referent qualities are attributed in another sensory modality. For example, when you hear someone speak, auditory experience attributes audible qualities to a seen event, a person’s speaking motions. The (...) second kind of multisensory experience attributes features experienced in several sensory modalities to one and the same object via a process of amodal perceptual integration, i.e., integration that occurs separately from processing within the individual sensory modalities. Multisensory experiences arising from holding and seeing a tomato or from seeing the Indian curry boil and smelling it are examples of the second kind of multisensory experience. At the end of the chapter we look at synesthesia, a kind of atypical multisensory experience, and argue that one version of this phenomenon may be able to shed light on the neural mechanism underlying amodally integrated multisensory experience.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Socrates Dissatisfied: An Analysis of Plato’s Crito by Roslyn WeissMark L. McPherranRoslyn Weiss. Socrates Dissatisfied: An Analysis of Plato’s Crito. New York: Oxford University Press, 1997. Pp. xii + 187. Cloth, $39.95.The speech by ‘the Laws’ of the Crito has commonly been understood as a case of Socratic ventriloquism, voicing a doctrine of authoritarian civic obligation that Socrates himself endorses. This, of course, generates the standard problem (...) of reconciling this docile son of Athens with the radically autonomous Socrates of the Apology, a man obedient only to the dictates of his own reason. Roslyn Weiss’s book sets out to challenge this mainstream reading.On Weiss’s account, the speech of the Laws is a piece of crafty Socratic rhetoric antithetical to Socrates’ own convictions. Its purpose, then, is to convince not the reader but the lawless and unphilosophical Crito that Socrates ought to remain in Athens, using terms that Crito can comprehend (terms that will benefit his soul by making him more law-abiding). Despite this false ‘oratory’ (50b6–8), however, Socrates’ own first allegiance is to “justice and philosophy” (3) whose principles dictate that he suffer the court’s judgment, “abiding by the things agreed to” at his trial (Cr. 50a2–3).Although others have argued for this thesis, this is the first book-length argument of its kind and it supersedes all previous attempts in its persuasiveness and its thorough and detailed treatment: sensitive not only to the dialogue’s Greek and argumentative structure, but also to its literary/characterological nuances, it establishes an important scholarly outpost on the interpretation of the Crito and a worthy challenge to Richard Kraut’s reading. It is, finally, written in a remarkably engaging, clean and effective style, addressing the secondary scholarship adequately, and providing a useful bibliography and general index (though, regrettably, no Index Locorum).The book essentially follows the text of the Crito in a series of nine chapters. After a short Introduction, Chapter 2 begins by portraying Socrates as an autonomous moral agent utterly devoted to justice; Chapter 3 distinguishes Crito from Socrates; Chapter 4 contends that 46b–50a outlines Socrates’ complete argument against escape (one compatible with the principles of the Apology); Chapter 5 unpacks Socrates’ hint at 50a–d that the Laws will be offering only rhetorical arguments; Chapter 6 outlines these arguments and their logical flaws; Chapter 7 addresses Socrates’ characterization of their effect as ‘Corybantic’ (54d); Chapter 8 explains how the Laws are able to “boost Crito to a higher rung on the moral ladder,” (6); and finally, Chapter 9 reaffirms the radical moral independence of Socrates.Provocative and impressive, the book is bound to provoke criticism and reservations in its readers. Here I can only record a sample of my own. First, it seems to me that Weiss’s desire to portray Socrates as a slave of reason and not the state leads her astray when she tries to account for Socrates’ apparent reliance on the extrarational (15–23). Weiss, for example, tries to map out a new third alternative to the opposition between Vlastos’ view that the daimonion is no more than a kind of subjective, contentless hunch and the Brickhouse, Smith and McPherran view that the daimonion can oppose and ‘trump’ the results of rational deliberation. As she sees it, for Socrates the daimonion is not a voice independent of, and in potential conflict with, his own thinking; rather, it is the voice of his own unconscious beliefs, restraining him for his own reasons from [End Page 620] doing what he is tempted to do in moments of weakness. There is much to be said against this account, but it will suffice to point out that whatever the true nature of the daimonion might have been, Socrates is not likely to have been sympathetic to Weiss’s analysis of it. All our evidence, after all, indicates that Socrates takes the cause of the daimonion to be a god or daimoôn in the traditional sense of those terms (see, e.g., Ap. 27b–28a). Weiss’s proposal also runs up against texts such as Lysis 218C4–8 and 215C4–5, where Socrates recounts an... (shrink)

