On the other hand, feedback and gratification are delayed as participants must wait a day or two for their results to come in.The time limit ensures that a participant will not be stuck with a boorish match for very long, and prevents participants from monopolizing one another's time.At the end of the event participants submit to the organizers a list of who they would like to provide their contact information to.If there is a match, contact information is forwarded to both parties.The first speed-dating event took place at Peet’s Café in Beverly Hills in late 1998.Usually advance registration is required for speed dating events.
Because the matching itself happens after the event, people do not feel pressured to select or reject each other in person.
In a 2012 study, researchers found that activation of specific brain regions while viewing images of opposite-sex speed dating participants was predictive of whether or not a participant would later pursue or reject the viewed participants at an actual speed dating event.
Men and women made decisions in a similar manner which incorporated the physical attractiveness and likability of the viewed participants in their evaluation.
Requirement for each event vary with the organizer.
Specific age range based on gender is a common restriction for events.
