Mental Chronometry (MC) comprises a variety of techniques for measuring the speed with which the brain processes information.First developed in mid-1800, MC was subsequently eclipsed by more complex and practically useful types of psychometric tests stemming from Alfred Binet. This class of mental tests, however, has no true metric relating the test scores to any specific properties of the brain per se. The scores merely represent an ordinal scale, only ranking individuals according to their overall performance on a variety of complex mental tasks. The resulting scores represent no more than ranks rather than being a true metrical scale of any specific dimension of brain function. Such an ordinal scale, which merely ranks individuals in some defined population, possesses no true scale properties, possessing neither a true zero or equal intervals throughout the scale. This deficiency obstructs the development of a true natural science of mental ability. The present burgeoning interest in understanding individual differences in mental abilities in terms of the natural sciences, biology and the brain sciences in particular, demands direct measures that functionally link brain and behavior. One such natural ratio scale is time itself - the time it takes the brain to perform some elementary cognitive task, measured in milliseconds. After more than 25 years researching MC, Jensen here presents results on an absolute scale showing times for intake of visual and auditory information, for accessing short-term and long-term memory, and other cognitive skills, as a function of age, at yearly intervals from 3 to 80 years. The possible uses of MC in neurological diagnosis and the monitoring of drug effects on cognition, the chronometric study of special time-sensitive talents such as musical performance, and presents a theory of general intelligence, or g, as a function of the rate of oscillation of neural action potentials as measured by chronometric methods. Finally, Jensen urges the world-wide standardization of chronometric methods as necessary for advancing MC as a crucial branch of biopsychological science. - Provides a different scale to report Mental Chronometry (MC) findings - Argues for the global adoption of an absolute scale as opposed to the traditional ordinal scale - An important contribution to MC researchers and psychologists and neuroscientists
The study of attention in the laboratory has been crucial to understanding the mechanisms that support several different facets of attentional processing: Our ability to both divide attention among multiple tasks and stimuli, and selectively focus it on task-relevant information, while ignoring distracting task-irrelevant information, as well as how top-down and bottom-up factors influence the way that attention is directed within and across modalities. Equally important, however, is research that has attempted to scale up to the real world this empirical work on attention that has traditionally been well controlled by limited laboratory paradigms and phenomena. These types of basic and theoretically guided applied research on attention have benefited immeasurably from the work of Christopher Wickens. This book honors Wickens' many important contributions to the study of attention by bringing together researchers who examine real-world attentional problems and questions in light of attentional theory. The research fostered by Wickens' contributions will enrich not only our understanding of human performance in complex real-world systems, but also reveal the gaps on our knowledge of basic attentional processes.
Jensen is a controversial figure, largely for his conclusions based on his and other research regarding the causes of race based differences in intelligence and in this book he develops more fully the argument he formulated in his controversial Harvard Education Review article ‘How Much Can We Boost IQ and Scholastic Achievement?’. In a wide-ranging survey of the evidence he argues that measured IQ reveals a strong hereditary component and he argues that the system of education which assumes an almost wholly environmentalist view of the causes of group differences capitalizes on a relatively narrow category of human abilities. Since its original publication the controversy surrounding Jensen’s ideas has continued as successive generations of psychologists, scientists and policy-makers have grappled with the same issues.
Among particular issues discussed in this book are the problems of the cultural disadvantaged, the problems of devising psychological tests which are not biased towards any particular culture, the problems of minority groups of children in education and the relationship between heritability and teachability.
This book is for those of the general public who want to learn more about mental testing and its controversies. It presupposes no background in the specialized terminologies or mathematical underpinnings of psychometrics, statistics, or quantitative genetics that make most of the serious literature on the "IQ controversy" so inaccessible to the educated public who are not professionals in the field of mental measurement.
This book celebrates two triumphs in modern psychology: the successful development and application of a solid measure of general intelligence; and the personal courage and skills of the man who made this possible - Arthur R. Jensen from Berkeley University. The volume traces the history of intelligence from the early 19th century approaches, to the most recent analyses of the hierarchical structure of cognitive abilities, and documents the transition from a hopelessly confused concept of intelligence to the development of an objective measure of psychometric g. The contributions illustrate the impressive power g has with respect to predicting educational achievement, getting an attractive job, or social stratification. The book is divided into six parts as follows: Part I presents the most recent higher-stream analysis of cognitive abilities, Part II deals with biological aspects of g, such as research on brain imaging, glucose uptake, working memory, reaction time, inspection time, and other biological correlates, and concludes with the latest findings in g-related molecular genetics. Part III addresses demographic aspects of g, such as geographic-, race-, and sex-differences, and introduces differential psychological aspects as well. Part IV concentrates on the g nexus, and relates such highly diverse topics as sociology, genius, retardation, training, education, jobs, and crime to g. Part V contains chapters critical of research on g and its genetic relationship, and also presents a rejoinder. Part VI looks at one of the greatest contemporary psychologists, Professor Emeritus Arthur R. Jensen as teacher and mentor.
I am unaware of any textbook which provides such comprehensive coverage of the field and doubt that this work will be surpassed in the foreseeable future, if ever!' From the foreword by Robert C. Moellering, Jr., M.D, Shields Warren-Mallinckrodt Professor of Medical Research, Harvard Medical School, USA Kucers' The Use of Antibiotics is the leading major reference work in this vast and rapidly developing field. More than doubled in length compared to the fifth edition, the sixth edition comprises 3000 pages over 2-volumes in order to cover all new and existing therapies, and emerging drugs not yet fully licensed. Concentrating on the treatment of infectious diseases, the content is divided into 4 sections: antibiotics, anti-fungal drugs, anti-parasitic drugs and anti-viral drugs, and is highly structured for ease of reference.Within each section, each chapter is structured to cover susceptibility, formulations and dosing (adult and paediatric), pharmacokinetics and pharmacodynamics, toxicity and drug distribution, detailed discussion regarding clinical uses, a feature unique to this title. Compiled by an expanded team of internationally renowned and respected editors, with a vast number of contributors spanning Europe, Africa, Asia, Australia, South America, the US and Canada, the sixth edition adopts a truly global approach. It will remain invaluable for anyone using antimicrobial agents in their clinical practice and provides in a systematic and concise manner all the information required when treating infections requiring antimicrobial therapy.
