In an effort to curb the abuse, the Social Security Administration voided the “Woolworth” number (they gave Hilda a new one) and did what they could to publicize that people should not use it, but the number continued to turn up as late as 1977, when twelve people were found to still be using the SSN “issued by Woolworth.” (The previous year, forty people had that notion, so at least things were getting better.) In all, over 40,000 people have reported the Woolworth number as their own throughout the years.
The term 'Invalidating Environment' refers essentially to a situation in which the personal experiences and responses of the growing child are disqualified or "invalidated" by the significant others in her life.
The child's personal communications are not accepted as an accurate indication of her true feelings and it is implied that, if they were accurate, then such feelings would not be a valid response to circumstances.
Any failure on the part of the child to perform to the expected standard is therefore ascribed to lack of motivation or some other negative characteristic of her character.
