In Fechner's psychophysics, the 'mental' and the 'physical' were conceived as two phenomenal domains, connected by functional relations, not as two ontologically different realms. We follow the path from Fechner's foundational ideas and Mach's radical programme of a unitary science to later approaches to primary, psychophysically neutral experience (phenomenology, protophysics). We propose an 'integral psychophysics' as a mathematical study of law-like, invariant structures of primary experience. This approach is illustrated by a reinterpretation of psychophysical experiments in terms of (...) perceptual situations involving a constructed apparatus and an instructed subject. The problematic notion of 'measurement of sensation' is thus eliminated: 'sensations' are merely indices for classes of perceptually equivalent configurations (states of the apparatus) specified by the instruction. The locus of the measured is in the inter-subjectively shared, communicable world—not inside the subject's mind. Finally we discuss the role of integral psychophysics as a scientia prima , logically and methodically preceding physics and psychology. (shrink)

The Sufi tradition remains one of the most mysterious and least understood systems of self-realization. This book demystifies the practice of the sohbet—an ad hoc discourse—as the central instructional tool in the globally influential Naqshbandi-Haqqani Order. -/- It approaches the practice using categories of improvised music to establish a framework for analyzation. Its ritualized formal structure, illustrated via selected talks of Shaykh Nazim Adil al-Haqqani, discloses the underlying—and assumingly primary—function to provoke prolonged states of raised awareness in listeners and condition (...) their sympathetic nervous system. -/- In an extensive discussion based on several years of field research in Cyprus, the book relates this intention to similar practices in other traditional knowledge systems by proposing psychophysical interpretations based on psychology, biochemistry, neuroscience, or quantum physics. It will appeal to scholars and students of Sufism, Islamic studies, and comparative religion, as well as those interested in performance studies and improvised music, interpersonal communication, and education.

This chapter provides an overview of the phenomenology of size perception and the use of instructions to tease apart phenomenal and cognitive aspects. It develops his own recent proposals concerning the geometry of visual space. The chapter proposes that visual space is contracted along the lines of sight. This contraction would explain the apparent convergence of railway tracks, but without invoking a “proximal mode” experience. Parallel railway tracks receding into the distance project converging lines onto the retinas. A true (...) proximal mode representation would show these lines converging as if in a vertical plane. But we experience them as converging while also receding in depth along the ground. The chapter suggests that this calls for a third geometry of visual space, intermediate between a linear perspective projection and full phenomenal constancy. The chapter attributes reports of full constancy to cognitive factors. size perception, visual space, geometry, lines of sight, proximal mode, phenomenal constancy. (shrink)

The term “perceptual constancy” was used by the Gestalt theorists in the early part of the twentieth century (e.g., Koffka 1935, 34, 90) to refer to the tendency of perception to remain invariant over changes of viewing distance, viewing angle, and conditions of illumination. This tendency toward constancy is remarkable: every change in the viewing distance, position, and illumination is necessarily accompanied by a change in the local proximal (retinal) stimulation, and yet perception remains relatively stable. The tendency toward perceptual (...) constancy encouraged the Gestalt theorists to look beyond local proximal stimulation in grounding their theories of perception. In the ensuing decades, much has been learned about the constancies. Evidence for this assertion may be found in the contributions to the current volume as well as in earlier volumes (e.g., Epstein 1977; Walsh and Kulikowsky 1998). These advances notwithstanding, significant questions remain open. Our aim here is to note some advances and specify some open questions. (shrink)

Some experiments in perceptual psychology measure perceivers’ phenomenal experiences of objects versus their cognitive assessments of object properties. Analyzing such experiments, this article responds to Pizlo’s claim that much work on shape constancy before 1985 confused problems of shape ambiguity with problems of shape constancy. Pizlo fails to grasp the logic of experimental designs directed toward phenomenal aspects of shape constancy. In the domain of size perception, Granrud’s studies of size constancy in children and adults distinguish phenomenal from cognitive factors.

