Navigating to goal locations in a known environment (wayfinding) can be accomplished by different strategies, notably by taking habitual, well-learned routes (response strategy) or by inferring novel paths, such as shortcuts, from spatial knowledge of the environment's layout (place strategy). Human and animal neuroscience studies reveal that these strategies reflect different brain systems, with response strategies relying more on activation of the striatum and place strategies associated with activation of the hippocampus. In addition to individual differences in strategy, recent behavioral (...) studies show sex differences such that men use place strategies more than women, and age differences such that older adults use more response strategies than younger adults. This paper takes a comprehensive multilevel approach to understanding these differences, characterizing wayfinding as a complex information processing task. This analysis reveals factors that affect navigation strategy, including availability of the relevant type of environmental knowledge, momentary access to this knowledge, trade-offs between physical and mental effort in different navigation contexts, and risk taking. We consider how strategies are influenced by the computational demands of a navigation task and by factors that affect the neural circuits underlying navigation. We also discuss limitations of laboratory studies to date and outline priorities for future research, including relating wayfinding strategies to independent measures of spatial knowledge, and studying wayfinding strategies in naturalistic environments.

Three experiments examined the effects of interactive visualizations and spatial abilities on a task requiring participants to infer and draw cross sections of a three‐dimensional (3D) object. The experiments manipulated whether participants could interactively control a virtual 3D visualization of the object while performing the task, and compared participants who were allowed interactive control of the visualization to those who were not allowed control. In Experiment 1, interactivity produced better performance than passive viewing, but the advantage of interactivity disappeared in (...) Experiment 2 when visual input for the two conditions in a yoked design was equalized. In Experiments 2 and 3, differences in how interactive participants manipulated the visualization were large and related to performance. In Experiment 3, non‐interactive participants who watched optimal movements of the display performed as well as interactive participants who manipulated the visualization effectively and better than interactive participants who manipulated the visualization ineffectively. Spatial ability made an independent contribution to performance on the spatial reasoning task, but did not predict patterns of interactive behavior. These experiments indicate that providing participants with active control of a computer visualization does not necessarily enhance task performance, whereas seeing the most task‐relevant information does, and this is true regardless of whether the task‐relevant information is obtained actively or passively.

This issue assesses how human spatial navigation differs: within individuals across short‐term variations in mood or stress, and between individuals across variations in age, gender, education, culture, and physical environment.

Three studies were conducted to examine the relation of spatial visualization to solving kinematics problems that involved either predicting the two‐dimensional motion of an object, translating from one frame of reference to another, or interpreting kinematics graphs. In Study 1, 60 physics‐naíve students were administered kinematics problems and spatial visualization ability tests. In Study 2, 17 (8 high‐ and 9 low‐spatial ability) additional students completed think‐aloud protocols while they solved the kinematics problems. In Study 3, the eye movements of fifteen (...) (9 high‐ and 6 low‐spatial ability) students were recorded while the students solved kinematics problems. In contrast to high‐spatial students, most low‐spatial students did not combine two motion vectors, were unable to switch frames of reference, and tended to interpret graphs literally. The results of the study suggest an important relationship between spatial visualization ability and solving kinematics problems with multiple spatial parameters. (shrink)

Individuals differ greatly in their ability to learn and navigate through environments. One potential source of this variation is “directional sense” or the ability to identify, maintain, and compare allocentric headings. Allocentric headings are facing directions that are fixed to the external environment, such as cardinal directions. Measures of the ability to identify and compare allocentric headings, using photographs of familiar environments, have shown significant individual and strategy differences; however, the neural basis of these differences is unclear. Forty-five college students, (...) who were highly familiar with a campus environment and ranged in self-reported sense-of-direction, underwent fMRI scans while they completed the Relative Heading task, in which they had to indicate the direction of a series of photographs of recognizable campus buildings (i.e., “target headings”) with respect to initial “orienting headings”. Large individual differences were found in accuracy and correct decision latencies, with gender, self-reported sense-of-direction, and familiarity with campus buildings all predicting task performance. Using linear mixed models, the directional relationships between headings and the experiment location also impacted performance. Structural scans revealed that lateral orbitofrontal and superior parietal volume were related to task accuracy and decision latency, respectively. Bilateral hippocampus and right presubiculum volume were related to self-reported sense-of-direction. Meanwhile, functional results revealed clusters within the superior parietal lobule, supramarginal gyrus, superior frontal gyrus, lateral orbitofrontal cortex, and caudate among others in which the intensity of activation matched the linear magnitude of the difference between the orienting and target headings. While the retrosplenial cortex and hippocampus have previously been implicated in the coding of allocentric headings, this work revealed that comparing those headings additionally involved frontal and parietal regions. These results provide insights into the neural bases of the variation within human orientation abilities, and ultimately, human navigation. (shrink)