Starting from the importance of the figure of the parrhesiastes — the political and therapeutic truth- teller— for Foucault’s understanding of the care of the self, this paper traces the political figuration of the analogy between philosophers and physicians on the one hand, and rhetors and disease on the other in Plato’s Gorgias. I show how rhetoric, in the form of ventriloquism, infects the text itself, and then ask how we account for the effect of the “ contaminated (...) ” philosophical dialogue on our readerly health. Is the text placebo, vaccine, or virus? All of these options, I argue, complicate Foucault’s prescription for parrhesia, requiring us to think anew the continuing political ramifications of the metaphor of care. (shrink)

“Female sexual dysfunction” is the type of contested disease that has sparked concern about the role of the pharmaceutical industry in medical science. Many policies have been proposed to manage industry influence without carefully evaluating whether the proposed policies would be successful. We consider a proposal for incorporating citizen stakeholders into scientific research and show, via a detailed case study of the pharmaceutical regulation of flibanserin, that such programs can be co-opted. In closing, we use Holman’s asymmetric arms race framework (...) as a tool for evaluating policies in industry-funded science. (shrink)

I argue that the epistemological virtues of concrete thinking, self-transparency, and narrative understanding developed by care ethicists can help international development practitioners combat their own temptations to engage in “unconscious unjustified paternalism” (UUP). I develop the concept of UUP—a type of paternalism in which one party unjustifiably substitutes her judgment for another's because of difficulty distinguishing her desires for the other from the other's good. I show that the temptation to UUP is endemic to development and that care ethics contains (...) virtues for combating it. Key to my claim is a view of caregiving as a practice of negotiating conflict. (shrink)

Each of the following claims has been defended in the scientific literature on free will and consciousness: your brain routinely decides what you will do before you become conscious of its decision; there is only a 100 millisecond window of opportunity for free will, and all it can do is veto conscious decisions, intentions, or urges; intentions never play a role in producing corresponding actions; and free will is an illusion. In Effective Intentions Alfred Mele shows that the evidence offered (...) to support these claims is sorely deficient. He also shows that there is strong empirical support for the thesis that some conscious decisions and intentions have a genuine place in causal explanations of corresponding actions. In short, there is weighty evidence of the existence of effective conscious intentions or the power of conscious will. Mele examines the accuracy of subjects' reports about when they first became aware of decisions or intentions in laboratory settings and develops some implications of warranted skepticism about the accuracy of these reports. In addition, he explores such questions as whether we must be conscious of all of our intentions and why scientists disagree about this. Mele's final chapter closes with a discussion of imaginary scientific findings that would warrant bold claims about free will and consciousness of the sort he examines in this book. (shrink)

"Like ventriloquial dummies, artworks take on personalities, characters of their own, often saying what the artist herself would or could not say in voices distinct from her daily modes of expression. Goldblatt uses ventriloquism as an apt metaphor to help understand a variety of art-world phenomena - how the vocal vacillation between ventriloquist and dummy is mimicked in the relationship of artist, artwork and audience, including the ways in which artworks are interpreted. Moreover, Goldblatt employs the concept of (...) class='Hi'>ventriloquism to generate insights into many of our important philosophers' writings on the arts, discussing the work of Nietzsche, Foucault, Derrida, Cavell, and Wittgenstein, among others."--BOOK JACKET.

Is it possible to donate unpaired vital organs, foreseeing but not intending one's own death? We argue that this is indeed psychologically possible, and thus far agree with Charles Camosy and Joseph Vukov in their recent paper on 'double effect donation.' Where we disagree with these authors is that we see double effect donation not as a morally praiseworthy act akin to martyrdom but as a morally impermissible act that necessarily disrespects human bodily integrity. Respect for bodily integrity (...) goes beyond avoiding the aim to kill: not all side effects of deliberate bodily interventions can be outweighed by intended benefits for another even if the subject fully consents. It is not any necessary intention to kill or harm another or oneself that makes lethal donation/harvesting illicit but the more immediate intention to accept or perform surgery on an (innocent) person combined with the foresight of lethal harm and no health-related good for him or her. Double effect donation falls foul of the first condition of double effect reasoning in that the immediate act is wrong in itself. We argue further that the wider effects of such donation would be socially disastrous and corrupting of the medical profession: doctors should retain a sense of nonnegotiable respect for bodily integrity even when they intervene on willing subjects for the benefit of others.