Colour constancy refers to the ability to extract information about surface colours independently of illumination conditions. A ripe strawberry, for example, appears the same red when viewed under a blue sky or a reddish sunset. Since Land's pioneering work, discussion has centred on the issue whether colour constancy is achieved primarily in the retina or visual cortex. Recently, the debate has shifted to a consideration of the constraints imposed by various psychophysical tasks and instructions. Humans can judge illuminant colour, (...) reflected-light colour, surface colour, and the relationship between surface colours within a scene. Such observations suggest that colour constancy may not be a unitary phenomenon, and that its different aspects may be mediated at different levels in the visual system. Several questions therefore arise: are the tasks of surface estimation and illuminant estimation complementary, insofar as good performance in one implies poor performance in the other? How does retinal adaptation alter performance? Is colour vision tuned to the statistical composition of natural surfaces and illuminants? What role does colour-opponent processing in retina and cortex play in colour constancy? These and related questions are explored here in order to better understand what we mean when we ask: "Why do strawberries look red?". (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 20 (2000) 217-229 [Access article in PDF] Christian Insight Meditation: A Test Case on Interreligious Spirituality Springs SteeleUniversity of Scranton, PennsylvaniaIn Joseph Cardinal Ratzinger's 1989 "Letter to the Bishops of the Catholic Church on Some Aspects of Christian Meditation," there is this significant caveat to Catholics: With the present diffusion of eastern methods of meditation in the Christian world and in ecclesial communities, we find ourselves faced (...) with a pointed renewal of an attempt, which is not free from dangers and errors, to fuse Christian meditation with that which is non-Christian (author's emphasis). Proposals in this direction are numerous and radical to a greater or lesser extent. Some use eastern methods solely as a psychophysical preparation for a truly Christian contemplation; others go further and, using different techniques, try to generate spiritual experiences similar to those described in the writings of certain Christian mystics. Still others do not hesitate to place that absolute without image or concepts, which is proper to Buddhist theory, on the same level as the majesty of God revealed in Christ, which towers above finite reality.... These and similar proposals to harmonize Christian meditation with eastern techniques need to have their contents and methods ever subjected to a thorough-going examination so as to avoid the danger of falling into syncretism. 1Two years before Cardinal Ratzinger's letter, Mary Jo Meadow and Kevin Culligan co-authored an analysis of what they saw as remarkable similarities between the spirituality of the Catholic Carmelite John of the Cross and the Theravadan Buddhist vipassana (or "insight") tradition. 2 They went on, with the help of Daniel Chowning, to develop a spiritual practice that seeks to assimilate traditional Buddhist vipassana meditation into the spirituality of John of the Cross. The impetus was to supplement John's rather general instructions on method with the very detailed methodological program of Theravadan insight practice. 3They have designated this approach "Christian Insight Meditation" and maintain that the Buddhist vipassana practice which is its basis can be assimilated to the spirituality of John because, "... although it originates in Theravadan Buddhism, insight meditation itself does not demand belief in the tenets of Buddhist religion." 4 In fact: [End Page 217] We need not agree with any belief items or be willing to call on any supernatural beings to do the practice. This makes the practice available to everyone without any conflict with whatever religious loyalties they have. This practice is simply a way to apply fine-grained, continuous awareness to all of our experiences of mind and body. Although it is this simple, it leads us to the highest stages of spiritual unfoldment as the major spiritual traditions, including John of the Cross, see them. 5The claim is that vipassana meditation is a neutral (i.e., non-tradition-dependent) practice--simply training in the mindful, equanimous observation of breath, body sensations, mental contents, and movements of the will--which, while not requiring acceptance of the theological or metaphysical tenets of any "major spiritual tradition," leads to the presumed identical ultimate goal of each.This claim is simply asserted by the authors, without positive argument or support. While understandable in a non-academic text such as theirs, there are underlying issues connected with the claim that should be addressed. The first is tradition neutrality. The actual method the authors propose did in fact originate and was developed in the Theravadan Buddhist tradition. It presumes the practice of specific moral principles, the development of concentrative ability in a systematic fashion, and training of attention to highly specific perceptual experiences, all of which culminate in an ultimate state or experience designated nibbana in Pali, and Nirvana in Sanskrit. The authors initially present this spiritual practice in the original conceptual framework of Theravadan Buddhism and then "translate" it into the language of Christianity and John of the Cross. Thus instruction in Christian Insight Meditation is functionally training in Theravadan Buddhist vipassana meditation. As such, the practice is organically rooted in the perceptual or cognitive set 6 of Theravadan vipassana practice. In that sense... (shrink)

Besides the application of the notion of complementarity to psychological and physical descriptions of the individual, this paper explores the possibility of defining complementary observables in the same phenomenal domain. Complementary emotional observables are defined from experimental data on experienced emotions reported by subjects who have been prepared in a state of induced emotion. Complementary physiological observables are defined in correspondence with conjugate, physiological quantities that can be measured. -/- Keywords: Complementarity, Psychophysics, Emotional observables, Induced emotion, Physiological observables, Conjugate (...) physiological quantities.

