Final answer:
Naomi Weisstein's 1991 critical work, initially published in 1968, identified the gender biases in psychology and was instrumental in spurring the development of feminist psychology.
Step-by-step explanation:
Naomi Weisstein in 1991, originally published in 1968, challenged the established psychological perspectives of that time, highlighting a significant gender bias within the field. Weisstein criticized how male psychologists had built the framework for understanding female psychology on their own cultural biases without rigorous experimental validation. She noted that these views, such as the comment from Bruno Bettleheim that women, regardless of their professional aspirations, prioritize being mothers and companions to men, failed to represent women accurately. Therefore, Weisstein's work is commonly identified as a seminal contribution to the birth of feminist psychology, aiming to create understanding free from male cultural biases. Her critique brought forth the need for a feminist approach in psychology to study women's psychologies with the same empirical rigor as any other aspect of psychology.
