The eyes have it: Young children's discrimination of age in masked and unmasked facial photographs

The ability of preschool children to discriminate age, and their use of information from different facial areas in this task, was investigated. Most 4-year-olds were able to rank sets of seven facial photographs into age order successfully. Subsequently, they were presented with facial stimuli in which different regions of the face were masked out. Masking of the eyes produced a marked performance decrement, and masking of the nose and cheeks a slight decrement, relative to masking of either the mouth and chin, or of the hair and neck. Possible explanations of the results are discussed, together with the verbal comments of the children on the cues they were aware of using.     

Effects of long- and variable-duration signals for food on activity,instrumental responding,and eating

Incentive-motivation theories typically assume that the conditioning of appetitive motivation involves the same parameters as Pavlovian salivary conditioning. In contrast, the Soltysik-Konorski model asserts that drive is inhibited by stimuli closely associated with food (salivary CSs) and augmented by stimuli more loosely associated with food (long and variable CS-US interval). Experiment 1 examined this latter proposition. Sixty-four rats were given extensive exposure to each of four environmental CSs, two while hungry and two while satiated. Within each deprivation condition, food was given 30–300 sec after placement of the rats in one environment, and was not given in the other environment. Performance on three separate measures—activity, lever-pressing, and food consumption—was higher in the environments previously associated with food. Experiment 2 examined the effects of discrete stimuli presented in advance of eating; in accord with the results of Experiment 1, food consumption was greater after a stimulus (1- to 9-min duration) previously paired with food than after no stimulus or after a stimulus unpaired with food. The overall results indicate (a) that stimuli associated with food become capable of facilitating a variety of food-directed behaviors, possibly via the conditioning of a common appetitive system, and (b) that a close association between the stimuli and food is not essential for such conditing to occur.     

The validity of the Holland and Basic Interest scales of the Strong Vocational Interest Blank: Leisure activities versus occupational membership as criteria

This study compared leisure activities with occupational membership as criteria for determining the concurrent validity of the Holland and Basic Interest scales of the Strong Vocational Interest Blank (Form T399). Subjects were 89 thirty-six-year-old males representing a variety of occupations. R. H. Dolliver's (Journal of Counseling Psychology, 1975, 22, 199–203) two methods for assessing validity were used: highest single scores on relevant scales and scores above established cutoff points on relevant scales. Results indicated greater congruence between interest scales and occupations than interest scales and leisure activities, except when Basic Interest scale cutoff scores were used. After chance factors were taken into account, Holland scales were found to be more accurate than Basic Interest scales in identifying occupations and in identifying leisure activities when highest scale scores were used. Using cutoff scores, Basic Interest scales were more accurate than Holland scales in identifying leisure activities. Supplementary analyses indicated that the validity of the Holland and Basic Interest scales increases when they are presumed to reflect either current occupation or preferred leisure activity. Results of this study were compared with Dolliver's (1975) findings.     

Science fictions: Comment on Godfrey-Smith

This is a comment on Peter Godfrey-Smith’s, “Models and Fictions in Science”. The comments explore problems he raises if we treat model systems as fictions in a naturalized and deflationary framework.     

