Among psychologists and vision scientists,binocular rivalry has enjoyed sustainedinterest for decades dating back to the 19thcentury. In recent years, however, rivalry''saudience has expanded to includeneuroscientists who envision rivalry as a tool for exploring the neural concomitants ofconscious visual awareness and perceptualorganization. For rivalry''s potential to berealized, workers using this tool need toknow details of this fascinating phenomenon,and providing those details is the purpose ofthis article. After placing rivalry in ahistorical context, I summarize major findingsconcerning the spatial characteristics and thetemporal dynamics (...) of rivalry, discuss two majortheoretical accounts of rivalry ( eye vs stimulus rivalry) and speculate on possibleneural concomitants of binocular rivalry.

Sociopolitical attitudes are often the root cause of conflicts between individuals, groups, and even nations, but little is known about the origin of individual differences in sociopolitical orientation. We test a combination of economic and evolutionary ideas about the degree to which the mating market, sex, age, and income affect sociopolitical orientation. We collected data online through Amazon’s Mechanical Turk from 1108 US participants who were between 18 and 60, fluent in English, and single. While ostensibly testing a new online (...) dating website, participants created an online dating profile and described people they would like to date. We manipulated the participants’ popularity in the mating market and the size of the market and then measured participants’ sociopolitical attitudes. The sociopolitical attitudes were reduced to five dimensions via Principal Components Analysis. Both manipulations affected attitudes toward wealth redistribution but were largely not significant predictors of the other dimensions. Men reported more unrestricted sociosexual attitudes, and more support for benevolent sexism and traditional family values, than women did, and women supported wealth redistribution more than men did. There was no sex difference in accepting nonconforming behaviors. Younger people and people with lower incomes were more liberal than older people and people with higher incomes, respectively, regardless of sex. Overall, effects were largely not interactive, suggesting that individual differences in sociopolitical orientation may reflect strategic self-interest and be more straightforward than previously predicted.

Numerous social, economic and academic pressures can have a negative impact on representations of biomedical research. We review several of the forces playing an increasingly pernicious role in how health and science information is interpreted, shared and used, drawing discussions towards the role of narrative. In turn, we explore how aspects of narrative are used in different social contexts and communication environments, and present creative responses that may help counter the negative trends. As traditional methods of communication have in many (...) ways failed the public, changes in approach are required, including the creative use of narratives. (shrink)

Skin-transmitted pathogens have threatened humans since ancient times. We investigated whether skin-transmitted pathogens were a subclass of disgust stimuli that evoked an emotional response that was related to, but distinct from, disgust and fear. We labelled this response “the heebie jeebies”. In Study 1, coding of 76 participants’ experiences of disgust, fear, and the heebie jeebies showed that the heebie jeebies was elicited by unique stimuli which produced skin-crawling sensations and an urge to protect the skin. In Experiment 2,350 participants’ (...) responses to skin-transmitted pathogen, fear-inducing, and disgust-inducing vignettes showed that the vignettes elicited sensations and urges which loaded onto heebie jeebies, fear, and disgust factors, respectively. Experiment 3 largely replicated findings from Experiment 2 using video stimuli. Results are consistent with the notion that skin-transmitted pathogens are a subclass of disgust stimuli which motivate behaviours that are functionally consistent with disgust yet qualitatively distinct.

Firearm injury in the United States is a public health crisis in which physicians are uniquely situated to intervene. However, their ability to mitigate harm is limited by a complex array of laws and regulations that shape their role in firearm injury prevention. This piece uses four clinical scenarios to illustrate how these laws and regulations impact physician practice, including patient counseling, injury reporting, and the use of court orders and involuntary holds. Unintended consequences on clinical practice of laws intended (...) to reduce firearm injury are also discussed. Lessons drawn from these cases suggest that physicians require more nuanced education on this topic, and that policymakers should consult front-line healthcare providers when designing firearm policies.

A study of Blake's poetry and its use of Kabalistic imagery to depict the fall of man to selfhood and the hope of regeneration through the "sweet science" of imagination.--A. R.

In this source study of the hermetic and prophetic poetry of William Blake, Kathleen Raine adds strength to the theory that it takes a poet to explain one. The present volumes, expanded from the 1962 Mellon Lectures in the Fine Arts, are the result of twenty years' research; in scholarship and in style, they well might serve as a model for all source studies to come. Raine traces Blake's borrowings from Neoplatonism, from alchemy, from classical and hermetic sources, (...) from gnosticism and Christianity. Her development avoids the rigid chronological installment method so often used and moves along lyrically in chapter divisions sometimes source inspired, more often determined by particular characters created by Blake himself. Two very complete indexes, both of Blake's works and of general subjects, allow for immediate reference within the author's rather fluid organization. Mention must be made also of the beautiful plate reproductions which encourage a more integrated appreciation of Blake's two media of expression. Raine communicates the universal nature of visionary poetry, the basic sources of which have not changed significantly throughout the centuries. She thus opens up for the reader the possibility of understanding a whole tradition of the most awesome and most inaccessible literature.--C. M. R. (shrink)

BackgroundPrivate umbilical cord blood banking is a for-profit industry in which parents pay to store blood for potential future use. Governments have noted the tendency for private banks to oversell the potential for cord blood use, especially in relation to speculative cell therapies not yet supported by clinical evidence. We assessed the regulatory landscape governing private cord bank marketing in Canada.Main bodyBecause the problematic marketing of private cord blood banking for future use often relates to speculative future cell therapies that (...) do not exist and are not being advertised for current clinical use, most private blood bank marketing seems to fall outside Health Canada’s regulatory scope. However, this problematic marketing is regulated by the Competition Bureau pursuant to the Competition Act. While representations relating to future hypothetical treatments may not always be subject to the legal requirement for claim substantiation, the law also prohibits individuals and companies from knowingly or recklessly making representations that are “false or misleading in a material respect.” A representation is materially false or misleading when it could “influence a consumer’s behavior or purchasing decisions,” and consumers are likely to be considered to be “credulous and inexperienced” for the purposes of assessing an advertisement’s general impression. Because all of the potential benefit of the banking is derived from the potential future use of the biological material for health interventions directed toward the customers and their relatives, and because we know the best available medical evidence indicates a very low probability of utility in this context, we can say with confidence that some private cord blood banking claims are materially misleading. Moreover, to the extent that medical professionals are involved in private bank interactions with customers or hold ownership stakes in private banks, they are subject to professional codes, standards of practice, and potentially fiduciary obligations that further prohibit misleading marketing.ConclusionsPrivate cord blood bank marketing that advertises hypothetical future treatments can be misleading and may influence consumer behaviour. This marketing may breach existing advertising law. Regulatory bodies should enforce the law in order to help prevent public health and personal financial harm. (shrink)
