visual field defect

a reduction in the normal extent of the visual field, characterized by partial or total blindness. This is caused by an interruption in the flow of visual impulses between the retina and the visual cortex, which may be caused by a lesion before, after, or in the optic chiasm or in all or a part of the optic radiations; it can involve tracts of one or both eyes. Each possible lesion produces a different defect.

secondary coping

secondary coping

a stress-management strategy in which a person seeks to adjust his or her hopes, expectations, attributions, and other aspects of the self to achieve a better fit with current events and prevailing conditions. This adaptation of oneself to the environment represents a more internally focused coping strategy that generally is applied when stressors cannot easily be counteracted directly. It includes such mental actions as distraction, positive thinking, cognitive restructuring, and rethinking about the stressor or problem in such a way as to facilitate acceptance. Also called secondary control coping. Compare primary coping. [identified in 1982 by Fred M. Rothbaum (1949–2011) and John R. Weisz (1945–  ), U.S. clinical and developmental psychologists, and Samuel S. Snyder, U.S. developmental psychologist]
