What's So Creative About Creativity? PDF Versão para impressão Enviar por E-mail

Although technology enables us to live, the fine arts explain why we live. Consequently, within the past 30 years a fascination with the creative process and with creativity itself has come into its own. This movement toward understanding human creativity has resulted in an abundance of scientific research material. More than ever before, standardized tests for creativity abound. Many of them are psychometrically valid and reliable measures of creative temperament and product. At last! Psychology freely acknowledges that all progress toward understanding a meaningful existence is essentially a direct consequence of human creativity.

Reproduction Technology for a New Eugenics PDF Versão para impressão Enviar por E-mail

The first century or two of the new millennium will almost certainly be a golden age for eugenics. Through application of new genetic knowledge and reproductive technologies the Galtonian Revolution will come to fruition. This new revolution in the new millennium, which I call the Galtonian Revolution (Whitney, 1995; 1997a) will be more momentous for the future of mankind than was the Copernican Revolution or the Darwinian Revolution. For with the Galtonian Revolution, for the first time, the major changes will not be to ideas alone, but rather the major change will be to mankind itself.

A resolution of the normal IQ but small brain anomaly PDF Versão para impressão Enviar por E-mail

Why do modern humans have larger brains than earlier people such as Homo erectus? Since large brains cause obstetrics, infancy and locomotion problems, the advantage they offer must be substantial. One might link this advantage to increased IQ. But there is a problem: individuals exist with psychometrically normal IQ but Homo erectus sized brains (MRI volumetric surveys outliers, microcephaly and hemispherectomy). Why did evolution increase brain size (with all its complications) when humans (as these individuals demonstrate) can have normal IQ without bigger brains? Here I argue the advantage links to increased capacity for expertise, an aspect of intelligent behaviour not measured by IQ tests, that both links to brain size and would have been critical to the survival of our simple hunter-gatherers ancestors.

Does Brain size matter ?, a reply to Rushton and Ankney PDF Versão para impressão Enviar por E-mail

Rushton and Ankney (1995) show that new Magnetic Resonance Imaging mri studies allow the statement that brain size and IQ are correlated. However, the evidence does not justify statements about the relation of brain size and IQ across race and sex. Rushto n & Ankney's comparisons of brain size across races are based on brain weights corrected for body weights, but the corrections are not justifiable for within-species comparisons. Large variations of brain size within race groupings (as defined by Rushton & Ankney), and large secular changes in brain size add to doubts about the validity of Rushton & Ankney's arguments about race/brain size/IQ relations. Rushton & Ankney suggest that sex differences in brain size relate to sex differences in IQ and spatial abilities; however, the sex differences in IQ do not stand in proportion to differences in brain size, and spatial performance in women does not correlate with brain size. Scaling brain size across sexes remains an unsolved problem.

Race, Intelligence and the Brain PDF Versão para impressão Enviar por E-mail

The first edition of The Mismeasure of Man appeared in 1981 and was quickly praised in the popular press as a definitive refutation of 100 years of scientific work on race, brain-size and intelligence. It sold 125,000 copies, was translated into 10 languages, and became required reading for undergraduate and even graduate classes in anthropology, psychology, and sociology. The second edition is not truly revised, but rather only expanded, as the author claims the book needed no updating as any new research would only be plagued with the same philosophical errors revealed in the first edition. Thus it continues a political polemic, whose author engages in character assassination of long deceased scientists whose work he misrepresents despite published refutations, while studiously witholding from his readers fifteen years of new research that contradicts every major scientific argument he puts forth. Specific attention in this review are given to the following topics: (1) the relationship between brain size and IQ, (2) the importance of the scientific contributions of Sir Francis Galton, S. G. Morton, H. H. Goddard, and Sir Cyril Burt, (3) the role of early IQ testers in determining U.S. immigration policy, (4) The Bell Curve controversy and the reality of g, (5) race/sex/social class differences in brain size and IQ, (6) Cesare Lombroso and the genetic basis of criminal behavior, (7) between-group heritabilities, inter-racial adoption studies, and IQ (8) why evolutionary theory predicts group differences, and (9) the extent to which Gould's political ideology has affected his scientific work.

IQ Will Put You In Your Place PDF Versão para impressão Enviar por E-mail

Imagine several hundred families which face few of the usual problems that plague modern society. Unemployment is zero. Illegitimacy is zero. Divorce is rare and occurs only after the children's most formative years. Poverty is absent - indeed, none of the families is anywhere near the poverty level. Many are affluent and all have enough income to live in decent neighbourhoods with good schools and a low crime rate. If you have the good fortune to come from such a background, you will expect a bright future for your children. You will certainly have provided them with all the advantages society has to offer. But suppose we follow the children of these families into adulthood. How will they actually fare?

Acceleration: A Coat of Many Colours PDF Versão para impressão Enviar por E-mail

Why does the word 'acceleration' continue to generate controversy? The research literature now makes it abundantly clear that acceleration in its various guises is a positive intervention for many gifted students. Nevertheless, educational practitioners in Australia continue to resist the evidence and campaign actively against allowing students to take up this option. This paper synthesises three research projects conducted in New South Wales , exploring different forms of acceleration. The first project involved an investigation of the Early Entry policy for gifted children in one region of the state; the second reports on a number of case studies of students who have received at least one instance of grade-skipping; and the third, examines a vertical programming system that allows students to accelerate within subjects at a selective high school. Based on these research studies, this paper will explore the issues that are at the centre of the acceleration debate.
