This summary is similar to that in All About Women: What Big Sister Doesn’t Want You to Know. Sexual signals are given particular emphasis in the Procedural Analysis system because their evolutionary viability is obvious. Each of these signals is advantageous (it has a reason to exist, being employed to attract a mate) and heritable (has a means to exist, capable of being passed on to the progeny resulting from that union).

• ACCIDENT. Things being dropped, bicycle accidents and similar mishaps.
• ASSENT. A female subtly conveys her decision to accept a male for sex.
• BLANCH. (m/f) A subtle involuntary facial signal indicating attraction.

• BODY TREMOR. The body is rocked from side to side to emphasize the breasts.
• BRIGHTENING. The female stiffens and smiles as a target male nears.
• CHALLENGE. (m/f) A display of defiance; subtle and overt forms exist.
