Scope and Contents Thomson begins by introducing the concept of individual differences in general terms, before moving on to his own topic of intelligence, and discussing the extent of individual intelligence differences. He illustrates the wideness of the intellectual range within the population by reproducing Cyril Burt's table, Distribution of Intelligence among Children and Adults, which contains suggested IQ scores for different levels of schooling and occupational complexity in...

Scope and Contents The lecture explores how schools could, and should, benefit the whole community by giving pupils a happy, clean environment which serves as a model for what the home should be, and by giving them the knowledge and skills in order to work towards solving practical and social problems in their communities. He illustrates this point with detailed descriptions of the Rachel MacMillan Nursery School in Deptford, London, and the Training School for Village Teachers at Chapra, Bengal....

Also includes a note from Thomson to Ledermann wishing him a happy Christmas and New Year.

Scope and Contents

Thomson tells Ledermann how glad he would be if, on leaving the University of St Andrews, he would take Lawley's vacated post. He makes him aware of the disadvantages of the post, in particular that it relies on a fund and as such is not permanent, and that would be an unconventional route from which to apply for possible future mathematics lectureships. He also states Emmett's pleasure at the possibility of working with Ledermann.

Scope and Contents

Thomson also thanks Ledermann for notes regarding proofs, and asks him if the date of his wedding is confirmed.

Scope and Contents

Thomson also invites Ledermann and his family to stay with Lady Thomson and himself in Edinburgh, referring to his improved health. He also tells Ledermann that he wants his view on an article in Psychometrika by A Finn.

Scope and Contents

Thomson informs Ledermann he will be speaking about their work on Factorial Analysis at a meeting of the Royal Society [of Edinburgh]. He asks Ledermann if he will also take part, along with Lawley.

Thomson stresses that, although the lectures are to be delivered to scientists, the scientific audience come from varied backgrounds, and as such the lectures should be easily understood.

Scope and Contents From the Fonds:

The collection largely consists of letters from Godfrey Thomson to Ledermann. Many are highly mathematical in content, containing formulae and mathematical notation, though they also regard social events and contain enquiries from Thomson with regards to the safety of Ledermann's family throughout the war.

Scope and Contents

Thomson remarks on a paper of Ledermann, highlighting corrections, and advises him with regards to slides for his Royal Society [of Edinburgh] lecture mentioned in his previous letter.

Also includes two sets of typescript notes titled Positive Structure in Factorial Analysis and Geometrical Illustrations of Factors and Correlations, most likely relating to the aforementioned lecture.

Scope and Contents The letter most likely refers to Y Ahmavaara's 1954 article, Transformation analysis of factorial data and other new analytical methods of differential psychology with their application to Thurstone's basic studies, from Annales Academiae Scientiarum Fennicae. In the letter, Thomson asks Ledermann to check if he is correct in his interpretation of the paper, referring to a chapter on m.v. selection in...
