Ran electroencephalogram (EEG) tests on participants to collect, clean, and store brainwave data in Unix. Used visual artifact detection, extracted P3 and N1 components of event-related potentials (ERPs).Reviewed EEG data from multiple sites and entered relevant recordings into database server

The similarity between predictions of different mathematical models of egg shape geometry and natural egg shapes were assessed. Also, color of eggshells was measured by human observation, image J software and spectrophotometry analysis, in order to determine if egg coloration is a variable identity signaling.
