Cutler,Friedman and McCoy (1998)
Aim: Investigate if a synthesised human pheromone can increase sociosexual behaviour of men.
Procedure: Men aged between 25-42 years old, field experiment. Each man was asked to use their aftershave everyday and fill out a behavioural calendar consisting of affection, sleeping next to a romantic partner, intercourse,informal date, formal date,masterbation for two weeks. They added either ethonal or a pheromone to the aftershave.Then another six weeks filled in.
Result: A larger number of the pheromone group had an increase with the first 4 activities, no change in last two. This could be due to the pheromones or his own tibido or a woman coming to him giving an indefinite answer.
