The outlines of a novel, fully naturalistic theory of perception are provided, that can explain perception of an object X by organism Z in terms of reflexive causality. On the reflexive view proposed, organism Z perceives object or property X just in case X causes Z to acquire causal dispositions reflexively directed back upon X itself. This broadly functionalist theory is potentially capable of explaining both perceptual representation and perceptual content in purely causal terms, making no use of (...) informational concepts. However, such a reflexive, naturalistic causal theory must compete with well entrenched, supposedly equally naturalistic theories of perception that are based on some concept of information, so the paper also includes some basic logical, naturalistic and explanatory criticisms of such informational views.

Images of nature abound in the practice of international environmental law but their significance in law is unclear. Drawing on visual jurisprudence, and interpretative methods for visual art, this book analyses photographs for their representations of nature's aesthetic value in treaty processes that concern world heritage, whales and biodiversity. It argues that visual images should be embraced in the prosaic practice of international law, particularly for treaties that demand judgements of nature's aesthetic value. This environmental value is in practice conflated (...) with natural beauty, ethical and cultural values, and displaced by economic and scientific values. Interpretations of visual images can serve instead to critique and conceive sensory, imaginative and emotional appreciations of nature from different cultural perspectives as proposed by philosophers of environmental aesthetics. Addressing questions of value and the visual, this landmark book shows how images can be engaged by nations to better protect the environment under international law. (shrink)

I survey some unusual phenomena in which the body seems to be projected into other things. I argue that these phenomena should not be understood as illusions, as erroneous distortions of an objective body, but as indicating that the body is first of all a being absorbed in outside things. The usual questions about perception are thus reversed: the question is not how the outside world is represented in an inside, but how a moving body ecstatically absorbed in things (...) ever breaks out of that absorption. My suggested answer involves movement and has implications for rethinking nature. (shrink)

John Foster presents a penetrating investigation into the question: what is it to perceive a physical object? Is perceptual contact with a physical object, he asks, something fundamental, or does it break down into further factors? If the latter, what are these factors, and how do they combine to secure the contact? For most of the book, Foster addressed these questions in the framework of a realist view of the physical world. But the arguments which thereby unfold - arguments which (...) undermine direct realism and establish a version of the sense-datum theory - lead to the conclusion that we do no perceive physical objects at all. The only way to avoid this conclusion is by abandoning physical realism for a form of idealism, and this is the option which Foster finally embraces. The Nature of Perception makes an important contrbution to the ongoing debate: it sheds fresh light on the traditional issues, and breathes new life into positions which most current philosophers assumeto be dead.

This chapter focuses on one of the common fallacies in Western philosophy: the constructive nature of human perception. Many of the things that we believe are generated by our senses interacting with the outside world. Our brains make decisions about what information to interpret and how to do so mostly based on our assumptions, preconceptions, and desires. An assumption that informs how we interpret the information that our brain receives is that the size, color, and shape of objects is (...) constant. This allows us to perceive an object the same way even if how we are seeing it is changing. There are of course countless visual illusions that demonstrate this fact. This is why science has proved to be such a powerful tool in understanding the world; it is designed specifically to guard against the way our senses can lead us astray. (shrink)

Theory-ladenness of perception and cognition is pervasive and variable. Emerging maturationally natural perception and cognition, which are on-line, fast, automatic, unconscious, and, by virtue of their selectivity, theoretical in import, if not in form, define normal development. They contrast with off-line, slow, deliberate, conscious perceptual and cognitive judgments that reflective theories, including scientific ones, inform. Although culture tunes MN systems, their emergence and operation do not rely on culturally distinctive inputs. The sciences advance radically counter-intuitive representations that (...) depart drastically from MN systems’ deliverances. Extensive experience with RCI scientific theories can result in a practiced naturalness with their perceptual and cognitive consequences; nevertheless, automatic MN verdicts persistently intrude. Fodor suggests that the uniformity of the biases MN systems introduce can serve as a theory-neutral means for adjudicating scientific disputes. Findings about vision challenge Fodor’s proposal for circumventing problems that MN theory-ladenness presents. These considerations indicate that RCI scientific ideas are difficult to learn, master, and deploy; consequently, the corrective import of science’s social and institutional arrangements plays a critical role in its epistemic stature.

