The visual world of adults consists of objects at various distances, partly occluding one another, substantial and stable across space and time. The visual world of young infants, in contrast, is often fragmented and unstable, consisting not of coherent objects but rather surfaces that move in unpredictable ways. Evidence from computational modeling and from experiments with human infants highlights three kinds of learning that contribute to infants’ knowledge of the visual world: learning via association, learning via active assembly, and learning (...) via visual-manual exploration. Infants acquire knowledge by observing objects move in and out of sight, forming associations of these different views. In addition, the infant’s own self-produced behavior—oculomotor patterns and manual experience, in particular—is an important means by which infants discover and construct their visual world.

Is it socially responsible to price at a premium, company branded generic pharmaceuticals in emerging economies? Building toward an answer to this question, the study first describes the role of the branded generic sector in the economic success of the global pharmaceutical industry. Second, the concept of “shared value,” i.e., the link between competitive advantage and corporate social responsibility, is introduced and applied to the global pharmaceutical industry’s position on marketing generic pharmaceuticals. Third, an empirical evaluation ascertains whether there is (...) sufficient shared value for this company branded generics pricing strategy to be considered “socially responsible.” Fourth, after concluding there is sufficient shared value, a discussion section offers a public/private framework that will help ensure that safe and effective pharmaceuticals are sold to consumers in developing economies. Lastly, a summary and conclusion section completes the article. (shrink)

Adults and infants display a robust ability to perceive the unity of a center-occluded object when the visible ends of the object undergo common motion (e.g. Kellman, P.J., Spelke, E.S., 1983. Perception of partly occluded objects in infancy. Cognitive Psychology 15, 483±524). Ecologically oriented accounts of this ability focus on the primacy of motion in the perception of segregated objects, but Gestalt theory suggests a broader possibility: observers may perceive object unity by detecting patterns of synchronous change, of which common (...) motion is a special case. We investigated this possibility with observations of adults and 4-month-old infants. Participants viewed a center-occluded object whose visible surfaces were either misaligned or aligned, stationary or moving, and unchanging or synchronously changing in color or bright- ness in various temporal patterns (e.g. ¯ashing). Both alignment and common motion con- tributed to adults' perception of object unity, but synchronous color changes did not. For infants, motion was an important determinant of object unity, but other synchronous changes and edge alignment were not. When a stationary object with aligned edges underwent syn- chronous changes in color or brightness, infants showed high levels of attention to the object, but their perception of its unity appeared to be indeterminate. An inherent preference for fast over slow ¯ash rates, and a novelty preference elicited by a change in rate, both indicated that infants detected the synchronous changes, although they failed to use them as information for object unity. These ®ndings favor ecologically oriented accounts of object perception in which surface motion plays a privileged role. Ó 1999 Elsevier Science B.V. All rights reserved. (shrink)

Exercise psychology encompasses the disciplines of psychiatry, clinical and counseling psychology, health promotion, and the movement sciences. This emerging field involves diverse mental health issues, theories, and general information related to physical activity and exercise. Numerous research investigations across the past 20 years have shown both physical and psychological benefits from physical activity and exercise. Exercise psychology offers many opportunities for growth while positively influencing the mental and physical health of individuals, communities, and society. However, the exercise psychology literature has (...) not addressed ethical issues or dilemmas faced by mental health professionals providing exercise psychology services. This initial discussion of ethical issues in exercise psychology is an important step in continuing to move the field forward. Specifically, this article will address the emergence of exercise psychology and current health behaviors and offer an overview of ethics and ethical issues, education/training and professional competency, cultural and ethnic diversity, multiple-role relationships and conflicts of interest, dependency issues, confidentiality and recording keeping, and advertisement and self-promotion.

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

The late twentieth century has provided both reasons and occasions for reassessing just war theory as an organizing framework for the moral analysis of war. Books by G. Scott Davis, James T. Johnson, and John Kelsay, together with essays by Jeffrey Stout, Charles Butterworth, David Little, Bruce Lawrence, Courtney Campbell, and Tamara Sonn, signal a remarkable shift in war studies as they enlarge the cultural lens through which the interests and forces at play in political violence are identified and (...) evaluated. In his review of the contribution made by these texts, the author focuses on the cohesion of just war theory, the asymmetry between Christian and Islamic attitudes toward holy war, and the need to develop just war theory into a tool adequate to assist in the moral evaluation of violent conflicts within, not just between, nation-states.