The landscape of graduate science education is changing as efforts to diversify the professoriate have increased because academic faculty jobs at universities have grown scarce and more competitive. With this context as a backdrop, the present research examines the perceptions and career goals of advisors and advisees through surveys of PhD students and faculty mentors in science, technology, engineering, and math disciplines. Study 1 examined actual preferences and career goals of PhD students among three options: research careers, teaching careers, and (...) non-academic careers in industry, and compared the actual preferences of students with what they perceived as being the normative preferences of faculty. Overall, students had mixed preferences but perceived that their advisors had a strong normative preference for research careers for them. Moreover, students who ranked research positions as most desirable felt the most belonging in their academic departments. Further analyses revealed no differences in career preferences as a function of underrepresented minority student status or first-generation status, but URM and FG students felt less belonging in their academic departments. Study 2 examined faculty preferences for different careers for their advisees, both in general and for current students in particular. While faculty advisors preferred students to go into research in general, when focusing on specific students, they saw their preferences as being closely aligned with the career preference of each PhD student. Faculty advisors did not perceive any difference in belonging between their students as a function of their URM status. Discrepancies between student and faculty perceptions may occur, in part, because faculty and students do not engage in sufficient discussions about the wider range of career options beyond academic research. Supporting this possibility, PhD students and faculty advisors reported feeling more comfortable discussing research careers with each other than either non-academic industry positions or teaching positions. Discussion centers on the implications of these findings for interpersonal and institutional efforts to foster diversity in the professoriate and to create open communication about career development.

Some commentators have condemned Kant’s moral project from a feminist perspective based on Kant’s apparently dim view of women as being innately morally deficient. Here I will argue that although his remarks concerning women are unsettling at first glance, a more detailed and closer examination shows that Kant’s view of women is actually far more complex and less unsettling than that attributed to him by various feminist critics. My argument, then, undercuts the justification for the severe feminist critique of Kant’s (...) moral project. (shrink)

Classical logic has proved inadequate in various areas of computer science, artificial intelligence, mathematics, philosopy and linguistics. This is an introduction to extensions of first-order logic, based on the principle that many-sorted logic (MSL) provides a unifying framework in which to place, for example, second-order logic, type theory, modal and dynamic logics and MSL itself. The aim is two fold: only one theorem-prover is needed; proofs of the metaproperties of the different existing calculi can be avoided by borrowing them from (...) MSL. To make the book accessible to readers from different disciplines, whilst maintaining precision, the author has supplied detailed step-by-step proofs, avoiding difficult arguments, and continually motivating the material with examples. Consequently this can be used as a reference, for self-teaching or for first-year graduate courses. (shrink)

This article considers the two major biographies of sexologist Magnus Hirschfeld, MD (1868—1935), an early campaigner for ‘gay rights’ avant la lettre. Like him, his first biographer Charlotte Wolff (1897—1986) was a Jewish doctor who lived and worked in Weimar Republic Berlin and fled Germany when the Nazi regime came to power. When researching Hirschfeld’s biography (published in English in 1986) Wolff met a librarian and gay activist, Manfred Herzer, who would eventually be a cofounder of the Gay Museum in (...) Berlin and publish (in German, in 1992) the other major Hirschfeld biography currently available. Using, inter alia, the correspondence between Wolff and Herzer, the article aims to explore and interrogate the boundaries and possibilities of ‘biography’ as a form of ‘doing history’. (shrink)