The author defends the naturalizing program of the notion of representation against the primitivist view according to which the notion of representation as belonging to psychology as a mature science is irreducible. First, the author concedes that the original teleological project trivializes the concept of representation by applying it to bacteria, protozoa, amoeba, when the best available explanation is the assumption that primitive organisms and artifacts are merely indicating proximal stimulation rather than representing the distal causes of stimulation. Yet, the (...) author does not believe that this presents an unsurmountable obstacle for the naturalizing program when what is in question is genuine sensory representation, namely perception. In the author’s view, what matters for the naturalizing program are not cases in which the concept of representation is misemployed, but rather cases in which the focus is genuine sensory representation, that is, genuine perceptions; or so he shall argue.

In lieu of an abstract, here is a brief excerpt of the content:150 PERCEPTIONS, OBJECTS AND THE NATURE OF MIND In this paper I consider the relation between perceptions and objects for Hume and the bearing which this has on his conception of the mind as composed of perceptions. But first it is necessary to distinguish at least two senses in which he uses the term 'object'. In the first, "perceptions of the human mind" — both impressions and ideas — (...) are referred to as "our objects" (T 1,2). Objects in this sense are intentional objects. Hume almost consistently uses the noun 'perception', rarely the verb 'to perceive'. This serves to emphasize that for him perception is an object, not the perceiving of an object — a departure from the tradition of Locke and Berkeley for whom perceptions are cognitive acts having objects. That perception is not conceived by Hume as a cognitive act or form of awareness but purely as an object of awareness is evident when he says, For since all actions and sensations of the mind are known to us by consciousness, they must necessarily appear in every particular what they are, and be what they appear. Everything that enters the mind, being in reality a perception, 'tis impossible anything shou'd to feeling appear different. This were to suppose, that even when we are most intimately conscious, we might be mistaken (T 190). 1 Or again, "The only existences, of which we are certain, are perceptions, which being immediately present to us by consciousness, command our strongest assent...." (T 212). In its other sense the term 'object' is used to denote bodies, or that to which we attribute a continued existence "distinct from the mind and perception", or, borrowing Locke's expression "external 151 objects". It is just because we attribute a continued and independent existence to bodies that we distinguish them from perceptions, for "all impressions are internal and perishing existences, and appear as such" (T 194). But while we make this distinction in our everyday role of common man, the difference between a perception and an (external) object is really only a difference between two types of perceptions, on the one hand those that are characterized in their occurrence by constancy and coherence, and on the other those, for example the passions, which exhibit a different type of "regularity" in their occurrence (T 195). The constancy and coherence which some perceptions exhibit, together with a natural tendency of the mind "to bestow on the objects a greater regularity than what is observ'd in our mere perceptions" (T 197) causes us to attribute to these perceptions an uninterrupted and independent existence, an existence which is, of course, fictitious, because all perceptions are really internal and perishing. 'Tis certain, that almost all mankind, and even philosophers themselves, for the greatest part of their lives, take their perceptions to be their only objects, and suppose, that the very being, which is intimately present to the mind, is the real body or material existence (T 206). This is not to say, however, that "what any common man means by a hat, or shoe, or stone" (T 202) he also believes to be a perception. What he does believe is that the hat or the shoe is immediately present to the mind, or directly appears to his consciousness. It is Hume, the philosopher, who is here interposing the philosophical doctrine that "no beings are ever present to the mind but perceptions" (T 212). This is, of course, not an empirical generalization. It is the definition of a perception as "whatever can be present 152 to the mind" (Abstract 647). It is this definition which gives sense to the statement "their perceptions are their only objects", the term "objects" here referring to "external objects". And the common man would, no doubt, be surprised to learn that these hats, shoes, etc., which directly appear to his consciousness, are by that circumstance really only his own perceptions which he has imagined, falsely, to have a continued and independent existence. Only a few experiments, however, are needed for the philosopher to realize that perceptions, i.e., what is present to the mind, do not have a continued and independent existence. Unable to give up his vulgar... (shrink)

Gary Hatfield examines theories of spatial perception from the seventeenth to the nineteenth century and provides a detailed analysis of the works of Kant and Helmholtz, who adopted opposing stances on whether central questions about spatial perception were fully amenable to natural-scientific treatment. At stake were the proper understanding of the relationships among sensation, perception, and experience, and the proper methodological framework for investigating the mental activities of judgment, understanding, and reason issues which remain at the (...) core of philosophical psychology and cognitive science.

