Violence and U.S. regional culture.

The US South, and western regions of the US initially settled by Southerners, are more violent than the rest of the country. Homicide rates for White Southern males are substantially higher than those for White Northern males, especially in rural areas. But only for argument-related homicides are Southern rates higher. Southerners do not endorse violence more than do Northerners when survey questions are expressed in general terms, but they are more inclined to endorse violence for protection and in response to insults. Southern Ss responded with more apparent anger to insults than did Northerners and were more likely to propose violent solutions to conflicts presented in scenarios after being insulted. The social matrix that produced this pattern may be the culture of honor characteristic of particular economic circumstances, including the herding society of the early South. Consistent with this possibility, the herding regions of the South are still the most violent. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

H. H. Goddard and the immigrants.

Responds to comments by D. D. Dorfman (see record 1982-25821-001), D. Gersh (see record 1982-25825-001), R. J. Herrnstein (1981), and L. J. Kamin (see record 1982-25833-001) on the source of data cited in H. H. Goddard's (1917) article on mental tests with immigrants. An attempt is made to clarify what the cited data about the immigrants represent. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Structural bonding contributions and the elastic response of b.c.c. and f.c.c. crystals

The anisotropic elastic response of body centered cubic (b.c.c.) and face centered cubic (f.c.c.) crystals is reviewed within the framework of general elasticity and particular model dependent relations. It is found that important trends in the observed behavior of specific groups of crystals can be reproduced by models that include only structural contributions to crystal binding. In fact, a very simple model, consisting of only nearest and next nearest neighbor interactions, reproduces the salient behavior, including the algebraic signs of Poisson's ratio and the orderings of the shear moduli, Young's moduli, and Poisson's ratios associated with major crystallographic symmetries. The analysis provides insight into the differences between the b.c.c. transition metals and the b.c.c. alkali metals.     

Relationship between rolling textures and shear textures in f.c.c. and b.c.c. metals

The rolling and shear textures of aluminium (f.c.c.) and Fe-16% Cr (b.c.c.) have been compared. First a 90° rotation relationship about the transverse direction was found experimentally between the stable orientations of the rolling textures and the shear textures. This was explained with the symmetry of the glide systems and the orientation relationship between both coordinate systems. Second for both kinds of deformation namely rolling and shear a 90° rotation relationship about the transverse direction was also found between the stable b.c.c. and f.c.c. orientations. This was explained with the Taylor theory and the Sachs model making use of the orientation relationship between f.c.c. and b.c.c. glide systems.     

Deep dyslexia and the right hemisphere hypothesis: Evidence from the U.S.A. and the U.S.S.R.

Discusses the theory that asserts that the residual reading abilities seen in deep dyslexia entirely reflect the operation of an intact right hemisphere reading system rather than a partially disabled left hemisphere reading system. Evidence from an experiment with normal Ss in a report by the present author and colleagues (1983) is presented, which suggests that the right hemisphere contains no lexical entries for abbreviations that can be accessed by visual presentation. Data are presented from studies by K. E. Patterson (1980; see also PA, Vols 63:12203 and 64:10691) on 2 male deep dyslexic's understanding of printed abbreviations, along with observations of a young female deep dyslexic who was tested on understanding of abbreviations and on letter-naming abilities. Considerable sparing of the ability to obtain semantic information from printed abbreviations was evidenced in all 3 Ss. This contrast suggests that the current right hemisphere account of the residual reading abilities seen in deep dyslexia is not a sufficient one and should be modified.

U.S. psychology and world psychology.

Contends that although US psychology at present occupies a major position in world psychology, the field is growing more rapidly in many other countries. An example of international cooperation in an endeavor that could not be achieved by the psychological community of any single nation (i.e., securing the admission of the International Union of Psychological Science to the International Council of Scientific Unions) is given. A list of suggestions is presented outlining ways in which individual psychologists can take part in international psychological activities.

J. P. Guilford: Psychologist and teacher.

A review of the life and contributions of one of the foremost psychologists of our time. The review covers the contributions of Guilford to experimental psychology—experimental esthetics, sensory processes, perception, and learning; statistical psychology—psychophysics, analysis, test theory and evaluation; measurement of mental abilities—aptitudes of high level personnel, structure of the intellect, and creativity; and personality—tests, questionnaires, and inventories by Guilford and his associates. A complete bibliography shows that Guilford published either as sole author or as co-author 21 books; 29 monographs; 158 articles; and 21 tests, manuals, and profile sheets. A portrait of Guilford is included. (7-p. bibliogr.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
