TL;DR: Among the authors' patients was a bookkeeper with a severe form of sensory aphasia who could still draw up the annual balance sheet in spite of severe disturbances of speech and although he was unable to remember the names of his subordinates and used to refer to them incorrectly.

TL;DR: In this paper, an inventory of 20 items with a set of instructions and response-and computational-conventions is proposed and the results obtained from a young adult population numbering some 1100 individuals are reported.
Abstract: The need for a simply applied quantitative assessment of handedness is discussed and some previous forms reviewed. An inventory of 20 items with a set of instructions and response- and computational-conventions is proposed and the results obtained from a young adult population numbering some 1100 individuals are reported. The separate items are examined from the point of view of sex, cultural and socio-economic factors which might appertain to them and also of their inter-relationship to each other and to the measure com- puted from them all. Criteria derived from these considerations are then applied to eliminate 10 of the original 20 items and the results recomputed to provide frequency-distribution and cumulative frequency functions and a revised item-analysis. The difference of incidence of handedness between the sexes is discussed.

TL;DR: This paper would never have been written without Professor Zangwill’s urging, and I am grateful to him for having brought me to a more careful review of the older literature and a more precise statement of my own ideas.
Abstract: As I have pointed out earlier, when I met Oliver Zangwill in 1961 at a meeting on dyslexia in Baltimore, he listened patiently to the exposition of my ideas on the significance of the cortico-cortical connections for the higher functions. A short time later, while on a trip to Boston, he suggested to me that I should prepare an extended account of these ideas. This paper would never have been written without Professor Zangwill’s urging, and I am grateful to him for having brought me to a more careful review of the older literature and a more precise statement of my own ideas. Although Russell Brain, who was then the editor of Brain, had some misgivings about the section on philosophical implications he agreed to take the manuscript unchanged.

TL;DR: The hypothesis is that slowed growth within certain zones of the left hemisphere is likely to result in enlargement of other cortical regions, in particular, the homologous contralateral area, but also adjacent unfaffected regions.
Abstract: Part two of this three-part series commences with anomalous dominance and special talents. Part one appears in a previous issue of theArchives. 1 ANOMALOUS DOMINANCE AND SPECIAL TALENTS According to our hypothesis, slowed growth within certain zones of the left hemisphere is likely to result in enlargement of other cortical regions, in particular, the homologous contralateral area, but also adjacent unfaffected regions. The influences that favor anomalous dominance may thus favor talents associated with superior development of certain regions either in the right hemisphere or in adjacent parts of the left hemisphere. Even with excessive retardation of growth and the resultant migration abnormalities and learning disorders (LD), high talents may exist as a result of compensatory enlargement of other cortical regions. Several types of data are in concordance with these conclusions. Several studies have claimed that the average level of spatial talents is higher in male subiects. 2 Hier