Movement perception and its role in aesthetic experience have been often studied, within empirical aesthetics, in relation to the human body. No such specificity has been defined in neuroimaging studies with respect to contents lacking a human form. The aim of this work was to explore, through functional magnetic imaging (fMRI), how perceived movement is processed during the aesthetic judgment of paintings using two types of content: human subjects and scenes of nature. Participants, untutored in the arts, were shown (...) the stimuli and asked to make aesthetic judgments. Additionally, they were instructed to observe the paintings and to rate their perceived movement in separate blocks. Observation highlighted spontaneous processes associated with aesthetic experience, whereas movement judgment outlined activations specifically related to movement processing. The ratings recorded during aesthetic judgment revealed that nature scenes received higher scored than human content paintings. The imaging data showed similar activation, relative to baseline, for all stimuli in the three tasks, including activation of occipito-temporal areas, posterior parietal and premotor cortices. Contrast analyses within aesthetic judgment task showed that human content activated, relative to nature, precuneus, fusiform gyrus and posterior temporal areas, whose activation was prominent for dynamic human paintings. In contrast, nature scenes activated, relative to human stimuli, occipital and posterior parietal cortex/precuneus, involved in visuospatial exploration and pragmatic coding of movement, as well as central insula. Static nature paintings further activated, relative to dynamic nature stimuli, central and posterior insula. Besides insular activation, which was specific for aesthetic judgment, we found a large overlap in the activation pattern characterizing each stimulus dimension (content and dynamism) across observation, aesthetic judgment and movement judgment tasks. These findings support the idea that the aesthetic evaluation of artworks depicting both human subjects and nature scenes involves a motor component, and that the associated neural processes occur quite spontaneously in the viewer. Furthermore, considering the functional roles of posterior and central insula, we suggest that nature paintings may evoke aesthetic processes requiring an additional proprioceptive and sensori-motor component implemented by “motor accessibility” to the represented scenario, which is needed to judge the aesthetic value of the observed painting.

Local perceptions of protected areas are important for conservation and the sustainability of protected areas. We undertook qualitative and ethnographic fieldwork to explore relationships between people and protected areas in the Blouberg mountain range, South Africa. The history of land use and current relationships with protected areas reveal legacies of marginalisation and immiseration, giving credence to a theory of traumatic nature. The impacts of traumatic nature manifest themselves in local discourses and narratives of nature, protected areas and conservation.

This contribution analyzes the rhetoric surrounding natural disasters in historiographic sources, challenging our assumptions about the eschatological nature of late antique and medieval historical consciousness. Contrary to modern expectations, a large number of late antique and medieval sources indicate that earthquakes and other natural disasters were understood as signs from God, relating to theophanic encounters or divine wrath in the present time. Building on recent research on premodern concepts of time and historical consciousness, the article underscores the fact (...) that eschatological models of time and history-that is, the relentless linear, teleological progression of time towards the End of Days-was not how premodern people perceived the relationship between past, present, and future. The textual evidence presented here is supported by a fragmented and littleknown illuminated historiographic text, the Ravennater Annalen, housed today in the cathedral library in Merseburg. This copy of a sixth-century illustrated calendar from Ravenna contains unique depictions of earthquakes in the form of giants breathing fire. Like the textual sources, this visual document should not be read as a premonition of the End of Days, rather it visualizes the belief that divine agency and wrath caused natural disasters. (shrink)

Review of Gary Hatfield, The Natural and the Normative: Theories of Spatial Perception from Kant to Helmholtz. MIT Press, 1990.

