Differential Psychology


differential psychology, branch of psychology that deals with individual and group differences in behaviour. Charles Darwin’s studies of the survival capabilities of different species and Sir Francis Galton’s researches on individual visual and auditory skills, as well as more recent experiments, have shown that both individual and group differences are quantitative rather than qualitative. Persons do not fall into sharply separated types, such as bright and dull, maladjusted and normal, introvert and extravert. On the contrary, in all psychological characteristics, individuals vary by degree along a continuous scale.

By: Jason Fields

Excerpt: Introduction; This report presents findings from the Survey of Income and Program Participation (SIPP) on the well-being of American children. While it may seem intuitive, the concept of child ?well-being? is difficult to conceptualize and measure. Recent research primarily assesses child well-being for two age groups; preadolescent children and young adults making the transition to adulthood. Preadolescents are often assessed using measures of cognitive develop...

Quantile Regressiony

Mathematics document containing theorems and formulas.

Excerpt: Francis Galton in a famous passage defending the charms of statistics against its many detractors, chided his statistical colleagues [who] limited their inquiries to Averages, and do not seem to revel in more comprehensive views. Their souls seem as dull to the charm of variety as that of a native of one of our at English counties, whose retrospect of Switzerland was that, if the mountains could be thrown into its lakes, two nuisances would be got rid of at once...

On the Reception of the 'Origin of Species

By: Thomas Henry Huxley

ON THE RECEPTION OF THE ?ORIGIN OF SPECIES. To the present generation, that is to say, the people a few years on the hither and thither side of thirty, the name of Charles Darwin stands alongside of those of Isaac Newton and Michael Faraday; and, like them, calls up the grand ideal of a searcher after truth and interpreter of Nature. They think of him who bore it as a rare combination of genius, industry, and unswerving veracity, who earned his place among the most famou...

Darwiniana

By: Thomas Henry Huxley

Preface: I have entitled this volume ?Darwiniana? because the pieces republished in it either treat of the ancient doctrine of Evolution, rehabilitated and placed upon a sound scientific foundation, since and in consequence of, the publication of the ?Origin of Species;? or they attempt to meet the more weighty of the unsparing criticisms with which that great work was visited for several years after its appearance; or they record the impression left by the personality o...

Darwiniana : Essays and Reviews Pertaining to Darwinism

By: Asa Gray

Preface: These papers are now collected at the request of friends and correspondents, who think that they may be useful; and two new essays are added. Most of the articles were written as occasion called for them within the past sixteen years, and contributed to various periodicals, with little thought of their forming a series, and none of ever bringing them together into a volume, although one of them (the third) was once reprinted in a pamphlet form. It is, therefore,...

Luck or Cunning?

By: Samuel Butler

Excerpt: This book, as I have said in my concluding chapter, has turned out very different from the one I had it in my mind to write when I began it. It arose out of a conversation with the late Mr. Alfred Tylor soon after his paper on the growth of trees and protoplasmic continuity was read before the Linnean Society that is to say, in December, 1884 and I proposed to make the theory concerning the subdivision of organic life into animal and vegetable, which I have broa...

Description: INGV – Istituto Nazionale di Geofisica e Vulcanologia, Via Vigna Murata 605, 00143 Rome, Italy. During his trip on the Beagle, Charles Darwin wrote about the eruptions associated with the Concepción earthquake of 1835. A later survey by Lorenzo Casertano, following the great 1960 Chilean earthquake, identified some unclear evidence of a link between eruptions and the seismic event, although some reservations were also raised. Using data available in 2006...

Plos Biology : Functional Imaging of Numerical Processing in Adult...

By: Stanislas Dehaene

Description : Adult humans, infants, pre-school children, and non-human animals appear to share a system of approximate numerical processing for non-symbolic stimuli such as arrays of dots or sequences of tones. Behavioral studies of adult humans implicate a link between these non-symbolic numerical abilities and symbolic numerical processing (e.g., similar distance effects in accuracy and reaction-time for arrays of dots and Arabic numerals). However, neuroimaging studi...