Attention is automatically allocated to stimuli that are opposite in valence to the current motivational focus (Rothermund, 2003; Rothermund, Voss, & Wentura, 2008). We tested whether this incongruency effect is due to affective–motivational counter-regulation or to an increased salience of stimuli that mismatch with cognitively activated information. Affective processing biases were assessed with a search task in which participants had to detect the spatial position at which a positive or negative stimulus was presented. In the motivational condition, positive or (...) negative affective–motivational states were induced by performance feedback after each trial. In the cognitive activation condition, participants memorised the word “good” or “bad” during the search task. The affective incongruency effect was replicated in the motivational condition, whereas an affective congruency effect obtained in the cognitive activation condition. These findings support an explanation of affective incongruency effects in terms of automatic counter-regulation that is motivational in nature. (shrink)

Effective altruism sounds so innocuous—who could possibly be opposed to doing good more effectively? Yet it has inspired significant backlash in recent years. This paper addresses some common misconceptions and argues that the core “beneficentric” ideas of effective altruism are both excellent and widely neglected. Reasonable people may disagree on details of implementation, but all should share the basic goals or values underlying effective altruism.

The Effect: An Introduction to Research Design and Causality is about research design, specifically concerning research that uses observational data to make a causal inference. It is separated into two halves, each with different approaches to that subject. The first half goes through the concepts of causality, with very little in the way of estimation. It introduces the concept of identification thoroughly and clearly and discusses it as a process of trying to isolate variation that has a causal interpretation. (...) Subjects include heavy emphasis on data-generating processes and causal diagrams. Concepts are demonstrated with a heavy emphasis on graphical intuition and the question of what we do to data. When we "add a control variable" what does that actually do? (shrink)

The capacity to search for information effectively by asking informative questions is crucial for self-directed learning and develops throughout the preschool years and beyond. We tested the hypothesis that explaining observations in a given domain prepares children to ask more informative questions in that domain, and that it does so by promoting the identification of features that apply to multiple objects, thus supporting more effective questions. Across two experiments, 4- to 7-year-old children (N = 168) were prompted to explain observed (...) evidence or to complete a control task prior to a 20-questions game. We found that prior prompts to explain led to a decrease in the number of questions needed to complete the game, but only for older children (ages 6-7). Moreover, we found that effects of explanation manifested as a shift away from questions that targeted single objects. These findings shed light on the development of question asking in childhood and on the role of explanation in learning. (shrink)

Experimental philosophers have investigated various ways in which non‐epistemic evaluations can affect knowledge attributions. For example, several teams of researchers (Beebe and Buckwalter 2010; Beebe and Jensen 2012; Schaffer and Knobe 2012; Beebe and Shea 2013; Buckwalter 2014b; Turri 2014) report that the goodness or badness of an agent’s action can affect whether the agent is taken to have certain kinds of knowledge. These findings raise important questions about how patterns of folk knowledge attributions should influence philosophical theorizing about knowledge.

In 2013 the mayor's office of Bogotá organized the first ever Mujer T. The event, originally conceived as a beauty pageant, generated considerable controversy. Unexpectedly, however, most of the criticism came not from conservative groups, but from well-known cisgender feminist scholars who criticized the event from a traditional gender perspective. A heated debate about the needs, challenges, desires, and opportunities of trans women continued during the weeks prior to the event. The discussion played out through blogs, social media, and private (...) and public conversations. Nevertheless, although there was much talk about transwomen, there was little room for their voices. This article argues that because of the actors involved, the dynamics and content of the conversations, and the changes that took place in its aftermath, Mujer T 2013 highlights how trans people's bodies, expressions—whether related to gender, culture, or politics—and self-determination processes are intensely policed and contested, even by those whose explicit intent is to support and celebrate them. Therefore, understanding the dynamics of what happened around Mujer T 2013 has important lessons for the development of trans-inclusive policies and initiatives, feminist scholarship and practice, and institutional and societal change.

This research explores the intervention effect of the mindfulness acceptance insight commitment (MAIC) training program on the mindfulness level, flow state, and mental health of college swimmers. A sample of 47 college swimmers from a regular university was recruited and randomly divided into two groups before the intervention. Independent variables between groups are psychological training mode (MAIC training/no training), and the independent variable within group was time (pre-test, post-test, and continuity test). The dependent variables are mindfulness level, flow state, (...) and mental health (anxiety, depression, training, and competition satisfaction). Results show that after the intervention of MAIC training, the mindfulness level of athletes’ flow state has been significantly improved, whereas anxiety and depression significantly decreased. In addition, the satisfaction with training and competition significantly improved. In the continuous stage after the intervention, the mindfulness level, flow state, and mental health of athletes are still significantly higher than those in the pre-test. The comparison of the post-test and continuity test show no significant differences in the mindfulness level, flow state, depression, and training and competition satisfaction of athletes. Still, the anxiety level shows an upward trend with a significant difference. This study demonstrates that the MAIC mindfulness training program can significantly improve the mindfulness level, flow state, anxiety, depression, and training and competition satisfaction of college swimmers with a good continuity effect. Thus, the athletes’ sports experience can be improved, and good psychological benefits can be attained. (shrink)

