Walster and Walster ran a follow up to the Computer Dance, but instead allowed participants to meet beforehand in order to give them greater chance to interact and think about their ideal qualities in a partner.
Huston attempted to prove this by showing participants photos of people who had already indicated that they would accept the participant as a partner.
Longer exposure may have changed the attraction ratings.
In a follow up of the experiment, it was found that couples were more likely to continue interacting if they held similar attraction ratings.
Murstein also found evidence that supported the matching hypothesis.
Photos of 197 couples in various statuses of relationship (from casually dating to married), were rated in terms of attractiveness by eight judges. The judges did not know which photographs went together within romantic partnerships.