An experiment was conducted to test the effectiveness of brief instruction in information structuring (i.e., representing and integrating information) for improving the coherence of probability judgments and binary choices among intelligence analysts. Forty-three analysts were presented with comparable sets of Bayesian judgment problems before and immediately after instruction. After instruction, analysts’ probability judgments were more coherent (i.e., more additive and compliant with Bayes theorem). Instruction also improved the coherence of binary choices regarding category membership: after instruction, subjects were more likely (...) to invariably choose the category to which they assigned the higher probability of a target’s membership. The research provides a rare example of evidence-based validation of effectiveness in instruction to improve the statistical assessment skills of intelligence analysts. Such instruction could also be used to improve the assessment quality of other types of experts who are required to integrate statistical information or make probabilistic assessments. (shrink)

How can a course on engineering ethics affect an undergraduate student’s feelings of responsibility about moral problems? In this study, three groups of students were interviewed: six students who had completed a specific course on engineering ethics, six who had registered for the course but had not yet started it, and six who had not taken or registered for the course. Students were asked what they would do as the central character, an engineer, in each of two short cases that (...) posed moral problems. For each case, the role of the engineer was successively changed and the student was asked how each change altered his or her decisions about the case. Students who had completed the ethics course considered more options before making a decision, and they responded consistently despite changes in the cases. For both cases, even when they were not directly involved, they were more likely to feel responsible and take corrective action. Students who were less successful in the ethics course gave answers similar to students who had not taken the course. This latter group of students seemed to have weaker feelings of responsibility: they would say that a problem was “not my business.” It appears that instruction in ethics can increase awareness of responsibility, knowledge about how to handle a difficult situation, and confidence in taking action.

This article proposes an account of color constancy based on an examination of the relevant scientific literature. Differences in experimental settings and task instructions that lead to variation in subject performance are given particular attention. Based on the evidence discussed, the core of the proposal made is that there are two different forms of color constancy, one phenomenal and the other projective. This follows the hypothesis of Reeves et al. (Perception & Psychophysics 70:219–228, 2008). Unlike Reeves et al. (...) (Perception & Psychophysics 70:219–228, 2008), it is argued that projective color constancy is crucially dependent upon phenomenal color constancy and certain aspects of scene perception. Additionally, it is hypothesized that capacities that support projective color constancy have an important role to play in facilitating our ability to quickly recognize scenes with diagnostic chromatic properties independently of assignments of colors to object surfaces.

This study takes an interest in instructions and instructed actions in the context of manual skills. The analysis focuses on a video recorded episode where a teacher demonstrates how to crochet chain stitches, requests a group of students to reproduce her actions, and then repeatedly corrects the attempts of one of the students. The initial request, and the students’ responses to it, could be seen as preliminary to the series of corrective sequences that come next: the request and the (...) following attempts make it possible for the teacher to launch instructional sequences specifically designed and addressed to the students who need further guidance. In the interaction between the teacher and the novice student, the reasoned character of the instructed actions is not explained so much as installed and tuned. The materiality of the project makes it possible for the two parties to methodically and meticulously adjust their actions in accordance with each other, and towards the gradual realization of the aimed-for results. In connection to this, a number of issues pertaining to the reproducibility and recognizability of manual skills are raised: how instructions-in-interaction orient towards the progression of the skill rather than the interaction itself; how attempts by and mistakes of the instructed party provide grounds for further instruction; and, consequently, how instructions in the form of corrections build on the instructor’s continuous assessments of the instructed actions.

This article deals with surgical practice as it is locally organized within the course of the operation; it focuses on the way in which surgical action shaping the body for the local purposes of the operation is organized in a timely, situated, interactive manner. In order to do that, I offer a systematic analysis of the instructions addressed by a chief surgeon to his assistant in the form of directives during a surgical operation, as well as of instructed actions (...) of the assistant following the directives of the surgeon. In this way, I aim to show how surgery is a methodic collaborative achievement, relying on finely tuned coordination between staff members. More generally, the article sketches a systematic and detailed analysis of instructions as situated accomplishments in time, and of instructed action as resulting from an embodied and indexical understanding of directives and requests as they are produced in time and in context.

