The present paper studied the influence of long lasting blindness on p
rocesses of aging. It addressed the broader issue of the effects of fa
miliarity with and earlier experience of stress on the capacity of ind
ividuals to deal successfully with similar stressful situations at a l
ater point of development. 75 chronically blind men and women, aged 45
to 65, were compared with 75 sighted individuals (matched by age, sex
, and cultural origin) on scores on the Shanan Sentence Completion Tec
hnique, an interview designed to assess perception of change in variou
s areas of everyday living, and on scores on the Wechsler-Bellevue Int
elligence Test. Blind subjects showed less psychological and less soci
al engagement with the outer world. Availability of resources, educati
on, and assistance considerably reduced differences between the nonsig
hted and sighted subjects. These findings were interpreted as pointing
to a potentially preventable process of premature aging.
