The survey of 140 children under 16 in two subnormality hospitals showed that 3 per cent of the children had definitely been rendered mentally handicapped as a consequence of violent abuse, and that a possible maximum total of 11 per cent might have been thus rendered mentally handicapped. In 24 per cent of the children, neglect was considered to be a contributory factor in reducing intellectual potential. Impairment of intellect from abuse and neglect, especially in those with 'vulnerable' brains due to pre-existing abnormality, may be much commoner in children than is generally realized.
对两家低能儿医院的140名16岁以下儿童进行的调查显示，3%的儿童肯定因暴力虐待而导致智力障碍，可能多达11%的儿童也可能因此导致智力障碍。在24%的儿童中，忽视被认为是导致智力潜能降低的一个因素。虐待和忽视造成的智力损害，尤其是对那些因先前存在异常而大脑“脆弱”的儿童来说，可能比人们普遍意识到的更为常见。
