Attracting interest: Dynamic displays of proceptivity increase the attractiveness of men and women

From the book : Evolutionary Psychology 6 issue 4 : 563-574.
Proceptive signals may influence judgments of opposite-sex attractiveness because these signals indicate high mate quality and/or non-threatening behavior but they may also signal high probable rate of return for mating effort.
If so, individuals observing these signals may be sensitive to where the signals are directed to; signals directed toward other individuals may not predict what signals would be directed toward the observer.
To explore these possibilities I made use of video stimuli composed of mock interviews with actors.
Each actor did one proceptive and one unreceptive interview.
Each interview was presented as being directed toward participants or toward an opposite sex interviewer.
Proceptivity enhanced the attractiveness of opposite-sex actors and an interaction between proceptive state and signal direction was found, with this pattern varying substantially between actors.
The possibility that this variation is mediated by the physical attractiveness and sex of the actors will be discussed.