For scatterplots with gaussian distributions of dots, the perception of Pearson correlation r can be described by two simple laws: a linear one for discrimination, and a logarithmic one for perceived magnitude (Rensink & Baldridge, 2010). The underlying perceptual mechanisms, however, remain poorly understood. To cast light on these, four different distributions of datapoints were examined. The first had 100 points with equal variance in both dimensions. Consistent with earlier results, just noticeable difference (JND) was a linear function of (...) the distance away from r = 1, and the magnitude of perceived correlation a logarithmic function of this quantity. In addition, these laws were linked, with the intercept of the JND line being the inverse of the bias in perceived magnitude. Three other conditions were also examined: a dot cloud with 25 points, a horizontal compression of the cloud, and a cloud with a uniform distribution of dots. Performance was found to be similar in all conditions. The generality and form of these laws suggest that what underlies correlation perception is not a geometric structure such as the shape of the dot cloud, but the shape of the probability distribution of the dots, likely inferred via a form of ensemble coding. It is suggested that this reflects the ability of observers to perceive the information entropy in an image, with this quantity used as a proxy for Pearson correlation. (shrink)

Landscapes are shaped over time by the changing imaginaries that result from new representations of nature and the value associated with it. This paper discusses the evolving discourses which have shaped the perception of the landscape in two socially and ecologically significant contexts in Chile. The first is the central-southern region of the country, a large portion of which is now devoted to commercial forestry plantations. The second is the Patagonia-Aysén region, where since the 1990s, colonisation of a land (...) defined by a tradition of livestock rearing has evolved into a process epitomised by the slogan “Aysén, Life Reserve”. The representation that was made of central-southern Chile in the 50 'and 60' as a deforested and degraded land was the justification for promoting a new form of land occupation: the monoculture forest, designed and executed by a specific law. Forty years on from the passing of this law, the plantations of central-southern Chile have undergone a process of naturalisation. In this case, the exaltation of nature has been permanent. The only thing that changes is the definition of nature, which ended up including forest plantations. In Patagonia-Aysén, by the other side, there has been a marked shift in the rhetoric surrounding land. This has been particularly noticeable in the case of government bodies and private ecotourism companies, which have constructed an imaginary in line with a new model of economic development for the area. In a break with tradition, both the public and private sectors are beginning to shift their investment away from agricultural and livestock exploitation and towards ecotourism and conservation projects. In both cases, we analyse the manner in which transformations in perceptions and representations of landscape bring about new forms of land use, and how new focuses of value and social interest, forged within wider environmental discourses, have brought with them unexpected social consequences, like depopulation, economic transformations, cultural changes, etc. Thus, the aim of this work is to expose and discuss the reality and scope of new green discourses and their influence on the perception of natural landscapes in the Chilean neoliberal context.

Hamlyn's book is exactly what the subtitle says it is: a history of the philosophy of perception, where this is taken to be a part of what is now called the philosophy of mind, as distinguished from the theory of knowledge. He expounds and criticizes, clearly and carefully, the views of Western philosophers from the pre-Socratics to Ryle and Sartre, and in a final chapter of about ten pages he offers some conclusions of his own. He holds that "in (...) the primary sense, perception can signify any means whereby we come to recognize, identify or characterize something by means of the senses" ; that there is a conceptual connection between perception and sensation, in the sense that "an essential condition of our application of the concept of perception to a being of any kind is that such a being should have sense experiences or sensations" ; but that it is a mistake "to ask what experiences, processes or activities constitute perception... [although] this is just the question which has so often been asked in the history of philosophy and psychology". "An understanding of the concepts of sensation and perception comes... not by asking what experiences, processes or activities these terms stand for. It can come only as the result of an inquiry into the concepts which form the schemes to which these particular concepts belong". These schemes, Hamlyn says, center around the concept of knowledge, and include such concepts as those of identification, recognition, and awareness. (shrink)

This paper takes as its point of departure recent research into the possibility that human beings can perceive single photons. In order to appreciate what quantum perception may entail, we first explore several of the leading interpretations of quantum mechanics, then consider an alternative view based on the ontological phenomenology of Maurice Merleau-Ponty and Martin Heidegger. Next, the philosophical analysis is brought into sharper focus by employing a perceptual model, the Necker cube, augmented by the topology of the Klein (...) bottle. This paves the way for addressing in greater depth the paper’s central question: Just what would it take to observe the quantum reality of the photon? In formulating an answer, we examine the nature of scientific objectivity itself, along with the paradoxical properties of light. The conclusion reached is that quantum perception requires a new kind of observation, one in which the observer of the photon adopts a concretely self-reflexive observational posture that brings her into close ontological relationship with the observed.