Noise permeates our highly mediated and globalised cultures. Noise as art, music, cultural or digital practice is a way of intervening so that it can be harnessed for an aesthetic expression not caught within mainstream styles or distribution. This wide-ranging book examines the concept and practices of noise, treating noise not merely as a sonic phenomenon but as an essential component of all communication and information systems. The book opens with ideas of what noise is, and then works through ideas (...) of how noise works in contemporary media, to conclude by showing potentials within noise for a continuing cultural renovation through experimentation. Considered in this way, noise is seen as an essential yet excluded element of contemporary culture that demands a rigorous engagement. Reverberations brings together a range of perspectives, case studies, critiques and suggestions as to how noise can mobilize thought and cultural activity through a heightening of critical creativity.Written by a strong, international line-up of scholars and artists, Reverberations looks to energize this field of study and initiate debates for years to come.

One of the clearest signs that Psychology has impacted popular culture is the public’s familiarity with the Rorschach ink-blot test. An excellent example of the Rorschach in popular culture can be found in Watchmen, the comic/graphic novel written by Alan Moore and Dave Gibbons. In the mid-20th century Psychology had an especially contentious relationship with comics; some psychologists were very anxious about the impact comics had on young people, whereas others wrote comics to subvert dominant norms about gender and sexuality. (...) Yet historians of Psychology have had almost nothing to say about this popular and critically acclaimed novel. We read Watchmen here for its narratives that most concern the history of Psychology. We focus on such themes as anti-psychiatry, sexual violence, homophobia, lesbian erasure and social psychological research on bystander intervention. We argue it is possible to align Psychology and comics more closely despite their sometimes contentious history. In doing so we demonstrate the active role of the public in the history of the Rorschach, and the public engagement of Psychology via comics, and also reveal what is possible when historians consider comics within their histories.

There has been growing enthusiasm amongst those who undertake research with children, for the development of participatory and visual research methods. The greater availability and affordability of digital technology has meant that there has been greater scope for digital technology to support participatory research methods, or augment more traditional qualitative research methods. While digital technology provides new opportunities for qualitative researchers, they also come with a series of challenges – some of which have been grappled with by those using more (...) traditional research methods but also some which are new. Our study was undertaken in Victoria, Australia, and used a combination of interviews, focus groups and digital storytelling to bring together two strands of work which have historically occurred separately: work with children experiencing domestic violence and programs for men who use domestic violence. While digital storytelling proved to be an effective method of engaging children and young people in the research, a range of challenging ethical issues emerged. Some of these issues were considered as part of the formal ‘procedural ethics’ process, but additional and more challenging issues relating to anonymity and the complex safety considerations of using of the children’s digital stories within programs for men who use violence and dissemination emerged in practice. It is hoped that sharing our experiences and decision-making will contribute to the knowledge base for others considering engaging in sensitive research using digital technology. (shrink)

In the Philippines, all transplant centers are mandated by the Department of Health (DOH) to have a Hospital Transplant Ethics Committee (HTEC) to ensure that donations are altruistic, voluntary and free of coercion/commercial transactions. This study was undertaken primarily to describe the organizational and functional profile of existing HTECs and identify areas for improvement. This is a descriptive cross‐sectional study. There was variation in their logistical arrangements (support from hospital, filing systems, office spaces), operations (length and frequency of meetings, number (...) of referrals) and membership (composition, qualifications, occupation, training). The approval rate for donor‐recipient pairs is high with the majority of cases made by living non‐related donors. Appropriate reasons were cited for rejection. The perception of HTECs is that they are competent and confident in their decision‐making. However, there is a need to standardize HTEC composition, provide operating procedures and additional training which can be done by the DOH. (shrink)

