“I Want to Know More!”: Children Are Sensitive to Explanation Quality When Exploring New Information

When someone encounters an explanation perceived as weak, this may lead to a feeling of deprivation or tension that can be resolved by engaging in additional learning. This study examined to what extent children respond to weak explanations by seeking additional learning opportunities. Seven‐ to ten‐year‐olds (N = 81) explored questions and explanations (circular or mechanistic) about 12 animals using a novel Android tablet application. After rating the quality of an initial explanation, children could request and receive additional information or return to the main menu to choose a new animal to explore. Consistent with past research, there were both developmental and IQ‐related differences in how children evaluated explanation quality. But across development, children were more likely to request additional information in response to circular explanations than mechanistic explanations. Importantly, children were also more likely to request additional information in direct response to explanations that they themselves had assigned low ratings, regardless of explanation type. In addition, there was significant variability in both children's explanation evaluation and their exploration, suggesting important directions for future research. The findings support the deprivation theory of curiosity and offer implications for education.     

Technical filmmaking and scientific narratives: Has science overtaken fiction in recent science fiction? An analysis of Gravity,Interstellar, and The Martian

One can view the recent science fiction films Gravity, Interstellar, and The Martian as a three-part dialogue concerning the existential relationship between humanity, technology, and the science employed to create said technologies. Pitched into the deep of space, each film’s protagonist must seek to find technological answers to save their own existence. Each film’s exploration of these themes essentially questions the importance of technology as a product of scientific-calculative thinking and the validity of this thinking as the primary mode of understanding the world. In this article, I explore the existential dialogue crafted between these films through Walter Benjamin and Martin Heidegger. Through Benjamin, we will see how the medium of film is completely dependent upon technology to present its art and how this transforms the stories it tells, while also transforming the audience and the audience’s reality. Consequently, understanding the popular reception of these films becomes just as important as the films themselves for our present study. Through Heidegger, we will see how technology provides a space where we can find a truth about ourselves and our reality. However, modern technology’s increasing scientific complexity, created by scientists who in turn employ modern technology to further science, also conceals just as much as it reveals. These films provide us with an opportunity to explore a truth about our dependence upon technology even though, as technologically dependent works of art, they may also conceal how dependent upon science we have become when constructing our reality.     

A Property of Peculiar Value: Land,Religion and the Constitution

In 1792, James Madison wrote that a man's ‘property of peculiar value [is] in his religious opinions, and in the profession and practice dictated by them’.1 1. James Madison in the National Gazette (27 March 1792). Quoted in Hall (1998 Hall T 1998 Separating church and state: Roger Williams and religious liberty Champaign, IL University of Illinois Press  , 135). View all notes In view of the ensuing 200 years, the phrase is telling in ways Madison would not have anticipated. For it is in relation to land and private property that the constitutional concept of religion—a concept designed in significant part by Madison himself—arose and is now in decline. This article traces the origins, development and decline of religion as a constitutional concept in relation to land and private property. The experience of Native Americans is a particularly important illustration of this history, because it is in response to them that the constitutional relations of land and religion have been debated in most detail. I begin therefore with the unsuccessful efforts of Native Americans in 1988 to claim Free Exercise protection for lands they regard as sacred. The second section briefly explores the joint origins of private land ownership and the modern Western concept of religion, which in turn impacted the European treatment of the land and religions of conquered and colonised peoples. Moving into the American constitutional period, the third section sketches the inter-related notions of land and religion that appeared in key framers, which again had profound implications for indigenous peoples. Arriving at the present day, the fourth section outlines the deterioration of the constitutional concept of religion, along with the democratic public sphere itself, in the age of privatisation. The final section, using the Faith-Based Initiatives movement as an illustration, argues that new and supposedly public roles for religion actually advance and protect privatisation. In conclusion, I will review and assess very briefly the prospects for religion as a constitutional construct.     

Measurement of body image satisfaction using computer manipulation of a digital image

The authors investigated a method for assessing body image satisfaction based on computer manipulation of a digitized image of self using a sample of 56 female students aged 17 to 22 years. The total percentage change when re-sizing the actual image to the ideal by the computer adjustment method was significantly correlated with the figural/silhouette discrepancy method. Both of these measures were correlated significantly with body part satisfaction and body mass index but not with social physique anxiety. Although for this sample the 2 methods yielded similar results, the computer adjustment method addresses several limitations of the figural/silhouette method, such as scale coarseness and the accuracy of proportional change between figural/silhouettes. Furthermore, by using the individual's actual image, potential confounds associated with stylized figure drawings that are typically based on Caucasian physical features are removed. Finally, this method also takes into account the importance of various body parts for determining body image satisfaction.     