The question addressed in this paper is whether particular emotional experiences or episodes of an emotion (such as two experiences of happiness) belong to a natural kind. The final answer to this question is that although some, even many, single episodes of an emotion may group into a natural kind, belonging to a natural kind is a highly contextual matter. The proposal relies on two premises. First, a conception of natural kind-hood that follows Boyd’s Homeostatic Property (...) Cluster Theory. Second, a view of emotional episodes that fits with the External Theory of Perception: typical emotional episodes are perceptual experiences of emotional affordances. After pointing out what candidates for emotional homeostatic properties could be like and suggesting some examples of emotional homeostatic mechanisms, the authors conclude that there are property clusters of emotional perceptions stabilized by homeostatic mechanisms. In spite of this, what counts as an emotional natural kind depends on many factors, not all of them natural: world properties, bodily and mental states of the agent, learning mechanisms that help us to satisfactorily navigate in the world, cultural differences that determine our perceptual style, as well as different interests which guide the explanation and prediction of emotional episodes.

How do therapists learn to manage sexual feelings in the therapeutic relationship in an ethical, responsible manner? Data from 293 university-based psychotherapists show that the minority who report that their training prepared them to do so "very well" were more likely to have received "content-specific" training related to the topic or an opportunity to explore themselves as sexual beings, or both. In addition, they had experience with supervisors who modeled the belief that sexual feelings are a normal, expected part of (...) any human relationship and must be anticipated and planned for by therapists.

Using the classroom as the unit of analyses, the current article discusses the methodological issues surrounding the literature with regard to the study of academic misconduct. Arguing for a shift in research, the present empirical investigation assesses the relationship between students' perceptions of classroom environment and academic misconduct by utilizing valid and reliable multidimensional measures with established constructs. By utilizing the classroom as the unit of analysis, a better understanding of the unique variance in academic dishonesty across classes may be (...) established in relation to variation in students' perceptions of teaching practices. One hundred twenty-eight classes participated in the current study, with 3,151 students completing the Students' Perceptions of Teacher Effectiveness survey and Academic Misconduct Survey. Although students' overall perceptions of teacher effectiveness were not related to the rate of academic misconduct across classes, results do suggest that the lower the difficulty and workload of the course is perceived as being, the more likely students report cheating on exams, taking credit for others' work, using false personal excuses, and creatively padding their work. Reasons for these relationships are explicated, and suggestions for future research are discussed. (shrink)

Meaning in sensory language is often built through figurative mechanisms, such as synesthetic metaphors, where a sensorial domain is used to talk about perceptions from a different sense, as in sweet[taste] texture[touch]. The motivation of synesthetic transfers of meaning has been studied in general and literary language, resulting in attempts to reveal universal patterns regarding the directionality of meaning transfer and sensorial conceptual preference. However, those universals have not been proven in any sensory Language for Specific Purposes (LSP). We a (...) sensory LSP corpus of olive oil tasing notes in English to explore the nature of these metaphors, test existent models and explanatory accounts and identify tendencies present in synesthetic meaning transfers. The computer-assisted semi-automatic scalable methodology followed consists of the innovative quasi-simultaneous identification of semantic incongruences and the classification of synesthetic expressions in the discourse according to the source and target sensorial domains. Results show the inadequacy of existent models to explain synesthetic behavior in olive oil tasting language. The patterns found are discussed in the light of cognitive constraints and LSP genre analysis to conclude that a multi-causal approach is needed to explain the motivation of synesthetic transfers of meaning.