The object of this study was to investigate whether level of processing (LOP) modulates enhanced memory performance for emotional stimuli, and, if so, whether the LOP effects relate to their gist and details. During the study phase, participants were presented with colourful pictures with negative, neutral and positive valences and encoded the emotional pictures under either a semantic (living/non-living judgement) or a perceptual (left/right position judgement) condition. During the test phase, they judged whether the presented picture was old or new (...) in Experiments 1 and 2, and also judged whether a specific concept, labelled using words, had been studied in Experiment 2. The results showed that under both encoding conditions, the details of both negative and positive pictures were recognised better than those of neutral pictures. Also, the gist of negative pictures was recognised better than that of neutral pictures but only under the semantic condition. These data provide evidence that the LOP differentially modulates enhanced emotional memory for gist and details of pictures. (shrink)

Adopting a communication as constitutive of organization (CCO) perspective on ethics and corporate social responsibility (CSR) invites us to create the conditions of a dialogue, discussion, or debate between various stakeholders, who can then try to confront their respective positions on a given issue, and possibly come to a decision regarding how a situation should be evaluated and/or responded to. As shown in this article, getting human stakeholders to voice their concerns about a specific situation is a way not only (...) to rationally confront multiple viewpoints on what should be done about it (à la Habermas) but also to allow elements of this situation to reveal themselves in a discussion. This is why any ethical decision has to experience a form of undecidability and surprisability. When beliefs and opinions can be called into question, it means that participants are ready to become attentive to what a situation might surprisingly call for. Communication is therefore a matter of ventriloquism, as human participants should also be considered the means by which elements of a situation manage to express themselves in a discussion, dictating specific courses of action over others. This concretely means that multiple voices can be heard in such a scene: not only the voices of the human stakeholders who speak to each other but also the voices of facts, principles, future generations, ecosystems, populations that are made to say things through these various turns of talk.

People are adept at inferring novel causal relations, even from only a few observations. Prior knowledge about the probability of encountering causal relations of various types and the nature of the mechanisms relating causes and effects plays a crucial role in these inferences. We test a formal account of how this knowledge can be used and acquired, based on analyzing causal induction as Bayesian inference. Five studies explored the predictions of this account with adults and 4-year-olds, using tasks in which (...) participants learned about the causal properties of a set of objects. The studies varied the two factors that our Bayesian approach predicted should be relevant to causal induction: the prior probability with which causal relations exist, and the assumption of a deterministic or a probabilistic relation between cause and effect. Adults’ judgments (Experiments 1, 2, and 4) were in close correspondence with the quantitative predictions of the model, and children’s judgments (Experiments 3 and 5) agreed qualitatively with this account.

A period of exposure to trains of simultaneous but spatially offset auditory and visual stimuli can induce a temporary shift in the perception of sound location. This phenomenon, known as the 'ventriloquist aftereffect', reflects a realignment of auditory and visual spatial representations such that they approach perceptual alignment despite their physical spatial discordance. Such dynamic changes to sensory representations are likely to underlie the brain's ability to accommodate inter-sensory discordance produced by sensory errors (particularly in sound localization) and variability in (...) sensory transduction. It is currently unknown, however, whether these plastic changes induced by adaptation to spatially disparate inputs occurs automatically or whether they are dependent on selectively attending to the visual or auditory stimuli. Here, we demonstrate that robust auditory spatial aftereffects can be induced even in the presence of a competing visual stimulus. Importantly, we found that when attention is directed to the competing stimuli, the pattern of aftereffects is altered. These results indicate that attention can modulate the ventriloquist aftereffect. © 2010 Elsevier B.V. (shrink)

'Sound Effects' collects original articles on English and American prose fiction which analyse vocal phenomena by using the psychoanalytic concept of the object voice - introduced by J. Lacan and theorised by M. Dolar - as their interpretative tool.