While much emphasis is placed on the need to improve critical thinking (CT) among college students (Abrami, Bernard, Borokhovski, Wade, Surkes, Tamim, & Zhang, 2008, p. 1102), few studies describe precise methodologies for doing so (Behar-Horenstein & Niu, 2011, p. 36) and even fewer identify improvements in CT dispositions as a desired course outcome (Perkins, Tishman, Ritchhart, Donis, & Andrade, 2000, p. 288). This study attempts to fill a gap in the studies of CT methodologies aimed at improving CT dispositions. (...) In this study, 78 community college students enrolled in a CT course that emphasized targeted CT interventional strategies. The students took the California Critical Thinking Dispositions Inventory (CCTDI) as a pre-test and as a post-test. Results indicate that the targeted instruction significantly influenced overall scores, as well as four of the seven subscale categories. (shrink)

This article presents findings from a series of research studies designed to identify classroom teaching practices that can enhance moral reasoning of undergraduate students in business foundational courses. The research, conducted over five semesters at a Midwestern university, resulted in the development of teaching methods and materials that can, when properly sequenced and integrated into undergraduate business courses, increase levels of student moral reasoning as measured by the revised version of the Defining Issues Test (DIT-2). Findings in this research demonstrate (...) that faculty members who are not specialists in business ethics can effect positive increases in student moral reasoning in non-ethics business courses. However, significant time and effort must be invested in case-based moral decision making, and grade incentives for students to engage the use of an ethical decision-making framework are required.

This paper considers the issue of computer-assisted composition in formal music education settings from the perspective of critical theory. The author examines the case of MIDI-based software applications and suggests that the greatest danger from the standpoint of ideology critique is not the potential for circumventing a traditional understanding of theoretical knowledge and notation when composing. Instead, it is false subjectivity, or the potential belief that what one creates is free from the mediation of tacit musical conventions and the ideological (...) biases of the technology itself. Developing a framework for critique that is partially based on the writings of Theodor Adorno and draws on a dialectical conception of composing, the author applies this framework to the issue of MIDI-based composition in order to make this case.

SummaryThe development of universities and technical schools in nineteenth century Switzerland is commonly assumed to be similar to the development of comparable schools in Germany. To a large extent this is correct, but there are subtle differences in the founding and organization of Swiss institutions that are reflective of the Swiss national and local cantonal contexts. In the case of Zürich, the specific local political and financial conditions underlying the formation of the University of Zürich, the Zürich Cantonal School and (...) the Swiss Federal Polytechnic resulted in a complex set of dual appointments and shared facilities that were absent at comparable chemical laboratories at German universities. This essay outlines the origins of these complex relationships under Carl Löwig and Georg Städeler and follows in more detail the complex career path of Johannes Wislicenus in Zürich from his appointment as Privatdozent in 1860 to his appointment as Director of the Polytechnic in 1871. Wislicenus’ career path illustrates the institutional context of chemistry in Zürich and shows how this context, including the roles of cantonal and federal support, and the physical constraints created by shared laboratory facilities, shaped chemical research and instruction in Zürich.

Business school faculty have begun to increase ethics instruction, but very little has been done to assess the effectiveness of this instruction. Curricula-wide studies present conflicting results of the effect of ethics integration into the business curricula. Several studies suggest that courses like business ethics and business and society might have an effect on the ethical awareness or ethical reasoning of business students. A belief of many individuals interested in business ethics is that students must be exposed to ethical awareness (...) and ethical reasoning in business ethics and business and society-type courses and this should be supplemented by discussions of these topics in various business courses such as Accounting, Finance, Marketing, and others.This study reports the results of integrating a unit of business ethics into eleven accounting classes at two universities. An approach for measuring the effect of ethics integration into accounting and other business courses is suggested, and an assessment is made of the impact of ethics integration on students in accounting classes. Results indicate that the principles on which students rely when making moral decisions were affected by ethics integration. After ethics integration, students relied more heavily on the disclosure rule, the golden rule, and the professional ethic. (shrink)

The facilities provided for practical teaching at the Ecole Polytechnique, at the time of its foundation and during the Napoleonic period, have been the subject for much research and conjecture. Documents are discussed and presented which throw light on the actual situation, the number of laboratories, their equipment and apparatus, and the amount of practical instruction provided for the students.