This paper proposes a set of criteria for an appropriate experiment on the issue of the theory ladenness of perception. These criteria are used to select a number of experiments that use: belief-based ambiguous figures, fragmented figures, or memory color. Crucially, the data in experiments of this type are based on the participant’s qualitative visual experience. Across many different types of experimental designs, different types of stimuli, and different types of belief manipulation, these experiments show the impact of belief/theory (...) on visual perception. Using an ecological validity argument, I conclude that attention-based interpretations of these findings are not successful because the relevant epistemological issues only require that we examine final perception, in the sense of visual awareness of the everyday world. Finally, I argue that the epistemological consequences of theory-ladenness can be reduced by using a top-down/bottom-up theoretical framework and by adopting appropriate methodological procedures to data derived from individual observations.

Questions concerning perception are as old as the field of philosophy itself. Using the first-person perspective as a starting point and philosophical documents, the study examines the relationship between knowledge and perception. The problem is that of how one knows what one immediately perceives. The everyday belief that an object of perception is known to be a material object on grounds of perception is demonstrated as unreliable. It is possible that directly perceived sensible particulars are mind-internal (...) images, shapes, sounds, touches, tastes and smells. According to the appearance/reality distinction, the world of perception is the apparent realm, not the real external world. However, the distinction does not necessarily refute the existence of the external world. We have a causal connection with the external world via mind-internal particulars, and therefore we have indirect knowledge about the external world through perceptual experience. The research especially concerns the reasons for George Berkeley’s claim that material things are mind-dependent ideas that really are perceived. The necessity of a perceiver’s own qualities for perceptual experience, such as mind, consciousness, and the brain, supports the causal theory of perception. Finally, it is asked why mind-internal entities are present when perceiving an object. Perception would not directly discern material objects without the presupposition of extra entities located between a perceiver and the external world. Nevertheless, the results show that perception is not sufficient to know what a perceptual object is, and that the existence of appearances is necessary to know that the external world is being perceived. However, the impossibility of matter does not follow from Berkeley’s theory. The main result of the research is that singular knowledge claims about the external world never refer directly and immediately to the objects of the external world. A perceiver’s own qualities affect how perceptual objects appear in a perceptual situation. (shrink)

Résumé La théorie sémiotique s’est développée comme une théorie de la production du sens et de sa manifestation dans les diverses pratiques humaines. Dernièrement, elle est demandée à rendre compte de l’émergence du sens, de sa nature. Pour la philosophie merleaupontienne ce point d’origine est donné dans la perception, comme le premier sol où le sens se fait. La perception détient la primauté de la construction du monde signifiant pour l’homme. Dans les sciences naturelles, les neurosciences pointent vers (...) le cerveau, en particulier l’équipement neuronal que nous avons en tant qu’hommes, comme le siège de la construction du sens. Notre connaissance du monde vient d’une « neuroception », un néologisme inévitable pour lui donner un air de famille avec celui de la « per-ception ». Devant ces deux positions théoriques, nous pouvons en sémiologie et linguistique offrir et défendre l’hypothèse que notre connaissance du monde est péremptoirement générée dans les mailles des langages. Une opération de sémioception, basée sur l’acte sémiologique arbitraire des langages, commande la perception humaine elle-même, avec antécédence. Ce n’est pas le cerveau qui « fait de l’esprit », c’est plutôt le langage qui « fait le cerveau » humain. (shrink)

Pylyshyn's target article argues that perception is not inferential, but this is true only under a narrow construal of inference. A more general construal is possible, and has been used to provide formal theories of many visual capacities. This approach also makes clear that the evolution of natural constraints need not converge to the “veridical” state of the world.

Following his earlier books The Case for Idealism and The Immaterial Self John Foster once again defends a form of idealism. For much of this book, however, idealism remains in the background. Instead, the focus is on theories of perception; Foster examines what purports to be an exhaustive taxonomy of physical realist theories of perception and, finding each one wanting, portrays idealism as the only acceptable alternative. The arguments, a selection of which are summarized below, are highly organized (...) and clearly expressed but make relatively little explicit reference to recent literature on perception. (shrink)

This article discusses the theories of perception of Robert Kilwardby and Peter of John Olivi. Our aim is to show how in challenging certain assumptions of medieval Aristotelian theories of perception they drew on Augustine and argued for the active nature of the soul in sense perception. For both Kilwardby and Olivi, the soul is not passive with respect to perceived objects; rather, it causes its own cognitive acts with respect to external objects and thus allows the (...) subject to perceive them. We also show that Kilwardby and Olivi differ substantially regarding where the activity of the soul is directed to and the role of the sensible species in the process, and we demonstrate that there are similarities between their ideas of intentionality and the attention of the soul towards the corporeal world.