I argue that a dilemma arises for naturalistic philosophers of mind in the naturalised semantics tradition. Giving a naturalistic account of the mind is a pressing problem. Brentano’s Thesis — that a state is mental if, and only if, that state has underived representational content — provides an attractive route to naturalising the mental. If true, Brentano’s Thesis means that naturalising representation is sufficient for naturalising the mental. But a naturalist who accepts Brentano’s Thesis thus commits to an eliminativism about (...) the category of the mental. This is because naturalistic theories of representation are reductive, and so over-generalise by applying to patently non-mental states. According to these theories, it has been argued, phenomena like tree rings and saliva come out as representational. Only proposing further Naturalistic conditions on representation could avoid the eliminativist conclusion. But this shows that Naturalists have made only limited progress towards naturalising the mental. And if a Naturalist rejects Brentano’s Thesis, then she gives up on a clear link between representation and mentality. Hence, it is incumbent on the Naturalist to propose another, naturalistically acceptable, mark of the mental. This, again, shows that Naturalists have made only limited progress on the issue of naturalising the mental.Keywords: Intentionality, representation, physicalism, eliminativism, Brentano, materialism, naturalism.

Professionals and researchers in sociology, communication, and anthropology will especially appreciate this auspicious new book. (shrink)

How is hope to be found amid the ethical and political dilemmas of modern life? Writer and philosopher Mary Zournazi brought her questions to some of the most thoughtful intellectuals at work today. She discusses "joyful revolt" with Julia Kristeva, the idea of "the rest of the world" with Gayatri Spivak, the "art of living" with Michel Serres, the "carnival of the senses" with Michael Taussig, the relation of hope to passion and to politics with Chantal Mouffe and Ernesto (...) Laclau. A dozen stimulating minds weigh in with their visions of a better social and political order. The result is a collaboration - of writing, of thinking, and of politics - that demonstrates more clearly than any single-authored project could how ideas encountering one another can produce the vision needed for social change.

This study of morphological overabundance focuses on the (non-)synonymy of parallel forms in Estonian illative case (‘into’) and the type of entrenchment behind it. We focus on the lexical level, testing whether the form preferred for a lexeme depends on semantic or morphophonological factors, or both. Using multifactorial regression analyses, we compare three corpus datasets: lexemes biased toward long forms, those biased toward short forms and lexemes with balanced form distribution. This is the first study to investigate realised overabundance in (...) this way, and to include inflection class membership in the model, enabling us to test whether declension class subsumes the morphophonological factors found to affect form preference in previous studies. The analysis shows that cell token frequency and inflection class are significant predictors of form preference, while the lexical-semantic features included in the study do not affect formative choice, highlighting the role of cell entrenchment instead of formative entrenchment in guiding form use. In conclusion, the study highlights the important role of inflection class (morphophonology) in the general shaping of form usage patterns in parallel forms and the weak role of semantic factors on the lexical level.

Plato famously promised to complement the Sophist and the Statesman with another work on a third sort of expert, the philosopher--but we do not have this final dialogue. Mary Louise Gill argues that Plato promised the Philosopher, but did not write it, in order to stimulate his audience and encourage his readers to work out, for themselves, the portrait it would have contained. The Sophist and Statesman are themselves members of a larger series starting with the Theaetetus, Plato's investigation (...) of knowledge, and the whole series relies on the Parmenides, the second part of which presents a philosophical exercise, introduced as the first step in a larger philosophical program. Gill contends that the dialogues leading up to the missing Philosopher, though they reach some substantive conclusions, are philosophical exercises of various sorts designed to train students in dialectic, the philosopher's method; and that a second version of the Parmenides exercise, closely patterned on it, spans parts of the Theaetetus and Sophist and brings the philosopher into view. This is the exercise about being, the subject-matter studied by Plato's philosopher. Plato hides the pieces of the puzzle and its solution in plain sight, forcing his students (and modern readers) to dig out the pieces and reconstruct the project. Gill reveals how, in finding the philosopher through the exercise, the student becomes a philosopher by mastering his methods. She shows that the target of Plato's exercise is internally related to its pedagogical purpose. (shrink)

