Differences in concentration ability among low- and high-SES Israeli students: a follow-up study.

Eighty students participated in a follow-up study investigating the relationship between the ability to concentrate and academic achievement among low-socioeconomic-status (LSES) and high-socioeconomic-status (HSES) 4th grades. The results indicated that the differences between the ability to concentrate and academic achievement found when the students were in the 1st grade (Norman & Breznitz, 1992) persisted, in part, to the 4th grade. Compared with HSES children, LSES children obtained significantly lower scores on measures of academic achievement and concentration. Additional measures of school behavior included in the present study revealed that LSES children were more likely to be characterized by aggressive-impulsive behavior. This behavior accounted for most of the differences found between HSES and LSES pupils on the academic and concentration measures.