The ability to imagine objects undergoing rotation (mental rotation) improves markedly with practice, but an explanation of this plasticity remains controversial. Some researchers propose that practice speeds up the rate of a general-purpose rotation algorithm. Others maintain that performance improvements arise through the adoption of a new cognitive strategy—repeated exposure leads to rapid retrieval from memory of the required response to familiar mental rotation stimuli. In two experiments we provide support for an integrated explanation of practice effects in mental rotation (...) by combining behavioral and EEG measures in a way that provides more rigorous inference than is available from either measure alone. Before practice, participants displayed two well-established signatures of mental rotation: Both response time and EEG negativity increased linearly with rotation angle. After extensive practice with a small set of stimuli, both signatures of mental rotation had all but disappeared. In contrast, after the same amount of practice with a much larger set both signatures remained, even though performance improved markedly. Taken together, these results constitute a reversed association, which cannot arise from variation in a single cause, and so they provide compelling evidence for the existence of two routes to expertise in mental rotation. We also found novel evidence that practice with the large but not the small stimulus set increased the magnitude of an early visual evoked potential, suggesting increased rotation speed is enabled by improved efficiency in extracting three-dimensional information from two-dimensional stimuli.

Rewards are reinforcement mechanisms that organizations use to shape desirable employee behaviors. However, rewards may also have unintended consequences, such as building expectations for receiving extra benefits and weakening employee barriers to unethical acts. This article investigates the dark side of the reward–behavior association, and exploring what is referred to as the reward–theft parity effect (RTPE). The authors hypothesize that receiving rewards induces a corresponding type of theft. In Study 1, survey results (n = 634) show initial support for the (...) RTPE between rewards and same‐category theft, and that perceptions of procedural justice attenuate this association. Study 2 involved a 2 (reward) × 2 (theft opportunity) between‐subjects experimental design (n = 300) and provides further support for the RTPE by revealing greater theft under a reward–theft parity condition than under a reward–theft disparity condition. Study 3 replicates these findings in a field experiment (n = 285) and finds that the RTPE is exacerbated when the reward–behavior task is perceived as unjust. Collectively, these findings provide new theoretical insights while also giving managers a more complete understanding of the dark side of behavioral reinforcement mechanisms. (shrink)

A premise of Corballis's theory is that speech arose when vocalization co-opted existing gestural functions in the left ventral premotor cortex. Yet, visuomotor functions in this region remain largely unchanged between humans and macaques and have no discernible connection to gestural communication. This functional continuity suggests that language production is not the result of modifying existing motor functions in this region.

The Handbook of the Study of Play brings together, in two volumes, thinkers whose diverse interests at the leading edge of scholarship and practice define the current field. Because play is an activity that humans have shared across time, place, and culture, and in their personal developmental timelines - and because this behavior stretches deep into the evolutionary past - no single discipline can lay claim to exclusive rights to study the subject. Thus, this handbook features the thinking of evolutionary (...) psychologists; ethologists and biologists; neuroscientists; developmental psychologists; psychotherapists and play therapists; historians; sociologists and anthropologists; cultural psychologists; philosophers; theorists of music, performance, and dance; specialists in learning and language acquisition; and playground designers. Together, but out of their varied understandings, the incisive contributions to The Handbook of the Study of Play take on vital questions of educational policy, literacy, fitness, the role of play in brain development, spotaneity and pleasure, well-being and happiness, fairness, and the fuller realization of the self. These volumes also comprise an intellectual history, offering retrospective looks at the great thinkers who have made possible the modern study of play. -- from back cover. (shrink)

Glover suggests that representational systems for planning versus control are mapped exclusively to the inferior (IPL) versus superior (SPL) parietal lobules respectively. Yet, there is ample evidence that the IPL and SPL both contribute to action planning and control. Alternatively, I distinguish between the parietal-frontal systems involved in the representation of acquired manual skills versus nonskilled actions.

The rule of law is a necessary condition for any substantive theory of justice. If a theory sacrifices the rule of law, justice, too, is sacrificed. The connection between the necessary condition and justice is explored in the work of John Rawls, H. L. A. Hart, Karl Marx, Emile Durkheim, Albert Camus and William Shakespeare. The conceptions of justice elaborated in each of these political thinker's works share very little more than the rule of law. Since the conceptions examined are (...) so different and the necessary condition is contained in each, I conclude that there is substantial support for the thesis. ;In order to do justice to the texts examined in this dissertation the plain language, the words on the page, must be given priority but cannot be fully determinative of the text's meaning. The immanent structure of the text, the rules of the text which give it shape and form, must also be discerned. There are no particular rules for interpretation in general, yet each text contains within it its own individual rules. The rules of the text are what allow the meanings of the text to play themselves out for different readers. Understanding the history of the text is also important for interpretation. ;Some interpretations of the theories of justice examined here have sought to change the substance of that theory through interpretation. For example, Marx's theory depends upon the law of equal commodity exchange. As shown in chapter three, if an alien supposition of distributive justice is interpreted into Marx's theory so that the surplus value which Marx claims belongs to the capitalist is redistributed, then the proposed transition to communism, which Marx analyzed and supported, will not occur. Doing justice to Marx's texts allows Marx's theory of justice to come through and be judged on its own terms. Only after that has been accomplished can it be evaluated and compared with other theories. The same association between interpretative method and substantive meaning is demonstrated for each theory. The conclusion compares interpretation in law and drama and connects doing justice to texts with justice. (shrink)