"Charming, interesting, thought-provoking and a great read." Rosalind Hursthouse The daughter of a pacifist rector who answered "No!" when his congregation asked him "Is everything in the bible true?", perhaps Mary Midgley was destined to become a philosopher. Yet few would have thought this inquisitive, untidy, nature-loving child would become "one of the sharpest critical pens in the west." This is her remarkable story. Probably the only philosopher to have been in Vienna on the eve of its invasion by (...) Nazi Germany in 1938 and dance in Trafalgar Square on VE day seven year later, she studied philosophy at Oxford in the same year as Iris Murdoch, Elizabeth Anscombe and Philippa Foot, all of whom became close friends. Midgley tells us in vivid and humorous fashion how they cut a swathe through the arid landscape of 1950s British philosophy, writing and arguing - often with each other - about the grand themes of character, beauty and the meaning of rudeness while the spectral figure of Ludwig Wittgenstein hovered in the background. She also charts the highs and lows of philosophy and academia in Britain. On joining the Reading philosophy department on £400 a year in 1949, she doubled its staff complement. But her many years at Newcastle University - where Mike Brearley, who later captained England at cricket, also used to teach - were rewarded with the closure of the philosophy department in the 1980s. The mother of three children, her journey is also one of a woman who in the 1950s and 1960s was fighting to combine a professional career with raising a family. In startling contrast to many of the academic stars of her generation, we learn that Midgley nearly became a novelist and started writing philosophy only when in her fifties, suggesting that Minerva's owl really does fly at dusk. Plainly told like her philosophy, this is an elegiac and moving account of friendships found and lost, bitter philosophical battles and of a profound love of teaching all too rarely acknowledged today.

Ethics applications to conduct research with children who have experienced domestic violence will frequently raise a red flag to ethics committees about the potential for risk and re-traumatization. On the other hand, such sensitive research can enable a hidden, marginalized population to have their voices heard. It can deliver findings about children’s lives that can inform otherwise adult-centric research, policy and practice initiatives. The authors highlight ethical concerns and practical solutions using examples from domestic violence, family law and child abuse (...) research with children. Ethical planning is explored according to methodologies, context and whether the violence has been named. Also discussed are consent procedures, confidentiality and the development of protocols for disclosure, distress, safety and risk assessment, which support ethical and safe research with children.

Blanchot took Mallarmé’s “Book” as the paradigm for an artwork that aspired to such excess it could not exist. And yet it partly did, in the form of the poem Un coup de dés jamais n’abolira le hasard. For Blanchot, this ultimate literary work acted as a model for a relentless deconstructing not just of what existed but also of that which did not. His emptying theoretical perspective is ideally suited to analyse the phenomenon that is harsh noise wall music. (...) This type of music aims to be both total and static, an extreme stilling of the music impulse, and even of noise itself. This stilling will of course fail, in the shape of recordings, concerts, recognizable “pieces,” but this failing puts it into the same realm as the Book, as glossed and mobilized by Blanchot, in that it exists but it should not. It cannot happen and yet it unfolds. Rather than failure, then, I argue that this type of noise music is one realization of Blanchot’s thinning, dissipating and disappearing of Mallarmé’s project. This completion, present in these writers and in harsh noise wall, notably in the work of Romain Perrot is not just resemblance but is something that enables a reading, a return completion of Blanchot. This article looks to stage this double reading, a reading that produces nothing. Actually, not even nothing. (shrink)

Rae Langton and Jennifer Hornsby argue that there may be a free-speech argument against pornography, if pornographic speech has the power to illocutionarily silence women: women's locution ‘No!’ that aims to refuse unwanted sex may misfire because pornography creates communicative conditions where the locution does not count as a refusal. Central to this is the view that women's speech lacks uptake, which is necessary for illocutionary acts like that of refusal. Alexander Bird has critiqued this view by arguing that uptake (...) is not necessary for the illocutionary act of refusal. The Hornsby-Langton view, then, is philosophically indefensible. Here I defend the philosophical cogency of the Hornsby-Langton approach. (shrink)
