This project is part three of a longitudinal twin study on attention and cognition. This project included the measurement eleven years after baseline and particularly focused on performance pressure. Twins that participated in the previous projects as preschoolers or preteens, were invited again, but additional twin pairs were recruited into the project. Cognitive abilities were measured with computerized tests which took place at the VU: a working memory capacity task, a mental rotation task (MRT) and the Advanced Raven’s Progressive Matrices, which measures intelligence. During the Raven and MRT, participants were subjected to either high pressure or low pressure from the test assistants. During the assessment tasks heart rate, cardiac sympathetic and parasympathetic control were measured using the Ambulatory Monitoring System (AMS) device. The tasks were followed by questionnaires about task perception and social comparison.
