The Life Space of a Scientist: The Visionary Function and Other Aspects of Jean Piaget's Thinking

This article (a) sketches briefly some systematic aspects of creative work as part of the rationale for the use of the case study method, (b) outlines a spectrum of processes that can be grouped as the 'visionary function,' which includes metaphor and other figures of thought, and (c) illustrates the previous points by examining both Jean Piaget's creative work and his ideas about creative work, drawing on unpublished interviews and other sources. Special attention is given to an example of metaphors and other figures of thought that play important roles in Piaget's thinking. These include the circle of the sciences, nourishment and growth, biology and knowledge, toys, projection, possibilities, incubation, writing as thinking, internal logic, music, morality and structure, adolescent dreamer, ascent, and ascending equilibration.     

Religiosity and the mental health of adolescents in Great Britain

Most studies show that religion is a protective factor for mental health. A few argue that it is detrimental and the remainder conclude it makes no difference. We investigate the religiosity correlates of childhood psychopathology – strength of belief, importance of being able to practice one’s religion, and worship frequency. Questions on religiosity were included in the mental health survey of children in Great Britain administered to 2992 11–19-year-olds in 2007. The Development and Well-Being Assessment was used to generate rates of clinically recognisable mental disorders. Logistic regression analysis was used to establish the magnitude of the religiosity correlates of emotional and conduct disorders. Young people with a stated religion who had weakly held beliefs or who regarded religious practice as unimportant were those with the greater likelihood of having emotional disorders. Regular attendance at religious services or prayer meetings reduced the likelihood of having a conduct disorder.     

Direct and indirect measures of frequency monitoring in young and elderly adults

Memory for frequency of occurrence of novel material (Turkish words) was investigated in young and elderly adults via direct (absolute and relative frequency judgments) and indirect (reading speed) measures. Both young and elderly adults showed increased reading speed as a function of frequency of occurrence (Experiment 1). However, when asked explicitly to identify how often a word occurred (Experiment 1) or which word occurred more often (Experiment 2), elderly subjects were less accurate than young adults. These results support and extend research on age-related dissociations in memory.     

Creatine Supplementation and Cognitive Performance in Elderly Individuals

ABSTRACT

The purpose of this study was to examine the effect of creatine supplementation on the cognitive performance of elderly people. Participants were divided into two groups, which were tested on random number generation, forward and backward number and spatial recall, and long-term memory tasks to establish a baseline level. Group 1 (n?=?15) were given 5 g four times a day of placebo for 1 week, followed by the same dosage of creatine for the second week. Group 2 (n?=?17) were given placebo both weeks. Participants were retested at the end of each week. Results showed a significant effect of creatine supplementation on all tasks except backward number recall. It was concluded that creatine supplementation aids cognition in the elderly.     

Religion and bioethics: toward an expanded understanding

Before asking what U.S. bioethics might learn from a more comprehensive and more nuanced understanding of Islamic religion, history, and culture, a prior question is, how should bioethics think about religion? Two sets of commonly held assumptions impede further progress and insight. The first involves what “religion” means and how one should study it. The second is a prominent philosophical view of the role of religion in a diverse, democratic society. To move beyond these assumptions, it helps to view religion as lived experience as well as a body of doctrine and to see that religious differences and controversies should be welcomed in the public square of a diverse democratic society rather than merely tolerated.     

The perception of object versus objectless motion

Wertheimer, M. (Zeitschrift für Psychologie und Physiologie der Sinnesorgane, 61:161–265, 1912) classical distinction between beta (object) and phi (objectless) motion is elaborated here in a series of experiments concerning competition between two qualitatively different motion percepts, induced by sequential changes in luminance for two-dimensional geometric objects composed of rectangular surfaces. One of these percepts is of spreading-luminance motion that continuously sweeps across the entire object; it exhibits shape invariance and is perceived most strongly for fast speeds. Significantly for the characterization of phi as objectless motion, the spreading luminance does not involve surface boundaries or any other feature; the percept is driven solely by spatiotemporal changes in luminance. Alternatively, and for relatively slow speeds, a discrete series of edge motions can be perceived in the direction opposite to spreading-luminance motion. Akin to beta motion, the edges appear to move through intermediate positions within the object’s changing surfaces. Significantly for the characterization of beta as object motion, edge motion exhibits shape dependence and is based on the detection of oppositely signed changes in contrast (i.e., counterchange) for features essential to the determination of an object’s shape, the boundaries separating its surfaces. These results are consistent with area MT neurons that differ with respect to speed preference Newsome et al (Journal of Neurophysiology, 55:1340–1351, 1986) and shape dependence Zeki (Journal of Physiology, 236:549–573, 1974).     

Relationship Quality,Commitment, and Stability in Long‐Distance Relationships

Using a nationally representative sample (N = 870), the present study compared long‐distance romantic relationships to close‐proximity romantic relationships in terms of relationship quality, commitment, and stability. Individuals in long‐distance relationships generally reported higher levels of relationship quality on a number of relationship quality variables, as well as higher levels of dedication to their relationships and lower levels of feeling trapped (i.e., felt constraint), but were similar to individuals in close‐proximity relationships in terms of perceived and material constraints. Although individuals in long‐distance relationships perceived a lower likelihood of breaking up with their partner at the initial time point, they were as likely as the individuals in close‐proximity relationships to have broken up by the follow‐up assessment.     

‘Everyone’, consequences,and generalization arguments

This paper addresses issues raised by recent discussion in normative ethics which concern relations between properties of individual actions and of certain groups of actions. First, an ambiguity common to ‘everyone can’ and ‘everyone ought’ is examined. Next, a similar ambiguity in talk about consequences is studied; here several procedures for identifying and evaluating consequences are compared. Then a notation that untangles the ambiguities is presented. Next, this notation is employed in an analysis of Marcus Singer's deduction of his generalization argument. Finally, there is a study of the question as to whether or not conflicts are possible between Singer's generalization argument and the dictates of consequences of individual actions. The findings are that such conflicts are or are not possible depending upon how a certain restriction on generalization arguments is interpreted, and that in either case the proponent of generalization arguments is faced with problems.