A concrete proposal is presented as to how semantics should be naturalized. Rather than attempting to naturalize propositions, they are treated as abstract entities that index concrete cognitive states. In turn the relevant concrete cognitive states are identified via perceptual classifications of worldly states, with the aid of an interactive theory of perception. The approach enables a broadly realist theory of propositions, truth and cognitive states to be preserved, with propositions functioning much as abstract mathematical constructs do in the (...) nonsemantic sciences, but with a much more specific propositional indexing scheme than previous naturalistic proposals were able to achieve.

The problem of academic dishonesty is as old as it is widespread – dating back millennia and perpetrated by the majority of students. Attempts to promote academic integrity, by comparison, are relatively new and rare – stretching back only a few hundred years and implemented by a small fraction of schools and universities. However, the past decade has seen an increase in efforts among universities to promote academic integrity among students, particularly through the use of online courses or tutorials. Previous (...) research has found this type of instruction to be effective in increasing students’ knowledge of academic integrity and reducing their engagement in academic dishonesty. The present study contributes to this literature with a natural experiment on the effects of the Academic Integrity Course (AIC) at The University of Auckland, which became mandatory for all students in 2015. In 2012, a convenience sample of students (n= 780) had been asked to complete a survey on their perceptions of the University’s academic integrity polices and their engagement in several forms of academic dishonesty over the past year. In 2017, the same procedures and survey were used to collect data from second sample of students (n= 608). After establishing measurement invariance across the two samples on all latent factors, analysis of variance revealed mixed support for the studies hypotheses. Unexpectedly, students who completed the AIC (i.e., the 2017 sample) reported: (1) significantly lower (not higher) levels of understanding, support, and effectiveness with respect to the University’s academic integrity policies; (2) statistically equivalent (not higher) levels of peer disapproval of academic misconduct, and; (3) significantly higher (not lower) levels of peer engagement in academic misconduct. However, results related to participants’ personal engagement in academic misconduct offered partial support for hypotheses – those who completed the AIC reported significantly lower rates of engagement on three of the eight behaviors included in the study. The implications and limitations of these findings are discussed as well as possible future directions for research. (shrink)

Why a hermeneutical philosophy of the natural sciences? It is necessary to address the philosophic crisis of realism vs relativism in the natural sciences. This crisis is seen as a part of the cultural crisis that Husserl and Heidegger identified and attributed to the hegemonic role of theoretical and calculative thought in Western societies. The role of theory is addressed using the hermeneutical circle to probe the origin of theoretic meaning in scientific cultural praxes. This is studied in (...) Galileo's discovery of the phases of Venus; the practice of measurement; the different theories and practices of space perception; the historicality and temporality of scientific research communities which ground paradigm change; and the process of discovery. The paper draws particularly from the work of Heidegger. Though envisaging all science and scholarship, the highlighted theme is research in the natural sciences. (shrink)

Consumers are bombarded with labels and claims that are intended to address their concerns about how food products are produced, processed, and regulated. Among those are the natural or all-natural claims and the certified organic label. In this study, two focus groups were conducted to explore consumers’ attitudes toward all-natural and organic pork and to gather their reactions to the USDA organic standards for meat, and the policy for natural claims. Results indicated that participants had positive (...) associations with the terms “organic” and “all-natural” with exceptions regarding the trustworthiness of all-natural claims. Participants perceived the “no” labeling theme (no antibiotics, no hormones, no chemicals, etc.) often coupled with the all-natural label on pork products as identifying potential health and animal welfare risks. In response to the USDA standards and policies for labeling pork products as organic or all-natural, participants expressed confusion and had many unanswered questions. (shrink)