Hume’s ethics is concerned not only with the metaphysical status of moral qualities but equally, if not more, with the problem of determining to what extent and under what conditions issues of moral disagreement and inquiry can be decided by rational argumentation. This paper argues that Hume’s solution to the second problem is a form of perspectivism: the rational decidability of moral issues depends on the existence of shared perspectives, or sets of assumptions and correlated dispositions to feelings, and is (...) largely independent of the metaphysical status of moral qualities. An issue of disagree- ment may thus be rationally decidable among people with certain dispositions to feeling but not among others. A similar perspectivist reading is suggested for Hume’s analysis of knowledge about causes and effects. (shrink)

The effect of germanium addition on the physical properties, i.e. density, molar volume, compactness, number of lone-pair electrons, average coordination number, heat of atomization, mean bond energy, cohesive energy and glass-transition temperature, of (Se80Te20)100− x Ge x (x = 0, 2, 4, 6) bulk glassy alloys was investigated. The density of the glassy alloys is found to decrease with increasing Ge content. The molar volume and compactness of the structure of the glass were determined from the measured density. The (...) mean bond energy is proportional to the glass-transition temperature. The cohesive energy of the samples has been calculated using a chemical bond approach and is correlated with an increase in the optical energy gap with increase in the Ge content. The heat of atomization was also calculated and correlated with the optical energy gap. The glass-transition temperature has been estimated using different methods and is found to increase with an increase of Ge content. (shrink)

From Arthur Schopenhauer we can glean a characteristically moody perspective on the primordial condition of speaking and being spoken. Focusing on his dualistic view of the embodied subject as having to contend with the forces of both Will and presentation, in this article I argue that his philosophy construes communication as a sort of weird ventriloquism. Drawing on François Cooren’s proposed method of ‘ventriloqual analysis’, I re-examine Schopenhauer’s subject as a being that both animates and is animated by his (...) strange dark noumena. Bearing witness to this eerie metaphysical stagecraft, his concept of Will becomes synonymous with a will to communicate, which manifests itself through the voice of the speech actor and allows us to think about his ontology and ethics from a different rhetorical perspective.

Integrating stakeholder agency theory with the instrumental corporate social responsibility (CSR) literature, this study explores how award-winning CEOs consider personal interests and balance competing stakeholder demands when they decide between external and internal CSR, or CSR focus. Using a difference-in-differences research design, we find that after winning a prestigious media award, CEOs engage in more external CSR, which is more visible to the public, and less internal CSR, which is less likely to attract public attention. We find that such an (...) influence on CSR focus is more salient for award-winning CEOs with lower stock ownership (i.e. a stronger self-serving motivation) than for CEOs with higher stock ownership. Furthermore, we explore the role of stakeholder salience in modifying award-winning CEOs’ decisions about CSR focus. When external stakeholder salience is higher (e.g. higher media coverage), award-winning CEOs' manipulation of CSR focus by increasing external CSR and decreasing internal CSR is more salient. However, such effects can be dampened when internal stakeholder salience is higher (e.g. higher human capital intensity). Our study contributes to the instrumental CSR literature by demonstrating the underlying processes and boundary conditions of how awards affect CEOs' balance of stakeholder salience. (shrink)

Measuring the effectiveness of medical interventions faces three epistemological challenges: the choice of good measuring instruments, the use of appropriate analytic measures, and the use of a reliable method of extrapolating measures from an experimental context to a more general context. In practice each of these challenges contributes to overestimating the effectiveness of medical interventions. These challenges suggest the need for corrective normative principles. The instruments employed in clinical research should measure patient-relevant and disease-specific parameters, and should not be sensitive (...) to parameters that are only indirectly relevant. Effectiveness always should be measured and reported in absolute terms (using measures such as 'absolute risk reduction'), and only sometimes should effectiveness also be measured and reported in relative terms (using measures such as 'relative risk reduction')-employment of relative measures promotes an informal fallacy akin to the base-rate fallacy, which can be exploited to exaggerate claims of effectiveness. Finally, extrapolating from research settings to clinical settings should more rigorously take into account possible ways in which the intervention in question can fail to be effective in a target population.

I distinguish between two kinds of selection effects on experience: selection of objects or features for experience, and anti-selection of experiences for cognitive uptake. I discuss the idea that both kinds of selection effects can lead to a form of confirmation bias at the level of perception, and argue that when this happens, selection effects can influence the rational role of experience.

Despite the conceptual problems in identifying the placebo effect, an increasing number of multidisciplinary inquiries rest on the assumption that there is a distinct class of effects, placebo effects. In this chapter, I argue against this assumption. I present cases and characterizations of the placebo effect as offered in the literature, and argue that the latter are subject to insurmountable problems. Moreover, I argue that identification of placebo effects as such is not useful for the three main purposes (...) offered in the literature. I then offer suggestions for why it may remain intuitive that some effects are placebo effects and close by noting the potential benefits of ultimately explaining away these intuitions. (shrink)