Agents of Reform?: Children’s Literature and Philosophy

Children’s literature was first published in the eighteenth century at a time when the philosophical ideas of Jean-Jacques Rousseau on education and childhood were being discussed. Ironically, however, the first generation of children’s literature (by Maria Edgeworth et al) was incongruous with Rousseau’s ideas since the works were didactic, constraining and demanded passive acceptance from their readers. This instigated a deficit or reductionist model to represent childhood and children’s literature as simple and uncomplicated and led to children’s literature being overlooked and its contribution to philosophical discussions being undermined. Although Rousseau advocates freeing the child to develop, he does not feel that reading fiction promotes child development, which is a weakness in an otherwise strong argument for educational reform. Yet, rather ironically, the second generation of children’s writers, from Lewis Carroll onwards, more truly embraced Rousseau’s broader philosophical ideas on education and childhood than their predecessors, encouraging and freeing readers to imagine, reflect and actively engage in ontological enquiry. The emphasis had changed with the child being embraced in education and society as active participant rather than passive or disengaged recipient. Works deemed to be seminal to the canon of children’s literature such as Alice’s Adventures in Wonderland, Peter Pan and The Chronicles of Narnia challenge readers to work through conflicts many of which can be identified retrospectively as exhibiting postmodern characteristics. By exploring moral and spiritual dilemmas in their writing, Carroll, Barrie and Lewis’s works can be regarded as contributing to discussions on theodical postmodernism. The successes of The Lord of the Rings and Narnia films suggest that there is an interest in exploring moral dilemmas, fulfilling a need (perhaps for tolerance and understanding) in society at large. Children’s literature has an almost divine power to restore, to repair and to heal, all characteristics of theodical postmodernism but differing from the more widely held conception of postmodernism which pulls apart, exacerbates and exposes. Children’s literature therefore offers a healthy and constructive approach to working through moral dilemmas. In their deconstruction of childhood, these authors have brought children’s literature closer to aspects of enquiry traditionally found in the domain of adult mainstream literature. As the boundaries between childhood and adulthood become more fluid, less certain, debate is centring around whether the canon of children’s literature itself has become redundant or meaningless since there are no longer any restrictions on which subjects can be treated in children’s literature. Despite the fact that children’s literature clearly engages with difficult issues, it continues to be left out of the critical equation, not given serious attention, disregarded as simplistic and ignored in contemporary philosophical discussions concerning morality, postmodernism and the future of childhood. With children’s literature coming closer to mainstream literature, and exhibiting prominent features of postmodernism, however, it is only a matter of time before philosophical discussions actively engage with children’s literature and recognise its contribution to the resolution and reconciliation of ontological dilemmas. When this occurs, philosophy and children’s literature will re-engage, enriching contemporary investigations of existence, ethics and knowledge and fruitfully developing thought in these areas. This paper aims to contribute to this process.

Inference to the Best Explanation

The common role of research programs in science and religion is now widely accepted. The next step in the methodology debate is to specify more concretely the shared standards for adequate explanations. The article presents a detailed account of the method of inference to the best explanation and gives examples of how the method can structure the philosophical and theological interaction with science. The resulting approach dispenses with deductive and inductive proofs of religious propositions and limits itself to initially plausible hypotheses that are to be assessed according to their explanatory power. Only when a domain of data and a particular explanatory task have been specified can any serious claim be made that religious theories are equal or superior to their naturalistic alternatives.     

Marsilius of Padua and Peter of Abano: the scientific foundations of law-making in Defensor Pacis

This article shows that a forgotten source of Marsilius’ scientia of law-making in the Defensor Pacis is the Lucidator, the main astrological work of Peter of Abano. A compared analysis of these two works demonstrates that the theories of experientia and scientia that Marsilius considers necessary to make laws in the first dictio of the Defensor Pacis entirely draw on Peter of Abano’s views on the epistemological status of ‘the science of the stars’. It is shown that the purpose of Marsilius’ reinstatement of Peter of Abano’s theory of scientia is to build a science of law-making that does not need natural law and is based on experience and certain demonstrations.     

Vermigli Replicating Aquinas: An Overlooked Continuity in the Doctrine of Predestination

Although Peter Martyr Vermigli is well recognized for his integration of Thomism with Reformed theology, there is no consensus on whether to consider Thomas Aquinas a dominant influence on his doctrine of predestination. Recent scholarship argues that Gregory of Rimini’s influence is greater than Aquinas. This essay provides strong evidence to the contrary for the influence of Aquinas on Vermigli’s early exposition of predestination as a Reformer. Vermigli not only drew upon Aquinas’s doctrine in general, as he does elsewhere, but reproduced the details of Aquinas’s article in the Summa on whether foreknowledge of merits is the cause of predestination. This finding has significance for understanding the development of Vermigli’s thought, his relation to Thomist scholasticism, and his mature writings on predestination. In general, this evidence increases the importance of Thomas as a formative influence on Vermigli’s thought.     

INTO TERRA INCOGNITA: CHARTING BEYOND PETER HARRISON'S THE TERRITORIES OF SCIENCE AND RELIGION

Peter Harrison's The Territories of Science and Religion throws down a serious challenge to advocates of dialogue as the primary means of engagement between science and religion. This article accepts the validity of this challenge and looks at four possible responses to it. The first—a return to the past—is rejected. The remaining three—exploring new epistemic frameworks for the encounter of science and religion, broadening out the engagement beyond the context of the physical sciences and Western culture, and looking at ways in which scientific and theological practitioners may collaborate on practical problems—are all offered as potential ways in which science and religion may engage with one another, in ways which move beyond Harrison's critique.
