In connection with these works La Rocca made specific reference to the female life experience, which had only ascribed certain activities to women’s hands.

It is better to embroider with words...“ Near the end of her career La Rocca worked in "Riduzioni" (reductions), in which she transforms a common photograph, such as a family or individual portrait, into something more graphic.

During this time she created several works in black PVC plastic, often reproducing single letters of the alphabet and punctuation marks (mainly the comma), and various objects in metal and mirror.

Her initial steps during this phase included her book "In principio erat" (1971), which Lea Vergine cited as one of the fundamental experiences of Italian body art; and La Rocca's video “Appendice per una supplica”, shown for the first time at the 1972 Biennale di Venezia.

La Rocca constructed her unique aesthetic language working with materials as different as the letters of the alphabet, hand gestures, x-rays of her own head, and the practice of automatic writing.

Several retrospectives have been organized in Italy, Europe and the United States, in public and private spaces, such as: One piece of La Rocca's work was acquired by the Uffizi, for exhibition in its wing[17] of the Corridoio Vasariano.