Plaudits and pitfalls in studying elite athletes

The study of elite athletes, because of their rarity, renders statistical power difficult to achieve, control groups difficult or impossible to find, and generalizability difficult to demonstrate. Alternative methods of analysis may be better suited to such study.     

Change and stability in adult intellectual functioning assessed by Wechsler item responses

Change in adult intellectual performance was assessed with longitudinal data from the Intergenerational Studies at the Institute of Human Development. Wechsler Intelligence data from two age cohorts spanning ages 18 to 61 were analyzed at the subtest and item level. Hotelling T2 analyses on sets of equivalent items from Wechsler subtests were studied to determine if change in response occurred between pairwise combinations of occasions of test administrations. We used Bowker's test to analyze data at the item level to determine the direction of change in performance. Consistent improvement in performance occurred between the ages of 18-40 and 18-54. Between the ages of 40 and 61, results showed mostly improved performance on the Information, Comprehension, and Vocabulary subtests, mixed change on the Picture Completion subtest, and decline on the Digit Symbol and Block Design subtests. The pattern of mixed change on the Picture Completion subtest indicated improvement on the easy items and decline on the difficult items. Decline in performance on the Block Design test occurred only for the most difficult items.     

Temporal coordination of phonation and articulation in a case of verbal apraxia: A voice onset time study

A study of voice onset time (VOT) in stop production was undertaken in order to investigate the hypothesis that the voicing feature errors in the speech of an apraxic patient (Sands, E. S., Freeman, F. J., & Harris, K. S. 1978. Brain and Language, 6, 97–105) were related to deficits in temporal coordination of phonation and articulation. Results demonstrated that the VOTs of the apraxic subject differed markedly from those of normal subjects. The apraxic productions did not include voicing lead for voiced stops. Lag times for voiced stops were longer than normal, while those for voiceless stops were shorter than normal, yielding a compression of the two categories and a marked overlap.     

Pictorial similarity judgments and the organization of visual memory in the rhesus monkey

The organization of visual memory for pictures was studied in the rhesus monkey. Two monkeys were tested in a same/different task in which sequentially presented pictures were compared to each other in a pair-wise fashion. The resulting confusion matrixes were analyzed using a multidimensional scaling procedure to obtain two- and three-dimensional graphic representations of the stimulus space. In Experiment 1, the monkeys' confusion errors caused pictures of human and rhesus monkey faces to fall in the same region of multidimensional space, which suggested that the monkeys categorized facial stimuli. A similar effect was found for pictures of different types of fruit. Experiment 2 replicated the categorization of faces with a more diverse collection of human and nonhuman primate faces. Experiment 3 explored the fruit category by varying stimulus attributes orthogonally. The results from this experiment showed that both monkeys encoded the pictures in this category by type of fruit (apples or grapes) and color (red or yellow). Taken together, these studies indicate that rhesus monkeys will treat some classes of pictorial stimuli categorically in visual memory.     

Cognitive training programs for childhood cancer patients and survivors: A critical review and future directions

A robust literature has developed documenting neurocognitive late effects in survivors of leukemia and central nervous system (CNS) tumors, the most frequent cancer diagnoses of childhood. Patterns of late effects include deficits in attention and concentration, working memory, processing speed, and executive function, as well as other domains. As childhood cancer survivors are living longer, ameliorating deficits both in broad and specific neurocognitive domains has been increasingly recognized as an endeavor of paramount importance. Interventions to improve cognitive functioning were first applied to the field of pediatric oncology in the 1990s, based on strategies used effectively with adults who had sustained a traumatic brain injury (TBI). Compilation and modification of these techniques has led to the development of structured cognitive training programs, with the effectiveness and feasibility of such interventions currently an active area of research. Consequently, the purpose of this critical review is to: (1) review cognitive training programs intended to remediate or prevent neurocognitive deficits in pediatric cancer patients and survivors, (2) critically analyze training program strengths and weaknesses to inform practice, and (3) provide recommendations for future directions of clinical care and research.     

Muslims,identity and multimodal communication on the internet

The Internet provides a space and medium within which Muslims can shape the relationship between their religious identity and their social and political affiliations. The subjectivities of Muslims who use online space are in turn shaped by the parameters and possibilities of the Internet’s architecture and language. The multiple linkages of online spaces and the particular vernacular spoken in these spaces, a mix of written text, imagery and sound, privilege new kinds of actors and new forms of expressive and rhetorical activities. In this new space and medium, the question of imagining (or rejecting) a global Muslim identity demonstrates the subtle interplay involved in the formation of religious and media subjectivities. Developing a critical understanding of multimodal representation and communication is an essential component in studying Muslim engagement with the Internet.
